The article details an AI‑crafted C2 remote‑access trojan framework hosted at 101.32.128[.]36:8443, describing its Go implant, Python listener, PowerShell stager, custom 443‑based encryption, Telegram bot exfiltration, the payload delivery chain via paste.rs and GitHub Gist, and provides sample hashes for the binaries.
This article explains how HotSpot's C1 and C2 JIT compiler threads work, why they can consume excessive CPU, and provides practical JVM tuning options—including tiered compilation, code‑cache sizing, and compiler‑thread adjustments—to mitigate performance issues.
Researchers from 360 Netlab have uncovered RotaJakiro, a stealthy Linux backdoor malware first seen in 2018, which uses ZLIB compression, AES/XOR/ROTATE encryption, and hidden plugins to exfiltrate data and evade detection, with twelve functions yet its true purpose remains unknown.
This article explains Java's explicit null checks, introduces the JVM's implicit null check mechanism via ImplicitNullCheckStub, and details how the C1 and C2 compilers perform null‑check elimination using data‑flow analysis and SSA, highlighting performance implications and optimization strategies.
