What Risk We are Posing! Everyone Can Become Target of the Latest Cyber Security Threats

What Risk We are Posing! Everyone Can Become a Target of the Latest Cyber Security Threats
According to a report by the Washington Post, hackers may soon be setting up a plan to unfold in 2013 that will target 30 different U.S. banking institutions. McAfee Labs, who has compiled a new cyber security report, says that banks should be on the lookout for software that creates false online transactions or targets transfers tied to large dollar amounts.
Sources say that these threats can all be tied back to “Project Blitzkrieg”, which is a program that has been around since 2008. Within the past four years, it has already stolen $5 million and plans to continue for as long as possible. During the past few months, between 300 and 500 victims located within the U.S. have fallen victim to Project Blitzkrieg’s schemes. By the spring of 2013, McAfee says that things could get even worse for U.S. banks and their customers.
Experts note that this scheme may be tied to reports from back in October by security company RSA that mentioned how a hacker out of Russia named “vorVzakone” has been openly discussing his plan to recruit a team to plan the largest Trojan attack tied to banking. McAfee warns that these threats should be taken extremely seriously as the beginning of 2013 is soon to unfold. The software can become extremely dangerous to those doing their banking online because it can replicate transactions and even delete e-mail notifications about certain transfers.
While U.S. banks will no doubt be increasing their security protocols to protect themselves from any unnecessary attacks, most already know that they are continually being cited as targets from hacking groups around the globe. Back in September, both JP Morgan Chase and Bank of America saw their sites crash because of DDoS attacks.

Samsung Smart TV Dangers
The Register has recently reported that Samsung’s newest Smart TV is completely open and vulnerable to hacking because it gives hackers the ability to steal data very quickly. According to security company ReVuln, this vulnerability most notably affects consumers who own and use their Samsung 3D TVs for internet purposes.
Those who use their Smart TVs can rent movies, browse the web for a cheap line rental, go on Facebook, and more. ReVuln claims that they have found an exploit which allows hackers to see everything the user is doing while they are using their TV, retrieve and access information like web history, and hook up an external thumb drive to the TV to conveniently steal all of this information for future use. While ReVuln noticed this exploit while using a Samsung 3D TV, the true problem is that it seems to affect all of the latest Samsung TVs with internet capabilities, which includes many different makes and models.
As these TVs continue to act more as larger PCs, it is only a matter of time until we see even more security vulnerabilities tied to them in the very near future.

Gas Station Bluetooth Skimming
News site KRCA out of Sacramento notes that crooks are using Bluetooth devices in order to steal credit card information from those who are paying for gas at the pump. The biggest issue the cyber security experts noticed is that these thieves do not even have to be near the gas station in order to steal information.
Crooks are using skimming devices that utilize Bluetooth and contain a variety of common security keys that can be used to access gas pumps for maintenance. They don’t simply pull out their device and begin swiping information for oblivious consumers. Thieves will start by installing skimmers on the pumps to collect information from those pumping gas and then pick them back up. Detectives say that these types of devices are impossible to detect.
According to experts, thieves can be up to 100 yards away and continually collect credit card information from unsuspecting users. Because of this, these crooks are impossible to detect, and the problem may only grow larger in the near future.

Troublesome QR Codes

QR codes seem to be everywhere these days. They’re typically on everything from advertisements to products that we purchase on a daily basis. In the Netherlands, hackers are posting QR codes in heavily trafficked areas like airports and major streets. When these QR codes are scanned in by a user’s smart phone, they are taken to a malicious website that may attempt to phish information from the user or possibly infect their smartphone with malware.

VOGH Exclusive: URL Redirection Vulnerability Found In Facebook

VOGH Exclusive: URL Redirection Vulnerability Found In Facebook [The Vulnerability Still Active & Not Been Patched]
Facebook -the world's largest social networking site with registered users of more than one billion, is considered among one of the safest site of the cyber space. To maintain such reputation Facebook Inc has done all the required steps, that one could possibly take. Like other high profile and very popular websites, Facebook also stand as one of the hot target of almost every cyber criminals of the world. To get rid of this and make FB safe and secure, the company have introduced what it called 'Bug Bounty' offer; where you can submit vulnerabilities to FB and get rewarded. We have seen many security researchers and hackers across the globe has done this and get their award. But not every time, and today I will talk about that- few days ago a reader of VOGH, who also goes by the nick name of 'Dr41DeY' has figured out a URL redirection vulnerability in Facebook. One of the link in Facebook App which is apps.facebook.com is posing URL redirection vulnerability. The hacker has demonstrated how any one can use  the vulnerability  in order to manipulate millions of innocent Facebook users. Let see  

