    Within a short time period of less than 24 hours, cybercriminals have already taken advantage of Monday’s explosion at the Boston Marathon as a newsworthy item. My colleague Mary Ermitano-Aquino noted a spam outbreak of more than 9,000 Blackhole Exploit Kit (clarification below) spammed messages, all related to the said tragedy that killed at least three people and injured many more. Some of the spammed messages used the subjects “2 Explosions at Boston Marathon,” “Aftermath to explosion at Boston Marathon,” “Boston Explosion Caught on Video,” and “Video of Explosion at the Boston Marathon 2013″ to name a few. Below is a spam sample she found:

This is a mistake, as this ignores the fact that many of the “attackers” are actually systems that have been infected with malware and used to carry out attacks. We will use the data gathered by the Smart Protection Network.

    On a typical day, the traffic to one of the websites targeted in this attack overwhelmingly (more than 90%) comes from within Israel itself. On the day of the attack, however, this was reversed, with only 9% of the traffic we saw coming from inside the country:
