Former Yahoo Software Engineer Pleads Guilty To Using Work Access To Hack Into Yahoo Users’ Personal Accounts
Defendant admits illegally copying images and videos from about 6,000 Yahoo accounts
SAN JOSE – Reyes Daniel Ruiz pleaded guilty in federal court in San Jose today to hacking into the accounts of thousands of Yahoo users in search of private and personal records, primarily sexual images and videos of the account holders, announced United States Attorney David L. Anderson and Federal Bureau of Investigation Special Agent in Charge John F. Bennett.
In pleading guilty, Ruiz, a former Yahoo software engineer, admitted to using his access through his work at the company to hack into about 6,000 Yahoo accounts. Ruiz cracked user passwords, and accessed internal Yahoo systems to compromise the Yahoo accounts. Ruiz admitted to targeting accounts belonging to younger women, including his personal friends and work colleagues. He made copies of images and videos that he found in the personal accounts without permission, and stored the data at his home. Once he had access to the Yahoo accounts, Ruiz admitted to compromising the iCloud, Facebook, Gmail, DropBox, and other online accounts of the Yahoo users in search of more private images and videos. After his employer observed the suspicious account activity, Ruiz admitted to destroying the computer and hard drive on which he stored the images.
Ruiz, 34, of Tracy, California, was indicted by a federal Grand Jury on April 4, 2019. He was charged with one count of Computer Intrusion, in violation of 18 U.S.C. § 1030(a)(2)(C), and one count of Interception of a Wire Communication, in violation of 18 U.S.C. § 2511(1)(a) and (4)(a). Under the plea agreement, pled guilty to the count of Computer Intrusion.
Ruiz is currently on release pursuant to the conditions of an unsecured $200,000 bond.
Ruiz’s sentencing hearing is scheduled for February 3, 2020 at 1:30 p.m. before The Honorable Edward J. Davila, U.S. District Court Judge, in San Jose. The maximum statutory penalty for each count in violation of Computer Intrusion, 18 U.S.C. § 1030(a)(2)(C), is five years imprisonment and a fine of $250,000, plus restitution. However, any sentence will be imposed by the court only after consideration of the U.S. Sentencing Guidelines and the federal statute governing the imposition of a sentence, 18 U.S.C. § 3553.
