Avoid a Phishing Scam Online

 

The act of sending email that falsely claims to be from a legitimate organization. This is usually combined with a threat or request for information: for example, that an account will close, a balance is due, or information is missing from an account. The email will ask the recipient to supply confidential information, such as bank account details, PINs or passwords; these details are then used by the owners of the website to conduct fraud.

Phishing is when a scam artist sends a message to trick you into providing your personal information. The scam artists then use that information to steal your identity and your money.

There are ways to protect yourself against phishing scams online that are easy and should be done by everyone.

Blank Computer Virus

Computer viruses are a reality and you are likely to encounter one on your own computer at some point. Some of these can be quite harmless, but others can cause chaos. Knowing what to do in such a situation will be beneficial for you in restoring your PC to proper operating order; however if you are unsure of how to correct a problem, it might be better to consult a computer technician.

 

Explanation

 

If you come across the About:blank screen when you use Internet Explorer, odds are that it may be a virus. The About:blank screen virus is a browser hijacker which is designed to take control of your web browser. The main purpose of this browser hijacker is to redirect you to more dangerous sites in an attempt to download viruses and spyware to your computer and to access your private information.

 

Cleaning

Removing the About:blank virus is possible, and you can find many step-by-step guides on the Internet to help you. You can also download spyware-removal software specifically for this problem, and these programs can be located by doing a simple search online. It is also recommended that you have an updated antivirus program that can detect and remove this virus before any avoidable harm comes to your operating system.

Viruses

Viruses and malware are specifically programmed to harm operating systems or to collect sensitive information from users. Although most of them will easily be picked up by good antivirus software, some of them might sneak in without the user's knowledge. These are the ones to be concerned about because you might not notice them until they have caused damage to your PC

Prevention

The best tool to use against computer attacks is a current antivirus program. Antivirus software companies work to find solutions to new viruses and attacks every day. Updating your antivirus definitions and performing regular scans will help prevent the About:blank virus from infecting your computer.

Technology

Technology is a critical tool in our daily lives and can unfortunately become one of our worst enemies as well. With cyber crime increasing by the day and new viruses being deployed, you are constantly vulnerable to these threats. Knowledge is power and by arming yourself with the right information, tools and software you can ensure that your data and system are safe from attackers.

Rootkit With Ubuntu

Rootkit viruses are designed to be impossible to detect by users and antivirus software. These viruses burrow themselves deep underneath standard computer processes, often residing below the operating system function within the system BIOS, operating system kernel or within little-used libraries. By doing this, rootkit infections can be difficult to remove using standard software and in some cases, the rootkit application can escape antivirus and anti-spyware removal by injecting itself into other levels of the operating system.

True Myths About Computer Viruses

One of the main reasons viruses have become such a threat to today's computer systems is the fact that modern viruses are different in almost every way from what they were in the past. But most computer users are aware of these changes and their idea of enough protection against viruses, worms, and Trojan horses it is still less than what is necessary. Some myths have turned into real situations as time passed by.

Virus and Its Properties

A computer virus is a small software program that spreads from one computer to another computer and that interferes with computer operation.Viruses can spread from one system to another system on a network. Computer viruses are most easily spread by attachments in e-mail messages or by instant messaging messages. Therefore, you must never open an e-mail attachment unless you know who sent the message or unless you are expecting the e-mail attachment. Computer viruses also spread by using downloads on the Internet. Computer viruses can be hidden in pirated software or in other files or programs that you may download. A true virus can spread from one computer to another, when its host is taken to the target computer. They are platform independent which means it can affect any operating system depending on its programming function. They can even disable or destroy hardware.

Hijacking Google services!

An international research team has demonstrated the possibility of hijacking Google services and reconstructing users’ search histories. Firstly, with the exception of a few services that can only be accessed over HTTPs (e.g. Gmail), researchers found that many Google services are still vulnerable to simple session hijacking.

Next they presented the Historiographer, a novel attack that reconstructs the web search histories of Google users, i.e. Google’s Web History, even though such a service is supposedly protected from session hijacking by a stricter access control policy. The Historiographer implements a reconstruction technique that rebuilds the search history based on inferences received from the personalized suggestions fed to it by the Google search engine. The attack was based on the fact that Google’s users receive personalized suggestions for their search queries based on previously searched keywords. The researchers showed that almost one third of monitored users were signed in to their Google accounts, and of those, half had their Web History enabled, thus leaving themselves vulnerable to this type of attack.

The research data was sent to Google and the company has decided to temporarily suspend search suggestions from Search History in addition to offering Google Web History pages over secure protocol HTTPs only.

Software vulnerabilities in computing!!

In computer security, a vulnerability is a weakness which allows an attacker to reduce a system's information guarantee.

Software vulnerability is commonly called a "bug" in software which may allow a third party or program to gain unauthorized access to some resource. Software vulnerability control is one of the most important parts of computer and network security for the following reasons.

• Virus programs use vulnerabilities in operating system and application software to gain unauthorized access, spread, and do damage.
• Intruders use vulnerabilities in operating system and application software to gain unauthorized access, attack other systems, and do damage.
• Some software itself may be hostile.

If software vulnerabilities did not exist, I believe that viruses would not exist and gaining any unauthorized access to resources would be very difficult indeed.

This may be due to weak security rules, or it may be that there is a problem within the software itself. In theory, all computer systems have vulnerabilities; whether or not they are serious depends on whether or not they are used to cause damage to the system.

