Cupid Fires Arrow at OpenSSL's Heart
Jun 10, 2014 7:26 AM PT
As if the discovery of the Heartbleed flaw weren't enough woe for OpenSSL, more than half a dozen additional defects have been discovered in the code used to protect communication on the Web.
Among them is one dubbed "Cupid" by its discoverers. The flaw can be used to compromise enterprise networks.
Like Heartbleed, Cupid uses a malicious heartbeat packet to compromise a TLS connection. TLS, or Transport Layer Security, is used to secure communications on the Internet.
However, in Cupid's case, that TLS connection is being made over EAP, which is used to establish a WiFi connection. EAP, or Extensible Authentication Protocol, is an authentication framework used on WiFi networks and for point-to-point connections such as virtual private networks, or VPNs.
"Cupid is heartbleed in different clothing," Kevin Bocek, vice president of product marketing at Venafi, told TechNewsWorld.
Because Cupid can be used to attack VPN connections, it can be very dangerous to the enterprise, according to Bocek.
"What's most scary to me is that it gives an attacker access to information at the corporate gateway," he said. "It could potentially retrieve very valuable information, including the keys and certificates used to say any given VPN source is trusted, and user names and passwords."
The discovery of Cupid came during a week whem the OpenSSL team announced seven vulnerabilities covering four versions of OpenSSL: 0.9.8, 1.0.0, 1.0.1 and 1.0.2.
The most serious of the vulnerabilities allows a man-in-the-middle attack to be mounted on a system.
"This vulnerability allows malicious intermediate nodes to intercept encrypted data and decrypt them while forcing SSL clients to use weak keys which are exposed to the malicious nodes," according to Lepidum, the company that brought the flaw to the attention of the OpenSSL team.
While new vulnerabilities continue to be discovered in OpenSSL, old flaws won't be fading away soon, Bocek warned. "We haven't heard the last of Heartbleed. Cupid is an example of that."
Mobile advertising can be not only annoying, but also dangerous. Ad networks can be used to infect mobile phones with malware, as well as siphon sensitive information from the devices.
"Some of the most significant risk factors affecting corporate employees and individual mobile users, such as data loss and PII collection, occur not by the application itself, but within mobile advertising libraries and other library components such as social media or analytic tools," Ryan W. Smith of Mojave Networks, recently wrote in a company blog.
Mojave released these findings, based on its recent research:
- Sixty-five percent of applications connect to an ad network where it's almost impossible for users to decipher which ad network is tapping into their applications and data.
- Each application alone typically has nine permission requests, and on average, five of those permissions are considered dangerous.
- At least 78 percent of all applications downloaded by business users connect either to an ad network or to a social media or analytics API.
Not Just a Consumer Issue
Those numbers should raise concerns in the enterprise. They suggest that corporate data could be at risk on phones used both for business and personal use by employees.
Although the issue of apps scraping more data from a user's phone than they need is usually framed as a consumer issue, it can spill over into the corporate world, acknowledged Elias Manousos, founder and CEO of RiskIQ and cochair of tohe Anti-Malvertising Work Group.
"These ad networks are using behavioral targeting to track consumers whether they're working at a company or using their phone for personal use. They're not differentiating between the two," Manousos told TechNewsWorld.
"If you're storing corporate information on the phone, and a company is not using its own containers to lock down that information and it's made available to the apps on the device, then advertising could become a problem for your company," he added.
Security pros should ensure that corporate information sent to employees' phones be protected from access by applications on a device either through encryption or segregation, recommended Manousos.
Ransomware has begun to appear in the mobile realm, but it's been relatively unsophisticated. Recently, however, there have been signs that extortionists are ready to take their game up a notch.
Researchers at Eset have discovered a malware strain for Android phones that they're calling "Simplocker." The bad app will search for an SD card on a phone and encrypt all the data on the card. To get a key to decrypt the data, a user has to pay a ransom.
That technique is also used by Cryptolocker, a popular PC ransomware program. However, Simplocker uses a less sophisticated encryption scheme to do its nasty work.
At this point, the malware seems to be in the development stage. "We're not seeing any reports of it in the wild yet," Eset Security Researcher Lysa Myers told TechNewsWorld. "It's probably a proof of concept."
"They had a similar process when Cryptolocker first started," she added. "They had early attempts that were less sophisticated, and as they discovered it was something that was effective, they put more effort into it, making it robust."
