Latest Message<\/th>\nTitle: Users are sometimes seeing erroneous threat alerts when clicking google.com links<\/p>\n

User impact: Users were sometimes seeing erroneous threat alerts when clicking google.com links.<\/p>\n

More info: Users received the SafeLinks block page or warning page at the time of click, and some admins may have received False positive click alerts.<\/p>\n

Admins may have received email notifications from Office365Alerts@microsoft.com<\/a> stating “A high-severity alert has been triggered on a potentially malicious URL that has been clicked”. <\/p>\n

The issue did not impact the delivery of email or Microsoft Teams chat messages.<\/p>\n

Final status: Through our investigation into a sample of affected messages, we’ve clarified and expanded the user impact and scope of impact, and we’ve amended this communication accordingly. We’ve also determined the affected URL links were blocked by our anti-spam functionality after being misclassified as malicious. We’ve confirmed the affected URL links are safe and added them to our allow list to remediate the impact.<\/p>\n

Scope of impact: This issue may have affected any user attempting to click some google.com URL links.<\/p>\n

Start time: Wednesday, September 18, 2024, at 4:48 PM UTC<\/p>\n

End time: Thursday, September 19, 2024, at 4:16 AM UTC<\/p>\n

Root cause: Our anti-spam functionality, which safeguards Exchange Online against potentially risky URLs, erroneously misclassified some Google domains as they followed a redirect pattern related to attacker abuse of the google.com platform.<\/p>\n

Next steps:
– We\u2019re continuing our analysis of the anti-spam functionality to help find ways to lower the false positive rate and ensure that legitimate URLs are not blocked.<\/p>\n

This is the final update for the event.<\/td>\n<\/tr>\n
