How Does .911 Ransomware Infect Victims
For the .911 file virus to infect a given computer successfully, the crooks behind it may engage in various different tactics. The primary of those is to use social engineering skills in order to trick potential victims into opening spam e-mail messages. These messages may have either a malicious web link or an e-mail attachment which only pretends to be important. The pretext they use to convince users to click on the malicious objects is that they are usually important invoices, bank account statements or other such documents. They may also pose as large companies or banks, like the following:
- PayPal.
- Amazon.
- FedEx.
- DHL.
- UPS.
Usually the cyber-crooks archive the e-mail attachments in .zip files so that they evade protection scanners from the e-mail providers. In order to check if an archive is malicious or not for free, you can use ZipeZip.
In some cases, the files which are used in order to cause an infection may not be executable files or scripts. They may also be malicious Microsoft Word (.docx) documents or .PDF files that may have malicious macros embedded. The documents do not infect your computer when you open them and appear normal. However, some of them claim they are locked and in order to see the content, you must click on “Enable Content” to enable macros. Those macros are in fact malicious and they are the ones that cause the infection itself in the following way:
.911 File Ransomware – Malicious Activity
Being a GlobeImposter variant, this virus is little different than the other viruses, at least at first glance. However, there are several key improvements and areas by which it can be recognized. One of those is it’s distinctive ransom note, which the virus drops after an infection takes place. It is named !SOS!.html and aims to get victims to pay a hefty ransom to restore the files.
Besides the main ransom note, the virus also drops it’s malicious files on the compromised computer. They may be located in the usually targeted Windows folders:
- %AppData%
- %Roaming%
- %Local%
- %LocalLow%
- %Temp%
After the files are dropped, the .911 file virus may delete the shadow volume copies on the computers infected by it. The virus performs this by executing a batch (.bat) script that inserts the following command as an administrator in Windows Command Prompt:
→ vssadmin delete shadows /for={DrivePartition} /oldest | /all | /shadow={Identification of the shadow copies}] /quiet
In addition to modifying the volume shadow copies of the infected machine, the virus may also add custom registry entries that automatically run the malicious files on Windows boot:
→ HKEY_LOCAL_MACHINE\Software\Microsoft\Windows\CurrentVersion\Run
HKEY_CURRENT_USER\Software\Microsoft\Windows\CurrentVersion\Run
HKEY_LOCAL_MACHINE\Software\Microsoft\Windows\CurrentVersion\RunOnce
HKEY_CURRENT_USER\Software\Microsoft\Windows\CurrentVersion\RunOnce
The Encryption of .911 Files Ransomware
When .911 GlobeImposter variant encrypts your files, your computer may slow down or even briefly freeze and during the encryption you will not be able to stop it as you won’t notice it, because it is a fast process.
What the virus does is it firstly targets the most often used documents, videos, pictures, archives and other files on your computer which may have the following file extensions:
→ “PNG .PSD .PSPIMAGE .TGA .THM .TIF .TIFF .YUV .AI .EPS .PS .SVG .INDD .PCT .PDF .XLR .XLS .XLSX .ACCDB .DB .DBF .MDB .PDB .SQL .APK .APP .BAT .CGI .COM .EXE .GADGET .JAR .PIF .WSF .DEM .GAM .NES .ROM .SAV CAD Files .DWG .DXF GIS Files .GPX .KML .KMZ .ASP .ASPX .CER .CFM .CSR .CSS .HTM .HTML .JS .JSP .PHP .RSS .XHTML.
