Yet another idea:
Mission: Confirm that we have a spy in our systems, Check one of our worker
Probably appearing at Uplink rating Intermediate
The mission is you have got the workers name and an Internet provider (ISP) (probably you need to figure out the ISP, see EDIT2), and the rival company's name. You need to break in his Internet providers database, get his IP, use PCForce on the computer, get in his computer, and check the IPs in the logs with IP lookup, and if he has some connection with the rival company (like connected to ISM, probably password authentication accepted?), then reply with a yes in the mail, if there is no connection with the rival (probably just some pornosite IPs
), then reply with no.EDIT: Also, you could use PCs for Denial.
EDIT2: You can harden the "Frame somebody for something" with only giving out the name and the ISP's name will be in the Social Sec database
