Query: indicators of OS Exhaustion Flood
Matching passage: T1499.001 OS Exhaustion Flood. Tactics: impact. Description: Adversaries may launch a denial of service (DoS) attack targeting an endpoint's operating system (OS). A system's OS is responsible for managing the finite resources as well as preventing the entire system from being overwhelmed by excessive demands on its capacity. These attacks do not need to exhaust the actual resources on a system; the attacks may simply exhaust the limits and available resources that an OS self-imposes. Different ways to achieve this exist, including TCP state-exhaustion attacks such as SYN floods and ACK floods.(Citation: Arbor AnnualDoSreport Jan 2018) With SYN floods, excessive amounts of SYN packets are sent, but the 3-way TCP handshake is never completed. Because each OS has a maximum number of concurrent TCP connections that it will allow, this can quickly exhaust the ability of the system to receive new requests for TCP connections, thus preventing access to any TCP service provided by the server.(Citation: Cloudflare SynFlood) ACK floods leverage the stateful nature of the TCP protocol. A flood of ACK packets are sent to the target. This forces the OS to search its state table for a related TCP connection that has already been established. Because the ACK packets are for connections that do not exist, the OS will have to search the entire state table to confirm that no match exists. When it is necessary to do this for a large flood of packets, the computational requirements can cause the server to become sluggish and/or unresponsive, due to the work it must do to eliminate the rogue ACK packets. This greatly reduces the resources available for providing the targeted service.(Citation: Corero SYN-ACKflood)
Near-miss passage: T1499.004 Application or System Exploitation. Tactics: impact. Description: Adversaries may exploit software vulnerabilities that can cause an application or system to crash and deny availability to users. (Citation: Sucuri BIND9 August 2015) Some systems may automatically restart critical applications and services when crashes occur, but they can likely be re-exploited to cause a persistent denial of service (DoS) condition. Adversaries may exploit known or zero-day vulnerabilities to crash applications and/or systems, which may also lead to dependent applications and/or systems to be in a DoS condition. Crashed or restarted applications or systems may also have other effects such as [Data Destruction](https://attack.mitre.org/techniques/T1485), [Firmware Corruption](https://attack.mitre.org/techniques/T1495), [Service Stop](https://attack.mitre.org/techniques/T1489) etc. which may further cause a DoS condition and deny availability to critical information, applications and/or systems.

Query: intelligence brief on T1683
Matching passage: T1683 Generate Content. Tactics: resource development. Description: Adversaries may create or generate content to support targeting and operations. This content may be used to establish personas, impersonate known individuals or organizations, and support [Social Engineering](https://attack.mitre.org/techniques/T1684), fraud, or influence activities. Written materials, audio, images, video, or other media may be developed and tailored to the target and objective.(Citation: IBM AI-Generated Content) Content development may occur prior to or during an operation. Adversaries may develop or generate content in-house, source it through third parties, or produce it using AI-assisted tools. Adversaries may use AI to research targets, develop pretexts, and better understand the organizations and individuals they intend to target or deceive prior to generating content (i.e., [Query Public AI Services](https://attack.mitre.org/techniques/T1682)); for obtaining access to AI tools used in content generation, see [Artificial Intelligence](https://attack.mitre.org/techniques/T1588/007). Content may be leveraged in support of techniques such as [Phishing](https://attack.mitre.org/techniques/T1566), [Phishing for Information](https://attack.mitre.org/techniques/T1598), [Social Engineering](https://attack.mitre.org/techniques/T1684), [Financial Theft](https://attack.mitre.org/techniques/T1657), or [Establish Accounts](https://attack.mitre.org/techniques/T1585).

Near-miss passage: T1683.002 Audio-Visual Content. Tactics: resource development. Description: Adversaries may create or manipulate audio, image, and video content to support targeting and malicious operations. Adversaries may also use synthetic voice recordings, real-time altered audio or video during live interactions, fabricated profile photos and identity documents, or video content depicting fabricated or impersonated individuals.(Citation: Nov AI Threat Tracker) Content may be produced manually through editing tools, generated using AI-assisted tools, or produced using third-party synthetic services.(Citation: FBI 2025 AI Generate Content)(Citation: Europol Deepfakes) AI-assisted tools have enabled adversaries to produce synthetic media at scale and generate content that is more difficult to identify as inauthentic. Audio-visual content produced through these methods may be used in support of other techniques, such as [Phishing](https://attack.mitre.org/techniques/T1660), [Spearphishing via Service](https://attack.mitre.org/techniques/T1566/003), [Phishing for Information](https://attack.mitre.org/techniques/T1598), [Internal Spearphishing](https://attack.mitre.org/techniques/T1534), [Social Engineering](https://attack.mitre.org/techniques/T1684), [Financial Theft](https://attack.mitre.org/techniques/T1657), or [Establish Accounts](https://attack.mitre.org/techniques/T1585).
Query: SIEM correlation: stealth activity consistent with LC_MAIN Hijacking
Matching passage: T1149 LC_MAIN Hijacking. Tactics: stealth. Description: **This technique has been deprecated and should no longer be used.** As of OS X 10.8, mach-O binaries introduced a new header called LC_MAIN that points to the binary’s entry point for execution. Previously, there were two headers to achieve this same effect: LC_THREAD and LC_UNIXTHREAD (Citation: Prolific OSX Malware History). The entry point for a binary can be hijacked so that initial execution flows to a malicious addition (either another section or a code cave) and then goes back to the initial entry point so that the victim doesn’t know anything was different (Citation: Methods of Mac Malware Persistence). By modifying a binary in this way, application whitelisting can be bypassed because the file name or application path is still the same.
Near-miss passage: T1027.009 Embedded Payloads. Tactics: stealth. Description: Adversaries may embed payloads within other files to conceal malicious content from defenses. Otherwise seemingly benign files (such as scripts and executables) may be abused to carry and obfuscate malicious payloads and content. In some cases, embedded payloads may also enable adversaries to [Subvert Trust Controls](https://attack.mitre.org/techniques/T1553) by not impacting execution controls such as digital signatures and notarization tickets.(Citation: Sentinel Labs) Adversaries may embed payloads in various file formats to hide payloads.(Citation: Microsoft Learn) This is similar to [Steganography](https://attack.mitre.org/techniques/T1027/003), though does not involve weaving malicious content into specific bytes and patterns related to legitimate digital media formats.(Citation: GitHub PSImage) For example, adversaries have been observed embedding payloads within or as an overlay of an otherwise benign binary.(Citation: Securelist Dtrack2) Adversaries have also been observed nesting payloads (such as executables and run-only scripts) inside a file of the same format.(Citation: SentinelLabs reversing run-only applescripts 2021) Embedded content may also be used as [Process Injection](https://attack.mitre.org/techniques/T1055) payloads used to infect benign system processes.(Citation: Trend Micro) These embedded then injected payloads may be used as part of the modules of malware designed to provide specific features such as encrypting C2 communications in support of an orchestrator module. For example, an embedded module may be injected into default browsers, allowing adversaries to then communicate via the network.(Citation: Malware Analysis Report ComRAT)
