Infiltration

Thursday

Attack

The network event indicates an 'Infiltration' attack. The event shows multiple connection attempts from the same source IP to the same destination IP. These connections are characterized by various TCP flags, such as SYN, FIN, RST, PSH, and ACK, suggesting sophisticated behavior to evade detection and maintain persistence. This pattern of behavior is indicative of an attacker who has already infiltrated the network and is attempting to maintain access or exfiltrate data while avoiding detection. The high number of packets and bytes exchanged, along with the prolonged flow durations and usage of multiple TCP flags, suggest efforts to manipulate or exploit the target system's vulnerabilities.

Normal

The network event described in the Suricata logs indicates normal behavior. This classification implies that the observed network activity does not exhibit any characteristics associated with malicious intent or attack patterns. Typical signs of attacks, such as unusual traffic patterns, suspicious connection attempts, or abnormal data exchanges, are absent. The network interactions recorded in the logs conform to expected and legitimate usage patterns, suggesting routine and benign operations.

Infiltration

Thursday

Attack

The network event indicates an 'Infiltration' attack. The event shows multiple connection attempts from the same source IP to the same destination IP. These connections are characterized by various TCP flags, such as SYN, FIN, RST, PSH, and ACK, suggesting sophisticated behavior to evade detection and maintain persistence. This pattern of behavior is indicative of an attacker who has already infiltrated the network and is attempting to maintain access or exfiltrate data while avoiding detection. The high number of packets and bytes exchanged, along with the prolonged flow durations and usage of multiple TCP flags, suggest efforts to manipulate or exploit the target system's vulnerabilities.

Portscan

Friday

Attack

The network event indicates a Portscan. Portscans involve scanning multiple ports on a target machine to identify open ports and services. Typically, the logs show multiple short-lived connection attempts from the same source IP to different destination ports. These connections are characterized by SYN, RST, and ACK flags, minimal data exchange, and immediate termination, often due to timeouts. This pattern of behavior is consistent with port scanning activity where the objective is to probe the target machine for open ports without establishing full connections.

Attack

The network event indicates a DDoS. DDoS attacks involve overwhelming the target system with a high frequency of requests. Typically, the logs show multiple short-lived connection attempts from various source IPs to the same destination IP, often on a common port like port 80. These connections are characterized by repeated TCP flags such as SYN, FIN, RST, PSH, and ACK, minimal data exchange, and frequent timeouts or resets. This pattern of behavior is consistent with DDoS activity, where the objective is to exhaust the target's resources and disrupt normal service.

Portscan

Friday

Attack

The network event indicates a Portscan. Portscans involve scanning multiple ports on a target machine to identify open ports and services. Typically, the logs show multiple short-lived connection attempts from the same source IP to different destination ports. These connections are characterized by SYN, RST, and ACK flags, minimal data exchange, and immediate termination, often due to timeouts. This pattern of behavior is consistent with port scanning activity where the objective is to probe the target machine for open ports without establishing full connections.

BENIGN

Wednesday

Normal

The network event described in the Suricata logs indicates normal behavior. This classification implies that the observed network activity does not exhibit any characteristics associated with malicious intent or attack patterns. Typical signs of attacks, such as unusual traffic patterns, suspicious connection attempts, or abnormal data exchanges, are absent. The network interactions recorded in the logs conform to expected and legitimate usage patterns, suggesting routine and benign operations.

Botnet

Friday

Attack

The network event indicates a Botnet. Botnet activities involve coordinated attacks from multiple compromised machines. Typically, the logs show traffic patterns indicative of control and command communication between the compromised machines and the command server. High volumes of data transfer, frequent anomalies, and suspicious HTTP traffic with repetitive patterns are observed. Additionally, the logs show specific bot IDs and system information, which are typical indicators of botnet communication.

Infiltration

Thursday

Attack

The network event indicates an 'Infiltration' attack. The event shows multiple connection attempts from the same source IP to the same destination IP. These connections are characterized by various TCP flags, such as SYN, FIN, RST, PSH, and ACK, suggesting sophisticated behavior to evade detection and maintain persistence. This pattern of behavior is indicative of an attacker who has already infiltrated the network and is attempting to maintain access or exfiltrate data while avoiding detection. The high number of packets and bytes exchanged, along with the prolonged flow durations and usage of multiple TCP flags, suggest efforts to manipulate or exploit the target system's vulnerabilities.

