Detects the Apache ActiveMQ process (java.exe or wrapper.exe) spawning a command shell or web utility. This behavior is a strong indicator of post-exploitation activity following the exploitation of vulnerabilities like CVE-2023-46604, often used as an entry point for ransomware like LockBit 5.0.
This rule detects various stages of an attack chain, starting from an Apache ActiveMQ exploit (CVE-2023-46604) leading to LockBit-style ransomware. It identifies process creation anomalies (java.exe spawning certutil.exe for downloads), network connections to known Metasploit C2 infrastructure, the presence of specific ransomware file hashes, and attempts to clear Windows event logs, all indicative of the described attack scenario.
Detects the Java process, commonly associated with Apache ActiveMQ, spawning certutil.exe to download a file from a remote URL. This behavior is a strong indicator of initial compromise via vulnerabilities like CVE-2023-46604.
This rule detects suspicious Spring bean XML content, specifically looking for indicators related to the exploitation of Apache ActiveMQ CVE-2023-46604. It targets XML payloads that attempt to execute commands using 'ProcessBuilder' and download files via 'certutil -urlcache' from an HTTP source, consistent with observed attack patterns.
Detects suspicious user agent strings commonly used by various malware families and Remote Access Trojans (RATs) in proxy logs. This rule identifies specific user-agent patterns associated with known threats like DragonOK, PlugX, HTTPBrowser RAT, njRAT, ZeroAccess, Dyre, Upatre, Ghost419, W32/Renos.Downloader, Kazy, Sality, Fareit, Toby web shell, Loki Bot, Pony, MacControl malware, Zebrocy, Ursnif, Emotet, Lockbit, Quasar RAT, Havana, AntSword, Racoon Stealer, AresLoader, Lilith Stealer, SVC Loader, WSHRAT, Zerobot, Nymaim, DarkCloud, BunnyStealer, SparkRAT, B4B3RAT, and Latrodectus loader.
