Analyzing Security Implications of URL Shortening Services
With the advent of social networks
and Twitter, where public messages are required to fit into 140
characters, compression of long URLs (which often exceed this character
limit by themselves) became crucial. A consequence was the widespread
use of so called URL shortening services, which compress a URL of
arbitrary length to below 20 characters.
This thesis analyzes implications on security and privacy when using URL shortening services. It is evaluated what risks exist for the privacy of users, the security of their machines (browser, operating system), and for the security of server machines. Furthermore, the use of URL shortening services in malware distribution and email-spam is examined.
