WordPress Brute Force Attacks on non-WordPress Sites

December 1, 2017 // Posted in Computer Tips, General, Main, Tips and Tricks (Tags: , , , , , , , , , , , , , , , , , , , , , , , , , , ) |  No Comments

There are more and more would-be hackers out there that are trying to attack WordPress Sites via a brute force attack on the wp-login.php file that is used on worpress sites to log in to the site.

The problem is that they do not know what are WordPress Sites and what are not so they try connecting to a wp-login.php file on almost every site. This can lead to hundreds of attempts on your non-wordpress by these hackers trying to find a wp-login.php file on your server. Check your server log and you will see all these attempts.

Now if as many people as possible added a wp-login.php to their non-wordpress site re-directing any call to that page back to the IP address that attempted to find it, then these idiots would perform a DOS attack on their own PC,
and stop them sending any more requests.

Here’s how to do it:

Create a file called wp-login.php in your non-wordpress site’s root folder with the following text in it (Your server must be php enabled):

 

 

 

 

Let’s hit back at these idiots together.

My Experience of Windows 10 – Part 2

August 8, 2015 // Posted in Computer Tips, General, Main (Tags: , , , , , , , , , , , , , , , , , , , , , ) |  No Comments

 Logging Into Windows 10, Updates and Memory

One thing I do not like about Windows 10, is that many functions require you to be logged into windows using an online Microsoft Account.

  1. I do not want to log in to windows using an Internet based Account.
  2. I do NOT want my personal data stored on a ‘Cloud’ based server.
  3. What happens if it is set to an online account to login and there is no Internet connection.
  4. Why can’t it just log in to the online account just to use that function such as Cortana, which has to have login via the online account?
  5. So Cortana is useless if you have no Internet connection?
  6. There are too many security issues logging in via an online account.
  7. I prefer to log in locally where my data is secure.

Windows 10 is also very memory hungry compared to Win 7, and even with my 4GB USB Ramdisk, is constantly buffering memory to a hard disk cache and has made some apps very slow because of this.

Windows 10 did an update Friday without asking, and I did a reboot of the machine, (that’s how I noticed it was doing something), there was no information that it was happening and on shutdown the screen went black although the hard disk was going crazy, so it was doing something. I left it for 3 hours and the hard drive had stopped being used but the screen was still black, and took a chance and switched off the machine and back on, then I got an opening message ‘Windows is configuring Updates 10%..’ etc and after another hours or so I got the welcome screen. I checked the windows update area and it says all updates were successful.

Not as clean and informative as Win 7.

Win7 – 2 ways to stop some of the hangs

September 15, 2014 // Posted in Computer Tips, Tips and Tricks (Tags: , , , , , , , , , , , , , , , , , , , , , , ) |  1 Comment

win7sDo you get hangs in Win 7 and sometimes cannot open programs or click on menu items?

Here is how to fix issues from two sources:

1. 16 Bit Programs – “16 bit programs in Win7?”, I hear you say. Yes believe it or not Windows 7 has several programs that run in 16 Bit mode, particularly some of the message pop-ups used by the system and UAC (User Access Control).

The pop-up from UAC, you know, the one that comes up to say “Do you want to let this program …….”, this often hangs and the program selected doesn’t load, and if you look in Task Manager you will see one or more copies of consent.exe (used by UAC) running but doing nothing, occasionally you may get a message to say ‘Too many 16 Bit programs are running’.

I too, was amazed when I discovered Win7 still used 16 Bit programs, I thought they all disappeared with Windows 98, or at least XP, but no Win 7 still uses them.

Because of that the 16Bit programs rely on the files and buffers settings in the config.sys file (remember that from the Windows98 and XP days). In many installations you will not find a config.sys file in the root folder, or there may be one that is set to hidden and system so you don’t see it in file explorer.

Let’s get back to fixing the hanging by UAC and the not being able to click buttons etc.

Create a new text file in notepad or the like and add the following two lines:

FILES=120
BUFFERS=1000

Then save the file with the name config.sys to your desktop.

Copy the file on the desktop and then in my computer open the root folder on drive C and paste the file.  You may get an “access denied” message.

If this happens you may want to view all hidden and system files to see if config.sys exists, if it does view it in notepad and you may see some text in it, but most likely it will either be empty or just contain FILES=20. If there is other text in there copy it and paste it into the config.sys file you just created on your desktop after the text you added, (remove the FILES=20 and leave the FILES=120 you added) and save the file.

Copy your file again and then select Start > All Programs > Accessories, right click Windows Explorer and select ‘Run As Administrator’ say Yes to the prompt. Browse to the root folder on C and paste the file you copied, you may get a ‘File exists overwrite?” this time say yes to overwrite and you new config.sys file will be in place.

Re-Boot your PC and you should no longer get the hangs when you start a program.

2. AVG Anti-virus and Constant Disk access and high disk queues in resource manager – If you are running AVG Internet Security 2014, you may have noticed that most of the time your hard disk in use light is permanently on and programs become very slow to respond and open or save files. Folders too are slow to open and icons or previews take ages to appear.

