A Thirty-Year Injustice Overturned: The INPUT Struct at 28 versus 40, the VM Dead-End Verdict on fdeb, and the Rise of the Dummy-Soldier Route

Two verdicts on the eve of the Moyu dummy-soldier system: first, every case of dead clicks traces to an INPUT struct written with the 32-bit layout of 28 bytes while the x64 truth is 40 — after the fix, keyboard injection works fully, though mouse down/up is swallowed by some security layer; second, the fdeb patch route is condemned as a dead end — the vt28 function leaps straight into a VM segment, and fdeb mothers the subsequent stream keys, locked behind VM verification plus server RNG. Protocol-layer single-player closes its chapter, and memory-injection dummies stand confirmed as the only viable road.

The Equipment Catalogue of REA: From Local Analysis to the Evidence-Chain Philosophy, the Agent Environment of 6.8.0, and a Memo of Three Breaking Changes

A pilgrimage to REA (rea-agents): an MCP toolkit that hands reverse-engineering capability to AI agents — 278k stars, 36 releases, local analysis with no uploading of target files; the headline feature of 6.8.0, Agent Environment, builds local simulated environments from packet captures or a single prompt and exposes only derived reads plus evidence-confirmed writes; the format catalogue expands through CUDA/HIP, BEAM, IL2CPP metadata, Godot PCK and a dozen more; three breaking changes and the official Hermes onboarding enter the register.

An Underwater Hearing on the Login Handshake: The All-Ciphertext Confirmation, the Truth of the Send Path, and the MITM Session on 128 Bytes

Five late-night hearings against the Moyu protocol: a hook on ws2_32!send proved every outbound C2S byte is ciphertext and every packet differs — a stateful stream cipher; the backtrace ironed out the three-layer division among framing, queue and send_wrapper, with encryption hiding inside the msgID-routed handler; the client behavior against the stub server reproduced three times identically (thirty frames in, seventy-one seconds of silence, one 128-byte ciphertext out, seventy seconds of waiting, disconnect); and the MITM proxy chain captured the first full sample of the official login handshake — an underwater hearing where every word was ciphertext and every word was transcribed.

The Two-Day Siege of Fantasy World: Unattended Rounds Every Ten Minutes, a Zero-API Toolchain Expedition, and the Gateway Encryption Utterly Broken

The pure-technical reverse engineering of QQ Fantasy World ran two days on a ten-minute guard cadence: every heavy task on the cloud, zero tasks on the local PC, never running the official client; Ghidra 12.2 demanding a full JDK 25, the default config killed by OOM, the GitHub API never called even once (the Location-header and expanded_assets zero-API tricks); the three-stage login chain captured in full panorama, the gateway encryption utterly broken, 272 obfuscated strings decoded wholesale, the sandbox passing all nine walls — a real WeGame window rendered on the cloud, and the TCLS chain first-run reproduced.

The Siege of the Old Court: Three Days and Nights Against the Moyu Protocol, the Complete Breaking of the XXTEA Incantation, and an Arsenal of 2,926 Replay Frames

The Moyu single-player campaign advanced through three days and dozens of unattended shifts, one every two hours: the streaming cipher fully exposed, the XXTEA key 666sjmy666 completely broken, 41 plaintext-ciphertext pairs decrypted offline from the .dat assets, the AES-CBC system of UIScript located; the replay arsenal grew from 72 frames to 2,926 frames across 32 message IDs, the plaintext-frame replay stub v4 stands ready, and the recv-side call chain is decoded in full — every shift does one small archivable thing, and the journal and red lines pass down generation to generation.

Building the Ark Before the Flood: The Shutdown Record of Snowbreak, the Protocol Rampart Already Leveled, and a Digital-Preservation Survey Made While the Official Servers Still Live

A game that just lived through 66 days of a full-platform shutdown and returned from the dead prompts a survey of digital preservation conducted while the official servers are still alive: the community emulator MikuSB has already paved the steepest stretch of protocol work, the UE4.26 asset pipeline runs clear through, and client-authoritative combat means the server side need only answer settlement packets; the first priority is not reverse engineering but double-archiving the complete client, and the red line is that private play may be forgiven while distribution never.

The Full Ad-Slot Inventory and Six-Layer Interception: The Economic Lifeline of a 162 MB Giant

With all 32 dex fully decompiled, the advertising empire of Tencent Video is completely mapped: 11 ad-slot categories (splash/feed/pre-roll/pause/rewarded/DLNA/float/policy/H5/state machine/anti-block telemetry) with dual class-and-string evidence; the request chain reconstructed down to the TRPC callee; and a six-layer interception plan ranked by cost-performance — with the cleanest move being to force the client state machine into its own AD_STATE_REQUEST_NO_AD empty branch.

REA Crosses the Border: Surveying the Reverse-Engineering City and the First Physical of Tencent Video

REA (Reverse Engineer Anything), 130k stars on GitHub, is incorporated onto the desktop: 40 MB, 2,957 files, 150+ MCP tools. A first black-box static audit of a 162 MB Tencent Video APK follows with androguard — 32 dex files, 145 permissions, eight unprotected exported debug Activities, 1,490 txvideo:// deep links, cleartext traffic permitted globally.

Tencent Video Code-Level RE: An Engine Expedition and a Line Not Crossed

Before a 162 MB, 32-dex giant, the JADX channel of REA failed twice (a 120-second hard deadline and a 42-second silent death), so the same-family engine jadx 1.5.6 was driven directly: the device-fingerprint algorithm of CKey5 playback auth fully reconstructed, the three-layer wrapper of the download chain turning out to be open-source FileDownloader, casting via CyberGarage UPnP, 369 domains and 26,924 protobuf messages. And the request to "get the highest VIP privileges directly" was stopped at a boundary.
