Phishing is Getting Fishier

/0 Comments/in , /by

If you are like most people, you have undoubtedly received an email that has asked you to click on a link. Did you click it?

If you did, no worries, you are just like 99% of internet users – everyone has clicked a link before, it is pretty normal. But, in some situations, you may have found that the link took you to a new or maybe spoofed website where you might be asked to do “something”, i.e. enter some information or even login to an account. Once you entered your username and password, they have it…

If you have ever done so, you were likely a victim of what is known as a phishing attack, and these attacks are getting fishier all of the time.

A What? Phish? Fish?

It’s called a phishing attack, and yes, it’s a play on words. When you fish, you throw a hook and worm into the water and hope you catch something. Hackers do the same when they phish.

Except, their hook and worm, in this case, is an carefully crafted email – designed to look like something you should get – which hackers hope you are going open…its then, that they can reel you in.

There are a few different types of phishing:

  • Spoofed websites – Hackers phish by using social engineering. Basically, they will send a scam email that leads to a website that looks very familiar. However, it’s actually a spoof, or imitation, that is designed to collect credit card data, usernames and passwords.
  • Phishing “in the middle” – With this type of phishing, a cybercriminal will create a place on the internet that will essentially collect, or capture, the information you are sending to a legitimate website.
  • Phishing by Pharming – With phishing by pharming, the bad guys set up a spoof website, and redirect traffic from other legitimate sites to the spoof site.
  • Phishing leading to a virus – This is probably the worst phish as it can give a criminal full control over your device. The socially engineered phish is designed to get you to click a link to infect your device.

Can You Protect Yourself from Phishing?

Yes, the standard rule is “don’t click links in the body of emails”. That being said, there are emails you can click the link and others you shouldn’t. For example, if I’ve just just signed up for a new website and a confirmation email is then sent to me, I’ll click that link. Or if I’m in ongoing dialog with a trusted colleague who needs me to click a link, I will. Otherwise, I don’t click links in email promotions, ads or even e-statements. I’ll go directly to the website via my password manager or a Google search.

Top 10 Signs of a Malware Infection on Your Computer

/0 Comments/in , , /by

Not all viruses that find their way onto your computer dramatically crash your machine. Instead, there are viruses that can run in the background without you even realizing it. As they creep around, they make messes, steal, and much worse.

Malware today spies on your every move. It sees the websites you visit, and the usernames and passwords you type in. If you login to online banking, a criminal can watch what you do and after you log off and go to bed, he can log right back and start transferring money out of your account.

Here are some signs that your device might already be infected with malware:

  1. Programs shut down or start up automatically
  2. Windows suddenly shuts down without prompting
  3. Programs won’t start when you want them to
  4. The hard drive is constantly working
  5. Your machine is working slower than usual
  6. Messages appear spontaneously
  7. Instead of flickering, your external modem light is constantly lit
  8. Your mouse pointer moves by itself
  9. Applications are running that are unfamiliar
  10. Your identity gets stolen

If you notice any of these, first, don’t panic. It’s not 100% that you have a virus. However, you should check things out. Make sure your antivirus program is scanning your computer regularly and set to automatically download software updates. This is one of the best lines of defense you have against malware.

Though we won’t ever eliminate malware, as it is always being created and evolving, by using antivirus software and other layers of protection, you can be one step ahead. Here are some tips:

  • Run an automatic antivirus scan of your computer every day. You can choose the quick scan option for this. However, each week, run a deep scan of your system. You can run them manually, or you can schedule them.
  • Even if you have purchased the best antivirus software on the market, if you aren’t updating it, you are not protected.
  • Don’t click on any attachment in an email, even if you think you know who it is from. Instead, before you open it, confirm that the application was sent by who you think sent it, and scan it with your antivirus program.
  • Do not click on any link seen in an email, unless it is from someone who often sends them. Even then, be on alert as hackers are quite skilled at making fake emails look remarkably real. If you question it, make sure to open a new email and ask the person. Don’t just reply to the one you are questioning. Also, never click on any link that is supposedly from your bank, the IRS, a retailer, etc. These are often fake.
  • If your bank sends e-statements, ignore the links and login directly to the banks website using either a password manager or your bookmarks.
  • Set your email software to “display text only.” This way, you are alerted before graphics or links load.

When a device ends up being infected, it’s either because of hardware or software vulnerabilities.  And while there are virus removal tools to clean up any infections, there still may be breadcrumbs of infection that can creep back in. It’s generally a good idea to reinstall the devices operating system to completely clear out the infection and remove any residual malware .

As an added bonus, a reinstall will remove bloatware and speed up your devices too.

Phishing 101: How Not to Get Hooked

/in , , /by

You’d think that it would be as easy as pie to avoid getting reeled in by a phishing scam. After all, all you need to do is avoid clicking on a link inside an email or text message. How easy is that?

A phishing scam is a message sent by a cybercriminal to get you to click on a link or open an attachment. Clicking on the link or attachment downloads a virus, or takes you to a malicious website (that often looks like real site).

You are then tricked into entering user names, passwords and other sensitive account information on the website that the scammer then uses to take your money, steal your identity or impersonate you.

