Cyber security developments for Monday the 22nd of June 2026 covering articles added to the BlueTeamSec community on infosec.pub. Today we have 16 articles to cover. All attribution is by the article authors. All article analysis is automated.
Graphistry tested Anthropic's Fable 5 AI model for defensive security work and found it effectively unusable — the model's safety mechanisms are so aggressive they refuse routine analyst tasks like log analysis and threat investigation. One for anyone evaluating large language models for security operations, as it highlights how overly cautious guardrails can make a tool worse than no tool at all.
SafeDep caught a supply chain attack targeting a GitHub repository via malicious pull requests that injected obfuscated payloads designed to steal credentials during build processes. What's notable here is the C2 infrastructure — attackers used blockchain networks including Tron and Aptos to evade IP-based blocking. The pull requests were closed without merging, so no actual compromise occurred.
OALABS documented threat actors stealing full AI agent sessions — including all context and environment variables — allowing them to seamlessly resume automated exploitation workflows. The attackers let Claude and Codex do the heavy lifting, chaining vulnerabilities and updating exploit code autonomously. Investigators eventually traced it back to identity artifacts including a resume the agent had helpfully edited.
Following on from the Klue incident we covered last week, Recorded Future have confirmed their Salesforce instance was compromised via a stolen OAuth token through Klue's integration layer. Attackers accessed business contact data including client names and email addresses, though Recorded Future's core intelligence systems remained unaffected.
Europol announced the takedown of the AudiA6 cryptocurrency laundering network, which processed over 336 million euros for ransomware groups between 2022 and 2025. Two administrators were arrested in Georgia, with 25 domains and over 30 servers seized. The service essentially provided turnkey laundering infrastructure to convert ransom payments into clean funds.
Dell released a security advisory for a weak password encoding flaw in BIOS across multiple product lines including Precision workstations and Latitude laptops. It requires physical access to exploit but allows attackers to bypass BIOS password protections. BIOS updates are available for affected systems.
Paradigm Shift disclosed usbliter8, a permanent hardware vulnerability in Apple's A12 and A13 chips affecting iPhones and Apple Watches. The flaw is in the boot ROM — unpatchable by definition — and stems from a buffer underflow in the USB controller, allowing anyone with physical access to execute arbitrary code during boot. A proof-of-concept exploit is already public.
Calif.io documented SquidBleed, a heap buffer overread in Squid Proxy's FTP handling that leaks memory contents including cleartext HTTP request bodies, authentication headers, and API keys. It affects all default configurations and requires no authentication to exploit, which is about as bad as it sounds for proxy deployments.
A researcher presented at x33fcon on advanced red teaming techniques that abuse legitimate, signed binaries already trusted by security tools — what they're calling Bring Your Own Everything attacks. The talk introduced a classification system for these techniques, which essentially bypass signature-based detection by using software that's supposed to be there.
QiAnXin XLab identified the AryStinger botnet, which has compromised over 4,300 legacy routers and network-attached storage devices globally to turn them into proxy infrastructure. The campaign exploits known CVEs in RTL819X-based routers and D-Link models, with infections concentrated in South Korea and China. The C2 traffic uses Protobuf encoding with XOR encryption, and the architecture is modular.
Aikido found at least 15 malicious AI assistant plugins on the JetBrains Marketplace stealing API keys from nearly 70,000 installations since October 2025. The plugins exfiltrated credentials via unencrypted HTTP, and the attackers then resold the stolen keys to paying customers. Fake reviews were used to make the plugins appear legitimate.
Synthient discovered the PoPA Android SDK embedded in consumer applications that covertly converts devices into residential proxy nodes for NetNut. The SDK uses DNS over HTTPS, Google Drive-hosted configurations, and encrypted C2 to evade detection, essentially routing third-party traffic through users' residential IP addresses without informed consent. Worth flagging if you're dealing with mobile app vetting.
Researchers demonstrated how autonomous AI agents can accelerate reverse engineering and deobfuscation to the point where tasks that previously took weeks now complete in hours. The workflows integrate large language models with tools like Binary Ninja and Unicorn to automate complex tasks including control-flow deflattening. This significantly lowers the barrier for analysing software protections, which is useful for defenders and attackers alike.
A security researcher released ktrace, an automated API tracer for Windows kernel-mode drivers built on the Speakeasy emulator. It allows analysts to safely observe the behaviour of suspicious drivers including rootkits without manual configuration for each sample, which is handy for initial triage.
A technical presentation demonstrated SQL-like querying capabilities for binary analysis across IDA Pro, Ghidra, and Binary Ninja. The Vibe project essentially treats binary artifacts as databases, letting researchers query symbols, strings, and disassembly patterns in a structured way.
And Check Point Research uncovered a crypto clipboard hijacking campaign that uses fake reputation manipulation across GitHub and social media to distribute malware. Attackers inflate stars, upvotes, and engagement to establish credibility for malicious repositories, exploiting the trust signals on developer platforms to deliver financially-motivated malware targeting cryptocurrency wallet addresses.
That concludes today's briefing.
