Mixed Boolean-Arithmetic (MBA) obfuscation disguises simple operations like x + y behind tangles of arithmetic and bitwise operators. Malware authors and software protectors rely on it because no standard simplification technique covers both domains simultaneously; algebraic simplifiers don’t understand bitwise logic, and Boolean minimizers can’t handle arithmetic. We’re releasing CoBRA, an [...]
This is for new routers; you don’t have to throw away your existing ones: The Executive Branch determination noted that foreign-produced routers (1) introduce “a supply chain vulnerability that could disrupt the U.S. economy, critical infrastructure, and national defense” and (2) pose “a severe cybersecurity risk that could be leveraged to immediately and severely disrupt U [...]
Posted by Adam Gavish, Google GenAI Security TeamIndirect prompt injection (IPI) is an evolving threat vector targeting users of complex AI applications with multiple data sources, such as Workspace with Gemini. This technique enables the attacker to influence the behavior of an LLM by injecting malicious instructions into the data or tools used by the LLM as it completes the user’s query. This ma [...]
Wired writes (alternate source): Security researchers at Google on Tuesday released a report describing what they’re calling “Coruna,” a highly sophisticated iPhone hacking toolkit that includes five complete hacking techniques capable of bypassing all the defenses of an iPhone to silently install malware on a device when it visits a website containing the exploitation code. In t [...]
The 2026 US “Cyber Strategy for America” document is mostly the same thing we’ve seen out of the White House for over a decade, but with a more aggressive tone. But one sentence stood out: “We will unleash the private sector by creating incentives to identify and disrupt adversary networks and scale our national capabilities.” This sounds like a call for hackback: giv [...]
Code coverage is one of the most dangerous quality metrics in software testing. Many developers fail to realize that code coverage lies by omission: it measures execution, not verification. Test suites with high coverage can obfuscate the fact that critical functionality is untested as software develops over time. We saw this when mutation testing uncovered a high-severity Arkis protocol vulnerabi [...]
Last week, I listened to a fascinating talk by K. Melton on cognitive security, cognitive hacking, and reality pentesting. The slides from the talk are here, but—even better—Menton has a long essay laying out the basic concepts and ideas. The whole thing is important and well worth reading, and I hesitate to excerpt. Here’s a taste: The NeuroCompiler is where raw sensory data get [...]
In March 2026, we ran BugQuest, a 31-day campaign covering everything you need to know about finding and exploiting broken access control vulnerabilities. From understanding the basics of authentication and authorization to spotting subtle authorization bypasses in real code, we broke down one of the most critical vulnerability classes in modern web applications. Broken access controls have consis [...]

Since then, he’s always worked in and around cybersecurity. He’s had roles as a computer science teacher, a technology manager, a [...]
A thoughtful review of Apple’s system to alert users that the camera is on. It’s really well-designed, and important in a world where malware could surreptitiously start recording.

Using dimensional analysis, you can categorically rule out a whole category of logic and arithmetic bugs that plague DeFi formulas. No code changes required, just better reasoning! One of the first lessons in physics is learning to think in terms of dimensions. Physicists can often spot a flawed formula in seconds just by checking whether the dimensions make sense. I once had a teacher who even ke [...]

Broken access control vulnerabilities have consistently remained at the top of the OWASP Top 10, and for a good reason. As web applications continue to grow in complexity, with the introduction of role-based access controls, multi-tenant support, and granular permission models, the likelihood of access control flaws increases significantly. Unlike other vulnerability classes that often rely on ins [...]

AI systems are no longer just isolated models responding to human prompts. In modern production environments, they are increasingly chained together – delegating tasks, calling tools, and coordinating decisions with limited or no human oversight. Almost all that communication happens through APIs. This shift offers enormous productivity benefits. But it has also complicated secu [...]
Account abstraction transforms fixed “private key can do anything” models into programmable systems that enable batching, recovery and spending limits, and flexible gas payment. But that programmability introduces risks: a single bug can be as catastrophic as leaking a private key. After auditing dozens of ERC‑4337 smart accounts, we’ve identified six vulnerability patterns that frequently appear. [...]
