Ransomware has been a headache for the last 4 years. It is challenging to picture a more harmful malware for both individuals and businesses. The algorithms used in VHO:Backdoor.Win32.Remcos (typically, RHA-1028 or AES-256) are not hackable – with minor exclusions. To hack it with a brute force, you need a lot more time than our galaxy actually exists, and possibly will exist. However, that malware does not do all these horrible things immediately – it can take up to a few hours to cipher all of your files. Hence, seeing the VHO:Backdoor.Win32.Remcos detection is a clear signal that you need to begin the elimination procedure.

Where did I get the VHO:Backdoor.Win32.Remcos?

General ways of VHO:Backdoor.Win32.Remcos injection are common for all other ransomware examples. Those are one-day landing web pages where victims are offered to download the free app, so-called bait e-mails and hacktools. Bait e-mails are a quite modern strategy in malware spreading – you get the e-mail that mimics some standard notifications about deliveries or bank service conditions modifications. Inside of the e-mail, there is a malicious MS Office file, or a web link which leads to the exploit landing page.

Malicious email spam

Malicious email message. This one tricks you to open the phishing website.

Avoiding it looks fairly easy, but still demands tons of focus. Malware can hide in various spots, and it is much better to stop it even before it goes into your system than to rely on an anti-malware program. General cybersecurity awareness is just an essential thing in the modern world, even if your interaction with a PC remains on YouTube videos. That can save you a lot of money and time which you would certainly spend while trying to find a solution.
