Meanwhile, Satnam Narang, a research engineer at security firm Tenable, offered a word of caution to consumers who plan to get involved in the Black Friday bonanza.
"AusPost is predicting this year's Black Friday and Cyber Monday to be one of the largest online shopping peaks recorded in history," he said. "While the impact of the pandemic and the low prices draw shoppers online, cyber criminals will be chomping at the bit in anticipation of the boom.
"Some of the world's most prominent cyber threats, including malware such as Emotet and Trickbot, have enjoyed considerable success, and this year, retailers and their customers, will need to be more alert than ever before for phishing schemes.
"The use of Homoglyphs or 'lookalike' pages to fool consumers into submitting details remains a problem for consumers as these clever tactics are being used by cyber criminals to trick unsuspecting shoppers.
"Retailers also need to be on alert for vulnerabilities in plugins used to power their eCommerce sites, such as the recent WooCommerce plugin security flaw which was installed in 40,000 websites, along with the notorious Magecart card skimmer that infected over 2000 websites in a recent operation.
"Having endured such a challenging year, it's imperative that retailers take cyber threats seriously to ensure they're not undermined at this most critical time of year. Retailers must be patching, auditing plug-ins and third-party integrations as well as actively implementing content security policies."
