Ernst & Young, a global accounting and professional services firm, has disclosed a data breach stemming from a compromised third-party IT support platform. The incident potentially exposed sensitive information, including client documents, tax details, and employee data, which had been submitted in support tickets.
In a separate supply chain attack, Jscrambler, a JavaScript code-protection package with over 15,000 weekly downloads, was compromised after an attacker used stolen npm publishing credentials to distribute malicious releases. These packages deployed malware designed to steal developer, cloud, browser, cryptocurrency, and messaging credentials. Jscrambler has since removed the affected versions.
Coca-Cola’s US dairy subsidiary, Fairlife, confirmed a ransomware attack that temporarily disrupted production across the United States. The company stated that attackers accessed systems supporting manufacturing operations, prompting the activation of incident response and business continuity procedures. Coca-Cola has not confirmed whether data was exfiltrated during the attack.
Japan’s largest taxi operator, Nihon Kotsu, suffered a malware attack following unauthorized access to its internal network. The company responded by shutting down affected systems, which led to disruptions in taxi dispatches, telephone services, bookings, reservations, and car rentals starting July 11. Nihon Kotsu has not confirmed any theft of customer or corporate information.
Researchers have identified a China-linked campaign that leveraged AI tools, specifically Claude Code and DeepSeek, to automate various attack stages against government and financial organizations. The AI tools were used to generate scripts, adapt failed exploits, create credential-harvesting pages, and execute commands. Confirmed compromises include government systems in Thailand and Afghanistan, as well as organizations in Taiwan.
Further AI-related security concerns emerged with xAI’s Grok Build coding assistant, which researchers found could upload entire Git repositories when processing debugging requests. This included unopened files and complete commit histories, potentially exposing API keys, credentials, and and proprietary source code. Initial privacy controls did not prevent these uploads until a server-side restriction was implemented. Additionally, a weakness was verified in Anthropic’s Claude for Chrome extension, allowing malicious browser extensions to impersonate Claude and operate through authenticated user sessions. This could expose information from services like Gmail, Google Drive, or GitHub via Claude’s permissions. Anthropic has released fixes, though researchers noted a potential bypass remains.
Microsoft released 622 patches in its July Patch Tuesday, marking its largest monthly release to date. Two of these vulnerabilities were under active exploitation: CVE-2026-56164 in SharePoint Server and CVE-2026-56155 in Active Directory Federation Services, both of which could allow attackers to elevate privileges.
WordPress issued emergency updates for two critical vulnerabilities, CVE-2026-63030 and CVE-2026-60137, collectively dubbed "wp2shell." These flaws allow unauthenticated remote code execution and website takeover. Affected versions include 6.9.0 through 6.9.4 and 7.0.0 through 7.0.1, with fixes available in versions 6.9.5 and 7.0.2.
SonicWall released a hotfix for CVE-2026-15409 and CVE-2026-15410, two critical vulnerabilities impacting SMA 1000 Series gateways. These flaws enable unauthenticated attackers to execute system commands on vulnerable appliances, and active exploitation has been linked to Inc ransomware.

JetBrains is urging Cadence users to revoke and rotate all credentials following a security incident last month in which unidentified threat actors exploited a recently disclosed critical vulnerability in TeamCity to breach its own environment. "Cadence users should immediately revoke or rotate all credentials and secrets that may have been used to run their Cadence executions," JetBrains said.
A weakness has been identified in Tenda CP3 27.5.57.101. This issue affects some unknown processing of the file Net/NetCheckPing.cpp. This manipulation of the argument interface_name/host causes os command injection. The attack can be initiated remotely.
A security flaw has been discovered in Tenda CP3 27.5.57.101. This vulnerability affects the function SystemAsh of the file Apis/system.c of the component Kylin. The manipulation of the argument AlarmVoiceURL results in os command injection. It is possible to launch the attack remotely.

OpenAI has announced a $1 billion commitment to provide subsidized access to its Daybreak AI cybersecurity tools for under-resourced critical infrastructure defenders. The initiative, named Daybreak for Frontline Defenders, will offer AI models, training, and technical support over the next six months, prioritizing water and wastewater utilities, electric grid operators, and local government entities. This move aims to equip organizations with limited budgets and staff against increasingly sophisticated cyber threats.

Attackers are exploiting a new unpatched vulnerability in Magento Open Source and Adobe Commerce that lets them run malicious code on an online store's server without logging in, Dutch e-commerce security company Sansec said in an advisory published on September 5. Sansec, which discovered the flaw and named it StyleSmuggler, said attacks started on September 4. "Sansec is publishing early
In BPF instructions that load/store a value from/to a scratch memory register the register index is an unsigned 32-bit integer and must not exceed 15, but libpcap BPF interpreter does not validate the value. In particular uncommon use cases a crafted filter program can cause the interpreter to try reading and writing the OS process memory in the 16GiB starting at the current stack frame on 64-bit architectures and in the entire address space on 32-bit architectures.
