Black Holes a Major Security Concern
Scotiabank recently named black holes as its major security issue for 2011. They encountered a concerted effort by hackers to draw their people into them through setting a variety of traps (some 50 types of them they said). When users click on the URLs in the traps, they are drawn into a series of illicit domains that search their computers for vulnerabilities and then plant viruses that exploit these vulnerabilities. The viruses are shielded so that the anti-virus software can't recognize them. The most effective way to safeguard against these black hioles is to block the URLs that lead to them, but this is a big job and depends on having a knowledge of what those URLs are. Scotiabank managed some success in dealing with them, as explained in this article.
