But, what does “a lot” actually mean? Well, it is estimated that not too long ago, in 2010, 107 trillion pieces of spam emails were sent. That it is really a lot!
You may think, well one junk email should not cause much of a problem. However, those 107 trillion of junk emails cost around $130 billion in term of loss of productivity, energy cost and increased equipment cost. That is also a lot.
Botnets are normally used to send junk around the world, but what is a botnet? Botnets, a phrase that combines the words “robot” and “network”, were designed to send millions of more junk emails per day than was previously possible.
A report by Eureka magazine identified a botnet known as Rustock. It’s is the largest botnet on record and the report says it infected over one million computers and could send 30 billion spam emails per day. It was taken down in 2011, after around five years in operation.
The question is, how many other botnets are out there?
Do you have a spam filter in place? do you receive many spam emails? Be vigilant as it is currently the preferred method of infection and distribution of malware and ransomware.
Be safe out there. Until next Malware Monday.
