Understanding Water Softeners for Well Water

Having well water comes with its own set of unique challenges, one of which is hard water. Hard water contains high levels of dissolved minerals like calcium and magnesium, which can cause a variety of problems in your home, from mineral buildup in pipes and appliances to dry skin and hair. Water softeners are specifically designed to address these issues by removing hardness minerals from your water supply.

Do I Need a Water Softener for My Well Water?

Whether or not you need a water softener for your well water depends on several factors, including:

  • The hardness level of your water: You can get your water tested by a professional or use a home test kit to determine the hardness level. Generally, water with a hardness level above 7 grains per gallon (gpg) is considered hard and can benefit from softening.
  • The problems you're experiencing: If you're noticing mineral buildup, soap scum, or other issues associated with hard water, then a softener can help.
  • Your personal preferences: Some people simply prefer the feel of soft water for showering, washing dishes, and other tasks.

Types of Water Softeners for Well Water

There are two main types of water softeners for well water:

  • Salt-based softeners: These are the most common type and use ion exchange to remove hardness minerals. They require regular regeneration with salt, which can be a maintenance burden for some users.
  • Salt-free softeners: These use various technologies, such as template-assisted crystallization (TAC) or magnetic fields, to reduce hardness. They don't require salt but may be less effective than salt-based softeners in some cases.

Choosing the Right Water Softener for Your Needs:

When choosing a water softener for your well water, consider the following factors:

  • Your water hardness level: This will determine the size and capacity of the softener you need.
  • Your water flow rate: Make sure the softener can handle the amount of water your home uses.
  • Your budget: Salt-based softeners are generally less expensive than salt-free models, but you'll need to factor in the cost of salt.
  • Your maintenance preferences: If you're not interested in regular maintenance, a salt-free softener may be a better option.

Additional Considerations for Well Water:

  • Iron and other contaminants: If your well water contains iron or other contaminants, you may need a combination water treatment system that includes a softener and an additional filter.
  • Professional installation: It's generally recommended to have a professional install your water softener to ensure it's properly sized and connected.

Benefits of Using a Water Softener for Well Water

  • Reduces mineral buildup: This can prevent damage to pipes, appliances, and fixtures.
  • Improves soap and detergent performance: Soft water allows soap and detergent to lather better, so you can use less and get better cleaning results.
  • Softer skin and hair: Soft water can help reduce dryness and irritation.
  • Longer lifespan for appliances: Soft water can help extend the life of your washing machine, dishwasher, and other water-using appliances.

Conclusion:

Water softeners can be a valuable investment for homeowners with well water. By considering your specific needs and water quality, you can choose the right softener to enjoy the benefits of soft water throughout your home.

How To Start | How To Become An Ethical Hacker

Are you tired of reading endless news stories about ethical hacking and not really knowing what that means? Let's change that!
This Post is for the people that:

  • Have No Experience With Cybersecurity (Ethical Hacking)
  • Have Limited Experience.
  • Those That Just Can't Get A Break


OK, let's dive into the post and suggest some ways that you can get ahead in Cybersecurity.
I receive many messages on how to become a hacker. "I'm a beginner in hacking, how should I start?" or "I want to be able to hack my friend's Facebook account" are some of the more frequent queries. Hacking is a skill. And you must remember that if you want to learn hacking solely for the fun of hacking into your friend's Facebook account or email, things will not work out for you. You should decide to learn hacking because of your fascination for technology and your desire to be an expert in computer systems. Its time to change the color of your hat 😀

 I've had my good share of Hats. Black, white or sometimes a blackish shade of grey. The darker it gets, the more fun you have.

If you have no experience don't worry. We ALL had to start somewhere, and we ALL needed help to get where we are today. No one is an island and no one is born with all the necessary skills. Period.OK, so you have zero experience and limited skills…my advice in this instance is that you teach yourself some absolute fundamentals.
Let's get this party started.
  •  What is hacking?
Hacking is identifying weakness and vulnerabilities of some system and gaining access with it.
Hacker gets unauthorized access by targeting system while ethical hacker have an official permission in a lawful and legitimate manner to assess the security posture of a target system(s)

 There's some types of hackers, a bit of "terminology".
White hat — ethical hacker.
Black hat — classical hacker, get unauthorized access.
Grey hat — person who gets unauthorized access but reveals the weaknesses to the company.
Script kiddie — person with no technical skills just used pre-made tools.
Hacktivist — person who hacks for some idea and leaves some messages. For example strike against copyright.
  •  Skills required to become ethical hacker.

