On July 5, 2022, a reputed threat actor "Show_Stopper" from the deep web forum BreachForums posted a data leak package titled "US Debt Data- 2021 [34 MM]". The threat actor noted that the data dump is from the year 2021 which includes 34 Million users' information. From this package, ZeroFox extracted 33,928,630 email addresses. No passwords were found in this breach.

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
