The Apple iPad Air 2 is without a doubt the best iPad the company has ever produced, and arguably the best tablet ever sold. Compared to iPad releases of past years, though, it's clear that fewer people will experience this new model. That's unfortunate, because the new iPad Air is a work of art. It's 18 percent thinner than the original iPad Air, clocking in at just 6.1 mm thick, which is quite noticeable. Coming with a 9.7-inch Retina display, it also weighs slightly less than the original Air (0.96 pounds, not especially noticeable) and has a slightly improved display (though it retains the same 2048 by 1536-pixel resolution and again, is probably not something you'll really notice unless you compare it side-by-side with an older model). The Air 2 has improved silicon -- a 40 percent faster processor and 2.5X faster graphics performance. That translates into snappier performance that you will notice early on, but which you'll soon take for granted. Other, more functional … [Read more...] about Apple’s new iPad Air 2: An amazing tablet that few people need

Some large security breaches that happened years ago are the gifts that keep on giving -- at least for hackers. GitHub, a code repository, warned on Thursday that hackers were trying to access "a large number of GitHub.com accounts" by using email addresses and passwords that the fraudsters had acquired from earlier security breaches. It's just the latest scam where hackers have sought to tap into previously released caches of data by hoping they hit upon some people who rely on the same password again and again. People who reuse their passwords are at higher risk of getting hacked because it can lead to a domino effect of infiltrated accounts. Even if you reuse passwords at sites that seem less sensitive than banking or financial services, that's still risky, given that hackers are often looking for personal information that can help them pull off other scams, such as taking out credit cards in your name. "People need to realize it's time to stop trying to memorize your password," … [Read more...] about Why sites are bugging you to reset your password
Email privacy used to be a big concern for Cal Tech professor Maria Spiropulu. "Whenever I was writing email, I was thinking that I was basically putting it as a headline in a newspaper," she told CBS News' Danielle Nottingham. But for two years, she's been testing an encrypted email service one of her students designed called ProtonMail, which promises to keep third parties and the government from snooping through your inbox. The recipient must enter a password to decode and read the message. ProtonMail co-founder Jason Stockman says the Edward Snowden NSA leaks inspired the idea. "Existing services you kind of trust them to keep your data secure and private but they keep the lock and key, but with ProtonMail you hold the lock and key," he said. The company is based in Switzerland, where strict privacy laws protect user data. Because the emails are encrypted from sender to recipient, not even ProtonMail can read what's stored on its server. "Even if we are compelled to hand over your … [Read more...] about CBS News Logo New encrypted email even the government can’t read
Conventional wisdom says that online security is built on several key ingredients, such as an overall awareness (like being savvy about phishing schemes), using strong passwords, and creating unique passwords that are never reused from one site or service to another. Since most people need to log in to dozens of different accounts, the uniqueness requirement virtually mandates a reliance on password managers -- programs like LastPass, Roboform, and Dashlane. These programs securely store all of your passwords in one place, and grant access to all of your sites and services with a single master password. But what happens if your master password is compromised? Then you haven't just suffered a potential breach for one account -- you've lost the keys to your digital kingdom. Such a nightmare scenario was brought to mind recently when popular password manager LastPass was hacked last week. In the wake of suspicious activity on its servers, LastPass said that email addresses, password … [Read more...] about How secure are password managers?
Florian Schaub is assistant professor of information and assistant professor of electrical engineering and computer science at the University of Michigan. Would you rather unlock your smartphone with a plain four-digit PIN or with a smiley-face emoji? Smartphone users commonly use emojis to express moods, emotions and nuances in emails and text messages -- and even communicate entire messages only with emojis. In 2015, a British company tried using emoji passcodes in place of PINs at bank ATMs. But there had been no formal study of how easy they were to use, or how secure they were in comparison to other methods, like PINs. To learn more, in the lab and in the real world, a team of researchers from the Technical University Berlin, Ulm University and University of Michigan, led by TU Berlin Ph.D. candidate Lydia Kraus, developed EmojiAuth, an emoji-based login system for Android smartphones. How well would users remember their emoji passcodes? Could they be more secure, … [Read more...] about CBS News Logo Why emojis might be your next password
