What is a Trojan And How to Protect Against It?

The tale of the Trojan war is a source of fascination over the centuries. The product of the tactical groundwork in this ancient battle, the Trojan horse, emerges as a destructive cyber threat in today’s interconnected world. Trojans warrant attention even from the earliest identified form (PC-Write) in 1986, up until now.

Trojan horse program is a malware typically downloaded from the Internet and installed by unsuspecting users. Trojan comes in different forms, a gaming app, a stylish camera app or a legitimate banking app.  It also disguises as a software component or can mimic a seemingly authentic ad from an entity that you trust.

Trojans does not directly inflict damage, but typically carry payloads or other malicious actions that can range from mildly annoying to irreparably destructive. They may modify system settings to automatically start, jeopardize computer integrity, rake profit from collected data of individuals, or take over your computer and render it useless. Restoring affected systems may require procedures other than scanning with an antivirus program, specially the persistent ones that infects more devices.

An example of a Trojan horse that resurfaced very recently is Emotet. It is a banking malware that attempts to infect computers and steal personal information. This malware mostly spreads thru emails with infected attachments and embedded malicious links. Emotet has the capability to infect other connected computers. Moreover, it collects the victim’s contact list and sends itself to the email addresses in the contact list.
