Malicious Yahooligans

Overview

JS.Yamanner@m was not only the first webmail worm, but it demonstrated how web applications are equally susceptible to vulnerabilities. More so, JS.Yamanner@m demonstrates the impact of AJAX and how AJAX can be harnessed to develop more efficient web application worms. While similar worms will also generally require a vulnerability in the web application, web application vulnerabilities are not rare. Fortunately, as soon as the vulnerability is patched, the worm stops spreading.
