Cybersecurity researchers have disclosed details of a new attack method dubbed Reprompt that could allow bad actors to exfiltrate sensitive data from artificial intelligence (AI) chatbots like Microsoft Copilot in a single click, while bypassing enterprise security controls entirely. "Only a single click on a legitimate Microsoft link is required to compromise victims," Varonis security researcher Dolev Taler said in a report published Wednesday. "No plugins, no user interaction with Copilot." "The attacker maintains control even when the Copilot chat is closed, allowing the victim's session to be silently exfiltrated with no interaction beyond that first click." Following responsible disclosure, Microsoft has addressed the security issue. The attack does not affect enterprise customers using Microsoft 365 Copilot. At a high level, Reprompt employs three techniques to achieve a data‑exfiltration chain - Using the "q" URL parameter i...

The internet never stays quiet. Every week, new hacks, scams, and security problems show up somewhere. This week's stories show how fast attackers change their tricks, how small mistakes turn into big risks, and how the same old tools keep finding new ways to break in. Read on to catch up before the next wave hits. Unauthenticated RCE risk Security Flaw in Redis A high-severity security flaw has been disclosed in Redis (CVE-2025-62507, CVSS score: 8.8) that could potentially lead to remote code execution by means of a stack buffer overflow. It was fixed in version 8.3.2. JFrog's analysis of the flaw has revealed that the vulnerability is triggered when using the new Redis 8.2 XACKDEL command, which was introduced to simplify and optimize stream cleanup. Specifically, it resides in the implementation of xackdelCommand(), a function responsible for parsing and processing the list of stream IDs supplied by the user. "The core ...

It's 2026, yet many SOCs are still operating the way they did years ago, using tools and processes designed for a very different threat landscape. Given the growth in volumes and complexity of cyber threats, outdated practices no longer fully support analysts' needs, staggering investigations and incident response. Below are four limiting habits that may be preventing your SOC from evolving at the pace of adversaries, and insights into what forward-looking teams are doing instead to achieve enterprise-grade incident response this year. 1. Manual Review of Suspicious Samples Despite advances in security tools, many analysts still rely heavily on manual validation and analysis. This approach creates friction on every step, from processing samples to switching between tools and manually correlating the findings.  Manually dependent workflows are often the root cause of alert fatigue and delayed prioritization, subsequently slowing down response. These challenges are especially re...

Not long ago, AI agents were harmless. They wrote snippets of code. They answered questions. They helped individuals move a little faster. Then organizations got ambitious. Instead of personal copilots, companies started deploying shared organizational AI agents - agents embedded into HR, IT, engineering, customer support, and operations. Agents that don't just suggest, but act. Agents that touch real systems, change real configurations, and move real data: An HR agent who provisions and deprovisions access across IAM, SaaS apps, VPNs, and cloud platforms. A change management agent that approves requests, updates production configs, logs actions in ServiceNow, and updates Confluence. A support agent that pulls customer data from CRM, checks billing status, triggers backend fixes, and updates tickets automatically. These agents warrant deliberate control and oversight. They're now part of our operational infrastructure. And to make them useful, we made them powerful ...

This week made one thing clear: small oversights can spiral fast. Tools meant to save time and reduce friction turned into easy entry points once basic safeguards were ignored. Attackers didn't need novel tricks. They used what was already exposed and moved in without resistance. Scale amplified the damage. A single weak configuration rippled out to millions. A repeatable flaw worked again and again. Phishing crept into apps people rely on daily, while malware blended into routine system behavior. Different victims, same playbook: look normal, move quickly, spread before alarms go off. For defenders, the pressure keeps rising. Vulnerabilities are exploited almost as soon as they surface. Claims and counterclaims appear before the facts settle. Criminal groups adapt faster each cycle. The stories that follow show where things failed—and why those failures matter going forward. ⚡ Threat of the Week Maximum Severity Security Flaw Disclosed in n8n — A maximum-severity vulnerability ...

