Rewterz Threat Alert – MeterPreter Malware – Active IOCs

Severity

High

Analysis Summary

Meterpreter – a trojan-type program – enables attackers to take control of affected machines remotely. This malware injects itself into compromised processes rather than creating new ones. Meterpreter can be utilized to send and receive files, launch executable files, perform command shell operations, capture screenshots, and record keystrokes. The main objective of its distribution is either to generate revenue or infect devices with additional malware. Infected email attachments, malicious online advertisements, and social engineering are some of its distribution methods. Threat actors can infect victims’ systems with more malware, such as ransomware, by sending, receiving, and executing files using Meterpreter. Ransomware encrypts data, making it impossible for victims to use or access it unless they acquire decryption tools from the program’s creators. Identity theft, banking information, and password theft are the main impact of this trojan.

To protect against Meterpreter and other types of malware, it is essential to use a combination of security measures, including antivirus software, firewalls, intrusion detection and prevention systems, and security awareness training for employees. Additionally, keeping software and operating systems up to date with the latest patches and updates can help prevent vulnerabilities that hackers can exploit.

Remediation

• Block all threat indicators at your respective controls.
• Search for Indicators of compromise (IOCs) in your environment utilizing your respective security controls.
• Never trust or open links and attachments received from unknown sources/senders.
• Maintain cyber hygiene by updating your anti-virus software and implementing a patch management lifecycle.
• Patch and upgrade any platforms and software timely and make it into a standard security policy. Prioritize patching known exploited vulnerabilities and zero-days.
