Are We Overexposing Ourselves on Social Networks?

Posted on 07:37 by Unknown

   

Facebook, Twitter, Google+, YouTube, Pinterest, LinkedIn and other social networks have become an essential part of online lives. Social networks are a great approach to stay connected with others, but you should always be aware about how much personal information you post...
A Consumer Reports in 2012 investigation indicates 13 million U.S. Facebook users are oversharing — and likely don’t know it. That figure represents 8 percent of Facebook’s 150 million U.S. users, but it is part of an upward trend in users failing to protect themselves while on the social network — putting themselves at risk in the real world.
Most U.S. tweens, 10- to 12-year-olds, have at least one social media account and many go online without any supervision from their parents, according to a survey released on Tuesday.

Facebook is the most popular platform among tweens. Although the site says users must be at least 13 years old to log on, 85 percent of tweens said they have an account and a similar number admit they use it every day.
The threats to children of unsupervised use of the Internet are well known and range from identity theft, cyberbullying and sharing photos and videos to pornography and sexual predators.
Your social media reputation may also affect the possibility of you finding a job. It used to be that job candidates were judged on their resume, cover letter and references before the in-person interview. But now with social media, job candidates are being fully examined before even stepping foot into a human resources department, and some college students might find themselves at a disadvantage.

According to a survey conducted Abine Inc., an online privacy company, only 60% of graduates are not concerned about their online profiles affecting their ability to secure or keep a job, and experts say a candidate’s online presence and the content they post can make or break a job opportunity.
“Your digital footprint says a lot about you--it’s extremely accessible and the majority of employers are checking it and doing their due diligence on you just like you should do it on them when you’re applying for a job,” says Sarah Downey, privacy analyst at Abine. “There’s a lot of stuff out there that can either hurt you or help you depending on how on top of it you are.”
Here are 5 online dangers that you expose yourself to when connecting with people at any of these social networking sites:

Malware: Being social media today is all the rage it's quite easy to find large volumes of active users at any of these popular sites! This has created a target for those who have a 'twisted'  interest in planting malware on the computers of others! All it takes is for somebody to click on the 'wrong' link and bingo, your hardware or software have now been infected!

Phishing: Scam artist have found a new home on the internet and it suits their purposes perfectly! Where else are these 'bottom feeders' going to find an environment with so many potential and unsuspecting targets! Phishing for sensitive and private information has never been easier than within an environment where connecting with people on a social level is users prime objective! Do you REALLY know who it is you're talking to or sharing your thoughts or information with at these communities?

Damaged Reputation: One of the most common online dangers for anybody who uses social media today is that whatever they say is there for the entire world to see! As a result these sites are typically used as part of a screening process or background check by potential employers or other organizations! Getting 'caught up' in the moment when making comments or offering opinions can easily come back to haunt you!

StaySafeOnline.org has prepared a few tips and tactics for you to follow to ensure that you’re not sharing too much information on social networks:

Have your family follow these tips to safely enjoy social networking:
•    Privacy and security settings exist for a reason: Learn about and use the privacy and security settings on social networks. They are there to help you control who sees what you post and manage your online experience in a positive way.
•    Once posted, always posted: Protect your reputation on social networks. What you post online stays online. Think twice before posting pictures you wouldn’t want your parents or future employers to see. Recent research (http://www.microsoft.com/privacy/dpd/research.aspx) found that 70% of job recruiters rejected candidates based on information they found online.
•    Your online reputation can be a good thing:  Recent research (http://www.microsoft.com/privacy/dpd/research.aspx) also found that recruiters respond to a strong, positive personal brand online. So show your smarts, thoughtfulness, and mastery of the environment.
•    Keep personal info personal: Be cautious about how much personal information you provide on social networking sites. The more information you post, the easier it may be for a hacker or someone else to use that information to steal your identity, access your data, or commit other crimes such as stalking.
•    Know and manage your friends: Social networks can be used for a variety of purposes. Some of the fun is creating a large pool of friends from many aspects of your life. That doesn’t mean all friends are created equal. Use tools to manage the information you share with friends in different groups or even have multiple online pages. If you’re trying to create a public persona as a blogger or expert, create an open profile or a “fan” page that encourages broad participation and limits personal information. Use your personal profile to keep your real friends (the ones you know trust) more synched up with your daily life.
•    Be honest if you’re uncomfortable: If a friend posts something about you that makes you uncomfortable or you think is inappropriate, let them know. Likewise, stay open-minded if a friend approaches you because something you’ve posted makes him or her uncomfortable. People have different tolerances for how much the world knows about them respect those differences.
•    Know what action to take: If someone is harassing or threatening you, remove them from your friends list, block them, and report them to the site administrator.

