In November 2013, the operators of CryptoLocker launched an online service that claimed to allow users to decrypt their files without the CryptoLocker program, and to purchase the decryption key after the deadline had expired; the process involved uploading an encrypted file to the site as a sample and waiting for the service to find a match ...
The department said Tuesday that it was releasing a decryption tool to help victims free their computer systems from the malicious software used by the group. The strain of software, ...
The No More Ransom Project is an initiative by the Netherlands' police's National High Tech Crime Unit, Europol’s European Cybercrime Centre, Kaspersky Lab and McAfee to help ransomware victims recover their data without paying a ransom. [158] They offer a free CryptoSheriff tool to analyze encrypted files and search for decryption tools. [159]
easside-ng is an automated tool which attempts connection to a WEP Access Point without knowing the encryption key. It uses the fragmentation attack and a remote server (which can be hosted with the tool buddy-ng) in the attempt to recover an encrypted packet, exploiting the AP which will decrypt it for the attacker.

Deniable encryption makes it impossible to prove the origin or existence of the plaintext message without the proper decryption key. This may be done by allowing an encrypted message to be decrypted to different sensible plaintexts, depending on the key used.
The Florida company whose software was exploited in the devastating Fourth of July weekend ransomware attack, Kaseya, has received a universal key that will decrypt all of the more than 1,000 ...
In cryptography, the EFF DES cracker (nicknamed "Deep Crack") is a machine built by the Electronic Frontier Foundation (EFF) in 1998, to perform a brute force search of the Data Encryption Standard (DES) cipher's key space – that is, to decrypt an encrypted message by trying every possible key.
In transparent decryption, the decryption key is distributed among a set of agents (called trustees); they use their key share only if the required transparency conditions have been satisfied. Typically, the transparency condition can be formulated as the presence of the decryption request in a distributed ledger. [2]
