Social engineering (hacking)
"...social engineering was extremely effective in reaching my goals without resorting to using a technical exploit. I would look for the weakest link in the chain that was the least risk and cost to me [...] if an attacker can walk into the server room without much chance of detection, that's all she wrote"
Kevin Mitnick (arrested in 1995)
Social engineering today
1. Retrieved username and password database through known vulnerability in CMS2. CEO and COO had very short passwords and were recovered3. CEO and COO used same credentials for other services (Twitter, email, LinkedIn)4. Attackers simply asked the Chief Security Specialist through series of emails for a
reminder as to their usernames and passwords5. HBGary's website was defaced, thousands of emails made public, people were fired
and the CEO resigned
HBGary and HBGary Federal are technology security companies that were hacked in February of 2011
Social engineering today
1. Create a "clone" of me on Facebook with public data2. Send friend requests to friends of my friends3. Assume 500 friend requests were made, and 5%
accepted4. We now have an account that can friend request
direct friends, but this time we have many mutual friends in common
At the Silver Bullet security conference in São Paulo, UOLDiveo chief security officer Nelson Novaes Neto demonstrated this in November 2011
Want my friends' phone numbers?
Social engineering today
Is your location attached to your tweet, embedded in a photo's metadata, or did you forget to make your Google Maps unlisted?
What can you do?
Everyone:• Review your privacy settings • Know what you put in the public domain• Be aware of social engineering strategies
IT best practices:• Use unique, strong passwords• Keep systems up to date and patched
Passwords
Use a long password with a mix of uppercase and lowercase letters and numbers
Ideal: Dw0lGgBeAx0h10EiothF8FnU4G7yk37LtPTIuAcuqqGkdKD8cqIN2eIMtXzriX
Consider using a password management tool
Examples: KeePass, LastPass, Firefox, Chrome
Passwords - a new model
• Consider 1 or 2 long (10+ digits) alphanumeric master passwords
• Reset all other passwords and store in password locker• All other passwords should be thought of as "disposable"
• Don't bother remembering them• Make them super long• Reset them frequently, whenever you forget them, or
don't have access to your locker storage
Reset a password? To your email it goes!
Your email account
The skeleton key to your online identity. Protect this!
Google account: google.com/accounts
Outlook / Exchange:
• Account timeout after multiple failed guesses• Phones accessing exchange should require a screen
password and allow for a remote wipe
Final PSA
• Do not have to fear online banking and shopping• Use long, unique passwords (and try a password
management tool)• Check your privacy settings on commonly used services• Google yourself and any aliases or "handles"• Protect your email account• Understand that you're more likely to be conned than hacked• For IT admins: keep services patched and up to date
Any questions?
Is that it?!
