Unwanted email has long stopped being just a source of advertising services or products. The time it takes to erase all spam messages from your inbox is not the only drawback of this threat.
It’s not a secret that cybercriminals use spam as a channel to spread malware: malicious objects are, as a rule, attached to the message. Spam might also contain a link to malicious web resources serving the ground of a phishing attack or are injected with a malicious code.
That means, once in the inbox, such emails would become an open door for a banking Trojan and, as a result, become a means of stealing money from online banking systems. It’s rare to find someone who has never encountered any type of spam in their life. Some get regular mails from a dubious sender and some literally bathe in tons of such messages every day. A recent research conducted by Kaspersky Lab in association with B2B International revealed that 64% of respondents consider spam one of the most serious threats.
One should take into consideration that cybercriminals constantly improve their social engineering methods, which are then used to elaborate efficient phishing messages. For instance, our experts have been registering the growth of phishing messages disguised as financial documents. Those could be: traffic fine notifications, bank transfer confirmations, alerts about overdue payments, money transfers, online orders, as well as claims, e-tickets, and the like. Among such there are faux messages from government agencies, online shops, booking services or airlines. Sometimes culprits take advantage of holidays or major events: for example, last year, scammers used FIFA 2014 World Cup as a bait.
Elaborate techniques are used to lure users into a trap: they create an urge to open the message, then open malicious attachments or click on a malicious link included into the body of the mail. Our experts estimate the share of spam in the email traffic as more than half of the total. With that in mind, and considering the level of skills the scammers employ, technologies able to battle this threat are critical.
