What is Delta Plus Ransomware

Delta Plus is a ransomware-type virus that uses cryptographic algorithms to encrypt personal data. It assigns strong ciphers that are hard to decode without special decryption tools held by cybercriminals themselves. To buy these tools, victims are requested to send the equivalent of 6,000 USD in BTC to a crypto address. The price for decryption may be also reduced to 3,000 USD if you manage to complete the payment within the first 72 hours after being infected. All of this information is disclosed inside of the text note called Help Restore Your Files.txt, which is created as soon as the encryption of files is done. Delta Plus appends the .delta extension to all affected files. For instance, a file like 1.pdf will change to 1.pdf.delta and lose its original icon. After these changes, users will no longer be able to access their files until they pay the required ransom.

Before purchasing the necessary decryption tool, cybercriminals also offer a so-called guarantee – to send 1 file for test decryption for free. This file should be small and contain no valuable information. Communication with cybercriminals can be established directly through their e-mail address (decryptdelta@gmail.com). Unfortunately, files affected by Delta Plus Ransomware are chained by strong ciphers indeed, which makes their decryption without cybercriminals almost unapproachable. You can give it a try using the third-party tools we mentioned below, but there is a risk it will fail and result in permanent damage. This is why the best solution whenever it comes to encrypted files is to recover them via backup copies. If you had them created and stored in an external location prior to the infection, then you can get your data back easily. In other cases, the only, yet risky way to avoid paying the ransom is using other third-party tools. You can find more information on both removal and restore options down below.

How Delta Plus Ransomware infected your computer

Crypto-extortioners like Delta Plus Ransomware are usually distributed via malicious e-mail spam messages, trojans, unprotected RDP configuration, backdoors, keyloggers, fake software cracking tools, unreliable updates, pirated programs, and other content downloaded from unofficial resources. However, the most abused method of proliferating malware is usually considered to be e-mail spam letters. These letters are often disguised as something legitimate or urgent and contain malicious attachments or links leading to fake download pages. The range of attachments that cybercriminals use is often with MS Office documents, PDFs, Archive, Executable, or JavaScript files altered to launch installation scripts. Website links can also be seen quite often. They lead to pages with fake legitimate software asked to be downloaded. No matter which distribution method you put under dissection, it will work itself out only thanks to users’ inexperience and inattentiveness. To decrease the risk of getting infected with malware to the very minimum, users should use only trusted and official installers, avoid cracking tools, suspicious advertisements, and various websites that can distribute malvertising software. Besides removal instructions, we also prepared a full security guide to protect yourself against such threats in the future down below.
