Microsoft alerts to new wave of attacks targeting Microsoft 365 accounts

SAPO Notícias13 September 2026 at 19:30

Microsoft issued an urgent alert about a new wave of attacks targeting Microsoft 365 accounts. The threat specifically targets the corporate ecosystem, seeking to compromise organizations through sophisticated methods.

The attacks in question use techniques that subvert existing security tools on the platform. This approach allows attackers to bypass defenses that would normally be effective against simpler threats.

Organizations using Microsoft 365 are directly affected by this campaign. The nature of the attacks suggests a high level of sophistication, capable of exploiting vulnerabilities in the integrated protection features of the service.

Why this matters

Organizations using Microsoft 365 face an increased risk of sophisticated attacks that exploit legitimate tools. This alert is relevant for system administrators and IT managers who need to implement additional protection measures in their digital infrastructures.
