French engineering research and consulting firm Altran Technologies disclosed this week that a Jan. 24 cyberattack impacted its operations in certain European countries.

In response to the incident, the company immediately shut down its IT network and all applications,” the company said in a press release issued on Monday.

Altran’s statement was short on specifics, but a report from Bleeping Computer today says that the company appears to have fallen victim to a ransomware program known as LockerGoga. The report cited a tweet from a computer researcher with the Twitter handle @xvxsh4d0w, which suggests that a particular malware sample found on VirusTotal was responsible for the attack.

“We have mobilized leading global third-party technical experts and forensics, and the investigation we have conducted with them has not identified any stolen data nor instances of a propagation of the incident to our clients,” the release stated. “Our recovery plan is unfolding as expected and our technical teams are fully mobilized.”
