Cybersecurity researchers have disclosed details of an active, multi-wave campaign that employs social engineering lures themed around Adobe and Zoom software updates, business document reviews, and system maintenance utilities to stealthily deploy Remote Monitoring and Management (RMM) programs like ConnectWise ScreenConnect. The campaign has been codenamed SMOKE#SCREEN by Securonix Threat Research. "The campaign relies on a toolkit of VBScript droppers, batch file loaders, compiled .NET executables and an HTML phishing page, all ultimately pointing to a live WsgiDAV-based staging server at 207.174.0[.]143:8080," researchers Shikha Sangwan, Akshay Gaikwad, and Aaron Beardslee said in a report shared with The Hacker News. Successful attacks culminate with a ScreenConnect agent installed and beaconing to one of three attacker-controlled relay servers, providing the attackers with persistent remote access to compromised systems. The activity has not been attributed to ...

The cybersecurity industry has spent decades assuming that offensive capability scales with technical expertise. That assumption is starting to break. Security teams have long estimated risk by ranking attacker sophistication. Nation-state actors sat at one end. Organized criminal groups followed. Inexperienced attackers, dismissed as "script kiddies," sat at the other end, running public tools they didn't fully understand. Generative AI is collapsing that ranking. The next generation of attackers won't necessarily bring years of exploit development or reverse engineering experience. Instead, they'll use AI to close knowledge gaps by accelerating research, explaining unfamiliar concepts, generating code, troubleshooting errors, and adapting known techniques to new environments. The barrier to entry is dropping fast. The Economics of Cyberattacks Are Changing Every major technology shift changes economics as it changes the solutions we rely on. Clo...

Google deleted three AI agent workflows from its Agent Development Kit (ADK) Python repository. Pillar Security showed that a public GitHub issue could manipulate a triage agent into triggering a privileged code-fixing agent. The researchers said the public agent could be prompt-injected into posting /adk-issue-fix as adk-bot . They identified the bot as a collaborator, so that comment satisfied the privileged workflow's owner, member, or collaborator gate. The trusted bot identity became the authorization bridge. The team demonstrated arbitrary code execution on the continuous integration (CI) runner and exfiltration of the bot personal access token (PAT). The privileged job also held a Google API key and a Google Cloud service-account credential. Its researcher-controlled proof-of-concept attacks do not identify in-the-wild exploitation or a compromised ADK release. The exposed component was the repository automation, not a flaw in the distributed ADK Python package. Fo...

The U.S. Cybersecurity and Infrastructure Security Agency (CISA) on Monday added a high-severity security flaw impacting N-able N-central to its Known Exploited Vulnerabilities ( KEV ) catalog following reports of active exploitation in the wild. The vulnerability, tracked as CVE-2026-18577 (CVSS score: 8.2), is a case of incomplete patching for CVE-2026-18556 (CVSS score: 8.2) that allows authentication bypass and account takeover in susceptible versions of the software. The issue has been addressed in version 2026.3 HF1. "N-able N-central contains an authentication bypass using an alternate path or channel [that] allows for authentication bypass and account takeover in N-central," CISA said. Successful exploitation of the vulnerability can permit remote attackers to gain administrative access to vulnerable N-central servers and then abuse the built-in Take Control feature to pivot into managed endpoints and deploy persistence mechanisms. N-able has shared the fol...

This week kept coming back to permission. A model crossed a boundary. A wallet trusted bad randomness. Webmail kept an intruder around. Public systems, package feeds, hotel networks, and login flows all gave away more than intended. Some of it was clever. Most of it was just access left lying around: old bugs, exposed gear, poisoned dependencies, weak defaults, and tooling that moved from forum chatter to real targets. The full weekly recap report follows. ⚡ Threat of the Week Anthropic Disclosed its Models Targeted 3 Organizations - Anthropic revealed that three of its models, including Claude Opus 4.7, Mythos 5, and an unnamed research model, breached three unnamed organizations during cybersecurity testing without its knowledge. The AI firm said the earliest incidents date back to April 2026, adding it made the discoveries after launching a "large-scale retrospective review" in response to the recent Hugging Face incident. "After reviewing 141,006 evaluatio...

