Vom Garagenprojekt zum Milliardengeschäft der Aufstieg von Open Source
Linux begann 1991 als unfertiger Kernel für wenige Rechner. Heute trägt Open Source Rechenzentren, Clouds, Behördenportale und KI-Plattformen. Der offene Code allein erklärt diesen Erfolg jedoch nicht. Entscheidend waren professionelle Betriebsmodelle, verlässlicher Support und die Erkenntnis, dass technologische Wahlfreiheit einen messbaren strategischen Wert besitzt. Für CIOs lautet die Kernfrage deshalb nicht mehr, ob Open Source……

TIKTOUK WordPress Toolkit Could Enable AWS, SMTP and API Credential Theft Attacks
A credential-collection toolkit dubbed TIKTOUK that combines WordPress reconnaissance, exposed-file harvesting, plugin credential decryption, and JavaScript secret scanning. The toolkit consists of two Python scripts, wp2s_poll.py and wp2s_crack.py, alongside a stripped Go-based Linux crawler named jscrawl-amd64. All three components retrieve targets from a central HTTP hub, execute assigned collection tasks, and submit status reports and…
