Hackers may have stolen login IDs and passwords for all Japanese House of Representative lawmakers and their secretaries and read e-mails to some of them, a lower house report said Monday.
The report said a file of coded IDs and passwords for all lower house members and their secretaries has been found in the personal computer that was infected first with a virus and became available for operation by hackers, according to the lower house secretariat.
Hackers accessed relevant mail servers more than 10 times between Aug. 24 and Sept. 7, indicating they may have read some lawmakers' e-mails, it said.
A total of 32 personal computers and servers have been found infected, although no trace of information leaks has been confirmed.
Virus-infected computers accessed unlawful websites in China and Singapore, the report said.
