2007 cyberattacks on Estonia

Cyberattacks on Estonia were a series of cyber attacks that began 27 April 2007 and swamped websites of Estonian organizations, including Estonian parliament, banks, ministries, newspapers and broadcasters, amid the country's disagreement with Russia about the relocation of the Bronze Soldier of Tallinn, an elaborate Soviet-era grave marker, as well as war graves in Tallinn. Most of the attacks that had any influence on the general public were distributed denial of service type attacks ranging from single individuals using various methods like ping floods to expensive rentals of botnets usually used for spam distribution. Spamming of bigger news portals commentaries and defacements including that of the Estonian Reform Party website also occurred.

Some observers reckoned that the onslaught on Estonia was of a sophistication not seen before. The case is studied intensively by many countries and military planners as, at the time it occurred, it may have been the second-largest instance of state-sponsored cyberwarfare, following Titan Rain.

Estonian Foreign Minister Urmas Paet accused the Kremlin of direct involvement in the cyberattacks. On 6 September 2007 Estonia's defense minister admitted he had no evidence linking cyber attacks to Russian authorities. "Of course, at the moment, I cannot state for certain that the cyber attacks were managed by the Kremlin, or other Russian government agencies," Jaak Aaviksoo said in interview on Estonian's Kanal 2 TV channel. Aaviksoo compared the cyber attacks with the blockade of Estonia's Embassy in Moscow. "Again, it is not possible to say without doubt that orders (for the blockade) came from the Kremlin, or that, indeed, a wish was expressed for such a thing there," said Aaviksoo. Russia called accusations of its involvement "unfounded," and neither NATO nor European Commission experts were able to find any proof of official Russian government participation.
