Malicious solicitation and telephone calls to elicit personal information

Never give personal information such as your telephone number or email address if solicited to do so in person or over the telephone!

Reports have been received of persons receiving phone calls out of the blue from companies of which they have no prior knowledge to solicit personal information. This may include questions on employment status, the name of the company from which they have received an informal offer of employment, or information on their family members. Such solicitation can involve preambles such as "I received your contact information from the employment office of Keio University."
Keio University will in no circumstances provide personal information or information relating to jobs and employment to third parties, including corporations, without the prior consent of students. Please ensure that you do not give out your personal information if contacted by an unfamiliar caller.
There have also been cases of attempted solicitation of personal information such as the addresses and names of Keio students by persons who are not affiliated with Keio University on campus on the pretext of collecting information for home tutoring or part-time jobs. People have been fooled by such malicious survey or signature petitions in the past, so please remain vigilant to any such solicitations.
If you do encounter such a situation, or your suspicion is aroused, offer no immediate response and contact the employment or student services section at your base campus. At such times you are requested to confirm and report the name and contact information of the person to the extent that this is possible.
