Hackers Steal 340,000 Social Security Numbers from Government Contractor
• Hackers stole 340,000+ Social Security numbers from government consulting firm Greylock McKinnon Associates (GMA) in a cyberattack in May 2023
• GMA provides litigation support to the U.S. government, including the Department of Justice - the stolen data was obtained by the DOJ for a civil litigation matter
• The breach exposed victims' names, dates of birth, addresses, medical information, health insurance details, Medicare claim numbers and Social Security numbers
• It's unclear why it took GMA 9 months after the attack to determine the extent of the breach and notify victims
• GMA brought in cybersecurity specialists to respond to the incident and notified law enforcement and the DOJ