A new wave of GoBruteforcer attacks has targeted databases of cryptocurrency and blockchain projects to co-opt them into a botnet that's capable of brute-forcing user passwords for services such as FTP, MySQL, PostgreSQL, and phpMyAdmin on Linux servers. "The current wave of campaigns is driven by two factors: the mass reuse of AI-generated server deployment examples that propagate common usernames and weak defaults, and the persistence of legacy web stacks such as XAMPP that expose FTP and admin interfaces with minimal hardening," Check Point Research said in an analysis published last week. GoBruteforcer, also called GoBrut, was first documented by Palo Alto Networks Unit 42 in March 2023, documenting its ability to target Unix-like platforms running x86, x64, and ARM architectures to deploy an Internet Relay Chat (IRC) bot and a web shell for remote access, along with fetching a brute-force module to scan for vulnerable systems and expand the botnet's reach. ...

Cybersecurity researchers have shed light on two service providers that supply online criminal networks with the necessary tools and infrastructure to fuel the pig butchering-as-a-service (PBaaS) economy. At least since 2016, Chinese-speaking criminal groups have erected industrial-scale scam centers across Southeast Asia, creating special economic zones that are devoted to fraudulent investment and impersonation operations. These compounds are host to thousands of people who are lured with the promise of high-paying jobs, only to have their passports and be forced to conduct scams under the threat of violence. INTERPOL has characterized these networks as human trafficking-fuelled fraud on an industrial scale. One of the crucial drivers of the pig butchering (aka romance baiting) scams is service providers who supply the networks with all the tools to run and manage social engineering operations, as well as swiftly launder stolen funds and cryptocurrencies and move ill-gotten p...

The Iranian threat actor known as MuddyWater has been attributed to a spear-phishing campaign targeting diplomatic, maritime, financial, and telecom entities in the Middle East with a Rust-based implant codenamed RustyWater . "The campaign uses icon spoofing and malicious Word documents to deliver Rust based implants capable of asynchronous C2, anti-analysis, registry persistence, and modular post-compromise capability expansion," CloudSEK resetter Prajwal Awasthi said in a report published this week. The latest development reflects continued evolution of MuddyWater's tradecraft, which has gradually-but-steadily reduced its reliance on legitimate remote access software as a post-exploitation tool in favor of a diverse custom malware arsenal comprising tools like Phoenix, UDPGangster , BugSleep (aka MuddyRot), and MuddyViper . Also tracked as Mango Sandstorm, Static Kitten, and TA450, the hacking group is assessed to be affiliated with Iran's Ministry of Intelli...

The U.S. Cybersecurity and Infrastructure Security Agency (CISA) on Thursday said it's retiring 10 emergency directives (Eds) that were issued between 2019 and 2024. The list of the directives now considered closed is as follows - ED 19-01: Mitigate DNS Infrastructure Tampering ED 20-02: Mitigate Windows Vulnerabilities from January 2020 Patch Tuesday ED 20-03: Mitigate Windows DNS Server Vulnerability from July 2020 Patch Tuesday   ED 20-04: Mitigate Netlogon Elevation of Privilege Vulnerability from August 2020 Patch Tuesday ED 21-01: Mitigate SolarWinds Orion Code Compromise ED 21-02: Mitigate Microsoft Exchange On-Premises Product Vulnerabilities ED 21-03: Mitigate Pulse Connect Secure Product Vulnerabilities   ED 21-04: Mitigate Windows Print Spooler Service Vulnerability   ED 22-03: Mitigate VMware Vulnerabilities ED 24-02: Mitigating the Significant Risk from Nation-State Compromise of Microsoft Corporate Email System   Stating that these directives were iss...

The U.S. Federal Bureau of Investigation (FBI) on Thursday released an advisory warning of North Korean state-sponsored threat actors leveraging malicious QR codes in spear-phishing campaigns targeting entities in the country. "As of 2025, Kimsuky actors have targeted think tanks, academic institutions, and both U.S. and foreign government entities with embedded malicious Quick Response (QR) codes in spear-phishing campaigns," the FBI said in the flash alert. "This type of spear-phishing attack is referred to as quishing." The use of QR codes for phishing is a tactic that forces victims to shift from a machine that's secured by enterprise policies to a mobile device that may not offer the same level of protection, effectively allowing threat actors to bypass traditional defenses. Kimsuky, also tracked as APT43, Black Banshee, Emerald Sleet, Springtail, TA427, and Velvet Chollima, is a threat group that's assessed to be affiliated with North Korea's...

