Rangoon, Burma. A massive cyber attack has crippled Internet services in Burma ahead of Sunday’s election, IT experts and Web service providers say, raising fears of a communications blackout for the vote.
Internet users in the military-ruled country have reported slow connections and sporadic outages for more than a week, and some suspect the junta may be intentionally disrupting services to block news flowing out.
Web service providers have blamed the troubles on outside attacks.
“Our technicians have been trying to prevent cyber attacks from other countries,” a technician from Yatanarpon Teleport said on condition of anonymity.
“We still do not know whether access will be good on the election day,” he added.
A technician from private web provider RedLink Communications said there was still intermittent loss of Internet connection.
“The technicians are trying to fix it … but we cannot tell exactly when it will be back to full service,” he said. “We don’t know the source of the attack yet.”
Experts say Burma’s Internet system has been overwhelmed by a flood of incoming messages known as a Distributed Denial of Service (DDoS) attack.
US-based IT security firm Arbor Networks says the main state-owned Internet provider Myanmar Post and Telecommunications “suffered a large, sustained DDoS attack disrupting most network traffic in and out of the country.”
The onslaught was “several hundred times” more than enough to overwhelm the country’s terrestrial and satellite links, it estimated.
The motives for the attack were unclear, but “large-scale geo-politically motivated attacks — especially ones targeting an entire country — remain rare,” Arbor Networks chief scientist Craig Labovitz wrote in a blog posting.
Some Internet users believe the authorities are intentionally slowing services ahead of Sunday’s vote, the first in 20 years in Burma.
“Although they said the connection has been attacked, it’s hard to believe. I think they have been doing it intentionally for the election day to delay news reaching the international community,” said Kyaw Kyaw, a 25-year-old university student in the main city Rangoon.
The polls have been widely criticized by pro-democracy activists and Western governments as being aimed simply at prolonging military rule under a civilian guise.
Foreign journalists and election monitors are not being allowed into the country for the election.
During monk-led protests in 2007, Burma’s citizens used the web to leak extensive accounts and video to the outside world, prompting the regime to block Internet access.
Connections have also been slowed down on politically significant dates, such as the Aug. 8 anniversary of a mass political uprising in 1988.
In September of this year, the Web sites of Burma exile media organizations were temporarily crippled by DDoS attacks on the third anniversary of a crackdown on the “Saffron Revolution” monk-led protests.
Even in normal circumstances, the Web’s reach outside the major cities of Rangoon and Mandalay is severely limited.
Just one in every 455 of Burma’s inhabitants were Internet users in 2009, based on statistics from the International Telecommunication Union, a UN agency in Geneva.
Media watchdog Reporters Without Borders describes Burma’s legislation on Internet use, the Electronic Act, as “one of the most liberticidal laws in the world”, with online dissidents facing lengthy prison terms.
