During a targeted attack on hubs, the integrity of a network will fall apart relatively fast. Since small nodes are predominantly linked to hubs, the targeted attack on the largest hubs results in destroys the network in a short period of time. The financial market meltdown in 2008 is an example of such a network failure, when bankruptcy of the largest players (hubs) led to a continuous breakdown of the whole system. On the other hand, it may have a positive effect when removing hubs in a terrorist network; targeted node deletion may destroy the whole terrorist group. The attack tolerance of a network may be increased by connecting its peripheral nodes, however it requires to double the number of links.

在对枢纽进行特定的攻击时，网络的完整性会相对较快地被破坏。由于小度节点大量的链接到枢纽，因此对最大枢纽的攻击会在短时间内破坏网络。2008年的金融市场崩溃就是这种网络失灵的一个例子，当时头号玩家（枢纽）的破产导致了整个系统的持续崩溃。<ref>{{Cite journal|author1=S. V. Buldyrev |author2=R. Parshani |author3=G.
