Cape Town - Computer users should be on guard that criminals will try to exploit any major event in order to compromise machines to steal personal and financial information.

With the death of former South African president Nelson Mandela, it is likely that hackers will send e-mail or even text messages purportedly from a "distant Mandela relative" offering a target cash for services or a business venture.

These messages are inevitably spam and they often have malware attached.

Spam remains that most pressing concern of PC users with about 68% more concerned about unsolicited mail that PC virus infection, a survey conducted by O+K Research found.

But spam is not confined to e-mail. Spammers have also evolved to exploit social networks.

Prolific spammers

"Social networks are not immune to spamming tactics; you see it also on forums on the internet. People are discussing a certain topic and suddenly there's a completely unrelated comment with an advert," managing director of Dr Pieter Streicher recently told News24.

An emerging social network engineering scam is for the user to be sent a mail with a message that a Facebook user has shared her private pictures and you have to click a link to access them.

A large-scale survey done by researcher Giovane Cesar Moreira Moura in 2013 found that 50% of spam was confined to only 20 ISPs.

Of those, Spectranet in Nigeria was one of the most prolific with 62% of all the addresses controlled by that ISP sending out spam, the BBC reported.

One of the typical scams to hit South Africans during 2013 was a "notification" from Sars to indicate that a taxpayer had received a substantial payment. The attachment in the mail was generally a link to an attack website designed to steal credit card information.

Security company Kaspersky Lab identified the top threats for South African users during 2013, with the malicious website dominating the landscape.

The list below indicates the position, name of attack, and the percentage of times seen by Kaspersky experts.