The Police National Legal Database (PNLD) has confirmed that police, government and customer contact information was compromised and published on the dark web. The data included names, organisations and work email addresses belonging to police officers, police staff, criminal justice professionals, government partners and customers. The incident, identified on July 26, also exposed some names and email addresses belonging to people who had submitted questions through Ask the Police. That exposure could make phishing messages targeting named officers appear more convincing, according to UK government guidance . PNLD said, "There is no evidence to suggest that passwords or other security credentials have been compromised." The service provides legal information, products and services to UK police forces and criminal justice organisations. It is not the Police National Computer or the Police National Database, is not a crime-recording system, and does not hold confidentia...

A fake browser update served over hijacked hotel Wi-Fi has been used to deliver CornFlake , a remote access trojan (RAT) that can capture webcam images, microphone audio, and keystrokes, Microsoft said in its latest report. Researchers track the operation as CaptiveCrunch and attribute it to Storm-2945 . It assesses Storm-2945 to be an operational sub-cluster of Midnight Blizzard , also known as APT29 and Cozy Bear. The U.S. and U.K. governments attribute the broader actor to Russia's Foreign Intelligence Service (SVR). On the compromised networks ReliaQuest investigated, the captive portal gateway also served as the DNS resolver assigned to connected devices. Administrative control of that gateway let the attackers forge Domain Name System (DNS) answers and redirect the resulting traffic. They could then redirect a laptop's automatic connectivity check to a fake browser or operating system update. Some pages use ClickFix instructions that tell victims to open a termina...

An academic study has disclosed a "widespread class" of security vulnerabilities impacting 4G and 5G core networks that, if successfully exploited, could trigger denial-of-service (DoS) attacks and even session hijacking, allowing an attacker to seize control of a user's network session. The findings have been released by a group of researchers from Singapore's Nanyang Technological University in a paper titled "Understanding Implicit Trust Errors in Core Carrier Networks through Multi-Agent Flaw Discovery and Analysis." The study has uncovered dozens of vulnerabilities in the signaling interfaces of LTE/5G core networks, and specifically covers two LTE implementations (Open5GS and OpenAirInterface) and five 5G implementations (Open5GS, free5GC, OpenAirInterface, SD-Core, and eUPF) across two core signaling protocols, GPRS Tunnelling Protocol Control Plane ( GTP-C ) and Packet Forwarding Control Protocol ( PFCP ). "Our research finds these vulne...

Device code phishing - the abuse of the OAuth 2.0 device authorization grant to steal access tokens - has evolved from a niche red-team technique to an industrial-scale threat in under six months. Designed for input-constrained devices like smart TVs, printers, and so on, the device authorization login flow has been adopted by a wide range of apps and use-cases that it wasn't originally intended for - most commonly CLI logins. Researchers first described the attack vector in 2020, but it took until 2024 before nation-state actors like Storm-2372 started using it in the wild. By 2025, ShinyHunters was using device code phishing against Salesforce tenants at scale, then in February 2026, the EvilTokens kit arrived and criminal adoption skyrocketed. By April, Microsoft was reporting 10 to 15 entirely new campaigns every 24 hours . Barracuda counted 7 million attacks in four weeks . The FBI issued a standalone advisory on Kali365 , the first US federal agency PSA about a specif...

Anthropic on Thursday became the latest artificial intelligence (AI) company to reveal that three of its models, including Claude Opus 4.7, Mythos 5, and an unnamed research model, had breached three unnamed organizations during cybersecurity testing without its knowledge. The AI firm said the earliest incidents date back to April 2026, adding it made the discoveries after launching a "large-scale retrospective review" in response to a recent disclosure from OpenAI that a combination of its models escaped the sandboxed environment by exploiting a previously unreported zero-day in Artifactory to obtain internet access and break into Hugging Face's production systems with an end goal to cheat on an evaluation. "After reviewing 141,006 evaluation runs where Claude could have obtained internet access, we identified three incidents in which a model accessed the internet from within or while interacting with the evaluation environment of Irregular, one of our third-...

