Talk Abstract

This research documents the full operational stack of a modern crypto fraud operation: from phishing kit acquisition on Telegram markets through smart contract drainer deployment to MEV-based profit extraction.

Key Findings

Drainer-as-a-Service Ecosystem

The current market features at least 12 active DaaS providers offering:

Pre-audited drainer contracts with anti-analysis obfuscation
Phishing kit templates mimicking 40+ DeFi protocols
Affiliate panels with real-time drain tracking
Average fee: 20% of drained funds, auto-split on-chain

MEV Sandwich Taxonomy

We catalogued 847 unique MEV bots across Ethereum mainnet and identified three dominant sandwich strategies:

Tight sandwiches: target swaps in the same block, profit margin <0.1%
Wide sandwiches: span multiple blocks using validator collusion
Generalized frontrunning: simulation-based copy trades with gas escalation

Phishing Kit Analysis

Static analysis of 23 drainer kits recovered from Telegram reveals:

All implement eth_sign flow to bypass MetaMask’s eth_sendTransaction confirmation
18/23 include obfuscated permit signature harvesting for ERC-20 tokens
Average time from kit purchase to first victim: 4.2 hours
