Over 390M impacted by Russian social network breach

Infiltration of Zacks' active directory as domain admin enabled the theft of source code belonging to the company's primary website and 16 others, according to the threat actor, who has been peddling the exfiltrated account information, including full names, usernames, physical and email addresses, and phone numbers, for a small amount of cryptocurrency.

Such an intrusion was claimed to have resulted in the erasure of user accounts and the locking of administrative accounts, with Tooda hackers alleging the release of Doxbin admins' personal information and a blacklist of individuals who had paid for the data to be removed from the site while threatening to expose a user database with almost 136,000 username and email pairs.

Despite confirming that its China-based subsidiary Unimicron Technology (Shenzhen) Corp., had been disrupted by a ransomware intrusion on Jan. 30, Unimicron did not disclose being subjected to a data breach as it noted an ongoing investigation into the incident.
