removal by Gabriel E. Hall - - | Type: Trojans

Ursnif virus is a trojan horse used to steal sensitive data by recording users' keystrokes

  Ursnif trojan
Ursnif virus is a data-stealing trojan which you need to get rid of until it stole your money from bank accounts too.

The Ursnif virus is a dangerous Trojan horse that has been used to steal users' private data. Once inside the system, this trojan virus[1] launches the malicious svchost.exe and explorer.exe processes which are used to hide its presence on the system. Additionally, this multifunctional virus starts numerous activities behind the victim's back, including the distribution of other malware. However, the main virus activity is related to data tracking. Ursnif Trojan records every user's keystroke and then shares the recorded information with its developer via the TOR[2] network. In most of the cases, the virus arrives in the system via the malicious email attachments.

This trojan is designed to record various sensitive information about the user, including banking data, logins or passwords, web browsing activity, information about the victim's OS and device. All this recorded information is additionally shared with virus developers. Ursnif keylogger can also delete itself from the system once it receives such command.

This is a virus that evolves constantly and is active since 2007. It started targetting various financial institutions from the beginning and recently expanded to bigger organizations and changed distribution techniques and types of information to steal.

Ursnif virus is known to use different techniques as web injecting, man-in-the-browser or keylogging functionality. The latest attacks were based on spear phishing emails and the fact that malware deleted copies of itself after the initial process. These facts make this banking trojan more dangerous and difficult to detect or analyze. 

This virus steals various data about the user personally, the device and other account information like:

  • information from your email accounts;
  • various information from your browsers;
  • logins and passwords of your social media accounts;
  • banking website logins and passwords.

Ursnif virus changes various registry keys to keep affecting the system. People behind this threat are focusing on getting revenue from various background activities on your system or even stealing your banking credentials so get your money directly out of your bank accounts.

While there is no way to spot the infiltration of this trojan horse, you should note that the main way used by this malware to get into the system is spam. This trojan has been using seriously intelligent tactics that rely on infected Word documents that are filled with malicious macros. If you have recently been asked to enable macros to check the content of email's attachment, we highly recommend making sure that you are not infected. The easiest way to do that is to scan the system with updated anti-spyware.

If you have any doubts either you have this malware on the device or not, check your system with updated anti-spyware and perform Ursnif removal to save your personal information. To get rid of any viruses, use Reimage or any other anti-malware/anti-virus software. We do not recommend performing the removal manually as this is a dangerous cyber threat which can be related to numerous different components hidden on your computer. If you are blocked, reboot your PC to Safe Mode with networking first to disable the virus.

In most of the cases, antivirus programs detect the Ursnif Trojan horse as:

  • TR/Crypt.XPACK.Gen
  • Virus/Win32.PolyRansom.c
  • HEUR/Fakon.mwf
  • Win32.Doboc.Gen.1
  • Troj.Heur.LP.mE18
  • etc.[3]

Virus activity may lead you to serious privacy issues or money loss, so you need to remove Ursnif virus as soon as possible. This type of cyber intruder can download and install other malware, including ransomware-type viruses, which could lead you to the data loss. There is no need to keep yourself at such a risk. However, we should say one more time that you shouldn't try to delete the trojan horse manually as you can lead your system to serious trouble by removing needed system components.

Spam email campaigns have been spreading this virus around as legitimate attachments asking to enable macros

Researchers[4] have always been warning people that they shouldn't believe anything on the internet what looks too good to be true. That includes banner ads, in-text links, and spam emails as well.

Spam has also been a commonly used technique for trojan distribution. However,  when discussing Ursnif trojan horse, note that it relies on a slightly different distribution method. The main way used by its developers to deliver this malicious threat relies on Word documents filled with malicious macros. Once downloaded, such attachment asks you to enable macros and launches the virus in this way.

Other unique features about the distribution technique used by this banking trojan:

  • Compromised email accounts are used to reply to emails. The content of an email looks convincing;
  • The malicious payload is released when the user downloads the macro-filled documents. However, the Trojan waits until the attachment is closed to launch the process;
  • The safe-looking Word attachment also executes the PowerShell code. After this process, malware connects to URL and delivers the payload directly on the system;
  • The whole campaign is based on the fact that emails are sent from familiar services what increases the chances of people opening the infected file;
  • The most common pattern used to name these files is “the name of a local business or service_Statement”

You can avoid getting these intruders if you delete spam emails that are not from companies you know or services you do not use. Make sure to clean those suspicious emails from the email box more frequently and try to scan files before downloading them on the device. Pay more attention to these processes and do not open an email if you were not expecting that.
