SplashData has announced its annual list of the 25 most common passwords found on the Internet. For the first time since SplashData began compiling its annual list, “password” has lost its title as the most common and therefore Worst Password, and two-time runner-up “123456″ took the dubious honor. “Password” fell to #2.
The 2013 list of worst passwords, influenced by postings from the Adobe breach, demonstrates the importance of not basing passwords on the application or website being accessed.

A few companies pay money to bug hunters. But Facebook is giving out something more unique than just a check. Some security researchers are getting a customized “White Hat Bug Bounty Program” Visa debit card. The researchers, who can make thousands of dollars for reporting just one security hole on the social-networking site, can use the card to make purchases, just like a credit card, or create a PIN and take money out of an ATM. As the researchers find more bugs, Facebook can add more money to their accounts. A team of security researchers have demonstrated how a security flaw in Android 4.0.4 can be exploited by a clickjacking rootkit. The research team is lead by North Carolina State University professor Xuxian Jiang, who succeeded in developing a proof-of-concept rootkit that attacks the Android framework as opposed to the underlying operating system kernel. The researchers contend that such a rootkit could potentially be downloaded with an infected app and be used to manipulate the smartphone.
In the video, the demonstrator was able to hide applications on the device, as well as get them to launch when icons for other applications are clicked. If downloaded with an infected application, the rootkit could for example hide the smartphone’s browser and replace it with a browser that looks exactly the same but actually steals all of the user’s information. On the car forum 1Addicts, a one-time poster by the name of “stolen1m” uploaded the video showing how his BMW was stolen in under three minutes. He suspects the thieves used devices that plug into the car’s On-Board Diagnostic (ODB) port to program a new keyfob.
In this particular video, there are a few security flaws that the hackers are exploiting simultaneously: there is no sensor that is triggered when the thieves initially break the window, the internal ultrasonic sensor system has a “blind spot” just in front of the OBD port, the OBD port is constantly powered (even when the car is off), and last but not least, it does not require a password. All of this means the thieves can gain complete access to the car without even entering it. BMW has acknowledged that there is a problem, but is downplaying this particular issue by saying the whole industry struggles with thievery. This is unfortunate given that the evidence seems to point towards BMWs being specifically targeted. Whether that’s because they are luxury cars or because they have a security loophole doesn’t matter: the point is BMW needs to do something about it. If you want to protect yourself from this hack, look into how you can disable the OBD port on your BMW by disconnecting the corresponding wires. If you or your dealer needs it, you can always reenable it. Alternatively, you can try to further secure the port in your own custom way. Yahoo is investigating the claims of a hacker who is selling an exploit that apparently hijacks Yahoo mail accounts. The exploit, being sold for $700 by an Egyptian hacker on an exclusive cybercrime forum, targets a cross-site scripting (XSS) weakness in yahoo.com that lets attackers steal cookies from Yahoo! Webmail users. Such a flaw would let attackers send or read email from the victim’s account. In a typical XSS attack, an attacker sends a malicious link to an unsuspecting user; if the user clicks the link, the script is executed, and can access cookies, session tokens or other sensitive information retained by the browser and used with that site. These scripts can even rewrite the content of the HTML page. Demonstrating an apparent flair for marketing, the hacker, under the alias “TheHell” also posted a video on YouTube, providing a demo for potential customers. He claims it works with all browsers and does not require a bypass of XSS filters in either Chrome or Internet Explorer. He also says the exploit will be sold only to trusted individuals who are not likely to turn it over to Yahoo, which would undoubtedly develop a patch that will foil the attack. “TheHell” claims that his exploit attacks a “stored” XSS flaw. This type of attack injects a code that is permanently stored on targeted servers until it is found and deleted. The malicious code is then passed to the victim’s machine when that particular server is accessed for legitimate download. A standard phishing attempt is used to access the user’s cookies, from which the attacker can access the person’s email, or take full control of the account. As of Tuesday morning, Yahoo was in the process of trying to identify the infected URL. Once the identification is successful, the malicious portion of code will be deleted. Mirror link will redirect you to your own profile page. If you share the link with your friend, when he/she click on it, it reopen his/her page. Just like am mirror, it reflects user's own profile.

