World biggest DDoS attack that almost broke Internet


The last week has seen probably the largest distributed denial-of-service (DDoS) attack ever. A massive 300Gbps was thrown against Internet blacklist maintainer Spamhaus' website but the anti-spam organisation , CloudFlare was able to recover from the attack and get its core services back up and running. 

biggest DDoS attack that Almost Broke the InternetSpamhaus, a group based in both London and Geneva, is a non-profit organisation that aims to help email providers filter out spam and other unwanted content. Spamhaus is pretty resilient, as its own network is distributed across many countries, but the attack was still enough to knock its site offline on March 18.

Five national cyber-police-forces are investigating the attacks.  A group calling itself STOPhaus, an alliance of hactivists and cyber criminals is believed to responsible for bombarding Spamhaus with up to 300Gbps.


The attacks on Spamhaus illustrate a larger problem with the vulnerability of systems fundamental to the architecture of the Internet, the Domain Name Servers (DNS). The high attack bandwidth is made possible because attackers are using misconfigured domain-name service (DNS) servers known as open recursive resolvers or open recursors to amplify a much smaller attack into a larger data flood.

DDoS attack

Known as DNS reflection, the technique uses requests for a relatively large zone file that appear to be sent from the intended victim's network. According to CloudFlare, it initially recorded over 30,000 DNS resolvers that were tricked into participating in the attack. There are as many as 25 million of these open recursive resolvers at the disposal of attackers

"In the Spamhaus case, the attacker was sending requests for the DNS zone file for ripe.net to open DNS resolvers. The attacker spoofed the CloudFlare IPs we'd issued for Spamhaus as the source in their DNS requests. The open resolvers responded with DNS zone file, generating collectively approximately 75Gbps of attack traffic. The requests were likely approximately 36 bytes long (e.g. dig ANY ripe.net @X.X.X.X +edns=0 +bufsize=4096, where X.X.X.X is replaced with the IP address of an open DNS resolver) and the response was approximately 3,000 bytes, translating to a 100x amplification factor."

It now seems that the attack is being orchestrated by a Dutch hosting company called CyberBunker. As long as it's not child porn and anything related to terrorism, CyberBunker will host it, including sending spam.  Spamhaus blacklisted CyberBunker earlier in the month.

However, the DDoS attacks have raised concerns that further escalations of the retaliatory attacks could affect banking and email systems. DDoS attacks are typically carried out to extort money from targeted organisations or as a weapon to disrupt organisations or companies in pursuit of ideological, political or personal interests.

Five Most Notorious Hacking Groups Of All Time

The Hackers and the hacking groups are back in lime light with recent attacks over the playstation and different websites. The hackers were very famous in 80s and 90s but their fame faded during Y2k days. So as the hacking groups are on a rise now so here we list some of the most notorious hacking groups of all time.

Masters Of Deception (MOD)

This group was famous for their operations related to the credit cards. This group hacked into the system and stole the credit card history of stars like Julia Roberts and as well as hacked the AT&T’s system for stealing the credit card numbers . The founders of this group were Acid Phreak, Scorpion and HAC and it was a New York based group. MOD was the archrival of Legion of Doom and made a mockery out of it. It said that LOD has lost its direction which resulted in the shifting of the famous hacker Mark Abene (a.k.a Phiber Optik) from LOD to MOD. The days of MOD got over when the FBI and the Secret service arrested the members and locked them behind bars.



Legion of Doom (LOD)

LOD was the biggest enemy of the Masters of Deception (MOD) and one of the most notorious groups of all time. The founder of this group was Lex Luthor (Real Name: Vincent Louis Gelormine) . This group used to publish different journals which used to contain hacking knowledge and information and also used to hack major government related websites.In 1990-1991 this group fought a net based war ,which used Internet,X.25 and the telephone networks, with the MOD which is so famous that the war is known as The Great Hacker War. LOD launched a program which assisted the corporations which were the prey of the Masters of deception. And in the end The great war ended with the loss of LOD and the victory of Masters of Deception.



Milw0rm

Milw0rm shot to fame in the year 1998 when they hacked into the systems of Bhabha Atomic Research Center (BARC) which is the main nuclear center in India. They stole the recent experiment reports and emails and also destroyed 2 of 8 servers. This brought a lot of coverage to the group. The fascinating thing about this group was that it was a teenage group with the youngest member being only 15 years old. After the attack on BARC the group managed successful attacks on the sites of World Cup, Wimbledon, Hotel Ritz , Saudi Royal Family and Drew Barrymore.


Anonymous

This is not technically a hacker group but this group has originated on 4chan boards. This group is one of the most feared groups today. This has the reputation of hacking into the Sony’s Playstation network. The name given to this hacking was #opsony which was a part of the Operation Payback. The motive behind the attack was to bring down the lawsuit that was on a group called Geohot which cracked the PS3 and posted it in Youtube . Apart from this attack, the group is also held responsible for the attacks on the Church of Scientology websites, HB Gary Federal and Westbro Baptist Church. The group s still going strong and some of the major companies are on the edge of their seats thinking who’s next….




Red Hacker Alliance


This is supposedly the largest hacking group in the world as the members are about 80,000. The group was formed when the group started to oppose the ethnic riots in Jakarta, Indonesia. This group used to operate with the name China Redhackers, thus forming a new breed of hackers known as the RedHackers. This group is basically Chinese and is held responsible for the attacks on the CNN website in 2008 . This group has a very huge base and has over 250 websites linked to it. Recently another hacking group named Honker Union has joined hands with this group making it even more stronger.



So these are some of the most notorious hacking groups of all time.
But remember Hacking is real fun only if you are a hacker.