Before publishing this, one of our VOGH representative have talked with Facebook Security regarding this security vulnerability, but due to some reason FB might overlooked this issue. Finally after waiting for almost a week, we the Team VOGH decided to bring this in-front of our reader. Let briefly go through with the vulnerable link-

Replace voiceofgreyhat.com with any of your favorite site, and the the said vulnerability will allow you to get redirected to that very website you want to from Facebook. This loophole is still active, and any one can test that with the above url, we thought the impact of this loophole is very serious, as any malicious attacker can misuse the trust-hod of Facebook's url in order to harm regular internet users, while redirecting them to any junk or malfunctional websites.

Disclaimer:- Earlier I told that the issue has already brought into the notice of Facebook Security, but they overlooked the whole issue, so being a responsible cyber media, we VOGH are disclosing this to people. If any one misuse this vulnerability, then Voiceofgreyhat will not at all be responsible for any kind of mishap.

Update:- May be doing more that what we call late repent, but finally the above disclosed vulnerability has been patched by Facebook security team.

Skype Shop & National Geographic Germany (Nat Geo) Vulnerable to XSS

Skype Shop & National Geographic Germany (Nat Geo) Vulnerable to XSS -Said Dr41DeY
Couple of weeks ago, I have talked about the vulnerability of Cartoon Network official website, today I am going to speak about two more big fish who are posing serious security holes in their official websites. Lets not waste time while stretching the preface and come directly to the story -it's the hacker who has recently made his name for some big hacks, has back again. 
Many of you are right, I am talking about 'Dr41DeY' because he is the guy who found vulnerability in the official website of Skype Shop and National Geographic Channel Germany (Nat Geo). Both Nat Geo and Skype have non persistent cross site scripting vulnerability also known as XSS vulnerability in their website. We have already informed this issue to concerning authority and webmaster to avoid misfortune. As expected, while writing this Skype have taken this issue seriously and fixed their loopholes immediately. Still for proof- above I have shared the screenshots with our readers, as evidence of the XSS hole. But unlike Skype Shop, Nat Geo yet not responded, so the vulnerability still exist on their portal. Hopefully they will take appropriate steps with out doing more delay. For updates in this story and also other hot cyber issues, just stay tuned with VOGH.  Before concluding, I would like to remind you that- in 2012 an Indian hacker named Akshay has found XSS holes in the official website of National Geographic. Again after a year, Dr41DeY found another Nat GEO site vulnerable to XSS, that definitely arises a doubt about the security concern of one of the world's leading satellite television channel featuring documentaries with factual content involving nature, science, culture, and history, plus some reality and pseudo-scientific entertainment programming.

Cartoon Network (CN) Official Website is Vulnerable to XSS Attack

XSS Vulnerability Found in Cartoon Network's (CN) Official Website By Dr41DeY 
After the successful breach of 'DY365 TV' yet again the hacker going by the name of Dr41DeY from Nigerian Cyber Army targeted another TV network. Guess what, this time he caught even a bigger fish. Unlike defacement or breach this time the hacker did something what it called ethical or can be categorized in white-hat list. Okey now without pulling the intro more longer lets directly come to the story -and that is the official website of Cartoon Network is vulnerable of cross site scripting attack also known as XSS attack. Cartoon Network mostly known as CN is the worlds leader in broadcasting  animated programming, ranging from action to animated comedy & many more. This satellite channel is the most preferred channel for the children and teenagers between the ages of 7 to 5 among the whole of the world. So it is quit indisputable that the official website of Cartoon Network (CN) is indeed a valuable website which have large number of traffic everyday. But it is unclear that being such a big and popular brand name, why CN committed such a massacre while leaving XSS vulnerability in their official portal. Dr41DeY shared with VOGH, that the search box in the home page of CN poses non persistent XSS vulnerability. The above screen shots was taken as a proof of the story. I on behalf of Team VOGH has already contacted CN authorities, and knocked them about this issue. Hopefully they will take appropriate steps with out doing any further delay. For updates in this story and also other hot cyber issues, just stay tuned with VOGH.

