The Guardio Labs research team has revealed a security flaw, dubbed MyFlaw, in the Opera web browser for Windows and macOS, allowing execution of files on the operating system. The flaw exploits the My Flow feature, prompting updates on Nov 22, 2023, to address it. The vulnerability emphasizes the need for improved browser security.
Based on the meeting notes, the key takeaways are:
1. Disclosure of a security flaw in the Opera web browser for Windows and macOS, allowing remote code execution through the My Flow feature.
2. Exploitation of a long-forgotten version of the My Flow landing page hosted on the domain “web.flow.opera.com” to transmit an encrypted malicious payload and execute it on the victim’s system.
3. Highlighting the increasing complexity of browser-based attacks and the need for design changes at Opera and improvements in Chromium’s infrastructure.
Let me know if there is anything else you would like to add or modify.
