Cybersecurity News: Microsoft 365 outage, China’s cyber campaign fallout, Fake IT worker scheme

Microsoft 365 outage update

If you were wondering whether Microsoft’s outages on Monday should have been your cue to start your Thanksgiving vacation early, you weren’t alone. Microsoft addressed widespread Microsoft 365 outages affecting services like Exchange Online, Microsoft Teams, SharePoint Online, and Outlook. The issue, caused by a “recent change,” has led to difficulties accessing these platforms and performing certain actions within Microsoft Fabric and Defender for Office 365. Microsoft deployed a fix to the affected environments, initiated manual restarts on impacted systems, and, as of this recording, is monitoring progress. While this follows a major outage in July caused by a DDoS attack, Microsoft has not attributed the current incident to any malicious activity.

“Hair on Fire” over China’s cyber campaign

The Biden administration met with telecom executives to discuss the impact of China’s cyber espionage campaign targeting U.S. telecommunications networks, which may require a large-scale rebuild of infrastructure.Senator Mark Warner, chair of the Senate Intelligence Committee, has raised alarms over China’s persistent cyberattacks on U.S. telecommunications networks, describing their severity as far exceeding previous incidents. He said China’s actions make Russia-linked incidents like the SolarWinds hack and Colonial Pipeline attack look like “child’s play.” Warner highlighted that attackers exploited wiretapping capabilities and stole extensive data from U.S. networks, while the administration’s meeting emphasized sharing intelligence on the ongoing threat. China denies these claims, but U.S. officials have described the activity as significant and unresolved.

SMS blaster busted

One hundred thousand spam texts an hour—talk about a nightmare. Thai police say they’ve arrested a van driver in Bangkok for operating an SMS blaster device capable of sending that many spam messages, targeting nearly one million people in just three days. The messages, impersonating Thailand’s largest mobile phone operator, AIS, lured victims to a phishing site with lines like “Redeem your gift now” or “Your points are about to expire” to steal credit card details for unauthorized transactions. The scam was orchestrated by a fraud gang coordinating via Telegram, with additional members of the group still at large.