We Are The Best Tool For Web Application Security (Discovering Infamous Sql-i Technique)

We Are The Best Tool For Web Application Security (Discovering The Infamous Sql-injection Technique) 

Today I am proudly sharing an article made by Mr. Rafael Souza one of the great admirer and fan of VOGH has gladly shared his brilliant research paper on SQL-Injection (MySql) with us. Rafael is a very passionate on cyber security domain and he is keenly involved with GreyHat Community and Maintainer design of Brazilian Backtrack Team. So without wasting time lets go and see what Rafael has for us:- 

Discover The Infamous MySQL Injection Technique 
                                                                                        
ABSTRACT:
It is known that computers and software are developed and designed by humans, human error is a reflection of a mental response to a particular activity. Did you know that numerous inventions and discoveries are due to misconceptions?
There are levels of human performance based on the behavior of mental response , explaining in a more comprehensive, we humans tend to err , and due to this reason we are the largest tool to find these errors , even pos software for analysis and farredura vulnerabilities were unimproved by us.
                                                                                                       
Understand the technique MySQL Injection: 
One of the best known techniques of fraud by web developers is the SQL Injection. It is the manipulation of a SQL statement using the variables who make up the parameters received by a server-side script, is a type of security threat that takes advantage of flaws in systems that interact with databases via SQL. SQL injection occurs when the attacker can insert a series of SQL statements within a query (query) by manipulating the input data for an application.

Readers, this article is for educational purposes only, could continue explaining how to exploit web sites, but that is not my intention.
It is known that the impact of the change may provide unauthorized access to a restricted area, being imperceptible to the eye of an inexperienced developer, it may also allow the deletion of a table, compromising the entire application, among other features. So I want to emphasize that this paper is for security researcher and developers to beware and test your code.

CONCLUSION
Many companies are providing important information on its website and database, information is the most valuable asset is intangible, the question is how developers are dealing with this huge responsibility?
The challenge is to develop increasingly innovative sites, coupled with mechanisms that will provide security to users.
The purpose of this paper is to present what is SQL Injection, how applications are explored and techniques for testing by allowing the developer to customize a system more robust and understand the vulnerability.
**********
I hope you all will enjoy the above article, as I did. On behalf of entire VOGH Team I am sincerely thanking Mr. Rafael Souza for his remarkable contribution.

Apple Brings iOS 7.0.4 [Includes New Features, FaceTime Bug & App Store Purchase Flaw Fixed]

Apple Brings iOS 7.0.4 & iOS 6.1.5 Includes New FeaturesFaceTime Bug  & App Store Purchase Flaw Fixed


California based tech giant Apple Inc has released a new update on their popular iOS software running on iPhone, iPad, and iPod touch devices. This release of of iOS 7.0.4  includes bug fixes and improvements, including a fix for an issue that causes FaceTime calls to fail for some users. iPods that are not able to upgrade to iOS 7 have their own version to upgrade to, iOS 6.1.5. The release of iOS 7.04 marks the third update of the iPhone operating system in the short time since Apple pushed out iOS 7 in September. The new OS represented a major change from the older operating systems, both in the look and feel of the software and in its functionality.  There’s much zooming in and out and all about in iOS 7, as well as a blurry background that has drawn quite a bit of criticism. iOS 7 also was a major security release, fixing issues with the iPhone’s certificate trust policy as well as remote code-execution vulnerabilities in the CoreGraphics and CoreMedia components. 

The new update improves iCloud Keychain, which was introduced in iOS 7.0.3, and the latest version of the desktop software, OS X Mavericks. The cloud-based technology keeps the Safari browser's passwords and credit card data in sync across all your Apple devices. Secondly, in Spotlight, the device's internal search engine, Apple has brought back the ability to search Google and Wikipedia from the results. The two services were removed when iOS 7 was first released in mid-September. 
Also on Thursday, Apple released a corresponding update to its Apple TV, updating the set-top box to version 6.0.2.  Users can update to the latest version by accessing the device's Settings, selecting General, then Software Update. In spite of the relatively small size of the update, it's recommended that users use Wi-Fi when updating. To avoid security vulnerabilities every Apple users are highly recommended to update their software.

