Hackers could be actual jerks.

According to a brand new report from Bleeping Computer, the ransomware–which claims to decrypt recordsdata affected by the ‘STOP Djvu’ ransomware–really double-encrypts recordsdata, making victims’ issues even worse. The virus, referred to as “Zorab”, was found by Michael Gillespie, the creator of the ID Ransomware service.
Hmm, somebody launched a decryptor for #STOP #Djvu?
Oh wait… it is extra fucking #ransomware. Don’t belief something you discover on-line saying it will probably decrypt Djvu except it’s from ME. This is only one instance of the shaddy shit victims are falling for once they do not consider me. pic.twitter.com/eWjtB8UpJe

Zorab compounds present issues
Imagine: for years, encrypting ransomware has been a nightmare situation for unwitting pc customers. They click on the incorrect link, or open the incorrect e mail, and all of a sudden discover themselves in a state of affairs through which all of their recordsdata–their most valuable pictures, the novels they’ve been engaged on, their musical tasks, their work–is encrypted; the ransomware claims that solely method to decrypt it’s to pay an enormous charge.

Of course, there have been anti-malware instruments which have been developed to decrypt recordsdata with out paying exorbitant quantities of cash: that is precisely what this new malware is imitating. It claims to assist victims of ransomware decrypt their recordsdata without spending a dime, after which double-encrypts them.
Indeed, when the sufferer downloads opens one among these faux decryption “tools” and clicks on “Start Scan,” the software program extracts an executable file referred to as crab.exe–the Zorab ransomware itself. Once executed, the instrument will encrypt all recordsdata current on the system with a .ZRB extension.
Zorab additionally creates ransom notes named ‘–DECRYPT–ZORAB.txt.ZRB’ which can be current in every of the folders it encrypts; this be aware comprises directions on contact the ransomware operators for cost directions.
“We absolutely do not care about you and your deals, except getting benefits,” the notes learn.
STOP would be the most prolific ransomware on the market; Zorab goals to reap the benefits of this
In a manner, the creators of Zorab have been fairly intelligent: STOP Dvju is regarded as one of the crucial prolific–if not essentially the most prolific–items of ransomware on the books. Therefore, making a faux decryption instrument for STOP is a fast and simple method to unfold one other piece of ransomware.
While it hasn’t gotten as a lot media consideration as different items ransomware that targets high-net-worth people and organizations (equivalent to Maze, REvil, Netwalker, and DoppelPaymer), there are roughly 600 STOP ransomware submissions a day to the ID-Ransomware ransomware identification service.
Bleeping Computer described STOP as “the most actively distributed ransomware over the past year.”
The publication additionally mentioned that Zorab is at the moment being analyzed, and that victims mustn’t pay the ransoms which can be being demanded of them till it’s confirmed that there isn’t any method to exploit weaknesses in Zorab’s software program.
