Refinements to URL scanning

We made a few adjustments to the URL scanning code in the past couple of weeks to allow it to be more effective as the spammers mutate to avoid earlier block techniques.

  • We added a number of handlers to spot redirectors.
  • We’ve adjusted the list of tell-tales that accompany trojan executables
  • Improved spotting of Image-Only spam.
  • Greater range of countries and formats for telephone numbers.

We’ve got a few more steps before we can administer the spammed telephone numbers via our management interface but for the time being we’ve added a selection of the more egregious examples to the database manually.