Honeypot Traps Hackers Hackers Fall for Resecurity's Honeypot Cybersecurity company Resecurity revealed that it deliberately lured threat actors who claimed to be associated with Scattered LAPSUS$ Hunters ( SLH ) into a trap, after the group claimed on Telegram that it had hacked the company and stolen internal and client data. The company said it set up a honeytrap account populated with fake data designed to resemble real-world business data and planted a fake account on an underground marketplace for compromised credentials after it uncovered a threat actor attempting to conduct malicious activity targeting its resou...

Cybersecurity researchers have discovered three malicious npm packages that are designed to deliver a previously undocumented malware called NodeCordRAT . The names of the packages, all of which were taken down as of November 2025, are listed below. They were uploaded by a user named "wenmoonx." bitcoin-main-lib (2,300 Downloads) bitcoin-lib-js (193 Downloads) bip40 (970 Downloads) "The bitcoin-main-lib and bitcoin-lib-js packages execute a postinstall.cjs script during installation, which installs bip40, the package that contains the malicious payload," Zscaler ThreatLabz researchers Satyam Singh and Lakhan Parashar said. "This final payload, named NodeCordRAT by ThreatLabz, is a remote access trojan (RAT) with data-stealing capabilities." NodeCordRAT gets its name from the use of npm as a propagation vector and Discord servers for command-and-control (C2) communications. The malware is equipped to steal Google Chrome credentials, API tokens,...

Security teams are still catching malware. The problem is what they're not catching. More attacks today don't arrive as files. They don't drop binaries. They don't trigger classic alerts. Instead, they run quietly through tools that already exist inside the environment — scripts, remote access, browsers, and developer workflows. That shift is creating a blind spot. Join us for a deep-dive technical session with the Zscaler Internet Access team. They will reveal how to unmask "hidden-in-plain-sight" tactics, why traditional defenses fall short, and exactly what needs to change. Secure your spot for the live session ➜ In this session, experts will cover: "Living off the Land" Attacks: These use trusted system tools like PowerShell, WMI, or remote desktop. File-based detection often sees nothing wrong because, technically, nothing new was installed. Fileless "Last Mile" Reassembly Attacks: Obfuscated HTML and JavaScript can e...

Cybersecurity researchers have disclosed details of yet another maximum-severity security flaw in n8n , a popular workflow automation platform, that allows an unauthenticated remote attacker to gain complete control over susceptible instances. The vulnerability, tracked as CVE-2026-21858 (CVSS score: 10.0), has been codenamed Ni8mare by Cyera Research Labs. Security researcher Dor Attias has been acknowledged for discovering and reporting the flaw on November 9, 2025. "A vulnerability in n8n allows an attacker to access files on the underlying server through execution of certain form-based workflows," n8n said in an advisory published today. "A vulnerable workflow could grant access to an unauthenticated remote attacker. This could result in exposure of sensitive information stored on the system and may enable further compromise depending on deployment configuration and workflow usage." With the latest development, n8n has disclosed four critical vulnerabili...

Open-source workflow automation platform n8n has warned of a maximum-severity security flaw that, if successfully exploited, could result in authenticated remote code execution (RCE). The vulnerability, which has been assigned the CVE identifier CVE-2026-21877 , is rated 10.0 on the CVSS scoring system. "Under certain conditions, an authenticated user may be able to cause untrusted code to be executed by the n8n service," n8n said in an advisory released Tuesday. "This could result in full compromise of the affected instance." The maintainers said both self-hosted deployments and n8n Cloud instances are impacted. The issue impacts the following versions - >= 0.123.0 < 1.121.3 It has been addressed in version 1.121.3, which was released in November 2025. Security researcher Théo Lelasseux (@ theolelasseux ) has been credited with discovering and reporting the flaw. Users are advised to upgrade to this version or later to completely address the vuln...

