Cybersecurity researchers have warned of a supply chain compromise impacting WordPress plugin vendor BdThemes, prompting the content management systems (CMS) platform's plugins team to temporarily disable their downloads. "Unlike traditional software supply chain attacks, zero source code files were modified within the official WordPress.org repository," Wordfence researcher Paolo Tresso said . "Instead, threat actors poisoned a static remote JSON data stream fetched by an administrative promotional banner component." The list of affected plugins is below - Element Pack Addons for Elementor – Elementor Widgets, Elementor Templates, Elementor Addons [bdthemes-element-pack-lite] - 100,000+ active installs Live Copy Paste for Elementor – Cross Domain Copy Paste & Page Duplicator [live-copy-paste] - 6,000+ active installs Pixel Gallery Addons for Elementor – Easy Grid, Creative Gallery, Drag and Drop Grid, Custom Grid Layout, Portfolio Gallery [p...

A lot of security problems still begin with someone doing a completely normal thing. Cloning a repo. Answering a call. Leaving a box exposed. Trusting the default. That pretty much covers the mood this week. Old bugs are back, supply chains are getting stranger, and some exploit paths are so short you wonder what was supposed to stop them in the first place. That’s only part of it. Here’s everything else that made the Monday recap. ⚡ Threat of the Week Anthropic's Model Attempts to Poison Open-Source Project — A new evaluation conducted by the U.K. AI Security Institute (AISI) found that AI models with access to the internet reached out into the real world to target individuals and organizations autonomously across 10 of the total of 122 runs. Of 19 such actions recorded, 17 originated from Anthropic's Mythos 5 and the remaining two involved OpenAI's GPT-5.6-Sol with cyber classifiers. In the most serious case, Anthropic's Claude Mythos 5 spent 34 hours trying...

Three separate research efforts last week demonstrated ways to defeat passkey protections without breaking the cryptography they rest on. Passkeys are designed to replace reusable passwords and resist phishing. The attacks instead reused signed authentication material that Windows had exposed, abused a cloud-synced passkey system from malware already on the victim's machine, and used a  Windows Hello for Business  key from a compromised user session without a fresh PIN or biometric check. None cracked the math. The impact is not the same in all three cases. SpecterOps showed a Windows and Microsoft Entra ID chain that could impersonate privileged users while satisfying phishing-resistant multifactor authentication (MFA); that chain reused signed authentication material rather than stealing the authenticator's private key. Unit 42 showed attacks against  Google Password Manager in Chrome , including a path that recovers the private keys for a victim's synced p...

Cybersecurity researchers have flagged a malicious Microsoft Visual Studio Code (VS Code) extension named Solidity Pro ("solidity-pro") that has been observed delivering a browser wallet and credential stealer. The names of the extensions are below - helper-beeps.solidity-pro web3devtoolsx.solidity-pro Although neither of the extensions is now available on Open VSX, the GitHub repository for " web3devtoolsx/solidity-pro " continues to remain accessible as of writing. According to Yeeth Security , early iterations of the extensions – from 1.0.0 through v2.4.x – were found to beacon to Cloudflare Workers endpoints to retrieve an encrypted Python payload and execute it. Subsequent versions starting with v3.0.0, on the other hand, have shifted to a full-blown information stealer that can collect browser profiles, crypto wallets, source-control tokens, API keys, SSH keys, and Telegram bot tokens. The captured data is then exfiltrated via a Telegram bot u...

Attacker-controlled instructions can make Atlassian's Rovo assistant collect Jira or Confluence data that a signed-in user can access, then send it to an outside server. Two security firms found that behavior independently, by different routes. Only one of those routes is confirmed closed. PromptArmor , an AI security firm, hid the instructions in content Rovo reads. It said an uploaded file was enough to make the assistant gather internal data and send it out through a URL request, with no separate approval step. The firm published on August 5, 2026 and said the chain still worked with Rovo's web-search option switched off. That bypass is single-sourced, and the report establishes the finding's status only on that date; a later remediation is not confirmed here. Varonis Threat Labs put the instructions in a link instead. It found that the rovoChatPrompt URL parameter would preload attacker instructions into Rovo Chat, so one click from an authenticated user was enou...

