Credit/Debit cards fraud – A solution? – How to protect yourself

1st of all I have been almost a victim to 2 fraud attempts in my 17 years in UAE. The 1st was from the US while the 2nd was from UAE. Both affected my UAE issued credit cards.

The 1st fraud attempt took place in Jan 2020. It was a result of me ignoring common sense pure and simple. When we were visiting New York, I visited a gas station in Staten Island which clearly looked dodgy but the car was low on fuel so I ignored common sense. The gas machine was asking for CCV/PIN so I put the PIN a couple of times and when it didn’t work. I then decided to go visit another gas station thinking that one was not working properly. Later, thank God, I discovered I was putting the wrong PIN. This incident resulted in a thief who successfully copied my credit card info but had the wrong PIN/CCV. As a result, when the thief tried to pay with my card online, the payment was rejected due to wrong CCV. I got a SMS of the rejected payment due to wrong CCV and of course called my bank and changed the credit card.

The 2nd fraud attempt took place in May 2023 when someone at 1 AM decided to use my credit card and buy something worth 47AED from a website in the US. The payment went through without OTP so that thief decided to add my credit card to his/her UAE Amazon account and use it to pay for something worth nearly a 1000 AED. I was saved by Amazon who rejected the payment. I woke up on a call from the bank’s credit card security team at 1 AM asking me if I make the transaction as Amazon flagged it fraudant.

The “thief” most likely got his/her hands on the credit card information from a security breach at one of online stores which saved my card information including the CCV without my consent or even alerting me that they are doing so.

So, the steps below does not offer 100% protection but they will make it harder and harder for you to suffer from a fraud transaction.

One last thing, protection and security walk hand by hand with inconvenience. Both have a price which you should be aware of (as in loss of credit card benefits for example) and ready to pay.

  1. Setup credit card spending limits. All banks now offer monthly and even daily spending limits which can be configured through their apps on your phone. For example, ADCB allows their customers to configure both daily and monthly spending limits while HSBC on the other hand allow their customers to only configure monthly spending limits for each of their credit cards. So, use this feature according to your needs and your panic level. For example, I have my ADCB cards set to 500 AED daily and 5000 monthly while my HSBC cards are setup to 1000 AED monthly. Then I adjust those limits accordingly if I need to exceed them and then revert them back to their old values once I am done.
    • The good thing is that you get to keep all the benefits offered by the credit card
    • The bad thing is the inconvenience this causes if you go to pay something and discover the you need to adjust the limit.
  2. Consider getting and using one of the prepaid credit cards which is topped up depending on how much you need. For example, Al Ansari Exchange offer such a card and you can top it up via a bank transfer using online banking from your phone. This is similar in a way to setting spend limits on your credit cards
    • The good thing is if you suffer any fraud transaction(s) then only what you have in the card is lost without any further loss.
    • The bad things are
      • The inconvenience this causes if you get to pay something and discover the you need to top up the card.
      • You lose all of your credit card benefits (cashback, airmiles, discounts,….)
  3. Consider using contactless payment solutions (Google Pay, Apple Pay, Samsung Pay) which hides your credit card details from merchants. They generate unique tokens (think of it as masked credit card numbers) to be used for each single transaction and can not be used more than once.
    • The good thing is you do not need to carry your credit cards with you
    • The bad things are
      • Now you need to make sure your login credentials to such payment solutions are secure. To mitigate this risk, consider enabling MFA via either SMS or an authenticator app on your phone to login to such portals to make it much harder to gain access even if your username/password were compromised.
      • The potential loss of credit card benefits (i.e cashback credit cards). You need to check with your bank if using these methods to pay your bills will cause any loss in benefits.
  4. Stop using your debit card for any purchases especially online ones. Debit cards have direct access to your bank accounts. Using them is just a BAD idea waiting to happen.
  5. Use RFID-blocking wallet which can help protect you against identity theft and fraud that might arise from electronic pickpocketing.
  6. VPNs are used widely in UAE. Avoid using “Free” VPN apps on your phone. Do not try to login to your banking app while those “free” VPNs are running and connected. If you need a VPN then get a paid service where you can be sure some level of security is there.
    • If VPN is a must for you then I would suggest to consider either PureVPN or Hotspot Shield and I still would advise against login to online banking while using those VPNs.

