Meet Marcus
Marcus is an active crypto trader on his Windows laptop. He frequently copies and pastes wallet addresses when sending tokens. One day, he downloads what claims to be a “Trading Bot” tool from a crypto forum. The tool supposedly automates small profitable trades. He installs it.What Happened
Step 1: The Malware Installation
The “Trading Bot” is actually a clipboard hijacker. Once installed, it runs silently in the background. The malware’s job: whenever Marcus copies a crypto wallet address to his clipboard, the malware replaces it with a different address (one controlled by the scammer).Step 2: The Swap
A few days later, Marcus wants to sell some tokens. He copies a recipient address (his own wallet on another exchange) to his clipboard. He’s about to paste it into a DEX interface to initiate the token swap. But before he pastes, he (fortunately) decides to visually verify the address is correct by checking it manually. He notices: the address he’s about to paste doesn’t match what he copied. His original address started with0x1A2B... but the clipboard now shows 0x9Z8Y...
He realizes his clipboard has been hijacked.
Step 3: The Investigation
Marcus runs an antivirus scan and discovers the “Trading Bot” malware. He removes it immediately, but realizes that if he hadn’t double-checked that address, he would have sent ₦500,000 to the scammer’s wallet instead of his own. Potential loss prevented: ₦500,000+Where the Scammer Almost Won
What Marcus Did Right (and Could Have Done Earlier)
He visually verified the address before sending. This saved him.
He could have prevented this by: Not installing untrusted software, running antivirus/antimalware regularly, typing critical addresses manually instead of copying and pasting, and using a hardware wallet (less vulnerable to clipboard malware).

Prevention
Never install software from untrusted sources.
Use antivirus/antimalware (Windows Defender is built-in; add Malwarebytes for extra scanning).
Verify addresses visually before sending funds (compare first and last 4 characters at minimum).
Type critical addresses manually or use QR codes from trusted sources.
Use a hardware wallet to minimize exposure to desktop malware.
