Amazon SES abused in phishing campaigns, Kaspersky warns
🔔 Kaspersky reports an increase in phishing campaigns that abuse Amazon Simple Email Service (SES) to send authenticated-looking malicious messages that can bypass reputation-based filters. Attackers are harvesting exposed AWS access keys from public repositories and assets, automating secret discovery, permission checks, and mass email distribution. Because messages originate from a trusted service, SPF, DKIM, and DMARC checks and IP blocks are often ineffective, prompting Kaspersky to recommend stricter IAM controls, MFA, key rotation, and IP restrictions.
