This group of Trojans is specially created to induce fear in your average inexperienced user by posing as a law enforcement notification service. ESG malware researchers have established an increasing trend in attacks by monitoring police ransomware threats such as Trojan:HTML/Browlock. Ransomware such as this one are the ones that we are most likely to see in near future. Also, known as Browlock, this type of ransomware may exhibit a pop-up screen on the user’s web browser, claiming that he or she has committed a crime and has to pay a ‘fine’ in order to evade legal consequences.

Trojan:HTML/Browlock -How Did I Get Infected With?

A very obvious cause of an infection is carelessness in most users. The Trojan may be distributed via malicious web links that may be opened via ad-supported search results, online pop-up ads, dangerous browser redirects and other. All of those are common for adware PUPs (Potentially Unwanted Programs) situated on your computer. Such unwanted apps come ’glued’ to third-party installers of various free programs provided by third-party sites. This is called bundling, and it is done solely to make money online. Also, the Trojan may come into existence in your machine by clicking on a malicious message, falsely advertised or sent by a virus on social networks, like Facebook, Twitter, and others.

Browlock trojan is reported also to do your regular ransomware activities, such as making modification in the victim’s OS to make sure they cannot escape the ransom message. This type of trojan varies in its methods of infection and is believed to modify its attack, depending on the victim’s location. ESG security analysts even report it to resemble every country’s law enforcement ministry in badges and language, depending on where your machine is situated. For example, if you are located in Spain, it may resemble Spanish police, and the message may be in Spanish.

Security researchers have managed to establish that one of the servers, connected with this trojan may be located in Saint Petersburg in Russia.