Protect Yourself with these STOP. THINK. CONNECT. Tips:
•    Keep a clean machine: Having the latest security software, web browser, and operating system are the best defenses against viruses, malware, and other online threats.
•    Own your online presence: When applicable, set the privacy and security settings on websites to your comfort level for information sharing. It’s ok to limit how you share information.
•    Make passwords long and strong: Combine capital and lowercase letters with numbers and symbols to create a more secure password.
•    Unique account, unique password: Separate passwords for every account helps to thwart cybercriminals.
•    When in doubt, throw it out: Links in email, tweets, posts, and online advertising are often the way cybercriminals compromise your computer. If it looks suspicious, even if you know the source, it’s best to delete or if appropriate, mark as junk email.
•    Post only about others as you have them post about you.

Ransomeware

Posted on 16:09 by Unknown
The following is a link to the newest scam out there. It's called "Ransomware"  I just recently had to clean two computers infected with this particular one. This one freezes their computer and accuses you of committing heinous crimes, like distributing child porn. "You have been viewing or distributing child porn ... violating article 202 of the Criminal Code of the United States of America," says one version, allegedly sent by the FBI.  The threats sound real enough that victims are coughing up $200 to pay a "fine," Of  course this is a scam to get your $200. Check-out the following link for the full story.

What is the difference between: Spam, Phishing and Spoofing

Posted on 07:37 by Unknown
Hello and welcome to another installment of the Kesar Tech blog. I have received several emails asking what the difference between Spam, Phishing, & Spoofing is? Here is what I found out.

Spam

Also known as unsolicited bulk e-mail messages or any email messages irrespective of content that is unwanted or unrequested by the recipient. Spam messages are mostly commercial advertising, although chain letters, political mailings and other forms of non-commercial mailings are often included under the same categorization. A large portion of spam has also been found to be comprised of ads for products of dubious quality and services of questionable legality.

There are two types of spam: intentional and unintentional.
  • Intentional spam comes from spammers who are soliciting products or attempting to commit fraud.
  • Unintentional spam originates from computers that are infected with a virus or worm that activates e-mail distribution processes in the background. The virus or worm attempts to send bulk messages from the infected computer without the awareness of the computer owner.


Phishing
Phishing is a special type of spam that is intended to trick you into entering your personal or account information for the purpose of breaching your account and committing identity theft or fraud.
Typically, a false e-mail message is delivered to you. The e-mail appears to come from a legitimate source, for example eBay, your bank, government departments etc. The message may contain a legitimate corporation's logo, and appear to be sent from the corporation's e-mail address. The message may ask you to click a link in the message to update your account, or run a software program to upgrade your computer.
Although the message looks legitimate, it is really trying to compel you to submit your personal and confidential information, which will be used to steal your credentials. Normally you are asked to enter information such as your name, date of birth, place of birth, social security number, mother's maiden name, bank account number, and bank account PIN. Web sites that are frequently spoofed by phishers include PayPal, eBay, MSN, Yahoo, BestBuy, and America Online.


