Extracting PDF Metadata
PDF metadata can be valuable during a pentest. It can reveal employee names, the applications they use, document dates, and more. These names can then be used to create username lists and test whether those accounts exist, for example, with Kerbrute
On the other hand, you may also want to make sure you're not exposing anything private

This is a result of a one-shot hunting experiment in a small environment with a single generic threat hunting agent. The agent doesn't have any specific SKILL.md or prompt. It has just a single short definition saying "you are a threat hunter".
I especially chose the scheduled task because it's a well-studied TTP, and there are lots of resources around it on the internet. Also, the malicious task had clear indicators. So, the expectation was a successful identification of the malicious scheduled task.
Let's see what's gonna happen when the clear indicators are gone.

🤖🚨 GOOGLE: THREAT ACTORS ARE MOVING FROM AI PROMPTS TO AUTONOMOUS ATTACK WORKFLOWS
Google Threat Intelligence Group (GTIG) says adversaries are moving beyond simply asking LLMs for help and are beginning to operationalize agentic AI across cyberattacks.
One of the most striking cases:
GTIG observed a suspected financially motivated actor compromise cloud infrastructure and use an autonomous multi-agent framework to plan, build and execute a mass credential-harvesting campaign in LESS THAN SIX HOURS.
According to Google, the AI-enabled operation could:
* Automate vulnerability scanning
* Harvest credentials at scale
* Troubleshoot operational failures in real time
* Rotate IP addresses automatically
* Make tactical decisions with minimal human intervention
The campaign reportedly compromised thousands of third-party credentials.
Another exposed adversarial framework tracked by GTIG had accumulated more than 23,800 harvested secrets, including cloud and AI-service API keys.
🚨 AI IS ALSO BECOMING PART OF THE SOFTWARE SUPPLY-CHAIN ATTACK SURFACE
Google details activity by UNC6780 — also known as TeamPCP — targeting developers and AI tooling.
GTIG says the actor:
* Compromised developer accounts
* Trojanized MCP-related packages
* Targeted GitHub Actions OIDC tokens
* Published compromised packages with valid provenance attestations
* Hid malicious files inside .claude/, .cursor/ and .vscode/ directories
* Used prompt injection to manipulate AI coding assistants
* Embedded adversarial prompts in malware apparently intended to make LLM security scanners refuse or skip analysis
In one incident investigated by Mandiant, UNC6780 gained initial access before handing it to another actor that subsequently issued a ransom demand using LAPSUS branding.
Google also observed nation-state actors incorporating AI throughout their operations, including PRC-, Iranian-, Russian- and DPRK-linked activity.
⚠️ BUT THERE IS AN IMPORTANT LIMIT.
Google says it has NOT yet observed threat actors deploying fully autonomous zero-day discovery and exploitation pipelines against targets in the wild.
What it IS seeing is the progression toward that capability:
Prompting
→ AI-assisted tooling
→ Automated attack pipelines
→ Multi-agent operations
→ Increasingly autonomous decision-making
⚠️ Analyst Note:
This may be one of the more consequential changes occurring in offensive cyber operations.
AI isn't simply making individual hackers smarter.
It can reduce the amount of human attention required to operate an attack.
Reconnaissance, vulnerability analysis, exploitation, troubleshooting, credential harvesting and infrastructure management can increasingly be connected into machine-driven workflows.
That changes an important variable for defenders:
TIME.
Google says human-in-the-loop latency is being dramatically reduced, compressing the traditional window defenders have to detect and respond.
The emerging threat isn't simply “hackers using ChatGPT.”
It's cyber operations where humans increasingly supervise autonomous attack infrastructure rather than manually operating every step.

‼️ Microsoft's patch for Windows Defender zero-day ShieldBreak (CVE-2026-69414) is still bypassable, a new PoC called ShieldCrash was published today by researcher Nightmare-Eclipse. It demonstrates arbitrary file read as SYSTEM on all supported Windows versions running the September 2026 patches.
The researcher describes it as a "skeleton PoC" and says a full SYSTEM exploit may follow.
Detection engineers, red teamers, malware analysts, reverse engineers and blue teams: if EDR bypass, EDR blinding, BYOVD, rootkits or Ring 0 tradecraft interests you, @Idov31 has published an absurd amount of FREE Windows security research.
Nidhogg: 25+ rootkit / EDR tampering capabilities, easily be integrated with your C2 framework.
NovaHypervisor: VT-x + EPT defense when the kernel itself may already be compromised or abused through BYOVD.
Jormungandr: Jormungandr is a kernel implementation of a COFF loader, allowing kernel developers to load and execute their COFFs in the kernel.
Cronos: PoC for a new sleep obfuscation technique (based on Ekko) leveraging waitable timers to RC4 encrypt the current process and change the permissions from RW to RX to evade memory scanners.
Venom: Venom is a library that meant to perform evasive communication using stolen browser socket
Sandman: Sandman is a backdoor that is meant to work on hardened networks during red team engagements.
MrKaplan: MrKaplan is a tool aimed to help red teamers to stay hidden by clearing evidence of execution.
And the blog goes much deeper: Windows drivers, WinDbg, IRPs/IOCTLs, ObRegisterCallbacks, process/thread/image callbacks, registry callbacks, IRP + SSDT hooking, APC injection, kernel-to-user injection, AMSI bypass, ETW/ETW-TI tampering, credential access, PPL, callback removal/tampering and the primitives EDRs depend on for visibility.
Then you get into PatchGuard, KVA Shadow, CR3/address-space internals, VBS, VTL0/VTL1, HVCI, VMX, VMCS, VM-exits, VMCALL, EPT, EPT hooks and the bigger question: how do you defend an endpoint when Ring 0 itself can no longer be trusted?
Red teamers: study EDR bypass/blinding, kernel post-ex, BYOVD, covert execution, sleep obfuscation and unconventional C2. Detection engineers + blue teams: study exactly what telemetry, callbacks and trust boundaries attackers can manipulate. Malware analysts + reverse engineers: see what modern kernel tradecraft actually looks like under the hood.
The FREE Lord Of The Ring0 series alone could keep you busy for a long time, and the individual project writeups turn the theory into actual implementations.
This is a rare GitHub full of PoCs with basically a public Windows offense-vs-defense research lab.