Non-human employees are becoming the future of cybersecurity, and enterprises need to prepare accordingly. As organizations scale Artificial Intelligence (AI) and cloud automation, there is exponential growth in Non-Human Identities (NHIs), including bots, AI agents, service accounts and automation scripts. In fact, 51% of respondents in ConductorOne's 2025 Future of Identity Security Report said the security of NHIs is now just as important as that of human accounts. Yet, despite their presence in modern organizations, NHIs often operate outside the scope of traditional Identity and Access Management (IAM) systems. This growing dependence on non-human users creates new attack surfaces that organizations must urgently prepare for. Without full visibility and proper oversight, NHIs may have over-permissioned standing access and static credentials, making them valuable targets for cybercriminals. To secure NHIs with the same precision as human identities, organizations must develop mo...

Threat actors engaging in phishing attacks are exploiting routing scenarios and misconfigured spoof protections to impersonate organizations' domains and distribute emails that appear as if they have been sent internally. "Threat actors have leveraged this vector to deliver a wide variety of phishing messages related to various phishing-as-a-service (PhaaS) platforms such as Tycoon 2FA ," the Microsoft Threat Intelligence team said in a Tuesday report. "These include messages with lures themed around voicemails, shared documents, communications from human resources (HR) departments, password resets or expirations, and others, leading to credential phishing." While the attack vector is not necessarily new , the tech giant said it has witnessed a surge in the use of the tactic since May 2025 as part of opportunistic campaigns targeting a wide variety of organizations across multiple industries and verticals. This includes a campaign that has employed spoofed e...

The Invisible Half of the Identity Universe Identity used to live in one place - an LDAP directory, an HR system, a single IAM portal. Not anymore. Today, identity is fragmented across SaaS, on-prem, IaaS, PaaS, home-grown, and shadow applications. Each of these environments carries its own accounts, permissions, and authentication flows. Traditional IAM and IGA tools govern only the nearly managed half of this universe - the users and apps that have been fully onboarded, integrated, and mapped. Everything else remains invisible: the unverified, non-human, unprotected mass of identities we call identity dark matter. Every new or modernized app demands onboarding - connectors, schema mapping, entitlement catalogs, and role modeling - work that consumes time, money, and expertise. Many applications never make it that far. The result is fragmentation: unmanaged identities and permissions operating outside corporate governance. And beyond the human layer lies an even larger challenge...

Popular artificial intelligence (AI)-powered Microsoft Visual Studio Code (VS Code) forks such as Cursor, Windsurf, Google Antigravity, and Trae have been found to recommend extensions that are non-existent in the Open VSX registry, potentially opening the door to supply chain risks when bad actors publish malicious packages under those names. The problem, according to Koi , is that these integrated development environments (IDEs) inherit the list of officially recommended extensions from Microsoft's extensions marketplace. These extensions don't exist in Open VSX. The VS Code extension recommendations can take two different forms: file-based, which are displayed as toast notifications when users open a file in specific formats, or software-based, which are suggested when certain programs are already installed on the host. "The problem: these recommended extensions didn't exist on Open VSX," Koi security researcher Oren Yomtov said. "The namespaces were u...

The year opened without a reset. The same pressure carried over, and in some places it tightened. Systems people assume are boring or stable are showing up in the wrong places. Attacks moved quietly, reused familiar paths, and kept working longer than anyone wants to admit. This week's stories share one pattern. Nothing flashy. No single moment. Just steady abuse of trust — updates, extensions, logins, messages — the things people click without thinking. That's where damage starts now. This recap pulls those signals together. Not to overwhelm, but to show where attention slipped and why it matters early in the year. ⚡ Threat of the Week RondoDox Botnet Exploits React2Shell Flaw — A persistent nine-month-long campaign has targeted Internet of Things (IoT) devices and web applications to enroll them into a botnet known as RondoDox.