Metabase has warned that a maximum-severity security flaw impacting its business intelligence and data visualization software package has been exploited in the wild as a zero-day. The vulnerability (CVSS score: 10.0), which does not carry a CVE identifier, allows an unauthenticated remote attacker to inject arbitrary SQL into the Metabase application database, enabling them to gain administrator access to the instance. Armed with the elevated access, the attacker can change the application configuration, steal stored credentials for the connected databases, read any data accessible through those connections, and export data. "We recently identified that Metabase Cloud was attacked by someone utilizing an unknown ('0-day') security vulnerability in versions 1.58 and above," Metabase said in an advisory. Metabase Cloud instances have already been updated to the latest version. Users running self-hosted versions are advised to apply security patches released b...

N-able has released a fresh round of hotfixes for N‑central as part of its investigation into ongoing exploitation of a recently disclosed security flaw in the Remote Monitoring and Management (RMM) product. "We are proactively expanding protections in response to ongoing monitoring of threat actors as they evolve their attack techniques," the company said. "This is not a duplicate of our previous communication. Hotfix 2 is required, even if you already applied the earlier hotfix. Hotfix 2 supersedes Hotfix 1 with additional hardening measures to further protect you and your customers." The disclosure comes as N-able acknowledged that it detected unusual activity within a customer's environment on July 31, 2026, leading to the discovery of unknown threat actors exploiting a then-zero-day flaw in the N‑central server (CVE-2026-18577, CVSS score: 8.2). It impacts all versions prior to 2026.3.1.7. It's worth noting that CVE-2026-18577 relates to an i...

A recent wave of cyber attacks targeting financial services, private equity, and professional services has been attributed to a data extortion group known as UNC6671 . "UNC6671 continues to rely on voice phishing (vishing) to target enterprise employees, posing as IT help desk staff facilitating mandatory, urgent security migrations. Significantly, the threat actor often contacts employees via their personal mobile devices," Google Threat Intelligence Group (GTIG) and Mandiant said in a report. These calls are designed to trick victims into spoofed login portals where adversary-in-the-middle (AitM) infrastructure intercepts credentials and multi-factor authentication (MFA) tokens. The threat actors then leverage the captured data to establish session persistence and deploy automated Python and PowerShell scripts for data exfiltration from enterprise cloud environments and SaaS applications, including Microsoft 365 and Okta. According to the tech giant, UNC6671 has d...

Security researcher Malcolm Stagg has disclosed a new attack class called  NatJack  that manipulates network address translation (NAT) connection state to hijack active TCP sessions, spoof DNS responses, expose mapped ports, and exhaust NAT tables. Presented at Black Hat USA 2026 , the research found affected behavior across independently developed implementations, including Windows and Linux. Two implementation-specific flaws have been assigned CVEs:  CVE-2026-56181  (CVSS score: 8.3) in Windows NAT used by Hyper-V, and  CVE-2026-63913  (CVSS score: 8.2) in Linux Netfilter conntrack. NatJack generally requires the attacker to have privileged access to a system behind the same NAT as the victim. The mitigation guidance therefore emphasizes separating untrusted workloads from trusted systems that share NAT infrastructure. There is no single patch for the broader attack class. Organizations should apply available Windows and Linux updates and encryp...

Cybersecurity researchers have called attention to an active "widespread email-driven phishing campaign" that employs adversary-in-the-middle (AitM) techniques to take control of Microsoft 365 accounts with an aim to identify key personnel involved in financial workflows and gather related email. "The campaign uses residential proxies to disguise malicious sign-ins as ordinary consumer traffic," Arctic Wolf Labs said . "Automated activity maintains compromised sessions at approximately eight-hour intervals." The activity is assessed to impact organizations across healthcare, education, manufacturing, government, and professional services sectors located in the U.S., Canada, and Europe. It shares tactical overlaps with Payroll Pirate attacks tracked by Microsoft under the moniker Storm-2755 . Payroll Pirates is the designation assigned to a broader financially motivated threat cluster that involves hijacking the accounts of employees to reroute sal...

