The Play Ransomware Gang's Attack on Algotech

The Play ransomware gang has attacked Algotech. Algotech is an IT services provider headquartered in Prague, Czechia. It was founded in 1997 under the name Tservis97. Play posted Algotech to its data leak site on June 27th but has not provided any further details.

Background on Play Ransomware

Play ransomware (aka PlayCrypt) is a newer ransomware group that emerged in the summer of 2022 with high-profile attacks on the City of Oakland, Argentina's Judiciary, and German hotel chain H-Hotels. Play has similarities to Hive ransomware and is known to leverage tools like Cobalt Strike for post-compromise lateral movement and SystemBC RAT for persistence, as well as Mimikatz and living-off-the-land binaries (LOLBins) techniques. Play continued to increase attacks through the end of 2022 and into 2023.

Ransom Demands and Consequences

There is little information on how much Play demands for a ransom, but they have made good on their threats to leak the data of those who refuse payment.

Technical Tactics and Exploits

Play is an evolving RaaS platform known to exploit a known Exchange vulnerability (CVE-2022-41080 - patched by Microsoft in November of 2022) that allows them to leverage a second vulnerability with a ProxyNotShell exploit (CVE-2022-41082) even if a patch had been applied, which then allows the attackers to execute code on the systems remotely. Play leverages PowerTool to disable antivirus tools and security monitoring solutions.
