What is Wulfric ransomware? And how does it implement its attack?

Wulfric ransomware is a file-encrypting malware designed to lock files and demand 0.5 BTC which is currently worth $485, as ransom for the decryptor. This newly-discovered malware uses an .aef extension in marking the files it encrypt. The instant its payload file is executed in the system, it will perform a series of modifications. It starts by connecting the system to a remote server controlled by the attackers and from this server other components will be downloaded and placed on system folders.
After its infiltration, it starts to execute its attack by dropping its malicious payload and performing a series of modifications in the system. It connects the infected machine to a remote server where it downloads the rest of its malicious components. After that, it gathers information using a data gathering module. It also utilizes stealth protection in order to prevent any program from interfering with its attack. It then scans the entire drive of the computer for files with the following extensions:
.txt, .doc, .docx, .xls, .xlsx, .pdf, .pps, .ppt, .pptx, .odt, .gif, .jpg, .png, .db, .csv, .sql, .mdb.sln.php, .asp, .aspx, .html, .xml, .psd, .frm, .myd, .myi, .dbf, .mp3, .mp4, .avi, .mov, .mpg, .rm, .wmv, .m4a, .mpa, .wav, .sav, .gam, .log, .ged, .msg, .myo, .tax, .ynab, .ifx, .ofx, .qfx, .qif, .qdf, .tax2013, .tax2014, .tax2015, .box, .ncf, .nsf, .ntf, .lwp
Once it finds its targeted files, it encrypts them using both the AES and RSA encryption algorithms and adds the .aef suffix to every encrypted file. After the encryption, it releases a file named “hacked.txt” which contains the following message:
“Attention, your files are encrypted!
your password is your PC.
