Facebook Inc’s WhatsApp messenger service said on Wednesday it has fixed the latest bug on its platform that allowed hackers to take over users’ applications when they answered an incoming video call, Reuters reported.
The vulnerability, which affected WhatsApp applications on Apple and Google Android smartphones, was discovered in late August and was fixed by Facebook in early October.
“We routinely engage with security researchers from around the world to ensure WhatsApp remains safe and reliable. We promptly issued a fix to the latest version of WhatsApp to resolve this issue,” WhatsApp said.
WhatsApp is used by more than 1.2 billion people around the world and is a key tool for communications and commerce in many countries. The service was acquired by Facebook in 2014 for $19 billion.
Facebook has suffered a string of security-related problems in the last year. The US-based social media company last week disclosed its worst-ever security breach affecting nearly 50 million accounts.
