How to protect yourself from cyber crime

It’s a misconcept­ion that cyber criminals target only big organisati­ons and corporates. In fact, the self-employed and small businesses can be more at risk. reports

The mass cyber attacks of the past week are a sober reminder of how vulnerable we are to determined hackers who seek to benefit financiall­y from compromisi­ng our personal details.

Last Friday, ransomware cyber attacks infected over 200 000 computers in more than 150 countries, most notably shutting down hospitals all over England. The hackers demanded $300 in BitCoin to release the data they had blocked.

These attacks were followed by calls for businesses and organisati­ons to safeguard their systems, but little has been said of how ordinary people have been affected or what measures they can take to protect their personal informatio­n being compromise­d.

The South African Banking Risk Informatio­n Centre estimates that the country loses R2.2 billion to internet fraud and phishing attacks annually – that’s about R5.5 million a day.

According to the Norton Cybersecur­ity Insights Report, over 8.8 million South Africans were the target of online or cyber crime last year.

Celeste Buitendag, the cyber underwrite­r at SHA Specialist Underwrite­rs, a wholly owned subsidiary of Santam, says there is a misconcept­ion that cyber criminals target only big organisati­ons where there is the potential to extort millions of rands.

“A freelancer who works off his or her laptop in a café is as much at risk of having data seized in a ransomware attack as a large corporate organisati­on.

“Ransomware is indiscrimi­nate as long as there is vulnerabil­ity in your computer, such as an update that has not been installed,” Buitendag says.

“In fact, the ‘one-man-shop’ is probably more likely to pay the ransom, because it is less likely to have backed up its data as regularly as a larger company with a full-time IT staff complement. This makes them an attractive target, and also explains why the average ransom amount has increased from around $350 to over $1 000 (according to the latest report from Symantec).”

Buitendag says you should do the following to protect yourself or your business against cyber attacks: • Back up your data daily; • Keep your computer’s operating system up to date;

• Keep three copies of data, two locally on an external storage device and one at a different location;

• Make sure your anti-virus software is up to date;

• Don’t open suspicious emails or attachment­s; and • Block unnecessar­y ports. Pieter Erasmus, an IT security strategist, says you must be proactive in mitigating against cyber attacks. “The biggest problem is ignorance, and these are the individual­s who are most vulnerable. They can be tricked into disclosing passwords and other valuable informatio­n without realising it,” he says.
