Abstract
Summary: ``We show several hardness results for the minimum hacking problem, which can be described roughly as the problem of finding the best way to compromise a target node given a few initial compromised nodes in a network. We give several reductions to show that minimum hacking is not approximable to within $2^{(\log n)^{1-\delta}}$ where $\delta=1-{1\over\log\log^cn}$, for any $c<1/2$. We also analyze some heuristics on this problem.''