Water Softener for Well Water: A Comprehensive Guide

What is a Water Softener and How Does it Work?

A water softener is a device that removes hardness from water, typically by exchanging calcium and magnesium ions for sodium ions. This process, known as ion exchange, occurs within a resin bed, which is composed of small, porous beads made of a material called ion-exchange resin.

Why is a Water Softener Needed for Well Water?

Well water often contains high levels of dissolved minerals, including calcium and magnesium, which cause hardness. Hard water can create several problems, such as:

  1. Scale Buildup: Hard water can cause scale buildup in pipes, appliances, and fixtures, reducing their efficiency and lifespan.
  2. Soap Scum: Hard water can make it difficult to create a lather with soap, resulting in soap scum buildup on surfaces.
  3. Dry Skin and Hair: Hard water can strip away natural oils from skin and hair, leading to dryness and irritation.
  4. Reduced Detergent Effectiveness: Hard water can reduce the effectiveness of detergents, making it harder to clean clothes and dishes.
How to Choose the Right Water Softener for Well Water:
  1. Water Hardness Level: The first step in choosing a water softener is to determine the hardness level of your well water. There are several ways to do this, including purchasing a water test kit or sending a sample of your water to a laboratory for analysis.
  2. Flow Rate: Consider the flow rate of your well water system when selecting a water softener. The flow rate is measured in gallons per minute (GPM) and determines the size of the water softener you need.
  3. Grain Capacity: The grain capacity of a water softener refers to its ability to remove hardness from water. The grain capacity is measured in kilograins (KGR) and determines how much hardness the water softener can remove before it needs to be regenerated.
  4. Type of Water Softener: There are two main types of water softeners: salt-based and salt-free. Salt-based water softeners use a process called ion exchange to remove hardness from water, while salt-free water softeners use a different process, such as template-assisted crystallization.
  5. Brand and Reputation: Consider the brand and reputation of the water softener manufacturer when making a purchase. Look for brands that are known for their quality, reliability, and customer service.
How to Install and Maintain a Water Softener for Well Water:
  1. Proper Installation: It is important to have a water softener installed by a qualified professional. Improper installation can lead to leaks, damage to the water softener, or ineffective water softening.
  2. Regular Regeneration: Water softeners need to be regenerated regularly to maintain their effectiveness. The frequency of regeneration depends on the hardness of your water and the size of the water softener.
  3. Salt Replenishment: Salt-based water softeners require regular replenishment of the salt supply. The frequency of replenishment depends on the hardness of your water and the size of the water softener.
  4. Maintenance: Water softeners should be inspected and maintained regularly to ensure proper operation and longevity. This may include cleaning the resin bed, checking for leaks, and replacing any worn or damaged parts.
Benefits of Using a Water Softener for Well Water:
  1. Improved Water Quality: Treated water has a reduced mineral content, improving the taste, smell, and appearance of the water.
  2. Reduced Scale Buildup: This can save you money by extending the lifespan of your appliances.
  3. Softer Skin and Hair: Softened water can help to improve the health of your skin and hair.
  4. More Effective Laundry and Dishwashing: Softened water can improve the performance of detergents and soaps.
  5. Increased Energy Efficiency: Softened water can help to improve the efficiency of water heaters and other appliances that use water.
Conclusion:

A water softener can be a valuable investment for well water users, providing numerous benefits and improving overall water quality. By choosing the right water softener and properly installing and maintaining it, you can enjoy the advantages of softened water throughout your home.

Reversing Pascal String Object

There are many goodware and malware developed in pascal, and we will see that the binary generated by the pascal compilers is fascinating, not only because the small and clean generated binaries, or the  clarity of the pascal code, but also the good performance. In Linux we have Lazarus which is a good free IDE like Delphi and Kylix the free pascal IDE for windows.

