"SoftWar" from The Hacker Files #4 (DC, 1992) by Lewis Shiner, Tom Sutton and Mark Buckingham
Not exactly splashy, but I love series that take place in the margins of a superhero universe. Books like Chase, Time Masters, Damage Control and this, The Hacker Files, about a computer expert who quits the company he's working for when he discovers a conspiracy. The book also used Oracle, but Tom Sutton's anxious art turned awkward whenever superheroes showed up. Still, I fondly remember this 12-issue series. It was more overtly political than any other DC comic and I enjoyed its 90 degree approach to the DCU.
