Details

A threat actor "Perseus" who is currently banned on the Russian languague forum XSS has posted a combolist package titled "Crypto_529k". ZeroFox extracted 568,849 email addresses from more that 100 uniquie email domains and identified passwords in human readable format.

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
