EnigmaSoft Threat Scorecard
EnigmaSoft Threat Scorecards are assessment reports for different malware threats which have been collected and analyzed by our research team. EnigmaSoft Threat Scorecards evaluate and rank threats using several metrics including real-world and potential risk factors, trends, frequency, prevalence, and persistence. EnigmaSoft Threat Scorecards are updated regularly based on our research data and metrics and are useful for a wide range of computer users, from end users seeking solutions to remove malware from their systems to security experts analyzing threats.
EnigmaSoft Threat Scorecards display a variety of useful information, including:
Ranking: The ranking of a particular threat in EnigmaSoft’s Threat Database.
Severity Level: The determined severity level of an object, represented numerically, based on our risk modeling process and research, as explained in our Threat Assessment Criteria.
Infected Computers: The number of confirmed and suspected cases of a particular threat detected on infected computers as reported by SpyHunter.

JS/ProxyChanger.CW is a detection name used by cyber security specialists to specify a Trojan written in JavaScript and used to alter the proxy settings on remote systems. JS/ProxyChanger.CW is a Trojan that uses an automatic configuration script to force users into using a particular proxy. The result is that the user's network traffic is routed to a server operated by a threat actor. Consequently, the data you sent and receive can be recorded, analyzed, modified and decrypted by a third-party. The operations of the JS/ProxyChanger.CW Trojan require an automatic configuration script that is packed as 'wpad.dat.' The Windows OS generates 'wpad.dat' when you choose the 'Detect Settings Automatically' option in the Local Area Network (LAN) Settings panel. However, the JS/ProxyChanger.CW Trojan is programmed to connect to a remote host and download a foreign Web Proxy Auto-Discovery Protocol (wpad.dat) file and reroute your traffic to servers under the control of a third-party.
JS/ProxyChanger.CW works very similarly to browser hijacking add-ons and threats like AutoConfigUrl and Hijack.AutoconfigURL. PC security researchers report that the JS/ProxyChanger.CW Trojan is used in attacks on regular computer users and members of corporate networks alike. JS/ProxyChanger.CW can be introduced to computers via tools like RIG and Infinity that exploit vulnerabilities in plug-ins like Adobe Flash and Java. Also, free program bundles offered on untrusted pages may include JS/ProxyChanger.CW and make modifications to the LAN settings of the user as part of an 'Internet optimization.' The JS/ProxyChanger.CW threat has the potential to redirect users to phishing pages and allow third parties to deploy Man-in-the-Middle (MITM) attacks. PC users that suspect JS/ProxyChanger.CW hijacked their Internet configuration may want to scan their OSes with a trustworthy anti-malware scanner.
