Infosecurity Magazine
Actively Exploited
A recent report from Proofpoint reveals a rise in phishing attacks that take advantage of Microsoft's OAuth device code flow. These campaigns target Microsoft 365 users, tricking them into providing access to their accounts through fake sign-in prompts. The attacks exploit the trust users place in the OAuth process, which is designed to facilitate secure authentication. As a result, individuals and organizations using Microsoft 365 could be at risk of unauthorized access to sensitive information. This surge in phishing attempts underscores the need for heightened awareness and vigilance among users to avoid falling victim to these scams.
Impact: Microsoft 365
Remediation: Users should be cautious of unsolicited sign-in requests and verify the legitimacy of prompts before entering credentials. Implementing multi-factor authentication can also help mitigate risks.