Hackers Exploiting Old Ruby on Rails Vulnerability To Compromise Web Servers & Create Botnet

Hackers Exploiting Old Ruby on Rails Vulnerability (CVE-2013-0156) To Compromise Web Servers & Create IRC Botnet
A critical vulnerability on Ruby on Rails spotted in January this year which was deemed “critical” at the same time yet again found in the wild. The vulnerability known as CVE-2013-0156 that affected versions 3.0.20 and 2.3.16 again rises it's hand. Though a security patch was released by the Rails developers. But as we all know that many server administrator used to be unaware of these events have not patched their systems. As a result hackers and cyber criminals are actively exploiting a critical vulnerability in the Ruby on Rails Web application development framework in order to compromise Web servers and create a dangerous botnet. This major security issue was first discovered by a security consultant Mr. Jeff Jarmoc of research firm Matasano Security. In his blog Jarmoc said "It’s pretty surprising that it’s taken this long to surface in the wild, but less surprising that people are still running vulnerable installations of Rails. It also appears to be affecting some web hosts." According to his blog post -the exploit that's currently being used by attackers adds a custom cron job -- a scheduled task on Linux machines that executes a sequence of commands. Those commands download a malicious C source file from a remote server, compile it locally and execute it. The resulting malware is a bot that connects to an IRC (Internet Relay Chat) server and joins a predefined channel where it waits for commands from the attackers. A pre-compiled version of the malware is also downloaded in case the compilation procedure fails on the compromised systems.
"Functionality is limited, but includes the ability to download and execute files as commanded, as well as changing servers," Jarmoc said. "There's no authentication performed, so an enterprising individual could hijack these bots fairly easily by joining the IRC server and issuing the appropriate commands." But the matter of relief is that Jarmoc concluded while saying "this is a pretty straightforward skiddy exploit of a vulnerability that has been publicly known, and warned about, for months."

But still administrators who have not yet patched their Rails version should immediately should update the Ruby on Rails installations on their servers to at least versions 3.2.11, 3.1.10, 3.0.19 or 2.3.15 which contain the patch for this vulnerability. However, the best course of action is probably to update to the latest available Rails versions, depending on the branch used, since other critical vulnerabilities have been addressed since then. 

Brief About RoR:- Ruby on Rails is a popular framework for developing Web applications based on the Ruby programming language and is used by major websites including Hulu, GroupOn, GitHub and Scribd.

ESET one of the world renowned security firm headquartered in Bratislava have figured out what it called a malicious cyber rampage targeting millions of cPanel-based servers. Since last few months security experts have been tracking server level compromises that have been utilizing malicious Apache modules to inject malware into websites and  redirecting some of its requests to the infamous Blackhole Exploit packs. On cPanel-based servers, instead of adding modules or modifying the Apache configuration, the attackers started to replace the Apache binary (httpd) with a malicious one. This new backdoor is very sophisticated and this new malware has been dubbed "Linux/Cdorked.A." Several analysis reveals that it is a sophisticated and stealthy backdoor meant to drive traffic to malicious websites. According to the official blog post of ESET - Linux/Cdorked.A is one of the most sophisticated Apache backdoor's we have seen so far. The backdoor leaves no traces of compromised hosts on the hard drive other than its modified httpd binary, thereby complicating forensics analysis. All of the information related to the backdoor is stored in shared memory. The configuration is pushed by the attacker through obfuscated HTTP requests that aren't logged in normal Apache logs. This means that no command and control information is stored anywhere on the system.
This malicious cyber rampage was first detected by another security firm named 'Sucuri' and later ESET published a detailed analysis of the issue. But still there are thoughtful matter as already thousands of websites get infected. The attack is particularly dangerous as Apache web servers are among the most well-known and widely-used in the world and are used by numerous companies. This means that a successful security breach can affect numerous different businesses across a diverse range of industries.
As this malware also known as Linux/Cdorked.A has already been spotted in the wild, so on behalf of cyber media, we urge all the concern system administrator, security analyst to take care of the above issue while to checking their servers and verify that they are not affected by this threat. Detailed instructions to perform this check are provided in the ESET blog.

