Back in 1999, the government launched DoS attacks against foreign websites associated with Falun Gong, a spiritual movement banned in China.

Both carriers are vulnerable to a "voice DoS," shutting down a conversation mid-call with a flood of signal bearers.

DoS attacks over Tor are easier to perpetrate than on the “clearweb”, largely because there just isn’t the same level of bandwidth on Tor.

Arbor Networks, a private firm that tracks cybersecurity threats, said that in just the past day, France has suffered over 1,070 DoS problems with its websites, The Associated Press reports.

From the logs, some have suggested that the DoS attack, as detailed above, was responsible for "de-anonymising" users of the site.
