An "automation bug" by Microsoft

Keep in mind that Microsof Defender ATP is the main business security solution of the Redmond brand.

According to ZDnet, Microsoft has said a few hours after this matter was discovered and users talked about it on social media, that the information Microsoft Defender ATP gives about Chrome files they are false positives due to "an automation error".

Suspicions towards the December 2020 attacks

If we take into account that in December 2020 there were different attacks on the supply chain of large software companies and the extent that they may have is still not well known, there are users on Twitter who feared that Chrome could really be infected.

When we talk about supply chain attacks we mean attackers compromise the security of a third party and with this they manage to infiltrate companies and clients in general who use their services. In December SolarWinds was the victim of a massive attack. The company was little known, but after its security problem it became known that its software was used by many of the largest companies in the world. Among others, Microsoft. However, now the creator of Windows says that this is all a bug and not a real security problem.
