Attackers are using stolen connection keys exposed in a TeamUpdraft security breach to install malicious plugins on affected WordPress sites and establish persistent access. Sites already compromised may remain at risk even after the exposed credentials are revoked. The attacks…
Private keys associated with eight intermediate certificate authorities operated by Indian digital trust provider eMudhra have been compromised, potentially allowing attackers to forge trusted certificates and impersonate websites or services, according to Google and Mozilla.…
Exploits y PoCVulnerabilidades
Frontier AI advancements have created a world where exploitation outpaces defense. The average enterprise takes 32 to 43 days to patch, but the mean time to exploit a vulnerability is 10 hours. This asymmetry creates questions around how enterprises can trust autonomous AI to…

Security researchers have found a critical flaw in the Linux kernel’s networking stack that can let attackers escape a KVM virtual machine and execute code on the host system. The weakness could also potentially let attackers compromise systems running other Linux-based…
On the night of 11 October, someone remotely put the cold cases of several hundred French supermarkets into defrost. At Intermarché and Netto stores, fridges and freezers warmed to around 50°C and stayed there for about six hours, according to Les Mousquetaires, which expects…
Quantum-resistant cryptography presents security leaders with various challenges, but CISOs in industries dependent on IoT and operational technology (OT) devices may face a particularly difficult journey to quantum readiness, especially if sensitive information that must remain…
F5 is once again disclosing cybersecurity flaws in its core offerings. The app delivery and security provider has released out-of-band (OOB) security patches that address multiple flaws in NGINX, its high-performance software that controls digital traffic for websites. These…
Microsoft and Nvidia are urging enterprises to assess the security of open-weight AI models throughout deployment, warning that changes to model weights and configurations can weaken safeguards even when a model retains its ability to perform assigned tasks. In a joint paper…

A chain of vulnerabilities in Google’s Chrome browser could have enabled researchers to take control of one billion Windows machines worldwide — and it cost them just $40,000 in AI compute time to discover it. Researchers at Xbow USA worked for six days on developing the…
Bank of America has had to spend big on IT in response to an AI security audit and findings that its anti-money-laundering (AML) controls were lacking. The bank was fined a whopping $1.2 billion for money laundering offences this week, after banking authorities identified a lax…
The Linux kernel’s networking stack was found vulnerable to a guest-to-host escape attack, in which an attacker operating inside a virtual machine (VM) could cross the isolation boundary and access the underlying host. Dubbed PwnEscape and tracked as CVE-2026-99999, a flaw…
