On May 29, 2020, Unit 42 researchers discovered a new variant of a hybrid cryptojacking malware from numerous incidents of CVE-2019-9081 exploitation in the wild. A closer look revealed the malware, which we’ve dubbed “Lucifer”, is capable of conducting DDoS attacks and well-equipped with all kinds of exploits against vulnerable Windows hosts. The first wave of the campaign stopped on June 10, 2020. The attacker then resumed their campaign on June 11, 2020, spreading an upgraded version of the malware and wreaking havoc. The sample was compiled on Thursday, June 11, 2020 10:39:47 PM UTC and caught by Palo Alto Networks Next-Generation Firewall. At the time of writing, the campaign’s still ongoing.
Lucifer is quite powerful in its capabilities. Not only is it capable of dropping XMRig for cryptojacking Monero, it’s also capable of command and control (C2) operation and self-propagation through the exploitation of multiple vulnerabilities and credential brute-forcing. Additionally, it drops and runs EternalBlue, EternalRomance, and DoublePulsar backdoor against vulnerable targets for intranet infections.
