Detailed Information on AVCrypt ransomware

 

AVCrypt ransomware is a kind of notorious system threat which is especially designed by the hackers to disable installed anti-virus programs and security tool on compromised machine even if the victimized users make the successful ransom payment. At the time of writing this article, it is still unclear that the malware is in-development file-encoder virus or a system wiper infection. Although, it drops a ransom notification on victim's machine identified as '+HOW_TO_UNLOCK.txt' file which contains no information on how to pay asked ransom money or contact the virus developers. Surprisingly, cyber extortionists behind AVCrypt ransomware focuses on removing installed or active security application right after its successful invasion.

AVCrypt ransomware

To be more precise, the threat mainly targets the popular anti-virus programs named Malwarebytes and Windows Defender to stop their working operation by deleting some crucial Windows services. In addition to that, the malware checks for the installed anti-virus program registered with Windows Security Center and uses WMIC to delete it. Based on the recent research report, AVCrypt ransomware does not have the ability to delete all security applications, which means that some of them can be secure and used to perform its complete removal from affected machine. It has features of both file-encrypting and wiper. This ransomware might remove some crucial Windows services which causes issues with the proper working of installed operating system.

Working Principles of AVCrypt ransomware

Right after its successful intrusion on targeted Windows computer, the malware does not start encoding the files stored onto it immediately, but connects affected machine with a Command & Control server. In addition to that, it first delete the installed anti-virus and transfer some vital data like timezone, encryption key, and the version of installed OS to its remote C&C server. Once AVCrypt ransomware encrypts the specific file types, it adds '+' prefix onto them and drops a ransom note on each folder containing enciphered files.

The ransom note displays by AVCrypt ransomware does not contain any specific data, but only a message i.e. 'lol n'. Therefore, it is expected that the ransomware is still in-development phase and might be updated anytime to cause big issues on targeted machines. However, Microsoft detects this threat as Ransom:Win32/Pactelung.A that can be removed using a powerful and credible anti-malware shield. It alters Windows registry entries, clean its files and event logs, wipes autorun entry and ransomware processes as well. Hence, it is strongly recommended to use a reputable anti-malware like the one recommended below to delete AVCrypt ransomware.
