Shellshock just one tool in hackers’ cyber arsenal

Silent thief: The Shellshock vulnerability went unnoticed for more than 20 years.

Online shoppers need to be extra vigilant against malicious links during the holiday shopping season, warns Adam Turner.

Unwitting Australians click on more than 15 million malicious internet links every month, lured by increasingly sophisticated attempts to infect their computers and steal valuable information.

Australians clicked on more than 45.5 million malicious links in the third quarter of 2014, up from 39 million in the three months before, according to security vendor Trend Micro’s third-quarter security roundup┬áreport. This ranks Australia fifth in the world for countries with the highest number of visits to malicious sites after the United States, Japan, France and Italy.

The growing threat from malicious links is partly attributed to September’s discovery of the Shellshock security flaw in many web servers. Among other things, the Shellshock flaw lets attackers hijack legitimate web pages and secretly download malicious software on to the computers of people who visit the site, known as a drive-by download.

The Shellshock vulnerability went unnoticed for more than 20 years, suggesting the likelihood of more long-undiscovered vulnerabilities lurking within with operating systems and applications.

Meanwhile, the threat from vulnerabilities in mobile devices and apps is also increasing, with ransomware targeting mobile devices along with desktop computers.

Ransomware encrypts the contents of a device and demands a ransom for precious files, such as photographs, to be returned. One of the latest ransomware threats involved fake emails, purporting to be from Australia Post, with an attachment that claims to contain details of parcel deliveries but in fact encrypts the computer’s hard drive and demands payment.

The latest report is a clear indication that Australian consumers still need to be educated about their online vulnerability, especially as cyber threats become more complex, says Trend Micro’s Australia and New Zealand consumer director, Tim Falinski.

“Consumers need to be extra vigilant heading into the holiday shopping season and new year sales, which is typically a time of year that sees an increase in cyber crime.”