Always remember that Humans are the weakest link in any security system. If you take all the above-mentioned precautions but you are using pirated software or Operating System on your computer/tablet/phone then you are just asking to be hacked. The same applies if you are using a jailbroken iPhone or an Android phone that was tampered with. It is no longer a question of if but a question of when.

Make sure to use original software and Operating System on your devices. Make sure you invest in your device’s security. I would suggest you buy Norton 360 for both computers and tablets/phones. There is a Norton 360 10-device license for 70$ annually (60$ for the 1st year). Though this may sound expensive to some, I can assure you it is worth every benny if configured properly on all your devices.

Use common sense and do not open/respond any messages or open any links that you receive on SMSs even if you are actually expecting a “package”. If you are expecting something, then get the carrier phone number from their website and call them personally. Configure WhatsApp not to download any media automatically to your phone.

Make it harder and too much trouble for a thief to robe you even if it causes inconvenience to you. It is all about tradeoffs. But I would rather suffer some inconvenience, which I can mitigate, rather than suffering a fraudant transaction that takes forever to solve.

Credit/Debit cards fraud – The Nightmare – How does it happen

Please understand that there is no magic wand by which credit/debit card information can be obtained by anyone. Anyone preforming credit/debit card fraud must have your card’s data by using one of the below 3 main methods

  • Method 1: A leak from inside the entity issuing the card
  • Method 2: A leak from your computer/tablet/phone
  • Method 3: A leak from you personally

To be a victim of credit/debit cards fraud then one of the above mentioned must happen.

Method 1

In method 1, to be fair, a leak from inside the financial entity issuing the card is very difficult but not impossible. People do not know that though the bank’s call center staff know their security questions, those with access to all other details of credit/debit card sensitive information (PIN, CVV,….) are very few and they can sometimes be counted on one hand even in some big banks. Such leaks are very rare because the identity of the leaker will be found out easily in a short time.

Most leaks are a result of either the 2nd or 3rd methods on which I will go into details below.

Method 2

In method 2, some kind of software (aka trojan horse) gets installed on your device and it is later used to transmit your keyboard actions to whoever is controlling it. These kinds of software depend on you using either pirated OS or application or has misconfigured some of the security settings on the device. They depend on fooling you enough to accept and open something simple as a word document or a PDF file or a to open a link. If the device in question is secured, then these attempts will result in many warning messages and popups alerting you that something is trying to change some settings on your device which should be enough for you to take action and stop it.

This method however is where the vast majority of leaks take place in UAE mainly because a lot of people buy and use 2nd hand phones/tablets which could have been previously hacked. The same applies to computers using pirated OS and/or applications or if the security settings on your device are turned off. In addition, very few invest in securing their devices further by using powerful antiviruses and not the free ones which offers basic levels of protection.

Method 3

Method 3 describes itself. It is a leak from you personally. It happens when people ignore common sense. For example, people handing over their credit/debit cards along with PINs to others in order to process their payments. An example of this is when people hand over gas station workers their cards and provide them with the PIN to pay on their behalf. I have seen that happens countless times either at gas stations or at groceries stores. Another example would be when people hand over their cards to their kids and give them the PIN numbers! A child has no grasp of the dangers surrounding that plastic card and can be fooled much easily than you.

Credit/Debit cards fraud – The Ugly Truth – Why does it happen

Suffering from fraud is ugly and painful. Banks in UAE take forever to investigate cases and resolve them. In most cases, the full amount is never retrieved. Let alone banks force victims to pay the full bill till the issue is “investigated”. Victims on the hand have to wait for up to 90 days or more to get anything back.

So why fraud happens? Well, it is not rocket science. The most important 5 reasons as to why fraud happens in UAE are

  • Privacy and data protection is virtually nonexistence in UAE. There are no PCI/DSS style laws in UAE forcing merchants to encrypt their databases. The Central Bank in its notice dated 21 May 2019 ((CBUAE/BSD/C/2019/2094)) mandated all Financial Institutions operating in the Cards payment ecosystem to comply with PCI DSS but there is nothing for merchants to force them to do the same.
  • There is no law preventing merchants from keeping your credit/debit card information without your consent.
  • For the sake of easy, quick financial transactions and to save costs most bank’s payment gateways do not do basic security checks to minimize the chances of fraud transactions if the payment is below a certain value.
  • The vast majority of online merchants in UAE are very greedy and very cheap. Most of them use very powerful platforms to build their online stores BUT they fail miserably, either purposely or to just save costs, in configuring their security properly. So, it is not a question of if a disaster happens and rather it is when a disaster happens and a security breach take place as in the incident that affected Careem customers several years ago.
  • Naive consumers who either
    • Ignore and throw common sense out of the window when it is needed the most.
    • Assume things that do not exist.

