The Week in Ransomware – May 1st 2020

For the victims of the Shade Ransomware, otherwise known as Troldesh, this was an excellent week as the threat actors released over 750,000 decryption keys for their victims.

The Shade operators claimed to have shut down their operation at the end of 2019 and decided to release all of the master and individual decryption keys so that victims could recover their files for free.

Using these keys, Kaspersky has updated its ShadeDecryptor so that it can now decrypt any user who was encrypted by the Shade Ransomware in the past.

Other news this week includes a pharmaceutical company named ExecuPharm who filed a data breach notification after the actors behind the Clop Ransomware leaked stolen data

Other than that, it was just more releases of new variants of existing ransomware.

Coveware Q1 ransomware report

The Coveware ransomware marketplace report aggregates observed trends from enterprise ransomware incidents in Q1 of 2020. During the first quarter of 2020 ransomware threat actors took advantage of the economic and workplace disruption caused by the COVID-19 outbreak. Spam attacks related to the outbreak surged and seldom used ‘work-from-home’ network configurations led to increased ransomware attacks across the board. Some threat actor groups continued attacking healthcare organizations, while others refused to target them. Our report shows victim demographics and resolution metrics based on actual ransomware cases handled by the Coveware Incident Response team.
