The agency’s announcement tells us that:
No More Ransom(www.nomoreransom.org) is a new online portal aimed at informing the public about the dangers of ransomware and helping victims to recover their data without having to pay ransom to the cybercriminals…
…The project has been envisioned as a non-commercial initiative aimed at bringing public and private institutions under the same umbrella. Due to the changing nature of ransomware, with cybercriminals developing new variants on a regular basis, this portal is open to new partners’ cooperation.
The site includes:
- Crypto Sheriff – a form for helping victims try to find out which malware they’re affected by and whether a decrypter is available. Sounds like a potentially useful resource, even though the little graphic reminds me a little of the late, lamented Lemmy rather than a hi-tech search facility. Somewhat similar to MalwareHunter’s ID Ransomware facility.
- A Ransomware Q&A page
- Prevention Advice
- An About page
- Advice on how to Report a Crime
- And a limited range of decryption tools from Kaspersky (mostly) and Intel.
Infosecurity Magazine’s commentary notes that:
‘In its initial stage, the portal contains four decryption tools for different types of malware, including for CoinVault and the Shade Trojan. In May, ESET claimed that it had contacted TeslaCrypt’s authors after spotting a message announcing they were closing their ‘project’ and offered a decryption key.
‘Raj Samani, EMEA CTO for Intel Security, told Infosecurity that both Intel Security and Kaspersky had developed decryption tools to apply against Teslacrypt, and these will be posted to the website shortly.
Well, I’m not in a position to compare the effectiveness of various TeslaCrypt decrypters, and I do understand that it’s important for the “The update process for the decryption tools page …[to]… be rigorous.” Kaspersky in particular has a good reputation for generating useful decrypters. And the AVIEN site is certainly not here to pursue ESET’s claim to a portion of the PR pie. Still, there are decrypters around from a variety of resources apart from the companies already mentioned (see Bleeping Computer’s articles for examples). I hope other companies and researchers working in this area will throw their hats into the ring in response to Europol’s somewhat muted appeal for more partnerships, so that the site benefits from a wider spread of technical expertise and avoids some of the pitfalls sometimes associated with cooperative resources. As it states on the portal:
“the more parties supporting this project the better the results can be, this initiative is open to other public and private parties”.
Here are some links for standalone utilities that I’ve listed on the ransomware resource pages here. [Note, however, that these haven’t been rigorously checked, or not by me at any rate.]
Standalone Decryption Utilities
I haven’t personally tested these, and they may not work against current versions of the ransomware they’re intended to work against. Note also that removing the ransomware doesn’t necessarily mean that your files will be recovered. Other companies and sites will certainly have similar resources: I’m not in a position to list them all.
Included with tools for dealing with other malware.
18-4-2016 [HT to Randy Knobloch] N.B. I haven’t tested these personally, and recommend that you read the ‘More technical information’ and ‘Detailed usage guide’ before using one of these.