I have narrowed this down to AVG antivirus, and have found that after about 3 months following installation, something goes awry in AVG, and it starts constantly accessing the hard drive (Even when scans are not running or the PC is idle), so your hard drive is working it’s socks off and has to queue access by other programs whilst it waits for a break in AVG’s access, this makes your other programs slow and puts excessive load and wear on your hard drive which can lead to hard disk failure, not something you really want.

Here’s my fix, and it works every time for me. (make sure you have your license key ready as you will need it).

  • Download the AVG Full Installer (not the on-line installer) you can get it here http://www.avg.com/ww-en/download
  • Uninstall AVG from Control Panel > Add/Remove Programs.
  • Reboot your PC
  • Install AVG from the file you downloaded.
  • Wait for the updates to install or if they don’t start automatically, Choose Check for Updates.
  • When you see the AVG is up to date, reboot your PC.
  • Next time you use your PC once Win7 has loaded everything and settled down, watch the hard drive light, It hardly ever comes on except when loading a program, saving, or a quick flash every now and again.
  • Your hard drive will now last much longer than it would have done, and is less likely to fail.

Hope you find these useful

regards

Warning – Do Not Install Winzip Driver Updater

June 27, 2014 // Posted in Computer Tips, General, Main (Tags: , , , , , , , , , , , , , , ) |  No Comments

I received an email today from WinZip asking me to download FREE their driver updater program.

Being a winzip user for many years I thought I would give it a try from what I believed to be a reputable company.

However, I soon found out that they are not as reputable as I thought.

Why? I hear you ask.

1. The download was from their own site, and following the install AVG reported that one of the files in the installation pack was Malware that installs an adware program on your PC called MalSign.Systweak.44F, AVG soon fixed and removed the malware. This is not good from what should be a trustworthy supplier.

2. I ran the program to see what drivers could be out of date, The Winzip Driver Updater reported that all 23 drivers were out of date and needed updating, this seemed a little strange as my PC is relatively new and has only had all drivers installed in the past 8-9 months. I thought I would try updating one of the drivers so I could check the version etc., but I could not as the program said I had to pay for a ‘Full’ version to update any out of date drivers. I therefore decided to uninstall the program as I wasn’t going to pay for software that wanted to update all my drivers.

Once I uninstalled it, I tried windows update to see if they found any drivers out of date : Result – No drivers out of date.

Then I tried AVG’s PC Tune Up and guess what : RESULT – ALL Drivers are up to date.

Then I tried ASC’s (Advance System Care) Driver Booster and again guess what: RESULT – You have the latest drivers – no updates needed.

So it is clear to me that Winzip send you a ‘FREE’ download of a program that no matter what drivers you have, say they are all out of date just to get you to buy a version that allegedly updates those ‘out of date’ drivers’.

This is clearly a scam and not what you would expect from what seems to be a reputable company. They clearly are NOT reputable and this type of practice should be able to be punished in law some way, as it is misleading, makes false claims and  promises and is in my opinion,  fruadulant.

You have been warned – don’t get caught out. Use AVG Pc Tune Up or ASC Driver Booster (FREE) instead.

SEO Principles

May 24, 2014 // Posted in General, Main, Tips and Tricks (Tags: , , , , , , , , , , , , , , , , , , , , , , , , ) |  No Comments

Google

Google

Search Engine Optimisation is key to your site being found on the Internet.

SEO is your way of improving your website’s ranking in Google, Yahoo, and Bing. The more time and possibly money (if employing an external management  company) you spend on SEO, the more chance you will have of being the first search result listed by Google – which is the ultimate goal of any website and to be easily found by your potential customers.

The simplest technique is by altering the text, or ‘content’ on your website. To do this you must first understand your website’s target audience, who are they and what words will they type into Google when they are looking for this particular service or product?  There are of course many possibilities, and it is important to investigate those options and compile a list of your best appropriate keywords and phrases.

Once your keywords and phrases have been researched, your content can then be re-structured effectively so that it is ‘optimized’ and SEO friendly. You can have professional help with this, so talk to an SEO specialist company about what they would recommend. Other important actions include linking, (both internally – from your own site, and externally – other websites providing good linksto yours preferably from PR3 or higher sites) and implementing meta-tags, sub-headings, and website descriptions on all of your web pages. Content is king, so your success will be determined by the quality and relevance of your page content.

Important SEO principles  like ‘Black Hat’ and ‘White Hat’ SEO strategies. These two are very different  and it helps to understand the differences between them before talking to an SEO company about tactics for your website so you can make the right decisions.

‘White Hat’ SEO companies will use or recommend good design, good relevant content and appropriate linking. These will achieve longer lasting results and ranking.

‘Black Hat’ SEO companies, on the other hand will use underhand and inappropriate tactics to get fast results but at the expense of long term strategies and a sustainable website. They will hide bulk keyword text by using a background colour the same as the text so the text doesn’t display, or use font-colours to do the same or very small font sixes so that the text is not readable by humans. This will result in an immediate increase in ranking initially in some cases, but it won’t be very long before the search engines start imposing penalties on those sites and may even remove them from their search results completely.