DoS Hulk

Wednesday

Attack

The network event indicates a DoS Hulk. DoS Hulk attacks involve sending a high frequency of HTTP requests to overwhelm the target server. Typically, the logs show multiple connection attempts from the same source IP to the same destination IP, with each connection being short-lived and frequently timed out. These connections are characterized by repeated TCP flags such as SYN, FIN, RST, PSH, and ACK, minimal data exchange, and immediate termination. This pattern of behavior is consistent with DoS Hulk attacks, where the objective is to disrupt the target server's normal operations by overwhelming it with excessive requests.

Botnet

Friday

Attack

The network event indicates a Botnet. Botnet activities involve coordinated attacks from multiple compromised machines. Typically, the logs show traffic patterns indicative of control and command communication between the compromised machines and the command server. High volumes of data transfer, frequent anomalies, and suspicious HTTP traffic with repetitive patterns are observed. Additionally, the logs show specific bot IDs and system information, which are typical indicators of botnet communication.

Normal

The network event described in the Suricata logs indicates normal behavior. This classification implies that the observed network activity does not exhibit any characteristics associated with malicious intent or attack patterns. Typical signs of attacks, such as unusual traffic patterns, suspicious connection attempts, or abnormal data exchanges, are absent. The network interactions recorded in the logs conform to expected and legitimate usage patterns, suggesting routine and benign operations.

DoS Slowloris

Wednesday

Attack

The network event indicates a DoS Slowloris. DoS Slowloris attacks involve sending partial HTTP requests to the target server, keeping connections open as long as possible. Typically, the logs show multiple long-lived connections with minimal data exchange, aiming to exhaust the target server's resources by maintaining numerous open connections. Additionally, the logs contain multiple `anomaly` events indicating `UNABLE_TO_MATCH_RESPONSE_TO_REQUEST`, which is consistent with incomplete HTTP requests. These characteristics align with the behavior of DoS Slowloris attacks, which aim to overwhelm the server by keeping numerous connections open with incomplete requests.

Normal

The network event described in the Suricata logs indicates normal behavior. This classification implies that the observed network activity does not exhibit any characteristics associated with malicious intent or attack patterns. Typical signs of attacks, such as unusual traffic patterns, suspicious connection attempts, or abnormal data exchanges, are absent. The network interactions recorded in the logs conform to expected and legitimate usage patterns, suggesting routine and benign operations.

Attack

The network event indicates a Botnet. Botnet activities involve coordinated attacks from multiple compromised machines. Typically, the logs show traffic patterns indicative of control and command communication between the compromised machines and the command server. High volumes of data transfer, frequent anomalies, and suspicious HTTP traffic with repetitive patterns are observed. Additionally, the logs show specific bot IDs and system information, which are typical indicators of botnet communication.

DoS Hulk

Wednesday

Attack

The network event indicates a DoS Hulk. DoS Hulk attacks involve sending a high frequency of HTTP requests to overwhelm the target server. Typically, the logs show multiple connection attempts from the same source IP to the same destination IP, with each connection being short-lived and frequently timed out. These connections are characterized by repeated TCP flags such as SYN, FIN, RST, PSH, and ACK, minimal data exchange, and immediate termination. This pattern of behavior is consistent with DoS Hulk attacks, where the objective is to disrupt the target server's normal operations by overwhelming it with excessive requests.

Infiltration

Thursday

Attack

The network event indicates an 'Infiltration' attack. The event shows multiple connection attempts from the same source IP to the same destination IP. These connections are characterized by various TCP flags, such as SYN, FIN, RST, PSH, and ACK, suggesting sophisticated behavior to evade detection and maintain persistence. This pattern of behavior is indicative of an attacker who has already infiltrated the network and is attempting to maintain access or exfiltrate data while avoiding detection. The high number of packets and bytes exchanged, along with the prolonged flow durations and usage of multiple TCP flags, suggest efforts to manipulate or exploit the target system's vulnerabilities.

FTP-Patator

Tuesday

Attack

The network event indicates a FTP-Patator. FTP-Patator attacks involve brute force attempts to gain access to an FTP server. Typically, the logs show multiple login attempts from the same source IP to the FTP server, often with varied credentials. This pattern of behavior is consistent with brute force attacks aiming to discover valid username and password combinations. Additionally, the logs show multiple failed login attempts with a `530 Login incorrect` response, indicating invalid credentials, and short-lived connections frequently terminated with `RST` or `FIN` flags. These characteristics align with the behavior of automated tools like FTP-Patator, which issue numerous login attempts in a short time frame.

