Facebook chat-based phishing attack impersonates Facebook Security

A new phishing attack that's spreading through Facebook chat modifies hijacked accounts in order to impersonate the social network's security team.

The attackers replace the profile picture of compromised accounts with the Facebook logo and change their names to a variation of "Facebook Security" written with special Unicode characters, said Kaspersky Lab expert David Jacoby in a blog post.


Facebook claims that changing the profile name can take up to 24 hours and is subject to confirmation. However, in Jacoby's tests the change occurred almost instantly and required only the password. This was also confirmed by a victim whose profile name was modified within 5 minutes of their account being compromised, he said.

After the victim's profile name and picture get changed, the attackers send out a chat message to all of their contacts informing them that their accounts will be suspended unless they re-confirm their information.

The rogue messages appear to be signed by "The Facebook Team" and contain a link to a phishing page hosted on an external domain. The Web page mimics Facebook's design and asks for name, email, password, security question, country, birth date and other information needed to hijack the account.

However, the attack doesn't stop there. According to Jacoby, a second form asks users for their credit card details and billing address. This is somewhat unusual for Facebook phishing attacks, the majority of which target only social networking account information.

"These scams are just getting more popular and we really recommend not giving out personal information, especially not email, password and credit card information over social media," Jacoby said.

World’s Top Most Renowned Hackers


Kevin Mitnick

Kevin David Mitnick (born on August 6, 1963) is a computer security consultant, author, and hacker. In the late 20th century, he was convicted of various computer- and communications-related crimes. At the time of his arrest, he was the most-wanted computer criminal in the United States.

Computer hacking


At age 12, Mitnick used social engineering to bypass the punchcard system used in the Los Angeles bus system. After a friendly bus driver told him where he could buy his own ticket punch, he could ride any bus in the greater LA area using unused transfer slips he found in the trash. Social engineering became his primary method of obtaining information, including user names and passwords and modem phone numbers.


Mitnick gained unauthorized access to his first computer network in 1979, at 16, when a friend gave him the phone number for the Ark, the computer system Digital Equipment Corporation (DEC) used for developing their RSTS/E operating system software. He broke into DEC's computer network and copied their software, a crime he was charged with and convicted of in 1988. He was sentenced to 12 months in prison followed by three years of supervised release. Near the end of his supervised release, Mitnick hacked into Pacific Bell voice mail computers. After a warrant was issued for his arrest, Mitnick fled, becoming a fugitive for two and a half years.


According to the U.S. Department of Justice, Mitnick gained unauthorized access to dozens of computer networks while he was a fugitive. He used cloned cellular phones to hide his location and, among other things, copied valuable proprietary software from some of the country's largest cellular telephone and computer companies. Mitnick also intercepted and stole computer passwords, altered computer networks, and broke into and read private e-mail. Mitnick was apprehended on Valentine's Day, 1995 in Raleigh, North Carolina. He was found with cloned cellular phones, more than 100 clone cellular phone codes, and multiple pieces of false identification.


Gary McKinnon


Gary McKinnon, a Scottish systems administrator has been accused of the biggest military computer hacking exercise of all times by the US government. McKinnon is also accused of copying data, account files and passwords into his own computer. US authorities pegged the cost of tracking and rectifying the problems caused by his hacking at over $700,000.


Gary McKinnon (born 10 February 1966) is a Scottish  systems administrator and hacker who has been accused of what one U.S. prosecutor claims is the "biggest military computer hack of all time,"  although McKinnon himself states that he was merely looking for evidence of free energy suppression and a cover-up  of UFO activity and other technologies potentially useful to the public. After a series of legal proceedings in England, McKinnon is currently fighting extradition  to the United States.



Gary McKinnon, 40, accused of mounting the largest ever hack of United States government computer networks -- including Army, Air Force, Navy and NASA systems The court has recommended that McKinnon be extradited to the United States to face charges of illegally accessing 97 computers, causing US$700,000 (400,000 pounds; euro 588,000) in damage.

