New Net Reality: Hijacked Web, Deluge of Data Bringing Down Entire Corporate Networks

November 10, 2008

Attackers bent on shutting down large Web sites — even the operators that run the backbone of the Internet — are arming themselves with what are effectively vast digital fire hoses capable of overwhelming the world’s largest networks, according to a new report on online security.

In these attacks, computer networks are hijacked to form so-called botnets that spray random packets of data in huge streams over the Internet. The deluge of data are meant to bring down Web sites and entire corporate networks. Known as distributed denial of service, or DDOS, attacks, such cyberweapons are now routinely used during political and military conflicts, as in Estonia in 2007 during a political fight with Russia, and in the Georgian-Russian war last summer. Such attacks are also being used in blackmail schemes and political conflicts, as well as for general malicious mischief.

A survey of 70 of the largest Internet operators in North America, South America, Europe and Asia found that malicious attacks were rising sharply and that the individual attacks were growing more powerful and sophisticated, according to the Worldwide Infrastructure Security Report. This report is produced annually by Arbor Networks, a company in Lexington, Massachusetts, that provides tools for monitoring the performance of networks.

The report, which will be released Tuesday, shows that the largest attacks have grown steadily in size to over 40 gigabits, from less than half a megabit, over the last seven years. The largest network connections generally available today carry 10 gigabits of data, meaning that they can be overwhelmed by the most powerful attackers.

The Arbor Networks researchers said a 40-gigabit attack took place this year when two rival criminal cybergangs began quarreling over control of an online Ponzi scheme. “This was, initially, criminal-on-criminal crime though obviously the greatest damage was inflicted on the infrastructure used by the criminals,” the network operator wrote in a note on the attack.

Tibetans Protest & China Awaits Olympic Torch

March 30, 2008

NEW DELHI (AFP) – Several dozen Tibetans in India on Sunday unveiled an “independence torch” in New Delhi that will be carried around the world in an anti-China protest ahead of the Summer Olympics in Beijing.

The torch was brought from the northern Indian town of Dharamshala — home to the Dalai Lama, the Tibetan spiritual leader, and the government-in-exile.

The next stop for the protest flame is San Francisco, where the real Olympic torch is expected on April 9.

“This relay is to protest Chinese rule in Tibet. We also don’t want the Olympic torch to go to Tibet because it is not a part of China,” said Urgyen Chophel, president of the Tibetan Youth Congress.

China has come under increasing international pressure over its crackdown against protesters in the Tibetan capital Lhasa and Chinese provinces bordering the Himalayan region.

Tibetan activist groups have put the death toll from weeks of unrest at 135-140 Tibetans. China says rioters killed 18 civilians and two police officers.

Protesters disrupted the Olympic torch-lighting ceremony in Greece last Monday.

China awaits Olympic torch amid Tibet tensions

By Dan Martin Sun

BEIJING, March 30, 2008 (AFP) – China on Sunday stepped up security on the eve of the arrival of the Olympic torch from Greece, where protesters angry over Beijing‘s crackdown in Tibet tried to disrupt the handover of the flame.

Authorities in Beijing clamped down on Tiananmen Square, where the torch will be officially welcomed to the country on Monday before a worldwide relay expected to be dogged by protests over the deadly unrest in Tibet.

Tensions continued to simmer in the Himalayan region, with activist groups reporting a fresh protest in Lhasa at the weekend, while in neighbouring Nepal, police baton-charged Tibetan protesters Sunday, detaining more than 100 people.

In Athens, Greek officials handed the Olympic flame to the head of the Beijing organising committee, Liu Qi, after police arrested a handful of protesters shouting “Free Tibet”.
