Today's hackers have advanced to the point that they can hide nasty malware behind seemingly legitimate software. This evil malware will breach your computer, block your access to files/programs and possibly force you to buy a new machine. Such malware is known as a Trojan virus. Trojans are malicious programs that infect computers in a covert manner similar to how the Greeks used a large fake horse to attack the Trojans inside their own city. In modern times, as soon as the target downloads the phony item in question, the Trojan wreaks havoc. Here’s a look from IT support experts in Philadelphia at what you need to know about Trojan viruses:
Why Trojan Viruses are So Unique
Trojans are incredibly dangerous compared to other types of malware and viruses due to the fact that they are intentionally concealed. Once delivered, the Trojan can function like other types of malware. The Trojan can do anything from record keystrokes to encrypting/corrupting data, providing hackers with remote access to systems and plenty more. Trojans move from one computer to the next in the same manner, disguised as harmless files. The goal is for the target to download and open the virus.
As soon as the Trojan infiltrates the system, it will replicate on its own. This is precisely why Trojans are so dangerous in the context of corporate networks. If the virus finds a way around the firewall, it will spread unless additional barriers are put in place for detection. Malware protection positioned at endpoints will certainly prove helpful in identifying and quarantining the infection. Our IT support company in Philadelphia is here to help with such malware protection and additional strategies to prevent a debilitating Trojan attack.
Trojans are separated into three basic categories:
- The backdoor variety
- The banking type
As soon as a backdoor Trojan is downloaded and executed, hackers can access and even control a target's computer in a remote fashion. There are numerous reasons as to why a malevolent individual will try to find a way in through a backdoor. This covert method makes it possible to snoop within the system for important data. Backdoor entry also helps with the modification of files and monitoring the device while it is in use. If such a Trojan is not identified and the weakness that allowed for it to be downloaded is not patched, an attack will be possible at any time.
Trojans of the “downloader” variety serve as a transportation vehicle for additional malware. As soon as the Trojan is opened and executed, it will download additional malware right onto the machine. Such malware can range from keyloggers to ransomware and cryptocurrency miners. The banking variety narrows in on users' financial information, including transactions. Upon download, a banking Trojan will seek out cookies relating to financial services the computer has stored when the target visited the bank's website. The Trojan uses this data to send the user to a phony banking site where the login credentials are stolen.
