Browlock

Browlock is an online security risk primarily associated with webpage hijacking and phishing scams. It is a type of browser lockdown, and it involves the redirection of web browsers to malicious websites without the user’s permission. Unlike other attacks, it does not require the user to click on a malicious link or download a malicious file – the user is simply redirected without being aware of it.

Browlock is enabled using malicious JavaScript code, often from pop-up windows, which open without the user’s permission and disable the back button and other browser controls. The malware then takes control of the page and the browser and can force the user to download and install unwanted programs, alter browser settings, or click on fraudulent advertisements.

Most Browlock attacks are conducted by sending users to a malicious website with a fraudulent URL, often disguised as a legitimate website. Once the user has been redirected, they are then presented with a warning or alert that their system may be at risk and must be fixed by downloading the malicious software. This malicious software is usually a fake antivirus program, but can also include malware, spyware, and other malicious programs.

To protect against Browlock, users should always make sure their browser and Operating System are up to date, and that they use a reputable antivirus program. They should also be wary of downloading files from untrusted sources and avoid clicking on suspicious links. Suspicious websites should also be avoided, as these websites may contain malicious code.
