WhatsApp Security Incident – Here’s What to Do

WhatsApp disclosed a serious security vulnerability with which hackers could install malware. It was discovered that the messaging app WhatsApp contained spyware that can be used to gain access to any device it was installed on. The hack was reported to US officials and the European Union’s lead privacy regulator, Ireland’s Data Protection Commissioner (DPC).

The vulnerability allows hackers to inject spyware when WhatsApp users made or received voice calls. WhatsApp’s security advisory on Facebook stated, “A buffer overflow vulnerability in WhatsApp VOIP stack allowed remote code execution via specially crafted series of SRTCP packets sent to a target phone number.”

The WhatsApp security vulnerability allowed hackers to install spyware which can be used to take control of the phone including the camera. The malware, in this case spyware, took advantage of a vulnerability during missed calls in the app’s voice calling function. The malware allowed hackers to gain access to personal data on hacked phones.

“The DPC understands that the vulnerability may have enabled a malicious actor to install unauthorized software and gain access to personal data on devices which have WhatsApp installed,” the EU regulator stated.

So far, WhatsApp has not notified the DPC of the matter under GDPR Article 33, Notification of a personal data breach to a data protection supervisory authority. It is not known yet is any EU citizens’ data was affected by the cyber security incident. “WhatsApp is still investigating as to whether any WhatsApp EU user data has been affected as a result of this incident,” the DPC said, adding that WhatsApp informed it of the incident late on Monday.

Who is the NSO Group?

It is suspected that the spyware is the work of Israel’s NSO Group. WhatsApp has not confirmed the identification of the hackers. The spyware takes advantage of vulnerabilities to hack smartphones. Once access is acquired, the spyware can control the phone’s camera and be used to surveil the device’s owner. NSO malware has been used to spy on journalists, lawyers, human rights activists, and dissidents in previous hacks. NSO spyware was implicated in the death of Saudi journalist Jamal Khashoggi.
