Hacker Summer Camp: Security Cons Blossom In The Desert

The mercury is expected to top 104 degrees Fahrenheit (40 C) in Las Vegas next week. And that could mean only one thing: it’s conference time for some of the world’s top computer hackers.   Indeed, next week brings the 22nd installment of the DEFCON hacker conference in Las Vegas, and the 18th of Black Hat, DEFCON’s younger, more straight-lace sibling. But, while Black Hat and DEFCON are still the main attraction on the Las Vegas strip, they’re hardly the only shows in town. B-Sides Las Vegas, an alternative mini-con, is in its fifth year and is attracting many of the “cool kids” in the security community to do presentations and demos on Tuesday and Wednesday, August 5 and 6th over at the Tuscan Suites and Casino. Running alongside B-Sides is Passwords 14, a conference that started in Norway and is in its second year on U.S. soil. As its name would […]

This Week In Security: Poking Holes In Two Factor Authentication

It was another busy week in the security world. There was big news on the legal front, as The U.S. Supreme Court took steps to protect the data stored on mobile devices from warrantless searches by police. (That’s good news.) But the week also plenty of concerning stories about the security of data stored on mobile phones, tablets and the like. One of the stories that gained a lot of attention was DUO Security’s report on a flaw in PayPal’s two factor authentication feature that could expose the accounts of  security-conscious PayPal users. As The Security Ledger reported, DUO researcher Zach Lanier discovered a flaw in mobile APIs published by PayPal that would allow anyone with a valid PayPal user name and password to sidestep two-factor authentication when accessing PayPal accounts that had that option enabled. After DUO went public with information on the flaw, PayPal disabled two factor authentication […]

Paypal Disables Two Factor From Mobile

In the wake of a disclosure, yesterday, that a secure log-in feature was vulnerable to hacking, PayPal has suspended the ability of customers who elect to use the feature to log in to PayPal using the company’s mobile application. In a blog post on Wednesday, PayPal Director of Global Initiatives Anuj Nayar said that the company took the step of disabling mobile application log ins after the researcher, Zach Lanier of DUO Security, published his findings in a blog post yesterday. As reported by The Security Ledger, researcher Zach Lanier of DUO Labs discovered that a PayPal mobile API (application program interface) for its Security Key two-factor authentication technology contains a vulnerability that would allow even a non-technical hacker to bypass the second factor when accessing a Paypal customer’s account. The problem comes up when trying to access a Paypal account protected using two-factor authentication using a PayPal mobile application – […]

Researchers Sidestep Paypal Two-Factor Authentication

Researchers at DUO Security claim to have found a way of bypassing a two factor authentication feature that secures logins to Paypal.com, eBay’s online payment service. The vulnerability could allow an attacker who has stolen a Paypal customer’s user name and password to gain access to the account, even though the customer had enabled the more secure two-factor authentication option. DUO described the problem in a blog post early Wednesday. According to researcher Zach Lanier, Paypal has published an API (application program interface) for its Security Key two-factor authentication technology that contains a vulnerability that would allow even a non-technical hacker to bypass the second factor when accessing a Paypal customer’s account. An attacker only needs a victim’s PayPal username and password in order to access a two-factor protected account and send money. “The protection offered by the two-factor Security Key mechanism can be bypassed and essentially nullified,” the company wrote in […]

This Week In Security: Ebay’s School of Hard Knocks

It’s the end of another busy week in the security world. As we’re wont to do at The Security Ledger, we had DUO Security Evangelist Mark Stanislav in to the deluxe Security Ledger Studios to talk about the events of the week. On the agenda this week: the continued fallout from the hack of online auction giant eBay. The company ran into a thicket of criticism this week for the breach and its botched response. Despite knowing about the security breach for weeks, eBay seemed unprepared for the fallout once the news became public. Beyond its statements to the press, the company hadn’t taken steps to streamline the (inevitable) flood of customers who wanted to update their password. In fact, more than a day after the news broke, eBay still hadn’t made mention of it on their home page. What lessons can we learn from the breach at online auction […]
