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 […]

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 […]

Code Spaces Probably A ‘Target of Opportunity’

The spectacular collapse this week of Code Spaces, a cloud-based code repository, may have been the result of a an unspectacular “opportunistic” hack, rather than a targeted operation, according to one cloud security expert. The sudden demise of the online application repository has sent shock waves through the tech industry, laying bare what some say are lax practices among many cloud-based application and infrastructure providers. But the attack itself was almost certainly the result of a larger, indiscriminate cyber criminal campaign, said Jeff Schilling, the Chief Security Officer of Firehost, a Texas-based secure cloud provider. “This is something we pretty frequently: companies get held ransom with a DDoS attack, and if that doesn’t work, (the attackers) will resort to doing other things,” Schilling told The Security Ledger. But Code Spaces almost certainly wasn’t the only company the extortionists worked on, Schilling said. Instead, the company was likely caught up in a wide net […]

IPMI Insecurity Affects 200k Systems

It has been almost a year since security researcher Dan Farmer first warned of the danger posed by Intelligent Platform Management Interface (IPMI) – a ubiquitous protocol used to do remote management of servers. According to a new report, however, that warning went unheeded. Writing last week (PDF), Farmer said that a world-wide scan for systems using the Intelligent Platform Management Interface (IPMI) protocol identified over 230,000 Baseboard Management Controllers (BMCs) exposed to the Internet. As many as 90% of the exposed systems could be compromised by exploiting what Farmer characterized as “basic configuration and protocol weaknesses.” Even more worrying, the 230,000 systems that are Internet accessible are probably just a fraction of all the vulnerable systems that might be attacked, with many deployed on (hackable) corporate and private networks. Farmer is reiterating calls for public and private sector organizations to wake up to the dangers posed by IPMI. Hackers who are able to compromise Baseboard Management […]

Heart Attack? Fixes For More Critical Holes In OpenSSL

Just a month after a critical security hole in OpenSSL dubbed “Heartbleed” captured headlines around the globe, The OpenSSL Foundation has issued an other critical software update fixing six more security holes, two of them critical. The Foundation issued its update on Thursday, saying that current versions of OpenSSL contain vulnerabilities that could be used to carry out “man in the middle” (or MITM) attacks against OpenSSL clients and servers. SSL VPN (virtual private network) products are believed to be especially vulnerable. Users of OpenSSL versions 0.9.8, 1.0.0 and 1.0.1 are all advised to update immediately. According to information released by the OpenSSL Foundation, an attacker using a carefully crafted handshake can force the use of “weak keying material in OpenSSL SSL/TLS clients and servers.” That could lay the groundwork for man-in-the-middle attacks in which an attacker positions herself between a vulnerable client and server, decrypting and modifying traffic as it passes through the attacker’s […]
