'WhiteCobra' floods VSCode market with crypto-stealing extensions

A threat actor named WhiteCobra has targeting VSCode, Cursor, and Windsurf users by planting 24 malicious extensions in the Visual Studio marketplace and the Open VSX registry. The campaign is ongoing as the threat actor continuously uploads new malicious code to replace the extensions that are removed. In a public post, core Ethereum developer Zak Cole described how his wallet was drained after using a seemingly legitimate extension (contractshark.solidity-lang) for Cursor code editor. Cole

How Ruby executes JIT code

Ever since YJIT’s introduction, I’ve felt simultaneously close to and distant from Ruby’s JIT compiler. I know how to enable it in my Ruby programs. I know it makes my Ruby programs run faster by compiling some of them into machine code. But my understanding around YJIT, or JIT compilers in Ruby in general, seems to end here. A few months ago, my colleague Max Bernstein wrote ZJIT has been merged into Ruby to explain how ZJIT compiles Ruby’s bytecode to HIR, LIR, and then to native code. It she

Hackers exploited Sitecore zero-day flaw to deploy backdoors

Threat actors have been exploiting a zero-day vulnerability in legacy Sitecore deployments to deploy WeepSteel reconnaissance malware. The flaw, tracked under CVE-2025-53690, is a ViewState deserialization vulnerability caused by the inclusion of a sample ASP.NET machine key in pre-2017 Sitecore guides. Some customers reused this key in production, allowing attackers with knowledge of the key to craft valid, but malicious '_VIEWSTATE' payloads that tricked the server into deserializing and exe

A Fast Bytecode VM for Arithmetic: The Compiler

In this post, we write the compiler for our AST to bytecode, and a decompiler for the bytecode. In this series of posts, we write a fast bytecode compiler and a virtual machine for arithmetic in Haskell. We explore the following topics: In this series of posts, we write a fast bytecode compiler and a virtual machine for arithmetic in Haskell. We explore the following topics: Parsing arithmetic expressions to Abstract Syntax Trees (ASTs). Unit testing for our parser. Interpreting ASTs. Comp

Out-Fibbing CPython with the Plush Interpreter

Out-Fibbing CPython with the Plush Interpreter In the last post I talked about Plush, the toy programming language with actor-based parallelism I've been tinkering with. The implementation is still immature, but it's reached a point where I can write fun programs that produce 2D/3D graphics and parallelize things over multiple CPU cores. Something I'd like to try soon, for the fun of it, is to animate a spinning cube with software rendering (rasterization). Before I get to that though, I'd like

iPhone maker Foxconn joins $1 trillion AI data center market with new alliance

Foxconn on Wednesday said it is taking a stake in TECO Electric & Machinery Co ., as it looks to supercharge its efforts to become a key player in building artificial intelligence data centers. The Taiwanese firm, formally known as Hon Hai, is looking to replicate the success it has had in consumer electronics in the world of AI. It's a play that could unlock Foxconn's access to a potential $1 trillion of spending by companies on data centers in the coming years, according to Counterpoint Resea

Pluto is a unique dialect of Lua with a focus on general-purpose programming

Why should you choose Pluto? Accelerated Development. Greatly enhanced standard library. Several new syntaxes, such as switch statements, compound operators, ternary expressions, etc. Focused On Lua Compatibility. Pluto is largely compatible with Lua 5.4 source code, but there is an imperfection: Pluto implements new keywords, which can cause conflicts with otherwise normal identifiers such as 'switch', or 'class'. The parser tries to identify what is meant but if that doesn't work, you ca

Why I recommend this power bank to most iPhone users - especially if you travel often

ZDNET's key takeaways The Nitecore NW5000 has an ultralight and ultrathin design that blends into the iPhone. It has a 5,000mAh capacity that's just enough to fully charge any iPhone model (and some more). You'll have to pay a premium for this accessory, but its build quality justifies it. $69.95 at Amazon I find that rather than complaining about the iPhone's poor battery life, I prefer to do something about it. This is why my iPhone is almost always rocking with a magnetic power bank attach

Sitecore CMS exploit chain starts with hardcoded 'b' password

A chain of Sitecore Experience Platform (XP) vulnerabilities allows attackers to perform remote code execution (RCE) without authentication to breach and hijack servers. Sitecore is a popular enterprise CMS used by businesses to create and manage content across websites and digital media. Discovered by watchTowr researchers, the pre-auth RCE chain disclosed today consists of three distinct vulnerabilities. It hinges on the presence of an internal user (sitecore\ServicesAPI) with a hardcoded pa
