If you do become a target, the methods used to obtain information from you or about you could include any one or all of the following: elicitation, eavesdropping, assessment of political attitudes, identification of weaknesses (for alcohol, drugs, money, sex), clandestine microphones (in hotel room or office), "bag operations" (surreptitious entry into hotel room to steal, copy, or download information), or electronic monitoring (of telephone calls, fax transmissions, or computer emissions).
The likelihood of your being a target depends a great deal upon which country you are visiting, the purpose of your visit, and how attractive you are as a target. Any intelligence activities directed against you will usually be conducted in an unobtrusive and nonthreatening manner, although in some cases a foreign intelligence service may employ more aggressive provocation tactics.
