The Phonzy Trojan is a banking trojan, which is a specific subtype of malware that has become increasingly common since the worldwide implementation of online banking. The Trojan is designed to collect your banking credentials, targeting the security mechanisms put in place by different banks to prevent such attacks.
Different banks have different security layers that the Trojan must circumvent to collect credentials. Online banking pages that do not have sufficient security measures are more vulnerable to the Trojan. In such cases, the threat simply copies the credentials entered by the victim and pastes them into a separate file. This file is then sent to the command server.
However, banks that care about the security of their customers force the threat to find a workaround. The specific Trojan:Script/Phonzy.A!ml variant, for example, is capable of changing the networking settings and browser configurations of the victim's computer. When the Trojan detects that the victim is using a secured banking page, it displays a phishing page to trick the victims into entering their credentials. This trick is achieved through the change of the HOSTS file. When the victims attempt to open the online banking website, they are redirected to a counterfeit page that appears to be legitimate but only contains a login window and a login error popup.
Getting Rid of the Phonzy Trojan may be Difficult
One especially potent aspect of the Phonzy Trojan is its ability to inject its code into legitimate programs, making it difficult to detect and remove. Furthermore, it can embed itself deeply into Web browsers such as Chrome, which poses a significant threat as a user could inadvertently become reinfected even after wiping their system and starting anew.
As such, when it comes to removing Trojan threats like Phonzy from a computer system, users should be meticulous in eliminating all traces of the malware.
Firstly, it's important to identify the Trojan that has infected the system. This can be done by running a comprehensive malware scan using reliable anti-malware software, which can help detect and isolate the Trojan.
Once the Trojan has been identified, users can take steps to remove it from their system. This typically involves using a professional security solution to quarantine or delete the infected files and clean up any associated Registry entries.
To prevent future Trojan infections, users should be cautious when downloading or installing software from untrusted sources. They also should avoid clicking on suspicious links or opening email attachments from unknown senders. Additionally, keeping anti-malware software up-to-date and regularly scanning the system for malware can help identify and remove any new threats before they can cause significant damage.