Mix the above 5 reasons and we get a recipe for a disaster. Now guess who will pay for these mistakes? I can assure you neither the bank nor the merchant will pay for anything.

Basically, in my opinion, it is because of pure greed mixed with complete ignorance of consumer protection rights with a topping of naivety from the consumer’s side.

I truly hope things change in the future. I actually see the UAE on a route that ends with enacting laws in this regard to help reduce fraud. I just hope things progress a bit faster.

Building a GPU based Crypto Mining Rig

To build a multiple GPU crypto mining rig, you need to consider the following

  1. Density vs price
  2. The number of GPUs per rig
  3. Power supply
  4. Cooling

It is obvious that the more GPUs, the more the cost associated. The good thing about density, is that you have higher hash rate with less cost compared with building multiple rigs to achieve the same hash rate. The bad thing is that it involves paying for the whole thing at once specially the GPUs.

Currently there are 2 GPU manufactures. AMD and Nvidia. Each has their own line of GPUs however it is important to note that there are 2 kinds of Nvidia GPUs. They are LHR GPUs and the none LHR GPUs

  1. AMD
    • RX580 with 8GB of memory
    • RX5xxx XT
      1. RX 5600 XT
      2. RX 5700 XT
    • RX6xxx XT
      1. RX6600 XT
      2. RX6700 XT
      3. RX6800 XT and RX6900 XT
  2. Nvidia
    • None LHR GPUs
      1. GTX 16xx with 6GB family of cards
      2. RTX 20xx with 6GB family of cards
      3. RTX 3060
      4. RTX 3080
      5. RTX 3090
    • LHR GPUs
      1. RTX 3060
      2. RTX 3060Ti
      3. RTX 3070
      4. RTX3070 Ti
      5. RTX3080 Ti

LHR stands for Lite Hash Rate. It is a technology introduced by NVidia in some of its very successful GPUs to foil crypto miners and get more graphics cards in the hands of gamers. This technology lower the productivity of the GPU significantly and get it produce half of it is full potential on average. There are 2 versions of LHRs currently in the market. V1 of LHR affects only Ethereum mining while V2 potentially affects all mining operations.

Few important points to consider when buying GPUs

  1. Each GPU regardless of manufacture has
    • Its own power consumption profile
    • Expected hash rate depending on the algorithm (what crypto currency to mine)
  2. Please note that Nvidia RTX30xx family of cards, there are LHR and none LHR cards of the same model (for example, RTX 3060 and RTX 3080)

To get an idea about the expected hash rate and power consumption per card, I would encourage you to visit WhatToMine website. Please note that the value you see on the website are estimates to what you might get. Your power draw might be up by 10% more and your hash rate might be lower or higher depending on the manufacture and the infamous silicon lottery

The silicon lottery is basically the quality of the manufacturing process which results in same cards models from the same manufacture scoring different power draw and/or different hash rates.

Now that you know the basics of GPUs, lets talk about building a mining Rig. A mining Rig is just similar to a desktop computer but with multiple GPUs connected to the motherboard. In a normal desktop computer, you have the following key components inside the case

  1. Motherboard
  2. CPU (aka processor)
  3. RAM (aka memory)
  4. Hard disk drive (aka storage)
  5. GPU (aka graphics card)
  6. GPU Risers
  7. Power supply

The good news is that all normal motherboards out there support up to 6 GPUs. To connect more than 6 GPUs, you will need specially motherboards designed for mining. Those mining motherboards can support anything from 6 up to 19 GPUs (under special conditions).

