What Africans should know about cyber security

As simple as avoiding opening suspicious emails, activating two-factor authentication, and more, are cyber securities.


Many people may believe that cybersecurity might need years of experience or a highly technical background. Still, in reality, cybersecurity isn't challenging although there may be difficult concepts, like cryptography, or areas that require more technical knowledge.


Individuals, organizations, and companies can apply simple levels of cybersecurity.

Whether you are an individual, small business owner, or large multinational, you rely on computer systems daily. Cyber security should be practiced to protect against phishing schemes, identity theft, data breaches, and financial losses. In this article, we will take a look at some simple precautions for cybersecurity.


These precautions can save your email and social media accounts from being hacked.

Cyberattacks put your money, data, and IT equipment at risk. If a hacker gains access to your network, they can inflict significant damage with what they find.


      It's important to protect your business from cyberattacks, but with the cyber landscape evolving all the time, it can be daunting to know where to start. Here’s a guide to help small businesses navigate the world of cyber threats.



1:Secure Your wifi-networks


Businesses can protect their Wi-Fi network from breaches by hackers by changing the name of their wireless access point or router, also known as the Service Set Identifier (SSID). They can use a complex Pre-shared Key (PSK) passphrase for additional security.


2:Guard against physical theft


While businesses need to be mindful of hackers trying to breach your network, they mustn't forget that  hardware can be stolen too. Unauthorized individuals should be prevented from gaining access to business devices such as laptops, PCs, scanners, and so on. This may include physically securing the device or adding a physical tracker to recover the device in case of loss or theft. Ensure all employees understand the importance of any data that might be stored on their cell phones or laptops when out and about.


3: Ensure third parties who deal with your Business are also secured.


Be wary of other businesses such as partners or suppliers who may be granted access to your systems. Make sure they are following similar practices to you. Don’t be afraid to check before you grant access to anybody.


4: Training Employees.


Invest in cyber security trainings for the employees,for instance they can be educated with the importance of strong password and how to spot phishing emails.And also educate  them on the different types of cyber attacks and how to avoid and navigate them.


5: Deploy Anti-virus software.


Choose softwares that can protect business devices from viruses.keep antivirus updated to avoid latest cyber threats.

Businesses can also employ the service of cyber security experts to help the business remain secured.


6:Back up business files regularly.


When you cyber attacks occur,files and data can be compromised or lost/deleted.But if the business has been current in backing up it's files and data it might avoid the end of the business due to loss of important files or data .

Also choose a program that gives you the ability to schedule or automate the backup progress.


7:Limit access to sensitive data.


Restrict the number  of people in a business  environment with access to critical data to a minimum.so as to avoid the impact of bad faith actors in the business.set up strategies that will help assign important task to individuals or groups that are identifiable and can be held responsible and accountable.


    Cyber threats aren't just a problem for big corporations and governments – small businesses can be targets too. In fact, there is evidence that small businesses are more vulnerable to cyberattacks, not least because they sometimes lack the resources to protect themselves effectively.

Cryptocurrency adoption has continued to ride and thrive like a moving train, despite the hurdles that have stood in front of the industry. On a continent that was once believed to be an ancient relic of a primitive time, cryptocurrency has turned out to be of great interest to young Africans. In Nigeria, for instance, there are different perceptions of the industry. Some believe anything that has cryptocurrency in it is a scam, while others believe it is simply a get-rich-quick scheme. Thanks to various organizations and companies that have dedicated their time to organizing events to cure myopia among the African populace, we are getting a better idea of what the industry really is about. Before we get into the topic of the day, let's know what cryptocurrency wallets are.


What Are Cryptocurrency Wallets?


Cryptocurrency wallets are digital wallets used to store digital assets like Bitcoin and Ethereum securely. According to the Coinbase website, "crypto wallets keep your private keys—the passwords that give you access to your cryptocurrencies—safe and accessible, allowing you to send and receive cryptocurrencies like Bitcoin and Ethereum. They come in many forms, from hardware wallets like Ledger (which looks like a USB stick) to mobile apps like Coinbase Wallet, which makes using crypto as easy as shopping with a credit card online."


 Cryptocurrency wallets are not like traditional wallets. Unlike a physical wallet that can be stolen or lost, a crypto wallet is a digital asset that can be easily accessed by hackers if not secured properly. They are computer or mobile software programs that employ an internet connection to connect to the blockchain network of the cryptocurrency you're making use of. Cryptocurrencies aren't just kept anywhere. They are pieces of data saved in an organized database or ledger. These pieces of information are dispersed throughout the database; nevertheless, the wallet locates all the pieces connected to your public address and adds up the total for you via the app's UI.


Using these applications, sending and receiving cryptocurrency is incredibly simple. Several options are available for sending and receiving cryptocurrency from your wallet. The standard procedure is to enter the wallet address of the receiver, select an amount to transfer, sign the transaction using your private key, add funds to cover the transaction fee, and send it.


