International. A total of 85 daily custom attacks occurred during the month of April, according to the MessageLabs Intelligence report by Symantec. This is the highest figure since March 2009, when 107 events were reported each day.
Another point of the report indicates that the increase in the use of abbreviated URLs is being used as a trap for people to enter advertising sites, something that is known as "click fraud".
Symantec reveals that during April, one in 168.6 emails contained malware and personalized attacks accounted for 0.02% of that virus, which means that in a period of six months they have increased 10.5%.
The report also indicated that spam, in April, decreased globally by 6.4% since March 2011 to 72.9%, while the global proportion of viruses sent by email increased 0.114%, both attacks coming from malicious and previously unknown sources.
