5 Innovations That Caused Security Gaps

Habits of Effective Hackers

Five Innovations That Created Security Risks

• One new domain each second• 196 million domain names• 47 million new sites last year

1. Rapid Growth

Source:Verisign

Rich site-to-browser interaction

Browser is the new operating system

Browser is active in the application, not simply a passive display tool

2. Dynamic Web Apps: AJAX

3. User-Generated Content

• Half of Top 100 sites based on UGC

• 500 million users on Facebook

• 100 million accounts on Twitter

• 2.5 billion photos uploaded each month to Facebook

• 30 million new ads per day on Craigslist

• 20% of the workforce works remotely

• 1 in 11 organizations had remote workers infected

• 46% of remote infections come from infected Web sites

4. Remote Employees

Smartphone and tablet computing blur the line between personal and business computing

Companies must reconsider policies for devices that are not owned by the company

5. New Devices

Habits Of Effective Hackers

1. Malicious Javascript

(Four Habits Of Effective Hackers)

• USAToday.com ad network compromised (idatrinity.com)

• Visitors served malicious javascript bundled with ad for Roxio Creator 2009

• Automatically directed users to Rogue AV Web site (antivirusquickscanv1.com) through malicious traffic distribution system (liveavantbrowser2.cn)

Malvertising

Exploited Site (1 of 4)

instead of:

hxxp://www.pbs.org/parents/ptframe/images/bground-leaderboard.jpg


hxxp://qxfcuc.info/f.cgi?jzo

The above URL serves exploits that target a variety of software vulnerabilities, including those in Acrobat Reader (CVE-2008-2992, CVE-2009-0927, and CVE-2007-5659), AOL Radio AmpX (CVE-2007-6250), AOL SuperBuddy (CVE-2006-5820) and Apple QuickTime (CVE-2007-0015).

The domain qxfcuc.info is part of a malware campaign that includes tens of similar websites hosted off of a handful of common IP addresses. Similar exploit code was served from most of these domains, although a handful (e.g., yyoqny.info) display a message that suggests the criminal behind this campaign is compromising systems to build a botnet he will likely later lease. Translated from Russian, that message tells prospective leasers to "Send a message to ICQ #559156803; stats available under ststst02."

4. Web Exploit Kits


Web Exploit Kit Overview

– Most exploits served by exploit kits – (ready-made tools sold/used by criminals to attack

vulnerable software components – Many exploit sites, but few exploit kit types

– a handful of kit types comprise the majority of exploit sites

– Examples • LuckySploit, Fragus, UniquePack, NucPack• Tornado, Fiesta, IcePack, FirePack, MPack

Barracuda Labs Technology:Exploit Kit Detector (EKD)

– Leverage the many-to-few relationship between exploit sites and exploit kit types

• Focus of the handful of kit types that correspond to the majority of exploit sites

– Use information invariant to these kits to detect instances of them in a site-independent fashion
