Australia warns of a global campaign hitting websites through known CMS flaws

Australia's Cyber Security Centre has warned of a large-scale global campaign in which attackers scan websites and exploit known vulnerabilities in content management systems and their plugins to plant web shells. The affected software spans WordPress, Joomla, Craft CMS, and others, with the flaws typically allowing unauthenticated file upload, remote code execution, or server-side request forgery. Once a web shell is installed, attackers can take a site offline, deface it, steal data stored on the server, or pivot deeper into the network. Many small and medium-sized businesses have already been hit, and the agency notes the campaign may be accelerated by AI, which helps attackers scale exploitation of newly disclosed flaws.

Check
Inventory your public websites and their CMS platforms, themes, and plugins, apply outstanding security updates, remove unused components, and review access and network logs and existing accounts for signs of compromise.
Affected
Organizations running internet-facing CMS platforms like WordPress, Joomla, or Craft CMS with unpatched plugins; attackers automatically exploit known flaws to plant web shells, disproportionately hitting small and medium-sized businesses.
Fix
Patch CMS software and plugins promptly, enable automatic updates where possible, make web directories read-only where feasible, restrict access to sensitive directories, and restore from a known-clean backup if compromise is found.

Glendale College breach exposes data on 793,000 students and applicants

Glendale Community College has had data on roughly 793,000 people exposed after the extortion group ShinyHunters stole files from its student information systems. Have I Been Pwned indexed 793,925 accounts, and the attackers claim to have taken more than 62GB across roughly 304,000 files, including student records with personal identifiers, financial aid exports, immunization logs, admission checklists, and transcripts dating back to 2020. The theft came from the college's PeopleSoft Campus Solutions environment, tying it to the wider ShinyHunters campaign against Oracle PeopleSoft that has hit numerous universities and companies. The breadth of academic and personal data raises the risk of identity theft and targeted phishing against students, applicants, and staff.

Check
People connected to Glendale Community College as students, applicants, or staff should watch for a breach notice, check Have I Been Pwned, monitor financial accounts, and be alert to college-themed phishing.
Affected
Around 793,000 Glendale Community College students, applicants, and staff whose personal, academic, financial aid, and health-related records were exposed; the depth of data supports identity theft and convincing targeted phishing.
Fix
Affected people should consider a credit freeze and monitor accounts. Organizations using Oracle PeopleSoft should apply its mitigations, review access logs, and enforce phishing-resistant MFA against this ongoing campaign.

Ghostcommit hides secret-stealing instructions inside images to slip past AI reviewers

Researchers at the ASSET Research Group demonstrated Ghostcommit, an attack that hides malicious instructions inside a PNG image so AI code reviewers miss them entirely. A harmless-looking conventions file points the coding agent to the image, whose rendered text tells the agent to read the repository's .env file and encode its secrets as a list of numbers written into the code. Because tools like CodeRabbit and Bugbot skip image files by default, the pull request passes review clean; the trap springs later when a developer asks the agent for an unrelated task. The outcome depended on the tool wrapping the model: some agents leaked secrets, while Claude Code refused.

Check
Review how your AI code reviewers and coding agents handle images and convention files like AGENTS.md, and check whether reviewers inspect image contents rather than skipping them as opaque binary files.
Affected
Teams using AI code reviewers that skip images and coding agents that auto-follow repository convention files; a merged pull request can later drive an agent to read .env and leak its secrets.
Fix
Configure AI reviewers to inspect image contents, treat convention files and repo content as untrusted input, keep secrets out of agents' reach, and require human review before agents read sensitive files.

Compromised jscrambler npm releases dropped a cross-platform infostealer on install

Attackers used a stolen publishing credential to push malicious versions of the jscrambler npm package that install a Rust infostealer as soon as the package is added to a project. Socket ties five bad versions to the same actor, published over about three hours; the malware ships as native binaries for Windows, macOS, and Linux and sweeps developer machines for cloud credentials, crypto wallets, and password-manager vaults. Because jscrambler is a build-time tool used in development and CI, the stealer runs where deploy tokens, cloud keys, and source code live. Partway through, the dropper moved into the package's main code, so installing with scripts disabled does not stop it.