So if you choose to use an external SEO company, be aware of these two types of SEO companies and ensure you choose the right one.

Keep up to date with what search engines are considering when ranking web site pages and adjust your content accordingly regularly to keep your site high in the rankings.

Also make sure you re-submit your site map to search engines regularly, and every time you make major changes to your site to keep your search results accurate and not link to now non-existing pages or content.

 

 

How to speed up a slow PC

May 24, 2013 // Posted in Computer Tips (Tags: , , , , , , , , , , , , , , , , , , , , , , , , , , ) |  No Comments

Slow PC?

Slow PC?

We have all had the problem that as your PC gets older and you install more and more programs your PC gets slower and slower. So what can you do to speed it up again? Here are five things that you can do:

De-fragment
This goes without saying, it is an essential regular maintenance job, however, I am surprised at how few people regularly do this if you ask them. Do You do this regularly? — Once a month is a good interval. It doesn’t matter which Windows OS you use, make sure you either manually de-fragment or set the machine up to automatically de-fragment at least once a month. When your PC’s files get very fragmented, they suffer serious performance issues. The built-in Windows de-fragmenter works just fine, but if you are looking for something a little better, there are many Free and Commercial products available

Clean up the hard drive
Have you ever filled up a hard drive? If this hard drive contains both your OS and your data files, your machine is going to die! This is often a major cause of slow running PC’s. You need at least 10-15% free on your hard drive for your PC to work, creating temporary working files. If  you haven’t got at least 20% free space, I would recommend you to start a clean up. The built in Windows Disk Clean Up utility quickly clears out all temp files for you, in various categories such as Internet Temporary Files, temporary download files, windows temp directory and more. Access it by right clicking the drive in MyComputer and click Tools > Disk Clean Up. Once you’ve done that, check your pictures, music and videos, as these are usually quite large files. Delete the ones you no longer need or copy them to an external drive or CD/DVD’s. Then check all your document files, delete those no longer needed and back up those you want to archive to another drive or DVD/CD. Once you have sorted those out, you can remove old Restore Points and Shadow copies (from the System Restore Utility) .Then check your installed programs, Do you need them all? There is probably some that you haven’t used for years, get rid of them using the Add/Remove Programs in Control Panel. After you have done all this Empty the re-cycle bin, and check your Drive Space again. Right click the drive in MyComputer and click properties.

Now it’s time to clean up the registry
Errors in the registry cause major slowing down of the PC, and can cause it to stop altogether. Modifying the registry is not something the novice or inexperienced user should attempt on their own, as incorrect changes to the registry can prevent your computer from even starting up. Before you make any modifications to the registry, either manually or using a professional tool, ALWAYS backup the registry first, then you can always restore it if something goes wrong. There are many software tools available, some free and some commercial. Most of them will find many errors in your registry, it’s not always something you’ve done, over time removing programs, upgrades and driver changes will leave remnants in the registry that should not be there. Run a registry fix tool and let it fix the errors it finds. Reboot to confirm your PC still works, (Most registry fixes will make a backup of anything they change, so that you can restore them in safe mode if something goes wrong, but that doesn’t happen very often if you pick a good tool.) After the re-boot run the registry fix again, as some more errors will be found, that do not become apparent until some of the first ones removed have taken effect. Re-boot again and Run the tool again, repeat the process until no errors are found.

Remove spyware/malware
If you are using Windows you MUST have an anti-malware program installed or your machine is guaranteed to get infected with spyware, which will gradually make your PC slower and slower, not to mention the potential privacy and security issues. Malwarebytes is good for this, although most anti-virus packages have anti-malware included, they do not always find all of it. Malwarebytes, is good and there are free and commercial versions available. I have found, that this usually finds anything that my anti-virus package misses (I’ve tried various anti-virus packages and Mawarebytes always finds something that each one of them didn’t). Get free program updates regularly and run it at least once a week. You can even trigger it to start at a specific time and day each week using the Windows Scheduled Tasks facility.

Check the hard drive for errors
After long periods of use the hard drive develops ‘Bad Sectors’, fragments of files get left behind in the indexes and other information in the file descriptors etc. can become corrupt. To fix it, you’ll need to check the drive for errors. Right click the drive in MyComputer and click Properties > Tools > Check Now >  Check the options to Automatically fix file system errors and also to scan and attempt recovery of bad sectors, then click start. If this is your Windows drive, or contains files that windows needs to operate (e.g.Swap file, system files and some drivers), you will be told that Windows needs exclusive access to this drive, so cannot perform the check now, and then asks you if you want to schedule the check when Windows next starts. Click Yes and reboot. The Disk check will start before windows does when you restart. This may take some time as it will check every piece of the drive surface, every file,folder, descriptor table etc. You can also get third party disk checkers, but the built in windows one seems to work just fine.
