Email Password security tips

Here are some general security tips to keep your email account safe.

1. Use a unique password for your email that you do not use anywhere else. The reason for this is pretty simple. Most websites when you register on them ask you to give them your email address. If you give that website your email address AND you use the same password that you used on your email login, you've just given that website access to your email account. Most websites are probably trustworthy. But what happens if that website gets hacked and someone steals all your registration information? Now some hacker has your email login information. So ALWAYS use a unique password for your email account that you do not use anywhere else.

2. Do not use a simple password. A simple password would be one that's only a few characters long and/or consist of simple words. Most hackers are not sitting in front of a computer typing in one password at a time. They have tools to automate it. So if your password is very short or consists of simple words, they can use a dictionary to guess your password. The best passwords are at least 10-12 characters long. Longer is even better. And it's good if it contains a mixture of letters and numbers. Even better if it contains letters, numbers and punctuation characters like $#@!%. Most passwords are case sensitive, which means mypassword is not the same as myPassWord. So mixing up the casing of the letters is another very good method to make your password hard to guess. The best passwords combine all of this into something called a pass phrase. A password implies a single word. A pass phrase is a combination of words.
So rather then having 'password' as your password, you would have 'this is my password' as your password, or pass phrase. And if you combine it with the other suggestions it might look like '@thiS is mY 1 passworD!'

3. Pick security question/answers only you know. Many websites ask you to set up security questions that you can answer if you ever forget your password, or login from a strange computer. These security questions can turn into security holes. If you pick a very simple question ' what is my favorite color' and pick an equally simple answer 'blue', it wont take very long for someone to guess your security answers. The best thing to do is to pick questions that only you would know the answer to. However, many sites don't allow you to type your own question, you have to pick one of their questions. And their questions are often questions that other people know the answer to. Like what school you went to, the name of your spouse, your first job etc. Those are all questions other people have the answers to and in many cases even strangers can find the answers to them by doing a little google searching. For example, if you have a linkedin account,  your first job AND what schools you attended might be listed there. Your spouse might be listed on facebook or another social site.

So if you can't type in your own question, you can always give an answer that has nothing to do with the question or is completely made up. For example, if it asked what school you went to, you might say Startfleet Academy (although in my case my friends could guess I'd pick that answer). Or make up an answer that's completely random. Instead of Starfleet Academy, you could say apple pie. You just have to remember the answer you give. The key is to make sure it's an answer know one but you knows and no one could figure out.

4. Don't type your password into strange computers. It's basically the same as catching an STD. You don't know who else used that computer or where it's been. That computer could have a virus on it and as soon as you type in your password, it's recorded it and sent it off to some nefarious hacker who now has access to your account. This applies even to your friends computer, unless you are sure they are practicing safe computing.

How can you tell if you were hacked/if a friend was hacked?


5. Don't click strange links. If you get an email from a friend that has a ton of people it was sent to and all the email contains is a strange looking link, chances are they were hacked. I would contact your friend other then through their email and ask them if they sent it. If they did not, have them read this post and then change their passwords. I said passwords, plural, because once someone has access to your email account, they could potentially gain access to your other online accounts since many of them have a forgot password feature that will email you instructions on how to change your password. So the hacker gains access to your email account and looks through your emails to find an email from your bank. They then go to your bank's website. The first thing they'll try doing is using your email password in case you used the same password for your email as for your bank. If that doesn't work, then they'll try the forgot password feature and within a minute they could have access to your bank account. I'm sure they'll enjoy spending your money.

6. You wake up one morning and suddenly find a bunch of returned messages in your email. This is a good sign your account may have been hacked. This could be because the hacker logged into your email and then sent out an email to EVERYONE you ever emailed before. Or at least everyone in your address book. Some of those emails might have gone to addresses that don't exist anymore, or might have been caught by spam filters. That's why you'll suddenly have a bunch of returned messages in your email.

Many email websites allow you to check and see all the places you logged in from. if so, take a look and see if there's a login from somewhere you've never been, or at time you know you weren't online. If you find a strange login or have an inbox full of returned messages, it's time to change your passwords and contact your friends and let them know not to click any links that were sent.

Prevention


7. Use 2-step authentication. One of the features I like with gmail is something called 2 step authentication. It's basically using two passwords. You only are prompted for the 2nd password if you login from a new computer, or it's been 30 days since the last time you used the 2nd password.  If you have a smart phone, you download a small app to your phone and the app generates a new password for you every 30 seconds that you would type into your account the first time you log on from a new pc. That means even if a hacker gets your password, they still wont be able to log in because they wont have that random password generator. I still won't log in from a strange PC even with this if I can possibly avoid it. But at least if you do you know it'll still be almost impossible for them to get into your account. If you do login from a strange computer I would still change your password when you get home even with using the 2 step authentication.

