Jun Ying accused of dumping stock options prior to September 2017 breach disclosure UPDATED An Equifax executive who was tipped to become the credit rating agency's next global chief information officer has been charged with insider trading. In a statement released today, the Securities and Exchange Commission (SEC) said it has charged Jun Ying, a former CIO of a US business unit of Equifax, with insider trading prior to the group's data breach announcement in September 2017. According to the SEC's complaint, Ying allegedly used confidential information entrusted to him by the company to conclude that Equifax had suffered a serious breach. The SEC alleges that before Equifax's public disclosure of the data breach, Ying "exercised all of his vested Equifax stock options" and then sold the shares, reaping proceeds of nearly $1 million. According to the complaint, by selling before public disclosure of the data breach, Ying avoided more than $117,000 in losses.
