Detects executable files containing XOR-obfuscated strings associated with BabylonRAT capabilities, including browser credential theft, keylogging, HOSTS file manipulation, DDoS, and remote dynamic API resolution. This rule identifies patterns commonly used to evade static analysis.
Detects network traffic associated with the GhostCode phishing kit, specifically identifying API requests to a harvester service and subsequent responses indicating the activation of FlashProxy residential proxy services. These indicators suggest an attacker is leveraging proxy infrastructure to manage command-and-control communications and mask the source of malicious activity.
Detects incoming HTTP GET requests targeting known API endpoints associated with the GhostCode phishing kit. These endpoints (/api/harvester) are used by the phishing kit to poll for session details, device codes, or flow identifiers, characteristic of credential harvesting operations.
This rule detects device registration, joining, or enrollment events where the DeviceDisplayName follows a specific naming pattern (e.g., 'word-word-alphanumeric-word-hash'). It groups these events by device and user to track frequency, which can help identify potentially automated or malicious device registration behavior.
Detects the execution of PowerShell with suspicious command line flags (such as hidden windows, bypass execution policies, or encoded commands) where the parent process is a shortcut (.lnk) file. This is a common technique used by attackers to execute malicious scripts via phishing or social engineering, where a user is tricked into clicking a malicious link file.
This rule detects network activity (HTTP requests or DNS queries) interacting with specific suspicious domains that mimic Microsoft 365, Purview, or DocuSign authentication pages. These domains are identified by specific naming patterns and content markers indicative of credential harvesting or device code phishing attacks.
Detects DNS queries and TLS SNI traffic directed towards known typosquatted domains associated with the SilkParasite campaign. These domains are designed to impersonate Central Asian government, energy, and telecommunications entities to facilitate malicious activity.
Detects instances where a user successfully authenticates using the OAuth Device Code flow followed by subsequent mailbox operations (such as reading, sending, or deleting items) from a different IP address within a 10-minute window. This behavior is a strong indicator of adversary-in-the-middle phishing attacks where an attacker captures a session token and utilizes it from a remote location.
Detects the creation or registration of scheduled tasks that masquerade as Google Chrome updates but point to non-standard executable paths. This is a common technique used by malware to establish persistence by mimicking legitimate software update tasks.
This rule detects PowerShell commands that enumerate system, security, or virtualization-related artifacts. It specifically looks for the usage of WMI and PowerShell cmdlets (e.g., Get-Process, Get-WmiObject) to query for known analysis tools, debuggers, or virtualization software strings, which is a common behavior of malware attempting to identify and evade sandbox or analyst environments.
