What is Pzdc ransomware? And how does it carry out its attack?
Pzdc ransomware is the name of a newly spotted crypto-malware that uses a “.pzdc” extension to mark the files it encrypt. Pzdc ransomware is designed to encrypt data on servers using GNU Privacy Guard, also known as GnuPG and demands a ransom of 100 monero from its victims. It was discovered in the second half of June and seems to focus on targeting Russian-speaking users.
Once it starts to execute its attack, it drops its payload file in the system and initiates a sequence of malicious activities with the purpose of plaguing essential system settings and processes. It downloads other malicious components and places them to system folders. It then modifies the registry keys and sub-keys like Run and RunOnce in the Windows Registry to allow the automatic execution of the attack every time a user turns on the infected computer which makes its attack persistent.
After completing the modifications in the system, Pzdc ransomware will start to encrypt data in a targeted system using a military-grade encryption algorithm. It then opens a text file named 1_VIRUS_SHIFROVALSHIK.txt which has quite a lengthy-message. Here are some parts of the ransom note:
“Hello dear friend! I want to share with you the success of our team. We have reached a new level in our skills and now we only encrypt databases and what looks like their backup copies. We no longer need photos, documents Word, Excel and other information. We collect money only from rich people. If at that moment you watched YouTube or PornHub on your home desktop and saw this message, don’t worry, we didn’t touch your files. Delete this file and do not open any more letters from unknown addresses with attachments. Sorry that ** ali in your desktop.
If you’re the same successful manager … Dude, you’re out of luck))) There are stupid people in your team and you have to pay for their stupidity.

So that you do not get lost tabs total 7: Manifest, Rules, Communication with the Administration, Runion Wiki and the box you need. In the recipient line, enter this address bbfd729a5a2f. Do not close the mailbox window or save the link which is highlighted in green in the line “access your messages via this link, save it and keep it secret”.

Paying the ransom is strongly not recommended which is why you must not give in to these crooks’ demands. The best thing you can do when infected with this ransomware Trojan is to remove it carefully from your system first and then try out free recovery options, be it through a free decryption software or using the Windows Previous versions feature.
