You can see that the victim net is labeled ( tri_des_B/des3/u0/n_676).
To find the agressor net(s), look at the "constituents" section. The agressor net is tri_des_B/des3/u0/n_672. If you have a glitch or noise-on-delay for your victim net, this agressor is the one you want to separate it from. Likely, these two nets have a long parallel run. The "net" that matches the victim, but has a ~ in front of it, is all the other little things in the design that add up to SI effects, so it's not a real net you can look at in the design. Just address the real aggressor and you should be able to fix the SI problem.