I can’t proceed without mentioning the queen of mining motherboards which is the ASUS B250 MINING EXPERT. That motherboard has 19 PCIe slots to connect up to 19 GPUs. However please note to utilize the full potential of that motherboard, you need to use a specific combination of GPUs from different manufactures (please refer to its manual for details)

For a low density build, you will need

  1. A 6 GPU frame to mount all the different components. You can either buy a ready made frame or build one out of wood.
  2. A regular motherboard (no need to go fancy at this stage since mining motherboard can be expensive)
  3. The cheapest CPU (processor) you can find that would work with your motherboard.
  4. 8GB of RAM
  5. 120GB SSD
  6. 6 GPUs
  7. 6 GPU Risers
  8. Power supply(s).
  9. OS (To make it very simple, I will be using Windows 10)

For a high density build, you will need basically the same components except

  1. Bigger frame to hold the number of GPUs you need
  2. Specialized mining motherboard that can handle the number of GPUs planned
  3. Potentially 2 or more power supplies.
  4. Extra GPUs
    • Please keep in mind that AMD drivers support up to 12 AMD GPUs
    • Please keep in mind that Nvidia drivers support up to 8 Nvidia GPUs connected at the same time
  5. Extra GPU Risers

Regardless of your rig size, please note your power capacity depends on which GPUs are being installed since each GPU model has its own power consumption profile. To illustrate the power point, below are simple examples showcasing the power consumption issue for different GPUs.

If you are building a rig to mine Ethereum (ETH), then a single Nvidia RTX 3080 none LHR edition graphics card – when overclocked and power tuned properly – will consume approx. between 215 to 255 watts of power depending on the manufacture. Another example is the Nvidia RTX 3080Ti graphics cards which will consume anything from 280 watts up to 310 watts depending on the manufacture. AMD RX cards tend to consume less power in general but produces far less hash rate. To illustrate the point of power consumption verses hash rate when mining ETH see below table

GPUApprox. power consumption (Watts)Approx. ETH stable hash rate (Mh/s)
Nvidia RTX 3090320110
Nvidia RTX 3080 (none LHR)25598
AMD RX6800 XT16062
AMD RX6900 XT16062
Approx. power consumption vs approx. ETH mining hash rate

From the table above, it is imperative to calculate the power consumption properly and make sure of the following

  1. To know the approx. power consumption of your GPUs in advance
  2. You plan to have 20% extra power capacity available
  3. Your power socket(s) and wall wiring can handle the power draw otherwise you can blow up your power circuit or worse burn down your house.

The final point that many ignore is cooling. Those GPUs when mining, produce a TON of heat. You need to have a plan to keep them cool otherwise you will end up with lots of issues ranging from stability to potentially bricking your GPUs. To get an estimate about the sort of heat generated by those GPUs, get the sum of their power consumption in Watts and convert it to heat. So for example, a rig that consumes 2000 watts per hour, will be generating heat equivalent to 2000 watts hair dryer running continuously. This sort of heat will in a very short time raise the temperature of room and if left unchecked, will crash the rig or worse damage your hardware.

Financial education

I had no clue about how the financial world works till June 2017. I was a regular person who is content with his salary and thought that savings alone is the safest thing to do. So I had a budget for the family and I was saving monthly a portion of our income. This went on for years. This was the case till one day in June 2017 when my wife told me about the crazy grocery prices in Carrefour. In that evening, she told me the price of 1KG ( 2.2 pounds) of tomatoes jumped to 12 AED (approx. 3.3 US$) and that hit me because a few days earlier the same 1KG price was below 6 AED (1.63 US$). That price difference shock me and made me determined to know and understand what is going with the prices and why – on the long run -prices go up and never come down.

This lead me to come across the following people who helped me a great deal understand the ugly face of today’s financial system. Those people are

  1. Mike Maloney
    1. I honestly urge you to watch his produced episodes titled Hidden Secrets of Money
  2. James Rickards
    1. Watch his interview with London Real published in 2017 on YouTube titled The Road to Ruin
    2. Watch his interview with London Real published in 2019 on YouTube titled PROJECT PROPHESY: Does This Government “Secret” Affect You?
    3. Watch his interview with Grant Williams published in 2019 on YouTube titled Predicting the Currency War and the Case For Gold
    4. if you love reading, then read his books.
  3. George Gammon
    1. Follow him on Twitter
    2. Follow his YouTube channel and watch his 3-step videos to educate your self on how deep the rabbit hole goes.
  4. Brent Johnson
    1. Follow him on Twitter
    2. Watch his The Dollar Milkshake Theory video on YouTube
  5. Peter Schiff
    1. Follow him on Twitter
  6. Harry S. Dent
    1. Follow him on Twitter
    2. His book The Demographic Cliff is a must read. The book is available on Amazon.com
  7. Dr. Chris Martenson on the impact of pandemics on economy
    1. Follow him on Twitter
    2. Follow his YouTube channel