Check
Check lockfiles, package logs, and CI records for the malicious jscrambler versions installed since July 11, move to a clean release or pin to 8.13.0, and clear affected versions from caches.
Affected
Developers and CI pipelines that installed the malicious jscrambler versions; the infostealer captures AWS, Azure, and Google Cloud credentials, crypto wallets and seed phrases, and password-manager vaults from the build environment.
Fix
Remove the bad versions, rotate every credential exposed in affected developer and CI environments, hunt for temp-directory binaries and hidden persistence, and pin and verify dependencies rather than trusting a maintainer account.

RedHook Android malware abuses wireless debugging to seize shell-level control

Group-IB detailed a new version of the RedHook Android banking trojan that gains shell-level control of a phone by abusing the operating system's own wireless debugging feature, with no computer or root needed. Once a user is tricked into granting Accessibility permissions, the malware silently taps through Settings to enable Developer Options and Wireless Debugging, then pairs over the loopback interface to run privileged commands. From there it can silently install or remove apps, change secure settings, log keystrokes, stream the screen, and steal credentials, while an aggressive persistence stack keeps it running through reboots. It spreads through social engineering, with attackers impersonating government or bank staff.

Check
Remind users to install Android apps only from official stores, distrust calls or messages urging them to install an app or enable Accessibility, and review which apps hold Accessibility permissions.
Affected
Android users tricked into sideloading the malware and granting Accessibility; RedHook then enables wireless debugging to gain shell-level privileges, letting it control the device, steal banking credentials, and resist removal.
Fix
Keep installs restricted to official app stores with Play Protect enabled, treat Accessibility requests with suspicion, and for organizations, monitor or block wireless-debugging activation and enforce mobile threat defense on banking devices.

Lone operator exploited Langflow flaws to steal AI and cloud keys across tenants

Sysdig detailed a financially motivated operator who chained two Langflow vulnerabilities to raid the AI orchestration platform for credentials, part of why CISA just added one of them to its exploited-vulnerabilities catalog. Using a cross-tenant access flaw (CVE-2026-55255), the attacker ran flows belonging to other tenants to steal their large language model provider keys and AWS keys, while a separate unauthenticated code-execution flaw (CVE-2026-33017) took over the host itself. The activity, observed in late June against an internet-exposed Langflow instance, followed a methodical pattern of reconnaissance, flow enumeration, and credential theft. It underscores that AI orchestration platforms concentrate valuable secrets and are increasingly a direct target once left exposed online.

Check
Identify any internet-exposed Langflow instances, confirm they are patched against the recent flaws, restrict them from public access, and review logs for cross-tenant flow access and unexpected outbound connections.
Affected
Organizations running exposed or unpatched Langflow (CVE-2026-55255, CVE-2026-33017); attackers can execute other tenants' flows to steal AI and cloud keys and run code on the host, harvesting concentrated credentials.
Fix
Patch Langflow, keep it off the public internet, rotate any potentially exposed AI provider and cloud keys, apply least privilege and short-lived credentials, and monitor for cross-tenant access and credential-harvesting behavior.

Progress tells ShareFile customers to shut down file servers over credible threat

Progress Software has told ShareFile customers to immediately shut down the on-premises Windows servers running Storage Zone Controllers, citing a "credible external security threat" against its enterprise file-sharing platform. The company has temporarily disabled access to affected accounts and says it has no sign of unauthorized access yet, but it has not disclosed what the threat is or whether a vulnerability is involved. Ordering a full shutdown rather than a patch strongly suggests there is no fix available. Only self-hosted Storage Zone Controllers, which typically sit internet-facing at the network edge, are affected, not cloud-only ShareFile. Progress also makes MOVEit, whose 2023 zero-day was mass-exploited by the Clop group.

