Atheists Fall Victim to Cyber Attack


Months before the Global Atheists Convention is held in Melbourne this March, a couple of major atheist Web sites have been forced to shut down due to coordinated, denial-of-service attacks. The Sydney Morning Herald reports that the Atheist Foundation of Australia (AFA) and the Global Atheist Convention both had their sites paralyzed by the attack, which overloaded both sites with traffic. At that point, the Global Atheists Convention had already sold over 1,000 tickets, with the AFA hailing it as the largest gathering of atheists in Australian history. Yesterday's attack, though, put a sudden stop to the sales, and, as of Thursday morning, both sites had still not yet regained full consciousness.

Speculation Runs Wild Over Motive for Twitter Attack

Last week's Twitter outage really put a damper on our traditional work routine, which involves wasting copious amounts of time sending and receiving 140-character morsels of information and pseudo-human contact. Some of us took the opportunity to rediscover the joys of being a productive member of society, while others, like TechCrunch's Michael Arrington, just decided to continuously update their blogs with what would otherwise have been tweets.

Once the panic passed and we remembered we had friends IRL (in real life) we should probably be talking to, it was time to ask the more important questions: how, and why, did this happen?

The specifics are still being ironed out, but what is clear is that Twitter, Facebook, and LiveJournal were victims of a Denial of Service (DoS) attack that overwhelmed their servers.

The much more difficult question, though, is the "why."

Conficker Virus to Attack Southwest Airlines Web Site


Oh that Conficker virus, it just won't go away. Despite its authors having a bounty placed on their heads by Microsoft, the thing is still spreading, updating itself, and becoming even more prevalent. That spells bad news for Southwest Airlines, discovered Mike Wood, a security expert at SophosLabs. In a recent SophosLabs corporate blog post, he explained that millions of computers infected with the virus are set to start accessing, and thus attacking, the Southwest's Web site on March 13.

Have you ever been the victim of a computer virus?



When the infected hoard begins hitting the Southwest.com site, Conficker will have effectively started a distributed denial-of-service attack, or DDoS attack. The intent is to flood the servers hosting that page and bring them offline, so that anyone else who attempts to browse to that site receives only an error message.

Assuming the attack takes place, it shouldn't impact the overall ability of the airline to launch flights and handle passengers, but online check-in will almost surely be unavailable, as well as any other functionality the airline provides online. So, plan ahead, because you might need to get to the airport a little earlier than you'd like! [From: CNET News]

Online Attacks Getting Bigger, Stronger, Says Report


Cyber criminals have proven again and again that they're a step or two ahead of the law enforcement and computer techs that are trying to stop them, but a new report says criminals aren't restraining themselves to viruses and shady emails. The survey shows that distributed denial of service, or DDOS, attacks are increasing in number and potency and could threaten the largest Web sites and networks. DDOS attacks use botnets, a string of infected computers, to overload and crash servers, and they have been used in political and military conflicts, as well as garden-variety Internet schemes.

Arbor Networks, a network security company, conducted a survey of 70 of the largest service providers in the world, and Arbor says that the size of attacks has increased over the last seven years from less than half a megabit to 40 gigabits. According to Arbor, most businesses have one gigabit connections or less, so even a relatively small DDOS attack can bring them down. Companies are responding by adding capacity to their networks, but it's still plausible that a large attack will succeed.

Another eye-opener in the report is that 58-percent of the surveyed operators hadn't referred any attacks to law enforcement in the last year. The reasons? Some said the law isn't equipped to deal with it, others thought customers should be the ones reporting it, and still others just didn't see the point. And they wonder why criminals consistently have the upper hand? [Source: New York Times]

Hackers Take Out Scientology Web Site


Well, it looks like the war is on. The Church of Scientology's attempts to squash circulation of a video of Tom Cruise last week seem to have been the final straw for a group that calls itself "Anonymous." According to a recent report in Wired, the cryptically-named organization recently stated that its main goal is to destroy the leadership of the Church of Scientology.

The first public salvo was launched over the past couple of days as a group of hackers claiming affiliation with Anonymous took down the home page of the Church with repeated distributed denial of service (DDOS) attacks. DDOS attacks flood target servers with requests, so that they become overwhelmed with data and shut down. This results in a site that doesn't work, which is exactly what visitors to the Scienology Web site experienced during the attack. The attacks flooded Scientology's Web servers with as much as 220 megabits per-second, which security experts claim is a mid-sized attack.

While this attack is not the largest of its kind ever seen, it does show some level of organization, "It's not just one or two guys hanging out in the university dorms doing this," said Jose Nazario, a senior security engineer with Arbor Networks. The church has since moved its site to servers run by Prolexic Technologies, a company that specialized in protection from DDOS attacks.
