A Chinese threat actor tracked as UAT-7810 is actively refining its bespoke malware to expand its Operational Relay Box (ORB) network by breaking into internet-facing networking devices. According to findings from Cisco Talos, UAT-7810 is an advanced persistent threat (APT) actor that's responsible for maintaining and proliferating LapDogs , an ORB network that first came to light in June 2025. "UAT-7810 is most likely tasked with establishing Operational Relay Box (ORB) networks that can then be leveraged by associated secondary threat actors to conduct their own malicious attacks against high value targets," researchers Jungsoo An, Asheer Malhotra, Vanja Svajcer, and Brandon White said . One such China-nexus threat actor that has leveraged the infrastructure in its own attacks is UAT-5918 , which has been linked to cyber attacks targeting critical infrastructure entities in Taiwan since at least 2023 with an aim to establish persistent access within victim envir...

Researchers at  Nebula Security  have disclosed GhostLock ( CVE-2026-43499 ), a 15-year-old Linux kernel flaw that lets any logged-in user take full root control of a machine that has not been patched. The vulnerable code has shipped by default in essentially every mainstream distribution since 2011. The flaw needs no special permission, no unusual settings, and no network access; ordinary threading calls from any local program are enough. Nebula turned it into a working root exploit that is 97% reliable in its testing and also escapes containers, and says Google awarded the team $92,337 through its  kernelCTF  bug-bounty program. No one is known to be exploiting it in the wild, but Nebula has published  working exploit code , so anyone can now run it. Patching is the priority. How the bug works The kernel has a system for keeping an urgent task from getting stuck behind a trivial one. Part of it is a cleanup step that tidies up after a task...

The U.S. Cybersecurity and Infrastructure Security Agency (CISA) on Tuesday added four security flaws to its Known Exploited Vulnerabilities ( KEV ) catalog, citing evidence of active exploitation. The vulnerabilities are listed below - CVE-2026-48282 (CVSS score: 10.0) - A path traversal vulnerability in Adobe ColdFusion that could lead to arbitrary code execution in the context of the current user. CVE-2026-56290 (CVSS score: 10.0) - An improper access control vulnerability in Joomlack Page Builder that could allow for remote code execution via unauthenticated arbitrary file upload. CVE-2026-55255 (CVSS score: 6.1) - An authorization bypass through a user-controlled key vulnerability in Langflow that could allow an authenticated attacker to execute any flow belonging to another user by specifying the victim's flow ID in the request. CVE-2026-48908 (CVSS score: 10.0) - An unrestricted upload of a file with a dangerous type vulnerability in JoomShaper SP P...

A new Android malware operation called RedWing is being rented out on Telegram as a ready-made bank-fraud service. It lets even low-skill criminals take over a victim's phone, steal their banking logins, and capture the one-time codes that protect their accounts. Zimperium's zLabs , which found the operation, says it looks like a new variant of Oblivion , a $300-a-month rent-a-malware tool documented earlier this year. RedWing is sold as a complete product, in subscription tiers with referral discounts, guides, and how-to videos, so a buyer needs no malware-writing skill. A Telegram bot builds each buyer a custom app on demand. Researchers say a substantial number of the resulting droppers and payloads currently evade conventional security tools. Infection starts with a phishing link that opens a fake app-store page. The kit's dropper builder can mimic Google Play, the Galaxy Store, and AppGallery, or build fully custom pages, complete with fake ratings, reviews, ...

A critical flaw in Google's Dialogflow CX could have let an attacker with edit rights on one Code Block-enabled agent compromise other Code Block-enabled agents in the same Google Cloud project. From there, they could read live conversations, steal the data users shared, and make the bots send attacker-written messages, including requests to re-enter a password. Security firm Varonis found it and named it Rogue Agent. The flaw affected only organizations that built agents with Dialogflow's Playbooks and custom Code Blocks, which let developers add their own Python. And it was not a remote, unauthenticated attack. Pulling it off needed the dialogflow.playbooks.update permission on one such agent, which limits the realistic attacker to a malicious insider or a compromised developer account, not a stranger on the internet. From that one foothold, though, the reach extended to every agent in the project. Google has fixed it, and both Varonis and Google say there is no sig...

A Microsoft 365 device code phishing campaign has been observed leveraging collaboration-themed lures to take control of victim accounts between the last week of June 2026 and into early July, per findings from ZeroBEC. "The campaign did not depend on a fake Microsoft password page. It used a malicious collaboration-style lure to push users into the legitimate Microsoft device login experience, while a backend broker generated and polled Microsoft Authentication Broker device-code tokens," the email security company said in a report shared with The Hacker News. The activity is assessed to share "strong" overlaps with a campaign documented by Microsoft in February 2025 under the moniker Storm-2372 , including the use of messaging or Teams-style lures to trick unsuspecting victims into entering an attacker-provided device code, along with their credentials, effectively allowing the threat actor to recover the token and hijack their account. Despite these simi...

