Some interesting quotes from Ars Technica’s summary of Microsoft’s latest Security Intelligence Report (linked below). The first one talks about spam volumes. We’re talking about billions of messages a month here, which is mind-boggling if you try to imagine this.
Microsoft … attributes the drop [in spam volumes] primarily to the “takedowns of two major botnets: Cutwail, which was shut down in August 2010, and Rustock, which was shut down in March 2011 following a period of dormancy that began in January.” Consequently, the biggest drops in e-mails blocked occurred in September 2010, when spam dropped to about 65 billion messages, and in January 2011, when it fell under 40 billion. The low point was in May 2011, with about 22 billion, but it ticked up again in June.
The next quote is about Java, and it’s not really good news for Java:
The most commonly observed exploits target vulnerabilities in Java, specifically the Java Runtime Environment, Java Virtual Machine, and Java SE in the Java Development Kit. “Java exploits were responsible for between one-third and one-half of all exploits observed in each of the four most recent quarters,” Microsoft said.
