Bitcoin Ransomware attacks are on the rise as the Muhstik ransomware hits QNAP’s Network Attached Storage (NAS) devices with weaker passwords. The victims of the ransomware have been charged 0.09 BTC ($700) for accessing the decryption keys for their data.
One such ransomware victim has enacted a sweet revenge on the hackers after paying up the Bitcoin ransom to unlock his files.
According to BleepingComputer, a German programmer named ‘Tobias Fromel’ (aka ‘battleck’) released around 3,000 decryption keys along with free decryption software to help other victims of the Muhstik ransomware.
It is learnt that Fromel’s revenge tactics could actually be illegal as per his recent clarification on the BleepingComputer forum. He has, however, assured the forum readers that he has done nothing wrong.
Fromel’s noble intentions may actually protect him from the legal consequences of such a Cybercrime. Nevertheless, the entire incident has come under the radar of one security researcher who has alerted the authorities about it.
Despite offering his ransomware-decryption software for free, several victims have started tipping him with bitcoin donations. So far, his effort has earned him net revenue of 0.01148348 BTC ($94 approx.).
Meanwhile, FBI has been cautioning ransomware victims from paying hackers to restore files as it could motivate them for further attacks.
Despite the FBI warning, as many as three hospitals in Alabama have already paid up the hackers behind Ryuk ransomware to unlock access to compromised systems in early October.
In related news, Emsisoft has reported that Fromel’s decryption software won’t work for victimised ARM-based QNAP devices. All such devices could make use of Emisoft’s in-house Muhstik decryption tool which can be downloaded here.
