Brain-inspired chip runs near absolute zero and could transform quantum computing

Scientists at the University of Hong Kong have created a remarkable new type of brain-inspired chip that can function just above absolute zero, one of the coldest environments imaginable. By using a standard silicon carbide transistor in a completely new way, the team made a single device behave like an energy-efficient neuron, firing electrical “spikes” similar to those in the human brain.

One-way quantum synchronization could make quantum computers more reliable

Scientists at RIKEN have proposed a new way to make quantum systems synchronize in only one direction—like a one-way street for sound particles known as phonons. The breakthrough combines two quantum effects to create a form of one-way quantum synchronization that remains surprisingly stable even when exposed to manufacturing flaws and environmental noise, two major obstacles that have long hindered real-world quantum technologies.

Cybercriminals are moving away from mass phishing campaigns

Phishing activity declined by roughly 20% in both 2024 and 2025, according to research from Zscaler’s ThreatLabz team. The drop followed years of growth that pushed phishing activity above 2 billion hits in 2023. “Phishing volume measured by blocked emails is no longer a reliable proxy for phishing risk.” Researchers found greater use of targeted phishing campaigns designed to resemble routine business communications. The services sector recorded a 65.5% year-over-year increase in phishing activity, making … More → The post Cybercriminals are moving away from mass phishing campaigns appeared first on Help Net Security.

Authorities dismantle crypto laundering service that moved €336 million for cybercriminals

An international law enforcement operation has dismantled a cryptocurrency laundering service linked to ransomware groups and other cybercriminals that processed more than €336 million in illicit funds. The domain seizure notice (Source: Europol) Europol said the service, known as AudiA6, is suspected of laundering cryptocurrency obtained through ransomware attacks and other forms of cybercrime between 2022 and 2025. “The suspects behind ‘AudiA6’ are also believed to have administered the dark web cybercrime forum ‘Dark2Web’, a … More → The post Authorities dismantle crypto laundering service that moved €336 million for cybercriminals appeared first on Help Net Security.

Comcast Business SecurityEdge Preferred strengthens security for small businesses

Comcast Business announced SecurityEdge Preferred, its most advanced network-native cybersecurity solution for small businesses. Because SecurityEdge Preferred is built directly into the Comcast Business network, security can be activated in minutes without deploying additional hardware, managing multiple vendors, or maintaining complex security tools. Rather than adding another layer on top of existing infrastructure, it lives inside the connectivity small businesses already rely on – intercepting threats at the network edge, the moment traffic enters or … More → The post Comcast Business SecurityEdge Preferred strengthens security for small businesses appeared first on Help Net Security.

How to use NIST and ISO frameworks to govern AI agents

Security leaders no longer need convincing that AI agents introduce risk. What’s missing is how to govern them once they move into production and begin operating autonomously across enterprise environments. AI agents already read sensitive documents, invoke internal APIs, trigger workflows, and make decisions that still require human judgment. From a security perspective, the most important shift is not their intelligence, but their behavior and intent, since they carry delegated authority, operate autonomously, and often … More → The post How to use NIST and ISO frameworks to govern AI agents appeared first on Help Net Security.

The assembly line behind 1.5 million malicious domains

Attackers registered roughly 1.5 million malicious domains during the first five months of 2026. The registration patterns resemble industrial output. Most of the domains were created by attackers, put to use within weeks, and concentrated among a small set of registrars, top-level domains, and hosting providers. New research examined more than 1.5 million unique domains flagged on VirusTotal between January and May 2026. Each domain was flagged by at least five independent VirusTotal scanning engines … More → The post The assembly line behind 1.5 million malicious domains appeared first on Help Net Security.

AI sovereignty makes data centers strategic targets for cyber operations

Data centers built for frontier AI draw hundreds of megawatts of electricity and large volumes of cooling water from fixed locations with known addresses. Each one concentrates tens of thousands of graphics processors, liquid cooling systems, and high-density power equipment inside a single building. This physical footprint turns a nation’s AI capability into something an adversary can locate, measure, and degrade. Mechanisms determining AI sovereignty at the micro, meso, and macro levels AI sovereignty is … More → The post AI sovereignty makes data centers strategic targets for cyber operations appeared first on Help Net Security.