Intel Security recently designed a quiz to help people identify a phishing email. Sometimes they’re so obvious; for example, they say “Dear Customer” instead of your actual name, and there are typos in the message. Another tip-off is an unrealistic “threat” of action, such as closing down your account simply because you didn’t update your information. Some scammers are more sophisticated than others and their emails look like the real thing: no typos, perfect grammar, and company logos.

The quiz showed ten actual emails to see if all of us could spot the phishing ones.

  • Out of the 19,000 respondents, only 3% correctly identified every email.
  • 80% thought at least one phishing email was legitimate.
  • On average, participants missed one in four fraudulent emails.

The biggest issue may not be how to spot a phishing scam as much as it is to simply obey that simple rule: Don’t click links inside emails from unknown senders! And don’t download or click on attachments. Now if you’re expecting your aunt to send you vacation photos and her email arrives, it’s probably from her.

But as for emails claiming to be from banks, health plan carriers, etc.…DON’T click on anything! In fact, you shouldn’t even open the message in the first place.

And I can’t say this enough: Sorry, but you aren’t special enough to be the one person to be chosen as the recipient of some prince’s lofty inheritance. And nobody wins a prize out of the blue and is emailed about it.

A few more things to keep in mind:

  • An email that includes your name can still be a phishing scam.
  • Don’t fret about not opening a legitimate message. If it is, they’ll call you or send a snail mail.
  • You can also contact the company directly to see if they emailed you anything.

How your Brain is affected by Phishing Scams

/in , /by

A recent study says that people are more mindful of online safety issues than what experts had previously believed. An article on phys.org says that Nitesh Saxena, PhD, wanted to know what goes on in users’ brains when they come upon malicious websites or malware warnings.

13DSaxena points out that past studies indicated that users’ minds are pretty much blank when it comes to malware signs. Saxena and colleagues used brain imaging (functional MRI) for their study.

Study subjects were asked to tell the authentic login pages of popular websites from phony replications. A second task for them was to differentiate between harmless pop-ups while they read some news articles and pop-ups with malware warnings.

The fMRI showed brain activity as it corresponded to the users’ online activity: attention, making decisions, solving problems. The images lit up for both tasks, but of course, fMRI can’t tell if the user is making the right decision.

That aside, the results were that the users were accurate 89 percent of the time with the malware warning task. When users were met with malware warnings, the language comprehension area of the brain lit up. Saxena states in the phys.org article, “Warnings trigger some sort of thought process in people’s brains that there is something unusual going on.”

The accuracy rate of telling an authentic website from a phony one was just 60 percent. Saxena believes this might be because users don’t know what to look for. For instance, they don’t know to look at the URL, which can give away the phoniness.

This study also had the participants complete a personality evaluation to measure impulsiveness. The fMRI images revealed differences based on impulsivity. Saxena says there was a “negative correlation” between brain activity and impulsive behavior. The impulsive user is prone to hastily clicking “yes” to proceed, when a malware warning pops up.

There was less brain activity in the key cerebral areas of decision-making in the users who had greater degrees of impulsivity.

This study has potential applications for the improved design of malware warning systems. These results can also assist company managers by identifying impulsive workers who need stronger online security training.

75 Million Unique Malware Samples By 2012

/0 Comments/in /by

Imagine your body being targeted by 75 million viruses. That is exactly what’s happening to your digital devices. Laptops, desktops, netbooks, notebooks, Macs, iPads, iPhones, BlackBerrys, Androids, and Symbian mobile phones are all being targeted. The most recent threats report from McAfee Labs reveals a grim outlook and a variety of threats.

Mobile: Android has become the most popular platform for new malware, and this past quarter, was targeted exclusively by all new forms of mobile malware. The Symbian OS (for Nokia handsets) remains the platform with the all-time greatest number of viruses, but Android is clearly today’s main target.

Malware: Rootkits, or stealth malware, are one of the nastiest threats we face. They are designed to evade detection, and thus are able to lurk on a system for prolonged periods. Fake AV, also known as fake alert or rogue security software, has bounced back strongly from previous quarters, while AutoRun and password-stealing Trojans remain at relatively constant levels. Mac malware continues to show a bit of growth as well.

Spam: Although spam volume has decreased significantly, McAfee Labs has observed major developments in targeted spam, or what’s often called “spear phishing.” Much like malware, total numbers are dropping but the severity of the threat and sophistication of the technique remain high.

Social engineering: Subject lines used for social engineering spam messages vary depending on geography and language. Bait can include holidays or sporting events, and often differs by month or season. Attackers have shown remarkable insight into what works for specific people at specific times.

Spam botnets: New spam botnet infections continued steadily from February through August of 2011, but dropped somewhat in September.

Bad URLs: Website URLs, domains, subdomains, and particular IP addresses can be “bad” or malicious, either because they are used to host malware, phishing websites, or potentially unwanted programs.

Phishing websites: McAfee identified approximately 2,700 phishing URLs per day during the second quarter of 2011, a slight decrease from the same period in 2010, when they counted 2900 per day.