To understand the system farther, both me and my wife decided to venture into online trading. We opened an account with Plus500 in July 2017. We deposited 11500 AED using part of our savings and traded only Gold, Silver and Bitcoin. This went on for several months till I discovered the ugly face of online trading. Our investment grew to nearly 30K AED. Later when I decided not to listen to my inner voice and ventured into the S&P500, we lost around 9K AED. Though over all we were successful, we didn’t like what we discovered in the derivatives markets. It is totally immoral and not ethical. We reached the conclusion that it is worse than gambling. For example, in a Las Vegas casino – by law – the casino must have cash equal in value to the amount of chips on the gambling floor. This isn’t the case in the derivative market. When you buy Gold, Sliver or anything else, you don’t really buy the real thing and rather a claim on that ounce which has been sold to several other people at the same time. This is why I say it is worse than gambling. We decided to cash our 22K AED and leave this trading thing by Sep 2017 and never do it again.

Credit Card Fraud – What is it? And How can you protect yourself?

This article is aimed at the regular Joe and Jane. I will avoid going deep into useless technical details and/or using technical terms. I have posted a very condensed version of this article as a reply to a post on Sep 29th on Dirham Stretcher Facebook group. My aim is to answer the 3 main questions below to help the regular Joe and Jane in their daily life avoid being a victim of credit card fraud.

  1. What is credit fraud?
  2. How credit fraud is committed?
  3. What steps to take to help yourself reduce the risk of being a victim of credit card fraud?

Credit and Debit cards in the developed countries and specially in UAE are becoming an essential tool of our daily lives. The role credit and debit cards play in our daily life has grown at an explosive rate specially after Covid-19. With the lockdowns and work from home environment, ordering things online (food, cloths…. etc.) have become a way of life for so many. With the explosive growth in the number of credit and debit card holders, comes the increased risk of being a victim of credit card fraud. So, what is credit card fraud?

So you may ask, how is this possible? How can someone steal my card? How can someone use my credit/debit card to purchase stuff without my sole authorization?!

To answer these questions, we need to understand that to buy anything online in UAE, all is needed are the following

  • The credit/debit card number
  • Expiry date.
  • CCV

Please note I underlined UAE above. I did this on purpose which will be explained later below when discussing the different vectors of attack.

To answer your questions, please allow me to explain how credit/debit cards are stolen in simple terms without going into the technical part of it. Simply put, there are 3 vectors of attack used by any attacker to get your cards data.

The 1st vector of attack is the owner of the card and the way he/she uses their cards. The 2nd vector of attack is the technology used in today’s cards itself (think contactless cards for example). The 3rd vector of attack is a mixed bag and is partly outside the card’s owner control as it also depends on the merchants themselves. I will briefly explain each vector of attack.

Attack vector 1 – The human factor

As with any technology, the weakest link is the operator also known as the human factor. If you are used to hand over your cards to waiters, gas station personnel…. etc. to process your payments then, it is no longer a matter of if anymore but rather it is a matter of when.

If you have the habit to leave your cards out of your sight, then there is a 50% chance of your card being copied every time it is out of your sight. With that kind of probability, you can’t be lucky 100% of the time.

The only defense against this vector is to NEVER leave your cards out of your sight and NEVER hand your cards over to anyone to process your payment.

The same approach applies to how the card owners handle calls and/or SMS pretending to be related to their cards. For example, NEVER answer any security questions to any caller claiming to call from any bank you are dealing with even if the caller references an issue that you personally reported. What you must do is tell the caller “Please update the ticket and I will call the authorized bank phone number and check your update.”

NEVER click on URLs embedded in SMS messages and NEVER answer security questions from incoming calls regardless of how dire the situation sounds.

Attack vector 2 – The technology factor

The technology used in today’s cards introduces more risks than many really understand or anticipate. With NFC and contactless cards for example, all you need is a card reader that sweeps close enough to your card to read all its data.

The only defenses against this vector are

  1. Get a RFID/NFC protected wallets that would block your card from being read by any RFID/NFC type reader while it is in your pocket.
  2. Use technologies like Apple Pay and Samsung Pay.

Attack vector 3 – The dark forest

This is one of trickiest vectors of attack. When we shop online today, we might tend to assume certain things. For example, if the website looks professional then we might assume that it is OK. The truth is far from that. It all depends on the laws and regulations of the country where such company is based and that assuming it is an authentic company to begin with.

