What is Ursnif?

Ursnif (also known as Gozi or Dreambot) is high-risk trojan-type virus designed to record various sensitive information. This virus typically infiltrates systems without permission, since developers proliferate it using spam email campaigns (e.g., "TicketSales Email Virus", "Swisscom Email Virus", etc.) and fake Adobe Flash Player updaters promoted via deceptive websites. These sites are notorious for the promotion of various adware-type applications.

Immediately after infiltration, Ursnif records user-system information, such as keystrokes, saved logins/passwords, web browsing activity, system information, and so on. Therefore, Ursnif's developers might gain access to personal accounts for social networks, banks, emails, etc. These people aim to generate as much revenue as possible. Therefore, there is a high probability that hijacked accounts will be misused through online purchases, money transfers, and so on. This behavior can lead to serious privacy issues and significant financial loss. Be aware that Ursnif is also capable of performing a number of actions on the system (e.g., steal/clear cookies, reboot the system, take screenshots, etc.). More importantly, this virus is capable of the downloading and installing other executables. Therefore, the presence of Ursnif might lead to various system infections. Fortunately, many anti-virus suites are capable of detecting and eliminating Ursnif from the system. Therefore, if you suspect that your system is infected with Ursnif, immediately scan it with a reputable anti-virus program and eliminate all threats. In addition, remove all dubious applications and browser plug-ins (as mentioned, deceptive websites are likely to promote adware-type apps).

There are many trojan-type viruses similar to Ursnif available online, inluding TrickBot, FormBook, Hancitor, LokiBot, Emotet, etc. Some distribute malware, whilst others record information, perform malicious actions, etc. The behavior differs slightly, but these viruses remain very similar. All pose a direct threat to your privacy and computer safety. Therefore, viruses such as Ursnif must be eliminated immediately.

How did Ursnif infiltrate my computer?

As mentioned above, Ursnif is proliferated using spam email campaigns and fake software (Adobe Flash Player) updaters. Spam campaigns deliver messages encouraging users to open various malicious documents (in most cases, Microsoft Office documents). Once opened, they download and install Ursnif onto the system. Fake system update tools infect computers by exploiting old software bugs/flaws or downloading and installing malware rather than promised updates. Note that these updaters are promoted by malicious sites that deliver messages claiming that certain software is outdated (even when it is not).

How to avoid installation of malware?

To prevent this situation, be very cautious when browsing the Internet and updating software. Think twice before opening email attachments. If the file is irrelevant/unexpected or has been received from a suspicious email address, do not open it. Furthermore, keep installed applications and operating systems up-to-date. To achieve this, use implemented functions or tools provided by the official developer only. Having a reputable anti-virus/anti-spyware suite installed and running is also paramount, since these tools are likely to detect and eliminate malware before malicious actions are performed. The main reasons for computer infections are poor knowledge and careless behavior - the key to safety is caution. If you believe that your computer is already infected, we recommend running a scan with Spyhunter for Windows to automatically eliminate infiltrated malware.

Update January 25, 2019 - Cyber criminals are distributing Ursnif trojan using malicious MS Word documents. These files, once opened, ask to enable macro commands. The attachment contains a macro command that executes a base64 PowerShell command. This follows by execution of another PowerShell command which connects to a remote Command & Control server and downloads, and executes Ursnif.

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 the 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, be sure to 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 Spyhunter for Windows.
