Detects execution of the "cloudflared" tool to connect back to a tunnel. This was seen used by threat actors to maintain persistence and remote access to compromised networks.
Detects RAR usage that creates an archive from a suspicious folder, either a system folder or one of the folders often used by attackers for staging purposes
Detects the execution of a renamed "cloudflared" binary.
Detects a commandline containing references to the Microsoft Teams database or cookies files from a process other than Teams.
The database might contain authentication tokens and other sensitive information about the logged in accounts.
The database might contain authentication tokens and other sensitive information about the logged in accounts.
Detects Certipy execution, a tool for Active Directory Certificate Services enumeration and abuse based on PE metadata characteristics and common command line arguments. Certipy can be used to enumerate Active Directory Certificate Services (AD CS) for misconfigurations, request certificates, and perform various attacks such as forging authentication certificates (ESC1, ESC2, ESC3, ESC4, ESC6, ESC7, ESC8, ESC9, ESC10). The rule looks for the executable name, original file name, description containing 'Certipy', or specific command-line arguments and flags commonly used by Certipy.
Detects when attackers or tools disable Windows Defender functionalities by modifying specific registry keys. This rule looks for changes to various Windows Defender related registry paths, specifically setting DWORD values to either 0x00000001 (to disable certain features) or 0x00000000 (to disable other features like Tamper Protection or PUA Protection).
Detects the creation of files with names commonly used by various memory dumping tools to extract credentials from the Local Security Authority Subsystem Service (LSASS) process memory. This includes specific filenames and patterns associated with tools like Procdump, MirrorDump, PPLBlade, RustiveDump, NativeDump, and Nanodump.
Detects process access requests from known hacktool processes based on their executable names. This rule targets a wide range of tools commonly used for credential dumping, privilege escalation, and other malicious activities, including Mimikatz, various Potato exploits, and other offensive security tools. The detection focuses on the 'SourceImage' field, indicating the process initiating the access.
Detects when a memory process image does not match the disk image, indicative of process hollowing. This rule specifically looks for 'Image is replaced' events and filters out common legitimate applications that might exhibit similar behavior, such as applications in 'Program Files', 'Windows\System32\wbem\WMIADAP.exe', 'Windows\SysWOW64\wbem\WMIADAP.exe', Opera, and Edge.
Detects the execution of a specific binary identified by its filename and SHA256 hash. This binary is associated with the Lace Tempest threat group and is used to load additional malware, as reported by the SysAid Team. The detection specifically looks for a process created from the path ':\Program Files\SysAidServer\tomcat\webapps\usersfiles\user.exe' or a process with the SHA256 hash 'B5ACF14CDAC40BE590318DEE95425D0746E85B1B7B1CBD14DA66F21F2522BF4D'.
