„Running bitcoin at $80K. My 2010 prediction: $10M. So we're still early.”

4 data leaks reported today:
1. Coinbase's vendor Amplitude exposed some users’ contact data (funds unaffected).
2. Bithumb (Korea) had user data leaks.
In TradFi, two securities firms in Korea leaked data:
3. Mirae Asset
4. Daishin Securities
You can't prevent a leak, but you can protect yourself.
Leaked exchange data (names, emails, phone numbers, addresses, ID documents, transaction history) is mostly used for phishing, SIM swapping, and social engineering.
Reduce info you share
- Use a unique email alias for each exchange (SimpleLogin, Apple Hide My Email, etc). A leak then can't be linked to your other accounts, and you can spot which service leaked.
- Share only what's required. Don't add optional profile details.
- Use a dedicated phone number (a VoIP or secondary SIM) for exchange accounts if you can, since leaked numbers are the main route to SIM swaps.
Lock down the account
- Use a unique, long password from a password manager.
- Turn on hardware security keys (YubiKey) or passkeys, or at least an authenticator app.
- Avoid SMS 2FA.
- Enable withdrawal address whitelisting and a withdrawal time lock if the exchange offers them.
- Set up an anti-phishing code, which puts a code you choose in every legitimate email from the exchange.
- Review active sessions and API keys regularly. Delete any API keys you don't use.
- Restrict API keys to withdraw-disabled and IP-whitelisted.
Defend against
- SIM swapping: Ask your carrier to add a port-out PIN or number lock.
- Phishing and impersonation: Assume anyone who contacts you about your account, "security issues," or "refund recovery" is a scammer, even if they know your name, balance, or recent trades.
- Exchange support staff don't ask for your password, 2FA codes, or seed phrase.
- Never click links in emails or texts. Go to the site yourself.
- "Wrench attacks": Leaked addresses plus holdings data have led to real-world extortion and robberies. Don't publicize your holdings, and keep large balances out of anything tied to your home address if you can.
If a breach is announced
1. Change the exchange password and any other account that reused it.
2. Check haveibeenpwned.com for your email address.
3. Revoke API keys and active sessions.
4. Review recent withdrawals and security settings.
5. Watch for phishing emails and texts that reference the breach, because scammers move fast after one.
Stay SAFU! 🙏

THE BLOCK: Solflare said its staking provider has experienced a security breach, affecting the keys they hold for the Solflare validator. The Solana self-custody wallet platform said its validator has stopped producing rewards.
Solflare said users' SOL holdings are safe and that it will move to a new validator. Users do not need to take action as of now, but will need to migrate upon an app upgrade.

When BNB started 9 years ago, I never thought I would be ringing the bell for a blockchain token (treasury) on NASDAQ one day. I don’t know what shows crypto and tradfi converging more than this.

⚠️ Electrum users should update immediately!
ELECTRUM BITCOIN WALLET CONFIRMS CRITICAL SECURITY VULNERABILITY EXPLOITED IN THE WILD
Electrum has disclosed a high-severity vulnerability allowing malicious servers to trick users into sending Bitcoin to an attacker when increasing a transaction fee.
The attack works by intercepting a broadcast transaction and replacing it in the wallet’s history with a fake transaction redirecting funds to an attacker-controlled address.
If the user attempts to increase the fee using Replace-by-Fee (RBF), Electrum can sign the malicious transaction, sending the Bitcoin to the attacker.
Electrum confirmed two reported incidents, including one user who lost funds. Attackers even generated addresses matching the last four characters of the intended recipient’s address.
The vulnerability affects versions before 4.8.3 and has been patched in the latest release.
Users are urged to update immediately and verify all destination addresses and amounts before signing transactions.
