Spam Emails have existed almost as long as internet has. From cash prizes to fake Rolex watches to endless supply of Viagra, spammers use any form of means to make readers open the email and click the link – which keeps spam alive.
Last month, computer security experts shut down one of the world’s biggest botnets Grum. Grum was run by a group of cybercriminals who specialised in sending spam selling pharmaceutical products, Viagra pills and fake Rolex watches.
In a span of four years, Grum was responsible for 18 per cent of the global spam, sending about 18 billion messages a day.
Other botnets, like Lethic and Cutwail, world’s largest and second largest, are still out there, but they are being hunted down.
“Spam can definitely be reduced – we are proving that already,” said FireEyes’s James Todd.
Last year, the Rustock botnet was taken down by Microsoft and FireEye.
“Ultimately, the true death of spam is going to be prevention of infection of all those computers – users like you and me – who are unknowingly being part of a spambot or a botnet,”he added.
Although only 5.3%of world’s internet users live in India, India contributes more than 11% of world’s spam, followed by Italy and South Korea. The figures below are the worst-spam relaying countries from April to June.