I strongly encourage you to see if your email provider has 2-step authentication. If not, I would switch to someone who does.

Crashplan is untrustworthy - do not trust them with your back or data

I started using Crashplan for my backup needs back when Mozy switched away from doing an unlimited backup.  Initially I was very happy with their service.

However, since at least June of 2012 when I first noticed it, Crashplan has had horribly slow upload speeds. Many people are getting much less then 1mb uploads even though their internet connection supports speeds many times faster then that.

For anyone who frequently adds files to their backup set, this would make crashplan almost useless since you would never have a complete backup. You would always have files pending to be uploaded.

I myself could probably live with these speeds since I don't often add files to my backup. What I can not live with though is a company that lies. And crashplan lies. Their support has NOT ONCE responded to the thread I started here: https://crashplan.zendesk.com/entries/21660011 (they require you to register to view threads, probably to hide complaints from showing up in search engines - i'll post a complete copy at the end of this post).

That thread is almost 6 months old and has NEVER received a response from someone in support. It did however receive a response within a day when I finally got fed up and accused them of being incompetent or liars. Then a Mike Evangelist (listed as Chief Marketing officer according to his linkedin profile) suddenly stepped in and deleted my post accusing me of 'name calling'. I'm not sure what other conclusion you can come to when you have a problem that's ongoing for months and the only response you get from CP support, if they respond at all, is to tell you the internet is shared resource. Basically their excuse is that the internet is slow, not them. Apparently the internet has been slow, ONLY for crashplan customers, night or day, for months.

His idea of customer support was to offer me a refund. That's a pretty shoddy business model - no actual response to the problem itself, just someone who gets upset when you use harsh words about the lack of support and communication and then tells you to leave.

The only conclusion I can draw is that crashplan is either incompetent and doesn't know how to fix the problem or is otherwise incapable of doing so, or they are lying to me. I think it's both. I suspect they signed up too many users too fast and don't have the resources to support them all and are just hoping people wont notice.

As I said earlier, I could probably live with the slower upload speeds. But I will not do business with a company that treats their customers like this. They lie to their customers pretending there is no problem or pretending the problem is with you and not with them. They don't respond to complaints in their forum for MONTHS and then the only official response they finally give is to delete a post that calls them out for what they are - liars.

I don't know about you, but I would not do business with a company that is dishonest with you and treats their customers like idiots. Would you trust all your personal data with them? What's going to happen if their servers ever get hacked, do you think they'll actually let you know? Can you be sure you're data is really encrypted and safe on their server? And what happens if some day you need to download your data, how can you be sure you'll be able to get it? Or that it wont take months or years to download because of their poor service?

I apologize if this sounds like a rant, but I am angry. I think anyone would be angry if they are lied to for months on end. Because of this I've canceled my subscription to crashplan. Oh, and they are actually planning on raising their rates at the start of 2013. I'm going to use amazon glacier with cloudberry. Shockingly, the shared resource that is the internet seems to have no problem maxing out my upload speed when uploading to amazon. And it'll cost me less then what crashplan charges.

Edit: I've been using cloudberry in conjunction with amazon glacier for several weeks now without a single slow down. And it's only costing me $2/mo. To be fair, it looks as though the issue with crashplan has been resolved, at least the technical issue has. The customer service/honesty issue though has not. Crashplan only once admitted to there being any problem and it was a rather vague message along the lines of 'some' customers report problems and 'they are looking into it'. No explanation as to what the problem was. No explanation as to what they did to fix it. No sort of apology. I still don't trust them.

Edit 2: It loosk like CP might still be lying to their customers. Someone who just signed up with CP starts off getting 6mbps uploads but then quickly drops down to 250-300kbps. When they contacted CP support, this is what they were told:
I looked over your backup logs from the past few days and it looks like everything is going exceptionally well. 200-300 KBps sustained transfer rates are normal for most people and are common when the CrashPlan Client is backing up media files or other large chunks of data (applications come to mind). Those types of data don't compress well and therefore have to be sent in their entirety versus smaller chunks that have already been efficiently indexed by the CrashPlan Client.
That's the first time I've heard that not being able to compress file means it'll download MUCH slower then your maximum internet connection. The support rep went on to say turning off data de-duplication might speed up the upload. Which I assume is also either a lie or an indication their system is poorly made if data de-duplication means a 20x reduction in upload speeds.

Edit 3: For anyone still using crashplan and having problems, you might want to take a look at this blog post. He greatly sped up his upload speeds by disabling the deduplication function in crashplan's client.

Is Time-Warner cable scaming people?

I'm really getting tired of what I consider to be deceptive advertising with cable companies and the internet service they provide people. Used to be when they said you would get 'up to' a certain speed, it was an honest statement since you don't always get the maximum speed of your internet connection due to technical issues beyond their control.

Now 'up to' basically means they can give you whatever speed they want.

