A variant of the Power Worm ransomware is infecting computers, encrypting their data files, and throwing away the encryption key, all because of an error in the malware's programming.
The Power Worm malware is a PowerShell-based ransomware, which uses the Windows PowerShell to initiate and execute its malicious activity.
The Windows PowerShell is a framework developed by Microsoft to allow developers to automate tasks and operations on Windows PCs.
Trend Micro researchers were the ones that discovered the Power Worm ransomware back in March 2014, when they detected an active campaign targeting Word and Excel files.
The hacker made an error in the encryption routine's code
This particular variant of the Power Worm ransomware targets a broader scope of data file types, but this is not the particular "feature" that makes it stand out amongst other ransomware families.
