When a phish is so preventable

Filed under: malware, phishing — katrina @ 7:36 am

… not to be confused with pishing or fishing …

This is a criminally fraudulent process used to obtain information electronically such as passwords, credit card details or a persons identity.

Most commonly the phisher uses an email or instant message and tries to bait you with a legitimate sounding request they hope will ‘catch’ your information.

There are several basic techniques used:

  • Fake links - if you don’t look closely you would not notice slight misspellings and think you are going to a real bank or similar site.
  • Website forgery - it is frightening how advanced phishers are becoming with their deceptions
  • Phone - receiving text messages claiming to be from a bank

There are technologies that can assist in protecting you from phishing attacks.

Mozilla Firefox for example has a lot of built in features to assist.

Google is now alerting you through Firefox of attack sites.

BUT

the main protection is for the internet user to BE AWARE of what they are doing and to understand a few important points.

  • No bank will EVER email you about your account details
  • No reputable business will EVER email you about your account details
  • Phishing emails address you as ‘valued customer’ or such rather than with your own name
  • Verify your account is a common phrase
  • If you don’t respond in xx hours or days your account will be closed is a common phrase
  • Asking you to click a link to confirm or access your account
  • Often there are spelling or grammatical mistakes in the email

If you are not sure - contact the business by phone or by a contact you have for them, NEVER by replying or clicking on links in the email!

Always check that the padlock symbol appears when you are logged into any secure web site.

You can report the scam - if in Australia SCAM Watch have links to where you can make your report.

Wikipedia have a good article explaining phishing.

So at the end of the day, you must be vigilant about emails you receive and think before you click.  In some ways phishing is even more insidous than virus and other malware because they rely on YOU to participate.

Protection is all up to what you do

Filed under: Web Info, malware, phishing — katrina @ 6:40 am

There are software tools that assist you in maintaining your computer system no matter what kind of system you have and these are important and have their place.
However one thing I learned years ago, when living on a small farm was – vigilance against ticks is the only way to protect a young dog.  I could spend as much money as I liked on any number of chemicals, but nothing is 100% effective, and a single tick is now even more likely to kill a young dog.
The parallel I’m thinking of here is that too often people install antivirus software and then forget to be vigilant.

No antivirus or similar single product can ever give you 100% protection out there in the wild.

Malware attackers are relying on tricking people as anti-malware software becomes more sophisticated.
Phishing for example works mostly by tricking you into thinking that you are at a legitimate site.  The purpose of a phishing scam is to steal your identity – passwords, account details or credit card numbers.

Firefox (a web browser many people use instead of Internet Explorer) checks sites you are visiting against lists of known phishing and malware sites.  Google has also implemented a great tool for Firefox that alerts users that a site contains malware.

Even so, each person using the internet must stay vigilant.

People are busy, tired, distracted and under time pressures, and these factors often contribute to people clicking on links, opening attachments or clicking on OK when they should not have.
Microsoft Windows Vista has the best security to date of any Windows system, but if this decreases the vigilance of the user an attack is still going to happen with potentially catastrophic results.

Extra stuff for your MAC

Filed under: MAC, Software, malware — katrina @ 9:49 am

I had an interesting experience last week.

I had a word document that I had created and had been working on for a week or two.

I converted it to a pdf and sent it to someone using windows for their opinion and they sent back some suggestions for changes which I did.

I then converted to pdf again and sent to my business partner and co-director of BITTS who is using a Mac Book Air with no windows install.

He responded that his antivirus software had alerted him that there was a trojan virus attached.

Well that sparked off having me researching more on virus infection and the Mac and as a result I downloaded and installed iAntiVirus and ClamXAv.

The first run - ClamXAv -  found some infected emails in my junk mailbox that I had not opened as Mail had sent them straight to Junk, and of course I emptied my junk mail immediately.  It found no other infection, certainly none in the pdf I had emailed out, nor the actual email sitting in sent items.

The second run - iAntiVirus - found no infections.

In the meantime Les had all sorts of odd little things happening on his Mac and finally his antivirus declared he was clean.

So without any infection found in the pdf document and no infections apparently having been active on my Mac I simply sent him the file again.

No response from his antivirus this time!

What happened?

I’ve no idea and that’s the truth.

Whatever it was, it was a windows virus and not something that could affect the Mac, and I will take the plunge and say that I suspect that my partners antivirus was giving a false report as it is too odd that with no infections here and no one else reporting an infected mail out from me, that it was something on my machine.

But it is a timely reminder for me who was writing a column about Mac maintenance and the need to avoid becoming complacent about virus.  It’s weird sometimes how things like this can happen in an ironic fashion.

I used to keep Norton AV for Mac, but I decided not to continue when payment time came around and happened not to have installed any of the free programs when this all happened.

The main issue Mac users have is that they can ‘get’ a virus on their computer, but it can’t wreak it’s havoc or damage there, but it may be able to pass itself on to windows people you communicate with.  Then of course it can wreak it’s havoc.

Another common thing I hear said is: but if companies like Symantec make antivirus for Mac then it must be true that they can get infected, everyone else is lying to trick me.

Really all we are doing when we pay money for these programs is filtering out Windows virus threats so we don’t pass them back - a windows virus CANNOT infect and do harm to your Mac!

Below are a few links for you to investigate and think about what steps you might take for your own Mac.