The reason behind this is simple. Countries where ecommerce is tightly regulated, have tons of laws and regulations in place forcing merchants and banks to, for example,

  1. Encrypt their databases
  2. Store only the last 4 digits of the card used in the transaction
  3. Encourage banks and payment processors to match card related information like owner name, home address, and phone number with the ones entered by the buyer. (this step alone will reduce fraud cases drastically)

When we come to UAE, for example, I personally don’t know of any laws like the ones stated above. Please consider that doing all these things need a significant amount of money and trained trustworthy personnel to deploy and operated these solutions.

If anyone know of a specific law in the tech sector to this effect, please reference it and I will review it and include it to this article.

Between the extra spending required by the businesses, the race to make a quick buck and the lack of laws, the customer and sometimes the merchant become the ultimate victims. As a result, any hack these companies suffer makes it very easy for the hackers to get the customers data.

Please note I am assuming here that we are dealing with authentic companies that are not doing their part in protecting their customer’s data.

There is no 100% fool proof defense against this attack but rather you need to do few things to protect yourself and reduce the risk of being a victim of fraud

  1. Do your due diligence and research the website in question before you make any purchases.
  2. NEVER save your card details on any website specially those belonging to companies based outside USA and Europe.
  3. NEVER use your debit card to pay for anything (I will explain why below).

Finally, some simple additional tips to reduce the risk of failing victim to fraud. These tips will be divided into 2 groups. Card related tips and technology related tips.

Card related tips:

  • Lookout for suspicious links whether it is in an email or SMS. Malware and spyware can easily get into your devices if you aren’t careful enough. Don’t open e-mails, links or attachments unless you know and trust the sender to stay safe. As to SMS, do not open any links embedded in an SMS.
  • Don’t be in a hurry. The more a caller try to push you and make it sounds like the sky is falling, the more you should be very suspicious and should end the call. Fraudsters will try to convince their targets by creating a false sense of urgency. All banks advertise that they do not call their customers asking for their information so you should be very suspicious if you receive a call, regardless of how dire it sounds, asking for your information. If you’re suspicious, end the call and then call your bank using the authorized number found on the back of your credit/debit card and report it.
  • Keep an eye on your SMS transaction notifications and call your bank immediately if you see something suspicious.
  • Limit the use of your debit card to ATM withdrawals ONLY. Do not use your debit card to buy anything offline (at a physical store) or online. I will explain why below
    • The reasons behind this lay in the difference between debit and credit cards. There are 2 main differences between debit cards and credit cards in fraud cases. The 1st is related to the claim process and the time taken to get your money back due to the different nature of the cards. The 2nd difference is related to the spending limits. Due to the fact debit cards are linked directly to your bank account(s), fraud claims take much longer to get your money back. From the stories I have heard, it is on average 4 to 6 months. This isn’t the case with credit cards assuming you report it right away. With credit cards, you get your funds back usually within a couple of weeks or less. Now regarding limits, with credit cards, you have control on the credit limit (aka spending limit). You can request your bank to lower your credit limit thus reducing any potential losses from fraud. This isn’t the case with debit cards as their limit is bound with how much you have in your bank account(s).
  • Lower the limit of your credit card(s) to a reasonable and manageable level. Having a limit that is 3 to 5 times your monthly salary or more for example is not a good idea at all. My personal advice is lower your limit to be equal or less than your monthly salary specially if you carry multiple credit cards.

Technology related tips:

  • Try to use Apple Pay or Samsun Pay as they will offer you some protection from vector 2 attacks as long as you do not walk around with your cards in your pocket in a non anti NFC/RFID wallet.
  • Use authentic OS on your PC/laptop. Cracked OS versions most of the time come with hidden Malware and spyware which can harvest all the information you type (they are called key loggers as they record the sites you visit and record your keyboard strokes). These Malware and spyware can be used to help a hacker steal your email, Facebook, bank account… ect.
  • Install Norton Safe Web browser extension to your browser. It is available for Google Chrome and FireFox. There is a similar product by McAfee called McAfee WebAdvisor. These products will help you identify safe websites when you google anything as they will be marked with green mark.
  • Use a properly updated antivirus software on your Phone and PC/laptop. If you favor professional paid versions, then I would recommend you check Symantec Norton 360 which I have been using for years and isn’t that expensive for a multiple platform license. If you favor the basic free version, then I would recommend AVG free antivirus.