Entra ID researcher Dirk-jan Mollema demonstrated that malware already running in a signed-in Windows session can silently use the victim's Windows Hello for Business key to authenticate to Microsoft Entra ID. The attacker can then establish longer-term cloud access, register a device it controls, obtain a Primary Refresh Token (PRT), and add further authentication methods where tenant policies permit. On TPM-backed systems, the attacker does not extract the private key, recover the PIN, or trigger a biometric prompt. Windows ticketing keeps private-key operations available while the user is interactively signed in, allowing code running as the user to ask Windows to sign authentication data. Administrator privileges are not required. The technique requires code execution in the victim's signed-in session. Mollema describes the behavior as a consequence of how Windows Hello for Business works and says it was left as-is. The disclosure does not report active exploitatio...

A GitHub issue opened by an account with no repository privileges was enough to execute code on the CI runners behind Anthropic's and Google's own coding-agent repositories. On OpenAI's, it was enough to hijack the next agent run. Novee Security ran the attack against each vendor's agent in the configuration that the vendor ships by default, and presented the work at Black Hat USA on August 5. Two CVEs came out of it. Both are patched. Gemini CLI carries the worst of the two. CVE-2026-12537 (CVSS 4 score: 10.0) is an OS command injection in the container launcher, reached through a crafted .gemini/.env file, which lets an unprivileged attacker run code on the host of a headless CI platform before the sandbox starts. It is fixed in Gemini CLI 0.39.1 and run-gemini-cli 0.1.22. In Claude Code, CVE-2026-54316 turned Hugging Face's public download counter into an exfiltration channel that leaked an API key one character at a time, and is fixed in 2.1.163. Every ...

A new analysis has uncovered that the threat actor tracked as TeamPCP has been active on the cybercrime scene as far back as 2020, indicating the group has been compromising internet-facing infrastructure for years before training their sights on the software supply chain. "The connection is supported by overlapping domains, malware deployment paths, staging techniques, backend infrastructure, and operational tradecraft," Oligo Security researchers Avi Lumelsky and Gal Elbaz said . This includes two campaigns observed in the second half of 2025: ShadowRay 2.0 (aka IronErn), which involved hijacking artificial intelligence (AI) infrastructure into a self-propagating botnet, and TA-NATALSTATUS , which targeted exposed Redis servers to deliver cryptocurrency miners. TA-NATALSTATUS is assessed to be an evolution of a prior campaign that was detailed by Trend Micro in April 2020 that involved targeting Redis servers to deploy malware. This suggests that the threat actor h...

Zapscape , a new Linux kernel vulnerability, could allow an attacker with kernel privileges inside an L1 guest virtual machine (VM) to escape KVM isolation and execute code on the host. The risk applies when nested virtualization is exposed to untrusted guests. The flaw is tracked as  CVE-2026-64561  and affects KVM/x86's shadow memory management unit (MMU), which manages shadow page tables used for nested guest memory translation. Security researcher Hyunwoo Kim, who disclosed the bug, said the demonstrated exploit path can run commands on the host with kernel, or root, privileges. The upstream fix has been merged, and administrators running KVM hosts that expose nested virtualization to untrusted guests should update to a fixed stable kernel or a vendor package that backports the patch. The required L1 kernel privilege usually means guest root. Intel systems also require both EPT page-walk length 4 and 5 to be exposed to the L1 guest. AMD has no equivalent conditio...

Apparently, opening the thing is now enough. A repo can run before the first prompt, a package can hide among hundreds, and a harmless-looking PDF can finish the job. This week runs on cheap leverage: exposed servers, recycled bugs, poisoned agent instructions, remote-access tools dressed as support software, and trusted defaults doing attackers a favor. Nothing here is especially mystical. Just ordinary systems trusting slightly too much, slightly too early. The full list follows. The threats change every week. Subscribe, and we’ll alert you when each new ThreatsDay Bulletin is out.

