💡
Nature of the Hack:
Attackers used UI Spoofing against Bybit's Safe {Wallet} multisig system. When Bybit personnel signed off on a routine transfer from cold to hot wallet, the signature was intercepted and redirected to a malicious smart contract, granting the attacker full control of the wallet.

📐 Hack Timeline

⏰ 2:23 PM UTC (9:23 PM ICT)
Hackers test withdrawal with 90 USDT
⏰ 2:36 PM UTC (9:36 PM ICT)
Hackers drain 401,347 ETH + derivative tokens across 39 wallet addresses
🛡️ Why Bybit Needed Routine Transfers?
1. Provide Instant Liquidity
Hot wallets (internet-connected) process user withdrawal requests. When depleted, exchanges must refill from cold storage to ensure seamless withdrawals.
2. Risk Segregation Principle
Over 90% of assets are stored in offline multisig cold wallets. Only a small portion is periodically transferred to hot wallets to balance security and liquidity.
3. Reconciliation & Balance Monitoring
The system automatically triggers transfer requests when a specific coin's hot wallet balance drops below the minimum safety threshold.
4. Vulnerability Exploited
Because these transfers were routine, personnel developed a sense of familiarity. Hackers identified the schedule and executed the UI spoofing attack at the perfect moment.
⚠️
Attack Technique: Hackers used UI Spoofing to deceive Bybit staff. The screen displayed a legitimate internal transfer, but in reality, the signature approved a smart contract upgrade granting full control to the attackers.

🔹 3. The Combination Mechanism: Technical Correction + Black Swan
⚡
Definition of "One-Two Punch":
This is the perfect convergence of two negative factors, creating a multiplier effect that turns an ordinary correction into a deep crash.
This is the perfect convergence of two negative factors, creating a multiplier effect that turns an ordinary correction into a deep crash.
🥊 Punch 1: Market Regime Shift to Correction
📊 Technical Factors
- Bitcoin had become overheated
- RSI, MACD showed overbought conditions
- "Whales" began taking profits
- Natural selling pressure increased
🧠 Market State
- Last buyers had already entered
- Sellers were waiting on the sidelines
- Market was like a "taut string"
- Ready to snap at any moment
🦢 Punch 2: Black Swan Event
💥 Bybit Hack
- Unprecedented, unexpected event
- Largest theft in history (~$1.5B)
- Triggered panic, loss of trust in CEXs
- Massive withdrawals from exchanges
📉 Psychological Impact
- Fear & Greed Index dropped from 80 to 20-25
- Retail investors panic-selling
- Other exchanges temporarily paused withdrawals
- Domino effect spread across the market
⚡ When Two Punches Combine: The Domino Effect
🔺 BTC Price $98,424 (Peak)

📊 Domino effect diagram from the combination of both factors
🧠 Interaction Between the Two Factors
📉 From Market Correction
- ✅ Investors were already in "ready to sell" mode
- ✅ Trading volume was lower (fewer buyers)
- ✅ Volatility was already elevated
- ✅ Technical support levels were weaker
💥 From Bybit Hack
- 🔥 Triggered immediate panic-selling
- 🔥 Number of sellers surged suddenly
- 🔥 Volatility exploded, liquidity was sucked out
- 🔥 Support levels were broken one after another
🎯
Key Conclusion:
Neither the hack alone nor the technical correction alone caused the crash. It was the combination of both that created a "Double Negative" multiplier effect, making the correction deeper and more prolonged than usual.

🔹 4. Key Lessons from the Event
🔔 Lesson 1
Always Respect Technical Signals
The market provided advance warning. Early Warning Systems like PeakDip hold tremendous value.
🛡️ Lesson 2
Risk Management is Paramount
No one knows when a black swan will strike. Always have a risk mitigation plan and position management strategy.
💰 Lesson 3
Keep Cash During Turmoil
In periods of high volatility, cash is king. Buying opportunities will emerge when prices drop significantly.
🔒 Lesson 4
Self-Custody is Essential
"Not your keys, not your coins" was proven once again. Personal cold wallets are the safest solution.
🔹 5. Comparison with Similar Historical Events
| Event | Date | Loss | Similarity | Difference |
|---|---|---|---|---|
| Mt. Gox | 2014 | ~$460M | Major exchange hacked, loss of trust | Smaller market, no EWS signal existed |
| Bitfinex | 2016 | ~$72M | Hot wallet compromise | Much smaller scale |
| FTX Collapse | 2022 | ~$8B | Loss of trust in CEXs | Internal fraud, not a technical hack |
| Bybit Hack | 2025 | ~$1.5B | CEX hacked, mass panic | Coincided with 98% PEAK signal |
🔹 6. Conclusion
📌
One-Sentence Summary:
The Bybit hack on February 21, 2025, was a classic black swan event, but its impact was amplified by the market being in a technical correction phase – which was pre-warned by the Bitcoin PeakDip system with 98% confidence.