Normal

The network event described in the Suricata logs indicates normal behavior. This classification implies that the observed network activity does not exhibit any characteristics associated with malicious intent or attack patterns. Typical signs of attacks, such as unusual traffic patterns, suspicious connection attempts, or abnormal data exchanges, are absent. The network interactions recorded in the logs conform to expected and legitimate usage patterns, suggesting routine and benign operations.

DoS Hulk

Wednesday

Attack

The network event indicates a DoS Hulk. DoS Hulk attacks involve sending a high frequency of HTTP requests to overwhelm the target server. Typically, the logs show multiple connection attempts from the same source IP to the same destination IP, with each connection being short-lived and frequently timed out. These connections are characterized by repeated TCP flags such as SYN, FIN, RST, PSH, and ACK, minimal data exchange, and immediate termination. This pattern of behavior is consistent with DoS Hulk attacks, where the objective is to disrupt the target server's normal operations by overwhelming it with excessive requests.

Portscan

Friday

Attack

The network event indicates a Portscan. Portscans involve scanning multiple ports on a target machine to identify open ports and services. Typically, the logs show multiple short-lived connection attempts from the same source IP to different destination ports. These connections are characterized by SYN, RST, and ACK flags, minimal data exchange, and immediate termination, often due to timeouts. This pattern of behavior is consistent with port scanning activity where the objective is to probe the target machine for open ports without establishing full connections.

Infiltration

Thursday

Attack

The network event indicates an 'Infiltration' attack. The event shows multiple connection attempts from the same source IP to the same destination IP. These connections are characterized by various TCP flags, such as SYN, FIN, RST, PSH, and ACK, suggesting sophisticated behavior to evade detection and maintain persistence. This pattern of behavior is indicative of an attacker who has already infiltrated the network and is attempting to maintain access or exfiltrate data while avoiding detection. The high number of packets and bytes exchanged, along with the prolonged flow durations and usage of multiple TCP flags, suggest efforts to manipulate or exploit the target system's vulnerabilities.

This pattern of behavior is indicative of an attacker who has already infiltrated the network and is attempting to maintain access or exfiltrate data while avoiding detection. The high number of packets and bytes exchanged, along with the prolonged flow durations and usage of multiple TCP flags, suggest efforts to manipulate or exploit the target system's vulnerabilities.

Portscan

Friday

Attack

The network event indicates a Portscan. Portscans involve scanning multiple ports on a target machine to identify open ports and services. Typically, the logs show multiple short-lived connection attempts from the same source IP to different destination ports. These connections are characterized by SYN, RST, and ACK flags, minimal data exchange, and immediate termination, often due to timeouts. This pattern of behavior is consistent with port scanning activity where the objective is to probe the target machine for open ports without establishing full connections.

DoS Hulk

Wednesday

Attack

The network event indicates a DoS Hulk. DoS Hulk attacks involve sending a high frequency of HTTP requests to overwhelm the target server. Typically, the logs show multiple connection attempts from the same source IP to the same destination IP, with each connection being short-lived and frequently timed out. These connections are characterized by repeated TCP flags such as SYN, FIN, RST, PSH, and ACK, minimal data exchange, and immediate termination. This pattern of behavior is consistent with DoS Hulk attacks, where the objective is to disrupt the target server's normal operations by overwhelming it with excessive requests.

DoS Slowloris

Wednesday

Attack

The network event indicates a DoS Slowloris. DoS Slowloris attacks involve sending partial HTTP requests to the target server, keeping connections open as long as possible. Typically, the logs show multiple long-lived connections with minimal data exchange, aiming to exhaust the target server's resources by maintaining numerous open connections. Additionally, the logs contain multiple `anomaly` events indicating `UNABLE_TO_MATCH_RESPONSE_TO_REQUEST`, which is consistent with incomplete HTTP requests. These characteristics align with the behavior of DoS Slowloris attacks, which aim to overwhelm the server by keeping numerous connections open with incomplete requests.

BENIGN

Wednesday

Normal

The network event described in the Suricata logs indicates normal behavior. This classification implies that the observed network activity does not exhibit any characteristics associated with malicious intent or attack patterns. Typical signs of attacks, such as unusual traffic patterns, suspicious connection attempts, or abnormal data exchanges, are absent. The network interactions recorded in the logs conform to expected and legitimate usage patterns, suggesting routine and benign operations.

