As if the state of security wasn't already a headache worldwide, we now may have one more reason to worry about: a hacker has made available the source code that could allow more people to wage the kinds of extraordinary large assaults that recently knocked security news site KrebsOnSecurity offline. Brian Krebs reports:The source code that powers the "Internet of Things" (IoT) botnet responsible for launching the historically large distributed denial-of-service (DDoS) attack against KrebsOnSecurity last month has been publicly released, virtually guaranteeing that the Internet will soon be flooded with attacks from many new botnets powered by insecure routers, IP cameras, digital video recorders and other easily hackable devices. The leak of the source code was announced Friday on the English-language hacking community Hackforums. The malware, dubbed "Mirai," spreads to vulnerable devices by continuously scanning the Internet for IoT systems protected by factory default or hard-coded usernames and passwords. Vulnerable devices are then seeded with malicious software that turns them into "bots," forcing them to report to a central control server that can be used as a staging ground for launching powerful DDoS attacks designed to knock Web sites offline. The Hackforums user who released the code, using the nickname "Anna-senpai," told forum members the source code was being released in response to increased scrutiny from the security industry.
