The pandemic, ongoing lockdowns and tax return time are leading to a perfect scam storm, says Dr Suranga Seneviratne from the School of Computer Science.
Dr Suranga Seneviratne is a computer scientist and cybersecurity expert from the Faculty of Engineering who warns that conditions caused by the pandemic are leaving Australians vulnerable to a scam surge. He provides timely advice for on how to spot scams and avoid becoming a target.
"The COVID-19 pandemic has hit Australia again. Many of us were caught off guard and we have all had to quickly react and adjust. Changed work conditions - or lack thereof, home-schooling, social isolation and information overload are making many of us,even the tech savvy, vulnerable to scams," said Dr Suranga Seneviratne.
"Scammers target vulnerability and thrive on disorder - current conditions are the perfect breeding ground for this type of nefarious activity.
"Now, more than ever, we should be on high alert for possible cyber-crime and scam activities targeting us."
Lessons from lockdown 1.0"Last year we witnessed several pandemic-specific scamming activities. The early days of the pandemic saw attempts to distribute malware using apps and websites disguised as providing COVID-19 information," said Dr Seneviratne.
"There were also phone, SMS, and email campaigns around the world where the attackers targeted mobile users with convincing stories, such as pandemic relief packages, test results, information about travel restrictions, and early access to vaccination. During the same time, regular scam activities - such as romance scams and fake advertisements - also increased locally as well as globally.
"For example, according to the Australian Competition and Consumer Commission (ACCC)’s latest report [link?], losses from scam activities sky-rocketed in 2020 - increasing by a staggering 23 percent compared to 2019. The US Federal Trade Commission reported similar trends in the US."
What’s happening this time around?"While it remains to be seen whether scam activities have increased during the current outbreak, there’s evidence that attackers are "seizing the moment" with crafty stories designed to exploit people’s heightened vulnerability," said Dr Seneviratne.
"Just last month, Australian mobile users were targeted by the ’Flubot’ scam. Targeted users received a seemingly innocuous SMS with a link to a supposed voice mail message. Once the link was clicked, users were asked to install a voicemail app, which was in fact malware. Some thought this message was related to their COVID test results.
"During the pandemic, people have been getting calls from unknown numbers for all sorts of reasons, and not all of them have been nefarious. This increased communication, coupled with many people being more preoccupied than usual, has caused many otherwise cautious people to absent-mindedly click malware links or answer calls from scammers.
"Business emails have also been compromised by scammers. Some businesses or individuals may be behind their payments due to the pandemic or dealing with challenging remote working conditions. Attackers have been pretending to be suppliers, trying to scam money from businesses."
"Fake postage or logistic texts and emails, claiming to be DHL, Australia Post and Toll have been rife too, with scammers capitalising on the increase in orders and trade by post."
"Now that we are in a new financial year, increasingly, scammers are posing as the Australian Taxation Office and are requesting large sums of money. There have also been instances where people have received voicemails telling them they have a warrant out for their arrest because of tax evasion."
