Ransomware crew dumps stolen Optionis files online
2022-02-11 12:29

What appears to be stolen data belonging to customers of accounting conglomerate Optionis Group has surfaced on the dark web weeks after the firm confirmed intruders had broken into its systems.

The Vice Society ransomware gang dumped what appears to be thousands of files onto their dark web blog as downloadable links, as seen by The Register.

The vast cache was published shortly before Optionis Group, which also houses an umbrella company popular with tech contractors alongside its accounting businesses, emailed its tech contractor customers saying "Some data belonging to Optionis was copied from our system."

The dumping of contractors' data online is the usual step when a targeted organisation refuses to pay a ransom, in what experts have dubbed the "Double extortion" ransomware method.

Optionis previously claimed to have 13,000 contractors on its books.

Optionis did not respond to The Register's request for comment, but we will update this article when it does.
