Severity

High

Analysis Summary

Gamaredon APT (Advanced Persistent Threat) is a Russian-speaking cybercrime group that is known for its sophisticated and targeted attacks. This group has been active since at least 2013, and is believed to have ties to the Russian government.

The group is known for its use of custom malware and tools, such as the Gravis backdoor and the XAgent malware, which allow them to infiltrate and maintain control over targeted networks. They have been observed targeting a variety of organizations, including government agencies, military organizations, and critical infrastructure providers, in countries throughout Europe and the former Soviet Union.

Gamaredon APT is particularly known for its ability to steal sensitive information from its targets, including intellectual property, confidential documents, and login credentials. In some cases, the group has also been observed exfiltrating large amounts of data from its targets over extended periods of time.

It is important for organizations to be aware of the threat posed by Gamaredon APT and to implement appropriate security measures to protect against this group and other advanced persistent threats. This may include implementing strong security controls, regularly monitoring network activity for signs of compromise, and using advanced threat detection and response technologies.

Remediation

• Block all threat indicators at your respective controls.
• Search for Indicators of compromise (IOCs) in your environment utilizing your respective security controls
• Do not download documents attached in emails from unknown sources and strictly refrain from enabling macros when the source isn’t reliable.
• Enable antivirus and anti-malware software and update signature definitions in a timely manner. Using multi-layered protection is necessary to secure vulnerable assets
• Along with network and system hardening, code hardening should be implemented within the organization so that their websites and software are secure. Use testing tools to detect any vulnerabilities in the deployed codes.
