I used the non-commercial version of JHackGuard, but my website was hacked again and again.
I had to learn:
"If you pay peanuts, you get monkeys."
"If you buy cheaply you pay dearly."

First, we’d like to say that jHackGuard doesn’t have a paid version. It’s a free plugin designed to improve your site’s security.

As to your site being hacked over and over again, we’d advise you to get it checked by a professional and make sure that there are no backdoors left from previous hacking attempt.

Having a secure website is a combination of following good practices, having the proper software and keeping it up-to-date. Unfortunately, you can’t have all hacking threads neutralised by using only a single plugin.

Simple to install and configure, no problems at all.

Installed it on several 1.5. and 2.5 sites, and I was amazed how many attemps there are when I look at the log files.

Thanks for a great plugin.

Hello,

We are sorry that you decided not to use our plugin. We usually receive very positive feedback from people who have enabled it on their websites.

In regards to the promo emails that you have received from us - during the download of the extension we explicitly ask users for their permission to receive updates from us about our services and products. We have investigated the issue with the broken unsubscribe link and it turned out that during our recent website redesign, the unsubscribe form has stopped working. Our developers have fixed it immediately, and now it is working just fine. Thank you very much for reporting this! If you want, you can either try it again or send us an email at news'at'siteground.com and we will remove your address from the list manually.

As to our Chat support I can assure you that there are no bots working for us at the moment :) However, note that the best place to get a jHackGuard support in case you're not our customer is via the support link above which will redirect you to our forum. It is monitored and questions answered by our Joomla experts (and jHackGuard developers personally). We will be glad to help you there, just drop us a line with your request.

Used it for years for Joomla 1.5 ... and now using it for Joomla 1.7 to Joomla 2.5.

Earlier, I always got a lot of problems with my Joomla site. But since I am using this plugin, not a single attack more.

Thank you siteground team.

Hi,
It looks good, but after upgrading joomla and adding this plugin, my site was hacked - the index.php file was changed.
So it seems this isn't the best solution.
Owner's reply

Please post a thread in the jHackGuard support forum(you can access it via the Support button above). We will happy to investigate your case in details and make sure we add the necessary changes to protect Joomla sites against such attacks. If possible please make an archive of your hacked files and allow us access to it. All logs from that period you may have will be useful too.

We take our customers feedback seriously and look into every issue reported to us. We have just released a new plugin version based mostly on the feedback by our users.

After a recent hack 'defacement' of my site, I went on the hunt for a reliable anti-hack solution, this plugin seemed to fit the bill and was the right price FREE. So after careful study of other reviews and opinions I gave it a try. I have now installed it on 9 of my sites that were frequently attacked, and to date none of them have been defaced since. With regard to removing the backlink, just select disable on the 'Link back to SiteGround' option. Thanks for a great FREE plugin. Highly recommended.

First thanks for this good plugin.
But I cannot enable logging on my Sever.
Is there any possibility to change the storage to the folder named logs.
Because, if you host a server by 1&1Puretec, they are using "logs" as there folder. And the permittion can not be set to 755. So a error will show up with every login.
Owner's reply

Hello,

In the current version, you can only specify the name of the log file but not the directory it is saved in. We have already reported this request to the plugin developers and we will do our best to have this new functionality included in the next plugin version.

I uninstall a previous version of jHackGuard Joomla plugin, but the link to SiteGround remains in the page bottom. If I install the last version of the plugin for Joomla 1.5.x and configure for disable the link in the bottom, the links still remains.

I ask for solution in SiteGround, but they told me I must create an account with them. I think the plugin is a hook.

In new versions the link to SiteGround is optional, but there is not a visible solution for the problem of oldest versions.

I know is free, but make a warning please. The new version perhaps have an Excellent rating for me, but my vote right now is for the attitude of SiteGround Team.

I see a lot of similars non happy comments in forums, but no real solutions, even when SiteGround's members participate. In best cases they answer is: "Go to SiteGround.com and contact using chat"; I did it, and the solution of the operator was: "create an account with us". And if I don't want to? My site must have an eternal link to SiteGround, even when I uninstall your plugin? This is legal?

If some body have an effective solution let me know an for sure I change my words.
Owner's reply

Hello,

It seems that you are experiencing issues with some 3rd party caching extension. Once the plugin is removed there are NO links or other information that remains on your website. As for receiving support with using this plugin, our website chat isdefinitely not the best place, as our main business is web hosting and the live chat is operated by our web hosting Sales team. However, any jHackGuard user can receive timely assistamce (no matter if s/he uses our hosting services) by posting its request on the special forum category we have created for this purpose. You can access it either from the "Support" button above or directly through this link: http://forum.siteground.com/forumdisplay.php?f=55

Very well written plugin. I had issues removing the watermark (Link Back to SiteGround) in the previous version, however that has been taken care in the latest release. There is now an option under the configuration of the plugin "Link back to SiteGround" which can be set to On or Off which makes it easy to manage the link back shown in the home page without having the need to touch the code.

