Besides making your files locked, this virus additionally does a lot of harm to your system.

Ransomware has actually been a major problem for the last 4 years. It is hard to imagine a more harmful malware for both individuals and corporations. The algorithms used in Win32/BadJoke.KG (typically, RHA-1028 or AES-256) are not hackable – with minor exclusions. To hack it with a brute force, you need to have more time than our galaxy already exists, and possibly will exist. However, that malware does not do all these horrible things instantly – it can require up to several hours to cipher all of your files. Thus, seeing the Win32/BadJoke.KG detection is a clear signal that you need to begin the removal process.

Where did I get the Win32/BadJoke.KG?

Typical methods of Win32/BadJoke.KG injection are standard for all other ransomware variants. Those are one-day landing sites where users are offered to download and install the free software, so-called bait e-mails and hacktools. Bait emails are a relatively modern strategy in malware distribution – you get the e-mail that mimics some standard notifications about shipments or bank service conditions changes. Inside of the e-mail, there is a corrupted MS Office file, or a link which opens the exploit landing page.

Malicious email spam

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

Avoiding it looks pretty easy, however, still demands tons of recognition. Malware can hide in different places, and it is much better to stop it even before it gets into your PC than to depend on an anti-malware program. Common cybersecurity knowledge is just an essential thing in the modern-day world, even if your relationship with a computer stays on YouTube videos. That may keep you a lot of money and time which you would spend while trying to find a solution.
