Detects application log patterns indicative of a memory leak exploitation attempt against vLLM using the Python Imaging Library (PIL). This behavior is associated with an ASLR bypass technique leveraging BytesIO object manipulation, a prerequisite for a subsequent heap overflow vulnerability.
Detects network requests to Microsoft Graph API endpoints related to MFA method configuration. This pattern often indicates an adversary attempting to add, modify, or register new MFA authentication methods (such as phone-based methods) for an account to facilitate persistence or bypass security controls.
Detects Node.js process querying Ethereum blockchain for C2 address.
Detects malicious URLs sent via Microsoft Teams direct messages that contain known phishing TLDs, indicating potential phishing attempts or the use of Phishing-as-a-Service (PhaaS) infrastructure. The rule specifically targets one-on-one chats and filters for a broad list of suspicious top-level domains.
Detects stolen session token reuse to bypass MFA by correlating a successful SSO/VPN login from one IP with a subsequent successful login from a different IP using the same user agent context, or a user-agent change between sessions for the same user within a short window. Targets access broker technique where infostealer-harvested session cookies are replayed from different source IPs.
Detects persistence via registry modification commonly associated with RomCom adversary activity (e.g., Mythic, SnipBot, MeltingClaw) post-CVE-2025-8088 exploitation.
Detects the specific ShinyHunters lateral movement pattern involving automated SSH credential spraying using 'sshpass' or rapid SSH connections to multiple hosts with PeopleSoft admin accounts, often after reading '/etc/hosts'. The rule identifies suspicious SSH activity by looking for 'sshpass' execution or multiple 'ssh' commands with specific PeopleSoft-related usernames, potentially preceded by commands to read '/etc/hosts'.
Detects the use of 'sshpass' to automate SSH authentication, often used for lateral movement. The rule monitors command lines for the 'sshpass' utility combined with 'StrictHostKeyChecking=no' and specific service accounts (psoft, oracle, linuxadm) often targeted by threat actors such as ShinyHunters.
Detects the creation or modification of a file named 'help.php' within directories associated with REDCap deployments. This activity is a known persistence mechanism used by threat actors like UNC6508 to establish web shell access.
This query detects the creation of local user accounts on Linux systems using the 'useradd' or 'adduser' commands. Monitoring for local account creation is crucial as adversaries may create accounts for persistence, privilege escalation, or to facilitate lateral movement.
