What is Gru Ransomware

Gru Ransomware blocks access to personal data to earn money on demanding a so-called ransom. Such malware runs file encryption with strong algorithms that prevent users from approaching free decryption. The virus adds the .gru extension to each encrypted file. To illustrate, 1.pdf or any other similar file will change to 1.pdf.gru and reset its original icon. Such changes will be applied to most types of data stored on your system. To regain access to your data, victims are asked to follow instructions outlined inside of the read_it.txt text note, which is created after encryption.

Cybercriminals state there is no way to decipher your data without buying special software. The price of such software is established at 1,500$ to be paid in BTC. The payment address can be found at the very bottom of the text note. Unlike other ransomware programs, Gru developers do not ask their victims to establish any sort of contact with them (by e-mail or Tor link). Therefore, It is uncertain how are they going to send you the decryption software once you deliver the money. Thus, trusting Gru Ransomware in terms of paying the ransom is quite a huge risk. Even though its developers might be the only figures able to decrypt your entire data, we recommend against sending your money. It is way better to delete Gru Ransomware and recover your data using backup copies. If you do not have much copies available to offset the encrypted data, it is necessary to remove Gru Ransomware from your computer nonetheless. Otherwise, it may continue running data encryption or even spread to neighboring networks. More information on removal and PC protection can be found further down this guide.

How Gru Ransomware infected your computer

There are a plethora of distribution methods that can be used by cybercriminals to deliver ransomware-like infections. The most popular are trojans, fake software updaters, P2P (peer-to-peer) networks (eMule, torrents, etc.), fake download sources (free file hosting websites), and spam emails bundled with malvertising attachments. Trojans are used to open “backdoors” for other malware to infiltrate your system. Fake update tools infect the system by exploiting obsolete software flaws or simply downloading and installing malware rather than updates. P2P networks and other shady download sources present malware as legitimate software and trick users into downloading it. E-mail spam usually incorporates infectious attachments that come in various formats (e.g. PDF, Word documents, EXE, or JavaScript files). If you dare click on one of these files, you are likely to catch ransomware into your PC. This is why attentiveness and self-awareness should be in priority whilst surfing the web. Below, you will find a list of advice on how to protect your system from such threats in the future.
