A 43-year-old Baton Rouge man recently fired by Georgia-Pacific has been indicted and arrested for a cyberattack on the company’s computer system, U.S. Attorney Walt Green said Wednesday.

Brian P. Johnson, a former systems administrator for the company, is charged with intentionally damaging protected computers and faces up to 10 years in prison if convicted, Green said.

A few hours after his Feb. 14 firing, Georgia-Pacific computer systems were attacked from a computer address assigned to Johnson, according to an FBI affidavit. The company experienced multiple system failures over the next several days due to continued attacks believed to have been instigated by Johnson, the affidavit alleges.

The cyberattacks caused more than $5,000 in losses to Georgia-Pacific entities, Green said.

Johnson was arrested Wednesday. A federal grand jury indicted him last week.
