Analysis Summary
Windows utility developer IObit was recently hacked to perform a widespread attack to distribute the strange DeroHE ransomware to its forum members. IObit is a software developer known for Windows system optimization and anti-malware programs, such as Advanced SystemCare. Over the weekend, IObit forum members began receiving emails claiming to be from IObit stating that they are entitled to a free 1-year license to their software as a special perk of being a forum member.
Included in the email is a ‘GET IT NOW’ link that redirects to hxxps[:]//forums.iobit.com/promo.html. This page no longer exists, but at the time of the attack, it was distributing a file at hxxps[:]//forums.iobit.com/free-iobit-license-promo.zip. This zip file contains digitally signed files from the legitimate IObit License Manager program, but with the IObitUnlocker.dll replaced with an unsigned malicious version. When IObit License Manager.exe is executed, the malicious IObitUnlocker.dll will be executed to install the DeroHE ransomware to C:\Program Files (x86)\IObit\iobit.dll and execute it. As most executables are signed with IOBit’s certificate, and the zip file was hosted on their site, users installed the ransomware thinking it was a legitimate promotion.
