Searching for Binance in the Chrome Web Store will bring up a bunch of extensions like "Binance Market," "Binance Quick Login," or "Binance Helper." Binance does not have any official browser extensions. This article will expose these disguises. Download links: Binance website, mobile Binance official app, or check the iOS install guide if you don't have the App on iOS.
1. Why Binance Doesn't Have an Official Extension
Browser extensions have immense permissions to read and write all page DOMs, Cookies, and storage. For security reasons, Binance actively chooses not to release an extension. Any "official Binance extension" is an imposter.
2. Common Types of Fake Extensions
| Type | Surface Function | Real Threat |
|---|---|---|
| "Price Alerts" | Shows coin prices | Reads Cookies to steal login states |
| "Quick Login" | Password-free login | Hijacks passwords and 2FA |
| "Auto Trading" | Auto-orders on price triggers | Steals API keys |
| "Translation Assistant" | Translates pages | Injects malicious JavaScript |
| "Official Theme" | Binance-style UI tweaks | Replaces page content to hijack forms |
3. What Malicious Things Can Extensions Do?
1. Reading Cookies
Extensions can read the Cookies of all open pages. Binance's login state is stored in Cookies—once an extension grabs it, they have your login state.
2. Injecting JavaScript
Extensions can inject scripts into binance.com pages to alter:
- Withdrawal addresses (what you see is yours, but it's actually sent to the attacker)
- Displayed balances (hiding portions so you don't notice)
- Fake "login again" popups to steal your 2FA
3. Screenshots / Screen Recording
Extensions with certain permissions can take screenshots of your current tab, including the password entry interface.
4. Uploading Data
Extensions can access external URLs without restrictions, continuously sending your data to the attacker's server.
4. Identifying Malicious Extensions
Check Permissions
In the Chrome Web Store, click on the extension page → Details. Look at the permissions list:
- "Read and change all your data on all websites" — High risk
- "Read and modify clipboard" — Unnecessary
- "Manage your downloads" — Unjustified
Requesting these permissions for a simple "price display" is malicious behavior.
Check the Developer
Legitimate extension developers usually provide a company name and an email link. If you can't see developer info or the developer is anonymous — stay alert.
Check User Count and Reviews
"Binance" extensions with only hundreds or a few thousand users are almost always fakes. Pay close attention to one-star reviews to see if anyone reports "account stolen after installation."
5. Cleaning Up Installed Extensions
Chrome
Go to the address bar and type chrome://extensions → Find suspicious items → Remove. Restart Chrome.
Edge
Follow a similar process at edge://extensions.
Firefox
Go to about:addons → Extensions → Remove.
After cleaning them up, immediately:
- Change your Chrome / Microsoft / Firefox sync account password
- Change your Binance password + reset 2FA
- Check your Binance login history
- Delete your API keys
6. Official Related Extension Whitelist
The following extensions are useful and not Binance fakes, and are safe to install:
- MetaMask: Ethereum wallet, an independent project unrelated to Binance
- Phantom: Solana wallet
- uBlock Origin: Ad blocker
- Privacy Badger: Privacy protection
- HTTPS Everywhere: (Now integrated into browsers)
These genuinely improve security, but none of them are "official Binance extensions."
7. Long-Term Defense
1. Use Two Separate Browsers
- Financial Browser: Only used for Binance and banking bookmarks, absolutely no extensions installed.
- Daily Browser: Used for everyday extensions and web browsing.
Physical separation ensures extensions cannot touch financial accounts.
2. Use Browser Profiles
Chrome supports multiple Profiles. Create a dedicated Profile with zero extensions installed specifically for logging into Binance.
3. Regularly Audit Extensions
Clean up your extension list once a month. Delete the ones you don't use. Keep only the ones you frequently use and update regularly.
FAQ
Q1: What should I do if there's a "Binance" extension in the store claiming to be official? Click "Report Abuse," and Google will review it. However, the best approach is simply not to install it.
Q2: Will my account be stolen a few hours after installing a malicious extension? It depends on the extension's capabilities. Some instantly steal Cookies and transfer assets within minutes. Others lay dormant before acting. If you suspect anything, execute a full emergency response immediately.
Q3: Are there extensions on mobile browsers? Chrome mobile does not have an extension mechanism (making it safer). Firefox mobile has some extensions, but use them with caution.
Q4: Is there any "safe" Binance price display extension? There are no guarantees. It is recommended to use Binance APP notifications or the desktop client instead of extensions.
