In this report, we will explain incidents that occurred between April and June 2010, and also examine trends in the Year 2010 Issues on Cryptographic Algorithms, our observations on the backscatter caused by DDoS attacks, and trends in the vulnerability information circulation.
In this report, we will present an overview of spam trends for week 13 through week 25 of 2010. China was the top regional source of spam. The ratio of spam sent from European countries such as Germany and Great Britain is also increasing.
Internet traffic volumes which had been increasing at a comparatively stable annual rate of approximately 30% until now, declined sharply by almost 20% in the beginning of January 2010. It is said that the reason for this was the amended Copyright Act that makes the download of copyright infringing content illegal. Here we will explore the cause of this drop in traffic by comparing traffic and port usage levels for the week starting May 24, 2010 with data for 2009.
