Over 12,000 WannaCry Variants Detected in the Wild
The State of Security
Security researchers have determined that over 12,000 variants of the WannaCry ransomware family are preying upon users in the wild.
Sophos attributed this rise of variants to threat actors taking the original 2017 WannaCry binary and modifying it to suit their needs. These versions have subsequently produced numerous infection attempts. In August 2019, for instance, researchers at the British security software and hardware company detected 4.3 million attempts by infected computers to spread the ransomware.
That’s not to say that all variants took equal part in generating these attacks. In its analysis of some 2,275 variants seen between September 2018 and December 2018, Sophos found that 10 variants in particular account for 3.4 million of the 5.1 million detections observed during that three-month period. (The top three made up 2.6 million.) By contrast, Sophos spotted 12,005 unique files just under 100 times, while the original 2017 WannaCry ransomware binary appeared just 40 times.
