Small businesses are increasingly being targeted by computer hackers because their security is not as tough as larger companies, according to a Government report.
Cyber-crime is estimated to cost Australian businesses up to $1 billion every year, and the report claims 60 per cent of businesses hit by a cyber attack went out of business within six months.
However, small business-owners have largely indicated they did not believe they were in danger of being targeted.
The report shows only a quarter of small business owners thought they were at risk of having their data stolen and held to ransom, and less than half kept their anti-virus software up to date.
Only 2 per cent of small businesses treated protections against hacking as a priority.
Cybersecurity expert Matt Tett said many people mistakenly believed large companies, like cheating website Ashley Madison, were more likely to be targeted by hackers.
