Swiss online shopping site Comparis filed a criminal complaint on Wednesday over a ransomware attack that blocked some of its computer systems, he said on Friday.
“As far as we know, most of the databases do not appear to be affected by the incident. Unfortunately, initial detailed analyzes suggest that the authors had access to some data relating to customers of sister company Credaris, including the systems are partly operated on the same server environment, ”he said.
Credaris is a financial brokerage company.
Comparis said its website – which allows consumers to compare prices for goods and services – is functioning normally again, but email and customer hotline access may still be limited because it works with specialists in cybersecurity on a full recovery.
He did not say whether the incident was linked to a ransomware attack centered on Florida-based information technology company Kaseya that scrambled the data of hundreds of small businesses around the world. REvil, a prolific cybercrime union linked to Russia, took credit for the breach.
Comparis did not pay a ransom to regain the functionality, a spokesperson said.
