What is camera-hack CLAUDE.md?

Security-research project instructions for studying Yoosee/Gwelltimes SC-B21 network cameras and firmware. They document network services, video streams, hardware details, project folders, and known attack surfaces.

Use them to investigate RTSP video streams, ONVIF camera control, firmware and SD-card paths, serial bridges, and vulnerability reports.

They give a researcher a precise map of the camera's exposed interfaces and repository structure before testing or writing advisories.

Token cost

What it costs to keep this loaded

Counted locally with the o200k_base tokenizer, which is exact for GPT models; Claude uses its own tokenizer and its counts differ. Treat this as one consistent yardstick across the catalogue rather than a bill. Prices are per million input tokens.

Model	Per session	Once invoked
Fable 5	$0.00468	$0.00468
Opus 5	$0.00234	$0.00234
Sonnet 5	$0.00094	$0.00094
Haiku 4.5	$0.00047	$0.00047

Security

Grade B, and why

camera-hack CLAUDE.md scanned grade B with 1 finding against 26 rules in 11 categories — prompt injection, anti-refusal, data exfiltration, privilege escalation, supply chain, agent snooping, system-prompt leakage, SSRF and excessive agency — measured 3d ago.

A static scan of the body, not an audit. Every finding is printed with the line that produced it so you can judge whether it matters here. A mod is markdown that instructs an agent; that is exactly why what it instructs is worth reading.

Asks for rootmediumPrivilege escalation

A mod that escalates privileges can change anything on the machine, not only the project.

What it actually says

CLAUDE.md

Project

Security research on Yoosee/Gwelltimes IP cameras. Current target: SC-B21 dual-lens PTZ (firmware 38.02.103).

Attack Surface

Port	Service	Auth	Notes
554/tcp	RTSP	Partial	`/onvif1` needs auth, `/cam/realmonitor` open
5000/tcp	ONVIF	None	Full enumeration, PTZ control, DoS via write ops

Ports only respond to SYN scans (sudo nmap -sS), not TCP connect.

RTSP Streams

Path	Resolution	Auth
`/onvif1`	1920x2160 H.265 15fps	Required
`/onvif2`	640x720 H.265 15fps	Required
`/cam/realmonitor`	Varies	None

Hardware

OEM: Shenzhen Gwelltimes Technology
Firmware: 38.02.103, Hardware Ver 2.1
Video: Dual lens stitched vertically (1920x2160 + 640x720)
WiFi: RTL8188 variant
Audio: G.711 PCM 16kHz mono
MAC OUI: 4C:B0:08 (Gwelltimes), A8:B5:8E (Bilian/WiFi)

Notes

ONVIF write operations (CreateUsers, SetHostname) crash the IPC process permanently
Camera requires power cycle to recover from DoS
Scripts have placeholder IPs — copy config.example to config.env

Changes

What this file has done since we first saw it

Hashed on every crawl. A supply-chain change to an agent config is a question of when, not whether, so the history is kept rather than the latest state alone.
