IcedID Trojan


IcedID is a malicious piece of code that seeks to sneak inside the system without being detected. IcedID is known as a Trojan horse and is kept accountable for online crimes such as data theft, money fraud and extortion, personal abuse, and more.


Multiple antivirus programs detect the IcedID Malware

IcedID has been recently added to the well-known Trojan horse malware category. Therefore, since this is a very new threat, there is a high chance that even advanced and trusted antivirus programs may not detect it when the computer is attacked. The main explanation why some protection programs may let such new threats to sneak through lies in the way malware is generally identified.

The IcedID Trojan

The IcedID trojan is mostly distributed with another trojan called Emotet. Criminals send thousands of email messages that encourage users to open attached files (usually Microsoft Office documents) that are infected with the IcedID trojan.

A typical antivirus software will utilize the virus definitions of its database to detect new security risks, such as Trojans, Spyware, Ransomware, etc. Normally the antivirus developers update the database every time a new virus type is developed. Such updates, however, don’t happen immediately, as it takes some time for the security researchers to thoroughly study a new virus and include it in the virus databases. Until then, the security software would probably not stop the newly published threat. In other words, the attacks of recent Trojans such as IcedID may remain invisible until the antivirus gets its updates. Many people may not even know that they have been compromised. Besides, some Trojans may have the ability to deliberately block the antivirus on the computer to prevent their detection and stop the victim from using new or updated security software that can remove it.

One possible way to detect a threat like IcedID is to closely pay attention to every unusual system activity, error or problem that occurs because, sometimes, these things may serve as red flags to a hidden malicious activity in the background of the OS. In some situations, a virus like IcedID may cause very severe disruptions which cannot be easily overlooked. Such are the infamous Blue Death Screen crashes and common system problems of no specific reason such as unusual errors, sudden shut downs of programs and processes, higher than normal CPU or RAM usage, unknown tasks in the Task Manager, etc. All these could potentially be linked to the presence of a Trojan virus. That is why, if we can give you one general piece of advice it would be to carefully investigate and remove all malfunctions of the Operating System with the help of reliable optimization and malware-removal tools.

In most cases, however, the Trojan will be almost invisible and its victims may not have a clue about the danger that is lurking on their device until they face a major system disruption or become a victim of a cybercrime. Ideally, a full computer scan with trusted security software should be performed, because, more frequently than not, Trojans may invite other malware such as Spyware, Ransomware and other viruses inside the infected computer without your knowledge.
