Black Friday (or Thursday, or Monday, or whatever) is approaching and marks the “official” kickoff of the holiday shopping season. According to the National Retail Federation, if the trend holds, this season will be busier than last for online merchants, increasing approx. 4.9% to $602 billion this year. That’s good news for merchants, who make most of their profits for the year during the holiday season.
It’s also good news for cybercrooks.
Criminals will be vying for their share of the revenues by victimizing unwary shoppers seeking to get the most out of their holiday shopping dollar. Offering super low prices on name brand and designer merchandise is their favorite trick. Here are ten tips for secure online shopping that will help you avoid online shopping fraud this season.
- If the price seems too good, it probably is. That cheap Rolex watch is either a fake, stolen or is really a “Rolev.” Beware.
- Crooks duplicate well-known websites to the last detail. Check the domain. If it’s different than the site, leave quickly.
- Poor grammar and obvious mistakes in spelling are a good reason to avoid shopping on the site.
- Never shop on an insecure website. Make sure you see “https://” in the URL.
- Avoid merchants with no customer service phone number. If there is a number, call it to verify it’s real.
- Avoid merchants with email addresses that don’t match the site’s domain name, e.g., gmail or yahoo addresses.
- Don’t use a debit card; you risk your entire bank account. Use a credit card with buyer protection. Pay Pal is a good option.
- Check public reviews of the site to see what others have experienced.
- Keep all receipts and emails related to the transaction until you have received your products.
- The safest option by far is to simply shop at known reputable sites or sites you have prior successful dealings with.
There is no such thing as being 100% secure online, but if you follow these guidelines, you should be OK.
Security is a dynamic process, never a one-time set-it-forget-it thing. As such, I periodically review and attempt to improve the security of my systems. For some years now, I have been a loyal and happy user of LastPass. Every login to every site I use on a regular (and not-so-regular) basis is stored there. One of the services that LastPass provides is their Security Challenge which examines your password vault, gives you an overall security score, and tells you what to do to improve your security. Here’s my most recent result:
I just scored 73% on the LastPass Security Challenge ranking 69029th overall. It securely analyzes the strength of your passwords, alerts you if you have any duplicate or weak passwords, and tells you how to make them more secure.
Give it a try and see if you can beat my score!
Not a bad score — probably much better than the average person — but I’m not happy with it. Out of carelessness, or just plain laziness, I’ve been guilty of the the biggest password no-no of all: using duplicate passwords on different sites. Seems I’ve used 22 different passwords multiple times on 65 different sites. Moreover, I have 24 passwords that are considered weak and (yikes!) three blank passwords.
So, I’ll spend a few hours of my weekend changing passwords and eliminating duplicates and weak ones.
It’s that special day again: Halloween! And this is once again my Happy Halloween message to you. I thought about changing it to something different, but I honestly can’t think of a more appropriate message.
IMHO, no writer in history embodies the essence of Halloween more than Edgar Allen Poe whom I consider the creator of the horror genre (yes, I know he’s credited as the creator of detective-fiction and contributor to the science fiction genre but he dealt more in the macabre than anything else).
Poe’s short story, “The Gold Bug,” is what got me interested in ciphers and encryption as a young boy; a collection of his most popular short stories is what inspired me to become a writer.
So, on this Halloween 2013 I present a very special reading of Poe’s famous poem, “The Raven.” Enjoy!
The bad guys love to trick people into downloading their malicious garbage and will use just about any tactics to do so. It’s Halloween season, so people will be searching for all kinds of scary stuff to decorate, dress up and generally celebrate the creepy. The hackers know this and will have already started putting up poisoned search results. Haven’t heard about any yet? Believe me, they are out there lying in wait for some unsuspecting victim.
How can you tell if you click on a poisoned search result? Video codecs are a favorite vehicle for hackers. If you get a pop-up saying you have to install such-and-so codec or some sort of image viewer, chances are it’s an attempt to infect you. But this isn’t the only method used; when you click on a search engine result, be aware of anything that doesn’t look or feel right. Lots of drive activity, very slow page loading, unusual error messages, any of these things can indicate an attempt to infect your system.
