Brian Krebs is a popular reporter on the cybersecurity beat. He regularly exposes cybercriminals and their tactics, and consequently is regularly a target of their ire. Last month, he wrote about an online attack-for-hire service that resulted in the arrest of the two proprietors. In the aftermath, his site was taken down by a massive DDoS attack.In many ways, this is nothing new. Distributed denial-of-service attacks are a family of attacks that cause websites and other internet-connected systems to crash by overloading them with traffic. The "distributed" part means that other insecure computers on the internet—sometimes in the millions—are recruited to a botnet to unwittingly participate in the attack. The tactics are decades old; DDoS attacks are perpetrated by lone hackers trying to be annoying, criminals trying to extort money, and governments testing their tactics. There are defenses, and there are companies that offer DDoS mitigation services for hire. Basically, it's a size vs. size game. If the attackers can cobble together a fire hose of data bigger than the defender's capability to cope with, they win. If the defenders can increase their capability in the face of attack, they win. What was new about the Krebs attack was both the massive scale and the particular devices the attackers recruited. Instead of using traditional computers for their botnet, they used CCTV cameras, digital video recorders, home routers, and other embedded computers attached to the internet as part of the Internet of Things. Much has been written about how the IoT is wildly insecure. In fact, the software used to attack Krebs was simple and amateurish. What this attack demonstrates is that the economics of the IoT mean that it will remain insecure unless government steps in to fix the problem. This is a market failure that can't get fixed on its own.

The secretive British spy agency GCHQ has developed covert tools to seed the internet with false information, including the ability to manipulate the results of online polls, artificially inflate pageview counts on web sites, “amplif[y]” sanctioned messages on YouTube, and censor video content judged to be “extremist.” The capabilities, detailed in documents provided by NSA whistleblower Edward Snowden, even include an old standby for pre-adolescent prank callers everywhere: A way to connect two unsuspecting phone users together in a call.

he “tools” have been assigned boastful code names. They include invasive methods for online surveillance, as well as some of the very techniques that the U.S. and U.K. have harshly prosecuted young online activists for employing, including “distributed denial of service” attacks and “call bombing.” But they also describe previously unknown tactics for manipulating and distorting online political discourse and disseminating state propaganda, as well as the apparent ability to actively monitor Skype users in real-time—raising further questions about the extent of Microsoft’s cooperation with spy agencies or potential vulnerabilities in its Skype’s encryption. Here’s a list of how JTRIG describes its capabilities: • “Change outcome of online polls” (UNDERPASS) • “Mass delivery of email messaging to support an Information Operations campaign” (BADGER) and “mass delivery of SMS messages to support an Information Operations campaign” (WARPARTH) • “Disruption of video-based websites hosting extremist content through concerted target discovery and content removal.” (SILVERLORD)

• “Active skype capability. Provision of real time call records (SkypeOut and SkypetoSkype) and bidirectional instant messaging. Also contact lists.” (MINIATURE HERO) • “Find private photographs of targets on Facebook” (SPRING BISHOP) • “A tool that will permanently disable a target’s account on their computer” (ANGRY PIRATE) • “Ability to artificially increase traffic to a website” (GATEWAY) and “ability to inflate page views on websites” (SLIPSTREAM) • “Amplification of a given message, normally video, on popular multimedia websites (Youtube)” (GESTATOR) • “Targeted Denial Of Service against Web Servers” (PREDATORS FACE) and “Distributed denial of service using P2P. Built by ICTR, deployed by JTRIG” (ROLLING THUNDER)
