CVE-2014-0050: Apache Tomcat vulnerable to Denial of service attack

If you are a developer, you should always be careful when writing loops especially an endless loops [ for(;;) or while(true) ] which are coded to be stopped by an 'if' statement.

Security researchers from TrustWave have explained how an endless 'for' loop resulted in a denial of service vulnerability that could allow attackers to launch DOS attacks against websites hosted on Apache Tomcat servers.

The vulnerability(CVE-2014-0050) is located in Apache Commons FileUpload file.  The 'for' loop in the file is coded in such a way that it will be stopped by raising an exception or by returning a value. 

An attacker can send a malformed 'Content-type' header for a multipart request which could result in an infinite loop.

Multipart is often used in HTTP request for uploading files.  Values in the multipart requests are separated by a magic line called "boundary".  Boundary is a random string which will be defined in the 'content-type' header.

By sending a boundary value longer than 4091 characters and 'body' longer than 4096 characters, the 'for' loop won't be stopped by both 'if' statement.

TrustWave researchers managed to send four times a request containing more than 4091 characters in the boundary field that forces vulnerable tomcat server into an infinite loop.  As a result, the tomcat server will end up in consuming all available CPU resources until it is stopped.

Anonymous hacktivists launch DDOS attack against GCHQ website

It seems like Anonymous hackers have launched a Distributed denial of service(ddos) attack against GCHQ website.

The attack just came after Edward Snowden leaked a document which revealed that British Spy Agency (GCHQ) carried out ddos attacks to disrupt the anonymous hacktivists' communication channel.

Some anonymous hacktivists also claimed to have successfully disrupted the website of GCHQ.  Netcraft confirmed that today has experienced 'noticeable performance issues'.  Netcraft says the attack could be originated from Romania.

"Curiously, a much larger amount of downtime has been observed from Netcraft's Romanian performance monitor since the leaked slides were made public."Netcraft post reads.

"That could indicate much more extreme DDoS mitigation techniques are being applied to these requests, and this in turn suggests that if an attack is occurring, perhaps Romania is one of the countries from which the attacks are being launched."

400Gbps NTP-based DDOS attack hits CloudFlare - largest DDOS attack in History

Until a week ago, it was believed that Distributed denial-of-service(DDOS) attack against Spamhaus is the largest one in the history.  Now, an even bigger DDOS attack has been recorded by the Content delivery Network CloudFlare.

Matthew Prince, CloudFlare CEO, said in twitter that very big NTP reflection attack was hitting them and appears to be bigger than the Spamhaus attack from last year.

According to Matthew, the attack reached 400Gbps which is 100Gbps higher than the ddos attack targeting Spamhaus. 

CloudFlare said all websites have returned to production.

Founder of a French hosting firm OVH also said their network received more than 350Gbps traffic, but it is not clear whether it is related or not.

Last month, CloudFlare also wrote an article detailing about the Network Time protocol(NTP) based DDOS attacks that caused trouble for some gaming web sites and service providers.

NTP protocol is UDP-based protocol runs on port 123 which is used by Internet connected computers to set clocks accurately.  A system will synchronize with the server and receives the current time.

Experts says this protocol is prone to amplification attacks because it will response to the packets with spoofed source IP address "and because at least one of its built in commands will send a long reply to a short request. That makes it ideal as a DDoS tool."

List of open NTP servers on the Internet allows attackers to launch Denial of attack against any target network. 

Hackers launched DDOS attack against EA Origin Server & Steam server

"The reason for me attacking these games, is because games are bad for the soul (<3 Jesus) my kids were poisned by games." One of the tweets of @LARCENY_ reads.

Another Group called DERPTrolling has taken credits for taking EA's Origin Online gaming service offline that left users unable to login.

"We're working to resolve connectivity/login issues affecting various platforms/games. Thank you for your patience. Updates when available^EX" EA Support account posted a tweet regarding the issue.

NatWest online banking service hit by DDOS attack

A cyber attack to disrupt online banking services of Natwest left the customers unable to access their accounts online.  The website suffered a distributed denial of service(DDOS) attack.

"We have taken the appropriate action to restore the affected web sites.  At no time was there any risk to customers.  We apologise for the inconvenience caused."

This is not the first time the Natwest website under a cyber attack.  Earlier this month, all of RBS and NatWest's systems went down for few hours.

It is still unknown who is responsible for this cyber attack.  Bank customers started to blame the Bank for not able to access their accounts. 

