DESCRIPTION:Malware-containing emails can be sent to anyone. S
 ingle malware variants can be sent to tens of thou
 sands of recipients without distinction. However\,
  a small proportion of email malware is sent in lo
 w copy number to a small set of recipients that ha
 ve apparently been specifically selected by the at
 tacker. These targeted attacks are challenging to 
 detect and if successful\, may be particularly dam
 aging for the recipient. The vast majority of Inte
 rnet users will never be sent a targeted attack. T
 he few users to which such attacks are sent\, pres
 umably possess features that have brought them to 
 the attention of attackers\, and have caused them 
 to be selected for attack. Applying epidemiologica
 l techniques to calculate the odds ratio for featu
 res of malware recipients\, both targeted and non-
 targeted\, allows the identification of putative f
 actors that are associated with targeted attack re
 cipients. In this paper we show that it is possibl
 e to identify putative risk factors that are assoc
 iated with individuals subjected to targeted attac
 ks\, by considering the threat akin to a public he
 alth issue. These risk factors may be used to iden
 tify those at risk of being subject to future targ
 eted attacks\, so that these individuals can take 
 additional steps to secure their systems and data.
