🚨Jameson Lopp Issues Bitcoin Security Warning!
What’s happening?
Casa’s CSO Jameson Lopp warns of rising Bitcoin address poisoning—a scam using addresses with similar starting/ending digits to trick users into sending funds to attackers.
The scale:
48,000+ poisoned transactions spotted since July 2023
Surge resumed after Jan 2025, following a 2-month pause
$1.2M stolen in March 2025 via this method
$1.8M lost in Feb
Total Q1 2025 hack losses = $1.6B, with $1.4B from Bybit hack (largest in crypto history)
Who's behind it?
Cyber firms link these attacks to North Korean hacker group Lazarus, known for job scams, fake VC Zoom calls, and phishing schemes.
Lopp's Advice:
Double-check full BTC addresses before sending. Wallets must show full addresses to prevent deception.
