What is Hancitor?

Hancitor is a high-risk trojan-type virus. Developers proliferate this malware using various spam email campaigns such as Here Is Your Fax Email Virus, AT&T Invoice Email Virus, and many others. After successful infiltration, Hancitor introduces other malware to infect the system. Therefore, this malware opens 'backdoors' for other viruses to infiltrate.

Hancitor malware

As mentioned above, Hancitor is proliferated using spam email campaigns. Developers send thousands of deceptive email messages that encourage users to open attached documents. These attached files are malicious - they stealthily install Hancitor into the system. This is where the chain infection begins. By opening the malicious attachments, users inadvertently allow Hancitor to enter their computers. Immediately after infiltration, Hancitor executes scripts that install other trojans (for example, Pony). Infiltrated malware is very dangerous. Most of these viruses gather sensitive information, such as saved logins/passwords, website URLs visited, keystrokes, and so on. Cyber criminals might gain access to personal accounts (banks, social networks, and so on). In this way, they can steal victims' identities and perform malicious tasks, such as online purchases, money transfers, and so on. Therefore, the presence of malware distributed by Hancitor can lead to serious privacy issues and significant financial loss. If you have recently opened any suspicious attachments, there is high a probability that your computer is infected. Therefore, scan it with a reputable anti-virus/anti-spyware suite and eliminate all detected threats.

There are dozens of trojan-type viruses proliferated using email spam campaigns (for example, Adwind, Emotet, TrickBot, and FormBook), however, only small percentage proliferate other viruses and, in most cases, they distribute ransomware. Trojans commonly record sensitive information and save it on remote servers - they pose a significant threat to your privacy and computer safety and must be removed immediately.

How did Hancitor infiltrate my computer?

As mentioned above, Hancitor promotioncampaigns typically distributes malicious Microsoft Office documents. Immediately after opening these files, users are asked to enable macro commands, however, in doing so, they inadvertently grant malicious attachments permission to download and install Hancitor into the system. Although this malware distribution method is simple and effective, it is not flawless. Note that malicious files are only able to download malware if they are opened using tools from the Microsoft Office suite. For example, if a .doc file is opened using any program other than MS Word, the malware will not be downloaded. In addition, Hancitor targets the Microsoft Windows Operating System only and, therefore, users or other platforms do not have to worry.

How to avoid installation of malware?

Lack of knowledge and careless behavior are the main reasons for computer infections. The key to safety is caution. Therefore, pay close attention when browsing the Internet. We strongly recommend that you carefully analyze each email attachment received. Files that are irrelevant or have been sent by a suspicious/unrecognizable email address should never be opened. These emails should be deleted without reading. Furthermore, have a legitimate anti-virus/anti-spyware suite installed and running - these programs delete malicious files before they perform any actions. If you believe that your computer is already infected, we recommend running a scan with Malwarebytes for Windows to automatically eliminate infiltrated malware.

Update April 16, 2020 - Due to the recent outbreak of Coronavirus (COVID-19) infection cyber criminals are taking advantage of the situation and starting various email spam/scam campaigns to spread malware, extract money from unsuspecting users and perform other malicious actions. Hancitor is not an exception. Here's an example of scam emails that are presented as notifications from Humana Inc. Emails encourage users to open attached files which inject Hancitor into the system.

manual malware removal step 5Check the list provided by the Autoruns application and locate the malware file that you want to eliminate.

You should write down its full path and name. Note that some malware hides process names under legitimate Windows process names. At this stage, it is very important to avoid removing system files. After you locate the suspicious program you wish to remove, right click your mouse over its name and choose "Delete".

locate the malware file you want to remove

After removing the malware through Autoruns application (this ensures that the malware will not run automatically on the next system startup), you should search for the malware name on your computer. Be sure to enable hidden files and folders before proceeding. If you find the filename of the malware, remove it.

searching for malware file on your computer

Reboot your computer in normal mode. Following these steps should remove any malware from your computer. Note that manual threat removal requires advanced computer skills. If you do not have these skills, leave malware removal to antivirus and anti-malware programs. These steps might not work with advanced malware infections. As always it is best to prevent infection than try to remove malware later. To keep your computer safe, install the latest operating system updates and use antivirus software.

To be sure your computer is free of malware infections, we recommend scanning it with Malwarebytes for Windows.
