USB Killer, $50, lets you easily fry almost every device

Last year we wrote about the “USB Killer”—a DIY USB stick that fried almost everything (laptops, smartphones, consoles, cars) that it was plugged into. Now the USB Killer has been mass produced—you can buy it online for about £50/$50. Now everyone can destroy just about every computer that has a USB port. Hooray.

Aggressive design caused Samsung Galaxy Note 7 battery explosions

In September, the first reports of Samsung Galaxy Note 7 batteries exploding hit social media.  At first, Samsung identified the issue as one relating to the lithium polymer battery manufacturing process by Samsung SDI, where too much tension was used in manufacturing, and offered to repair affected phones.  But several weeks later, some of the batteries in those replacement units also exploded once they were in the hands of customers — causing Samsung to make the bold decision to not only recall everything, but to cancel the entire product line.

San Francisco transit system hit with ransomware

The city’s light rail system, MUNI, was compromised in what appears to be a non-targeted ransomware attack, and riders were given free transit on Saturday until the issue was resolved. The attacker claimed that MUNI’s data was encrypted and demanded a ransom in bitcoin.

San Francisco Muni hacker gets hacked back

Revenge is sweet, but irony is sweeter. Apparently, the hacker who infiltrated San Francisco’s Muni transportation system late last week fell victim to his own horrible personal cyber hygiene.

According to security reporter Brian Krebs, a separate individual infiltrated the Muni hacker’s own email using nothing more than the ransom note provided by the hacker himself. And he pulled it off using the oldest trick in the book.

Chip-and-PIN credit cards hacked easily, Black Hat conference proves — RT America

It only takes small modifications to equipment to bypass the chip-and-PIN protections and enable unauthorized payments, multiple researchers at the Black Hat convention in Las Vegas, Nevada demonstrated on Wednesday.

The new cards, which began rolling out in the US in October 2015, use technology ‒ called Europay, MasterCard and Visa (EMV) ‒ that has long been standard in Europe. It’s designed to prevent the duplication of cards and crack down on cards that have been stolen. The tech works by inserting the chip into a card reader, then entering a personal identification number, or PIN. However, in the US, the financial industry only requires a signature after the chip is read, which is less secure. Some retailers have ignored the new technology altogether, and just ask customers to swipe their chip cards, the same as a traditional credit or debit card. At Black Hat 2016, as in past conferences, hackers focused on the more secure chip-and-PIN requirements.

China censors WeChat without users realizing by focusing on group chats, a Citizen Lab study finds

A new study from The Citizen Lab, a research group at the University of Toronto, reveals that censorship on WeChat occurs primarily in group chats rather than one-on-one chats between two people, and often in such a way where the sender of a text isn’t even aware a piece of text has been scrubbed. The discoveries illuminates how China’s government attempts to keep its citizens blind to the scope of its censorship regime.
