We had been looking at ways to prevent this ransomware from encrypting files even on computers that were not protected by Bitdefender antivirus and we realized we could extend the idea.” “The new tool is an outgrowth of the Cryptowall vaccine program, in a way. That is where Bitdefender’s new tool comes in, according to the firm’s Chief Security Strategist Catalin Cosoi: But that is not the case for all ransomware, especially those samples that have few coding and cryptographic errors. Sure, researchers sometimes leverage flaws in the malware code to publish decryption keys or to create a downloadable decryption tool. In the meantime, attackers continue to infect targets with other malicious samples, with some even going so far as to hack a hospital’s website in order to disseminate Tesclacrypt ransomware.įor those who are exposed to crypto-ransomware, there’s little hope that they will get their files back unless they have a secure backup of their data or are prepared to pay the ransom. The hospital ultimately paid a ransom fee of $17,000 to have its computer systems restored. The Locky ransomware first appeared on the scene in February when it was identified as the malware that shuttered the computer systems of Hollywood Presbyterian Medical Center in southern California. ![]()
