Many of the main computer security threats come through the browser. After all, it is the tool we use to enter websites, services and platforms of all kinds on the web. Today we are echoing a new malware campaign that attacks four of the main browsers globally. It affects Google Chrome, Mozilla Firefox, Edge, and Yandex. The first two are some of the most used in Spain, with the Google browser at the helm.
A malware campaign attacks Chrome and Firefox
This new malware campaign is bombarding browsers and putting users’ security and privacy at risk. This affects Google Chrome and Firefox, which are two of the most important browsers in Spain, but also Edge and Yandex.
One of the problems with this malware campaign is that it adds malicious extensions to the browser. We already know that the add-ons are very varied and we can install them in different browsers to have functions and features that are not present in this type of software as standard. However, these extensions that it adds are malicious and can pose a significant problem.
They have called this malware campaign Adrozek . It has 159 unique domains, each of which hosts an average of 17,300 unique URLs, which in turn have 15,300 malware samples.
This campaign is not new, since it has been active for several months. According to security researchers, at peak times they could infect 30,000 devices every day.
The ultimate goal of this campaign is to inject ads into search results. In this way the attackers can obtain income through the affiliates. But they can also change your security settings and take more serious malicious actions.
Keep in mind that we are not facing the first threat of this type that takes advantage of affiliate programs . After all, hackers are constantly looking for a way to profit, to obtain an economic benefit, at the expense of Internet users. This means that they can modify the advertisements for their own interest, for example.
Ad injection is not something that necessarily affects our security, since they do not usually infect computers with malware, but simply change or add advertisements when searching or opening pages.
Security researchers indicate that this campaign uses more sophisticated methods to try to evade antivirus and achieve its ultimate goal. This means that we must protect our equipment at all times and not make mistakes.
Something fundamental is going to be common sense . It is vital to only install extensions from official sources and make sure they are updated to the latest version. Adding outdated software can be a very significant issue that puts our privacy and security at risk.
We must also know at all times what add-ons are installed in our browser and what their real function is. In this way we can detect possible extensions that have been added without our knowledge.
