Persistence is achieved through dual mechanisms, including registry run keys and scheduled tasks named RuntimeBroker or Lightshot, ensuring the malware reactivates across reboots and runs every three minutes. Users should regularly inspect registry entries and task schedules for unauthorized changes, removing any suspicious configurations to disrupt this cycle.
Bypassing Antivirus Through Exclusion Tactics
A particularly insidious feature is the “Defender Excluder” script, which adds critical directories to Windows Defender’s exclusion list, shielding the malware from scans. This tactic highlights the importance of reviewing antivirus settings to ensure no unauthorized exclusions exist. Restoring default security configurations and using secondary scanning tools can help uncover hidden threats that evade primary defenses.
Phase 4 – Resilient C2 Communication for Control and Exfiltration
Step 4: Monitor Network Activity for Anomalous Traffic
Communication with the C2 infrastructure is both stealthy and resilient, utilizing lightweight UDP packets (approximately 45 bytes) to IPs like 104.21.80.1 for keep-alive signals, alongside encrypted HTTPS connections to domains such as salat.cn/salat for data transfer. Network monitoring tools can assist in identifying unusual outbound traffic patterns, flagging potential C2 interactions for further investigation.
Redundancy in Communication for Uninterrupted Control
If primary domains are blocked, fallback mechanisms via JavaScript routines retrieve alternative domains from a file like sniff_domain_list.txt, ensuring continuous connectivity. This redundancy underscores the need for comprehensive network security that blocks not only known malicious domains but also monitors for suspicious fallback behaviors. Deploying firewalls with deep packet inspection capabilities can provide an additional layer of defense.
