Hackers are using a new exploit for a bug in the out-of-date but popular Java 6 platform to attack victims, and has been added to a commercially available Neutrino exploit kit. The use of Java 6 still is prevalent, opening up a significant number of users to the threat. F-secure analyst Timo Hirvonen warned about the exploit over Twitter, advising that he had found an exploit in the wild actively targeting an unpatched vulnerability in Java 6, named CVE-2013-2463 . The exploit's proof-of-concept was made public last week, prior to in-the-wild attacks surfacing on Monday. Oracle is aware of the hole but, since Java 6 is no longer supported, the company will not patch the issue. The vulnerability lies in Java Runtime Environment's 2D sub-component, which is used to make two-dimensional graphics. Because no patch is available, the exploits provides cybercriminals and other attackers an effective vehicle to launch attacks targeting users and organiz...

Other than Windows, Now other platforms are becoming more popular every day and attracting bad guys who are starting to create malicious code for other systems.  Java applications can run on multiple platforms with ease, thus no surprise that malicious code written in Java that is designed to target more than one operating system are becoming increasingly common. Researchers at McAfee Labs spotted another sample of Java based trojan dubbed as JV/BackDoor-FAZY  that opens a back door for an attacker to execute commands and acts as a bot after infection. According to researcher, The key to decrypt the config file was encrypted with Base 64, Triple-DES algorithm and Hex. Decrypting the file provides information about the backdoor connection, includes IP address, port number, operating system, mutex information, and password for the connection. " On execution, the JAR file opens the backdoor connection to the IP address and the port mentioned in the pla...

Founder and CEO of Security Explorations of Poland,  Adam Gowdiak has reported a new unpatched security vulnerability in JAVA that affects all Java versions, including 7u21 released last Tuesday. Gowdiak claims to have sent to Oracle a report about a reflection API vulnerability in the newly shipped Server Java Runtime Environment (JRE), notifying them of the new security weakness. “ It can be used to achieve a complete Java security sandbox bypass on a target system ,” Vulnerability allows attackers to completely bypass the language's sandbox to access the underlying system. Gowdiak has not published any further details about the vulnerability in order to give Oracle time to patch the problem. Last week’s Oracle patch update repaired many issues plaguing the platform. Java 7 Update 21 contains 42 new security fixes for Oracle Java SE. A majority of these flaws are browse-to–a-hacked-site-and-get-infected vulnerabilities. According to Oracle, “ 3...

Exploit kits are one of the dangerous cyber crime tool, where The Phoenix Exploit Kit is a good example of exploit packs used to exploit vulnerable software on the computers of unsuspecting Internet users. The Phoenix Exploit Kit is available for a base price of $2,200 in underground market by its malware author or developer.  Like other exploit kits , Phoenix also developed to exploit browser-based  vulnerabilities in outdated and insecure versions of browser plugins like Java, and Adobe Flash and Reader. Developer of Phoenix is known by nickname AlexUdakov on several forums. According to new investigation report published by  krebsonsecurity , AlexUdakov was also member of a forum called Darkode , whose administrator accounts were compromised few weeks before and that the intruders were able to gain access to private communications of the administrators.  Intruders was able to view full profiles and database of Dar...

Oracle has released emergency patches multiple of times in recent months for Java for one after another set of vulnerabilities . About 100 million computers reported to be vulnerable to unauthorized access via different flaw in Java software. Department of Homeland Security's US-CERT already warned users to disable Java permanently to stop hackers from taking control of users' machines. Security experts advised,'T he best defense we have right now for these kinds of attacks is to disable Java in the browser forever' . According to Websense experts, Most browser installations use outdated versions of the Java plug-in that are vulnerable to at least one of several exploits used in popular web attack toolkit. Exploit kits are a very common tool for distribution of many Java-based threats. To detect the vulnerable Java versions that are installed on systems and Websense experts, used their technology via ' threat intelligence network' , which monitors bi...

During the first day of Pwn2Own competition at the CanSecWest conference in Vancouver , latest versions of all major browsers were exploited by hackers.  Chrome, Firefox and Internet Explorer 10 on Windows 8 were successfully pwned by various competitors, bringing them tens of thousands of dollars in prizes.  French vulnerability research and bug selling firm ' Vupen ' brought down IE10 running on a Windows 8 powered Surface Pro tablet by exploiting a pair of flaws. Researchers Jon Butler and Nils from MWR Labs managed to exploit Google Chrome on Windows 7 and also used a kernel bug to bypass the sandbox. " By visiting a malicious webpage, it was possible to exploit a vulnerability which allowed us to gain code execution in the context of the sandboxed renderer process. We also used a kernel vulnerability in the underlying operating system in order to gain elevated privileges and to execute arbitrary commands outside of the sandbox with s...

Do you still have Java installed? There is a bad news for you ! FireEye has detected yet another Java zero-day vulnerability being exploited in attacks in the wild. The vulnerability targets browsers that have the latest version of the Java plugin installed Java v1.6 Update 41 and Java v1.7 Update 15 and  FireEye warned that the   vulnerability is being exploited to install a remote-access trojan dubbed McRat , researchers from security firm. " Not like other popular Java vulnerabilities in which security manager can be disabled easily, this vulnerability leads to arbitrary memory read and write in JVM process," "After triggering the vulnerability, exploit is looking for the memory which holds JVM internal data structure like if security manager is enabled or not, and then overwrites the chunk of memory as zero. " The exploit is reportedly different from the one used to attack Facebook, Twitter, Apple, and several other companies last mont...

Once again a zero day vulnerability exploit is sold by cyber criminals in the underground, once again a the flaw is related to Oracle’s Java software that could allow to gain remote control over victim's machine. The news has been reported by KrebsOnSecurity blog that announced that the exploit being sold on an Underweb forum. The vulnerability is related to the most recent version of Java JRE 7 Update 9, it isn't present in previous versions of the framework, in particular the bug resides within the Java class “MidiDevice according the info provided by the seller that describes it with following statements: “ Code execution is very reliable, worked on all 7 version I tested with Firefox and MSIE on Windows 7 ,” “ I will only sell this ONE TIME and I leave no guarantee that it will not be patched so use it quickly. ” The exploited class is a component of Java that handles audio input and output. It's easy to understand that similar vulnerability has a great value du...
