Researchers found a large botnet, with over 130,000 compromised devices, executing password spraying attacks on Microsoft 365 accounts. Unlike previous methods, this campaign leverages non-interactive sign-ins to bypass typical alert systems, making detection difficult. Cybersecurity experts, like Boris Cipot, point out that this evolution in attack tactics allows for stealthier exploitation of security gaps. They recommend implementing geo-location access policies, device compliance checks, and multi-factor authentication (MFA) to mitigate risks and enhance security practices against such advanced threats.
Cyber experts highlight that the new botnet employs non-interactive sign-ins, making it easier for attackers to evade conventional detection methods in password spraying campaigns.
Boris Cipot emphasizes that the latest tactics show a significant evolution in password spraying, utilizing less detectable methods by exploiting gaps in organizations' authentication monitoring.