Thanks SiteGround. You Guys Rock.

Regards
Syed

Been using this on J1.5 and it was great, but now that i have moved over to 1.7 its a complete mess.

As brian mention, it filters out extremely common words, i have tried the latest 1.2.1 version and it has not sovlved the problem, we have a social network with public bloggers and no matter where you want to use the word union, front-end or back, user level irrespective it removes the work or that part of any word containing it.

Even tried posting it as my status in JomSocial and as a super admin it would not let the post succeed. They are completely delusional if they believe they have solved the problem.
Owner's reply

Hello,

We have tested the plugin and we can confirm that the version for Joomla 1.7 no longer filters in any way content added by users that have access to the administrative area. To make sure that the latest version of jHackGuard is used please completely remove your current instance of jHackGuard, download it anew from our website and install it.

As to the JomSocial component, it allows users without access to the administrative area to create and publish content to your website. This behavior triggers the jHackGuard security checks and if anything suspicious is found it will be blocked. Our plugin utilizes the same logic in both Joomla 1.5 and Joomla 1.7 versions. This means that posting "union" through a JomSocial component will be filtered in all Joomla versions. Note that the majority of the MySQL injections work using precisely this command to execute unwanted queries to your database. For example, if someone posts 'and1=1 UNION select * from jos_users' and your comment extension is not written securely, this will return everything in your jos_users table. Through this command if an attacker find such security hole he/she can execute literally every query he/she wants.

We also plan to develop further the plugin and converting it to a component that utilizes the new Joomla ACL system. This will allow each user better control over the security checks to be applied on his/her website.

I've seen some bad extensions but this one really takes the biscuit.

The extension is so badly coded that it tests for things without checking without checking the context

For example it is impossible to write an article about a trade union as the extension removes the word union

Or to write the word concatenate as it removes the characters concat

Or to write a basic tutorial about joomla as it removes common terms such as jos_users.

Removing any of these from your content is just plain stupid!!!!

Thank you for reporting these issues with jHackGuard in Twitter last week. We have tested and found that there was really a flaw in the jHackGuard version for Joomla 1.6 and 1.7, which was fixed and the new version of the plugin was uploaded yesterday.

Our plugin is originally designed to check whether the user submitting information to the site has admin privileges or not. By default only if the user has NO admin privileges we look for patterns for SQL injections and other hacking techniques and block posts containing such patterns in order to prevent the site from being hacked. Unfortunately, due to a slight modifications in the latest Joomla versions, the check whether an user has admin rights or not wasn't working correctly. This is why you were unable to post articles containing content that you've mentioned as your posts were block by mistake.

You can download the plugin again from our site and give it another try. I believe that you will find it useful and working as expecting to protect your site from hacking attempts. Of course any bug reporting or improvement suggestions are more than welcome!

I have made many Joomla website over the years. About 1 year ago some of the many sites I designed started getting hacked from the outside. I did some research and found the "jHackGuard" plug-in.

I have installed it now on 5 websites I have created and they are all secure. (or seem to be)

On my personal Joomla website I have tried several other Admin tools, so that in the future (If one of my clients get hacked) I have other things I can do to help them out. Thanks to all the programmers who make these Extensions for Joomla! (Non-Commercial)

Okay, I know that unless my site gets hacked I really don't know how well this works. However, with that understanding, it installed well, that is, after I disabled my "register global" in my php.ini file. I use Hostgator and they require it turned off thru the php.ini file. They tell you in the forums that you should have register globals disabled because, really, without it - any security add on is really useless. I believe them so mine is disabled! Anyway, thanks for the plugin, I'm trusting it will help keep my client's site safe (especially since it is going to be hosted on Siteground's server - the guys who wrote the plugin)
As far as the footer, just take it out of the plugin file. I didnt mess with the php code, just the html section that puts it in there.

Can't really rate this except to say that it caused my site to go offline with errors. I guess I'm not allowed to post the error message here but I did see that's it's a common problem in their forum. Apparently it's incompatible with something on my site. Too bad, I would have like to use it. Linkbacks is not something that would prevent me from not using an extension, they are too easy to remove. Some of you really should take some online HTML, CSS, and PHP courses, many of them are free and you'd never have to complain about linkbacks...just remove them!
