An advanced persistent threat (APT) linked to Iran’s Ministry of Intelligence and Security (MOIS) provides initial access to Iranian state hacking groups, targeting valuable networks across sectors like government, media, and telecommunications. UNC1860 deploys a range of custom malware tools and backdoors to establish a foothold, staying undetected by focusing on inbound traffic and utilizing encrypted communication. Focusing on vetting incoming network traffic is essential for detecting UNC1860’s activity.
Based on the meeting notes, the key takeaways are:
1. A sophisticated advanced persistent threat (APT) group known as UNC1860, tied to Iran’s Ministry of Intelligence and Security (MOIS), focuses on gaining initial access to valuable networks across high-value sectors such as government, media, academia, critical infrastructure, and telecommunications.
2. UNC1860 uses a series of increasingly sophisticated backdoors and custom malware tools to establish a foothold in targeted organizations’ networks, collaborating with other Iranian nation-state actors for attacks on targets in Iraq, Saudi Arabia, and Qatar.
3. The group’s implants are entirely passive, utilizing HTTPS-encrypted traffic, and do not send any information out from target networks, making it challenging to detect through outbound communications. Instead, they focus on inbound requests, which can come from stealthy sources including VPN nodes and other victims of prior attacks.
4. To avoid detection, UNC1860’s implants use undocumented tools of HTTP.sys, reverse-engineered by the group, to set up listeners for incoming requests, and only need to send one command at any random point in time to activate the backdoor.
5. Organizations are advised to focus on vetting incoming network traffic to detect UNC1860’s activity, as traditional detection methods may not be sufficient due to the group’s sophisticated approach.
These takeaways provide a clear understanding of UNC1860’s tactics and emphasize the importance of vigilance in detecting and mitigating potential threats from this APT group.
