dangerous malware spread in about thirty extensions, remove them quickly!

Edge and Chrome are victims of malware that can steal user data. Not surprisingly, the malware is able to determine the skill level of the user and will activate or not accordingly. The malware in question is spread through relatively popular extensions that sometimes promise to download YouTube videos and sometimes to send messages on Instagram.

Despite countless precautions by publishers, browsers are constantly being targeted by hackers of all persuasions. Especially when the attacked browser doesn’t have a heart, as with the Raccoon banking malware, hackers extensions found in different stores of these same browsers inject malicious code into their victims’ machines.

The ultimate threat is to both edge and Chrome, both have Chromium as their common source. Avast researchers have indeed discovered malware that spreads through relatively well-known extensions and often promises to help the user download videos from the Internet.

Malware learns user behavior before activating

Avast researchers have identified 28 Edge and Chrome extensions that are infected with a new type of malware. Malware is harmful in more ways than one. Once the machine is infected, the malware can sometimes show unwanted advertising (which is less bad), sometimes steal personal information (it’s more serious, you can imagine).

But one of the features of the malware is that it only activates after a few days. And during this time, he is not only super discreet, but also can analyze his victim’s behavior and skill level. For this, it uses its own history and determines whether it is a web developer or not.

Jan Voytesek, a security expert from Avast, explains that “the virus detects whether the user searches for one of their domains on Google or, for example, whether the user is a web developer. If so, then it won’t show any malicious activity in your browser. This avoids infecting people more experienced in web development, as they can more easily learn what extensions do behind the scenes.

More than 3 million computers are infected with malware hidden in Chrome and Edge extensions

Avast first discovered this threat in November 2020, but believes it may have been active for years. According to Avast’s estimation, this would be the case more than 3 million computers will be affected in this way.

About thirty extensions are concerned. Here is the full list. If some of them are duplicated, this is completely normal, because they can appear in one of the two stores (Google Chrome or Microsoft Edge), or they can be twice in each of them.
