KnowBe4 Alerts Users: CryptoLocker Threat Variant Goes Stand Alone
KnowBe4’s Ransomware “We Pay if You’re Hit” Protection Gives Businesses a Safety Net
Tampa Bay, FL (PRWEB) June 24, 2014
Even with the recent international law enforcement "Operation Tovar" shutting down Cryptolocker operations, it appears the number one ransomware Trojan is back in business. KnowBe4 reports a new strain of the infamous CryptoLocker has been found. The new Trojan does not rely on the 2048-bit RSA encryption and does not need any communication with a Command & Control server to work. It operates stand-alone, and the extensions of affected files are switched to .cryptolocker after encryption.
According to KnowBe4 CEO Stu Sjouwerman, “Despite US Dept of Justice efforts in early June to finger the Russian evil genius allegedly behind CryptoLocker, Evgeniy Mikhailovich Bogachev, in the recent international law enforcement ‘Operation Tovar’, new ransomware has shown up. As we predicted, this would not keep ransomware variants from proliferating. This is why we are offering our customers payment of their ransom if they get hit after doing our Kevin Mitnick Security Awareness training. It may very well be the most effective safety net against ransomware.”
According to KnowBe4, the Trojan encrypts data on the affected computer, but uses an encryption method that is weaker than the original. If you are a malware expert and know how to reverse engineer code, the encryption code can possibly be broken. In order to regain access to the locked files, analysis of this CryptoLocker spin-off instructs the victim to access a location in the Tor network to receive details about the ransom payment.
KnowBe4 says that judging by the choice of the encryption algorithm and the method for receiving payment, this CryptoLocker variant does encrypt all the files it can get its hands on, and by preying on assumptions regarding the CryptoLocker brand name, these miscreants could still make a profit as not many users will know how to decrypt their files.
Sjouwerman also said, “More ransomware copycats will show their ugly heads this year. Law enforcement recommends not paying any ransom for two reasons: first to discourage the criminal practices, and second it’s uncertain if they will keep their end of the bargain and provide the decryption. While we agree, many companies may be forced to pay ransom if their backups failed rather than experience months or years of lost work. A great way to prevent files taken ransom is effective security awareness training.
