Librarian Ghouls, an APT group targeting entities in Russia and the CIS, has been conducting a campaign involving targeted phishing emails with malicious archives. The attackers use legitimate third-party software and scripts to establish remote access, steal credentials, and deploy an XMRig crypto miner. Their tactics include disabling security measures, scheduling tasks to cover their tracks, and exfiltrating sensitive data. The campaign primarily affects industrial enterprises and engineering schools in Russia, with some victims in Belarus and Kazakhstan. The group continues to refine its methods, focusing on data exfiltration, remote access, and email account compromise through phishing sites.

A recent incident response case in Brazil revealed a Perl-based crypto mining botnet called Outlaw, also known as Dota, targeting Linux environments. The threat actor exploits weak SSH credentials, downloads malicious scripts, and deploys an XMRig miner for Monero cryptocurrency. The botnet includes an IRC-based client that acts as a backdoor, allowing for various malicious activities. Victims have been identified mainly in the United States, with additional targets in Germany, Italy, Thailand, Singapore, Taiwan, Canada, and Brazil. The article provides detailed analysis of the malware's components, persistence mechanisms, and evasion techniques. Recommendations for system administrators include hardening SSH configurations and implementing additional security measures to mitigate the risk of compromise.
