On August 2, 2022, an elite level threat actor "Kirti" from BreachForums posted a data breach package targeting Knoppix, a U.S.-based website that provides downloadable versions of GNU/Linux operating systems. The threat actor noted that the data package is from October 1, 2020 and includes 32,377 rows of user information. The data package was also circulated in deep web forums like Leakbase on August 14, 2022 by the threat actor "Chucky" and Raidforums on June 9, 2021. From the package published on BreachForums, ZeroFox extracted 32,370 email addresses, usernames, and hashed passwords.

Recommendations

• If not already enabled, turn on the compromised credentials rule for all relevant entities and ensure relevant emails are entered for those entities, or reach out to [email protected] for assistance
• If one of your entities receives an alert, ZeroFox recommends immediate password changes for the affected account
• Enable 2-factor authentication for all of your organizational accounts to help mitigate phishing and credential stuffing attacks
