According to Google Project Zero, a team of security analysts at the search giant, eleven zero-day vulnerabilities have been discovered on the network and are being used by a team of professional hackers to infect Windows, Android and iOS devices. It is worth noting that cybercriminals have been using their hacking methods since February 2020 to the present day – at the moment, the developers of operating systems have not yet created effective enough protection to prevent malicious code from interfering with the operation of devices.
In addition, Maddie Stone, an employee of the Google Project Zero team, described the mechanism used by the hacker team in some detail. She said that attackers use malicious code that is embedded in various websites, thereby infecting them. Further, a compromised site, which a person visits quite often, redirects the user to a special infrastructure that installs the exploit on the device, gaining extended access rights. At the same time, the malicious code and infrastructure created by a group of hackers are quite advanced – the system automatically detects the type of gadget, its operating system and browser version in order to introduce the “malware”.
For example, on desktop computers running the Windows 10 operating system, hackers’ software reprograms Google Chrome, on iOS, malicious code allows them to gain privileges through Safari, and on Android, the Samsung or Google Chrome browser is used to gain access to a higher level. But, however, there are a number of restrictions – only devices on iOS 11-13 and Android 10 can be hacked by this method. Representatives of Google Project Zero said that although the vulnerability was still used by hackers, on Android 11 and iOS 14 cases of successful attacks on devices were not recorded It was. However, it can only be a matter of time.
