The Hacker News | #1 Trusted Source for Cybersecurity News

The worst part is how normal these attacks look. A call from IT. A shared file. A trusted app. A simple request to click “Allow.” Why break in when someone might open the door? That idea runs through this edition. Attackers use real tools, fake login pages, old account links, and software guides that point to unsafe downloads. One wrong letter in a web address can be enough. There is also ransomware, stolen ID data, hidden attack servers, and weak settings that should have been fixed long ago. Here’s the full list. The threats change every week. Subscribe, and we’ll alert you when each new ThreatsDay Bulletin is out.

Cisco has released patches to address a critical security flaw affecting 10 Silicon One-based Nexus 9000 switches that could allow an unauthenticated, remote attacker to execute code as root, alongside an IOS XR hardening release bundling 7 umbrella CVEs, 2 of which are rated 9.8, with no workaround for any IOS XR version. The Nexus vulnerability, tracked as CVE-2026-20212 (CVSS score: 9.8), is a case of binding to an unrestricted IP address that leaves TCP ports 43210 and 43211 reachable in the default Layer 3 virtual routing and forwarding (VRF) instance. An attacker who can reach a switch's address on either port can connect directly to the service. Crafted input sent to that service is then executed as code with root privileges. An exploitation attempt can also crash the S1HAL process and reload the device. Cisco said it's not aware of any malicious use of the flaw as of its September 2 disclosure. It has published no fixed-release table and directs customers to its...

Cybersecurity researchers have disclosed details of a sophisticated Python-based Windows malware framework called BraZetsu that fuels an underground marketplace commercializing access to compromised hosts. "Unlike the standard infostealer model, BraZetsu is a comprehensive master toolkit that empowers Initial Access Brokers (IABs) by turning compromised systems into highly valuable commercial assets," Group-IB malware analysts Julio Guapo Menezes and Miguel Salazar said in a technical report. "The framework exhibits high operational maturity, utilizing a modular architecture and stealth techniques that allowed some samples to remain fully undetectable on VirusTotal at the time of analysis." BraZetsu is a portmanteau of "Brazil" and "Zetsu," a fictional character from the Japanese Manga series Naruto who is known to operate as a threat from the shadows. The naming is inspired by the fact that the initial access tool stealthily infiltrat...

Thomson Reuters disclosed on Wednesday that an unauthorized party obtained files from C-Track , the court case management platform sold by its West Publishing Corporation unit, in March 2026, affecting courts in 11 U.S. states, the U.S. Virgin Islands, and Ontario, Canada. West Publishing said it discovered the activity on June 30, 2026. A subset of court records could contain individuals' names, Social Security numbers, driver's license numbers, dates of birth, medical information, and health insurance information, the company said. The firm is offering potentially affected individuals 12 months of Experian IdentityWorks credit monitoring, with enrollment open until December 31, 2026, using a multi-use code published in the notice, and a hotline at 1-833-918-5294 that requires the engagement number B171847. In Canada, Thomson Reuters Canada Limited is offering 12 months of TransUnion myTrueIdentity monitoring with a call center scheduled to open on September 4. "...

An RMM phishing campaign initially associated with Canadian targeting due to its use of Canada Revenue Agency (CRA) tax forms as lures has turned out to be part of a broader campaign spanning 46 countries. Around 45% of observed activity was associated with the United States , making it the campaign's top geographic target. ANY.RUN research connected 601 cases to the wider operation, which uses fake documents to trick victims into installing legitimate remote monitoring and management (RMM) software. The attackers adapt their lures to different targets, using shipping and UPS communications, Adobe PDFs, tax notices, US Social Security Administration themes, invoices, and other documents. Rapidly rotated, disposable Vercel infrastructure makes the campaign harder to track and detect. US-First Threat with Daily Infrastructure Rotation Threat overview by ANY.RUN The campaign’s infrastructure changes significantly faster than its attack pattern. ANY.RUN researchers identifi...

