Why Proving the Source of a Cyberattack is So Damn Difficult
President Barack Obama’s public accusation of Russia as the source of the hacks in the US presidential election and the leaking of sensitive emails through WikiLeaks and other sources has opened up a debate on what constitutes sufficient evidence to attribute an attack in cyberspace. The answer is both complicated and inherently tied up in political considerations.
The administration is balancing political considerations and the inherent secrecy of electronic espionage with the need to justify its actions to the public. These issues will continue to plague us as more international conflict plays out in cyberspace…
Hackers Are Putting U.S. Election at Risk
Russia has attacked the U.S. in cyberspace in an attempt to influence our national election, many experts have concluded. We need to take this national security threat seriously and both respond and defend, despite the partisan nature of this particular attack.
There is virtually no debate about that, either from the technical experts who analyzed the attack last month or the FBI which is analyzing it now. The hackers have already released DNC emails and voicemails, and promise more data dumps.
While their motivation remains unclear, they could continue to attack our election from now to November—and beyond…
Can You Trust IRS to Keep Your Tax Data Secure?
Monday is Tax Day. Many of us are thinking about our taxes. Are they too high or too low? What’s our money being spent on? Do we have a government worth paying for? I’m not here to answer any of those questions—I’m here to give you something else to think about. In addition to sending the IRS your money, you’re also sending them your data.
It’s a lot of highly personal financial data, so it’s sensitive and important information.
Is that data secure?
The short answer is “no.” Every year, the GAO—Government Accountability Office—reviews IRS security and issues a report. The title of …
Data Is a Toxic Asset, So Why Not Throw It Out?
Thefts of personal information aren’t unusual. Every week, thieves break into networks and steal data about people, often tens of millions at a time. Most of the time it’s information that’s needed to commit fraud, as happened in 2015 to Experian and the IRS.
Sometimes it’s stolen for purposes of embarrassment or coercion, as in the 2015 cases of Ashley Madison and the U.S. Office of Personnel Management. The latter exposed highly sensitive personal data that affects security of millions of government employees, probably to the Chinese. Always it’s personal information about us, information that we shared with the expectation that the recipients would keep it secret. And in every case, they did not…
When Hacking Could Enable Murder
Cyberthreats are changing. We’re worried about hackers crashing airplanes by hacking into computer networks. We’re worried about hackers remotely disabling cars. We’re worried about manipulated counts from electronic voting booths, remote murder through hacked medical devices and someone hacking an Internet thermostat to turn off the heat and freeze the pipes.
The traditional academic way of thinking about information security is as a triad: confidentiality, integrity and availability. For years, the security industry has been trying to prevent data theft. Stolen data is used for identity theft and other frauds. It can be embarrassing, as in the Ashley Madison breach. It can be damaging, as in the Sony data theft. It can even be a national security threat, as in the case of the Office of Personal Management data breach. These are all breaches of privacy and confidentiality…
The Risks—and Benefits—of Letting Algorithms Judge Us
China is considering a new “social credit” system, designed to rate everyone’s trustworthiness. Many fear that it will become a tool of social control—but in reality it has a lot in common with the algorithms and systems that score and classify us all every day.
Human judgment is being replaced by automatic algorithms, and that brings with it both enormous benefits and risks. The technology is enabling a new form of social control, sometimes deliberately and sometimes as a side effect. And as the Internet of Things ushers in an era of more sensors and more data—and more algorithms—we need to ensure that we reap the benefits while avoiding the harms…
Can Laws Keep Up with Tech World?
On Thursday, a Brazilian judge ordered the text messaging service WhatsApp shut down for 48 hours. It was a monumental action.
WhatsApp is the most popular app in Brazil, used by about 100 million people. The Brazilian telecoms hate the service because it entices people away from more expensive text messaging services, and they have been lobbying for months to convince the government that it’s unregulated and illegal. A judge finally agreed.
In Brazil’s case, WhatsApp was blocked for allegedly failing to respond to a court order. Another judge …
VW Scandal Could Just Be the Beginning
Portuguese translation by Ricardo R Hashimoto
For the past six years, Volkswagen has been cheating on the emissions testing for its diesel cars. The cars’ computers were able to detect when they were being tested, and temporarily alter how their engines worked so they looked much cleaner than they actually were. When they weren’t being tested, they belched out 40 times the pollutants. Their CEO has resigned, and the company will face an expensive recall, enormous fines and worse.
Cheating on regulatory testing has a long history in corporate America. It …
Is It OK to Shoot Down a Drone over Your Backyard?
Last month, a Kentucky man shot down a drone that was hovering near his backyard.
WDRB News reported that the camera drone’s owners soon showed up at the home of the shooter, William H. Merideth: “Four guys came over to confront me about it, and I happened to be armed, so that changed their minds,” Merideth said. “They asked me, ‘Are you the S-O-B that shot my drone?’ and I said, ‘Yes I am,’” he said. “I had my 40 mm Glock on me and they started toward me and I told them, ‘If you cross my sidewalk, there’s gonna be another shooting.’” Police charged Meredith with criminal mischief and wanton endangerment…
Should Some Secrets Be Exposed?
Recently, WikiLeaks began publishing over half a million previously secret cables and other documents from the Foreign Ministry of Saudi Arabia. It’s a huge trove, and already reporters are writing stories about the highly secretive government.
What Saudi Arabia is experiencing isn’t common but part of a growing trend.
Just last week, unknown hackers broke into the network of the cyber-weapons arms manufacturer Hacking Team and published 400 gigabytes of internal data, describing, among other things, its sale of Internet surveillance software to totalitarian regimes around the world…
