The provided information relates to OSINT (Open Source Intelligence) indicators of compromise (IOCs) associated with the Andromeda malware infrastructure, specifically linked to the domain restlesz.su. Andromeda is a well-known modular botnet malware family that has been active for several years, primarily used for distributing other malware, stealing information, and enabling remote control of infected systems. The domain restlesz.su appears to be part of the command and control (C2) infrastructure used by Andromeda operators to manage infected hosts. However, the data provided is limited, with no specific technical details, affected software versions, or exploit mechanisms described. The threat level is noted as low, and there are no known active exploits in the wild tied to this domain at the time of reporting. The lack of detailed indicators and technical specifics suggests this is primarily an intelligence report highlighting the association of certain IOCs with the Andromeda botnet rather than a direct vulnerability or active exploit. The information is dated from 2014, indicating that this is historical intelligence rather than a current emerging threat. Overall, this report serves as a reference for security teams to recognize and monitor the restlesz.su domain in network traffic or logs as part of broader Andromeda-related threat detection efforts.

For European organizations, the impact of this threat is generally low given the age of the information and the absence of active exploits linked to the restlesz.su domain. However, if systems are infected by Andromeda malware, they could be used as part of a botnet for malicious activities such as data theft, credential harvesting, or as a platform for launching further attacks. The presence of Andromeda-related infrastructure in network traffic could indicate compromised endpoints, which may lead to confidentiality breaches or unauthorized access. European organizations with legacy systems or insufficient endpoint protection might be at risk if remnants of this malware persist. Additionally, sectors with high-value data or critical infrastructure could face indirect risks if infected machines are leveraged in broader attack campaigns. Nonetheless, the immediate threat level is low, and the primary impact is related to detection and remediation of infections rather than a new vulnerability or exploit.

1. Implement network monitoring and intrusion detection systems (IDS) to identify and block traffic to known malicious domains such as restlesz.su. 2. Maintain updated endpoint protection solutions capable of detecting and removing Andromeda malware variants. 3. Conduct regular threat hunting exercises focusing on historical IOCs related to Andromeda to identify any lingering infections. 4. Educate users on phishing and social engineering tactics commonly used to distribute malware like Andromeda. 5. Apply strict egress filtering to prevent infected hosts from communicating with C2 servers. 6. Review and update incident response plans to include procedures for botnet infection detection and remediation. 7. Collaborate with threat intelligence sharing communities to stay informed about any resurgence or new variants of Andromeda.
