Poor Patch Management Makes CMSes Low-Hanging Fruit for Hackers
Aug 13, 2013 2:58 PM PT
Content management systems like WordPress and Joombla have become popular targets for hackers in recent times because flaws in those systems can be leveraged for mischief across literally millions of websites.
WordPress is running on some 73 million websites and Joomla some 35 million, so if you're a cybercriminal with a fresh vulnerability to one of those CMS systems in your satchel, you can do some serious damage.
"For the most part, hackers are not compromising WordPress websites simply to deface them, but rather as the first step of a larger attack," Michael Sutton, vice president of security research at Zscaler, told TechnewsWorld.
"Compromised WordPress sites can serve as watering holes to serve up malware to unsuspecting users," he explained. "Servers hosting WordPress can be leveraged by hackers, utilizing extra resources to host botnets for DDoS attacks and spam."
Poor patch management is a primary contributor to compromising websites running popular CMS software. "When a new WordPress vulnerability is identified, the question is not 'are there any vulnerable sites?'" Sutton said. "The question is 'which sites are vulnerable?'"
Automation tools make it much easier for hackers to launch these attacks on any site running a CMS. Finding a vulnerability can sometimes be as simple as using a search engine to find websites broadcasting their out-of-date weaknesses to the Web.
"The No. 1 most important WordPress security advice is to make sure to keep your patches up to date," Sutton said.
"It is important not to use an obvious user name and password combination like 'admin' or 'password,' but that is a basic security principle for any website," he added.
"The bigger issue," continued Sutton, "is a lack of awareness -- awareness that these vulnerabilities exist, awareness that patches exist, and awareness that users need to take the time and effort to patch these vulnerabilities themselves."
BYOD's Transient Headache
With employees increasingly accessing their boss' networks with personal devices, security administrators can have difficulty keeping tabs on what's generating traffic on their nets. That gap in knowledge can pose major security risks to a company's data trove.
Even in environments with systems in place for monitoring mobile devices -- so called mobile device management systems -- transient mobile devices can pose a security threat.
One possible solution to that problem is to identify transient mobile devices by their activity on a network using a system such as the Passive Vulnerability Scanner offered by Tenable.
"If you ask any corporate IT administrator how many mobile devices they have on their network that are unmanaged, they're not going to know," Tenable CEO Ron Gula, a former NSA hand, told TechNewsWorld.
"What our PVS does," he continued, "is it looks at network traffic and identifies those mobile devices."
It does that through their user agent strings, their connections to online app stores, and certain network fingerprints they leave on the network.
"We can look at all the network traffic that goes in and out of an organization at the perimeter and identify them," Gula added. "It's the same thing as a network detection intrusion system, but instead of looking for intruders, you're looking for fingerprints of mobile applications and devices."
iPhone Fingerprint Scanner
Although it was discounted by several Internet sources last week, the rumor persists that the next iPhone will break ground in mobile authentication by embedding a fingerprint scanner in the handset.
While such a move could improve security on the mobile, it shouldn't be considered the last word on authentication, maintained Brendon Wilson, director of product management at Nok Nok Labs.
"It's an improvement because it combats a major source of security risk associated with passwords, namely password re-use," Wilson told TechNewsWorld.
"Users routinely re-use passwords across multiple sites," he explained, "which places them at increased risk when their password is compromised. Immediately, every account at other sites where they used that password is essentially compromised."
What must be realized is that Black Hats are nimble adversaries. A new form of identity protection will just be another challenge for them.
"Attackers will attempt to figure out how to steal fingerprints off surfaces, off devices, or how to have malware attack the underlying hardware to steal credentials," Wilson said.
"It would be a mistake to think fingerprint scanning is the final word in authentication," he added.
The killer app for authentication is one that "just works" across devices -- not only now, but as capabilities are added to those devices in the future.
"That's the one advantage passwords have right now," Wilson observed. "Everywhere you go, every device you use, there is some way to enter a password."

Bank of Scotland fined Pounds 750,000 by UK Information Commissioner's Office for faxing to members of the public mortgage claims and wills that should have been sent to the bank's document scanning department. On some 22 occasions from 2009 to 2012, bank employees misdialed fax numbers and sent confidential documents to individuals in the UK.
