2. Background
Founder & CEO, Mobile Strategy Partners LLC
Help organizations optimize mobile commerce from both a business & tech perspective
Perform Risk Assessments as a part of my practice
Participated in many IT security reviews throughout my career in ecommerce, mobile commerce
3. Frozen in fear
Security consistently reported as the biggest barrier to mobile banking and mobile commerce usage
47% of non-adopters cite security;73% fear hackers can break into their phones (Tom Wills, Javelin, 12/08 )
Security considered during purchase, implementation
Fraud fears limit Mobile Commerce functionality in N. America
Few commerce apps with a real checkout process
Limited transactional capabilities in mobile banking
Mobile payments wheels still spinning (esp. P2P)
Attacks follow adoption: Africa was first, hackers will turn to us
Phishing seems the most common & effective attack
SIM, Mobile phone fraud also related (Absa 07)
4. Its not what we fear
Mobile Commerce is basically safe, however consumers are still afraid
Everyone generally learned lessons of ecommerce
128-bit SSL
Multifactor Authentication
Phone Disabling features
Phone viruses, network hacks rare so far
Mobile makes us MORE secure in many ways
Balance, Transaction alerts, visibility
5. the danger is the unknown
Untested defenses are weak defenses
Monitoring systems an afterthought
Mobile new to Information Security teams
Consumer education lacking
Unsophisticated users with smart phones
6. Social trickery
Phishing proven effective, likely to continue
Phishing often cross-channel
Fake call centers, targeted attacks, detailed research
URL not visible on mobile browsers, URL shorteners
SMS alerts perfect temptation for phishing
Shortcode registration limits spoofing, but possible
Linking from SMS to web encourages email to web
Social networking, mobile convergence amplifies risk
7. Limited Detection
Few organizations monitor for mobile attacks
Variety of fraud detection systems exist for ecommerce sites but not optimized for mobile
Some adaptable to mobile, mobile requires more(e.g. monitor SMS patterns, web services, mobile web)
Security companies yet to fully focus on mobile
Recession, limited adoption discourages investment in defensive systems
Attacks can happen even if adoption is low!
8. Unsophisticated Users
What happens when my Mom has a smartphone?!
Unsophisticated userstoday tend to have unsophisticated phones which provide significant protection
Smartphone trend means most phones will be smart
My Mother-in-law & Father-in-Law have Blackberries
They are more vulnerable via phone thanAOL dial-up
Damage to unsophisticated users can create major perception problems for the entire industry
9. Recommendations
Continue discouraging SMS, email links to apps
Promote, encourage PIN-locking phones
Require Multifactor Authentication & dont bypass it
Avoid storing sensitive data on phones
Architect mobile systems with security in mind
Keep sensitive data out of DMZs
Continual penetration testing
Mobile-aware fraud detection