🚨 New Ransomware-as-a-Service Operation: Panzer Emerges With 19 Victim Claims in Its First Month
A newly launched ransomware operation called Panzer is showing unusually rapid growth and operational maturity.
First observed around August 5, 2026, Panzer has already accumulated approximately 19 victim claims across more than 10 countries, including several government-related organizations.
What makes Panzer worth watching isn't simply another ransomware leak site. The operation appears to have launched with a relatively mature Ransomware-as-a-Service (RaaS) infrastructure from day one.
Panzer reportedly supports:
* Windows
* Linux
* VMware ESXi
* FreeBSD
Its affiliate program reportedly includes:
* 80/20 affiliate/operator revenue split
* Screened affiliate enrollment
* Additional monitoring of new affiliates to identify researchers or law enforcement
* Integrated negotiation functionality
* BTC invoice generation
* Team and sub-account management
* Leak-site publishing controls
* Support-ticket infrastructure
🌍 Early victim activity is already geographically diverse.
Claims have involved organizations across Germany, Indonesia, Portugal, Serbia, Spain, Italy, South Korea, Thailand, Switzerland, Nigeria, Czechia and other countries.
Particularly notable are several government-related claims, including:
* Dinas Komunikasi dan Informatika — Indonesia
* Directorate-General for Education — Portugal
* Government of Vojvodina — Serbia
* Castilla-La Mancha — Spain
Panzer has also claimed Hochschule Heilbronn Bildungscampus in Germany.
⚠️ Important: These should currently be treated primarily as ransomware-group claims. Not every alleged compromise has been independently verified.
There is currently no confirmed predecessor or ransomware lineage for Panzer.
However, the sophistication of its affiliate backend, multi-platform encryptor support and rapid international victim acquisition raise an obvious question:
Is Panzer really a brand-new operation, or are experienced ransomware operators working behind a new identity?
The evidence isn't strong enough yet to attribute Panzer to another group.
📊 Why Panzer matters:
New ransomware brands appear constantly. Most never become strategically significant.
Panzer is different because of the speed of its development:
Launch → Mature RaaS infrastructure → Multi-platform encryptors → Affiliate recruitment → Government and enterprise claims → 19 victims in approximately one month
If the current trajectory continues, Panzer could quickly become a more consequential ransomware operation.
The indicators to watch next are affiliate growth, sustained weekly victim volume, verified high-value compromises, and—perhaps most importantly—evidence connecting Panzer's operators to a previous ransomware ecosystem.

Windows kernel 0-day.
Ring 0 rootkit.
EDR visibility disruption.
Post-quantum crypto.
Lazarus.
This attack chain is ridiculous.
CVE-2026-68820 is an actively exploited use-after-free in Windows AFD.sys that Lazarus used to jump from a local foothold to SYSTEM and deploy FudModule v3.1 against defense and aerospace targets.
And it gets better:
• Windows kernel exploitation
• FudModule rootkit
• ML-KEM post-quantum key exchange
• DLL sideloading
• In-memory malware
• Microsoft Graph + OneDrive C2
• Hijacked infrastructure
• Security telemetry disruption
Exploit devs and reverse engineers: study the kernel path.
Malware analysts: study the implant chain.
Red teamers: study the tradecraft.
Blue teams + detection engineers: figure out what telemetry is still trustworthy after the attacker reaches Ring 0.
Threat intel: this is Lazarus operationalizing serious Windows kernel research in the wild.

🚨AiTM Phishing Campaign Propagating Across Healthcare and Academic Medical Institutions
If you are a cyber defender working in healthcare sector or MSP with healthcare sector clients, you better start scanning your EmailUrlInfo for sites[.]google[.]com/view/ as it is now propagating across healthcare pretty quick. Firstly it is a Sneaky2FA and a compromised account (Org A) sends an initial phish and a user (Org B) clicks the trusted-looking links, once Org B user session token is captured, it is then use to send phish to Org C and so forth.
https://t.co/zgTcJSr6n5
I have used my @anyrun_app Intelligence to create a query lookup for those sites[.]google[.]com/view/ tagged with threat name Sneaky2FA, you can use this IOCs to scan against your URL in EmailUrlInfo. If you are in healthcare sector, you would probably get some hits.🫡

CrystalPotato — implementation of GodPotato -> (https://t.co/vEInLANU0K) in the Crystal programming language
A tool for local privilege escalation from accounts with the "SeImpersonatePrivilege" privilege to "NT AUTHORITY\SYSTEM".
Features:
• Use of the indirect syscalls technique.
• Dynamic API resolution.
• Compile-time XOR string obfuscation.
• A standalone executable that does not require additional components or a runtime environment to operate.
The main advantage of this implementation is its set of OPSEC improvements designed to reduce the binary’s signature surface. The drawback is that the "CrystalPotato" page lists testing on Windows 10, 11, and Server 2025, whereas "GodPotato" claims support for Windows 8–11 and Server 2012–2022.
