The Hacker News | #1 Trusted Source for Cybersecurity News — Index Page

Monday opens with a trust problem. A mail server flaw is under active use. A network control system was targeted. Trusted packages were poisoned. A fake model page pushed a stealer. Then came the familiar ransom claim: the data was returned and deleted. The pattern is clear. One weak dependency can leak keys. One leaked key can open cloud access. One cloud foothold can become a production incident. AI is speeding up vulnerability discovery, attackers are moving quickly, and old exposure still keeps paying off. Patch the quiet risks first. Let’s get into it. ⚡ Threat of the Week On-Prem Microsoft Exchange Server Exploited in the Wild —Microsoft disclosed a security vulnerability impacting on-premise versions of Exchange Server, which has come under active exploitation in the wild. The vulnerability, tracked as CVE-2026-42897 (CVSS score: 8.1), has been described as a spoofing bug stemming from a cross-site scripting flaw. An anonymous researcher has been credited with discovering ...

What happens when a phishing email looks clean enough to pass through security, but dangerous enough to expose the business after one click? That is the gap many SOCs still struggle with: the attacks that leave teams unsure what was exposed, who else was targeted, and how far the risk has spread. Early phishing detection closes that gap. It helps teams move from uncertainty to evidence faster, reduce response delays, and stop one missed link from turning into account exposure, remote access, or operational disruption. Why Phishing Creates Bigger Risk for Security Leaders Now Phishing has become harder to manage because it no longer creates one clear, easy-to-contain event. A single click can turn into identity exposure, remote access, data access, or a wider investigation before the team has a clear picture. What makes it a bigger concern now: Puts identity at the center of the attack: Stolen credentials can expose email, SaaS apps, cloud platforms, and internal systems. Weak...

Supply chain attackers are not only trying to slip malicious code into trusted software. They are trying to steal the access that makes trusted software possible. Recently, three separate campaigns hit npm, PyPI, and Docker Hub in a 48-hour window, and all three targeted secrets from developer environments and CI/CD pipelines, including API keys, cloud credentials, SSH keys, and tokens. This is an ongoing concern and is self-propagating, as seen in attacks like the "mini Shai Hulud" campaigns.  That pattern should change how security teams think about the software supply chain. Traditionally, security focused on shared systems like source code repositories, CI/CD platforms, artifact registries, package managers, and cloud environments. The goal was to protect production workloads and data. We absolutely still need to focus on these areas, but it is an incomplete picture.  Modern software delivery begins before code reaches Git. It begins on the developer workstation, wher...

Ivanti, Fortinet, n8n, SAP, and VMware have released security fixes for various vulnerabilities that could be exploited by bad actors to bypass authentication and execute arbitrary code. Topping the list is a critical flaw impacting Ivanti Xtraction (CVE-2026-8043, CVSS score: 9.6) that could be exploited to achieve information disclosure or client-side attacks. "External control of a file name in Ivanti Xtraction before version 2026.2 allows a remote authenticated attacker to read sensitive files and write arbitrary HTML files to a web directory, leading to information disclosure and possible client-side attacks," Ivanti said in an advisory. Fortinet published advisories for two critical shortcomings affecting FortiAuthenticator and FortiSandbox, FortiSandbox Cloud, and FortiSandbox PaaS that could result in code execution - CVE-2026-44277 (CVSS score: 9.1) - An improper access control vulnerability in FortiAuthenticator that may allow an unauthenticated attacker to...

Chaotic Eclipse, the security researcher behind the recently disclosed Windows flaws, YellowKey and GreenPlasma , has released a proof-of-concept (PoC) for a Windows privilege escalation zero-day flaw that grants attackers SYSTEM privileges on fully patched Windows systems. Codenamed MiniPlasma , the vulnerability impacts "cldflt.sys," which refers to the Windows Cloud Files Mini Filter Driver, and resides in a routine named "HsmOsBlockPlaceholderAccess." It was originally reported to Microsoft by Google Project Zero researcher James Forshaw in September 2020. Although it was assumed that the shortcoming was fixed by Microsoft in December 2020 as part of CVE-2020-17103 , Chaotic Eclipse said further investigation has uncovered that the "exact same issue [...] is actually still present, unpatched." "I'm unsure if Microsoft just never patched the issue or the patch was silently rolled back at some point for unknown reasons. The original PoC by...

Cybersecurity researchers have discovered four new npm packages containing information-stealing malware, one of which is a clone of the Shai-Hulud worm open-sourced by TeamPCP . The list of identified packages is below - chalk-tempalte (825 Downloads) @deadcode09284814/axios-util (284 Downloads) axois-utils (963 Downloads) color-style-utils (934 Downloads) "One of the packages (chalk-tempalte) contains a direct clone of the Shai-Hulud source code that TeamPCP leaked last week, probably inspired as part of the supply chain attack competition that was published in BreachForums not long after," OX Security's Moshe Siman Tov Bustan said. Interestingly, the malicious payloads embedded into the four npm packages are different, despite them being published by the same npm user, " deadcode09284814 ." As of writing, the four libraries are still available for download from npm. An analysis of the packages has revealed that "axois-utils" is designed ...
