WhatsApp’s security teams have identified and blocked a cluster of malicious activities originating from Iran.
The targeted campaign, linked to the Iranian threat actor group APT42, focused on political and diplomatic officials across several countries, including Israel, Palestine, Iran, the United States, and the UK.
This article delves into the details of the attack, the group behind it, and the measures taken to counteract these threats.
APT42: The Persistent Threat
APT42, also known as UNC788 and Mint Sandstorm, is notorious for its persistent adversarial campaigns.
Known for employing basic phishing tactics, this group has been stealing credentials from online accounts across the internet, as per a report by Meta.
Their targets have included Saudi military personnel, dissidents, human rights activists from Israel and Iran, US politicians, and Iran-focused academics and journalists globally.
The recent WhatsApp campaign saw hackers pose as technical support for major tech companies like AOL, Google, Yahoo, and Microsoft, attempting to deceive high-profile individuals into revealing sensitive information.

Unsuccessful Attempts and User Vigilance
WhatsApp users’ vigilance played a crucial role in thwarting this latest attack. Many individuals targeted by APT42 reported suspicious messages using WhatsApp’s in-app reporting tools.
This proactive approach enabled WhatsApp’s security teams to investigate and link the activity to APT42, ultimately preventing any account compromises.
Encouraged by this success, WhatsApp has urged users to continue reporting suspicious activities and to take steps to secure their online accounts.
The company has also shared information about the malicious activity with law enforcement and presidential campaigns in the US, emphasizing the need for heightened caution before the upcoming election.
Ongoing Monitoring and Security Measures
WhatsApp remains committed to monitoring and disrupting malicious activities on its platform. The company collaborates with industry peers, such as Microsoft and Google, to stay informed about potential threats.
When cyber espionage actors are detected, WhatsApp takes decisive action, including deleting their accounts, blocking the sharing of their domains, and notifying targeted individuals.
Public figures, journalists, political candidates, and campaigns must remain vigilant, utilize privacy and security settings, and avoid engaging with unknown contacts.
As cyber threats evolve, the importance of cybersecurity awareness and proactive measures cannot be overstated.
WhatsApp’s efforts to disrupt these operations serve as a reminder of the ongoing battle against cyber espionage and the need for collective vigilance in safeguarding digital communications.
