The MBTA and the company that runs its commuter rail services are looking into a possible hack after alerts went out warning commuters that service ``was delayed until further notice.''

The T sent a notice out minutes later Wednesday morning telling commuters to disregard the alert.

Mac Daniel, a spokesman for Keolis Commuter Services, says the alerts that went out at about 5:30 a.m. were ``possibly a hack.''

A T spokesman, however, says it doesn't look like a hack, but more like a ``technical issue.''

Daniel says the false alert applied to commuter rail lines out of South Station, which are running at about 62 percent of a normal weekday schedule as the system continues recover from a series of snowstorms that crippled the Boston area's public transit system.
