Security News > 2021 > December > STOP Ransomware vaccine released to block encryption

German security software company G DATA has released a vaccine that will block STOP Ransomware from encrypting victims' files after infection.

While a decryptor was also released for STOP Ransomware in October 2019 by Emsisoft and Michael Gillespie to decrypt files encrypted by 148 variants for free, it no longer works with newer variants.

Since threat actors commonly bypass vaccines after they are released, this vaccine may stop working for future versions of this ransomware.

While other ransomware strains get the most media attention, STOP ransomware has constantly been behind the most significant slice of ID Ransomware submissions and support requests on BleepingComputer's forums in recent years.

Out of thousands of ID Ransomware submissions per day during high ransomware activity, anywhere between 60 and 70 % are STOP ransomware submissions.

The latter usually install a wide range of unwanted software onto a user's computer, and, more often than not, one of the programs installed is malware such as STOP Ransomware.
