WhatsApp's new 'guest chats' function raises concerns among UAE cybersecurity specialists about potential identity theft issues.
WhatsApp, the popular messaging app, is developing a new feature called 'Guest Chats'. This feature will allow users to chat with non-WhatsApp account holders, according to WABetaInfo, a website that regularly reports on WhatsApp news and updates.
However, the 'Guest Chats' feature is currently in its development phase and has not yet reached the beta phase. This new feature raises concerns about potential cybersecurity risks, as expressed by Haider Pasha, chief security officer at Palo Alto Networks EMEA.
In 'Guest Chats', the recipient does not register inside WhatsApp, but their identity is confirmed through the channel the link is sent to. The sender in 'Guest Chats' is a verified WhatsApp account that generates and shares a link. If the sender's number or profile is hidden, the recipient cannot confirm who's contacting them, which could potentially lead to increased risks.
Pasha notes that without an account, attackers can easily impersonate others, making trust harder to establish between parties. He advises users to remain vigilant and be extra cautious when connecting with unknown individuals using the 'Guest Chats' feature. Pasha also suggests that attackers could exploit the anonymity feature to launch social engineering attacks or spread malicious links.
To protect oneself after the expected roll out, it is advised to use two-factor authentication, avoid clicking on unfamiliar links, and share personal information cautiously. It is also recommended to restrict profile visibility in WhatsApp, such as allowing only contacts to see the profile photo, status, and last-seen.
Pasha further advises that ideally, WhatsApp should let users revoke or end a guest session at will, just like unlinking a device. This would provide users with more control over their privacy and security.
Meta, the parent company of WhatsApp, has measures in place to combat abuse. They have the sender's WhatsApp account details stored so that abusive users can be reported, investigated, and blocked.
With the new 'Guest Chats' feature, some malicious attackers may increase their attacks, especially those with a WhatsApp account who may distribute fake links in bulk. Users who spread false links and could be potential attackers are those engaging in phishing and social engineering attacks, posing as trusted institutions, companies, authority figures, or acquaintances to deceive victims into revealing sensitive data or clicking on malicious links.
As with any new feature, it is essential to approach 'Guest Chats' with caution and be aware of the potential risks. By following safety measures and staying vigilant, users can enjoy the benefits of the new feature while minimising the associated risks.
