More than 800 members of the Institute of Electrical and Electronics Engineers (IEEE) were recently notified that their credit card numbers and personal information may have been stolen in a November 2010 security breach.

"While the source and purpose of the security breach aren't known, IEEE's membership of technical professionals raises concerns about whether group members might be the targets of sophisticated phishing and social engineering attacks using stolen data," writes threatpost's Paul Roberts.

"A letter from the group to affected IEEE members describes the organization as a victim of a 'sophisticated network intrusion' that exposed data from an IEEE database used when members registered for an IEEE conference," Roberts writes. "The stolen information included the members' name, credit card number, expiration data and card identification number."
