The OpenSSH project has received a patch that prevents private keys from being stolen through hardware vulnerabilities that allow hackers to access restricted memory regions from unprivileged processes. The same approach could be used by other software application to protect their secrets in RAM until the issues are fixed in future generations of SDRAM chips and CPUs.

A botnet is a collection of internet-connected devices that an attacker has compromised. Botnets act as a force multiplier for individual attackers, cyber-criminal groups and nation-states looking to disrupt or break into their targets’ systems. Commonly used in distributed denial of service (DDoS) attacks, botnets can also take advantage of their collective computing power to send large volumes of spam, steal credentials at scale, or spy on people and organizations.

The ransomware attacks in Baltimore and other US cities appear to have a common thread: they're using NSA tools on the agency's home soil. In-the-know security experts talking to the New York Times said the malware in the cyberattacks is using the NSA's stolen EternalBlue as a "key component," much like WannaCry and NotPetya. While the full list of affected cities isn't available, San Antonio and the Pennsylvania city of Allentown have reportedly been victims of EternalBlue-based campaigns.
