Trustwave researchers have detailed a new phishing method that aims to bypass Instagram accounts' two-step verification. A misleading email message and login page lead users to reveal their credentials and a temporary six-digit backup code.

To prevent losing their account, the user is prompted to log in within 12 hours using a specific link.

Prompt injection is an unresolved issue that poses a significant threat to the integrity of Large Language Models (LLMs). This threat is heightened when LLMs are transformed into agents that interact directly with the outside world, using tools to retrieve data or carry out actions. Prompt injection techniques can be used by malicious actors to produce unintended and potentially harmful output by distorting LLMs' reality.
