If you cannot open your images, documents, or files and they have a “.$big$” extension, then your computer is infected with the BiggyLocker ransomware.
What is the BiggyLocker ransomware?
The BiggyLocker ransomware is a file-encrypting ransomware infection that restricts access to data (documents, images, videos) by encrypting files with the “.$big$” extension. It then attempts to extort money from victims by asking for “ransom”, in the form of Bitcoin, in exchange for access to data.
When you are first infected with the BiggyLocker ransomware it will scan your computer for images, videos, and important productivity documents and files such as .doc, .docx, .xls, .pdf. When these files are detected, the ransomware will encrypt them and change their extension to “.$big$”, so that you are no longer able to be open them.
Once the BiggyLocker ransomware has encrypted the files on your computer, it will display a file that contains the ransom note and instructions on how to contact the authors of this ransomware.
This is the ransom note that the BiggyLocker ransomware will show to its victims:
Your files are encrypted with a AES and RSA algorithm , it is unbreakable .
you can’t recover your files without our decryption service , the price is 120 USD in bitcoin
after the payment you must email us at : email@example.com
to prove us that you pay.
– do not use any decryption tools because those tools will just destroy your files , making recover impossible .
– do not rename your files .
If your computer is infected with this ransomware, we recommend that you contact the following government fraud and scam sites to report this attack:
- In the United States, go to the On Guard Online website.
- In Australia, go to the SCAMwatch website.
- In Canada, go to the Canadian Anti-Fraud Centre.
- In France, go to the Agence nationale de la sécurité des systèmes d’information
- In Germany, go to the Bundesamt für Sicherheit in der Informationstechnik website.
- In Ireland, go to the An Garda Síochána website.
- In New Zealand, go to the Consumer Affairs Scams website.
- In the United Kingdom, go to the Action Fraud website.
- If your country or region isn’t listed above, we recommend that you contact your country or region’s federal police or communications authority.
Unfortunately, it is not currently possible to decrypt the files encrypted by the BiggyLocker ransomware. It may, though, be possible in the future if the decryption keys are recovered from the cybercriminals’ servers. Therefore, if you do not plan on paying the ransom, it is advised that you make an image of the encrypted drives so that you can possibly decrypt them in the future.
How did the BiggyLocker ransomware get on my computer?
The BiggyLocker ransomware is distributed via spam email containing infected attachments or by exploiting vulnerabilities in the operating system and installed programs.
Here’s how the BiggyLocker ransomware might get on your computer:
- Cyber-criminals spam out an email, with forged header information, tricking you into believing that it is from a shipping company like DHL or FedEx. The email tells you that they tried to deliver a package to you, but failed for some reason. Sometimes the emails claim to be notifications of a shipment you have made. Either way, you can’t resist being curious as to what the email is referring to – and open the attached file (or click on a link inside the email). And with that, your computer is infected with the BiggyLocker ransomware.
- The BiggyLocker ransomware was also observed attacking victims by exploiting vulnerabilities in the program installed on the computer or the operating system itself. Commonly exploited software includes the operating system itself, browsers, Microsoft Office, and third-party applications.
