Powerful DDoS Attack Sets New Record at 1.7 Tbps

Last week's i.3 Terabits per 2nd DDoS attack on Github is no longer the biggest on record.

On Monday, a mysterious party launched a 1.seven Tbps DDoS assail, according to the security provider Arbor Networks. The assault was directed at an unnamed "United states of america-based service provider," which survived the sudden flood of internet traffic without disruption, Arbor Networks said.

Who was behind the set on isn't known. But the incident exploited the same attack method that struck Github concluding week. In both cases, the perpetrators amplified their DDoS attacks with online data storing systems called "memcache servers."

These servers are designed to speed upwards websites and internet services. However, they can as well be used to magnify data packets past up to 51,000 times. When weaponized in a DDoS attack, the overwhelming amount of net traffic tin can have down websites.

Making matters worse is that anyone with some technical cognition can take advantage of these memcache servers. An estimated 100,000 have been establish publicly running on the net.

"These attacks scare internet service providers the most," said Dale Drew, master security strategist at internet backbone provider CenturyLink. "There are very few DDoS protection providers, deject providers with the capacity to scrub these kind of attacks."

In some expert news, security customs has non yet witnessed an explosion of hackers exploiting memcache servers. According to Drew, recent attacks could exist the work of only i bad player. They probably leveraged between 6,000 to 8,000 memcache servers to deliver the 1.3 Tbps attack on Github final calendar week, he said.

"We aren't sure why he doesn't use more," Drew said. "If that's all he can handle, or if he's trying to randomize the servers, and hide his activity. But nosotros're seeing about 6,000 servers used at whatever given bespeak."

CenturyLink is working with the security community to firewall and patch the vulnerable memcache servers. Thus far, they've pulled 30 to 40 percent of all memcache servers off the public net, leaving about 60,000 online, he said.

ISPs tin suppress the attacks by filtering out the hacker's attempts to communicate with the memcache servers over their networks. CenturyLink and others have been starting to practice this by blocking the specific commands that can trigger a memcache server to amplify a DDoS attack.

"I'm hoping to become this threat addressed inside several days," Drew said. "The bad guy volition and then take no choice but to go for the next low-hanging fruit."

Concluding week's assault on Github also included a ransom note inside that demanded the website pay $xviii,000 in a digital currency called Monero. Yet, the 1.7 Tbps attack on the Us service provider contained no message, according to Arbor Networks.
