Argus & the visual overhaul

The biggest single drop since 0.5.0. Triton finally has a real character β€” a 96x96 Argus mood sprite that watches every handshake and shifts mood live. Six full themes (POSEIDON / MATRIX / E-INK / SYNTHWAVE / PHANTOM / BLOOD). Seven idle screensavers keyed off the active theme. Carousel menu style with cyberpunk pictographs. Ambient procedural motion painted behind every menu draw. The whole device feels alive.

Argus β€” Triton's mood sprite

Twelve mood portraits (Watching, Pleased, Annoyed, Resigned, Calculating, Old Fury, Sleeping, Reflective…). Mood-mapped to hunt state β€” Argus sleeps when idle, gets pleased on catch, fully unhinged on Feral burst. Sprite is cached to internal SRAM to dodge MMU stalls during raw-TX.

v0.6 Β· CHARACTER

Six themes + carousel menu

POSEIDON, MATRIX, E-INK, SYNTHWAVE, PHANTOM, BLOOD. Magenta splashes across the dashboard chrome, matrix rain on a 4x speed-up, ambient procedural motion painted under every screen. Carousel menu style toggles in System β€” big-card single-focus with pictograph icons.

v0.6 Β· LOOK

Raw-IDF AP path

Bruce's pinned libnet80211.a crashes Arduino's WiFi.softAP() in ieee80211_hostap_attach +0x2c. New path bypasses Arduino entirely β€” esp_bt_controller_mem_release(BTDM) β†’ raw netif β†’ 4/16 buffer init β†’ esp_wifi_set_config(WIFI_IF_AP) β†’ post-start channel set. Portal, Beacon Spam, Evil Twin all back on-air.

v0.6 Β· WIFI

7 idle screensavers

Sonar sweep, port scan, hex cascade, terminal crack, neural arc, glitch BSOD, tide waves. Kicks in at 2 min idle, pulled from a pool keyed off the active theme. Pick your favorite at System β†’ Screensaver.

v0.6 Β· IDLE

BLE cooperative tick

Sour Apple, Spam, Karma, Flood, FindMy refactored from xTaskCreate (silent rc=-1 because NimBLE eats 4 KB of heap) to cooperative ticks called from each feature's UI loop. Every nearby phone now sees the spam. Confirmed against iOS + Android.

v0.6 Β· BLE

C5 protocol v3 + terminator fix

TRIDENT C5 satellite jumps to wire protocol v3 β€” 9 new commands (clients hunt, beacon spam, probe sniff, deauth detect, karma, AP clone, spectrum, CIW). Critical fix: C5 now sends a zero-payload terminator when a scan finishes so POSEIDON stops spinning forever on empty results.

v0.6 Β· C5

Plus IR LED polarity finally fixed (active-HIGH, not active-LOW), Samsung remote codes verified against Flipper-IRDB, Evil Twin, AP Signal Test, BLE BlueDucky, SATCOM Tracker, Drone Remote ID, Surveillance Hunter, Defensive Monitor, and four nRF52 hat features. Full changelog on GitHub.

SaltyJack β€” the LAN arsenal

Press j from the root menu. Full wired/wireless LAN attack suite with a pirate UX β€” DHCP starvation, rogue DHCP (STA + AP), Responder (LLMNR/NBT-NS/SMB), WPAD PAC harvest, on-device NTLMv2 cracker. No PC tether. No Pi server. Pocket-sized.

@7h30th3r0n3
β˜… BIG HOMAGE Β· SALTYJACK'S ORIGINAL ARCHITECT

@7h30th3r0n3

SaltyJack is a direct port, not inspiration. Every attack module β€” DHCP starve, rogue DHCP, Responder, WPAD, NTLMv2 cracker β€” is a reforge of the work 7h30th3r0n3 shipped first on the Pi (RaspyJack) and on Cardputer (Evil-M5Project / Evil-Cardputer). We reorganized the code into POSEIDON's style, added a pirate sprite pack, built a custom renderer. The attacks themselves β€” protocol framing, timing, pool-exhaustion detection, hashcat 5600 output path β€” that's all 7h30th3r0n3. Go star both repos. Seriously.

What's inside

Six modules behind one menu key. Phase 1 shipped in v0.3; phase 2 lands with v0.4.

DHCP Starvation

Floods the network's DHCP server with random-MAC Discover/Request cycles until the pool exhausts. Live counters. Auto-detects exhaustion on NAK β‰₯ 20.

PHASE 1

Rogue DHCP (STA + AP)

Races the real server with our own Offer/Ack (STA mode) or is the DHCP server for clients on our SoftAP (AP mode). Gateway + DNS poisoning for chained MitM.

PHASE 2

Responder

LLMNR + NBT-NS name-poisoning plus SMB1 NTLMv2 Type-2 builder. Captured hashes logged to SD in hashcat mode-5600 format. Feed directly to the on-device cracker.

