Engineers at UNSW Sydney and Monash have developed an innovative way of sending hidden information that’s hard to intercept. Using a phenomenon known as “negative luminescence,” the system works by making signals blend perfectly into the background of natural heat radiation, such as can be seen with a thermal camera.

To outside observers, it looks like no data is being sent at all. Only a receiver with the right equipment can pick up the hidden message.

Because the very act of communication is invisible, the method makes signals almost impossible to intercept or hack. That means it could one day offer a powerful new security tool for sensitive communications in fields like defense and finance.

Rust-based VENON malware targets 33 Brazilian financial platforms using advanced evasion and overlays, enabling credential theft.

Hackers contacted employees at financial and healthcare organizations over Microsoft Teams to trick them into granting remote access through Quick Assist and deploy a new piece of malware called A0Backdoor.

The attacker relies on social engineering to gain the employee’s trust by first flooding their inbox with spam and then contacting them over Teams, pretending to be the company’s IT staff, offering assistance with the unwanted messages.

To obtain access to the target machine, the threat actor instructs the user to start a Quick Assist remote session, which is used to deploy a malicious toolset that includes digitally signed MSI installers hosted in a personal Microsoft cloud storage account.
