Back in February we wrote about a new ransomware called Thanatos that was encrypting victim's data, but contained flaws that would not allow the authors to decrypt a victims files even if they paid. Thankfully, the Cisco Talos Group was able to find a method to break the encryption routine.
Security researchers from AhnLab, a South Korea-based cyber-security firm, have created decrypters for some versions of the Magniber ransomware.
This week's article combines the previous week's stories as well. Lots of small in-dev ransomware over the last two weeks, but also a few RaaS (Ransomware as a Service) implementations were released and decryptor for GandCrab was released.
Bitdefender has released a free decrypter that helps victims of GandCrab ransomware infections recover files without paying the ransom.
Belgian Federal Police together with Kaspersky Lab have released a free decryption tool for some versions of the Cryakl ransomware.
While we are continuing to see less ransomware developed and more attackers focusing on a few large-impact strains, Ransomware is unfortunately not dead. This was particularly apparent this week with plenty of news to go around.
An modified version of the open-source ransomware project called desuCrypt is being used as the base code for a new ransomware family being actively distributed. This family currently has two variants being distributed, with one appending the .insane extension and the other appending .DEUSCRYPT.
This week we had our fair share of smaller variants being distributed or created, but the big news was by far the release of Magniber and the use of the Hermes ransomware as a cover to steal money from a Taiwan bank. With the release of Magniber we also see the downward spiral of Cerber,.
It has been a slow week in terms of new releases, which is always a good thing. Still lots of small crapware being released that will never have much wide distribution. We also have some good news, which is the release of a NemucodAES decryptor by Emsisoft. This allows victims of this ransomware to get their files back for free.
Fabian Wosar of Emsisoft has been able to crack the decryption used by the NemucodAES ransomware so that victims can get their files back for free. This guide will walk you through using the decryptor and provide a brief explanation on the NemucodAES Ransomware.
Been a great week for victims, with decryptors coming out for BTCWare, Cryptomix, Executioner, and the release of the original Petya key. Otherwise, it has been a lot of NotPetya news and numerous smaller variants being released.
The author of the original Petya ransomware — a person/group going by the name of Janus Cybercrime Solutions — has released the master decryption key of all past Petya versions.
For the most part, mostly in-development ransomware released this week. No really major ransomware variants released that are much of a threat. The big news, though, is that Kaspersky was able to figure out how to crack the decryption for the Jaff Ransomware and release a free decryptor.
The author of a new ransomware strain named Executioner has bungled the tool's encryption routine, which means security researchers will be able to decrypt victims' files. The good news is that this ransomware is not the subject of a massive distribution campaign, so the number of affected victims is low if any even exist.
Fedor Sinitsyn, a senior malware analyst at Kaspersky Labs, has discovered a weakness in the Jaff ransomware and was able to release a decryptor for all current variants For those who were infected with Jaff and had their files encrypted with the .jaff, .wlu, or .sVn extensions, this decryptor can recover your files for free.
This has been a week of pure junk ransomware releases and decryptors. As most of these smaller ransomware variants never make it into actual distribution, I call this a win for the good guys. The big news this week is the release of the master decryption key for XData and updated an updated decryptor for Amnesia2.
In what has become a welcome trend, today another ransomware master decryption key was released on BleepingComputer.com. This time the key that was released is for the XData Ransomware that was targeting the Ukraine around May 19th 2017.
This week was a busy with lots of little variants discussed below and a new version of the Jaff Ransomware circulating via MALSPAM. The big news is that AES-NI decided to close shop and has starting releasing the master decryption keys so people can get their files back for free.
From new ransomware and WannaCry imitations to decryption keys being released, ransomware developers continue to keep us busy.. This article will keep you up-to-date on the latest news and developments in ransomware.
