Pada Q1-2009 18% komputer zombie berasal dari US
botnet model
Dalam laporan yang dikeluarkan oleh McAfee, Quarter pertama di tahun 2009 jumlah IP yang terserang botnet bertambah hampir 12 juta atau bertambah 50% sejak tahun 2008. Dari keseluruhan komputer yang terinfeksi 18% berasal dari US, kemudian diikuti China 13.4%. Sebelumnya pada Quarter keempat China menduduki peringkat pertama dengan presentasi 15.8% dan Amerika 15.4%.
In this quarter, we detected nearly twelve million new IP addresses operating as €œzombies,€ computers under the control of spammers and others. This is a significant increase over the levels from the last quarter of 2008, with an increase of nearly 50 percent. The third quarter of 2008 also posted a record number of new zombies, but it was exceeded this quarter by one million. And although the spam volume levels have not yet recovered from the McColo shutdown, the activity level of new zombies indicates that the spammers are working hard to regain the infrastructure lost and that volumes will return to previous levels sometime soon.
Selain itu juga Amerika masih tertinggi dalam kategori pengirim spam. Pada quater pertama 2009, sebanyak 35% spam terkirim dari Amerika, dan dari keseluruhan spam yang beredar 25% berkaitan dengan drugs alias obat-obatan.
U.S. automakers may be struggling with manufacturing and sales problems, but spam production from the United States continues to lead the world, accounting for 35 percent of global spam output. Although spam command-and-control operations are an international infrastructure, spammers still favor using computers from the United States to manufacture spam. The top 10 countries dominate in spam production, contributing nearly 70 percent of the total and far outdistancing the other 200-plus countries in the world.
