# Technique: Rug Pulls (Crypto Investment Fraud)
## Overview
A form of exit scam where developers of a cryptocurrency project (often a memecoin) suddenly liquidate all their holdings or drain the associated liquidity pool, causing the token's value to crash to zero immediately after hype and investment have driven the price up.
## Technical Details
- Type: Technique (Financial Fraud)
- Platform: Decentralized Finance (DeFi) Protocols, Liquidity Pools.
- Capabilities: Exploitation of smart contract functionality for rapid fund withdrawal.
- First Seen: Common within the last few years of the crypto market cycle.
## MITRE ATT&CK Mapping
- T1557 - Supply Chain Compromise (Indirectly, by compromising the integrity of the shared token/project)
- T1568 - Client Execution (Through the execution of the malicious smart contract function that drains funds).
## Functionality
### Core Capabilities
- Creating a token with perceived liquidity.
- Generating significant social media hype to attract retail investors ("pumping" the price).
- Removing liquidity or dumping developer-held tokens, causing the price collapse.
### Advanced Features
- Often masked by anonymous developer teams and high-yield promises.
## Indicators of Compromise
- File Hashes: N/A
- File Names: N/A
- Registry Keys: N/A
- Network Indicators: Large, immediate sell transactions originating from the contract deployer or main developer wallets.
- Behavioral Indicators: Lack of liquidity locks (liquidity not being locked for a specified period), "sell limits" being set too high or nonexistent, or unusually high rewards promised.
## Associated Threat Actors
- Anonymous developers associated with specific meme coin projects (e.g., Froggy Coin, Hawk Tuah Girl associated project).
## Detection Methods
- Signature-based detection: Analyzing smart contract code for functions allowing developers to instantly withdraw all pooled assets (e.g., lack of `transfer ownership` away from the deployer, or functions to remove all liquidity).
- Behavioral detection: Monitoring for dramatic and immediate price crashes following rapid initial growth.
