The Week in Ransomware – May 11th 2018

Ransomware is definitely slowing down with most big attacks being targeted over RDP. With that said, we do see a steady stream of smaller ransomware infections that continue to be created, even if they never have much impact at all.

The biggest news over the past two weeks has been the continued releases of Gandcrab and some interesting writups about BlackHeart and SynAck.

Contributors and those who provided new ransomware information and stories this week include: @fwosar, @FourOctets, @jorntvdw, @malwareforme, @demonslay335, @PolarToffee, @hexwaxwing, @struppigel, @BleepinComputer, @LawrenceAbrams, @campuscodi, @Seifreed, @DanielGallagher, @malwrhunterteam, @FBI, @MarceloRivero@jeromesegura@zsawei@kaspersky, @antonivanovm, @TrendLabs@SophosLabs, @leotpsc, @bartblaze, and @Amigo_A_.

TeamViewer, a tool with more than 200 million users, was abused as by a previous ransomware that used the victim’s connections as a distribution method.