DoS Hulk

Wednesday

Attack

The network event indicates a DoS Hulk. DoS Hulk attacks involve sending a high frequency of HTTP requests to overwhelm the target server. Typically, the logs show multiple connection attempts from the same source IP to the same destination IP, with each connection being short-lived and frequently timed out. These connections are characterized by repeated TCP flags such as SYN, FIN, RST, PSH, and ACK, minimal data exchange, and immediate termination. This pattern of behavior is consistent with DoS Hulk attacks, where the objective is to disrupt the target server's normal operations by overwhelming it with excessive requests.

BENIGN

Tuesday

Normal

The network event described in the Suricata logs indicates normal behavior. This classification implies that the observed network activity does not exhibit any characteristics associated with malicious intent or attack patterns. Typical signs of attacks, such as unusual traffic patterns, suspicious connection attempts, or abnormal data exchanges, are absent. The network interactions recorded in the logs conform to expected and legitimate usage patterns, suggesting routine and benign operations.

DoS Hulk

Wednesday

Attack

The network event indicates a DoS Hulk. DoS Hulk attacks involve sending a high frequency of HTTP requests to overwhelm the target server. Typically, the logs show multiple connection attempts from the same source IP to the same destination IP, with each connection being short-lived and frequently timed out. These connections are characterized by repeated TCP flags such as SYN, FIN, RST, PSH, and ACK, minimal data exchange, and immediate termination. This pattern of behavior is consistent with DoS Hulk attacks, where the objective is to disrupt the target server's normal operations by overwhelming it with excessive requests.

Normal

The network event described in the Suricata logs indicates normal behavior. This classification implies that the observed network activity does not exhibit any characteristics associated with malicious intent or attack patterns. Typical signs of attacks, such as unusual traffic patterns, suspicious connection attempts, or abnormal data exchanges, are absent. The network interactions recorded in the logs conform to expected and legitimate usage patterns, suggesting routine and benign operations.

Attack

The network event indicates a DDoS. DDoS attacks involve overwhelming the target system with a high frequency of requests. Typically, the logs show multiple short-lived connection attempts from various source IPs to the same destination IP, often on a common port like port 80. These connections are characterized by repeated TCP flags such as SYN, FIN, RST, PSH, and ACK, minimal data exchange, and frequent timeouts or resets. This pattern of behavior is consistent with DDoS activity, where the objective is to exhaust the target's resources and disrupt normal service.

DoS Slowhttptest

Wednesday

Attack

The network event indicates a DoS Slowhttptest. DoS Slowhttptest attacks involve sending partial HTTP requests at a slow rate to keep connections open. Typically, the logs show multiple connections with minimal data exchange and prolonged open states, aiming to exhaust the target server's resources. Additionally, the logs contain multiple `anomaly` events indicating `APPLAYER_DETECT_PROTOCOL_ONLY_ONE_DIRECTION` and `UNABLE_TO_MATCH_RESPONSE_TO_REQUEST`, which is consistent with incomplete HTTP requests. These characteristics align with the behavior of DoS Slowhttptest attacks, which aim to overwhelm the server by keeping numerous connections open with partial and incomplete requests.

Normal

The network event described in the Suricata logs indicates normal behavior. This classification implies that the observed network activity does not exhibit any characteristics associated with malicious intent or attack patterns. Typical signs of attacks, such as unusual traffic patterns, suspicious connection attempts, or abnormal data exchanges, are absent. The network interactions recorded in the logs conform to expected and legitimate usage patterns, suggesting routine and benign operations.

The network event described in the Suricata logs indicates normal behavior. This classification implies that the observed network activity does not exhibit any characteristics associated with malicious intent or attack patterns. Typical signs of attacks, such as unusual traffic patterns, suspicious connection attempts, or abnormal data exchanges, are absent. The network interactions recorded in the logs conform to expected and legitimate usage patterns, suggesting routine and benign operations.

DDoS

Friday

Attack

The network event indicates a DDoS. DDoS attacks involve overwhelming the target system with a high frequency of requests. Typically, the logs show multiple short-lived connection attempts from various source IPs to the same destination IP, often on a common port like port 80. These connections are characterized by repeated TCP flags such as SYN, FIN, RST, PSH, and ACK, minimal data exchange, and frequent timeouts or resets. This pattern of behavior is consistent with DDoS activity, where the objective is to exhaust the target's resources and disrupt normal service.

Portscan

Friday

Attack

The network event indicates a Portscan. Portscans involve scanning multiple ports on a target machine to identify open ports and services. Typically, the logs show multiple short-lived connection attempts from the same source IP to different destination ports. These connections are characterized by SYN, RST, and ACK flags, minimal data exchange, and immediate termination, often due to timeouts. This pattern of behavior is consistent with port scanning activity where the objective is to probe the target machine for open ports without establishing full connections.

