Over the past few weeks, countless Australians have fallen victim to Flubot Scams; scams that use voice-recording links and other false messaging to manipulate recipients into downloading malware onto their device.

The attacker will send a message that prompts the victim to a click a link under false pretences - typically that they have a missed voicemail, undelivered postal package or other such pressing matter to get your attention.

Once the link is clicked, the victim is taken to a page that misleads the user into thinking their device is infected with a strand of malware virus called a 'Flubot'. Finally, the page tells the victim to download an anti-virus solution to resolve the issue - which, ironically, contains the actual malware infection used to compromise the victims device.

The scam is cunningly layered, and leverages the average Australian's vague understanding and insecurities surrounding cyber-safety against them. Its acute understanding of user psychology combined with its deceptively simple delivery has managed to garner a massive infection rate across the country thus far.

The ACCC initially released a warning about Flubot scams two weeks ago, at which point they'd already received over 16,000 reports of the scam. While Flubot scams are nothing new internationally, they've proven to be a major issue domestically towards the end of 2021.

Once the users device is infected, victims can expect eavesdropping and manipulation of their confidential data to the effect of further scams - ranging from bank and identity fraud through to potential wider attacks against their place of employment or personal colleagues.

Thankfully, due to an increasing awareness of cybercrime (link) and an influx of media coverage around the scams, their effectiveness is waning significantly.

However, scammers remain agile in developing and evolving Flubot scams to maintain their profits, and a further scam is being launched off the back of this one.
