Yada yada yada • People have always talked about work to their friends • What has changed is the nature of how we interact • We talk about our lives on our blogs, on social networking sites such as Facebook and Twitter, and on message boards pertaining to the work we're doing • What was once intimate and ephemeral is now available to the whole world, indexed by Google, and archived for posterity • A good open-source intelligence gatherer can learn a lot about what a company is doing by monitoring its employees’ online activities Bruce Schneier Slide 9 © First Base Technologies 2012

- 14. Data loss • Unencrypted storage and backup • Poor or missing passwords and PINs • No automatic screen lock • Mobile apps often store sensitive data such as banking and payment system PIN numbers, credit card numbers, or online service passwords Slide 14 © First Base Technologies 2012
- 15. Network spoofing • Mobile devices use wireless communications exclusively and often public WiFi • SSL can fall victim to a downgrade attack if app allows degrading HTTPS to HTTP • SSL could also be compromised if app does not fail on invalid certificates, enabling MITM attacks Slide 15 © First Base Technologies 2012

- 17. UI impersonation • Malicious app creates UI that impersonates that of the phone’s native UI or the UI of a legitimate application • Victim is asked to authenticate and ends up sending their credentials to an attacker http://blogs.mcafee.com/mcafee-labs/android-malware-pairs-man-in-the-middle-with-remote-controlled-banking-trojan Slide 17 © First Base Technologies 2012
- 18. BYOD risks • Data loss: a stolen or lost phone with unprotected memory allows an attacker to access the data on it • Unintentional data disclosure: most apps have privacy settings but many users are unaware that data is being transmitted, let alone know of the existence of the settings to prevent this • Network spoofing attacks: an attacker deploys a rogue network access point and intercepts user’s data or conducts MITM attacks • Phishing: an attacker collects user credentials using fake apps or messages that seem genuine. • Spyware: the smartphone has spyware installed allowing an attacker to access or infer personal data • Surveillance: spying using open microphone and/or camera • Diallerware: an attacker steals money from the user by means of malware that makes hidden use of premium SMS services or numbers. • Financial malware: malware specifically designed for stealing credit card numbers, online banking credentials or subverting online banking or ecommerce transactions.
