Detects the creation or modification of scheduled tasks using the 'schtasks.exe' utility, specifically looking for indicators associated with persistence mechanisms such as task names or commands like 'StandAloneOneDriveUpdater-2626' and 'Automata-20.exe'.
Detects potential command and control (C2) beaconing activity to GitHub repository API endpoints. The rule monitors for a high frequency of requests to specific file names commonly associated with C2 payloads (e.g., command.txt, results.txt, heartbeat.txt) and employs statistical analysis to identify consistent, non-random connection patterns that deviate from expected business usage.
Detects the execution of LNK files that launch cmd.exe to execute batch script files (e.g., .bat). This pattern is frequently used in malicious infection chains, such as those leveraged by Transparent Tribe (APT36), where ISO or ZIP archives contain LNK files masquerading as document files to trick users into executing malicious scripts.
Detects malicious LNK files associated with the Transparent Tribe (APT36) campaign, which are designed to execute concealed batch scripts (e.g., doxc.bat, config.bat) via cmd.exe. These files are typically disguised as documents (resumes, details) to facilitate the deployment of secondary payloads like CrimsonRAT.
This rule detects network traffic patterns associated with the PSNATCH malware exfiltrating data to GitHub. It specifically identifies HTTP requests to 'api.github.com' using the custom 'SmartUploader' User-Agent string, which is characteristic of this malware's exfiltration behavior.
Detects network activity associated with the RUSTYSHADE malware, specifically identifying the 'HCENC1:' prefix used in HTTP requests to encapsulate AES-256-GCM encrypted command and control traffic directed towards GitHub API channels.
This rule detects network traffic patterns indicative of the Transparent Tribe threat group using the GitHub API for command-and-control (C2) operations. It specifically identifies HTTP requests to GitHub's content API that attempt to access or exchange files named 'command.txt', 'results.txt', 'heartbeat.txt', or 'screenshot.png', which are known indicators of this actor's C2 communication strategy.
Detects persistence mechanisms used by a Golang RAT, specifically targeting the creation of a 'DailyFitnessTracker' registry value in the HKCU Run key using reg.exe or PowerShell, and the placement of 'FitnessMonitor.exe' into the Windows Startup folder.
Detects execution of shell commands by cmd.exe in conjunction with the creation or modification of 'command.txt' or 'results.txt' files, which are indicative of the RUSTYSHADE backdoor's C2 synchronization behavior.
Detects execution of APT36's RUSTYSHADE backdoor, typically delivered via a DriverInstaller executable or zip file, and specifically tracks downloads from Backblaze B2 storage buckets using PowerShell.