Here is an ad on one of the TW portal website advertising their internet packages:
TURBO INTERNET SPEEDS UP TO 20Mbps

but when you scroll down on the same page, it says:
Download Speed: Up to 10 Mbps

Hmm, up to 20mb and up to 10mb. This would be like buying a car where it says the MPG is 15 or maybe it's 30.

But it gets worse. I used their online chat to ask them about this. And they told me that the up to 10mb is a mistake, that I would really get 20mb. They told me this TWICE. Because I asked before I signed up, and then I asked again after I signed up for their service and discovered I was NOT getting 20mb, I was getting 10. Lo and behold when I called, I'm now told I have to pay an additional $10 to get 20mb.

Not only does it appear as though they are lying, but I think they are actually stealing your money. Because they offer a standard internet of 'up to' 10mb for $34.95 and then the turbo of up to 20 but really up to 10 for $44.95. So I really have no idea what extra you are getting for the extra $10 upgrading from the standard to the turbo, since it looks as though you really get the same speeds from both. Unless when they say 'up to' 10mb on the standard package, that really means you get 5mb.

I'm attaching an image of the chat convo showing the rep confirming that the turbo package should be 20mb.

AddToRun - add any program to the windows run screen

http://sourceforge.net/projects/addtorun/

A cool little program called AddToRun will let you specify any program you want with any name you want, and add it to the run menu (windows key + R). If you don't want to clutter up your desktop with shortcuts and don't want to dig through the start menu, this could be a convenient little tool to have. All you do is pick the program you want to run and give it a name. Then you can open the run menu (windows key +R), type in the name you gave the program and hit enter. And viola, you're program is running.

Some general comments on backups

Given my last post about mozy doing away with their unlimited plan, and seeing all the reactions from people, some of which seemed to be in a panic at the thought of possibly not having a full complete backup for a few weeks, I thought it would be good to make a few suggestions about backing up data.

The first thing to realize is your backup is exactly what it says - a backup. It should be a secondary copy of your data, not your primary storage. Forgive my nerd analogy (you did read the title of this blog didn't you?) but it's like being on the USS Enterprise while fighting the Romulans. Captain Kirk doesn't use the backup systems first, he uses the primary systems. He only asks Scotty to engage the backup's when the primaries are in trouble.

That's what your online backup should be like. They should mainly just be used for when your primary data storage - your hard drive - is in trouble. So if your online backup goes away, it shouldn't be cause for panic. Because your primary system should still be in relatively good shape and the chances of the primary going down while the backup is down should be pretty small.

The thing to keep in mind here is making sure your primary is always in relatively good shape. There's a few simple things you can do to ensure that.


  1. Run a disk monitoring program in the background to keep tabs on your hard drive. A very basic, and free program, is HDD Health from panterasoft. It'll monitor your drives and let you know if they report any problems.
  2. If you want to be even more proactive, you can schedule windows to run a chkdsk every week or month. You can either schedule this as a task in windows, or you can run it yourself. You have a few choices as to how you want to run the command, as it can drastically effect how long it takes to run the check, and also whether or not you can use your PC while the check is running. You can run it as chkdsk c: /F /R /X. replace c: with whatever drive you want to check. This command will take the longest and possibly require you to reboot the pc and wait for it to finish before you can use your PC again. Having to reboot is almost a certainty if you are going to check drive C.  If you want to speed things up a bit, leave off /R, which does a more intensive scan of the disk looking for bad sectors on the disk. If chkdsk starts reporting bad sectors, it's time to replace the hard disk. You can look up the warranty on the hard drive to see if it's still covered.
  3. The other suggestion I have is to replace your hard drive once it's 2 years old. Hard drives are pretty reliable - i can't remember the last time I had one fail. But if you replace them every 2 years or so, you are even less likely to see a failure. Given how cheap HD's are (and they keep getting cheaper), you'll more then likely be able to be a hard drive twice as big as the one you are replacing, for less then it originally cost you. So not only will you be ensuring the reliability of your data storage, but you'll also get more space out of it. 
  4. If you replace your hard drives like I suggest, you can then use those hard drives as backups, in addition to any online backups. You can buy an external enclosure for the drive on newegg or amazon for $20 or so. 
One thing to remember if you replace your drives and you are not going to keep them or re-use them - make sure you wipe all the data on them, especially if you plan on selling them or giving them away to anyone else. You can use Eraser to securely delete the data from your drives. It's also free.

And for some more free and useful sofware, check out my post about gparted, which you can use to partition those new hard drives and copy data from one drive to another.

One last suggestion when it comes to replacing hard drives - keep your original drive on hand for at least a week or two before you erase it or do anything else to it. The most likely time for a new hard drive to fail is right when you first start using it, if there's was any sort of defect to it. Otherwise, any decent hard drive will most likely last you several years.
