GUEST OPINION:  Australia’s healthcare sector is consistently targeted by cybercriminals, having reported the highest number of data breaches from all Australian sectors over the last five years, according to the OAIC Notifiable Data Breaches Reports. The risk of ransomware specifically is increasing, with the recent analysis of a global sample of reported ransomware attacks showing that over one in five attacks (21%) was targeted at healthcare organisations in 2023/24, up from 18% the year prior.

GUEST OPINION:  Predicting the future isn’t easy, but you can anticipate what is likely to happen by looking at how things have evolved over the past year. This year again, Barracuda asked colleagues who work on the security frontlines about the things they witnessed in 2024 and expect to see in 2025.

GUEST OPINION: How does credential stuffing work? Initially, a 3rd party service is breached, and credentials are stolen. There have been many high-profile organisations that have had their customer’s user credentials stolen, I don’t wish to pick on anyone in particular. Usually, it is a combination of email address, username, and password (typically hashed/encrypted). These credentials are then published on the dark web for bad actors to purchase and use in automated credential-stuffing attacks. The credentials are then used to automate login attempts on other online services to see if these same credentials work.
