“My wallet has been hacked!”
Last night, a friend in the group suddenly shouted frantically in TG, his tone full of despair. Everyone looked, and his Solana wallet had just been emptied, with assets worth thousands of dollars instantly disappearing, leaving only a string of lonely transaction records showing that the tokens had been transferred.
“Did you click on some strange link?”
“No, I just used the XX batch tool to operate a bit…”
The moment this sentence was spoken, the group fell silent for three seconds, then exploded:
“Did you input your private key???”
The friend was confused: “Isn't this tool very popular? Many people are using it.”
“Do you know how it handles your private key in the background?”
“Isn’t it said to be ‘local operation’?”
As a result, everyone checked and found that this tool secretly uploaded the private key to the server while executing the transaction! It’s like handing your house key to a stranger, it could be stolen at any time.
💀 Really, incidents like this happen every year in the crypto circle, and the lessons for newcomers are never remembered.
From fake airdrops, fake Dapps, to now 'batch tools' stealing private keys, the tactics have changed, but they still target newcomers.
From the earliest phishing sites disguised as Dapps, to 'free token airdrops' inducing authorization, and now to today's 'batch tools' stealing private keys, hackers' methods are getting more covert, yet the lessons for newcomers are never remembered.
How to prevent your wallet from being hacked?
🔍 1. Check network requests before using the tool!
Open Chrome 【Inspect -> Network -> Fetch/XHR】 and see if there are any https requests quietly uploading your private key during the transaction process.
🛠 2. Choose a real local signing tool
I recommend a dev tool that I’m using myself, CiaoTool, it really saves me a lot of time. Previously, every time I operated the wallet, I had to click one by one, especially for batch transfers and batch wallet creation; just copying and pasting the private key was a headache, and mistakes were easy to make. After using CiaoTool, I found that it could be so smooth.
Its greatest feature is that all operations are completed locally, and the private key is not uploaded or stored, which is really crucial. There are a bunch of tools on the market, especially those web batch tools, who knows if they will secretly upload your private key? CiaoTool directly signs locally, giving no hackers a chance, ensuring full security.
🔑 3. Use local encryption to store your private key (AES encryption)
When choosing tools, you should also select those with local encryption storage functionality, so your private key won't be exposed in plaintext. Even if your device is hacked, it can reduce the risk.
⚠ 4. Never casually input your private key on TG BOTs or web tools!
No matter how popular the tool is or how many people are using it, as long as it requires you to input your private key, you must be cautious!
Conclusion: The most important thing in the crypto circle is not to get rich quickly, but to survive!
This friend's story made me alert again: The freedom and risks of Web3 coexist; your asset security can only be your own responsibility.
If you want to improve on-chain operation efficiency, you don’t have to sacrifice security. Choosing truly decentralized and secure tools is the way to go further in the crypto circle!💪
