St. Patrick’s day spam

Posted on behalf of Mathew Nisbet, Malware Data Analyst, Symantec Hosted Services
Normally in the run-up to any popular event we would expect to see a flurry of spam subjects and themes using that event. It happens all the time around events like Christmas, the olympics, and so on. One such event that is extremely popular in many parts of the world is St. Patrick's day, so naturally we expected to see an increase in the amount of spam using the subject of the upcoming St. Patrick's day celebrations to try and get people's attention.
 
However we were surprised to find that this time, the rise of related subjects just hasn't happened! There are of course still some spam appearing on the theme of St. Patrick's day, but for the most part these seem to be the same old generic pharmaceutical spam mails with a themed subject line. All of them together made up 0.003% of spam on the 16th March. So far on the 17th (St. Patrick's day itself) these themed mails have made up only 0.001% of spam.
 
Some of the subject lines we've seen are below:
 
St. Patrick''s day
Celebrate St. Patrick''s Day!
Ready for St. Patrick''s Day?
Happy St. Patrick''s Day!
