The Microsoft 365 Defender Threat Intelligence team is back with another massive report detailing its in-depth findings on the latest threat to computer owners’ security. However, this time, Windows 11 users can stop sweating and put the towel down, since the heat is on Mac fans. Microsoft’s report details a sophisticated trojan that’s been steadily evolving since September 2020 to more effectively ruin Mac owners’ days.
Microsoft has dubbed the trojan “UpdateAgent” and outlined its capabilities, which include pretending to be safe, harmless software and, worse, using a Mac’s own specificities for nefarious purposes. If you thought Macs were bulletproof in terms of being able to safeguard you and only run trusted apps, UpdateAgent has bad news to share. And, worse, it’s capable of cleaning its tracks once it’s done ravaging your machine. Here’s a taste of its evolutionary timeline, as stated by Microsoft:
Since its first appearance in September 2020, the malware displayed an increasing progression of sophisticated capabilities, and while the latest two variants were sporting much more refined behavior compared with earlier versions, they show signs that the malware is still in the development stage and more updates are likely to come. The latest campaign saw the malware installing the evasive and persistent Adload adware, but UpdateAgent’s ability to gain access to a device can theoretically be further leveraged to fetch other, potentially more dangerous payloads.
You can check out Microsoft’s security blog post for the full scoop. Just know that so long as UpdateAgent variants roam the plains, Mac owners should use Microsoft Edge for additional protection (yes, the blog ultimately builds toward a Microsoft product plug, though there’s additional guidance in the full post). This isn’t the first time Microsoft’s warned Apple fans of danger, and it likely won’t be the last.

Microsoft will begin testing experimental Windows 11 features with Insiders
Microsoft has today announced that it’s changing up the way in which it flights preview builds of Windows 11 to Insiders registered in the Dev or Beta Channels. Going forward, both channels are to be considered the “active development branch,” but for different kinds of feature testing.