DoS Hulk

Wednesday

Attack

The network event indicates a DoS Hulk. DoS Hulk attacks involve sending a high frequency of HTTP requests to overwhelm the target server. Typically, the logs show multiple connection attempts from the same source IP to the same destination IP, with each connection being short-lived and frequently timed out. These connections are characterized by repeated TCP flags such as SYN, FIN, RST, PSH, and ACK, minimal data exchange, and immediate termination. This pattern of behavior is consistent with DoS Hulk attacks, where the objective is to disrupt the target server's normal operations by overwhelming it with excessive requests.

Normal

The network event described in the Suricata logs indicates normal behavior. This classification implies that the observed network activity does not exhibit any characteristics associated with malicious intent or attack patterns. Typical signs of attacks, such as unusual traffic patterns, suspicious connection attempts, or abnormal data exchanges, are absent. The network interactions recorded in the logs conform to expected and legitimate usage patterns, suggesting routine and benign operations.

Attack

The network event indicates a Botnet. Botnet activities involve coordinated attacks from multiple compromised machines. Typically, the logs show traffic patterns indicative of control and command communication between the compromised machines and the command server. High volumes of data transfer, frequent anomalies, and suspicious HTTP traffic with repetitive patterns are observed. Additionally, the logs show specific bot IDs and system information, which are typical indicators of botnet communication.

Infiltration

Thursday

Attack

The network event indicates an 'Infiltration' attack. The event shows multiple connection attempts from the same source IP to the same destination IP. These connections are characterized by various TCP flags, such as SYN, FIN, RST, PSH, and ACK, suggesting sophisticated behavior to evade detection and maintain persistence. This pattern of behavior is indicative of an attacker who has already infiltrated the network and is attempting to maintain access or exfiltrate data while avoiding detection. The high number of packets and bytes exchanged, along with the prolonged flow durations and usage of multiple TCP flags, suggest efforts to manipulate or exploit the target system's vulnerabilities.

Attack

The network event indicates a Portscan. Portscans involve scanning multiple ports on a target machine to identify open ports and services. Typically, the logs show multiple short-lived connection attempts from the same source IP to different destination ports. These connections are characterized by SYN, RST, and ACK flags, minimal data exchange, and immediate termination, often due to timeouts. This pattern of behavior is consistent with port scanning activity where the objective is to probe the target machine for open ports without establishing full connections.

Normal

The network event described in the Suricata logs indicates normal behavior. This classification implies that the observed network activity does not exhibit any characteristics associated with malicious intent or attack patterns. Typical signs of attacks, such as unusual traffic patterns, suspicious connection attempts, or abnormal data exchanges, are absent. The network interactions recorded in the logs conform to expected and legitimate usage patterns, suggesting routine and benign operations.

DoS Hulk

Wednesday

Attack

The network event indicates a DoS Hulk. DoS Hulk attacks involve sending a high frequency of HTTP requests to overwhelm the target server. Typically, the logs show multiple connection attempts from the same source IP to the same destination IP, with each connection being short-lived and frequently timed out. These connections are characterized by repeated TCP flags such as SYN, FIN, RST, PSH, and ACK, minimal data exchange, and immediate termination. This pattern of behavior is consistent with DoS Hulk attacks, where the objective is to disrupt the target server's normal operations by overwhelming it with excessive requests.

BENIGN

Wednesday

Normal

The network event described in the Suricata logs indicates normal behavior. This classification implies that the observed network activity does not exhibit any characteristics associated with malicious intent or attack patterns. Typical signs of attacks, such as unusual traffic patterns, suspicious connection attempts, or abnormal data exchanges, are absent. The network interactions recorded in the logs conform to expected and legitimate usage patterns, suggesting routine and benign operations.

Infiltration

Thursday

Attack

The network event indicates an 'Infiltration' attack. The event shows multiple connection attempts from the same source IP to the same destination IP. These connections are characterized by various TCP flags, such as SYN, FIN, RST, PSH, and ACK, suggesting sophisticated behavior to evade detection and maintain persistence. This pattern of behavior is indicative of an attacker who has already infiltrated the network and is attempting to maintain access or exfiltrate data while avoiding detection. The high number of packets and bytes exchanged, along with the prolonged flow durations and usage of multiple TCP flags, suggest efforts to manipulate or exploit the target system's vulnerabilities.

