The Electronic Frontier Foundation (EFF) revealed on Wednesday that employees of Internet freedom NGOs “Free Press” and “Fight for the Future” have been targeted in sophisticated spear-phishing attacks.

The EFF is aware of nearly 70 attempts to steal the credentials of net neutrality activists between July 7 and August 8. The attacks, believed to be the work of a single entity, were designed to steal credentials associated with Google, Dropbox, LinkedIn and other online services.
