The Week in Ransomware – March 18th 2022 – Targeting the auto industry

This week, the automotive industry has been under attack, with numerous companies exhibiting signs of breaches or ransomware activity.

It started with a ransomware attack on Denso, the world’s largest automotive components manufacturer, who was hit by the new Pandora ransomware operation. Pandora is believed to be a rebrand of the Root ransomware operation.

Dragos Inc. later reported increased Emotet activity targeting the automotive industry, which usually leads to Conti ransomware attacks.

BleepingComputer has also been tracking a ransomware attack this week against Snap-On, a manufacturer of tools for the transportation industry.

We first learned of the attack after one of their subsidiaries, Mitchell 1, suffered an outage of their automotive repair software that a source told us was caused by a ransomware attack.

Yesterday, Conti claimed responsibility for the attack on Snap-on.

Good news this week is the release of a decryptor for the Diavol ransomware, an operation run by the TrickBot Group.
