Invisible Pixels, Visible Risk: How TrojPix Rewrites the Air-Gap Assumption
A newly disclosed electromagnetic covert channel shows how a display can become a data-leak path, even when a system is supposed to be isolated.
Custom Backdoor Turns a Regional Intrusion Into a Critical Systems Problem
A reported campaign in Southeast Asia pairs a China-linked attribution with a new remote access tool, raising the stakes for government and utility networks.
TinyRCT and the Quiet Takeover of Critical Networks
A reported Southeast Asia espionage campaign spotlights a custom .NET backdoor, and the defensive problem it creates is bigger than any single intrusion.
The USB Trap Inside a Defense Network
A reported case involving counterfeit, malware-infected USB drives shows how a single removable device can become a trust-boundary problem in sensitive military environments.
Three High-Severity Fixes Put Mastodon Instance Operators on the Clock
A security update for the federated social network points to server-side flaws that could affect access control, confidentiality, and service availability.
curl’s Patch Wave Exposes a Familiar Weak Spot: Secrets and State
A large security release around curl highlights the same recurring danger in mature software: when credential handling and protocol state go wrong, the blast radius can spread far beyond a single crash.
Europe’s 6G Lab Is Teaching Networks to Spot Their Own Ghosts
Shield-6G is a pre-deployment security effort built around AI detection, digital twins, and honeypots, a sign that telecom defenses are being designed before 6G arrives at scale.
OT Vendors Turn to Multi-Layer Detection as Quantum Migration Creeps Into the Control Room
iOT365’s new model is a reminder that industrial security is no longer just about spotting malicious traffic - it is also about preparing for the long and messy move away from quantum-vulnerable cryptography.
The Callback That Slips Past the Front Door
Reverse shells turn a basic network rule on its head, showing why outbound behavior can matter more than inbound filtering alone.
The VPN Price Cut That Says More About Trust Than Savings
A 50% monthly discount and a 30-day refund window can make privacy software easier to try, but they do not simplify the security questions buyers should ask.
The Hidden Attack Surface Before Kickoff
A pre-2026 World Cup warning centers on exposed public data across parts of the event ecosystem, showing how large sponsorship networks can become security risk multipliers.
Two Years, One Pattern: The Quiet Cyber Pressure on Russian Maritime Campuses and Diplomats
An extended targeting pattern against maritime universities and diplomatic users highlights how high-trust institutions can become attractive cyber terrain even when attribution and intrusion methods remain unclear.
Inside the Sentence for an Oregon Government Network Intrusion
A 56-month federal sentence closes one criminal case, but the public record remains narrow: a Romanian national was punished for an intrusion involving an Oregon state government network and dozens of other U.S. victims.
The CDN Gap That DNS Never Saw Coming
A research-led bypass technique dubbed Underminr spotlights a stubborn weakness in DNS-only defenses: shared edge infrastructure can blur where a request appears to go and where it actually lands.
When the Car Becomes a Network, Security Must Follow the Route
Connected vehicles are no longer isolated products but distributed digital systems, and the real security question is increasingly about how data moves between cars, clouds, and third parties.
When Network Alerts Stop Behaving Like Static
Network Detection and Response is still fighting its old reputation for noisy alerts, but agentic AI is now being used by some teams to spot threats sooner, move through triage faster, and cut down false positives.
When Reputation Becomes a Cloak: The CDN Edge Trick Defenders Worry About
A technique described as Underminr points to a brittle trust problem in shared CDN environments, where domain-based filtering may not reflect the full routing path.
The Industrial Trapdoor: Why Weak Logins Put OT Networks in the Crosshairs
A familiar mix of exposed industrial systems and fragile authentication is turning critical infrastructure into a reachable target, even when no confirmed breach details are public.
Memcached Under Pressure: High-Severity Flaws Put Cache Data Back in the Crosshairs
Two high-severity vulnerabilities in Memcached highlight how a fast cache can become a sensitive exposure point when deployment boundaries, protocol choices, and patch levels are not tightly controlled.
Inside the Factory’s New Blind Spot: Private 5G Looks Efficient, Until the Risk Model Catches Up
Private 5G can turn a plant into a highly controlled wireless domain, but the same design choices that improve mobility and latency also create a more delicate security problem.
