As cyber threats get smarter, companies are using Zero Trust Security Models to keep their data safe. This way of thinking means "never trust, always verify."
Linux 'io_uring' security blindspot allows stealthy rootkit attacks
A significant security gap in Linux runtime security caused by the 'io_uring' interface allows rootkits to operate undetected on systems while bypassing advanced Enterprise security software.
Operation SyncHole: Lazarus APT goes back to the well
Kaspersky GReAT experts uncovered a new campaign by Lazarus APT that exploits vulnerabilities in South Korean software products and uses a watering hole approach.
Attackers hit security device defects hard in 2024 | CyberScoop
Mandiant said exploits were the most common initial access vector last year, linking software defects to 1 in 3 attacks. The most commonly exploited vulnerabilities affected network edge devices.
A whistleblower at the National Labor Relations Board (NLRB) alleged last week that denizens of Elon Musk's Department of Government Efficiency (DOGE) siphoned gigabytes of data from the agency's sensitive case files in early March. The whistleblower said accounts created…
Russian army targeted by new Android malware hidden in mapping app
A new Android malware has been discovered hidden inside trojanized versions of the Alpine Quest mapping app, which is reportedly used by Russian soldiers as part of war zone operational planning.
Millions impacted by data breaches at Blue Shield of California, mammography service and more
Blue Shield of California said an improper Google Analytics configuration exposed the data of more than 4.5 million people, while state regulators recently received more than a dozen other reports involving healthcare-related organizations.
Cloudflare: Government-backed internet shutdowns plummet to zero in first quarter
Governments around the world have appeared to ease off from using internet shutdowns to silence protesters and control access to information, according to new data from internet infrastructure company Cloudflare.
Understanding the threat landscape for Kubernetes and containerized assets
The dynamic nature of containers can make it challenging for security teams to detect runtime anomalies or pinpoint the source of a security incident, presenting an opportunity for attackers to stay undetected. Microsoft Threat Intelligence has observed threat actors taking advantage of unsecured workload identities to gain access to resources, including containerized environments. Microsoft data […]
Regulating AI Behavior with a Hypervisor - Schneier on Security
Interesting research: “Guillotine: Hypervisors for Isolating Malicious AIs.” Abstract:As AI models become more embedded in critical sectors like finance, healthcare, and the military, their inscrutable behavior poses ever-greater risks to society. To mitigate this risk, we propose Guillotine, a hypervisor architecture for sandboxing powerful AI models—models that, by accident or malice, can generate existential threats to humanity. Although Guillotine borrows some well-known virtualization techniques, Guillotine must also introduce fundamentally new isolation mechanisms to handle the unique threat model posed by existential-risk AIs. For example, a rogue AI may try to introspect upon hypervisor software or the underlying hardware substrate to enable later subversion of that control plane; thus, a Guillotine hypervisor requires careful co-design of the hypervisor software and the CPUs, RAM, NIC, and storage devices that support the hypervisor software, to thwart side channel leakage and more generally eliminate mechanisms for AI to exploit reflection-based vulnerabilities. Beyond such isolation at the software, network, and microarchitectural layers, a Guillotine hypervisor must also provide physical fail-safes more commonly associated with nuclear power plants, avionic platforms, and other types of mission critical systems. Physical fail-safes, e.g., involving electromechanical disconnection of network cables, or the flooding of a datacenter which holds a rogue AI, provide defense in depth if software, network, and microarchitectural isolation is compromised and a rogue AI must be temporarily shut down or permanently destroyed. ...
Ransomware groups test new business models to hit more victims, increase profits
The DragonForce and Anubis groups are attempting to entice hackers to come and work with them by adopting affiliate models that would increase the volume of incidents their services can be used in.
