Rising male with technology resume securing one target (6)
I believe the answer is:
victim
'one target' is the definition.
(eg the target of a crime)
'rising male with technology resume' is the wordplay.
'rising' is a reversal indicator (in a down clue, letters go up).
'male' becomes 'm' (common abbreviation).
'with' means one lot of letters go next to another.
'technology' becomes 'IT' (Information Technology).
'resume' becomes 'civ' (I am not sure about this - if you are sure you should give a lot more credence to this answer).
'm'+'it'+'civ'='mitciv'
'mitciv' back-to-front is 'VICTIM'.
'securing' acts as a link.
Can you help me to learn more?
(Other definitions for victim that I've seen before include "swindled one" , "One who suffers the crime" , "Person injured or killed in accident" , "Fall guy" , "Casualty or scapegoat" .)