The program:

program strtest;

var
  cstr:  array[0..10] of char;
  s, s2:  ShortString;

begin
  cstr := 'hello world';
  s  := cstr;
  s2 := 'test';
  
  WriteLn(cstr + ' ' + s + ' ' + s2);
end.


We are going to compile it with freepascal and lazarus, and just the binary size differs a lot:

lazarus          242,176 btytes  845 functions
freepascal       32,256 bytes   233 functions
turbopascal      2,928 bytes     80 functions  (wow)

And surprisingly turbopascal binaries are extremely light.
Lets start with lazarus:




Logically it imports from user32.dll some display functions, it also import the kernel32.dll functions and suspiciously the string operations of oleaut32.dll 


And our starting point is a function called entry that calls the console initialization and retrieve some console configurations, and then start a labyrinth of function calls.



On functions 10000e8e0 there is the function that calls the main function.

I named execute_param2 because the second param is a function pointer that is gonna be executed without parameters, it sounds like main calling typical strategy.
And here we are, it's clearly the user code pascal main function.


What it seems is that function 100001800 returns an string object, then is called its constructor to initialize the string, then the string is passed to other functions that prints it to the screen.

This function executes the method 0x1c0 of the object until the byte 0x89 is a null byte.
What the hell is doing here?
First of all let's create the function main:


Simply right button create function:

After a bit of work on Ghidra here we have the main:


Note that the struct member so high like 0x1b0 are not created by default, we should import a .h file with an struct or class definition, and locate the constructor just on that position.

The mysterious function was printing byte a byte until null byte, the algorithm the compiler implemented in asm is not as optimized as turbopascal's.

In Windbg we can see the string object in eax after being created but before being initialized:












Just before executing the print function, the RCX parameter is the string object and it still identical:


Let's see the constructor code.
The constructor address can be guessed on static walking the reverse-cross-references to main, but I located it in debugging it in dynamic analysis.


The constructor reads only a pointer stored on the string object on the position 0x98.

And we have that the pointer at 0x98 is compared with the address of the literal, so now we know that this pointer points to the string.
The sentence *string_x98 = literal confirms it, and there is not memory copy, it only points reusing the literal.



Freepascal

The starting labyrinth is bigger than Lazarus so I had to begin the maze from the end, searching the string "hello world" and then finding the string references:


There are two ways to follow the references in Ghidra, one is [ctrl] + [shift] + F  but there is other trick which is simply clicking the green references texts on the disassembly.

At the beginning I doubted and put the name possible_main, but it's clearly the pascal user code main function.




The char array initialization Is converted by freepascal compiler to an runtime initialization using mov instructions.

Reducing the coverage on dynamic we arrive to the writeln function:


EAX helds  a pointer to a struct, and the member 0x24 performs the printing. In this cases the function can be tracked easily in dynamic executing the sample.

And lands at 0x004059b0 where we see the WriteFile, the stdout descriptor, the text and the size supplied by parameter.


there is an interesting logic of what happens if WriteFile() couldn't write all the bytes, but this is other scope.
Lets see how this functions is called  and how text and size are supplied to figure out the string object.



EBX helds the string object and there are two pointers, a pointer to the string on 0x18 and the length in 0x18, lets verify it on windbg.


And here we have the string object, 0x0000001e is the length, and 0x001de8a68 is the pointer.


Thanks @capi_x for the pascal samples.

One Reason Why InfoSec Sucked In The Past 20 Years - The "Security Tips" Myth

From time to time, I get disappointed how much effort and money is put into securing computers, networks, mobile phones, ... and yet in 2016 here we are, where not much has changed on the defensive side. There are many things I personally blame for this situation, and one of them is the security tips.

The goal of these security tips is that if the average user follows these easy to remember rules, their computer will be safe. Unfortunately, by the time people integrate these rules into their daily life, these rules either become outdated, or these rules were so oversimplified that it was never true in the first place. Some of these security tips might sound ridiculous to people in InfoSec nowadays, but this is exactly what people still remember because we told them so for years.

