Locky ransomware replaced with dummy file, rendered ineffective

A white hat hacker has hacked into the Locky ransomware making it effectively harmless. Avira wrote in a blogspot that one of the strains of malware they were looking turned out to be nothing. The strain was not even as harmful as the malware should be.

Carlsen noted that a benevolent hacker might had taken control of the command server and control server of the malware and replaced the file with an ineffective one.

“It seems that someone was able to access one of the command and control servers and replaced the original Locky ransomware with a dummy file. And I do mean dummy in the fullest expression of the word,” said Carlsen. “Now, I don’t believe that cyber-criminals themselves would have initiated this operation because of the potential damage to their reputation and income stream.”
