UnblockUPC Ransomware – How Does It Infect

To cause a successful infection, the UnblockUPC virus may use a combination of different tools and methods with techniques that may cause an unnoticed slithering onto a victim computer. Such tools may be:

  • Exploit Kits.
  • Spam bots.
  • Malware obfuscators.
  • Malicious JavaScript.
  • File Joiners.
  • Disposable mail service.

Such tools may allow the malware to be spread in various forms, main of which is via having the UnblockUPC”s malicious executable sent to a user via e-mail as an attachment that seems to be legitimate. Usually most spam messages may include several different notifications such as:

  • “ Open this invoice.”
  • “ Please see the attachment below.”
  • “ Your purchase is complete. See delivery details below.”

Such deceitful messages often get users to open the e-mail attachment, and that is the main goal of the cyber-criminals behind UnblockUPC ransomware.

Another method of having this virus infect a given PC is by letting users download it by themselves via torrents, just like the the RAUM tool. Some even report that hackers have hacked accounts of torrent uploaders with a good reputation to conceal malware disguised as a legitimate torrent, like a game or useful software.
There are many methods by which UnblockUPC can spread, but the most likely technique may be via e-mail since 70% of ransomware viruses use this strategy simply because it is effective.
