The Week in Ransomware – January 15th 2021


It has been another quiet week for ransomware, though we did have some interesting stories come out this week.

By far, the most interesting is the news about ChastityLocker – ransomware that exploits vulnerabilities in men’s chastity belts (not joking) so that they can’t unlock them.

Other interesting news is Intel’s announcement that their new vPro chips will have built-in hardware ransomware detection and BitDefender released a decryptor for the DarkSide ransomware.

Unfortunately, after the decryptor was released, the DarkSide operation announced that they fixed the weakness allowing the decryptor to work.

Contributors and those who provided new ransomware information and stories this week include: @struppigel, @Ionut_Ilascu, @VK_Intel, @BleepinComputer, @FourOctets, @serghei, @Seifreed, @malwrhunterteam, @demonslay335, @DanielGallagher, @fwosar, @malwareforme, @jorntvdw, @PolarToffee, @LawrenceAbrams, @Telekom_group, @LukasStefanko, @GrujaRS, @Bitdefender, @vxunderground, @JakubKroustek, @M_Shahpasandi, @Kangxiaopao, @ExtendedRaavan, and @Amigo_A_.