Spoofing

Spoofing is the forgery of an e-mail header so that the message appears to have originated from someone or somewhere other than the actual source. Spoofing is often used by spammers and can be accomplished by changing your "FROM" e-mail address.
E-mail spoofing may occur in different forms, but all have a similar result: a user receives email that appears to have originated from one source when it actually was sent from another source. E-mail spoofing is often an attempt to trick the user into making a damaging statement or releasing sensitive information, such as a password. E-mail spammers often use spoofing in an attempt to get recipients to open, and possibly even respond to, their solicitations.
To send spoofed e-mail, senders insert commands in headers that will alter message information. It is possible to send a message that appears to be from anyone, anywhere, saying whatever the sender wants it to say. Thus, someone could send spoofed e-mail that appears to be from you with a message that you didn't write.

I know this is a lot of information, but I hope it helps.
As always, keep your questions & comments coming.

Fake phone call from Microsoft

Posted on 07:20 by Unknown
The following is an email that I received and responded to. This is the second time in a month that I have had to address this phone scam. As you will read, someone posing as a Microsoft rep. calls the house and says you are loaded with viruses and they need access to your pc to clean it up. You are given a web address to go to and they will “take care of the rest.” As far as I can tell, this is a scam to get control of your pc and steal personal info. Bill Gates & Microsoft have much more important stuff to do then let you know you have a virus. Be on the look out for this and don’t become a victim.



“IT'S A SCAM!!! A friend of mine's daughter got the same phone call in South
Carolina about a moth ago.
As far as I can figure out, they want you to give them access to your pc.
Probably to steal any personal info you have stored on it.
Microsoft has no way, that I know of, to monitor your system. Even if they
did, I really don't think they are going to call you about a virus.
You did the right thing by not giving him any info.
Defender is most likely off because of Comodo. It should give you the
option to turn it back on.
FYI: I think you have Vista & not Windows 7 or 8.
Hope this helps.

Keith”

“New question I just got a phone call from someone (India sounding)
saying I have a virus on the Windows program . He wanted me to turn on
my computer and he would lead me through fixing it. I checked the *69
and could not get the number that called me. I did tell him I had no way
to know who I was talking to or to prove he was legal nor did I get a
letter form Microsoft. I checked and Microsoft defender is off is this
because I have comodo? He had my name and knew I had windows, I do not
remember if he knew I had 7 or 8.”

Beware of malicious Blackhat SEO poisoning.

Posted on 08:55 by Unknown
The following article talks about how sometimes when we search with Bing, Google, Ask, etc.. we can get redirected to a bad website full of scareware. (http://en.wikipedia.org/wiki/Scareware ). Most of these come when you search "hot topics." So be careful what you search for and look for redirects.

The All-In-One PC.

Posted on 08:00 by Unknown
I have been ask about the All-in-one pc a lot lately. Attached, you will find an article about them. Here are my thoughts on them.  They are neat, space saving little machines and I don’t have enough experience with them to give an honest answer. Based on the research I’ve done on them, I can give my opinion. When dealing with them, an old saying comes to mind., “Don’t put all your eggs in one basket.” If one item goes bad , it all goes bad. Just like the 4-in-one copier/fax/scanner/printer. If the copier goes out, maybe the scanner will still work, maybe not. Same thing goes here. If the screen gets damaged, you just can’t run to Best Buy and buy a new monitor. Heaven forbid an internal devices goes bad like the hard drive or video card. You need to be a surgeon / auto body man to change it out. First you have to use a dent puller (suction cups) to carefully remove the glass that covers the screen. The glass is held on by about a dozen magnets. Too much pressure one way or the other and CRACK you just broke the glass. If you successfully remove the glass, now you have another dozen T-5 torque screws to remove. Then open the case about an inch and with a pair of long tweezers, unplug a wire (which you must use the same tweezers to plug back in when reassembling it.) Now unscrew the LCD screen and unplug two more wires to tilt the screen forward to get to the “guts’ of the pc. A few more steps and you are ready to reassemble it. Sounds like fun, doesn’t it? Next comes cost, which can range anywhere from $900 up to $1300. I think these computers serve a purpose for a certain group of people, like college kids and people with limited space. The choice is yours. Just make sure you do your homework before purchasing one. Hope this helps.
