"Critical Flaw in PuTTY SSH Client Enables Private Key Recovery"

A vulnerability in PuTTY versions 0.68 through 0.80 could allow attackers to recover private keys used for cryptographic signatures, potentially leading to unauthorized access to SSH servers or the ability to sign commits as a developer. The flaw, tracked as CVE-2024-31497, was discovered by researchers at Ruhr University Bochum and has been fixed in PuTTY version 0.81. Other software using the vulnerable PuTTY versions, such as FileZilla, WinSCP, TortoiseGit, and TortoiseSVN, may also be impacted and users are advised to take preventive action.

Intel and MSI Private Keys Leaked in Cyber Heist

Private keys used to protect PCs from hidden malware, generated by MSI to use with Intel's BootGuard technology, were leaked when data belonging to MSI was stolen and dumped online. The leaked private keys affect 116 products, hindering the ability for MSI computers to use Intel's BootGuard to block bad, unwanted, or malicious firmware. If miscreants can bypass the BootGuard technology, they could gain full system access, steal sensitive data, and perform all sorts of illicit activities without being noticed as their malware runs underneath the OS and antivirus packages.

FTX's Downfall: Hubris, Incompetence, and Greed.

FTX CEO John Ray III criticized the company's use of Amazon Web Services (AWS) to store private keys for its hot wallets, which were compromised in November 2021, resulting in the loss of $432 million worth of funds. Ray stated that FTX kept virtually all crypto assets in hot wallets and did not use offline, air-gapped, encrypted, and geographically distributed laptops to secure crypto assets. He also mentioned that FTX lied about using cold storage and recommended that FTX.US make better use of cold wallet storage, but no such system was put in place prior to the bankruptcy.