Mac World article on buying a Mac

Digital Trends excellent article

Mac World article on Parrellels (the feature that lets you simultaneously use Windows and Leopard)

Mac World article on Mac Antivirus

Nortons AV for Mac

I do hope all this helps to dispel some of the myths and assist you to choose what path you should take with your Mac


MACs back in with new chip

Filed under: MAC, Software — katrina @ 9:16 am

Use of the Mac is becoming increasingly popular with the latest figures showing usage at 16%. The change over to the Intel chip last year has possibly been partly responsible for this rise as you can boot into Windows as well as into Leopard.
The price has also come down significantly so that you can purchase a Mac system for a similar price to a PC.
All computers need maintenance regularly and the tasks don’t vary greatly from a windows machine except that the Mac defragments itself without the user needing to do anything.
The main thing a Mac user needs to do is run software updates automatically and the system will run optimally.
Maintenance the user can do for their system includes:
Keep files named clearly and stored in folders so they are easy to manage.  Please note that if you use iPhoto to manage your photos, only rename them from iPhoto rather than from the finder.
If your disk is getting full you can archive files that you don’t need but want to keep.  This creates a small zip file containing your files.
Backing up is as important when using a Mac as any other system.
Leopard has an impressive backup feature called Time Machine that manages your backups for you and makes finding items in the backup a snap.  I have my Mac backing up every hour when I am working on important jobs.
Now the Mac is far less likely to get a virus, unlike Windows, but that doesn’t mean it is impossible.  In fact many Mac owners will run Anti Virus software mostly to ensure they don’t pass Windows viruses on that were unable to affect the Mac.  Still Mac users should beware of becoming complacent.

thinking windows

Filed under: Business Processes, Software — katrina @ 7:57 am

OK so those poor souls who are running a business with Windows operating systems need to really think carefully about maintenance of their system.

Don’t fob this off as not important - keeping a computer running properly and securely is extremely important!  Your business files are the crux of your business and an office that stops running because of system crashes is an office losing money!

Sure everyone needs to maintain their systems but with the threat issues related to Windows it becomes even more critical.

This is where it is important to be aware of what operating system you are running as there are significant differences particularly between Vista and earlier versions.  Vista has attempted to give more of a feel similar to the MAC and in the background there are now system tools automatically doing some of the tasks that you had to either do manually or ensure you turned on schedules for.

Next week I will be looking at the maintenance needs of the MAC so don’t lose heart or interest if you are not a Windows user, but keep coming back.

A lot of this is really just good old common sense once you know it.

But if you don’t know it, and you don’t know what you don’t know, then you simply need some clear pointers to get you wised up.

Fortunately Microsoft actually do supply quite a good quality and quantity of information on this side of things so I’m going to use their own info here.

WINDOWS XP

WINDOWS VISTA

Both these sites are a really good start in thinking about maintaining your computer system, but don’t forget that there is also a critical need for having up-to-date virus and malware software running.  These threats are still rampant and the internet and email are the main modes of transmission.  No business today that have computers are not using these tools, so don’t discount that everything will be ok, or that you don’t do much so it doesn’t matter.

If you run computers, run them properly, carefully and keep your business in the black!


Get into the swing of a routine

Filed under: Business Processes, Software — katrina @ 7:23 am

A computer is more than just a filing cabinet, many components make up a complete system..
Like vehicles and appliances, computers need a regular maintenance plan.
A large organisation may be fortunate enough to have staff dedicated purely monitoring and maintaining the IT needs of the business.
In smaller businesses the choice usually is to either out-source or try doing it yourself.
There are significant differences between the versions Windows regarding which inbuilt maintenance processes can be scheduled to run automatically or have to be carried out manually.
The internet is a fantastic resource to assist anyone carrying out computer maintenance.  A very important point to remember is to ensure that the information relates to the equipment and version of software that you have.
One of your most important daily routines should be to back up your files and have at least one verified copy in another location, just in case of the inevitable happening. Too often I hear about businesses that have a backup copy but later find out that it is corrupted and of no use after a disaster.
The minimum maintenance tasks you need to become familiar with and perform regularly are: ensure the anti virus program is enabled and up to date, removing unused programs, archiving old files, using disk cleanup tools to free up disk space, defragmenting your hard disk, ensure all software is up to date and the updates are scheduled for a time that doesn’t impede normal operations ie after hours. Regularly completing these maintenance tasks will lead to greatly improved performance. Other items such as modems and networking equipment (wired and wireless) may require a specialist to carryout checks for security breaches and performance issues.
It is critical that your business computers work optimally, therefore spending a little time and money on maintenance will deliver significant returns on your investment.

clean it up!

Filed under: Business Processes, Software — katrina @ 7:15 am

What happens if your desk becomes piled so high with papers that you have no clear space left?


What happens if the same thing happens with your computer?

There are a few practices that should be put in place when working with any kind of computer system and there are differences between the maintenance options and features different systems offer.
In a class discussion I ran recently, there were some excellent routine/process suggestions that have been on my mind since.

Sometimes a simple routine can totally revolutionise your business life.

Most business owners find it too easy to get caught up in the day to day stuff – phones ring, emails come in, people come in (or fail to come in), orders arrive, orders have to be placed – another day is over and you are leaving an hour later than you expected, again.

No wonder workspaces and computers become cluttered and clogged up.

This means it is even harder to get your work done efficiently the next day as you are already behind.

The really tricky bit is that many people don’t even notice that their computer is in this state, until something goes seriously wrong.  They “think” they have records of lots of stuff on there “somewhere.”

The thought of getting in and cleaning it all out is often too much for many people to seriously contemplate.
Some processes on how your file your work and the regular maintenance to keep in good working order can save you uncounted working hours.
The Windows machine is quite different to maintain compared to the Apple Mac.
Over the next couple of weeks I will look at how each of these types of machines should be looked after in their different ways, then talk about some general practices that should be followed regardless of what system you use.

Don’t do your business a disservice by neglecting good practice.
