  With the generalization of mobile communication systems, solicitations of all
kinds in the form of messages and emails are received by users with increasing
proportion of malicious ones. They are customized to pass anti-spam filters and
ask the person to click or to open the joined dangerous attachment. Current
filters are very inefficient against spear phishing emails. It is proposed to
improve the existing filters by taking advantage of user own analysis and
feedback to detect all kinds of phishing emails. The method rests upon an
interface displaying different warnings to receivers. Analysis shows that users
trust their first impression and are often lead to ignore warnings flagged by
proposed new interactive system.
