For years, cybercriminals have been extorting victims by locking their computers with malware.
The hackers promise to give the victim their files back as long as they fork over the cryptocurrency—typically Bitcoin—within the stipulated time limit. Now, someone has added a new, perverse twist to this tried and tested scheme: demanding naked photographs instead of Bitcoin.
Researchers at MalwareHunterTeam, a research group focused on ransomware, spotted the software, called nRansomware on Thursday. The group posted a screenshot of the message that's displayed when a victim gets infected:
"Your computer has been locked," reads the message, which then asks the victim to email the hackers. "After we reply, you must send at least 10 nude pictures of you. After that we will have to verify that the nudes belong to you."
The message is displayed on top of an haphazard background made of several images of the fictional children's character Thomas the Tank Engine and a smiley face with the writing "FUCK YOU!!!" in bold. It's not clear how many people have been hit with this ransomware, or how serious the hackers behind it really are.
To some extent, the malware does appear to be legitimate. The file, nRansom.exe, is classified as malicious by several antivirus engines, including VirusTotal and Hybrid Analysis, which are both public malware repositories. Other users on Twitter also reported spotting more samples of this particular ransomware.
Malware can end up on these repositories if someone manually submits an entry and details what and does and how, or if malware is submitted and is then automatically analyzed. Experts attempted to infect a virtual machine with the malware but was unable to do so.
This could very well be a prank, given that it doesn't actually encrypt files, according to MalwareHunterTeam and another researcher who looked at the malware. "It is a screenlocker, so files aren't encrypted," MalwareHunterTeam told in a Twitter direct message. "We have no information about anyone getting infected with this."
The malware also appears to play looped music—from a file called your-mom-gay.mp3 that is actually the Curb Your Enthusiasm theme song—in the background, according to the MalwareHunterTeam. We contacted the hackers via the email address included in their ransom message. They didn't immediately respond to our questions.
In any case, while this ransomware is clearly gross, sadly, it's not unexpected. Hackers have for years used malware to spy on women and steal their nudes or access their webcams.
