Fox-IT (NCC Group) details RemotePE, a North-Korean Lazarus in-memory RAT delivered through a three-stage chain — DPAPILoader (environmentally-keyed first-stage), RemotePELoader (HellsGate / ETW-patched HTTP beacon) and RemotePE itself, which never touches disk. The writeup walks AES-GCM C2, MSZIP-compressed command batches, the IConsole / IFileExplorer / IProcess command surface, infrastructure, MITRE ATT&CK mapping, and a full IOC set spanning July 2023 — May 2026.
CVE-2026-6068 — NASM Heap UAF Turns Into Persistent RCE Through a Dependency-File Symlink Trick
A heap use-after-free in NASM’s response-file parser (CVE-2026-6068) sounds boring — until the dangling pointer is reused as a filename for fopen(). Project SEKAI’s breakingbad turns it into a deterministic, supply-chain-style persistent RCE that overwrites the victim’s ~/.bashrc through a 120-character heap-spray label, a shipped symlink, and the unescaped shell metacharacters in NASM’s Makefile-style dependency output. No ASLR, NX, PIE, RELRO or stack-canary bypass needed. Still unpatched at disclosure.
Roundcube CVE-2025-49113: Authenticated PHP Object Deserialization to RCE in Open-Source Webmail
CVE-2025-49113 is a critical authenticated remote-code-execution flaw in Roundcube webmail — the default in cPanel, Plesk, and many hosting stacks — caused by insufficient validation of the _from upload parameter that lets attackers inject malicious PHP-serialized objects into session storage. The bug went undetected for nearly a decade and reportedly exposes more than 53 million hosts across all Roundcube 1.1.0–1.6.10 builds.
TREVEX: Black-Box CPU Fuzzing Finds FP-DSS, New FPVI Variants, and Zero-at-ret
TREVEX is a post-silicon black-box CPU fuzzer from CISPA designed to discover data-flow transient execution vulnerabilities without needing RTL access, an ISA emulator, or a leakage contract. The framework runs across 20 microarchitectures from Intel, AMD, and Zhaoxin and uncovers a new TEA — Floating Point Divider State Sampling (FP-DSS, CVE-2025-54505) — on AMD Zen and Zen+, a new FPVI variant on AMD that does not need denormal inputs, three instances of Zero-at-ret on Intel, and FPVI on Zhaoxin. The authors weaponise FP-DSS from native code, the Linux kernel, and a Chrome JavaScript exploit.

CVE-2025-54539: Apache.NMS.AMQP Deserialization Policy Bypass to Unauthenticated RCE in .NET
CVE-2025-54539 is a deserialization policy bypass in Apache.NMS.AMQP (≤ 2.3.0) that lets a single 290-byte AMQP message reach BinaryFormatter inside an unsuspecting .NET client and execute arbitrary commands.
mov ax, bx drama story – for fun and fasm
A tiny funny FASM program for Windows where BX generously shares its value with AX using mov ax, bx, turning a simple register copy into a dramatic love story with a MessageBox punchline.
APC Tandem: A Primitive-Chaining Process Injection That Slips Past Common EDR Triggers
A walkthrough of “APC Tandem”, a stealth Windows process-injection technique that replaces WriteProcessMemory, CreateRemoteThread and VirtualAllocEx with a chain of less-watched primitives — thread description smuggling, paired GetThreadDescription/RtlMoveMemory APCs, and a Special User APC for execution.
Fundamentals of Virtual Memory: A Deep Dive into Paging, Page Tables, and Process Address Spaces
A structured walkthrough of how virtual memory really works on modern operating systems — from contiguous allocation and external fragmentation to paging, page tables, demand paging, stack and heap layout, mmap and copy-on-write. Based on and credited to “Fundamental of Virtual Memory” on the Melatoni blog (nghiant3223.github.io).
Essential iOS Hardening: A Practical Guide to Defending iPhones Against Modern Spyware
A practical, security-engineering view of the essential iOS hardening steps every iPhone user — and especially high-risk targets — should apply: Lockdown Mode, Advanced Data Protection, attack-surface reduction, deep reboots, and detection with tooling like iVerify. Based on and credited to “Essential iOS Hardening Steps” by Officer’s Notes, published on Medium (Technology Hits).