Security flaws in agent infrastructure from Amazon Web Services (AWS), Google, and Vercel let untrusted or forged instructions reach an agent's tools with no check that a model turn had authorized them. In several of the attack paths, the model never ran at all, so system prompts, content filters, and model-level guardrails never got a chance to intervene. The affected products include Amazon Bedrock AgentCore's InvokeHarness API, Google's Agent Development Kit (ADK) for Python, and the Vercel AI SDK harness packages for the Codex and OpenCode coding agents. AWS has fixed the managed service, Google addressed the issues in ADK 2.5.0, and Vercel patched @ai-sdk/harness-codex in version 1.0.29 and @ai-sdk/harness-opencode in version 1.0.28. These are not identical vulnerabilities and do not share the same attack conditions. AWS involved an authenticated remote request, Google's paths required attacker-controlled session events or user-authored function calls, and V...

Connor Riley Moucka pleaded guilty in Seattle federal court on Wednesday to computer fraud, wire fraud, aggravated identity theft and a related conspiracy over the 2024 breaches of Snowflake customer accounts . The intrusions reached at least 165 organizations and exposed records belonging to at least 100 million people. Moucka, 26, of Kitchener, Ontario, personally took at least $495,000 from ransoms and data sales. He is due to be sentenced on October 27 and faces a two-year mandatory minimum on the identity theft count and up to 30 years on the rest. What got the attackers in was old passwords. The credentials had been harvested years earlier by infostealer malware and never rotated, and the accounts had multi-factor authentication (MFA) switched off. No exploit, no flaw in the platform. The Justice Department has never named the company, in Wednesday's announcement or in the October 2024 indictment, identifying the victim only as a U.S. software-as-a-service (SaaS) pr...

Cybersecurity researchers have discovered more than half-a-dozen services advertisements for illegal access to artificial intelligence (AI) models on underground cybercrime forums and messaging platforms. One such service, Poison Claude, claims to offer access to Anthropic's large language models (LLMs), including Opus 4.8, Opus 4.7, Opus 4.6, and Sonnet 4.6. "Advertisements for Poison Claude explain how the service can offer the cheap tokens: by taking advantage of free bonus credits, such as the US$100 bonus credit on AWS for Bedrock accounts," Okta researchers Jeremy Kirk and Mathew Woodyard said in an analysis published Tuesday. "The service plainly states on its website that: 'We add those accounts to our pool, your request is routed to a specific account under the hood (you don't see this), and you get charged 5-15% of the official per-token price depending on the model.'" Poison Claude accepts payments in cryptocurrencies. Once a cus...

HashiCorp, Veeam, and the Django Software Foundation have patched 11 vulnerabilities across Terraform MCP Server, Veeam Service Provider Console, and Django. The three most serious: An unauthenticated flaw in Veeam's console that hands over a managed agent's credentials, rated 9.5 A cross-tenant flaw in HashiCorp's MCP server that lets one user's Terraform token be reused for later users' requests, scored a maximum 10.0 on its CVE record A flaw in GeoDjango's spatial lookups that can write a file to disk and, on some setups, run code, reachable by a staff user with view permission on a registered model containing a spatial field Each has a fix available now. Operators should update Terraform MCP Server to version 1.1.0 or later, Veeam Service Provider Console to 9.3.0.35057, and Django to 6.0.8 or 5.2.17. Exposure is configuration-dependent: HashiCorp's bugs affect Streamable HTTP rather than stdio, Veeam's flaws affect version 9 build...

Kali365 is turning a legitimate Microsoft login into a gateway to corporate data. The phishing kit targets US organizations with attacker-controlled device codes that victims approve on Microsoft's real authentication page. Once access and refresh tokens are issued, attackers may retain access to email, documents, and cloud resources, creating a direct path to data exposure, financial fraud, operational disruption, and costly incident response. How Kali365 Targets US Organizations Kali365 is a device code phishing kit built to abuse legitimate Microsoft authentication. ANY.RUN telemetry records more than 80 public sessions linked to the campaign each week, with the United States emerging as its main geographic target. One of these sandbox sessions shows a SharePoint-themed lure used to draw the victim into the authentication flow.
