Cyber criminals could use this trick to ‘crack into YOUR private messages’
Urgent warning issued over 'vulnerability' which allegedly allows crooks to carry out devastating fraud campaigns
Cyber sleuths have discovered a scary Facebook security flaw which allegedly allows "malicious" hackers to carry out super-sophisticated fraud campaigns.
Experts from a security firm called Check Point said the vulnerability would let crooks hack into private messages and even change the contents.
This could allow them fraudsters to "change the history of a conversation to claim he had reached a falsified agreement with the victim", researchers claimed.
The firm wrote: "The vulnerability allows a malicious user to change a conversation thread in the Facebook Online Chat and Messenger App.
"By abusing this vulnerability, it is possible to modify or remove any sent message, photo, file, link, and much more."
It could even let crims "hide evidence of a crime or even incriminate an innocent person".
Facebook also said the falsified messages "self corrected", and snapped back to their original form.
It denied that viruses could be sent using messaging services.
"We appreciate the researchers who reported it and helped us create a better experience for all the people who use Messenger," Facebook added.
