Slashdot reader MojoKid quotes an article from Hot Hardware: A security researcher for AVG has discovered a new piece of ransomware called Fantom that masquerades as a critical Windows update. Victims who fall for the ruse will see a Windows screen acting like it’s installing the update, but what’s really happening is that the user’s documents and files are being encrypted in the background… The scam starts with a pop-up labeled as a critical update from Microsoft. Once a user decides to apply the fake update, it extracts files and executes an embedded program called WindowsUpdate.exe… As with other EDA2 ransomware, Fantom generates a random AES-128 key, encrypts it using RSA, and then uploads it to the culprit. From there, Fantom targets specific file extensions and encrypts those files using AES-128 encryption… Users affected by this are instructed to email the culprit for payment instructions. While the ransomware is busy encrypting your files, it displays Microsoft’s standard warning about not turning off the computer while the “update” is in progress. Pressing Ctrl+F4 closes that window, according to the article, “but that doesn’t stop the ransomware from encrypting files in the background.” Read more of this story at Slashdot.

Vice’s Motherboard, citing research and investigation (PDF) from security firm F-Secure, is reporting that a Fortune 500 company, the name of which hasn’t been unveiled, hired a ransomware gang to hack its competitors. From the article: In an exchange with a security researcher pretending to be a victim, one ransomware agent claimed they were working for a Fortune 500 company. “We are hired by [a] corporation to cyber disrupt day-to-day business of their competition, ” the customer support agent of a ransomware known as Jigsaw said, according to a new report by security firm F-Secure. “The purpose was just to lock files to delay a corporation’s production time to allow our clients to introduce a similar product into the market first.”In a statement to Motherboard, Mikko Hypponen said, “If this indeed was a case where ransomware was used on purpose to disrupt a competitor’s operation, it’s the only case we know of.” F-Secure adds that the consumer representative noted that “politicians, governments, husbands, wives — people from all walks of life contract [them] to hack computers, cell phones.” Read more of this story at Slashdot.
