A massive cyber attack targeting a European spam-fighting group that slowed some global Internet traffic to a crawl appears to have been launched by a gang of hackers from Russia and neighboring countries, says the head of a Russian firm specializing in defending against such attacks.

MOSCOW–A massive cyber attack targeting a European spam-fighting group that slowed some global Internet traffic to a crawl appears to have been launched by a gang of hackers from Russia and neighboring countries, says the head of a Russian firm specializing in defending against such attacks.

Alexander Lyamin, of Moscow’s Highload Labs, says he believes the same group who have caused trouble around the world with their attack against the non-profit Spamhaus Project Ltd. had earlier launched a series of brief strikes on several top Russian Internet companies as a trial run of their weapon known as a Domain Name System amplification attack.

“We first noticed incidents utilizing this technique a month-and-a-half ago in Russia. It started with a measly 10-20 gigabytes per second, but during the next month it grew to 60 and then 120 gigabytes. Apparently the attackers were growing their network of hacked servers,” Mr. Lyamin said.

The attacks against Spamhaus began on March 19 and appeared to have subsided on Wednesday. Some experts said the attack grew to as large as 300 gigabytes per second, which would make it the largest ever seen, although others–including Mr. Lyamin — dispute that.

A DNS amplification attack works by manipulating the basic system by which the Internet operates wherein a series of domain name system servers convert searches for particular sites, like www.wsj.com, to their INS address which is actually a numerical code and makes the connection. The attack utilizes a network of hacked DNS servers to answer fake messages that appear to come from a targeted site with much larger responses. While this cripples the target site, it also severely slows the DNS server which results in bogging down scores of other searches. In the Spamhaus attack, experts have said they believe millions of web surfers were affected.

Spamhaus has accused Dutch Web-hosting company Cyberbunker for being behind the attack in a tit-for-tat retaliation for Spamhaus putting Cyberbunker on a blacklist for allegedly allowing vast amounts of spam to be sent through its servers.

Spokespeople for Cyberbunker and Spamhaus did not immediately respond to messages seeking comment. In a statement on its Website, Spamhaus said “a number of people have claimed to be involved in these attacks. At this moment it is not possible for us to say whether they are really involved.”

While Mr. Lyamin would not name the Russian companies that were the earlier targets because of “the very sensitive nature of this matter,” but said they included services used by Russians every single day.

“The targets were companies with good visibility and big names, but the attacks were only for a short duration of time. We think it was done for bragging rights. Also lots of Internet trash was targeted–porn, scam, drugs, piracy, etc. It was like a child playing Robin Hood or something,” he added.

He said the targeting of Russian companies, and the fact that the attacks tended to begin during daylight hours in Russia’s timezone, led his team to believe the attacks were launched by “a group of Russians or from our closest neighbors.”

Mr. Lyamin says he suspects whoever was behind the spam that Spamhaus had targeted had hired the hackers to launch the attack, which he said is a copycat of one undertaken in October 2010, about 20% smaller by volume of traffic.

“This is not new,” he said. “And I really doubt this is the biggest.”

Mortar attacks on Damascus University killed at least 15 students as fighting in the capital spread to the airport.

The students were killed on Thursday when rebel mortar bombs landed on the canteen of Damascus University’s College of Architecture, two pro-government television channels said.

One station, Ikhbariya, showed images of doctors pumping the chests of at least two young men and blood splattered on the floor of what appeared to be an outdoor canteen.

A young women was shown walking in a hospital and bleeding heavily from her face.

The college is in Baramkeh, a central Damascus suburb where mortar attacks by rebels fighting to oust President Bashar al-Assad have intensified this week.

The university is surrounded by government buildings, including the Ministry of Defence, the headquarters for state media and the president’s official residence.

 

Once a bastion for Assad’s forces, the capital has become a focal point of the two-year-old uprising against four decades of family rule that has developed into civil war in which more than 70,000 people have been killed.

Rebels have formed a semi-circle around the capital and are trying to gain control of strategic areas to help them break into the centre of Damascus.

State television blamed rebels who have stepped up attacks in the heart of the Syrian capital.

“The number of students killed in the mortar attack on the architecture faculty in Damascus University has risen to 12,” said the broadcaster. “The National Students Union condemns the cowardly terrorist attack that targeted the architecture faculty of Damascus University.”

SANA, the state newsagency, added that six others were hurt by “mortars that targeted the faculty cafeteria”.

Rebels fighting to oust President Bashar al-Assad have this week escalated their mortar attacks on central Damascus, including Umayyad Square in the middle of the capital, which houses the state television headquarters. The Syrian Observatory for Human Rights, a Britain-based monitoring group that relies on sources on the ground for its information, also reported Thursday’s attack, although it put the toll at 10 people dead.

The United Nations refugee agency voiced deep concern on Thursday at reports of mass deportations of Syrians from Turkey and said it had taken up the issue with Turkish authorities.

Turkish officials said that Turkey sent hundreds of refugees back to Syria after clashes with military police at their camp near the border in a protest over living conditions, although the foreign ministry later said 50-60 Syrians had returned voluntarily.

“UNHCR is very concerned with reports of a serious incident and allegations of possible deportations from Akcakale Tent City in the past 24 hours,” Melissa Fleming, chief spokeswoman of the U.N. High Commissioner for Refugees (UNHCR), said.