42 Java Holes Fixed By Oracle in April 2013 Critical Patch Update Advisory

42 Java Holes Fixed By Oracle in April 2013 Critical Patch Update (CPU) Advisory

The Oracle Corporation has released what it called a critical patch update for its Web-based Java programming language. Java SE software that fixes at least 42 security flaws in the widely-installed program and associated browser plugin. The Java update also introduces new features designed to alert users about the security risks of running certain Java contentThe April patch, which targets 42 vulnerabilities, 19 of which have a severity rating of 10 (highest possible threat level) includes a majority of vulnerabilities that are currently being exploited. Among those 42 new security fixes across Java SE products of which 2 are applicable to server deployments of Java.  According to Oracle, “39 of these vulnerabilities may be remotely exploitable without authentication, i.e., may be exploited over a network without the need for a username and password.” Along with the fixes, Oracle changed the default setting of Java SE. Java applets will no longer run in a Web browser unless they have been digitally signed until a warning prompt is acknowledged. It has also extended how users will be alerted of other Java-related security issues. According to renowned security expert and blogger Brian KrebsJava 7 Update 21 also introduces some new security warnings and message prompts for users who keep the program plugged into a Web browser (on installation and updating, Java adds itself as an active browser plugin). Oracle said the messages that will be presented depend upon different risk factors, such as using old versions of Java or running applet code that is not signed from a trusted Certificate Authority. Apps that present a lower risk display a simple informational message. This includes an option to prevent showing similar messages for apps from the same publisher in the future. Java applications considered to be higher risk — such as those that use an untrusted or expired certificate — will be accompanied by a prompt with a yellow exclamation point in a yellow warning triangle.

Affected Product Releases and Versions:-
Java SEPatch Availability
JDK and JRE 7 Update 17 and earlierJava SE
JDK and JRE 6 Update 43 and earlierJava SE
JDK and JRE 5.0 Update 41 and earlierJava SE
JavaFX 2.2.7 and earlierJavaFX

Due to the threat posed by a successful attack, Oracle strongly recommends that customers apply CPU fixes as soon as possible. As Java has been run by millions of devices and users across the globe, so we urge all of our readers to install and apply the security fixes to avoid any kind of threats. Note that - Oracle said that this week's security updates don't take care of all known flaws, they do address all known vulnerabilities currently being exploited in the wild.

PostgreSQL Fixed “Persistent Denial-of-Service” Vulnerability (CVE-2013-1899)

PostgreSQL Fixed 'High-Exposure Security Vulnerability' Causing Denial-of-Service Attack (CVE-2013-1899)

Security researcher's have yet again figured out a serious security hole in one of most widely used object-relational database management system, PostgreSQL also known as Postgres. While manipulating the loophole an attacker can easily corrupt files and in some cases, can execute malicious code on underlying servers causing "persistent denial-of-service" attack. By corrupting the files an attacker can cause database server to crash and refuse to reboot. Affected servers could only be restarted by removing garbage text from the files or by restoring them from a backup. Versions 9.0, 9.1, and 9.2 are all vulnerable. As soon as this vulnerability get spotted, the developers at PostgreSQL immediately  released updates while addressing a "high-exposure security vulnerability in versions 9.0 and later." The updates are available for 9.0, 9.1, and 9.2 branches, as well as 8.4. This updates also allow PostgreSQL to be built using Microsoft Visual Studio 2012. According to developers: "A major security issue fixed in this release, CVE-2013-1899, makes it possible for a connection request containing a database name that begins with "-" to be crafted that can damage or destroy files within a server's data directory. Anyone with access to the port the PostgreSQL server listens on can initiate this request. This issue was discovered by Mitsumasa Kondo and Kyotaro Horiguchi of NTT Open Source Software Center." In addition to fixes for one major security issue, the updates also include four more minor security fixes, as well as fixes for other, non-security-related issues. 

Some of these fixes include:
  • A security vulnerability that made contrib/pgcrypto-generated strings too easy to guess;
  • A vulnerability that would allow unprivileged users to interfere with backups;
  • Security issues involving the OS X and Linux installers;
  • Vaious issues with GiST indices;
  • An issue related to crash recovery; and
  • Memory and buffer leaks, among others.

The complete list of fixes and enhancements in each version can be found on the PostgreSQL release notes archive page. Also the patched PostgreSQL 9.2.4, 9.1.9, 9.0.13, and 8.4.17 are available now at download  page. While talking about this fix, we would like to remind you that, late in last year another security vulnerability hit PostgreSQL database system, including versions 9.1.5, 9.0.9, 8.4.13 and 8.3.20. The security holes associated with libxml2 and libxslt. Along with that a vulnerability in the built-in XML functionality, and a vulnerability in the XSLT functionality supplied by the optional XML2 extension.
