Botnets of Things

The relentless push to add connectivity to home gadgets is creating dangerous side effects that figure to get even worse.

Botnets have existed for at least a decade. As early as 2000, hackers were breaking into computers over the Internet and controlling them en masse from centralized systems. Among other things, the hackers used the combined computing power of these botnets to launch distributed denial-of-service attacks, which flood websites with traffic to take them down.

But now the problem is getting worse, thanks to a flood of cheap webcams, digital video recorders, and other gadgets in the “Internet of things.” Because these devices typically have little or no security, hackers can take them over with little effort. And that makes it easier than ever to build huge botnets that take down much more than one site at a time…

Security vs. Surveillance

  • Don't Panic: Making Progress on the 'Going Dark' Debate
  • February 1, 2016

Both the “going dark” metaphor of FBI Director James Comey and the contrasting “golden age of surveillance” metaphor of privacy law professor Peter Swire focus on the value of data to law enforcement. As framed in the media, encryption debates are about whether law enforcement should have surreptitious access to data, or whether companies should be allowed to provide strong encryption to their customers.

It’s a myopic framing that focuses only on one threat—criminals, including domestic terrorists—and the demands of law enforcement and national intelligence. This obscures the most important aspects of the encryption issue: the security it provides against a much wider variety of threats…

How an Overreaction to Terrorism Can Hurt Cybersecurity

Many technological security failures of today can be traced to failures of encryption. In 2014 and 2015, unnamed hackers—probably the Chinese government—stole 21.5 million personal files of U.S. government employees and others. They wouldn’t have obtained this data if it had been encrypted.

Many large-scale criminal data thefts were made either easier or more damaging because data wasn’t encrypted: Target, T.J. Maxx, Heartland Payment Systems, and so on. Many countries are eavesdropping on the unencrypted communications of their own citizens, looking for dissidents and other voices they want to silence…

Antivirus Companies Should Be More Open About Their Government Malware Discoveries

Antivirus companies had tracked the sophisticated—and likely U.S.-backed—Regin malware for years. But they kept what they learned to themselves.

Last week we learned about a striking piece of malware called Regin that has been infecting computer networks worldwide since 2008. It’s more sophisticated than any known criminal malware, and everyone believes a government is behind it. No country has taken credit for Regin, but there’s substantial evidence that it was built and operated by the United States.

This isn’t the first government malware discovered. GhostNet is believed to be Chinese. Red October and Turla are believed to be Russian. The Mask is probably Spanish. Stuxnet and Flame…

Danger Lurks in Growing New Internet Nationalism

Cyber-espionage is old news. What's new is the rhetoric, which is reaching a fever pitch right now.

For technology that was supposed to ignore borders, bring the world closer together, and sidestep the influence of national governments, the Internet is fostering an awful lot of nationalism right now. We’ve started to see increased concern about the country of origin of IT products and services; U.S. companies are worried about hardware from China; European companies are worried about cloud services in the U.S; no one is sure whether to trust hardware and software from Israel; Russia and China might each be building their own operating systems out of concern about using foreign ones…
