Google has decided to take action against extensions that are considered malicious for Chrome. The company closed its siege mainly against plugins that inserted unwanted advertising on the websites visited by the victims.
It was concluded that more than a third of the extensions that inject ads are malware in a study conducted with the University of California. 192 cases were considered deceptive, affecting about 14 million people.
Since then, the company has taken steps to incorporate techniques that allow it to detect new extensions or updates that adopt similar practices.
The study shows that this practice is very common and affects many people, in various browsers, both on Windows and Mac. The survey shows that 5% of people who access Google sites had at least one malicious extension that injected advertisements into websites. Within this group, 50% have two and 33% have four or more.
It is important to note that the practice of injecting advertisements into web pages is not banned by Google, but there are some restrictions. For an extension of Chrome, for example, it is mandatory to alert the user and make clear what is going on. In addition, customers of the company’s advertising network are also not allowed to take advantage of unwanted software.
