Flawed Cisco update threatens to stop APs from getting further patches
Cisco admins are scrambling to patch a critical flash memory overflow vulnerability in over 200 Cisco Systems IOS XE-based models of wireless access points (APs), caused by a recent flawed software update. If the issue is not corrected quickly, the AP’s memory will become so flooded that new software updates will be blocked and the AP rendered insecure, or possibly…
DNS Security is often inadequate, and network engineers should get more involved
Despite widespread adoption of defensive measures, most IT professionals believe their DNS infrastructure is not secure enough. Enterprise Management Associates (EMA) recently published DDI Directions 2026, a market research report that explores enterprise strategies for DNS, DHCP, and IP address management (DDI). In that report, only 28% of DDI experts said they believe that their DNS infrastructure is completely secure.…
Fixing encryption isn’t enough. Quantum developments put focus on authentication
We are now entering the era of fault-tolerant quantum computing. The computers are getting better. The qubits are getting faster and more reliable, and there are more of them. NIST published its list of quantum-safe encryption algorithms, and now enterprises are racing to upgrade their encryption before Q-day, the quantum apocalypse that will make the previous generation of encryption protocols…

SSHStalker botnet brute-forces its way onto 7,000 Linux machines
A newly discovered botnet is compromising poorly-protected Linux servers by brute-forcing weak SSH password login authentication. Researchers at Canada-based Flare Systems, who discovered the botnet, got into its staging server and believe at least 7,000 servers had been compromised by the end of January, half of them in the US. The botnet’s weapons include exploits for unpatched Linux vulnerabilities going…
Intel says Google engineers spotted Xeon vulnerabilities
Intel said it was able to identify five vulnerabilities in the one of the most important confidential computing elements of its Xeon CPUs with help from Google’s cloud security team. The work was part of a five-month joint security review between Intel’s INT31 team (Intel’s offensive security research) and Google’s Cloud Security team. The partnership identified five vulnerabilities and 35…
