SADStory is a file-encrypting malware that targets Windows users. This ransomware is distributed through malicious email attachments and websites that host exploit kits.Once it encrypts a user's files, it demands a ransom be paid to receive the decryption key. SADStory uses strong encryption algorithms, which makes it difficult to decrypt files without the decryption key. It uses a combination of RSA and AES encryption algorithms to encrypt files.

History

SADStory was first discovered by malware researcher Michael Gillespie in August 2016. At that time, it was being distributed through email attachments that claimed to be invoiced.In October 2016, the ransomware was spotted being distributed through the Neutrino Exploit Kit. This exploit kit is usually delivered via malicious advertisements on websites. When a user visits a website that is displaying a malicious advertisement, they can be infected with SADStory Ransomware without realizing it.It has also been distributed through spam emails that contain a zip file attachment. These zip files usually contain a JavaScript file that, when opened, will download and install this ransomware on the victim's computer.Since it was first discovered, there have been many variants of this ransomware created. These variants usually differ in the way they are distributed and the amount of ransom they demand.

How does SADStory Ransomware work?

When SADStory is installed on a victim's computer, it will scan the hard drive for certain types of files to encrypt. Once it has encrypted a file, it will append the ".sadstory" extension to the end of the filename.For example, a file named "sample.jpg" would be renamed to "sample.jpg.sadstory" after it has been encrypted. The ransomware will also create a text file named "SADSTORY-DECRYPT.txt" in each folder that contains encrypted files. This text file contains instructions on how to pay the ransom and decrypt the files.The ransom demand varies depending on which variant of SADStory Ransomware you are infected with, but it is typically between 0.5 and 2 Bitcoins. At the current Bitcoin exchange rate, this equals between $500 and $2000. This ransomware will give you a deadline to pay the ransom, and if you don't pay within that time frame, the price will double.SADStory Ransomware is a serious threat to your computer and your data. Be sure to take steps to protect your computer and your data from this and other ransomware threats. Use a reliable antivirus program, keep your operating system and software up-to-date, and avoid clicking on links or opening attachments in emails from unknown senders.If you have been infected with SADStory, we recommend that you do not pay the ransom. There is no guarantee that you will receive the decryption key even if you do pay, and your money will go towards funding future cybercrime. Instead, you should focus on restoring your files from a backup, if you have one.If you don't have a backup, some file recovery methods may work, but they are not guaranteed to work and may require technical expertise. We recommend that you seek out professional help if you decide to attempt file recovery.

Furthermore, there is no public decryption tool available for SADStory Ransomware.
