AngryKite is the name given to a new variant of the KRider ransomware. The name probably comes from an executable file that contains part of the malicious files for this ransomware that is called angryKite_v3.exe. Once that file is executed, your data will become encrypted and the cryptovirus will leave a ransom note with instructions for recovery. Read on below to see how you could try to potentially restore parts of your data.

.NumberDot File Virus – Infection

AngryKite ransomware could spread its infection via different methods. The payload file that initiates the malicious script for this ransomware, which in turn infects your computer machine, is circling the Internet and a malware sample has been found by malware researchers. You can see the VirusTotal detections for different security programs of that sample by checking the screenshot below:

AngryKite ransomware might also distribute its payload file on social media websites and networks for file-sharing. Freeware that is found on the Web could be presented as useful but at the same time could hide the malicious script for the cryptovirus. Refrain from opening files just as you have downloaded them, especially if they come from suspicious sources such as links or e-mails. Instead, you should scan them beforehand with a security tool, while also checking the size and signatures of these files for anything that seems out of the ordinary. You should read the ransomware preventing tips thread in the forum.

.NumberDot File Virus – Specifics

AngryKite ransomware is dubbed that way, due to the main file, which is responsible for infecting computers, called angryKite_v3.exe. That file is considered the payload dropper. Once it is executed, it will encrypt files and place the .NumberDot extension to them. Another executable file is involved with processes regarding the virus and that file is KRider.exe. Malware researchers which have analyzed the files, have concluded that the ransomware is a variant of the .kr3 KRider Virus.

AngryKite ransomware could make entries in the Windows Registry to achieve persistence, launch and repress processes in Windows. Some entries are designed in a way that will start the virus automatically with each launch of the Windows Operating System, and one such entry is outlined right here:


The ransom note will show up after the encryption process is complete. The note is written in English. Inside, you will see instructions to call a phone number and that access to your computer is cut off, much like the many scams involving the YOUR COMPUTER HAS BEEN BLOCKED message. You can preview the ransom message in the picture below:

That ransom message reads the following:

anonymous encryption on your computer. You would not be able to access the files on your computer
Your System May have Found (2) Malicious Viruses Rootkit.Encypt & Trojan.Spyware
Your Personal & Fincancial information MAY NOT BE SAFE
Your system has encryption ransomware
which may permanently encrypt your data
Please call immediately to avoid further damage
Toll free 1-855-545-6800
Your UID

The ransom note and any instructions from the AngryKite ransomware should not be followed. If you call the number, it may cost you a fortune, plus the cybercriminals on the other side of the line may try to extort you for money, or try to extract personal information from you. You should NOT under any circumstance contact the crooks. Your files may not even get restored, and nobody could give you a guarantee for it.
