Atilla Stealer Virus

Also Known As: Atilla Stealer remote access trojan
Type: Trojan
Damage level: Severe

What is Atilla Stealer?

The Atilla Stealer program is a Remote Access Trojan (RAT) that cyber criminals use for malicious purposes, specifically, to steal various personal information.

They trick people into downloading and installing this program and then use the stolen data/information to generate revenue. Atilla Stealer runs in the system background and people who have computers infected by this RAT are usually not aware of this.

Cyber criminals promote Atilla Stealer on the dark web (forums and website). It can be purchased by anyone and then used to infiltrate other people's computers.

Once installed, it allows users (cyber criminals) to take screenshots, log IP addresses and information stored on the clipboard, display fake messages, recover passwords, change icons, hide files and change their assemblies, and perform various other functions.

People who have inadvertently installed this program might experience financial loss, privacy issues, have their accounts (passwords) stolen, computers infected, and so on. Cyber criminals can use Atilla Stealer to disguise infected files as harmless and to trick people into installing malicious programs.

Data copied from the clipboard could be used to steal personal, sensitive information. Screenshots could also be used with malicious intent. Passwords stolen with Atilla Stealer might be used to hack banking, emails, and other important accounts. If there is a reason to believe that this program is installed on your computer, it should be removed immediately.

There are many programs that cyber criminals use to steal personal information and cause data/financial loss and other serious problems.

They use various channels to trick people into downloading and installing them. Note, however, that most people install these rogue programs unintentionally, believing that they are downloading and installing other, legitimate software. Examples of other programs used with similar intentions are Bolik, NetSupport Manager, Orcus, and Agent Tesla.

How did Atilla Stealer infiltrate my computer?

Various ways are used to trick people into downloading and installing unwanted programs or computer infections. Typically, cyber criminals use spam campaigns, Trojans, software 'cracking' programs, untrustworthy software download sources or fake software updaters.

To proliferate them through spam campaigns, cyber criminals send emails that contain attached files or web links. Included attachments are usually Microsoft Office documents, PDFs, archives such as RAR, ZIP, executables (.exe and other files), JavaScript files, and so on. These files cause unwanted installations when people open them.

Trojans are malicious programs that, if installed, cause chain infections. These programs proliferate viruses. Tools ('cracks') used to activate paid software can also be used to proliferate malicious programs. Cracks download and install malware rather than activating programs or operating systems.

Peer-to-peer (P2P) networks (torrent clients, eMule, and others), freeware download and free file hosting websites, unofficial pages and other similar download sources are often used to infect systems by presenting malicious files as legitimate and harmless.

People cause unwanted installations when they download and open these files. Fake, unofficial tools that supposedly update installed software cause computer infections by exploiting outdated software flaws/bugs or downloading and installing malware rather than updates, fixes, and so on.

How to avoid installation of malware?

To prevent computers infections, do not open files (attachments) or links that are presented in emails received from unknown/suspicious email addresses. These emails may seem official and legitimate, however, that does not mean that they can be trusted. Download software from official websites and use direct download links.

Other (aforementioned) tools should not be used, since they often include rogue applications (malicious files) that could lead to computer infections. Software should be updated using only implemented functions or tools provided by official software developers.

Software activation should be done correctly, without using 'cracking' tools - these programs are illegal and often cause damage (computer infections). Have a reputable anti-virus or anti-spyware suite installed and enabled. These tools can detect and remove malicious files before they can do any harm to the operating system.

If you believe that your computer is already infected, we recommend running a scan with Combo Cleaner Antivirus for Windows to automatically eliminate infiltrated malware.

manual malware removal step 4In the Autoruns application, click "Options" at the top and uncheck the "Hide Empty Locations" and "Hide Windows Entries" options. After this procedure, click the "Refresh" icon.

Click 'Options' at the top and uncheck 'Hide Empty Locations' and 'Hide Windows Entries' options

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 Combo Cleaner Antivirus for Windows.