Hackers love holidays and news events because people can be counted on to search for related information, but the above advice applies to routine searches as well. Nothing is immune to being exploited or used as a vehicle for malware, so keep your eyes (and ears) open all the time. I know how my systems act so well that I can spot trouble long before the system crashes.
Don’t let Halloween malware ruin your day.
Since it’s National Cyber Security Awareness Month, I think it’s fitting to re-post my short 2008 piece on using the hosts file to block unwanted sites. I looking it over, I discovered that FaltronSoft no longer exists, hence the strikethrough. The MVPS.org site, however, still exists and is actively maintained with current information. You can sign up at the site to be notified of updates.
Using a HOSTS file to block access to malicious or unwanted web sites is an old trick and it’s excellent protection against malware. I’ve been using the mvps.org hosts file for about five years, and I have never been infected with any malware, despite, for testing purposes, intentionally visiting sites known to host it. The thing just works. It’s a great way to add an additional layer of security to your machine. You’ll also notice that many of those annoying ads no longer display in your browser.
Today, I found a cool utility that will let you download, install, and update your HOSTS file directly from the mvps.org site: Hosts File Updater, a freeware program by FaltronSoft. This single 16K executable checks the mvps.org site for a new version of the HOSTS file. If it finds one, it asks you if you want to update. Give your permission and the program backs up your existing HOSTS file and downloads and installs the new one. It also automatically sets the file to read-only, a nice feature.
In Using the Windows Host File for Privacy and Security, techsupportalert.com has this to say:
Employing the Windows Hosts file to prevent a PC from connecting to undesirable web addresses is a very old practice that is still being used by some as a security measure or to block ads and cookies. Experienced PC users will be familiar with the Hosts file but, if it is a new concept to you, you can read about how this simple text file works at this link. You should also look at what Gizmo wrote about the file in his newsletter ten years ago.
I, for one, have been using this method successfully for years. Give it a try.
CryptoLocker is a particularly nasty piece of malware that encrypts dozens of file types including .doc, .xls, .ppt, .pst, .dwg, .rtf, .dbf, .psd, .raw, and .pdf then demands you pay a “ransom” to get the key to unlock your data. If you see this pop-up on your PC, you’ve been infected:
They make it sound bad, don’t they. Truth is, there is probably no way to get your data unless you risk paying the money to the criminals. Here’s what Windows Secrets has to say about it:
There are no patches to undo CryptoLocker and, as yet, there’s no clean-up tool — the only sure way to get your files back is to restore them from a backup.
Some users have paid the ransom and, surprisingly, were given the keys to their data. (Not completely surprising; returning encrypted files to their owners might encourage others to pay the ransom.) This is, obviously, a risky option. But if it’s the only way you might get your data restored, use a prepaid debit card — not your personal credit card. You don’t want to add the insult of identity theft to the injury of data loss.
That last part is very good advice, but you still risk losing your money and not getting your data back. How can you trust a criminal to keep their promise?
You best strategy at this time is prevention. Antivirus software won’t catch CryptoLocker and limiting admin rights on your computer has no effect, either. To ensure that you will be able to recover your data, the most reliable method is frequent backups. Should CryptoLocker slam you, restoring your data from backup will save your bacon.
If you are running Windows XP Professional or higher, you can set Group Policy to prevent execution of the malware. If you are technically inclined and adventurous, BleepingComputer.com has a comprehensive guide of some things you can try that might work to help you recover data.
We probably all agree that passphrases can be easier to remember than complex, random passwords. IhaveABIG2013truck! can be memorized in just a couple of minutes whereas Ih*^29xB@@!dude would take a lot longer to commit to memory. This isn’t to say that passphrases can’t also be difficult to remember.
Athletes, artists, musicians, craftsmen – anyone who develops a particular manual skill – rely on muscle memory to a greater or lesser extent. As a musician, I know that repetitive practice of scale patterns, chords, picking patterns and melodic riffs trains the muscles in my fingers to “remember” those patterns. At first, I feel awkward and perform slowly, but after a while, the patterns come second nature and take little thought to perform.
You can do the same thing with passphrases and passwords. In fact, the best typists usually don’t think about what they are typing: the key patterns for whole words are trained into the muscle memory of their fingers.