PDF is safe to open

This is an oldie. I think this started at the time of macro viruses. Still, people think opening a PDF from an untrusted source is safer than opening a Word file. For details why this is not true, check: https://www.cvedetails.com/vulnerability-list/vendor_id-53/product_id-497/Adobe-Acrobat-Reader.html
On an unrelated note, people still believe PDF is integrity protected because the content cannot be changed (compared to a Word document).

Java is secure

One of the best ones. Oracle started marketing Java as a safe language, where buffer overflows, format strings and pointer-based vulnerabilities are gone. Unfortunately, they forgot to tell the world that instead of "unsafe programs developed by others" they installed their unsafe program on 3 billion devices. 

Stay away from rogue websites and you will be safe

This is a very common belief I hear from average people. "I only visit some trusted news sites and social media, I never visit those shady sites." I have some bad news. At the time of malvertising and infected websites, you don't have to visit those shady sites anymore to get infected.

Don't use open WiFi

I have a very long explanation of why this makes no sense, see here. Actually, the whole recommendation makes no sense as people will connect to public WiFis, no matter what we (InfoSec) recommend.

The password policy nightmare

Actually, this topic has been covered by myself in two blog posts, see here and here. Long story short: use a password manager and 2-factor authentication wherever possible. Let the password manager choose the password for you. And last but not least, corporate password policy sux.

Sites with a padlock are safe

We tell people for years that the communication with HTTPS sites are safe, and you can be sure it is HTTPS by finding a randomly changing padlock icon somewhere next to the URL. What people hear is that sites with padlocks are safe. Whatever that means. The same goes for WiFi - a network with a padlock is safe.

Use Linux, it is free from malware

For years people told to Windows users that only if they would use Linux they won't have so much malware. Thanks to Android, now everyone in the world can enjoy malware on his/her Linux machine.

OSX is free from malware

It is true that there is significantly less malware on OSX than on Windows, but this is an "economical" question rather than a "security" one. The more people use OSX, the better target it will become. Some people even believe they are safe from phishing because they are using a Mac!

Updated AV + firewall makes me 100% safe

There is no such thing as 100% safe, and unfortunately, nowadays most malware is written for PROFIT, which means it can bypass these basic protections for days (or weeks, months, years). The more proactive protection is built into the product, the better!

How to backup data

Although this is one of the most important security tips which is not followed by people, my problem here is not the backup data advise, but how we as a community failed to provide easy to use ways to do that. Now that crypto-ransomware is a real threat to every Windows (and some OSX) users, even those people who have backups on their NAS can find their backups lost. The only hope is that at least OSX has Time Machine which is not targeted yet, and the only backup solution which really works.
The worst part is that we even created NAS devices which can be infected via worms ...

Disconnect your computer from the Internet when not used

There is no need to comment on this. Whoever recommends things like that, clearly has a problem.

Use (free) VPN to protect your anonimity

First of all. There is no such thing as free service. If it is free, you are the service. On another hand, a non-free VPN can introduce new vulnerablities, and they won't protect your anonymity. It replaces one ISP with another (your VPN provider). Even TOR cannot guarantee anonymity by itself, and VPNs are much worse.

The corporate "security tips" myth

"Luckily" these toxic security tips have infected the enterprise environment as well, not just the home users.

Use robots.txt to hide secret information on public websites

It is 2016 and somehow web developers still believe in this nonsense. And this is why this is usually the first to check on a website for penetration testers or attackers.

My password policy is safer than ever

As previously discussed, passwords are bad. Very bad. And they will stick with us for decades ...

Use WAF, IDS, IPS, Nextgen APT detection hibber-gibber and you will be safe

Companies should invest more in people and less into magic blinking devices.

Instead of shipping computers with bloatware, ship computers with exploit protection software
Teach people how to use a password safe
Teach people how to use 2FA
Teach people how to use common-sense

Conclusion

Computer security is complex, hard and the risks change every year. Is this our fault? Probably. But these kinds of security tips won't help us save the world.
