A security researcher released the YellowKey proof‑of‑concept showing that, on Windows 11 and Server 2022/2025, BitLocker can be bypassed without a password or recovery key by using a crafted USB and multiple reboots, sparking accusations that Microsoft may have embedded a backdoor in the WinRE component.
This article highlights four recent GitHub projects—YellowKey exposing a Windows 11 Bitlocker bypass, Clawdmeter delivering an ESP32‑S3 desktop dashboard for Claude Code usage, Pixal3D enabling single‑image 3D asset creation, and a‑stock‑data providing a comprehensive AI‑driven A‑share data toolkit—detailing their core mechanisms, hardware/software specs, and quick‑start instructions.
A detailed walkthrough shows how a low‑skill ransomware written in E‑Language was dissected in a VMware VM, revealing hard‑coded admin credentials, simple command‑line user creation, and a plaintext ransom password, followed by practical removal tips such as Safe Mode and bootable USB cleanup.
This article details a step‑by‑step incident‑response case study of a Windows internal‑network Trojan that exploited SMB port 445, describing how alerts were identified, malicious processes were traced, terminated, and fully removed using tools such as netstat, PChunter, and process monitoring utilities.
This article explains the novel Ctrl‑Inject method that leverages the console Ctrl‑signal handling mechanism to inject code into Windows console processes, detailing its inner workings, pointer‑encoding and CFG bypasses, and the steps required to trigger and clean up the injection.
The Petya ransomware, spreading across Europe and affecting over 80 companies in Russia and Ukraine, leverages the CVE‑2017‑0199 RTF vulnerability for phishing and the MS17‑010 SMB flaw for internal propagation, encrypts the MFT to render systems unbootable, and can be mitigated by applying Windows patches, using strong passwords, and backing up data.