Threat actors with ties to North Korea have been attributed to a sophisticated macOS malvertising campaign that involves redirecting users to fake web pages displaying a full-screen non-existent update sequence to deliver malware as part of a new iteration of the long-running Contagious Interview campaign. The defining aspect of the attack is that bogus macOS software update screen stealthily copies an attack command to the clipboard and then prompts the victim to execute it via the Terminal app, a known technique referred to as ClickFix . "The experience is designed to induce panic," AllSecure said in a report shared with The Hacker News. "The computer appears frozen or rebooting, so a user who believes the OS has failed follows instructions they would otherwise find suspicious." The campaign is also noteworthy for its use of blockchain-hosted command-and-control (C2), with the malware extracting the live server address from an Ethereum smart contract. Thi...

A lot of security still comes down to trusting the wrong screen. This week, that screen might be a login page, an install guide, a recruiter call, or a familiar service behaving slightly wrong. Behind it: reused credentials, exposed systems, quiet loaders, abused trust, and exploit paths that should have been harder. Some defenses improved. The loose parts still got found first. Anyway, here's the mess. The threats change every week. Subscribe, and we’ll alert you when each new ThreatsDay Bulletin is out.

A now-patched vulnerability in Azure Cosmos DB could have let an attacker escape the service's Gremlin query sandbox and obtain full read and write access to databases across customer tenants, according to Wiz. Wiz , which codenamed the chain CosmosEscape , said the exploit chain began with a crafted query against a Gremlin database controlled by the attacker. From there, code execution on a multi-tenant gateway exposed a platform-wide signing secret and a regional account directory, allowing the researchers to locate a target and retrieve its primary account key. Microsoft blocked the vulnerable Gremlin entry point within 48 hours of the November 2025 report. Wiz said Microsoft completed the longer-term fix across all regions in July 2026 and eliminated the platform-wide key. "We appreciate Wiz's work in identifying and reporting this issue through coordinated vulnerability disclosure," a Microsoft spokesperson told The Hacker News. "We have fully addres...

Hidden instructions in a Word document can make Microsoft 365 Copilot rewrite figures in a report, then copy the same instructions into the finished file. Håkon Måløy disclosed the technique on July 28, 144 days after reporting it to Microsoft. In his proof of concept, the internally generated file triggered the same behavior when it was used in a second Copilot drafting session. Måløy's timeline says Microsoft confirmed the reported behavior on March 31 and deployed two mitigations. The first blocked the original prompt wording; the second upgraded the underlying model to GPT-5.5. He said the full chain worked with modified instructions on GPT-5.6 the next day, and the attack class still reproduced on July 28. "The vulnerability class therefore remains exploitable at the time of publication," Måløy said. The attack is not zero-click and does not execute conventional malware. It requires a Copilot drafting or editing operation, and the malicious document must en...

Network firewalls are the workhorses of modern cybersecurity. They are trusted to protect the network, blocking malicious traffic and preventing intrusions and breaches. And for decades, network security teams have built controls around a relatively stable model: users connect to applications, applications exchange data, and security tools inspect packets, protocols, and destinations. Firewalls became exceptionally good at understanding where traffic was going and whether it should be allowed. But just as AI is reshaping every aspect of the business world, it's also had a monumental impact on how security teams view network traffic and the firewall. AI is driving new network dynamics that traditional security policies were never designed to govern. Employees, applications, and agents send prompts, call models, connect to services, and trigger actions across the environment, all activity most firewalls can't see, let alone understand. AI agents interact with external servic...

