WTF?! Chinese-made chips used in popular contactless cards contain hardware backdoors that are easy to exploit. These chips are compatible with the proprietary Mifare protocol developed by Philips spin-off NXP Semiconductors and are inherently "intrinsically broken," regardless of the card's brand.
What just happened? Security researchers at this year's Def Con have presented findings regarding a long-standing albeit recently discovered vulnerability in AMD processors called "Sinkclose." Though rather hard to exploit, the security flaw can potentially yield catastrophic results for any system unlucky enough to fall victim to it.
Microsoft hasn't spotted an attack in the wild yet, but it will take time to develop a mitigation
What just happened? Another day, another security flaw discovered in Microsoft Windows. The latest arrives courtesy of research presented at the Black Hat security conference, which revealed a design flaw in the Windows Update architecture that allows critical OS components to be downgraded by manipulating the update process.
WTF?! If you thought your laptop, desktop, or server was protected by Secure Boot, think again. A new vulnerability dubbed "PKfail" has left Secure Boot wide open on hundreds of PC and devices across several major tech brands. Researchers at cybersecurity firm Binarly just dropped a bombshell report showing how a leaked cryptographic key has essentially nuked the security guarantees of Secure Boot for over 200 product models.
A lost password proved to be a blessing in disguise
Finding the flaw: A cryptocurrency holder reached out to renowned hacker Joe Grand about two years ago for help in regaining access to an encrypted digital wallet on his computer reportedly containing about $2 million worth of Bitcoin. Grand turned down the offer. You see, Grand specializes in hardware skills and Michael stored his crypto in a software based wallet.
