Compiling Perl to WebAssembly: A Herculean Task

Building a startup, the author faced a challenge: client-side file metadata extraction. ExifTool, while powerful, proved difficult to statically compile and deploy across OSes due to its Perl nature. Various approaches were attempted, including statically compiling Perl, finally leading to WebAssembly. The journey was fraught with challenges, battling Perl's build system, Emscripten, and WASI, even requiring Perl source code modifications. The author successfully built a self-contained WebAssembly Perl running ExifTool, but the process exposed insufficient exception handling support in WebAssembly runtimes.

Breaking WebAssembly Runtime Limitations: Asyncifying ZeroPerl

Frustrated by the lack of exnref support in most WebAssembly runtimes, rendering ZeroPerl unusable, the author decided to fix the problem instead of complaining. By leveraging Binaryen's Asyncify feature, a replacement for setjmp was implemented from scratch, bypassing libsetjmp's compatibility issues. After removing the official library, writing assembly code, and optimizing with wasm-opt, ZeroPerl now runs successfully in Wasmer, Wasmtime, and other WebAssembly runtimes. This breakthrough delivers a fully sandboxed and self-contained Perl WebAssembly module.

Systemd to Boot Directly from HTTP-Downloaded Disk Images

2025-02-11

Systemd lead developer Lennart Poettering is adding the ability to boot directly from a disk image downloaded via HTTP within the initial RAM disk (initrd) during the Linux boot process. Building on recent systemd additions, this allows downloading the root disk image via HTTP, attaching it to a loopback device, and mounting it. The goal is to allow pointing UEFI to a URL to load the Unified Kernel Image (UKI) and boot the root filesystem. The immediate use case is simplifying physical device testing by easily booting new root filesystems over HTTP on each boot. The work-in-progress pull request includes the initial code for this; future extensions may include NVMe-over-TCP support.

Malicious VS Code Extension Uses Typosquatting to Deliver Multi-Stage Malware

Researchers uncovered a malicious VS Code extension, `truffelvscode`, which typosquatted the popular `truffle` extension. This extension acts as a Trojan horse for multi-stage malware. The malware downloads and executes several stages of malicious code, ultimately installing and configuring the ScreenConnect remote access tool, granting attackers remote control of the compromised system. Obfuscation techniques were used to hide the malicious code, but researchers used deobfuscation and sandbox analysis to reveal the entire attack chain. This incident highlights the importance of caution when installing VS Code extensions and underscores the growing threat of software supply chain attacks.
