STOP Ransomware Decryptor Released for 148 Variants
Emsisoft and security researcher Michael Gillespie have released a decryptor for 148 version of the STOP ransomware family. However, victims who were targeted after August of this year will not be able to regain access to their files with this decryptor.
A recent report by Emsisoft listed STOP as the most common ransomware in Q2 and Q3 of this year, accounting for 56% of attacks. STOP is often masqueraded as an app for obtaining paid software for free. It mostly spreads via torrent sites and therefore targets individual users rather than organizations via generic campaigns.
