What is PyAesCrypt ransomware? And how does it execute its attack?

PyAesCrypt ransomware is yet another file-encrypting virus discovered in April 2019. It can cause irreversible damage to a compromised computer. Based on the analysis of this crypto-malware, it seems to be a new variant of Python ransomware. It leaves its encrypted files with a “.locked” extension and drops twenty pieces of ransom notes that has the same content.

Once it infects a computer, it follows a predesigned behavioral pattern. It launches a combination of information gathering module and stealth protection module which are both used to obtain data about the infected computer and user as well as protect the malware from any security programs installed in the system. It scans the computer for any security software that might interfere with the execution of the crypto-malware. This process is done via signature scans that looks for antivirus engines as well as virtual machine hosts and debug environments. After it finds them, it terminates them and in some cases, delete the security software altogether. Aside from these capabilities, PyAesCrypt ransomware can also manipulate files – it can delete and modify user files. It can also obtain administrative privileges in the system and sends report to a remote server controlled by the attackers.

During its attack, PyAesCrypt ransomware may schedule system tasks so it can automatically run on system boot. After that, it will look for certain files to encrypt. It may target common user-generated files such as:

.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. DOC .DOCX .LOG .MSG .ODT .PAGES .RTF .TEX .TXT .WPD .WPS .CSV .DAT .GED .KEY .KEYCHAIN .PPS .PPT .PPTX .INI .PRF Encoded Files .HQX .MIM .UUE .7Z .CBR .DEB .GZ .PKG .RAR .RPM .SITX .TAR.GZ .ZIP .ZIPX .BIN .CUE .DMG .ISO .MDF .TOAST .VCD SDF .TAR .TAX2014 .TAX2015 .VCF .XML Audio Files .AIF .IFF .M3U .M4A .MID .MP3 .MPA .WAV .WMA Video Files .3G2 .3GP .ASF .AVI .FLV .M4V .MOV .MP4 .MPG .RM .SRT .SWF .VOB .WMV 3D .3DM .3DS .MAX .OBJ R.BMP .DDS .GIF .JPG .CRX .PLUGIN .FNT .FON .OTF .TTF .CAB .CPL .CUR .DESKTHEMEPACK .DLL .DMP .DRV .ICNS .ICO .LNK .SYS .CFG

Once it finds these files, it encrypts them using the AES cipher. After the encryption, PyAesCrypt ransomware drops twenty copies of ransom notes that are named “ReadMe 0.txt”, “ReadMe 1.txt”, “ReadMe 2.txt”, “ReadMe 3.txt” and so on, up until “ReadMe 19.txt”. These text files have the same ransom message that states:

“ENGLISH
