Bandook Malware


Bandook is a recently released Trojan horse virus for Windows that has already managed to infect a big number of computers. Bandook sneaks inside its victims’ PCs without getting noticed by the antivirus and begins to run different harmful processes in the targeted system.


Multiple antivirus programs intercepting the Bandook malware

As you probably already know, the representatives of the Trojan horse family are some of the sneakiest and stealthiest forms of computer malware. They oftentimes don’t show any red flags that could uncover their presence on the attacked machine and, when it comes down to newer versions such as Bandook, even the antivirus that’s present on the attacked computer may fail to spot the virus on time. The main reason why new Trojan viruses oftentimes don’t get spotted by the security tools that people have on their computers has to do with the over-reliance of many of the conventional antivirus solutions on their databases. Using the antivirus’ database to spot an incoming malware attack is effective but only as long as the attacking virus has been added to the database. This allows the antivirus to recognize the Trojan and stop it. However, if the virus is a new one, such as Bandook, the security tool is unlikely to detect the infection and do anything to stop it. This leaves you with your own vigilance as a tool to detect the malware threat. As we said, Trojans oftentimes don’t trigger any visible signs of their activities in the computer. Still, there are certain potential red flags that may, on some occasions, draw one’s attention to the ongoing malware infection.

Such red flags could be the increased use of CPU, GPU, and RAM on the computer even when no resource-intensive apps or programs are being run. Also, some more aggressive Trojans could cause the computer to crash into the so-called Blue Screen of Death. A Blue Screen of Death (BSOD for short) crash almost always indicates that there’s some significant problem with the system or the hardware. A Trojan horse attack could most certainly be the cause behind such a crash so if your computer experiences this, be sure to check your machine for Bandook (the removal guide at the bottom will help you with this). Other irregularities such as changes in the system or the browser settings, corrupted files, program errors, etc., are also possible Trojan horse symptoms so be on the lookout for those as well.

The Bandook Malware

The Bandook malware have several different abilities and can be tasked with different goals depending on the situation. Taking over the computer and forcing it to mine cryptocurrency for the hackers as well as spying on the user and stealing sensitive data from him or her are two very likely ways in which a threat like the Bandook malware could be used.

In addition, Ransomware cryptoviruses can oftentimes be distributed with the help of a Trojan so if Bandook or Wup.exe are on your computer, it is possible that there could be a hidden Ransomware infection as well. In all cases, it is crucial to respond quickly to the Trojan horse infection so that no irreversible damage is done to your machine. To help you with the removal, we’ve prepared a detailed guide for the removal of the threat that you can find down below.
