Breach-tracking service Have I Been Pwned has confirmed that 305,216 accounts were exposed in the March attack on Berkadia, a large US commercial real estate finance firm that handles mortgage banking and investment sales. The extortion group ShinyHunters claimed the intrusion, saying it stole millions of Salesforce records containing personal and internal corporate data, around 27GB compressed, and threatened to leak them after the company did not meet its deadline. The breach is part of a broad ShinyHunters campaign this year against companies' Salesforce environments, typically entered by socially engineering employees or help desks rather than exploiting a software flaw.
Have I Been Pwned has confirmed 137,123 accounts exposed in a breach of Infinite Campus, a widely used K-12 student information system in the US. The extortion group ShinyHunters claimed the attack back in March, posting that it had stolen personal data and internal corporate information. Because student information systems hold sensitive records on minors and their families, exposed data raises the risk of identity theft and highly targeted phishing aimed at parents, students, and school staff. The incident fits the same ShinyHunters data-theft pattern seen across the education sector this year, including the much larger Canvas breach.
Splunk has patched a critical flaw in Splunk Enterprise that lets an unauthenticated attacker run code on the server, a serious risk given Splunk often sits at the heart of a company's security monitoring. The bug (CVE-2026-20253, rated 9.8) is in the PostgreSQL sidecar service added in Splunk 10, whose internal API has no authentication yet is reachable through the main web app's proxy. An attacker can write or overwrite files on the host and chain that into remote code execution. The sidecar is off by default on on-premises Windows but enabled out of the box on Splunk Enterprise running in AWS. Splunk Cloud is not affected.
Researchers at Tenet Security have disclosed Agentjacking, a new attack that turns AI coding assistants like Claude Code, Cursor, and Codex into tools for running an attacker's code on a developer's machine. The trick abuses Sentry, a widely used error-tracking service: anyone can submit a fake error event using a project's DSN, a public write-only key embedded in website code, and the AI agent, fetching that event through Sentry's MCP integration, cannot tell the malicious instructions from real diagnostics and runs them with the developer's privileges. No phishing, malware, or server breach is needed, and it bypasses traditional controls because every step is technically authorized. Tenet found 2,388 exposed organizations.
Attackers hijacked more than 400 packages in the Arch User Repository (AUR), the community add-on store for Arch Linux, in a supply-chain attack dubbed Atomic Arch. Rather than exploiting a flaw, they adopted abandoned packages and quietly edited the build recipe (PKGBUILD) to pull in a malicious npm package, atomic-lockfile, at install time. The payload is a Rust credential stealer that grabs browser logins, SSH keys, crypto wallets, and developer tokens; when run as root it also loads an eBPF rootkit that hides its processes, files, and network connections. Only the AUR is affected, not Arch's official repositories. The package names and histories looked completely normal.
Sygnia has detailed Operation Highland, a campaign in which the China-linked group Velvet Ant hid inside the Linux authentication stack itself for close to a decade, with traces back to 2016. Instead of dropping detectable malware, the attackers replaced the trusted PAM login module (pam_unix.so) and OpenSSH binaries with backdoored versions, found in nine distinct variants. Some accepted a hardcoded secret password; others silently logged real usernames, passwords, and every command typed, with a hidden switch to turn logging off. Because login programs are trusted and rarely inspected, the activity looked like normal administration and evaded scanners on a network with no direct internet access.
A critical flaw in phpBB, the open-source forum software running on thousands of sites, lets an unauthenticated attacker obtain a valid login session as any user, including an administrator, with a single HTTP request. The bug (CVE-2026-48611, rated 9.4) works in the default configuration and traces back to code from 2014. An admin session gives full read, write, and delete access to the forum and, on the latest branch, opens a path to remote code execution and full server takeover. A second, lower-severity flaw affecting only OAuth-configured installs was also fixed. phpBB released version 3.3.17 to patch both.
Check Point has disclosed three now-patched flaws in LangGraph, the popular LangChain framework for building AI agents, that can be chained for remote code execution on self-hosted servers. The chain combines an SQL injection (CVE-2025-67644) with an unsafe msgpack deserialization bug (CVE-2026-28277): an attacker who can reach the agent's stored-state endpoint plants a malicious checkpoint that runs code when loaded. A compromised LangGraph server exposes everything the agent can touch, including model API keys, customer data, and internal network access. It is only exploitable in self-hosted deployments using the SQLite or Redis checkpointer; LangChain's managed LangSmith platform is not affected.
The Iran-linked group Handala claims it breached California Water Service (Cal Water), one of the largest US investor-owned water utilities, and published a 5GB sample to prove it. Analysts say the attackers reached a customer billing database holding personal data (names, addresses, account and payment details) and an internal GPS-correction server, leaking administrative credentials in the process. Handala framed the attack as retaliation for US actions against Iran and boasted it could disrupt water supply, but researchers stress the evidence does not support that claim, neither system controls water treatment, and the group is known to exaggerate. Cal Water has not yet publicly confirmed the incident.
Novo Nordisk, the pharmaceutical giant behind Wegovy and Ozempic, has disclosed that attackers copied data from its internal IT systems, including information on patients in some of its clinical trials. The company stressed the patient data was de-identified, containing fields like patient ID, year of birth, sex, biomarkers, and lifestyle factors rather than names or direct identifiers. Novo has not said how many people are affected or named the attacker, and is not offering credit monitoring, instead advising patients and healthcare professionals to stay alert for unexpected messages or calls. Pharma firms are increasingly targeted for their valuable research and patient data.