Threat actors are leveraging the trusted Node.js JavaScript runtime in multiple cyber attacks as a way to deploy malicious payloads. According to a new report published by the Symantec Threat Hunter Team today, the attack method has been put to use in attacks targeting government departments, technology companies, and hotels since February 2026. "The technique's appeal is that node.exe (the binary that runs Node.js) is a legitimate, signed developer tool," the Broadcom-owned cybersecurity division said in a report shared with The Hacker News. "The attacker's malicious code lives in interpreted scripts rather than in a binary, making it less likely to trigger signature-based detection, while a registry Run key entry can relaunch the payload at every login." In one intrusion observed between March 23 and July 25, 2026, targeting an unspecified Asian technology company, attackers downloaded the official Node.js installer from nodejs[.]org and used the t...

In early August, GitGuardian researchers found that a recent Shai-Hulud infostealer worm variant had evolved to scan for credentials across 469 locations across developer environments , Continuous Integration/Continuous Deployment (CI/CD) tooling, cloud configurations, and even AI tool configs. Earlier variants of the infostealer worm only checked 189 paths. The jump says a lot. Attackers have stopped trying to break trust relationships and started using the credentials that already make those relationships work. Software supply chains have always depended on trust.  Developers trust package registries. Organizations trust maintainers. CI/CD systems trust the credentials and identities they're given. Applications trust the dependencies they pull down during a build.  Attackers realized they don't need to break any of that. They just needed to find where the credentials and standing privileges already sit. This is what is driving the current focus on software supply ...

The iPhone belonging to a member of Serbia's student protest movement was infected with NSO Group's Pegasus spyware , according to new findings from the Citizen Lab in collaboration with the SHARE Foundation. "Our analysis confirmed that an iMessage zero-click exploit was used to infect the device with NSO Group's Pegasus spyware," the Citizen Lab said . "We found high-confidence indicators of infection from a period across December 2025 – January 2026; however, this does not preclude the possibility of additional infections." It's assessed that the zero-click exploit used in the attack targeted Apple iMessage, and has been addressed by Apple with iOS 18.4.1 , which was released in April 2025. The discovery comes in the aftermath of Apple sending a new set of threat notifications to customers whom it suspected may have been targeted by mercenary spyware attacks. The alerts were sent to an unspecified number of users in 110 countries. In a...

The security researcher known as Chaotic Eclipse (aka INFINITE NIGHTMARE, MSNightmare, and Nightmare-Eclipse) has dropped a new zero-day dubbed FalconFlank , a privilege escalation flaw impacting Crowdstrike Falcon. "FalconFlank is a 0day privilege escalation that abuses the office malicious macros remediation in CrowdStrike Falcon Sensor," the researcher said in a GitHub README file, adding the cybersecurity company may already have detections for the flaw by now. "So if you want to test, you either have to add it to the exclusions or obfuscate the PoC and change the DLL load technique." The PoC, the researcher added, works in a fully updated Windows 11 25H2 machine or Windows Server 2025 with Crowdstrike Falcon. The Hacker News has contacted CrowdStrike for comment, and we will update the story if we hear back. The development comes days after Chaotic Eclipse released a PoC for another privilege escalation flaw impacting Kaspersky's endpoint securi...

The U.S. Cybersecurity and Infrastructure Security Agency (CISA) on Wednesday added seven security flaws to its Known Exploited Vulnerabilities ( KEV ) catalog after they landed in attackers' crosshairs. The vulnerabilities are as follows - CVE-2026-83548 (CVSS score: 10.0) - A server-side request forgery vulnerability in SonicWall SMA 1000 Appliances that could allow a remote unauthenticated attacker to gain unauthorized access to sensitive functionality and perform unauthorized operations.  CVE-2026-83549 (CVSS score: 7.8) - A post-authentication operating system command injection vulnerability in SonicWall SMA 1000 Appliances that could enable a remote authenticated attacker as administrator to execute arbitrary OS commands, resulting in remote code execution. CVE-2026-9586 (CVSS score: 9.3) - An SQL injection vulnerability in Sangoma Switchvox that could allow an unauthenticated remote attacker to execute arbitrary SQL statements against the backend PostgreSQL...

Google on Wednesday announced Gemini 3.8 Flash Cyber, which it described as its most capable cybersecurity model, and has made it available to a set of trusted defenders via a new initiative called the Fairwind Program . "The Fairwind Program gives high-priority defenders (like governments, healthcare providers, and telecommunications services) early access to advanced models that help them build better defenses, before new threats arrive," Google said . "So defenders have an early advantage, to help them protect vital infrastructure – which in turn protects people who rely on those systems." The tech giant said it's currently working with over 650 partners globally, including CrowdStrike, Datadog, Menlo Security, Palo Alto Networks, and Snowflake. The program is available to a group of Google Cloud customers, government agencies, and cybersecurity partners. The release of Gemini 3.8 Flash Cyber comes a little over a month after Google unveiled Gemini 3....

