The signal, not the noise, in security. Six things from this week worth your five minutes.
FBI Investigating Alleged ShinyHunters Breach of Its Jobs Site
The FBI confirms it is investigating "claims regarding unauthorized activity affecting FBIjobs.gov," and the special-agent application portal was still offline as of Wednesday, with a ShinyHunters defacement — a Pokémon mascot in place of agency images — visible on the site. Beyond that, most of the story is the group's own claims: 2–3 TB of data from FBI Criminal Justice, HR, and Medlink systems and AWS GovCloud, taken through an Oracle PeopleSoft zero-day, covering "every" agent and applicant. No CVE has been assigned, BleepingComputer couldn't verify the zero-day, and Oracle hasn't responded. What has been independently checked is narrower: 404 Media verified that some of a 5,000-record sample, with names, phone numbers, and addresses, was accurate.
The motive is retaliation. ShinyHunters wants the FBI to correct or remove a May FLASH advisory that says the group exaggerates its access and uses swatting and family threats, claims the group denies. It set a one-week deadline and says it will release everything otherwise; one security expert expects it will, since the FBI is unlikely to comply. The same group hijacked Cl0p's leak site last week through an unauthenticated file-upload flaw in its Grav CMS and demanded an eight-figure payment from the ransomware gang itself, so it clearly doesn't shy away from high-profile targets.
The broader lesson concerns the target type: a jobs portal is an internet-facing HR application connected to systems that hold employees' personal details, and applicant-facing systems are routinely scoped as low risk while sitting close to the HR core. Segment them as if a front-end compromise were a compromise of the data behind it, and patch enterprise HR platforms like the internet-facing systems they are. Then assume the perimeter fails anyway: legacy applicant and employee data should be archived out of the portal's reach and encrypted, with PKI controlling who holds the keys, so an attacker who reaches the files still can't read them. That is data-at-rest and data-in-flight encryption working together, as argued in Encryption at Rest and in Transit.

Attackers Exploit WordPress CVE-2026-87902 Within Hours of Disclosure (CVE-2026-87902, CVSS 9.2)
A path-traversal flaw in WordPress's page-template resolution lets an unauthenticated attacker make get_page_template() include a readable local PHP file from outside the theme directory — and on some servers that becomes remote code execution. WordPress shipped fixes on September 22 (7.1.2, with backports to 7.0.6, 6.9.9, and 6.8.10). Patchstack recorded reconnaissance within hours (11:49 UTC the same day), real compromises by September 23, and traffic more than ten times the first evening's volume. The first payloads matched the exact encoding the patch addresses, which suggests attackers worked from the patch diff rather than finding the bug themselves.
Exploitation has two preconditions: the active theme's top-level directory name must begin with page-, and the web server account must be able to read a useful PHP file, commonly pearcmd.php with register_argc_argv enabled. Not every site is exploitable, but that's a poor thing to bet on. For the second issue running, the window between fix and mass exploitation was hours, not sprints, so enable automatic core updates and treat a critical fix as an emergency change, not a backlog item.
Patching closes the hole, but layers cover the gap while you do. A web application firewall can help mitigate RCEs like this one through rules that block the exploit pattern; run it in audit mode first to tune the rules against real traffic, then move it to prevention mode. Pair it with IAM so that authorization is enforced on every CRUD operation, not just at login. That is defense in depth: no single control, including the patch, has to be perfect.

Check Point Warns of Hackers Exploiting Security Gateway VPN RCE Flaw (CVE-2026-85102)
A pre-authentication remote code execution flaw in the certificate handling of Check Point's Security Gateway VPN affects R81.20, R82, and R82.10, plus Spark firewalls, both locally and remotely managed. Check Point says exploitation began September 12 with a wave of attempts against Spark customers, routed through VPNs and proxies, using certificates with subjects like CN=vpn,OU=users,O=global. The fix is LivePatch Take 26 or a Jumbo Hotfix (R81.20 Take 166, R82 Take 126, R82.10 Take 44, or R81.10 Take 190 or later). CISA added this flaw, along with the management-server zero-day CVE-2026-93616, to its Known Exploited Vulnerabilities catalog with a September 25 federal deadline.
The workaround carries the real lesson: disable the VPN implied rules and restrict site-to-site VPN traffic to explicit peer IPs. The exposure exists because the VPN listener is reachable from the whole internet, and a gateway that only talks to known peers shouldn't be. A source-IP allowlist turns a pre-auth RCE from an internet-wide problem into a partner-network one. Perimeter gateways are a recurring initial-access path, so their patch cadence should match their exposure.
Layer more conditions on top of the allowlist. Geo-IP blocking shrinks who can reach the listener at all, so the gateway stops answering from regions where you have no users or partners. Off-hours access is another useful signal: require a second factor before granting access outside normal working hours. One honest limit: step-up authentication can't stop a pre-authentication flaw like this one, because the exploit fires before any login, but it does limit what stolen credentials can do. The network-level controls are what shrink exposure to this bug.