Check
Determine whether you run ShareFile Storage Zone Controllers, and if so, follow Progress's guidance to shut down the hosting Windows servers now, while preserving system and administrative logs for investigation.
Affected
Organizations running on-premises ShareFile Storage Zone Controllers, which broker files between local storage and the ShareFile cloud and are usually internet-facing; cloud-only ShareFile accounts are not affected by this advisory.
Fix
Shut down Storage Zone Controller servers as Progress directs until a fix or all-clear is issued, review recent administrative activity and internet exposure, and watch for Progress updates.

Six U-Boot bootloader flaws could run code before a device checks its firmware

Researchers at Binarly found six flaws in U-Boot, the open-source bootloader inside routers, IoT devices, industrial systems, and the management chips of data-center servers. All six are triggered while U-Boot is still reading an untrusted firmware image, before it verifies the signature, so an attacker who supplies a malicious image can act before the trust check runs. Two of the flaws can lead to arbitrary code execution at boot, undermining the whole chain of trust, while the other four crash the device. The vulnerable code dates back to 2013, affecting many releases and vendor forks. Exploiting them does not always need physical access: a compromised management interface could push a malicious image.

Check
Identify devices built on U-Boot, especially servers with baseboard management controllers and networking or IoT gear, and check with vendors whether firmware updates addressing these flaws are available or planned.
Affected
Devices using U-Boot, including many routers, IoT and industrial systems, and server management controllers; malicious firmware images can crash them or run code at boot before the signature is verified.
Fix
Apply vendor firmware updates as they incorporate the upstream fixes, restrict and monitor access to management interfaces that can push firmware images, and retire devices no longer receiving updates.

Zimbra patches critical flaw letting a crafted email run code in your session

Zimbra is urging customers to update after fixing a critical stored cross-site scripting flaw in the Classic Web Client of its widely used email and collaboration platform. A specially crafted email can run malicious scripts when it is simply opened, potentially exposing mailbox contents, session data, and account settings, and enabling session hijacking or credential theft. The flaw, reported by Google's Threat Analysis Group, has no CVE assigned yet and is not confirmed as exploited, but the group often surfaces bugs used by state-backed actors. Zimbra's web client has been a repeated target: Russian-linked groups have exploited similar cross-site scripting flaws against government and military organizations. Updating to version 10.1.19 fixes it.

Check
Identify Zimbra Collaboration servers using the Classic Web Client, confirm their versions, and prioritize updating any that are internet-facing or serve high-value users such as executives and administrators.
Affected
Organizations running Zimbra Collaboration's Classic Web Client before version 10.1.19; an attacker can run code in a victim's session by sending an email the victim opens, risking mailbox and credential theft.
Fix
Update Zimbra Collaboration to version 10.1.19 promptly, given the platform's history of state-actor exploitation, and consider moving users to the modern web client and monitoring for suspicious email-borne scripts.

Fake Go scanning tool hides malware across 222 GitHub repositories

Researchers at Socket uncovered a network of 222 GitHub repositories, tracked as Operation Muck and Load, built to spread Windows malware through a fake Go module posing as a DNS and subdomain scanner. Running the module quietly launches PowerShell that pulls an encrypted payload from attacker infrastructure and deploys infostealers, remote access trojans, and cryptominers. To look trustworthy, the operators used an automated workflow that force-pushes fake commits every minute, making repositories appear actively maintained and generating hundreds of package versions. More than 700 of the module's 1,200-plus versions were malicious. The lures cluster around crypto wallets, Telegram bots, and game cheats, aimed at people likely to run untrusted code.

Check
Review whether developers pulled Go modules or ran tools from unfamiliar GitHub repositories, particularly crypto, wallet, or game-cheat-themed ones, and watch for hidden PowerShell launching from a supposed utility on developer machines.
Affected
Developers and users who clone, build, or run code from these lure repositories; a module posing as a legitimate scanner instead installs infostealers, remote access trojans, or cryptominers on their Windows machines.
Fix
Verify a repository's authenticity beyond how active it looks, since fake commit activity can be manufactured, prefer official module sources, inspect code before running it, and use isolated environments for untrusted tools.