A new variant of the Ramnit worm has managed to steal log-in credentials for several thousand Facebook accounts, most of which were from the United Kingdom and France, according to researchers at Seculert. Evidence recovered from a command-and-control server used to coordinate the evolving Ramnit worm confirms that the malware has already stolen 45,000 Facebook passwords and associated email addresses.Discovered in April 2010, the Microsoft Malware Protection Center (MMPC) described Ramnit as “a multi-component malware family which infects Windows executable as well as HTML files”, “stealing sensitive information such as stored FTP credentials and browser cookies”. In July 2011 a Symantec report [PDF] estimated that Ramnit worm variants accounted for 17.3 percent of all new malicious software infections. Trusteer previously reported in August of last year Ramnit gained the ability to “bypass two-factor authentication and transaction signing systems, gain remote access to financial institutions, compromise online banking sessions and penetrate several corporate networks.” Seculert, using Sinkhole, found that 800,000 machines had been infected with the worm in the last quarter of 2011. All email communications on the internet are possible by two protocols:
1) Simple Mail Transfer Protocol (SMTP port-25) 2) Post Office Protocol (POP port-110) E-Mail hacking consists of various techniques as discussed below. 1) EMail Tracing :- Generally, the path taken by an email while traveling from sender to receiver can be explained by following diagram. Sender's Outbox----->Source Mail Server----->Interim Mail Server----->Destination Mail Server------>Destination Inbox. The most effective and easiest way to trace an email is to analyze it's email headers. This can be done by just viewing the full header of received email. A typical email header looks something like this: From Barr Thu Jan 3 05:33:26 2008 X-Apparently-To: [email protected] via 203.104.16.34; Thu, 03 Jan 2008 05:25:38 +0530 X-YahooFilteredBulk: 189.160.34.89 X-Originating-IP: [189.160.34.89] Return-Path: <[email protected]> Authentication-Results: mta113.mail.in.yahoo.com from=destatis.de; domainkeys=neutral (no sig) Received: from 189.160.34.89 (HELO dsl-189-160-34-89.prod-infinitum.com.mx) (189.160.34.89) by mta113.mail.in.yahoo.com with SMTP; Thu, 03 Jan 2008 05:25:38 +0530 Received: from dvapa ([141.203.33.92]) by dsl-189-160-34-89.prod-infinitum.com.mx with Microsoft SMTPSVC(6.0.3790.0); Wed, 2 Jan 2008 18:03:26 -0600 Message-ID: <[email protected]> Date: Wed, 2 Jan 2008 18:03:26 -0600 From: "Barr" <[email protected]> Add to Address Book User-Agent: Thunderbird 2.0.0.6 (Windows/20070728) MIME-Version: 1.0 To: [email protected] Subject: angel rubberneck Content-Type: multipart/related; boundary="------------030604060204000701040304" Content-Length: 16433 The above email header gives us the following information about it's origin and path: a) Sender's email address :- [email protected] b) Source IP address :- 141.203.33.92 c) Source mail server :- dsl-189-160-34-89.prod-infinitum.com.mx d) Email client :- Thunderbird 2.0.0.6 There are lots of ready-made tools available on the internet which performs email tracing very effectively and shows exact geographical location for email sender on the world map.

Input Validation Attacks are where an attacker intentionally sends unusual input in the hopes of confusing the application.
The most common input validation attacks are as follows- 1) Buffer Overflow :- Buffer overflow attacks are enabled due to sloppy programming or mismanagement of memory by the application developers. Buffer overflow may be classified into stack overflows, format string overflows, heap overflows and integer overflows. It may possible that an overflow may exist in language’s (php, java, etc.) built-in functions. To execute a buffer overflow attack, you merely dump as much data as possible into an input field. The attack is said to be successful when it returns an application error. Perl is well suited for conducting this type of attack. Here’s the buffer test, calling on Perl from the command line: $ echo –e “GET /login.php?user=\ > `perl –e ‘print “a” x 500’`\nHTTP/1.0\n\n” | \ nc –vv website 80 This sends a string of 500 “a” characters for the user value to the login.php file. Buffer overflow can be tested by sending repeated requests to the application and recording the server's response. 2) Canonicalization :- These attacks target pages that use template files or otherwise reference alternate files on the web server. The basic form of this attack is to move outside of the web document root in order to access system files, i.e., “../../../../../../../../../boot.ini”. This type of functionality is evident from the URL and is not limited to any one programming language or web server. If the application does not limit the types of files that it is supposed to view, then files outside of the web document root are targeted, something like following- /menu.asp?dimlDisplayer=menu.asp /webacc?User.asp=login.htt /SWEditServlet?station_path=Z&publication_id=2043&template=login.tem /Getfile.asp?/scripts/Client/login.js /includes/printable.asp?Link=customers/overview.htm 3) Cross-site Scripting (XSS) :- Cross-site scripting attacks place malicious code, usually JavaScript, in locations where other users see it. Target fields in forms can be addresses, bulletin board comments, etc. We have found that error pages are often subject to XSS attacks. For example, the URL for a normal application error looks like this: http://website/inc/errors.asp?Error=Invalid%20password This displays a custom access denied page that says, “Invalid password”. Seeing a string on the URL reflected in the page contents is a great indicator of an XSS vulnerability. The attack would be created as: http://website/inc/errors.asp?Error=<script%20src=... That is, place the script tags on the URL. 4) SQL Injection :- This kind of attack occurs when an attacker uses specially crafted SQL queries as an input, which can open up a database. Online forms such as login prompts, search enquiries, guest books, feedback forms, etc. are specially targeted. The easiest test for the presence of a SQL injection attack is to append “or+1=1” to the URL and inspect the data returned by the server. example:- http://www.domain.com/index.asp?querystring=sports' or 1=1-- enjoy!!! |