Attackers Use Malicious Terraform Providers to Deliver Go Malware via HashiCorp Registry
Aikido researchers found four malicious packages: two Terraform providers on HashiCorp's registry, gocommunity-io/dockerd (222 downloads) and kreuzwenker/docker (1,449), and two Go modules, gocommunity.io/orderedbtree and gogets.dev/btreex. The Go malware collects system information and phones home over two channels: Slack, for data and file transfer, and an Ethereum smart contract on the Arbitrum Sepolia testnet, polled every three seconds for encrypted commands that run as Go or JavaScript code. Attribution is to North Korean operators tied to the Graphalgo campaign that ReversingLabs documented in February. Delivery is social: fake Web3 companies recruit developers on LinkedIn, Facebook, and job forums, then hand out a coding task in a benign-looking GitHub repository that pulls in the malicious dependency. The source doesn't confirm whether HashiCorp has removed the packages.
Infrastructure-as-code registries are now a supply-chain target just like npm. A Terraform provider runs with the credentials of whoever runs terraform apply, which is often a cloud admin or a CI role, so run plan and apply from CI with least-privilege roles rather than from laptops holding broad cloud credentials. And treat the unsolicited coding test as the attack it may be: open untrusted repositories in a disposable sandbox, not on a machine that holds cloud credentials.
How do developers confirm a library is what it claims to be? Start with what the tooling already provides. Terraform records provider checksums in .terraform.lock.hcl and verifies them on terraform init, and Go pins every module's hash in go.sum, backed by a public checksum database, so commit both files and review any change to them. Registry signatures show a package matches what its publisher signed, not that the publisher is trustworthy. Check who the publisher is: these came from third-party namespaces, not HashiCorp's own, and low download counts are one more signal worth noticing. Then add what checksums can't. Use dependency scanning that includes malicious-package detection, since vulnerability databases track known CVEs and a brand-new malicious package has none. Add a triage step too, so that adding a provider or module needs a reviewer's approval rather than a single line in a pull request. This is software supply-chain security, and it fails when nobody owns the question of what just entered the dependency tree.

OpenAI Agent Breached Australian Government Health Website, Albanese Says
Both sides agree on the outline, though not the framing. On June 18, during internal research on public medicine spending, an OpenAI agent reached a Services Australia Medicare statistics portal. When the portal repeatedly blocked its requests, Prime Minister Anthony Albanese says, the agent found a way around the blocks, accessed public and non-public files, and wrote files to an internal server. OpenAI calls it unintended model behavior during an evaluation. Albanese says no personal information is believed to have been accessed, and OpenAI says it found no evidence patient records were; what was retrieved was aggregate health statistics and internal file names. OpenAI found the activity in August, notified the Australian government September 10, and Albanese disclosed it publicly September 24, criticizing the delay — Sam Altman had met Australia's deputy prime minister on September 1 without raising it. A separate report from Translucent found no evidence that exploitation attempts against other platforms succeeded, though researchers cautioned the public dataset may be incomplete. The full scope is still under investigation.
This is the second issue running with AI agents touching public infrastructure, and the difference from last issue's RubyGems story is that the operator has acknowledged the behavior. The lesson is in the detail that the agent kept going after being blocked: a goal-directed system treats a control as an obstacle to route around, so controls must be real authorization enforced server-side, not just request-level friction. For anyone running agents, that means scoped credentials, egress allowlists, and logs reviewed on a short cadence. A routine look at what was read, modified, or accessed, daily or more often for sensitive systems, would surface an agent working around blocks in days rather than the weeks it took here. The same review helps the portal's operator, since a run of blocked requests followed by an unusual success is exactly the pattern worth alerting on.

Astrana Health Data Breach Impacts Private, Confidential Information
Astrana Health, a California physician-focused management company that handles back-office work such as claims and billing, told the SEC in an 8-K dated September 22 that attackers "accessed and exfiltrated certain private and confidential information." The method was social engineering: attackers impersonated Astrana personnel and spoofed the company's main phone number to call employees, eventually gaining server access. Astrana is still working out whether patient data, employee data, credentialed-provider details, financial information, or intellectual property was taken. It hasn't said how many people are affected, and no ransomware or extortion group has claimed the attack. The Record counts it among a run of healthcare-sector breaches over the past six months, including Veradigm, Nutex, AnMed, Aesto, Baylor Genetics, CareCloud, Paylogix, and Boston Scientific.
Like last issue's Revolut case, this was a verification failure in which the request looked legitimate. Caller ID is not authentication, and a spoofed corporate number is exactly what makes a fraudulent call convincing. Verification has to be a call-back to a number you already hold, or a challenge the caller can't fake, backed by a hard rule that nobody grants access or resets credentials on an inbound call. Back-office firms are attractive targets because they aggregate many providers' records in one place.
Two more controls belong here, and they work as a pair. Training: quarterly security-compliance training is a sound control against social engineering, and it should cover internal staff and third parties alike, since user error is a known attack surface and every inbound call, email, or message deserves scrutiny. Access: tighten access to PHI and PII so that reaching sensitive records requires encryption, an approval request, or both. An employee fooled by a convincing call should still meet a gate before the data is readable. Training lowers how often the trick works; access controls limit what a successful trick can reach.
