JS/ProxyChanger.BW is a proxy Trojan horse. The nefarious program takes over the targeted system and turns it into a botnet. JS/ProxyChanger.BW uses computers to spread malware. Your machine will mediate the install of infections onto other devices. The insidious program can install spyware to your computer, as well. Trojans often function as a host for ransomware and keyloggers. There is a risk for your personal files and your private data.

How does JS/ProxyChanger.BW pose a threat to my security?

The Trojan penetrates the operating system and rearranges its internal settings. JS/ProxyChanger.BW can make malicious registry entries, change the values of the presets, bring down the security settings and drop compromised files onto the hard drive. The processes of JS/ProxyChanger.BW are done on the background. You may not take notice of them. The best sign about the presence of the malevolent program is the change in the system’s performance speed. Your computer will become sluggish. Upon noticing a disturbance in the machine’s functionality, check your user settings. The key points to look up are the Windows firewall and the web browser. The Trojan can install rogue extensions and disable the ad-blocking software. The virus makes these changes to prevent the OS from prohibiting its tasks.

The main purpose of JS/ProxyChanger.BW is to spread malware. The covert program uses computers to create a botnet for distributing viruses. Hackers can access your machine from their servers and use the Trojan to transfer infections to remote devices. The renegade developers can transmit spyware to the host device, as well. Trojans spread different types of infections. Ransomware and keyloggers are the most common clients.

Ransomware, also known as win-lockers, are file encryption software. They use an algorithm to lock files. The victim is required to pay a ransom for the decryption key or software. This type of infection targets most file types, leaving only the essential system data intact. Keyloggers monitor users’ online sessions, collecting information from the web browser. They can record the browsing history, tracking cookies, keystrokes, IP address, geographic location, zip code, demographic details, physical address, date of birth, email, telephone number, fax, user names, passwords, PIN codes and other personal and financial data. The gathered information can be used to break into your accounts. The hackers behind JS/ProxyChanger.BW have two alternatives to choose from. They can either deploy an attack or trade your data on darknet markets.

This process is initiated when visiting a corrupted website or clicking on a compromised link. Our advice is to do your research on your sources.

The other propagation vector JS/ProxyChanger.BW makes use of is spam emails. The covert program hides behind an attachment. This technique enables the transferal in an equally simple manner. When the file is accessed, the Trojan gets downloaded and installed through a background process. You need to handle your messages with the utmost caution.
