The New Straits Times Online tells an amusing story about a secret agent scam in Malaysia:

The opportunity to work as a secret agent or investigate high-profile cases involving VIPs seemed like a dream come true for 36 people who signed up to join the Federal Special Forces of Malaysia.
Led by what police sources described as a charismatic leader, the 36 men, aged between 20 and 30, signed up thinking they would serve the country in the field of national security.

“Recruits were told that selected people would get important tasks, including intelligence gathering, which carried great responsibility as it involves national security,” a source told the New Straits Times.

How do you confirm the authority of a secret agency when it is secret? Apparently you can check the registration.

“The movement was registered with the Registrar of Companies while the authority to form an enforcement unit lies with the Home Ministry.”

Just ask for their tax ID.