There are two types of wallets, custodial wallets and non-custodial wallets. Custodial wallets are hosted by a third party, which might be a company that offers high-level data security technologies used by companies to protect and safeguard their data. Some crypto exchanges offer these services to their customers. Non-custodial wallets are wallets where you are responsible for securing your keys. This is the type of wallet that most cryptocurrency wallets on devices use. There are also two categories of wallets: hot and cold. A hot wallet is one that has an internet connection, while a cold wallet does not.


Now that we have basic knowledge of what crypto wallets are, let's explore some of the best practices to keep your wallet safe.
 
1. Choose a Reputable Wallet Provider: The first step in securing your cryptocurrency wallet is to choose a reputable wallet provider. Do thorough research before selecting one, and find out which providers have a strong history of safe operations. Some popular wallet providers to consider include Trust Wallet, Ledger, Trezor, and MyEtherWallet, while you could also consider saving your funds with crypto exchanges like CoinW and Binance.
 
2. Use Two-Factor Authentication: Two-factor authentication adds an extra layer of security to your wallet. It requires you to enter a code generated by an app or sent to your phone before accessing your wallet. This can help protect your wallet against hacking attempts.
 
3. Keep Your Private Keys Safe: Your private key is like the password to your cryptocurrency wallet. If someone gets hold of it, they can easily access your funds. Never share or store your private key online. Instead, store it on an offline device like a hardware wallet or a paper wallet.
 
4. Use a Strong Password: A strong password should be complex and contain a mix of uppercase and lowercase letters, numbers, and symbols. Avoid using easy-to-guess passwords like your name or birthdate. Change your password regularly and do not use it on any other online accounts.
 
5. Keep Your Wallet Software Up-To-Date: Keeping your wallet software up-to-date is important because it ensures that any security loopholes are fixed. Developers often release updates to address any vulnerabilities identified in the previous version.
 
6. Backup Your Wallet Regularly: If you lose access to your wallet or forget your password, a backup can save you. It is important to store backups of your wallet on other devices in case your primary device is damaged or lost.
 
7. Be Cautious of Phishing Scams: Phishing scams are common in the cryptocurrency space. Fraudsters often send fake emails and messages asking for your private keys or other sensitive information. Always verify the authenticity of any email or message before responding.
 
In conclusion, securing your cryptocurrency wallet requires a bit of effort, but it is worth it to protect your assets. By following the best practices outlined above, you can help keep your crypto wallet safe from hackers and other types of security breaches.

Tunisia, a small country in North Africa, may not be the first place that comes to mind when you think of tech startups. But over the past few years, the country has experienced a boom in entrepreneurship and innovation, with a growing number of startups disrupting traditional industries and solving unique local challenges.


One of the most exciting areas of growth in Tunisia's tech scene is in the fintech sector. In a country where nearly half of the population is unbanked, startups like Paymee and Expensya are helping to bring financial services to underserved communities. Paymee, for example, allows users to make payments and transfer money using their mobile phones, while Expensya helps businesses manage their expenses and streamline their accounting processes.


Another area of innovation in Tunisia is in the field of education technology. With the COVID-19 pandemic forcing schools to close and shift to online learning, startups like GoMyCode and Edumetric have stepped up to provide digital learning solutions for students and teachers. GoMyCode offers coding bootcamps and tech courses online, while Edumetric provides a platform for teachers to create and share educational content.

Tunisia's tech startups are also making waves in the travel and hospitality industry. With tourism being a major source of income for the country, startups like Trip4Care and Wibees are helping to attract more visitors and enhance the travel experience. Trip4Care offers medical tourism services, while Wibees is a platform for booking unique and authentic experiences with local hosts.


Of course, Tunisia's tech scene still faces its share of challenges, including a lack of funding and a shortage of skilled talent. But with the government and private sector investing more in innovation and entrepreneurship, the future looks bright for Tunisia's startups.

In conclusion, Tunisia may be small in size, but it's big on ideas and innovation. From fintech to edtech to traveltech, the country's startups are pushing boundaries and driving progress. Who knows – the next big tech unicorn could be born in Tunisia.

South Africa is known for its beautiful landscapes, diverse wildlife, and world-class wine. However, few people know that technology is playing a vital role in the country's wine industry. In recent years, South African winemakers have been using a range of cutting-edge technologies to produce better-quality wine, reduce waste, and improve their yields.

One of the main areas where technology is making a difference is in vineyard management. By using sensors to monitor the soil, temperature, and moisture content, winemakers can make better-informed decisions about when to irrigate, fertilize, and harvest their grapes. Drones are also being used to collect data on vine health and monitor the spread of diseases and pests.

In addition, winemakers are using technology to improve the winemaking process itself. For example, some are using digital tools to track the fermentation process and ensure that the wine is of a consistent quality. Others are using 3D printing to create customized wine barrels that are more efficient at storing and aging the wine.


