Odds are you have already seen a scam email at least once. Or at least know what it should look like – the gibberish email address, the incorrectly formatted body, off-looking logos and images… the list to identify a scam email is almost endless. However, scam artists are honing their craft and becoming sleeker in their presentation. It is especially becoming clear now in 2016.
In the past few months, big names such as Telstra, AGL Energy, and even the Australian Federal Police have been impersonated in emails sent to tens of thousands of Australians. All of these emails looked and sounded professional, official, and held almost no sign to doubt the source. However, despite how different these businesses are, the content of the emails all held a similar theme – malware. Those unfortunate enough to click a link or download an attachment instantly found their computer infected with it.
The malware attached to these emails have varied greatly, from the more common types of malware that have been reported in these incidents are spyware and ransomware. Spyware burries itself into your computer and silently gathers and sends information – like a spy – to the sender. This is how things such as credit card details, passwords, and keystrokes can be gathered without your knowledge. Ransomware is almost the polar opposite – it locks you out of your computer and refuses to give you access again unless you pay money.
Ransomware, especially with the AGL Energy incident, is becoming alarmingly common in these targeted attacks, with its use seeing a dramatic increase this year. With the computer being held hostage for nearly $900 once activated, it is a painfully expensive reminder to be careful of what you click. It can strike anyone as well – in the US, the University of Calgary had to pay nearly $16,000 when their computers were infected with ransomware.
Odds are that the next big email hoax is around the corner, and we need to be prepared for it.
"6 years ago I contacted Caboodle Web to help my fledgling business with a web presence. What a journey they have assisted us with. In this period our business has grown from a small part-time operation to a business with a multi-million dollar turnover and 7 staff. Of course this has not all been down to Caboodle building us a state-of-the-art website (one that not only looks great but sells too!) but we could not have achieved this as easily without having a web partner who is responsive to our needs and able to add value to our business. If you have had enough of dealing with other web developers and need a dedicated, professional partner I would recommend that at the very least you sit down with Caboodle and discuss your needs. Unlike others they will not promise you the earth but will give you an honest assessment of your needs and will then deliver. I am to discuss my experience of dealing with Caboodle with anyone that wants to call me."