Operation AntiSec



Operation Anti-Security, also referred to as Operation AntiSec or #AntiSec, is a series of hacking attacks performed by members of  hacking group LulzSec, the group Anonymous, and others inspired by the announcement of the operation. LulzSec performed the earliest attacks of the operation, with the first against the Serious Organised Crime Agency on 20 June 2011.

Soon after, the group released information taken from the servers of the Arizona Department of Public Safety; Anonymous would later release information from the same agency two more times. An offshoot of the group calling themselves
LulzSec Brazil launched attacks on numerous websites belonging to the Government of Brazil and the energy company Petrobras. LulzSec claimed to retire as a group, but on 22 June they reconvened to hack into the websites of British newspapers The Sun and The Times, posting a fake news story of the death of their owner Rupert Murdoch.

Anonymous released their first cache of the operation on 27 June 2011
, taken from an anti-cyberterrorism program run by the United States Department of Homeland Security and Federal Emergency Management Agency. They continued attacks on the Arizona government. They also launched attacks against the Brazilian government, Government of Zimbabwe, the Municipality of Mosman, and the Government of Tunisia. Their most recent attacks have been against large corporations, NATO, and various United States law enforcement websites. Anonymous has used the stolen credit card numbers of police officers to make unauthorized donations to various causes. Others have also committed hacks in the name of the operation, including a hack into the Fox News Twitter account to post a false news story about the assassination of President of the United States Barack Obama and attacks on the websites of government entities in various countries. The groups involved have published sensitive government and corporate information, as well as the email addresses, names, and social security numbers, and credit card numbers of website users.

Law enforcement has launched investigations into many of the attacks committed as part of Operation AntiSec. At least seven arrests have been made in connection to activities related to the operation, including the arrests of two purported LulzSec members, a man who provided LulzSec with
security vulnerability information, and four alleged members of AntiSec NL, a group inspired by the operation.

How to Remove Ramnit Virus Manual

first of all if you don't know about Ramnit Worm see my previous blog http://anonymousbrat.blogspot.com/2012/01/facebook-hacked-worm-steals-more-than.html

W32.Ramnit is a worm that infects .exe, .dll and .html files to reproduce and infect other systems. After infection, W32.Ramnit will hijack your browser to redirect you to a malicious domain. W32.Ramnit may also make contact with an anonymous third party through Internet Explorer exploits, allowing the remote attacker to violate your privacy and exert control over your computer. Many anti-malware programs have been unable to detect W32.Ramnit in some instances; severe infections can necessitate a complete system wipe to remedy the situation. Be cautious about worms like W32.Ramnit when on large networks or using removable media, and strive to delete W32.Ramnit quickly before it becomes too difficult to remove.

first things W32.Ramnit does is infect any .exe, .dll, or .html files W32.Ramnit can find. If you open these infected files, congratulations - now you've got W32.Ramnit, too! W32.Ramnit may also create concealed Autorun.inf files that are placed on various drives, including removable ones. Any computer that then accesses these drives will also get the W32.Ramnit worm.

Different versions of W32.Ramnit have been identified as a threat since January of 2010, and the worm is far from exterminated yet. Fortunately, indicators of W32.Ramnit's presence are sufficiently plain that you ought to see W32.Ramnit before it's been on your system too long. Deleting W32.Ramnit with sufficient quickness can mean the difference between your computer surviving without damage and your computer needing a complete hard drive wipe.

W32.Ramnit may also be detected under the slight variant names of W32.Ramnit.A and W32.Ramnit.B.

Backup Reminder: Always be sure to back up your PC before making any changes.


To remove W32.Ramnit, you must first stop any W32.Ramnit processes that are running in your computer'ds memory. To stop all W32.Ramnit processes, press CTRL+ALT+DELETE to open the Windows Task Manager. Click on the "Processes" tab, search for W32.Ramnit, then right-click it and select "End Process" key.

To delete W32.Ramnit registry keys, open the Windows Registry Editor by clicking on the Windows "Start" button and selecting "Run." Type "regedit" into the box and click "OK." Once the Registry Editor is open, search for the registry key "HKEY_LOCAL_MACHINE\Software\W32.Ramnit." Right-click this registry key and select "Delete."