An active malware campaign is using bogus software-download websites to impersonate trusted vendors and distribute malicious installers. "The campaign has targeted users looking to download popular software and has resulted in compromises across multiple organizations and industries, primarily affecting China-based operations of multinational organizations and Chinese-speaking users," Microsoft said . The installers, once launched, deploy malware that's capable of setting up persistence, weakening security protections, and communicating with attacker-controlled infrastructure. The activity has resulted in victims spanning healthcare, manufacturing, gaming, technology, logistics, government, and education sectors. The Windows maker has assessed with moderate confidence that the campaign is consistent with a Chinese threat cluster dubbed Silver Fox (aka Yinhu), which has a track record of using spoofed vendor download pages to distribute Gh0st RAT and ValleyRAT (a...

Manifold Security has disclosed eight security flaws across seven command-line AI coding agents in which a repository's own Git configuration names a command that the agent runs on the developer's machine, four of them still unpatched at publication. The command executes as the user, outside the agent's sandbox and without an approval prompt, and exploitation requires the repository to arrive as files with its .git directory intact, which a shared archive, a shared drive, a sync folder, or a USB stick preserves, whereas an ordinary clone does not. Fixes have shipped for goose, Claude Code, and Cursor, while Hermes Agent, Qwen Code, Grok Build, and a second path in Claude Code were still executing repository-supplied commands when Manifold retested them on September 1. OpenAI published three CVEs of its own the same day covering the identical class in Codex, credited to three unrelated research groups. "The helper runs outside Codex's command sandbox and wi...

A Chinese-speaking cybercrime cluster known as Gambling Goblin has been observed installing malicious Apache modules on compromised web servers run by Brazilian government and educational institutions, and using them to divert visitors to attacker-controlled pages promoting online gambling and sports betting. Check Point Research said it has tracked the campaign since mid-2025. The modules reverse-proxy visitors to a set of phishing pages while the traffic still appears to originate from the legitimate domain. The site's own security headers are stripped, allowing the injected content to run freely. Those pages pose as trusted app stores including Google Play, Microsoft Store, and Amazon, and push online gambling and sports betting behind that facade. Check Point said the likely goal is search engine optimization (SEO) manipulation at scale, with compromised high-reputation domains, many of them Brazilian government sites, chained together to inflate search rankings. AN...

Virtualizor said hackers used a Border Gateway Protocol (BGP) hijack to divert Softaculous traffic. The hackers then used the diverted update traffic to deliver a malicious Virtualizor package to some installations. A hosting-provider account separately said 5 of its 34 checked Virtualizor hypervisors sustained root-level compromise. The incident window ran from approximately August 28 at 20:57 Coordinated Universal Time (UTC) to August 30 at 06:10 UTC. Virtualizor said every operator should check its servers because the company has no affected-version range or definitive list of installations that received the package. Virtualizor released Patch 9 with a Security Analyzer on September 1, but the vendor said cryptographic package signing remained future work. Operators should run the official scanner, rotate and restrict application programming interface (API) credentials, and audit each server for persistence and unauthorized access. "This affected a handful of servers rat...

Cybersecurity researchers have disclosed details of a new Android banking trojan called StreamRat that was promoted to Spanish-speaking users through a fake television-streaming campaign on Meta and can give operators near-complete control of infected devices. ThreatFabric said the campaign's advertisement focused on Spain and reached an estimated 570,950 Meta accounts in the European Union that saw it at least once, with totals for infected devices and confirmed victims remaining unreported. Device takeover requires the victim to grant a succession of controls after sideloading the Android Package (APK). Users should stop the installation when a streaming app requests system controls unrelated to streaming. "There is little doubt that StreamRat is a new and technically sophisticated threat, developed by individuals with prior experience in the Android malware ecosystem," ThreatFabric said in its  StreamRat analysis . ThreatFabric did not attribute the campaign t...
