JS.Fakeransom and JS Trojans Technical Description

Our team has already analyzed one ransomware that uses JavaScript to prevent the user from closing the page – the so-called MoneyPak Virus. The phishing site that initiated the attack presented a JavaScript loop that was set to lock the browser to the page.

For instance, when trying to visit a particular page after the suspicious site has been loaded, a warning is likely to show up. Such warning messages typically act as scareware and aim at frightening you. Such a message may contain information about an illegal action that you have recently performed online (such as visiting adult content pages), or installing pirated software. Interestingly enough, porn websites and pirated software are typically at fault for ‘infections’ of that type.warning-trojan

Using compromised websites to spread malicious code is neither new nor innovative. But it is definitely an effective technique in the realm of malware distribution.

JS.Fakeransom and similar threats may attempt to redirect the browser to another page. Some JS Trojans may employ websites compromised via SQL injection attacks or by using Blackhat SEO. Another way for such a threat to ‘infect’ the browser is if the page containing the malicious script is stored in the browser’s cache.

JS.Fakeransom Removal Methods

Pay attention to the following tips to improve your PC’s security:

  • Make sure to use additional firewall protection. Downloading a second firewall (like ZoneAlarm, for example) is an excellent solution for any potential intrusions.
  • Make sure that your programs have less administrative power over what they read and write on your computer. Make them prompt you admin access before starting.
  • Use stronger passwords. Stronger passwords (preferably ones that are not words) are harder to crack by several methods, including brute forcing since it includes pass lists with relevant words.
  • Turn off AutoPlay. This protects your computer from malicious executable files on USB sticks or other external memory carriers that are immediately inserted into it.
  • Disable File Sharing – it is recommended if you need file sharing between your computer to password protect it to restrict the threat only to yourself if infected.
  • Switch off any remote services – this can be devastating for business networks since it can cause a lot of damage on a massive scale.
  • Make sure always to update the critical security patches for your software and OS.
  • Employ a virus-scanning extension in your browser that will scan all the downloaded files on your computer.
  • Turn off any non-needed wireless services, like Infrared ports or Bluetooth – hackers love to use them to exploit devices. In case you use Bluetooth, make sure that you monitor all of the unauthorized devices that prompt you to pair with them and decline and investigate any suspicious ones.
  • Employ a powerful anti-malware solution to protect yourself from any future threats automatically.
