Dutch intelligence agencies have revealed an extensive cyber campaign by Russian state-backed hackers aimed at infiltrating Signal and WhatsApp accounts of high-profile individuals worldwide. The Military Intelligence and Security Service (MIVD) and General Intelligence and Security Service (AIVD) describe the effort as large-scale and ongoing, exploiting user vulnerabilities rather than app flaws. The operation focuses on government officials, military personnel, and civil servants, with Du

North Korea's state-sponsored Lazarus Group has added yet another ransomware strain to its arsenal. New research from the Symantec and Carbon Black Threat Hunter Team reveals that the group has been observed deploying Medusa ransomware in an attack against an unnamed entity in the Middle East and, separately, attempting an unsuccessful breach of a healthcare organization in the United States. The findings represent a notable evolution in Lazarus's tactics. The group has previously been linked t

In the modern corporate landscape, cybersecurity has long been viewed as a necessary expense a "grudge purchase" designed to prevent disaster. A groundbreaking study presented at the 59th Hawaii International Conference on System Sciences (HICSS) | 2026 provides the first empirical evidence that cybersecurity is a driver of financial success. The paper, titled "Effects of Cybersecurity Readiness on Firm Performance: Evidence from Conference Calls," introduces a novel way to measure a company's
FortiGuard Labs recently observed several targeted phishing campaigns in Taiwan that use themes designed to exploit local business processes. These campaigns disseminate Winos 4.0 (ValleyRat) and subsequent malicious plugins through weaponized attachments or embedded links. The lures mimic official communications, such as tax audit notifications, tax filing software installers, and cloud-based e-invoice downloads.

A new security feature rolled out to select models of the latest iPhones and iPads will make it more difficult for law enforcement, spies, and malicious hackers to obtain a person’s precise location data from their phone provider. According to Apple, the new feature, when enabled, limits the precision of location data that iPhones and cellular-enabled iPads share with the customer’s cell carrier. Sharing a less precise location, such as the general neighborhood rather than a street address, wi
A new analysis by researchers at CyberArk has detailed a significant research effort revealing operational details of a StealC malware operator by exploiting a vulnerability in the malware's leaked web panel. The recent findings demonstrate how poor security practices within criminal infrastructure can be turned against threat actors. StealC is information-stealing malware operating under a Malware-as-a-Service (MaaS) model since early 2023. It enables customers to steal passwords, session co