PHASE 2

WPAD NTLM harvest

Serves PAC file on port 80 + HTTP 407 Proxy-Authenticate challenge. Windows clients auto-fetch WPAD, auto-auth with current domain creds.

PHASE 2

On-device NTLMv2 cracker

Pure-C HMAC-MD5 wordlist runner. Reads hashcat-5600 lines from SD, tries each password. No PC needed. Seeds a starter wordlist on first run.

PHASE 2

Custom UX

Own renderer β€” list / grid / carousel views, RaspyJack-faithful info pages, screensaver, 7-sprite pirate icon pack baked from PNG via tools/sprite_sheet_to_icons.py.

UX

Every file in src/features/saltyjack/ opens with an attribution header crediting @7h30th3r0n3. Authorized testing only β€” hunt your own LAN.

WhisperPair β€” CVE probe for hundreds of millions of devices

Press W in the BLE menu. Scans for Google Fast Pair accessories β€” Sony XM5, Pixel Buds Pro, Jabra, JBL, Marshall, Nothing, OnePlus, Soundcore, Logitech β€” and probes each one for CVE-2025-36911. Vulnerable firmware responds to a Key-Based Pairing write even when it's not in pairing mode, silently letting an attacker take over the device in about ten seconds.

β˜… CREDIT Β· COSIC @ KU LEUVEN

The researchers who disclosed it

CVE-2025-36911 was disclosed by Preneel, Singelée, Antonijević, Duttagupta, and Wyns at COSIC, KU Leuven in January 2026. $15K Google bounty. POSEIDON's probe is a demonstration + self-check tool built on top of their published findings — stand on giants' shoulders, always.

β˜… Disclosure writeup whisperpair.eu β†’

What the probe does

Scan + classify

Active scan for Fast Pair service UUID 0xFE2C. Classifies each hit as pairable (spec-compliant) or in-use (shouldn't accept pairing β€” the vulnerable column). Model-ID lookup names the device on-screen.

STAGE 1

Real crypto probe

secp256r1 ephemeral keypair via mbedTLS (hardware accelerated on ESP32-S3). AES-128-ECB encrypts a valid Key-Based Pairing plaintext. 80-byte envelope lands on the target's KBP characteristic.

STAGE 2

Verdict + MAC lift

Response in 3 seconds = VULNERABLE. Silent drop = patched. When we have the accessory's anti-spoofing pubkey, we decrypt the response and extract the hidden BR/EDR MAC. Logged to /poseidon/whisperpair.csv.

STAGE 3

Probe-only. ESP32-S3 has no Classic Bluetooth radio so the full attack (bond + HFP mic capture + Find Hub registration) needs external hardware. Roadmap: nRF52 companion hat closes the loop. Authorized targets only β€” patches are rolling out unevenly, scan your own gear.

What's landing next

v0.6.0 shipped Argus mood sprite, six themes, ambient motion, the cooperative BLE refactor, the STA-mode raw-TX path, and the C5 protocol v3 with 5G scan terminator. v0.7 closes the BLE gap with a real nRF52840 companion dongle. Everything below is planned, not promised.

nRF52840 companion β€” real BLE 5.0

USB-CDC nRF52840 dongle for full BLE 5.0 sniffing, LE Secure Connection attacks, Coded PHY S=8 long-range, and direction finding. The S3 can scan and spam BLE but can't MITM a real pairing β€” nRF52 closes that gap. The four nRF52 features (scan, scout-strike, MITM relay, WiFi+BLE combo) shipped in v0.6.0 against a Feather hat; v0.7 hardens the path with a dedicated dongle.

v0.7 Β· HEADLINE

On-device WPA2 cracker

Dual-core PBKDF2-SHA1 runner that eats .22000 files straight from SD. Seeded wordlist, custom dictionary support, resume-from-last-line. No PC tether. Listed here because testers keep asking and we have the hashcat-format captures already.

v0.7 Β· CRACK

Sub-GHz on Hydra hat (arriving tomorrow)

Hydra RF hat lands on the bench tomorrow β€” any sub-GHz bugs surfaced during v0.6 testing get fixed the moment the hardware is here. CC1101 RF / nRF24 mousejack / sub-GHz replay / Pocket SDR all queued for the regression sweep.

v0.6.1 Β· SUB-GHZ

Thread / Matter enumeration (via TRIDENT)

TRIDENT's 802.15.4 radio already sniffs Zigbee. Next step: passive Thread discovery, node enumeration, commissioning-invite detection, Matter bridge fingerprinting. Output to SD as structured JSON.

v0.7 Β· 802.15.4

MIMIR drop-box (aspirational)

Design sketch, not code. Future companion drop-box on a Banana Pi BPI-M4 Zero running hcxdumptool + WPA2 cracker + Bjorn-style action DAG. POSEIDON would act as the USB-C control client. No ETA, no implementation today.
