Cybersecurity researchers have discovered a set of trojanized npm packages that masquerade as working calendar and streak utilities but are engineered to stealthily deliver an artificial intelligence (AI)-powered Linux implant dubbed RedC2 4.0. "When the module loads, it locates the bundled binary, marks it executable, and launches it as a detached background process," TrendAI, Trend Micro's enterprise cybersecurity business, said in a report published Thursday. "No install hook function call is needed; a single import anywhere in the dependency graph, even a transitive one, is enough to execute the payload." The list of identified packages is below - streak-metrics-math@1.0.0,1.0.1 kit-map-vim@1.0.0 streak-map-cache@1.0.0 streak-map-kit@1.0.0 map-streak-kit@1.0.0 streak-cache-map@1.0.0 streak-calc-metrics@1.0.0 streak-calc-math@1.0.0 streak-math-abz@1.0.0 streak-metricsaz@1.0.0 streak-math-metrics@1.0.0 streak-metrica...

Check Point Research has disclosed a technique that uses Microsoft Defender's own legitimately signed boot-time remediation driver to perform arbitrary kernel-level file and registry operations on Windows systems ranging from Windows 7 through Windows 11 25H2, with no software flaw exploited and no driver imported from outside the machine. The driver, BTR.sys (Boot Time Removal Tool), is a required Windows component, which means it cannot be added to Microsoft's Vulnerable Driver Blocklist or blocked via Windows Defender Application Control (WDAC) without disrupting Defender itself. Jiří Vinopal, a threat researcher and reverse engineer at Check Point Research, presented the findings as a main-stage briefing at Black Hat USA 2026 and DEF CON 34 in Las Vegas and published the accompanying research paper alongside a proof-of-concept tool, BTR_CLI, on August 20, 2026. Check Point Research said it found no evidence the technique has been used in real-world attacks. "Dur...

Cybersecurity researchers have flagged a new malware family that's specifically designed to infect Android-based vehicle head unit firmware developed by DoFun. Kaspersky, which discovered the threat in June 2026, said the end goal of the malware is to serve a multi-stage downloader to enable ad fraud and creation of a proxy botnet. "The malware spread through the built-in updaters of Android-based automotive head unit firmware," security researcher Dmitry Kalinin said. "This is the first documented case of malware found on a car head unit with an infection chain specific to that type of device." The activity has been attributed with high confidence to the MoYu Group , which was outed by the HUMAN Satori Threat Intelligence and Research team last year as part of a broader ad fraud and residential proxy scheme dubbed BADBOX. In July 2025, Google filed a lawsuit against 25 unnamed individuals or entities in China for allegedly operating the BADBOX botnet a...

Artificial Intelligence (AI) has become one of this decade's defining technologies. From healthcare and finance to manufacturing and education, organizations increasingly rely on AI to automate repetitive tasks, uncover patterns hidden within large datasets, and support faster decision-making. Cybersecurity has experienced a similar transformation. While attackers employ AI to automate cyberattacks and accelerate vulnerability discovery, defenders are adopting AI to improve threat detection and enhance incident response. Security Operations Centers (SOCs) receive a high volume of alerts from endpoints, cloud workloads, network devices, identity providers, and business applications. Although SIEM and XDR platforms provide visibility into these environments, analysts often spend considerable time correlating alerts, searching documentation, and determining the next investigative steps. AI offers a practical way to augment analysts by providing contextual explanations, summarizing ...

Cisco has published another round of security updates for Crosswork platforms and Secure Workload Software as part of a continued comprehensive internal security review. Four of the security vulnerabilities affect Crosswork Data Gateway, Crosswork Network Controller, and Crosswork Planning, regardless of the device configuration. A brief description of each of the flaws is below - CVE-2026-20030 (CVSS score: 10.0) - An SQL injection vulnerability CVE-2026-20357 (CVSS score: 10.0) - A missing authentication for critical function vulnerability CVE-2026-20358 (CVSS score: 10.0) - An external control of file system vulnerability CVE-2026-20359 (CVSS score: 9.9) - An insufficiently protected credentials vulnerability The issues affect Cisco Crosswork Release version 7.2.1 and earlier, and have been addressed in version 7.2.1-SP. Cisco has also released fixes to remediate five vulnerabilities affecting Cisco Secure Workload, including Software-as-a-Service (SaaS) a...
