Echidna is a weird creature that eats bugs and is highly electrosensitive (with apologies to Jacob Stanley) More seriously, Echidna is a Haskell program designed for fuzzing/property-based testing of Ethereum smarts contracts. It uses sophisticated grammar-based fuzzing campaigns based on a contract ABI to falsify user-defined predicates or Solidity assertions. We designed Echidna with modularity in mind, so it can be easily extended to include new mutations or test specific contracts in specific cases. Features Generates inputs tailored to your actual code Optional corpus collection, mutation and coverage guidance to find deeper bugs Optional Slither integration to extract useful information before the fuzzing campaign Curses-based retro UI, text-only or JSON output Automatic testcase minimization for quick triage Seamless integration into the development workflow Maximum gas usage reporting of the fuzzing campaign Support for a complex contract initialization with Etheno and Truffle Changelog v2.0.3 This release focuses on getting enhanced coverage during a fuzzing campaign when handling non-utf8 strings, extreme signed integers and the fallback function. It also improved the scripts to build Docker containers. Fixed Avoid resetting accounts if there is a deployed contract (#795) Fixed decoding non-utf8 strings from slither printer (#799) Fixed generation and mutation of extreme signed integers (#791) Removed fallback from signature map when it is not defined (#772) Refactored Docker scripts and tests (#706) [hide][Hidden Content]]

La plataforma de de criptotransacciones Crypto.com ha reconocido finalmente, con varios días de demora, que el pasado lunes 17 de enero sufrió un ataque informático que se saldó con el robo de 34 millones de dólares en criptodivisas. Los hackers se llevaron 4.836,26 ethereum por valor de 15,3 millones de dólares, 443,93 bitcoin por valor de 18,6 millones de dólares y aproximadamente 66.200 dólares en otras criptomonedas de alrededor de 483 carteras digitales. El ataque informático obligó a la plataforma a frenar cualquier tipo de retirada de fondos durante el lunes. El parón en el servicio se dilató durante 14 horas, una horquilla de tiempo que los usuarios tuvieron que utilizar para cambiar sus credenciales de acceso. Los usuarios no perderán su dinero y se aumentará la seguridad Los usuarios que se hayan visto afectados por el robo no perderán su dinero. La compañía ha emitido un comunicado en el que asegura que en la mayoría de los casos se evitó la retirada no autorizada mientras que en el resto de casos se reembolsó a los clientes la cantidad robada. Parece increíble que, tras el robo a Coinbase, haya podido completarse otro ciberataque de este tipo. Los piratas informáticos, además, no habrían tenido que rascarse demasiado la cabeza: pudieron ingresar a las cuentas sin la necesidad de autenticación de dos factores, aunque se desconoce cómo lo hicieron. Ante este ataque, además de cambiar contraseñas, también se ha tenido que renovar el programa de autenticación de dos factores de Crypto.com y se han revocado todos los tokens 2FA existentes. También se han contratado empresas externas de seguridad y se ha incluido un retraso de 24 horas para las transacciones. De esta manera, habrá un margen de tiempo para echar para atrás la transacción si se realiza de forma ilícita. De forma paralela, la plataforma de criptotransacciones ha anunciado que incorporará un programa de seguro llamado Programa mundial de protección de cuentas. Es similar al WAPP y permite reclamar hasta 250.000 dólares en caso de que las carteras digitales hayan sido pirateadas.
