Ransomware has been a headache for the last 4 years. It is difficult to realize a more hazardous malware for both individual users and companies. The algorithms used in Win32/Packed.Themida.IBV (typically, RHA-1028 or AES-256) are not hackable – with minor exclusions. To hack it with a brute force, you need to have a lot more time than our galaxy currently exists, and possibly will exist. However, that virus does not do all these horrible things immediately – it can take up to several hours to cipher all of your files.

Where did I get the Win32/Packed.Themida.IBV?

Common tactics of Win32/Packed.Themida.IBV spreading are common for all other ransomware variants. Those are one-day landing sites where users are offered to download and install the free program, so-called bait emails and hacktools. Bait e-mails are a relatively modern tactic in malware spreading – you receive the email that imitates some routine notifications about deliveries or bank service conditions shifts. Inside of the e-mail, there is an infected MS Office file, or a link which leads to the exploit landing site.

Malicious email spam

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

Preventing it looks quite easy, however, still needs a lot of recognition. Malware can hide in various places, and it is far better to prevent it even before it gets into your system than to rely on an anti-malware program. Simple cybersecurity awareness is just an essential item in the modern-day world, even if your relationship with a computer stays on YouTube videos. That may save you a great deal of time and money which you would certainly spend while seeking a fixing guide.