A public issue can trick GitHub Agentic Workflows into leaking the contents of an organization's private repositories, researchers at Noma Security have shown. The attacker needs only to open a normal-looking issue on a public repository, with no stolen credentials and no access to the organization. If that organization has given the agent read access across its repositories, private ones included, the issue can steer it into pulling private contents into a public comment. Noma calls the technique GitLost . The target is GitHub Agentic Workflows , a feature now in public preview that GitHub launched in February. Instead of writing automation scripts, you write instructions to an AI agent in plain English in a Markdown file. The agent reads issues and pull requests, runs tools, and replies on its own. It can be powered by GitHub Copilot, Anthropic's Claude, Google Gemini, or OpenAI Codex. Workflows are read-only by default, but an organization can hand one a token with...

U.S. prosecutors linked an alleged Scattered Spider hacker to a break-in at a luxury jewelry retailer using a persistent Windows device ID, according to a newly unsealed federal complaint . Microsoft records tied that ID first to the account the attackers used to keep access during the May 2025 intrusion, then to online accounts prosecutors say belong to 19-year-old Peter Stokes. Stokes is charged with conspiracy, computer intrusion, and fraud. A dual U.S.-Estonian citizen known online as "Bouquet," he was extradited from Finland and made his first court appearance in Chicago on June 30, as THN reported . He is presumed innocent pending trial. How the break-in worked Between May 12 and 15, 2025, attackers phoned the retailer's IT help desk from Google Voice numbers, posed as locked-out employees, and got staff to reset employees' passwords and the mobile devices tied to their multifactor authentication. Within a few hours, they controlled three accounts, t...

Cybersecurity researchers have disclosed details of a now-patched critical session isolation vulnerability in Writer , an enterprise generative artificial intelligence (AI) platform, that could result in cross-tenant compromise. The one-click vulnerability has been codenamed WriteOut by the Sand Security Research team. "An outsider could go from having no access to taking over any Writer AI organization inside industry-leading enterprises, with nothing more than a link," the cybersecurity company said in a report shared with The Hacker News. Put differently, the shortcoming could be abused to take over a victim's Writer account, and use it to access private chats, documents, and other sensitive data related to agents, configurations, private models, connectors, and large language model (LLM) credentials. Even worse, it could be abused to seize administrative control depending on the victim's role. An important aspect of the flaw is that the attacker and the...

Software supply chain security was hard enough. Then AI joined the build pipeline. For five years, "software supply chain security" meant one question: what's in your code? Which open-source packages, which versions, which transitive dependencies three layers deep that nobody chose on purpose? SolarWinds, Log4Shell, and XZ Utils all taught the same lesson: the risk lives less in the code a team writes and more in everything that produces it. Shai-Hulud, the self-propagating malicious package campaign that spread through developer toolchains this year, taught the next one: knowing what's in your code is still necessary, but it's no longer sufficient. In the roughly 20 months since the Model Context Protocol launched, AI tools, models, and the infrastructure around them have become load-bearing parts of how software gets built, deployed, and run. Code is written by agents. Packages are pulled in by autonomous tools that decide they are needed. Prompts have...

A suspected China-aligned threat activity cluster has been observed exploiting Roundcube webmail software belonging to physics and engineering departments of U.S. and Canadian universities as part of a new campaign. The activity involves the exploitation of now-patched, critical security flaws in the open-source email solution, such as CVE-2024-42009 (CVSS score: 9.3), to siphon credentials, followed by either the deployment of a web shell for persistent access or a known post-exploitation tool called VShell . The emerging threat cluster is being tracked by Proofpoint under the moniker UNK_MassTraction . It was first detected in May 2026, specifically focusing on administrators and professors in departments with either national security ties or entities studying astrophysics and particle physics. "The emails targeting university departments used both compromised senders, as well as abused domains vulnerable to spoofing due to lax DMARC policy to send the emails," the ...

Several versions of firmware released by Chinese network device manufacturer Tenda have been found to embed an undocumented authentication backdoor that enables administrative access to the devices' web management interfaces, the CERT Coordination Center (CERT/CC) warned Monday. "An attacker can exploit this vulnerability, tracked as CVE-2026-11405 , to bypass the password verification process and obtain full administrative control without valid credentials," the CERT/CC said in an alert. The vulnerability impacts multiple versions of the firmware - US_FH1201V1.0BR_V1.2.0.14(408)_EN_TD US_W15EV1.0br_V15.11.0.5(1068_1567_841)_EN_TDE US_AC10V1.0re_V15.03.06.46_multi_TDE01 US_AC5V1.0RTL_V15.03.06.48_multi_TDE01 US_AC6V2.0RTL_V15.03.06.51_multi_T The backdoor functionality is present within the "login()" function of the "/bin/httpd" web server binary. While the method initially follows a normal authentication path using MD5-based p...
