UK-based vehicle tracking solutions provider Microlise confirmed last week that data was stolen from its systems during an October cyberattack.

Disclosed on October 31, the incident resulted in a large portion of Microlise’s network being disrupted, which impacted tracking systems and panic alarms in the prison vans and courier vehicles of at least two operators, namely DHL and Serco.

One week later, the company said it was already bringing some of the affected services online, but noted that some employee data was likely compromised during the attack.

Last week, Microlise notified the London Stock Exchange that the restoration process was essentially completed, confirming the theft of data from its systems.

“The company can now confirm that the vast majority of customer systems are back online, with some remaining customers conducting their own security verifications before enabling users. The company would like to reiterate that no customer systems data was compromised,” Microlise said.

The company said it has notified international authorities that corporate data was stolen from its headquarters, without providing further details on the matter.

SecurityWeek has emailed Microlise for additional information on the cyberattack and will update this article as soon as a reply arrives.  

Two days after Microlise’s updated notice to the London Stock Exchange, the SafePay ransomware group listed the company on its Tor-based leak site, claiming the theft of 1.2 terabytes of data.

A relatively obscure gang, SafePay uses LockBit-based ransomware in attacks and engages in double-extortion tactics, threatening to release data allegedly stolen from its victims.

To date, the group has claimed responsibility for over 20 intrusions and has made the data of some of its alleged victims available publicly.
