What is MSIL/Packed.MultiPacked.CK virus?

MSIL/Packed.MultiPacked.CK is ransomware-type malware. It looks for the documents on your disk drives, ciphers it, and then asks you to pay the ransom for getting the decryption key. Besides making your files inaccessible, this virus also does a lot of harm to your system.

Ransomware has been a headache for the last 4 years. It is hard to realize a more damaging malware for both individual users and organizations. The algorithms utilized in MSIL/Packed.MultiPacked.CK (usually, RHA-1028 or AES-256) are not hackable – with minor exclusions. To hack it with a brute force, you need more time than our galaxy currently exists, and possibly will exist. However, that virus does not do all these unpleasant things instantly – it may take up to several hours to cipher all of your files. Therefore, seeing the MSIL/Packed.MultiPacked.CK detection is a clear signal that you have to start the clearing process.

Where did I get the MSIL/Packed.MultiPacked.CK?

Usual ways of MSIL/Packed.MultiPacked.CK distribution are typical for all other ransomware variants. Those are one-day landing websites where users are offered to download and install the free program, so-called bait e-mails and hacktools. Bait emails are a pretty new method in malware distribution – you receive the email that simulates some standard notifications about shippings or bank service conditions shifts. 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 quite uncomplicated, however, still requires tons of awareness. Malware can hide in various places, and it is far better to prevent it even before it invades your PC than to rely upon an anti-malware program. Standard cybersecurity knowledge is just an important thing in the modern-day world, even if your interaction with a PC stays on YouTube videos. That may keep you a great deal of money and time which you would spend while looking for a fix guide.
