What Is a Dust Attack?
A dust attack is an attempt to de-anonymize your cryptocurrency address. Attackers send tiny amounts of crypto ("dust") to your wallet, hoping you’ll use these funds—revealing your transaction history and identity. While dust attacks don’t let hackers steal your coins directly, the exposed data can lead to:
- Personalized phishing scams
- Blackmail attempts
- Targeted social engineering
What Is Crypto Dust?
In blockchain terms, "dust" refers to trace amounts of coins/tokens—often leftovers from transactions. For example:
- Bitcoin (BTC): 500–1,000 satoshis (0.000005–0.00001 BTC)
- Ethereum (ETH): 0.0000001 ETH
Historically harmless, dust now fuels deanonymization attacks.
How Dust Attacks Work
Fraudsters send dust to thousands of wallets, then track these funds across exchanges/services to:
- Link addresses to a single owner.
- Identify wallets via IP leaks or KYC data.
- Launch targeted scams (e.g., "We know you own X BTC—pay us or we’ll expose you").

Dust vs. Phishing: Key Differences
| Dust Attack | Phishing Attack |
|-----------------|--------------------|
| Sends tiny crypto amounts | Includes malicious links |
| Tracks wallet activity | Tricks users into sharing keys |
| Passive data gathering | Active theft attempt |
Should You Worry About Dust?
No—if handled correctly:
✅ Ignore dust transactions—don’t spend or move them.
✅ Use coin control (e.g., Ledger Live) to isolate dust.
✅ Generate new addresses for each receipt.
✅ Convert dust to privacy coins (Monero) or cash via Bitcoin ATMs.

FAQs: Dust Attacks Explained
Q: How do scammers find my wallet address?
A: Blockchain transactions are public. Fraudsters scrape addresses from explorers or leaked databases—but they can’t see your identity unless you link wallets carelessly.
Q: Can dust attacks steal my crypto?
A: No. Dust itself is harmless, but interacting with it (e.g., spending) risks exposing your transaction graph.
Q: What’s the worst-case scenario?
A: Blackmail attempts ("We know you own X BTC")—which are empty threats if you ignore them.
Key Takeaways
- Dust attacks aim to break anonymity—not steal funds.
- Never spend dust—treat it like radioactive material.
- Bitcoin ATMs offer a clean exit by converting dust to cash.
Stay vigilant, and remember: Privacy is your best defense.
