"Google Pixel's Markup Tool Vulnerability Exposes Redacted Images"

A vulnerability in Google Pixel's built-in Markup tool, dubbed "Acropalypse," allowed partially recovered edited or redacted images, including those that have been cropped or had their contents masked, for the past five years. The flaw was discovered by security researchers who reported it to Google in January 2023, and the company fixed it via an update released on March 13, 2023. However, any images shared in the past five years are vulnerable to the Acropalypse attack, and nothing can be done to remediate this. The vulnerability could expose sensitive information that the image creator redacted using Pixel’s Markup tool before sharing the media with others or posting it online.

"Pixel phones' Markup tool poses serious security risk"

A security flaw in the Markup tool on Pixel phones, dubbed "Acropalypse," allows hackers to un-redact and uncrop edited screenshots, potentially revealing sensitive information. The vulnerability has been fixed with the March 2023 security update, but screenshots shared before that remain vulnerable. The flaw can be exploited only if the original screenshot file is shared, and messaging and social media apps that compress and re-process shared images are not vulnerable. A technical demo has been devised to check if edited screenshots can be un-redacted.
