After years of helping protect its clients against cyberattacks, Aon PLC said in a filing with the US Securities and Exchange Commission in February that it was investigating an attack on some of its own systems.
After Aon identified the incident, it brought in third-party consultants, incident response experts and legal counsel to address the issue, the filing said.
Aon said the incident did not have “a significant impact” on the company’s operations.
The story detailing Aon’s disclosure to the SEC was the most read risk management-related story about Business insurancewebsite 2022.
About 145,000 individuals were affected by the breach of Aon̵
7;s systems, according to later court filings.The victims were notified on May 27, according to the lawsuit filed against Aon. The data breach notification sent to those affected indicated that Aon reported the incident to law enforcement agencies, including the FBI, according to the lawsuits.
The announcement said Aon had taken steps to prevent a similar event in the future, including improving the security of its networks, systems and data.
Aon was not the only insurance-related organization with concerns about cyberattacks last year. In October, Lloyd’s of London said an investigation into a possible cyber attack on its network services had found no evidence of data compromise.
“The investigation has concluded that no evidence of any compromise was found and as such Lloyd’s has been advised that its network services can now be restored,” a spokesman for the company said in an email.