DoS Hulk

Wednesday

Attack

The network event indicates a DoS Hulk. DoS Hulk attacks involve sending a high frequency of HTTP requests to overwhelm the target server. Typically, the logs show multiple connection attempts from the same source IP to the same destination IP, with each connection being short-lived and frequently timed out. These connections are characterized by repeated TCP flags such as SYN, FIN, RST, PSH, and ACK, minimal data exchange, and immediate termination. This pattern of behavior is consistent with DoS Hulk attacks, where the objective is to disrupt the target server's normal operations by overwhelming it with excessive requests.

SSH-Patator

Tuesday

Attack

The network event indicates a SSH-Patator. SSH-Patator attacks involve brute force attempts to gain access to an SSH server. Typically, the logs show multiple login attempts from the same source IP to the SSH server, often with varied credentials. This pattern of behavior is consistent with brute force attacks aiming to discover valid username and password combinations. Additionally, the logs show multiple established connections that are short-lived, frequently terminated due to `timeout`, and detailed SSH protocol negotiations. These characteristics align with the behavior of automated tools like SSH-Patator, which issue numerous login attempts rapidly.

Normal

The network event described in the Suricata logs indicates normal behavior. This classification implies that the observed network activity does not exhibit any characteristics associated with malicious intent or attack patterns. Typical signs of attacks, such as unusual traffic patterns, suspicious connection attempts, or abnormal data exchanges, are absent. The network interactions recorded in the logs conform to expected and legitimate usage patterns, suggesting routine and benign operations.

The network event described in the Suricata logs indicates normal behavior. This classification implies that the observed network activity does not exhibit any characteristics associated with malicious intent or attack patterns. Typical signs of attacks, such as unusual traffic patterns, suspicious connection attempts, or abnormal data exchanges, are absent. The network interactions recorded in the logs conform to expected and legitimate usage patterns, suggesting routine and benign operations.

The network event indicates a Portscan. Portscans involve scanning multiple ports on a target machine to identify open ports and services. Typically, the logs show multiple short-lived connection attempts from the same source IP to different destination ports. These connections are characterized by SYN, RST, and ACK flags, minimal data exchange, and immediate termination, often due to timeouts. This pattern of behavior is consistent with port scanning activity where the objective is to probe the target machine for open ports without establishing full connections.

Normal

The network event described in the Suricata logs indicates normal behavior. This classification implies that the observed network activity does not exhibit any characteristics associated with malicious intent or attack patterns. Typical signs of attacks, such as unusual traffic patterns, suspicious connection attempts, or abnormal data exchanges, are absent. The network interactions recorded in the logs conform to expected and legitimate usage patterns, suggesting routine and benign operations.

Typically, the logs show multiple login attempts from the same source IP to the SSH server, often with varied credentials.

Additionally, the logs show multiple established connections that are short-lived, frequently terminated due to `timeout`, and detailed SSH protocol negotiations. These characteristics align with the behavior of automated tools like SSH-Patator, which issue numerous login attempts rapidly.

DDoS

Friday

Attack

The network event indicates a DDoS. DDoS attacks involve overwhelming the target system with a high frequency of requests. Typically, the logs show multiple short-lived connection attempts from various source IPs to the same destination IP, often on a common port like port 80. These connections are characterized by repeated TCP flags such as SYN, FIN, RST, PSH, and ACK, minimal data exchange, and frequent timeouts or resets. This pattern of behavior is consistent with DDoS activity, where the objective is to exhaust the target's resources and disrupt normal service.

SSH-Patator

Tuesday

Attack

The network event indicates a SSH-Patator. SSH-Patator attacks involve brute force attempts to gain access to an SSH server. Typically, the logs show multiple login attempts from the same source IP to the SSH server, often with varied credentials. This pattern of behavior is consistent with brute force attacks aiming to discover valid username and password combinations. Additionally, the logs show multiple established connections that are short-lived, frequently terminated due to `timeout`, and detailed SSH protocol negotiations. These characteristics align with the behavior of automated tools like SSH-Patator, which issue numerous login attempts rapidly.

DDoS

Friday

Attack

The network event indicates a DDoS. DDoS attacks involve overwhelming the target system with a high frequency of requests. Typically, the logs show multiple short-lived connection attempts from various source IPs to the same destination IP, often on a common port like port 80. These connections are characterized by repeated TCP flags such as SYN, FIN, RST, PSH, and ACK, minimal data exchange, and frequent timeouts or resets. This pattern of behavior is consistent with DDoS activity, where the objective is to exhaust the target's resources and disrupt normal service.
