Iran targets M365 accounts with password-spraying attacks
Summary
Researchers have identified suspected Iran-linked threat actors employing password-spraying attacks against hundreds of organizations, predominantly Middle Eastern municipalities. The campaigns are believed to be linked to potential bomb-damage assessments following missile strikes.
IFF Assessment
Password-spraying attacks are a common and effective technique for attackers to gain unauthorized access to accounts and systems, representing a direct threat to defenders.
Defender Context
This campaign highlights the ongoing threat of sophisticated password-spraying attacks, especially targeting organizations in geopolitical hotspots. Defenders should ensure strong password policies, multi-factor authentication (MFA) is enforced across all M365 accounts, and monitor for unusual login patterns, particularly from geographic regions associated with the threat actor.
