Transhumanity is in the middle of a cold war. The battle of Locus demonstrated the great difficulties of conquest against post-singularity peoples, but the inner and outer systems have certainly not given up on their rivalry. The Planetary Consortium is continually seeking to destabilize the Autonomist Alliance, while the autonomists in turn seek to undermine the PC and hypercorp.
One of the most active weapons in the autonomist arsenal are the sleepers. The inner-system economies rely heavily on infugees, much more than anyone else. Infugee databases should be well protected, and infugees should be subject to careful screenings, but of course no security is perfect. It has become common practice for anarchist firebrands to hack into infugee databases and copy a fork of themselves into it. They then do their best to be a good candidate for an indenture contract. At whichever job they end up, they will attempt to sabotage industry, incite rebellion among their fellow indentures, assassinate key figures, and in general take advantage of any opportunity to undermine the PC.
Sleepers are often given a programmed identity.
Plot Hook: Anti-Autonomist factions within Firewall see attempts to destabilize the PC as potential x-threats due to the high likelihood of war, economic collapse and balkanization in the event of success. The players are tasked with preventing the assassination of a particularly important hyperelite executive, but the executive cannot know of the player's intervention.
Plot Hook: An anarchist sleeper saboteur has plans to disable key elements of a Direct Action munitions fabrication site, and calls on an @-rep favor from one of the players for help.
