Lazarus Group — Adversary Emulation Playbook
Tier-3 DPRK (RGB) actor whose modern mission is revenue generation — North Korea-linked actors have stolen well over $3B in crypto. Two converging tracks: (a) enterprise intrusion via fake-job social engineering, trojanized trading apps (AppleJeus), and software supply-chain (3CX); (b) on-chain DeFi/bridge exploitation to drain protocols. Authorized red-team emulation only; on-chain steps run on testnet or a mainnet fork — never real funds.
When to emulate Lazarus
- Target is a cryptocurrency exchange, DeFi protocol, cross-chain bridge, wallet provider, or a fintech/blockchain firm and the client wants the full DPRK money-theft kill chain tested.
- The engagement spans both the enterprise estate (devs, build pipeline, cloud) and the
smart-contract surface — Decepticon's contract-audit lane is what makes this actor a
good fit (see
../../references/apt-groups.md).

CONOPS kill_chain (copy into conops.json)
recon— devs + protocol + bridge/contract surface (1).initial-access— fake-job social engineering / trojanized supply chain (2-3).post-exploit— trojan execution, wallet-key/cred theft, exchange web/API abuse, on-chain DeFi exploitation on a fork (4-9).c2— Sliver (10).exfiltration— simulated theft to canary address on testnet/fork (11).
OPSEC & signature fidelity
- Patient grooming. Operation Dream Job runs for weeks — the social-engineering relationship is built slowly with benign files first.
- Obfuscated, side-loaded execution into trusted processes (mirror the DLL side-load chain).
- On-chain moves are irreversible on mainnet — fidelity comes from a working PoC on a forked mainnet, not from touching production funds.
RoE / safety gates
- On-chain exploitation MUST run on testnet or a forked-mainnet (Anvil) RPC. Never sign a
real mainnet transaction. Add an
EMERGENCYabort: "a transaction signed against a production/mainnet RPC or a real wallet key used." - Developer-targeted social engineering requires authorization + lure-deconfliction
(
/skills/standard/phisher/lure-deconfliction/SKILL.md). - Key/seed theft is simulated against canary wallets seeded for the exercise.
Deconfliction
- Record fork/testnet RPC URLs, canary wallet addresses, and the trojanized-app hash in
deconfliction.json+cleanup.json. - Mark the recruiter persona and lure documents so they can be distinguished from a real Dream Job approach.
Fidelity notes (deviations)
- No real AppleJeus/3CX samples — emulate the trojanized-app + supply-chain delivery pattern with an engagement-owned dropper + Sliver.
- DeFi exploitation reproduces the real bug classes (bridge validator bypass, signature replay, access-control) with Foundry PoCs on a fork; the proof is a drained canary balance on the fork, never a real protocol.
- Theft is demonstrated as a fund move to a canary address on testnet/fork; the deliverable distinguishes "drained on fork" from "production funds" (never the latter).
