German security software company G DATA has released a vaccine that will block STOP Ransomware from encrypting victims’ files after infection. The vaccine may cause your security software to believe your system is infected since it works by adding files the malware usually deploys on infected systems to trick the malware the device was already compromised. STOP ransomware is just your ordinary ransomware, which encrypts files, appends an extension, and drops a note asking for a ransom ranging from $500 to $1000. However, since threat actors commonly bypass vaccines after being released, this vaccine may stop working for future versions of this ransomware.”]