An innovative approach to utilizing muscle memory is to choose passwords and passphrases that alternate between left hand and right hand on the keyboard. The rhythm 0f going back and forth will soon be ingrained into your fingers. This requires some knowledge of touch typing, but don’t worry, you can get familiar enough with it in just a few short lessons on line. Here’s something that may help you. The image shows the “home” keys and you can probably easily figure out which hand goes with which keys.
A random password like A*#9tU is a left, right, left, right pattern. For passphrases, there are hundreds of words that alternate in this manner. Below is a sampling from a list called lrwords.txt that you can find here:
Add in some numbers or special characters that alternate hands and you’ve got the advantage of unusual passphrases that use both your mental and physical memory. How about fiendish1927emblem? Easily memorized and has a nice rhythm on the keyboard. Type it a few times and it’s not likely you’ll forget it.
On October 3, Adobe was hacked and 3 million user accounts were compromised. The attack exposed customer names, encrypted credit and debit card numbers, expiration dates, and other information. Adobe is resetting the passwords on all customer accounts. Here’s the text of the notification I received early this morning:
We recently discovered that an attacker illegally entered our network and may have obtained access to your Adobe ID and encrypted password. We currently have no indication that there has been unauthorized activity on your account.
To prevent unauthorized access to your account, we have reset your password. Please visit www.adobe.com/go/passwordreset to create a new password. We recommend that you also change your password on any website where you use the same user ID or password. In addition, please be on the lookout for suspicious email or phone scams seeking your personal information.
We deeply regret any inconvenience this may cause you. We value the trust of our customers and we will work aggressively to prevent these types of events from occurring in the future. If you have questions, you can learn more by visiting our Customer Alert page, which you will find here.
Adobe Customer Care
Reportedly, Adobe will also be notifying customers whose credit or debit card information was exposed. (I do not have a credit card on file with Adobe, so I just got the password reset notice.) Adobe has also promised to offer affected customers the option of enrolling in a one-year complimentary credit monitoring membership where available.
It’s that time of the month again (no pun intended). It’s Patch Tuesday. It also happens to be the 10th anniversary of the celebrated (not) monthly visitor (sorry, they just keep coming). Microsoft released eight new security bulletins—four rated as Critical and four Important. The most urgent one, however, is MS13-080—the cumulative security update for Internet Explorer. It addresses a total of 10 separate vulnerabilities affecting all supported versions of the Web browser:
This security update resolves one publicly disclosed vulnerability and nine privately reported vulnerabilities in Internet Explorer. The most severe vulnerabilities could allow remote code execution if a user views a specially crafted webpage using Internet Explorer. An attacker who successfully exploited the most severe of these vulnerabilities could gain the same user rights as the current user. Users whose accounts are configured to have fewer user rights on the system could be less impacted than users who operate with administrative user rights.
Other Critical patches:
MS13-081: Vulnerabilities in Windows Kernel-Mode Drivers Could Allow Remote Code Execution (2870008)
MS13-082: Vulnerabilities in .NET Framework Could Allow Remote Code Execution (2878890)
MS13-083: Vulnerability in Windows Common Control Library Could Allow Remote Code Execution (2864058)
Better get patching!
October 1 marked the start – and the 10th anniversary of – National Cyber Security Awareness Month (NCSAM). Sponsored by the Department of Homeland Security in cooperation with the National Cyber Security Alliance and the Multi-State Information Sharing and Analysis Center, NCSAM is an initiative aimed at making sure everyone has the resources they need to stay safer and more secure online.
We all can do our part by educating family, friends and coworkers on how to use the internet safely. The average person really has little clue about the dangers lurking in cyber space and even if they have an inkling, they are far too trusting of what their clueless friends routinely send them. In their defense, cyber security is not easy and the last ten years have shown us a wide range of security threats that test the mettle of even the most savvy cyber security professional.
Sophos has posted 10 topical tales, “in vaguely chronological order, that have burst into our collective security concerns at various times in the last decade.” It’s an interesting list and will give you some food for thought as well as real examples you can use to educate your people.
In another post, Sophos recommends that you do these 3 essential security tasks for your family today.