These innovative approaches are not just improving the quality of South African wine. They are also helping winemakers reduce waste and increase efficiency. By using technology to optimize their production processes, winemakers can reduce their energy consumption and water usage, which is not only good for the environment but also for their bottom line.

Overall, technology is transforming the South African wine industry, enabling winemakers to produce better-quality wine more sustainably. As the industry continues to innovate and adapt, consumers can expect to see even more exciting developments in the future.

👉🏻select privacy and safty

👉🏻select location 

👉🏻select Disabled 


vula! you are all done. This procedure may varry from app to app, but it is really easy to navigate .

Go ahead and "turn off your location"

As the popularity of Cryptocurrency increases - a new form of malware (malicious soft) has emerged called Cryptojacking.


What is Cryptocurrency? : They are digital currency (e.g. Bitcoin, Ethereum) that can be used in exchange for goods, services, and even real money. Cryptocurrency can be purchased or earned through “mining”.  


The term Mining, involves using a computer to solve complex, encrypted math equations in return for a piece of cryptocurrency.


What is Cryptojacking: Cryptojacking occurs when cybercriminals use a victim’s computer, tablet, or mobile device to mine for cryptocurrencies without their knowledge. Unlike most other types of malware, cryptojacking scripts do not normally cause damage to victims’ data.  However, Cryptojacking does slow down a victim’s computer and internet connection and can cause battery drain.



How Does Cryptojacking occurs?


  • Malicious Applications: Hackers trick victims into loading crypto-mining code onto their computers, through phishing-like tactics. Victims receive a legitimate-looking email that encourages them to click on a link that installs crypto mining software that runs in the background.
  • Malicious Websites (Drive-by cryptojacking): Victims visit a site that runs a malicious script or is hosting a malicious advertisement. The script can do one of two things:
    • If the website is open, the user’s computer can be used to actively “mine” for cryptocurrency. This "Drive-by" attack can compromise any device with a web browser.
    • The website can use a script to install a malicious application without your knowledge
  • Github: GitHub is a web-based platform for collaborative software development (software can use code shared on GitHub).  Some Hackers will take code that is shared and hide cryptojacking malware within a fork of the project.

How Can I  Prevent Cryptojacking Malware

  • Here are some helpful preventive measures 
    • Keep all your software and devices up-to-date with the latest patches and fixes. Many attacks exploit known vulnerabilities in existing software.
    • Only install software from trusted sources.
    • Avoid suspicious websites (e.g. torrentingshortened URLs) that can host these malicious scripts.

How Can I  Detect and Recover from Cryptojacking

  • Symptoms of cryptojacking can include unexpected high processor usage (indicated by sluggish or slow response times) overheating of your device, and poor battery performance
  • If you think you are victim of Cryptojacking close all of your browser windows to exit your browser, remove any browser extensions, and run an antivirus scan. If an NJIT owned PC, open the McAfee Endpoint Security application and select “Scan System”.   Otherwise, scan your computer using your installed virus protection.

Remember to always stay ALERT ‼️

Here are 8 possible ways you can be inviting a cyberattack 


1. Invisible systemic risk

Businesses, Organizations and Individuals make decisions every day that negatively impact their security readiness: for example, refusing to shut down a server for proper patching or choosing to keep working on old hardware and software to save budget. These unreported decisions lead to a false sense of security and increase the likelihood and severity of an incident.


2. Cultural disconnect

Non- IT folks still see Cybersecurity as something that is “just there,” like air or water. This means it isn’t considered a part of business decisions


3. Throwing money at the problem

You can’t buy your way out — no matter what you spend, you won’t be perfectly protected against cyberattacks. By trying to stop every risky activity, you will likely damage your organization’s ability to function.


4. Security as “defender”

If security officers are treated as (and act as) defenders of the organization, it creates a culture of no. For example, they might block the release of a critical application due to security concerns without considering the business outcomes the application supports.


5. Broken accountability

Accountability should mean that a decision to accept risk is defensible to key stakeholders. If accountability means that someone will get fired if something goes wrong, no one will engage.


6. Poorly formed risk appetite statements

Organizations create generic high-level statements about their risk appetite that don’t support good decision making. Avoid promising to only engage in low-risk activities, as this can create invisible systemic risk


7. Unrealistic social expectations

When a headline-grabbing security incident happens, society just wants heads to roll. While this isn’t fair, it’s the result of decades of treating security as a black box. No one understands how it really works and as a result, when an incident does occur, the assumption is that someone must have made a mistake.

However, society is not going to change until organizations and IT departments start treating and talking about security differently.


8. Lack of transparency

Some boards and senior executives simply do not want to hear or acknowledge that security isn’t perfect. Board presentations are filled with good news about the progress that has been made in security, with little or no discussion about gaps and opportunities for improvement
