The black art of spamming has grown ever more Machiavellian since the start of the year, according to new research.
Secure messaging firm FrontBridge claimed that the use of deceptive subject lines in spam has grown by half this year.
Gone are the days of obvious spam, when a cursory glance at the subject line of a mail encouraging you to 'Buy Viagra online' or 'Enlarge your breasts' was all that was needed to prompt you to hit delete.
Now, recipients are more likely to be invited to answer a question, rather than begin a quest for answers to inadequate body parts.
FrontBridge highlighted the top 10 most common subject lines used to try and con victims into opening spam.
Top of the pops is 'RE: Information you asked for', which implies that the user has requested something.
