Australian Online Privacy Bill to make social media age verification mandatory for tech giants, Reddit, Zoom, gaming platforms

The federal government has released an exposure draft for what it has labelled an Online Privacy Bill that it hopes will enhance online privacy protections for Australians through an expansion of the nation's Privacy Act.
"The goal of the Bill is to enhance privacy protections, particularly in the online sphere, without unduly impeding innovation within the digital economy," the federal government wrote in the Bill's explanatory paper.
Under current legislation, the federal government can only make two kinds of binding privacy codes, which are the Australian Privacy Principle code (APP) and a credit reporting code.
The Bill is seeking to expand the Privacy Act to allow government to create a third code specifically for regulating three classes of organisations: Social media platforms, data brokers, and large online platforms.

Cyber criminals are sending out phishing emails containing QR codes in a campaign designed to harvest login credentials for Microsoft 365 cloud applications.
Usernames and passwords for enterprise cloud services like Microsoft 365 are a prime target for cyber criminals, who can exploit them to launch malware or ransomware attacks, or sell stolen login credentials onto other hackers to use for their own campaigns.
Cyber criminals are looking for sneaky new ways to dupe victims into clicking links to phishing websites designed to look like authentic Microsoft login pages, accidentally handing over their credentials.
