The Truth About VPNs and the Rise of Quantum Decryption

During Risk Assessments, and working with clients, I routinely run into situations where users think everything they are doing on their laptop is confidential because they are using a VPN. After some discussion, it often turns out that they are using a browser-based VPN. That is a big problem. When users and IT think they have protection, and they are acting as if they do, this opens up a very serious gap. READ MORE...

Clorox is suing its service desk provider, Cognizant, for $380 million in a California state court, alleging the IT support crew "enabled a cybercriminal to gain a foothold in Clorox's network" by handing over staffers' passwords to attackers after they simply requested them. Clorox filed a complaint yesterday alleging breach of contract and negligence, among other things, and claimed Cognizant's "failures" ultimately led to a "catastrophic cyberattack" against the bleach maker in 2023.

3 China Nation-State Actors Target SharePoint Bugs

Ports are getting smarter and more hackable

A new policy brief from NATO's Cooperative Cyber Defence Centre of Excellence (CCDCOE) warns that critical port infrastructure, responsible for 80 percent of global trade, is increasingly under attack by threat actors tied to Russia, Iran, and China. These ports are essential to national economies and serve as key hubs in NATO's logistics network. Many remain under civilian control with limited integration into military cybersecurity strategies, leaving serious gaps in defence coordination. READ MORE...

Dwindling federal cyber support for critical infrastructure raises alarms

As the U.S. government prepares to decrease its cybersecurity support for critical infrastructure operators, the organizations that defend those networks are preparing for more vulnerabilities, more hacks and more damage. President Donald Trump's quest to reduce the federal role in infrastructure cyber resilience will exacerbate already alarming cybersecurity weaknesses throughout the nation's hospitals, ports, railways and other vital systems, according to industry leaders and cyber experts.

Humans can be tracked with unique 'fingerprint' based on how their bodies block Wi-Fi signals

Researchers in Italy have developed a way to create a biometric identifier for people based on the way the human body interferes with Wi-Fi signal propagation. The scientists claim this identifier, a pattern derived from Wi-Fi Channel State Information, can re-identify a person in other locations most of the time when a Wi-Fi signal can be measured. Observers could therefore track a person as they pass through signals sent by different Wi-Fi networks - even if they're not carrying a phone. READ MORE...
