Signal [1] [2] [3] [4] [5] [6] [7], a popular messaging app known for its strong encryption and focus on user privacy and data security [7], has addressed rumors circulating on social networks regarding a zero-day vulnerability. This improved text aims to present the information in a more coherent and authoritative manner.


Signal conducted a thorough investigation into the rumors, which originated from social media accounts but lacked evidence or documentation [1]. The platform found no evidence to support these claims and reached out to USCYBERCOM for further information. The agency confirmed that they hold no such information. Signal’s president explicitly refuted the reports and emphasized that there is no evidence of a bug. The user who initially posted about the vulnerability later apologized and admitted that the information was false [7].

Despite this [7], some Signal users have deactivated the feature in question as a precaution [7]. Signal encourages anyone with relevant information to come forward [4], as they are still interested in any evidence of the vulnerability [4]. If the flaw does exist, Signal is eager to receive details so that it can be patched. It is important to note that there is currently no concrete evidence to support the reports of a zero-day vulnerability in Signal [7].

However, security researcher Matt Blaze suggested that the rumors may refer to a known vulnerability involving an open-source image library [1], which Signal has already addressed with a patch. Signal also emphasizes the importance of practicing safe computing, ensuring privacy settings are correctly configured [3], and regularly updating apps. Some security experts advise users to disable unnecessary features [1], such as link previews [1], to enhance safety on the app [1].


In conclusion, Signal has thoroughly investigated the rumors of a zero-day vulnerability and found no evidence to substantiate them. The platform remains open to receiving any evidence of the vulnerability and encourages users to come forward. While there is currently no concrete evidence of a zero-day vulnerability [7], Signal has already addressed a known vulnerability involving an open-source image library [1]. It is crucial for users to practice safe computing and keep their apps updated to ensure data security and privacy.
