How to remove BiggyLocker Ransomware and decrypt .$big$ files

What is BiggyLocker Ransomware

BiggyLocker is a ransomware-type virus that makes most files stored on a system totally inaccessible. This process is more known as data encryption. It involves strong AES and RSA algorithms meant to assign military-grade ciphers, which make self-decryption next to impossible. Alike other malware of this type, BiggyLocker assigns the .$big$ extension to each encrypted piece of data. For instance, a file like 1.pdf will be changed to 1.pdf.$big$ and reset its original icon. Then, as soon as this part of encryption is done, the virus moves on to creating a text note called read_me.txt. It is dropped on a desktop and contains ransom instructions.

As developers claim, it is impossible to recover the blocked files without their help. To do this, victims are requested to pay for the special decryption software held by cybercriminals themselves. The price for such is 120$ to be transferred in Bitcoin. Once victims have paid the demanded ransom via the crypto address, they should therefore contact extortionists using their e-mail address (cyberlock06@protonmail.com). After this, victims should supposedly get the promised decryption tools to regain access to their data. Unfortunately, most cybercriminals behind ransomware infections tend to fool their victims and do not send any tools even after receiving the ransom. This is why it is better to rely on decryption by yourself. Although there are no third-party tools able to decrypt BiggyLocker files for free, you can still recover your data using backup copies. If you do not have such created and stored on external storage prior to the infection, then you are likely to remain with files encrypted unless you pay the ransom. Whatever the case, it is necessary to delete BiggyLocker from your computer to prevent further encryption. You can do this using our guidelines below.

How BiggyLocker infected your computer

It is common to see ransomware infections distributed via e-mail spam letters, trojans, unprotected RDP configuration, fake software cracking tools meant to bypass the license, backdoors, keyloggers, unreliable pirated or free software download from dubious pages, and many other methods exploited by malware developers. Although the way you could be infected is individual, most people fall into the ransomware trap thanks to e-mail spam. This method is widely abused due to its accessibility and effectiveness. As a rule, extortionists send hundreds of identical messages disguised as legitimate. Potential victims are likely to see “official”, “urgent”, “important”, or similar tags inside of these letters. In most cases, such messages end up designed to spread malicious software. If somebody asks you to open .pdf, .docx, .exe, or .js files inside of the message, then it is a sign of danger. Cybercriminals tend to use these file formats to hide malware and force users into opening them. If you suspect such messages to be fake and malicious, better delete them and block the sender address to avoid accidental clicks. Keep in mind that malware developers capitalize on inexperienced and inattentive users. This is why it is important to keep your head on a swivel whilst surfing the web. Never open or interact with dubious software you are not sure is safe. Below, we have prepared an ultimate guide that will help you protect your PC against various malware types in the future.

BiggyLocker Ransomware uses some techniques to exploit this. One of the best services and programs for easy automatic online backup is iDrive. It has the most profitable terms and a simple interface. You can read more about iDrive cloud backup and storage here.

3. Do not open spam e-mails and protect your mailbox

Malicious attachments to spam or phishing e-mails are the most popular method of ransomware distribution. Using spam filters and creating anti-spam rules is good practice.
