Antioch University has revealed social security numbers and other personal data belonging to more than 60,000 students, former students and employees may have been compromised by multiple intrusions into its main ERP server.
The breaks-in were discovered 13 February and involved a Sun Solaris server that had not been patched against a previously disclosed FTP vulnerability, even though a fix was available for the flaw at the time of the breach, university CIO William Marshall said Friday.
The university was alerted to the breach while IT officials were investigating a separate virus that had also infected the system and was broadcasting obscene material from it, Marshall said. That particular virus was programmed to broadcast the material on the 13th of each month and was detected by the university's anti-virus software, when it started doing so on 13 February, he said.
"When we went in and did further investigation, we found that there was an IRC bot installed on the system," Marshall said.
According to Marshall, the university ERP system, based at Antioch's main campus in Ohio, appears to have been breached on three separate occasions.
The first break-in occurred 9 June, 2007, when intruders gained remote access to the ERP server via the unpatched Solaris FTP vulnerability. "The first one was an automated attack. It happened very, very quickly," Marshall said. The IRC bot discovered 13 February appears to have been installed on the system one day after the initial intrusion, he said. Forensic analysis shows that the third time the server was illegally accessed was 11 October, 2007, Marshall said.
As far as the university can tell, the data on the server appears not to have been illegally downloaded or copied by the intruders, he said.
Following the discovery of the intrusions, the infected server was taken offline, the data on it was backed up and the operating system was reinstalled from scratch, Marshall said. "That's the only way we can be sure that we got everything on it that shouldn't be there," he said.
The compromised server contained information on current and former students and employees across all of Antioch's six campuses going back to 1996, Marshall said.
The system also contained information on individuals who had applied to Antioch but may have never attended the university and information on vendors who may have supplied their social security numbers in order to get paid. The compromised data included names, addresses, social security numbers, telephone numbers and academic records.
Notices informing the affected individuals about the breach and urging them to take measures to protect against ID theft were sent out last week, Marshall said. There are a couple of reasons for the delay, Marshall said. First, the university needed at least two weeks to understand the full scope of the breach, he said. The university also did not want to compromise investigations by law enforcement authorities by disclosing the breach prematurely, he said.
