The “No More Ransom” is an initiative by the National High Tech Crime Unit of the Netherlands’ police, Europol’s European Cybercrime Centre and two cyber security companies – Kaspersky Lab and McAfee – with the goal to help victims of ransomware retrieve their encrypted data without having to pay the criminals.
Since it is much easier to avoid the threat than to fight against it once the system is affected, the project also aims to educate users about how ransomware works and what countermeasures can be taken to effectively prevent infection. This initiative is open to other public and private parties.
The team has created a repository of keys and applications that can decrypt data locked by different types of ransomware.
To know the type of ransomware affecting your device, you can fill a form in their website that enables them to check whether there is a solution available. If there is, they will provide you with the link to download the decryption solution.
The “No More Ransom” gave prevention advice and released a document to prevent ransomware attacks few of them are:
- Back-up! Back-up! Back-up! Have a recovery system in place so a ransomware infection can’t destroy your personal data forever. It’s best to create two back-up copies: one to be stored in the cloud (remember to use a service that makes an automatic backup of your files) and one to store physically (portable hard drive, thumb drive, extra laptop, etc.). Disconnect these from your computer when you are done. Your back up copies will also come in handy should you accidentally delete a critical file or experience a hard drive failure.
- Use robust antivirus software to protect your system from ransomware. Do not switch off the ‘heuristic functions’ as these help the solution to catch samples of ransomware that have not yet been formally detected.
- Keep all the software on your computer up to date. When your operating system (OS) or applications release a new version, install it. And if the software offers the option of automatic updating, take it.
- Trust no one. Literally. Any account can be compromised and malicious links can be sent from the accounts of friends on social media, colleagues or an online gaming partner. Never open attachments in emails from someone you don’t know. Cybercriminals often distribute fake email messages that look very much like email notifications from an online store, a bank, the police, a court or a tax collection agency, luring recipients into clicking on a malicious link and releasing the malware into their system.
- Enable the ‘Show file extensions’ option in the Windows settings on your computer. This will make it much easier to spot potentially malicious files. Stay away from file extensions like ‘.exe’, ‘.vbs’ and ‘.scr’. Scammers can use several extensions to disguise a malicious file as a video, photo, or document (like hot-chics.avi.exe or doc.scr).
- If you discover a rogue or unknown process on your machine, disconnect it immediately from the internet or other network connections (such as home Wi-Fi) — this will prevent the infection from spreading.