Agency claims down because of "Internal Error"

#OpSaudi : Anonymous launched cyber attack on Saudi Government site

Saudi branch of Anonymous hacktivist has launched cyberattack on Saudi Government websites , the operation has been named as "#OpSaudi". Few government websites are facing heavy Distributed-denial-of-service(DDOS) attack from the Anonymous.

The affected government sites include Saudi Arabia and the Ministry of Foreign Affairs(, The Ministry of Finance(, General Intelligence Presidency( )., Riyadh Region Traffic(, are also being targeted by the hackers.

The Anonymous saudi also claimed they have gained access to the server of Qassim Region Traffic website( and deleted the database. 

General Directorate of Education in Jeddah website fell victim to the cyber attack.  Hackers identified and exploited the SQL Injection vulnerability in

"saudi people like slave for the gov , and 2 days ago a saudi prince kidnapped a girl & raped her . then killed her and throw her body naked" Anonymous Saudi stated as reason for the cyber attack. 

DDOS attack brings the Internet to its knees

The fight between a spam fighting company called "Spamhaus" and a web hosting company called "Cyberbunker" has slowed down a majority of the internet by making DNS resolving slow.

The reason behind the attack is that Spamhaus added the IP addresses of cyberbunker to its "spam" list due to Cyberbunker allowing almost any sort of content to be hosted hence also maybe the source for spam. So Cyberbunker attacked back and this attack also affected normal internet users.

The attack was possible because of the large number of vulnerable DNS servers that allow open DNS resolving.Simply put an attack exploiting this type of vulnerability makes use of the vulnerability of the DNS server to increase the intensity of the attack 100 fold.

The origins of these type of attacks goes back to the 1990's to an attack called "smurf attack"

But now the attack method has become more efficient and uses DNS amplification to flood the victim with spoofed requests which are sent to the DNS servers by using a botnet of compromised computers.The attack at its peak reached a speed of 300 Gbps making it the largest DDOS attack in history.

Cyberbunker which claims itself to be a supporter of free speech and defender against the "big bullies" seems to have now have stooped down to their level of using aggressive offensive methods that affect the normal functioning of the internet.This is not the way to go !

The people who run DNS resolvers are also equally responsible for these attacks as its their vulnerable servers that make these attacks possible, the internet community should come up with a PERMANENT solution to this problem.

New Android malware helps Cybercriminals to launch DDOS attacks

The Russian antivirus firm Doctor Web has discovered a new Android Trojan that helps Cyber criminals to launch Distributed-denial-of-service(DDOS) attacks. It is also capable of sending sms based on the command received from the hacker.

According to the report, the malware "Android.DDoS.1.origin" likely spreads via Social engineering attacks and disguises itself as a legitimate application from Google.

fake google android malware
Fake Google Play icon
After installation, the malware creates an application icon that look like Google Play icon. If a user taps the fake Google play icon, it will still launch the original Google play. But , in background, it starts malicious activity.

Once the malware is launched, it transmits the victim's phone number to cybercriminal and then waits for further SMS instructions.

From now onwards, the Cyber criminal can launch DDOS attack against any server by sending a command message containing the server and port details.  After receiving the instructions, the malware starts to send packets to the specified address.

The malware reduces the performance of the infected device. The victim will get unexpected bills for accessing Internet and SMS.

#OpFreeTibet : Anonymous targets Chinese government sites

dangerous hackers

The Anonymous hacker group has launched an operation called "#OpFreeTibet" agianst Chinese Government websites.

They have pasted the list of target websites in the Pastebay.  It includes  Ministry of Foreign Affairs(,Ministry of Science & Technology(,,,, and more sites.

Here you can find the full list:

The message posted by hackers to the Chinese Government:

It has come to our attention that protests in Tibet have been escalating in recent weeks and continue to do so. Tibetan monks are disappearing and since March 2011, nearly 60 people are known to have set themselves on fire in protest against the repressive Chinese occupation of Tibet.

The Chinese invasion of Tibet has resulted in the deaths of hundreds of thousands of Tibetans and the imprisonment and torture of thousands more.

We think it's time the Chinese government and its big corporations became targets in order to remind them that the world is watching, Anonymous is watching and that the religious & political suppression of the Tibetan people must stop.

Human rights in Tibet are non-exist with Chinese authorities stopping at nothing to suppress dissent. The Tibetan people have no right to protest and political prisoners are subject to torture.

A message to the Government of China: For too long we have witnessd your tyranny over the people of Tibet and this demonstration is to let you know of our displeasure in your actions.
Recently, they hacked into the official website of Jilin City Public Security Bureau Traffic Police Department by exploiting the SQL injection vulnerability. They've leaked the username and hashed password in pastebay.
