How I Got Hacked: A Personal Story
I still remember the day I fell victim to a malicious MetaMask extension. I was browsing a popular cryptocurrency forum when I stumbled upon a “limited-time offer” to increase my Ethereum balance by 10x. The extension seemed legitimate, with a convincing logo and dozens of positive reviews. I installed it, and within minutes, my account was drained.
The Red Flags I Missed
Upon reflection, I realized I had ignored several red flags:
- Suspicious reviews: The reviews were overly positive and lacked specific details.
- Lack of transparency: The extension’s developers didn’t provide clear information about their team or company history.
