Victor added, “To date, most of the malicious software has focused on intercepting archived WhatsApp messages and online dialogues, and that we haven’t yet encountered any interception of calls, including group calls. Nevertheless, if a tool is infected, it’s highly likely that the Trojan will have the power to record the device microphone and camera – enabling attackers to pay attention to any conversations, no matter the channel used, be it a moment messenger or a daily turn a mobile .”
WhatsApp has also created a call information screen so that users can see who is already on the call and who has been invited but not yet joined.
And if users tap ‘Ignore’, WhatsApp can be added later from the Calls tab.
