A new ransomware strain known as “Zorab” has been discovered to be impersonating STOP Djvu ransomware and being distributed as a decryptor from the STOP Djvu family according to Michael Gillespie, founder of Ransomware ID service.
While this masquerading decryptor promises free decryption for Djvu infected files, Instead, the victims are infected with another ransomware making their situation worse off. Most of its attacks have been carried out through cracked software, shady websites, and adware bundles.
Kaspersky, a leading cybersecurity firm reports that Zorab is targeting consumers by magnifying the challenges currently being faced by victims of Djvu ransomware which encrypts and assign data extension depending on the version option including .djvus, .djvu, .uudjvu, .djvuu, and tfunde to altered files.
The developers of Zorab unleased a utility that purportedly decrypts these files, rather it encrypts them all over again using shady websites.
This fake decryptor extracts a copy of crab.exe which is another program (but does not belong to the GandCrab ransomware family) rooted within it as a data resource. Then writes crab.exe into your TEMP folder, then launches it before deleting itself.
Back in January 2019, STOP used adware installers disguised as cracks as a new method of distributing itself to unsuspecting users. According to a report from NakedSecurity, it was found that with over 600 submissions a day to the ID-Ransomware ransomware identification service, STOP ransomware is the most actively distributed ransomware over the past year.
