The vulnerability stems from WinRAR using insecure connections to access message content from the server side through Notifer Windows. Therefore, an attacker can penetrate this connection to install malicious code on the victim's machine to gain control. Moreover, hackers can also attack multiple targets at the same time to create large-scale targeted attack campaigns.

WinRAR has released update 6.02 to patch CVE-2021-35052.

For users, you can keep yourself safe by updating WinRAR. Alternatively, you can also completely remove this software from your computer and replace it with a better file compression and decompression software, such as 7zip.
