The Rakhni Trojan (Trojan-Ransom.Win32.Rakhni), first spotted in 2013, is now giving bad actors the ability to infect victims either with a ransomware cryptor or a miner. The malware, which has mostly been infecting victims in Russia, is first distributed via email spam campaigns. The downloader (an executable file written in Delphi) displays a message box with an error text purporting to be from Adobe throwing victims off track from suspecting they have been infected.
