→ File Name: WinSecurity.exe
Size: 241,152 KB
MD5: 45beca45fc84cfea06cfc50490a222ba

Researchers believe that this executable may be distributed along fake setups of programs downloaded from shady third-party locations. However, another scenario suggests that the file may be in an obfuscated form and could be distributed in an archive uploaded online or via spam e-mail messages. Either way, users are strongly advised to follow the usual security tips to protect themselves against ransomware in the future.
