Experts Warn of Privacy Risks Caused by Link Previews in Messaging Apps

October 26, 2020Ravie Lakshmanan
Cybersecurity researchers over the weekend disclosed new security risks associated with link previews in popular messaging apps that cause the services to leak IP addresses, expose links sent via end-to-end encrypted chats, and even unnecessarily download gigabytes of data stealthily in the background. "Links shared in chats may contain private information intended only for the recipients," researchers Talal Haj Bakry and Tommy Mysk  said . "This could be bills, contracts, medical records, or anything that may be confidential." "Apps that rely on servers to generate link previews may be violating the privacy of their users by sending links shared in a private chat to their servers." Generating Link Previews at the Sender/Receiver Side Link previews are a common feature in most chat apps, making it easy to display a visual preview and a brief description of the shared link.

Atlassian's group chat platform HipChat is notifying its users of a data breach after some unknown hacker or group of hackers broke into one of its servers over the weekend and stole a significant amount of data, including group chat logs.

Last year, Iran blocked Telegram and many other social networks after their founders refused to help Iranian authorities to spy on their citizens. Now it looks like Iranian government wants tighter controls on all foreign messaging and social media apps operating in the country that will give the authorities a wider ability to monitor and censor its people. All foreign messaging and social media apps operating in Iran have one year to move 'data and activity' associated with Iranian citizens onto servers in Iran, Reuters reported . In order to comply with the new regulations, the companies would need to set up data centers in Iran within one year, but apps may lose a larger number of users by moving data onto Iranian servers. However, transferring data to Iran servers might not be enough, as some of the most popular messaging services like WhatsApp , Apple iMessage , and Telegram are offering end-to-end encrypted communication i.e. nobody in between, not even Whats
