Holding Bitcoin is only the starting point for institutions. As BTC becomes collateral, liquidity, and settlement infrastructure, BTCFi depends on productive use within a verifiable security perimeter. @rootstock_io has spent over eight years building infrastructure for that shift. 🧵

From Duplicate to $2,500 on @Hacker0x01. 📉📈 My report was initially closed as a duplicate, but later reopened after review confirmed there wasn’t an existing report with sufficient details and a reproducible PoC. Thanks @RootstockLabs for the fair review!

🚨 Seeing a new round of emails claiming "a legal subpoena has been delivered to Google LLC". If you get the email for your account: relax, it’s phishing. Attackers are abusing Google Sites + DKIM to make it look real. Screenshots like the one below are making the rounds. Details: thehackernews.com/2025/04/ph…

Hackers can steal 2FA codes and private messages from Android phones! Researchers discovered a new Android side-channel that defeats app isolation. By installing a malicious app, an attacker can directly see what other apps display, for instance 2FA codes or Seed phrases! The exploit uses Android APIs and a hardware side channel present on nearly all modern devices. Google has declined to fix this, resolving the report as “Won’t fix (Infeasible).” If you show sensitive data on your screen, you risk losing all your crypto. Simply don't use your phone to secure your crypto. Use a hardware wallet!

¡Ok, como en Dragon Ball! Milei es Goku, liderando con fuerza. Caputo es Vegeta, estratega clave. Los problemas económicos, villanos como Frieza, llevaban 100 años causando caos. Tras 16 meses de lucha, los derrotaron, trayendo estabilidad. Argentina, como el planeta Tierra tras la batalla, ahora brilla con esperanza. Los próximos años serán épicos, con el país como ejemplo mundial, ¡bendecido por las fuerzas del cielo!
