A glitch in the code of WhatsApp could let hackers alter your messages and change the words you have sent, cybersecurity researchers have found.
Attackers using the flaw could alter text from quoted messages and manipulate the thread of a conversation, experts claim.
They could even make it look as if the sender said something they didn't say, by putting a different name above the comments made.
Israeli-based cybersecurity firm Check Point Research (CPR), who uncovered the flaw, warned that 'malicious actors' may use the glitch to spread misinformation and fake news.
Their team detailed the hack at the Black Hat cyber-security conference in Las Vegas, attended by other experts who also uncover vulnerabilities in popular software.