A software vulnerability is a state in a computing system (or set of systems) which either:

• allows an attacker to execute commands as another user
• allows an attacker to access data that is contrary to the specified access restrictions for that data
• allows an attacker to pose as another entity
• allows an attacker to conduct a denial of service

When an attack is made possible by a weak or inappropriate security policy, this is better described as 'exposure':

An exposure is a state in a computing system (or set of systems) which is not a universal vulnerability, but either:

• allows an attacker to conduct information gathering activities
• allows an attacker to hide activities
• includes a capability that behaves as expected, but can be easily compromised
• is a primary point of entry that an attacker may attempt to use to gain access to the system or data is considered a problem according to some reasonable security policy

When trying to gain unauthorized access to a system, an intruder usually first conducts a routine scan (or investigation) of the target, collects any 'exposed' data, and then exploits security policy weaknesses or vulnerabilities. Vulnerabilities and exposures are therefore both important points to check when securing a system against unauthorized access.

Only approved software should be operated on the organization's network. This is so hostile programs cannot gain access to the network. Hostile programs may be written with some useful functionality, but may perform a hidden task that the user is not aware of. This type of hostile program is normally called a "Trojan Horse". The ways to help determine whether a program is hostile may include:

• Does the progam come from a reliable source?
• Is there proof that the program came from the source such as a digital signature?
• If the source code is available for the program, the code may be checked to be sure there is no hostile content.
• A reliable third party may be able to check out the software and certify that it is safe.
• Does the creater of the program attempt to hide their identity? If the creator of the program attempts to hide their identity then there may be reason for suspicion. If the program creater does not hide their identity and can be reached, it is less likely that the program is a hostile program.
• Has this program been run by other people or organizations for some period of time with no adverse consequences?

Computer security is not an exact science and it is a matter of reducing the chance of an intrusion. Probably the best method of being sure of the reliability of a program is to allow a reliable third party to check the program. I believe it is likely that these services may become more popular in the future. Program writers may even send source code to these service providers for certification with source code covered by a nondisclosure agreement.

Dangerous Celebrities in Cyberspace!!

This year, the search results for celebrities are safer than they've been in previous years, but there are still dangers when searching online. "Through consumer education and tools, consumers are getting smarter about searching online, yet cybercriminals are getting sneakier in their techniques. Now they're hiding malicious content in 'tiny' places like shortened URLs that can spread virally in social networking sites and Twitter, instead of on websites and downloads.

Cameron Diaz has been named the most dangerous celebrity on the web for 2010 by a top security firm.

Research by the security firm, which has been acquired by Intel, revealed that web users searching for images, screen savers and videos of the 'Knight and Day' actress have a one in ten chance of being presented with results that lead to malicious web pages.

According to the research, cybercriminals often use the names of popular celebrities to trick web users into visiting sites infected with malicious software. Those navigating to the site could find the malware installed on their computers.

Pretty Woman star Julia Roberts was named the second most dangerous celebrity on the web, while Justin Timberlake's current girlfriend, Jessica Biel, took third place.

Also said that while movie stars and models top the 'most dangerous' list this year politicians including US President Barack Obama and Sarah Palin are among the safest celebrities to search for on the net.

The top 10 celebrities from this year’s study with the highest percentages of risk are:

Position	Celebrity
1	Cameron Diaz – Searching for Diaz results in a one in ten chance of landing on a risky site. She has most recently been in the spotlight with blockbuster movies, "Knight and Day" and "Shrek Forever After." When "Cameron Diaz and screensavers" was searched, 19% of the sites were identified as containing malicious downloads.
2	Julia Roberts – Academy Award-winning actress Julia Roberts is one of America's sweethearts, and will soon be in the spotlight with her upcoming release of "Eat, Pray, Love." The overall risk of searching for Roberts is nine percent, yet searching for "Julia Roberts and downloads" results in a 20% chance of downloading a photo, wallpaper or other file laden with malware.
3	Jessica Biel – Last year's Most Dangerous Celebrity fell two spots with searches resulting in fewer risky sites this year. Biel continues to be in the spotlight with her on-again, off-again relationship with Justin Timberlake, and appeared in "The A-Team" in June 2010. While her overall search risk is 9%, searching for "Jessica Biel and screensavers" results in a 17% chance of landing on a risky site.
4	Gisele Bündchen – The world's highest-paid supermodel moved up two spots since last year. Searching for "Gisele Bündchen and screensavers" can prove risky, 15% of the search results for this beauty can put spyware, malware or viruses on your computer.
5	Brad Pitt – Pitt is often in the spotlight with news of his movies and his personal life. It's no wonder why this leading man has been in the top ten for the past three years. He moved up in rank five spots this year. Downloading photos, screensavers, or other files of Brad can potentially put adware or spyware in your computer.
6	Adriana Lima – Searching for downloads of this Brazilian beauty can direct users to red-ranked sites. Lima is best known for being a Victoria's Secret Angel since 2000.
7	Jennifer Love Hewitt, Nicole Kidman – Searching for these Hollywood starlets resulted in an equal number of risky download websites.
8	Tom Cruise – With recent buzz around his MTV Awards performance as well as his movie, "Knight and Day," Cruise rises to the top ten.
9	Heidi Klum, Penelope Cruz – Both of these ladies are consistently in the spotlight, and share the #9 spot. Cybercriminals use their names to lure people to risky sites. Klum hosts "Project Runway" and Cruz has been in the spotlight recently for her role in the "Sex and the City 2" movie and is expected to be in the fourth film of the "Pirates of the Caribbean" series.
10	Anna Paquin – This "True Blood" star is as dangerous on the web as she is on the screen. Searching for screensavers of Paquin can lead you to downloads filled with malware.

Cybercriminals follow the same hot topics as consumers, and create traps based on the latest trends. Whether you’re surfing the Web from your computer or your phone or clicking on links in Twitter about your favorite celeb, you should surf safely, and make sure you’re using the latest security software.
