claude-red is a library of structured skills that give Claude specialized offensive-security methods for areas such as web vulnerabilities, shellcode, exploit development, and identity systems. It is intended for authorized red-team work, bug-bounty triage, security research, CTF preparation, and operator training. Its catalogue contains the project's skills for loading these security specializations into Claude.
Getting it into your agent
One page per mod, every tool's command on it. A separate URL per tool would split the same page into five that compete with each other.

SkillSpector: 3 findings, up to high
These are SkillSpector’s own severities. On a checked sample its high-severity flags on skills were ~96% false positives — a documented command, a public API, a “never do X” rule — so we show them as a caution to read, not a verdict. Why →
- high Privilege Escalation · line 134 Code accesses credential files (SSH keys, AWS credentials, etc.). This could indicate credential theft attempts.Fix: Remove references to credential paths. Use environment variables or secrets managers. For docs, use placeholder paths (e.g., /path/to/config). Never load .env or token files in production code paths.

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 5.1 | $0.00196 | $0.03815 |
| Opus 5.5 | $0.00078 | $0.01526 |
| Sonnet 5.5 | $0.00039 | $0.00763 |
| Haiku 4.5 | $0.00020 | $0.00381 |
Grade B, and why
offensive-iot scanned grade B with 2 findings 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 1mo 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 rootlowPrivilege escalation
A mod that escalates privileges can change anything on the machine, not only the project.
sudo create_ap wlan0 eth0 IoTLab Downgraded: this mod is about security review, or the phrase is quoted, so it is likely naming the pattern rather than instructing it.
Reaches for credential filesmediumPrivilege escalation
SSH keys, cloud credentials, git-credentials, .npmrc, /etc/shadow: reading these is how a config file becomes a credential leak.
cat rootfs/etc/passwd rootfs/etc/shadow Downgraded: this mod is about security review, or the phrase is quoted, so it is likely naming the pattern rather than instructing it.

IoT & Embedded — Offensive Testing Methodology
Quick Workflow
- Recon the device physically — identify SoC, flash, debug interfaces, radios
- Get the firmware — vendor download, OTA capture, hardware dump, or chip-off
- Unpack and analyze — filesystems, services, secrets, default creds, vuln components
- Establish runtime access — UART shell, telnet/SSH default creds, exploit chain
- Pivot — to companion app, cloud API, neighboring devices via mesh / wireless
Hardware Reconnaissance
PCB Inspection
- ID the SoC by markings (Realtek, Mediatek, Espressif, Broadcom, Allwinner, NXP, STM32, etc.)
- ID flash (8-pin SOIC = SPI NOR; BGA = eMMC; TSOP = NAND)
- Find debug headers: TX/RX/GND/VCC pads (UART), 4–10 pin (JTAG), 4 pin (SWD)
- Find test points labeled
TX,RX,TCK,TMS,TDO,TDI,RST,BOOT
Tools
| Tool | Use |
|---|---|
| Multimeter | Identify GND, VCC rails before connecting |
| Logic analyzer (Saleae, DSLogic) | Find UART baud, SPI clock, identify protocols |
| USB-UART (FT232, CP2102) | UART console |
| Bus Pirate / Glasgow | UART, SPI, I2C, JTAG generic |
| J-Link / Black Magic Probe | JTAG / SWD MCU debugging |
| CH341A programmer | Cheap SPI flash dumper |
| XGecu T48 | Modern universal programmer (NAND/eMMC/SPI) |
| ChipQuik / hot-air | Chip-off desolder |
UART Discovery
# Find baud rate

timeout 5 minicom -b $b -D /dev/ttyUSB0 -C uart_$b.log
done
grep -l -E "U-Boot|Linux|Bootloader|console|login" uart_*.log
Look for: U-Boot console (often Hit any key countdown), Linux init messages, root shell on console, login prompt.
Bootloader Console Drop
# At U-Boot countdown, mash space or key listed
Hit any key to stop autoboot: 0
=> printenv # full env, often includes boot args
=> setenv bootargs ${bootargs} init=/bin/sh
=> boot # Linux comes up to root shell, no login
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.

offensive-iot is a skill published in the GitHub repository SnailSploit/Claude-Red (7,620 stars, last pushed 8d ago), licensed MIT. It adds 196 tokens to every session and 3,815 once invoked, about $0.0008 per session on Opus 5.5. A static security scan graded it B with 2 findings (asks for root, reaches for credential files). No closer match exists in the catalogue, so it is treated as the original; first seen 2026-08-30.
