View Detections Join Threat Bounty AsyncRAT Payloads and 3LOSH AnalysisĪ multi-stage infection process leveraged by AsyncRAT starts with VBScript code that is executed from an ISO file. If you have your own exclusive approach to detecting cyber threats and strive to share your expertise with the world, you’re highly welcome to join our crowdsourcing initiative. Since AsyncRAT and 3LOSH in their older versions were spotted by threat intelligence specialists before, you can avail of our previous detections and see if there is anything else you should add to your threat hunting routine. The Sigma rule is mapped to the latest MITRE ATT&CK® version, addressing the Execution tactic and Command and Scripting Interpreter technique (T1059). This rule can be automatically converted to the following security solutions: Microsoft Sentinel, Chronicle Security, Elastic Stack, Splunk, Sumo Logic, ArcSight, QRadar, Humio, Microsoft Defender for Endpoint, Devo, FireEye, Carbon Black, LogPoint, Graylog, Regex Grep, Microsoft PowerShell, RSA NetWitness, Apache Kafka ksqlDB, Qualys, AWS OpenSearch. Suspicious 3LOSH (AsyncRAT) RAT Execution by Detection of Malicious Files (file_event) The novel Sigma-based detection rule written by our prolific Threat Bounty Developer Kyaw Pyiyt Htet recognizes possible 3LOSH execution based on the availability of certain malicious files: See our newest detections below which help to spot the latest activity of the 3LOSH crypter. Security analysts warn organizations that cyber-attacks may be leveraged by various threat actors, while the complexity of tools like the 3LOSH crypter is being continuously updated and improved. The purpose of this spike in the use of crypters is to increase the operational effectiveness of RAT and, as a result, exfiltrate sensitive data. Besides AsyncRAT, a number of other commodity malware strains can be distributed by the same operator. Recent cybersecurity research analyzes the latest version of 3LOSH that is being used by adversaries to evade detection on devices in corporate environments. Ongoing malware distribution campaigns spread AsyncRAT, including the 3LOSH crypter across public repositories.
