Logic bomb: new kind if insider cyber attack
Date: September 22, 2007Source: The Register
A former Unix system admin at Medco Health Solutions, a big US drugs prescription management firm, has admitted to planting malicious code that would have destroyed massive amounts of critical patient information.
Yung-Hsun Lin pleaded guilty in US District Court in Newark, New Jersey on Wednesday over the charge of transmitting code that would cause damage to a protected computer in excess of $5,000. The crime carries a maximum penalty of 10 years in prison and a $250,000 fine.
Lin had allegedly planted a "logic bomb" computer virus on Medco's systems in October 2003 over concerns he would lose his job after the company was spun off from Merck &Co that year. The code was designed to delete nearly all data from 70 servers, which included patient files listing adverse affects to particular drugs and billing information.
