You may think: ‘My PC is secure I am careful and I never open cat videos from unauthorized sites’. But imagine this scenario – One day you come back home, switch on your PC to watch your favorite kitty fails and then ‘BANG!’ – you suddenly see your whole computer being helpless against a dangerous virus, locking out your access and encrypting your files. What you see is a message, saying that you have committed different crimes against humanity like pedophilia, downloading illegal porn, mp3s or any other sick activities and you must pay a ‘fine’ to the FBI to get your files back.

FBI Header Ransomware – How Did It Infect My PC?

You may think that you are experienced in categorizing which sites are dangerous to your computer. But what if you have a suspicious browser extension on your PC that causes random pop-ups and redirects to third-party domains to flow? Or what if you had previously been affected with a rootkit virus on your computer that changes the locations you go to when you click on your search results on Google? These traps are so good that they have even made some experienced Power Users susceptible to them. Imagine you download your favorite program from a software site for the first time and you install it. Next thing you know while internetting, you get a malicious redirect that installs the malware by drive-by downloading it on your computer without your consent.

More about FBI Header Ransomware

Similar to FBI Moneypak, FBI uberarbeitet, FBI Cyber Department, FBI remanie, FBI renovo and other police ransowmare variants, this threat encrypts important files with strong encryption, making them next to impossible to decrypt in the best case. Once activated on the computer, the virus initially begins scanning the user PC for different file formats of relevance to the user (.pdf, .docx, .vdi, .xml, .txt, etc.). It then encrypts them with a strong algorithm, making them to look like corrupt for your PC.

After it has completed its initial phase, the virus then may leave a ransom note as your home page, your wallpaper or simply a document on your desktop. This nasty infection uses the reputation of FBI to induce fear in users and make them pay ransom money. Users report that except including instructions on payment methods that enable criminals to stay anonymous, it also had demanded 500$. The ransomware is also reported to feature a deadline after which the decryption keys are allegedly deleted forever.

And since it is a Trojan Horse after all, it might as well have downloader functions. Such may enable the nasty virus to not only track user activity on the PC at all times but also download other tools onto the PC that assist attackers. However, most ransomware criminals prefer only to encrypt the files and then break any active connection with the user because they cannot be traced back.
