Query: hunt for Browser Session Hijacking activity
Matching passage: T1185 Browser Session Hijacking. Tactics: collection. Description: Adversaries may take advantage of security vulnerabilities and inherent functionality in browser software to change content, modify user-behaviors, and intercept information as part of various browser session hijacking techniques.(Citation: Wikipedia Man in the Browser) A specific example is when an adversary injects software into a browser that allows them to inherit cookies, HTTP sessions, and SSL client certificates of a user then use the browser as a way to pivot into an authenticated intranet.(Citation: Cobalt Strike Browser Pivot)(Citation: ICEBRG Chrome Extensions) Executing browser-based behaviors such as pivoting may require specific process permissions, such as <code>SeDebugPrivilege</code> and/or high-integrity/administrator rights. Another example involves pivoting browser traffic from the adversary's browser through the user's browser by setting up a proxy which will redirect web traffic. This does not alter the user's traffic in any way, and the proxy connection can be severed as soon as the browser is closed. The adversary assumes the security context of whichever browser process the proxy is injected into. Browsers typically create a new process for each tab that is opened and permissions and certificates are separated accordingly. With these permissions, an adversary could potentially browse to any resource on an intranet, such as [Sharepoint](https://attack.mitre.org/techniques/T1213/002) or webmail, that is accessible through the browser and which the browser has sufficient permissions. Browser pivoting may also bypass security provided by 2-factor authentication.(Citation: cobaltstrike manual)

Interactive command shells may be in use, and common functionality within [cmd](https://attack.mitre.org/software/S0106) may be used to gather information. Some adversaries may also use [Automated Collection](https://attack.mitre.org/techniques/T1119) on removable media.

Query: Encoded PowerShell / command-line abuse matching Proc Filesystem
Matching passage: T1003.007 Proc Filesystem. Tactics: credential access. Description: Adversaries may gather credentials from the proc filesystem or `/proc`. The proc filesystem is a pseudo-filesystem used as an interface to kernel data structures for Linux based systems managing virtual memory. For each process, the `/proc/<PID>/maps` file shows how memory is mapped within the process’s virtual address space. And `/proc/<PID>/mem`, exposed for debugging purposes, provides access to the process’s virtual address space.(Citation: Picus Labs Proc cump 2022)(Citation: baeldung Linux proc map 2022) When executing with root privileges, adversaries can search these memory locations for all processes on a system that contain patterns indicative of credentials. Adversaries may use regex patterns, such as <code>grep -E "^[0-9a-f-]* r" /proc/"$pid"/maps | cut -d' ' -f 1</code>, to look for fixed strings in memory structures or cached hashes.(Citation: atomic-red proc file system) When running without privileged access, processes can still view their own virtual memory locations. Some services or programs may save credentials in clear text inside the process’s memory.(Citation: MimiPenguin GitHub May 2017)(Citation: Polop Linux PrivEsc Gitbook) If running as or with the permissions of a web browser, a process can search the `/maps` & `/mem` locations for common website credential patterns (that can also be used to find adjacent memory within the same structure) in which hashes or cleartext credentials may be located.
Near-miss passage: T1003.002 Security Account Manager. Tactics: credential access. Description: Adversaries may attempt to extract credential material from the Security Account Manager (SAM) database either through in-memory techniques or through the Windows Registry where the SAM database is stored. The SAM is a database file that contains local accounts for the host, typically those found with the <code>net user</code> command. Enumerating the SAM database requires SYSTEM level access. A number of tools can be used to retrieve the SAM file through in-memory techniques: * pwdumpx.exe * [gsecdump](https://attack.mitre.org/software/S0008) * [Mimikatz](https://attack.mitre.org/software/S0002) * secretsdump.py Alternatively, the SAM can be extracted from the Registry with Reg: * <code>reg save HKLM\sam sam</code> * <code>reg save HKLM\system system</code> Creddump7 can then be used to process the SAM database locally to retrieve hashes.(Citation: GitHub Creddump7) Notes: * RID 500 account is the local, built-in administrator. * RID 501 is the guest account. * User accounts start with a RID of 1,000+.
Query: indicators of Remote Access Hardware
Matching passage: T1219.003 Remote Access Hardware. Tactics: command and control. Description: An adversary may use legitimate remote access hardware to establish an interactive command and control channel to target systems within networks. These services, including IP-based keyboard, video, or mouse (KVM) devices such as TinyPilot and PiKVM, are commonly used as legitimate tools and may be allowed by peripheral device policies within a target environment. Remote access hardware may be physically installed and used post-compromise as an alternate communications channel for redundant access or as a way to establish an interactive remote session with the target system. Using hardware-based remote access tools may allow threat actors to bypass software security solutions and gain more control over the compromised device(s).(Citation: Palo Alto Unit 42 North Korean IT Workers 2024)(Citation: Google Cloud Threat Intelligence DPRK IT Workers 2024)
Near-miss passage: T1219.002 Remote Desktop Software. Tactics: command and control. Description: An adversary may use legitimate desktop support software to establish an interactive command and control channel to target systems within networks. Desktop support software provides a graphical interface for remotely controlling another computer, transmitting the display output, keyboard input, and mouse control between devices using various protocols. Desktop support software, such as `VNC`, `Team Viewer`, `AnyDesk`, `ScreenConnect`, `LogMein`, `AmmyyAdmin`, and other remote monitoring and management (RMM) tools, are commonly used as legitimate technical support software and may be allowed by application control within a target environment.(Citation: Symantec Living off the Land)(Citation: CrowdStrike 2015 Global Threat Report)(Citation: CrySyS Blog TeamSpy) Remote access modules/features may also exist as part of otherwise existing software such as Zoom or Google Chrome’s Remote Desktop.(Citation: Google Chrome Remote Desktop)(Citation: Chrome Remote Desktop)
