What is BlueSky Ransomware

BlueSky Ransomware is a devastating file encryptor. It restricts access to data and requests victims to pay a fee for its return. While running encryption of system-stored data, the virus also assigns the .bluesky extension to each affected sample. For instance, a file named 1.pdf will change to 1.pdf.bluesky and reset its original icon. Since then, files will be no longer accessible. To make victims pay the ransom, cybercriminals layout identical decryption instructions in both # DECRYPT FILES BLUESKY #.html and # DECRYPT FILES BLUESKY #.txt text notes, which are created after encryption.

Inside, extortionists say the only case when files can be recovered is if victims purchase a special decryption key and software. They also say that any third-party attempts to decrypt files without the help of cybercriminals may result in permanent damage to data. Victims are thereafter instructed to download Tor Browser and visit the provided web link. After following that, victims will be able to see the price for decryption and additional information such as how to create a wallet and purchase cryptocurrencies as well. The decryption price is set at 0.1 BTC ≈ $2,075 and is said to double in 7 days after the ransomware attack. Cybercriminals also offer to test decryption, as victims can send one blocked file and get it decrypted for free. Ransomware developers tend to do this in order to validate their trustworthiness and boost victims’ confidence in paying the ransom. Despite this, it is still strongly advised not to pay the ransom and collaborate with cybercriminals. Many fool their victims and do not send any promised decryption set of tools afterward. We should also warn you that decrypting data without the help of cybercriminals is almost impossible due to the strong encryption algorithms and keys the ransomware creates. The only best option to avoid paying the ransom is to use backup copies of data. If such are available on external devices, you can easily use them for restoration. You can also make a backup of already encrypted data and try some third-party tools presented in our article, however, they might not have enough capacity to help with BlueSky decryption. Note that prior to trying any recovery methods that exclude ransomware developers, it is important to prevent virus operation by deleting it from your system. Do this in our guide below and choose which recovery method fits you the most.

How BlueSky Ransomware infected your computer

Infections like ransomware have multiple distribution methods. Users may get them through malicious email messages, fake software updates or installers, trojans, network vulnerabilities, backdoors, keyloggers, and so forth. Cybercriminals often refer to spreading malware via e-mail spam messages, as mentioned above. They attach maliciously-modified files (.DOCX, .PDF, .EXE, .JS, .RAR, . ZIP, etc.) and ask users to open them up. The biggest reason why so many users fall into this trap is that such messages are disguised as something legitimate (DHL, FedEx, DPD, IRS, Banks, etc.). Therefore, inexperienced and inattentive users become victims of such distribution techniques. It is important to download software only from verified resources, visit trustworthy pages, and do not follow any questionable content. We also advise you to read our tutorial below as there will be some useful information about malware protection to capitalize on.
