Mozilla permanently shut down its Firefox Send service for transferring files after people used it to launch online attacks, the nonprofit announced Thursday.

« Firefox Send was a promising tool for encrypted file sharing, » Mozilla said in a statement. « Unfortunately, some abusive users were beginning to use Send to ship malware and conduct spear phishing attacks. » Spear phishing is a personalized attack designed to fool you into sharing sensitive information like passwords.

Mozilla a interrompu le service d’envoi pendant l’été lorsqu’il a détecté le problème, puis a décidé que cela ne valait pas la peine de relancer.