Finally, to completely get rid of W32.Ramnit, you must manually remove other W32.Ramnit files. These W32.Ramnit files can be in the form of EXE, DLL, LSP, TOOLBAR, BROWSER HIJACK, and/or BROWSER PLUGIN. For example, W32.Ramnit might create a file like
%PROGRAM_FILES%\W32.Ramnit\W32.Ramnit.exe. Locate and remove these files.

Facebook Hacked: A Worm Steals More Than 45000 Passwords

A famous worm called Ramnit worm has been actively found in the facebook environment. It is reported by Symantec that this worm is responsible for the theft of more than 45k passwords.


According to Cyberthreat management site Seculert, most of the stolen credentials were from US,
UK and France, Furthermore they have added that over the of these stolen logins were invalid and many of them have reacted correctly by changing their username and passwords.

Bypass two-factor authentication and transaction signing systems, gain remote access to financial institutions, compromise online banking sessions and penetrate several corporate networks

Recently, our research lab identified a completely new 'financial' Ramnit variant aimed at stealing Facebook login credentials. Since the Ramnit Facebook C&C URL is visible and accessible it was fairly straightforward to detect that over 45,000 Facebook login credentials have been stolen worldwide, mostly from users in the United Kingdom and France"

Countermeasures:

1. Avoid clicking on any kind of suspicious links.
2. Update your Antivirus Right away.

How file recovery software works

Hi Friends you very well know about how to recover your data through Recovery software’s after deleting from Recycle bin. Today I will discuss how file recovery software actually works.

Files in a computer have a volume table (directory table) that contains, among other things, an entry for each file in the hard disk along with the address of the location where the file is stored. When a file is deleted, a small part of the table for that entry is modified marking the space as free. The data still remain in the disk until it is overwritten at some later time. Now two possibilities arise:

1) The table entry for a deleted file is intact. In this case, it will still contain the pointer to the file. A quick reading of volume table by the file recovery software followed by looking at the location for the file may recover data if it is not overwritten by that time.

2) The table entry itself is overwritten, i.e. some other file entry has replaced the free'd file's entry. In this case, the file recovery software uses Advance mode. In this mode, it scans the whole disk reading each block and matches the files there with entries in the table. That is the reason this option takes a long time. If the file in any block has an associated entry in the table, it means the file is still alive i.e. not deleted, and it skips to next file and its entry. If a file has no corresponding entry in the table, it means this file has been deleted and so the tool marks this as "Found".

The most important step in data recovery after a file is accidentally deleted is to make sure that the disk is immediately detached if one wants to recover the file. Otherwise, the data might get overwritten and not recoverable by such tools. It also means that just deleting a file doesn't ensure the data is gone. One needs a proper tool to erase data. Such tools overwrite the whole data in the disk with random bit patterns many times over rendering it pattern-less and non-recoverable. Hardware techniques also exist to erase data such as degaussing which basically erases data in a disc magnetically.

Search Engine Optimization

Search Engine Optimization is a technique, by which one enables search engines to find and rank your site better than hundreds of thousands of websites in the world wide web, in response to a search query, called Keyword.
Whenever one enters a search query in a search engine and clicks search or hits enter, a list of sites appear. It is general tendency that the viewers visit the sites on the top of the list, as it is perceived that they are more relevant to the search query. Who decides, which sites go on the top of the rankings? Each search engine scans or "crawls” the web reading every page and recording every activity. Sites which are better optimized and relate to a keyword, are favoured more than sites which are not. These crawlers visit the site continuously over staggered intervals of time, depending on the level of activity, looking for changes.
The rankings are dynamic. A site can be on the top of the ranking today, and may drop the next time the search engine updates its ranking, for various reasons like drop in activity, competitors promoting their site very actively and the like. SEO, is not a one time solution, it is a continuous process.

SEO is one of the most powerful online marketing tools, which can boost traffic and increase business through your site. However it should be understood that only SEO does not guarantee top rankings. Different Search engines like Google, Bing, Yahoo, Ask, etc., have their own algorithm for finding and ranking sites. A sit owner should be cautious when he/she is trying to optimize his/her site for different search engines.