Broadcom has released security updates to address multiple security flaws impacting VMware ESX, vCenter, Workstation, and Fusion, three of which have been designated as critical in severity. The first of the three critical-rated flaws is CVE-2026-59309 (CVSS score: 9.8), which has been described as an authentication bypass in VMware vCenter. "A malicious actor with network access to vCenter may exploit this issue to bypass authentication and gain unauthorized access to the system," Broadcom said. The second critical flaw is a directory-traversal vulnerability in vCenter ( CVE-2026-59310 , CVSS score: 9.8) that a malicious actor with network access can exploit to execute arbitrary code. Both vulnerabilities have been addressed in the versions below - VMware Cloud Foundation, VMware vSphere Foundation versions 9.1.x.x (Fixed in 9.1.0.0300) VMware Cloud Foundation, VMware vSphere Foundation versions 9.0.x.x (Fixed in 9.0.2.0100) VMware vCenter version...

AI is compressing exploit timelines. The real question isn't whether your vulnerability management playbook needs to change, it's which part of it you've been getting wrong all along. The conversation happening in security circles right now goes something like this: Mythos is here. Exploit timelines are collapsing. Does the vulnerability management playbook need to change? The honest answer is yes. But not the part most people are focused on. The discussion around Mythos, Anthropic's frontier model and its implications for offensive security, tends to center on discovery. AI accelerates reconnaissance. It helps attackers identify exposures faster, chain techniques more efficiently, and move at machine speed through environments that were previously protected, in part, by the attacker's own time constraints. That's real. And it matters. But here's the part getting less attention: most security teams weren't winning the prioritization battle bef...

Most organizations have incident response plans, security tools, and technical teams in place. Yet new research suggests that many still lack the coordination, visibility, and executive alignment needed to withstand a serious cyberattack. According to The State of Incident Response Readiness 2026 , based on a survey of 600 senior IT security decision makers conducted by Vanson Bourne in January and February 2026, 73% of organizations admit they would not be "fully ready" if a significant cybersecurity attack occurred tomorrow. The findings point to a critical gap between having incident response capabilities and being able to execute them effectively under pressure. The report also found that cyberattacks are already a recurring business risk. More than three-quarters of organizations, 76%, experienced at least one cyberattack in the past 12 months, while 32% experienced more than one. Incident Response Readiness Remains a Weak Point Incident response has evolved f...

OpenAI on Tuesday revealed the rogue artificial intelligence (AI) agent that escaped its sealed evaluation environment and broke into Hugging Face's production environment also hacked multiple third-party accounts and services as part of the attack. The latest disclosure shows that the security incident, which stemmed from an internal security test, was more extensive in scope than previously thought. The AI company said its ongoing review of the incident revealed a "small number of cases" where the models, including GPT-5.6 Sol and an "even more capable pre-release model," identified and used exposed credentials at the account-level on other publicly-available services. "This includes four accounts on four services as part of the Hugging Face incident (and a few accounts accessed as part of other evaluations)," it said. "One of these four accounts was used as an outbound relay and staging path, and another account was used for data st...

Cybersecurity researchers have sounded an alert after finding more than 36,000 Baseboard Management Controller (BMC) management interfaces exposing Intelligent Platform Management Interface (IPMI) protocol to the public internet. Of the 36,872 internet-exposed server-management interfaces running IPMI, 24,650 have been found to disclose password-derived authentication hashes before login due to a vulnerability with the IPMI v2.0 specification itself, according to a new report Lava shared with The Hacker News. IPMI v2.0 was introduced in February 2024. The issue in question is CVE-2013-4786 (CVSS score: 7.5), a high-severity information disclosure flaw that enables remote attackers to obtain password hashes for valid accounts and conduct offline password guessing attacks by obtaining the HMAC from an RMCP+ Authenticated Key-Exchange Protocol (RAKP) message response from a BMC. Per an advisory released by Dell, "this is an inherent problem with the specification for IPMI ...
