Security breaches discovered in 23 file conversion apps – iPhone Italy

Cyber ​​security firm Wandera has found that over 20 file conversion applications on iOS are not encrypted, putting users’ shared documents at risk.

unencrypted apps

The 23 applications reported from Wandera are used by over 3 million users all over the world and have been developed by a single software house, Cometdocs. These apps are for convert documents into different formats, such as Word to PDF or PDF to PowerPoint

The problem is that the conversion process is managed by a Cometdocs server, with the original documents that they are sent without any form of encryption.

The apps also allow you to access the most popular file hosting services, including Gmail, iCloud, DropBox, Google Drive, OneDrive or Box, to recover all the files stored by the user. Alternatively, the user can choose to directly upload a file from his device.

Since all the files are transferred to the company’s servers without any protection, however, there are potential risks for users. An attacker could easily access these files while sniffing traffic on the same Wi-Fi network.

Wandera has contacted the developer three times in the past three months but has not received a response.
