A newly-discovered email loophole could allow for widespread snooping of other people's online messages, adding to concerns over Internet privacy.
That means, for example, that someone could send a message to a colleague, and if the message is forwarded to others, each forwarded message or reply would be copied and sent to the original sender, according to the Privacy Foundation.
The group believes spying on others' conversations could become common using this loophole. "Most of us won't release a computer virus, but this is something people would use, particularly if a service started offering it," chief technology officer Richard M Smith told the New York Times. "It's just kind of human nature."
The Privacy Foundation plans to publicise its discovery Monday.
