Early technology adopters are more likely to gain better business results, including higher revenue growth and market position. With businesses facing complex problems every day, it is no doubt that they are always watching out for the next big tech that offers a better solution.

Although still in its infancy stages, quantum computing is a technology whose commercial use will disrupt the business environment.

What is Quantum Computing?

Quantum computing is a technology that focuses on manipulating and controlling different laws of physics. This non-classical technology uses quantum mechanical concepts like superposition and quantum entanglement.

The idea of quantum computing is not new and has come a long way. The first algorithm of large integer factorization for quantum computing was introduced in 1994. This algorithm intended to reduce the time it would take classical computers to find the prime factors of large numbers. It’s worth noting that the majority of the current infrastructure for encryption and information security is built on prime factorization.

Since the first algorithm was developed, more technological advances have been reported, and the field is continuously receiving funding. According to the McKinsey & Company Quantum Technology Monitor, funding from private and public sectors for this new technology is skyrocketing worldwide.

How it Works

Unlike classical computing, whose information is encoded by bits, in quantum computing a qubit is the basic unit of quantum information. Qubit allows all combinations of information to exist simultaneously so that quantum computers can solve problems exponentially faster and with less energy consumption than classical computers.

In 2019, Google, in partnership with NASA, achieved quantum supremacy by demonstrating that quantum computers can compute in seconds what would take advanced supercomputers thousands of years.

Advanced development in this technology has also seen the introduction of quantum-computing cloud infrastructure through Quantum as a Service (QaaS). QaaS provides access to quantum computing platforms over the internet to customers. Major technology companies, such as Amazon, Alibaba, IBM, Google, and Microsoft, have already launched commercial cloud services for quantum computing.

With the continued increase in the quantum computing ecosystem and emerging business use cases, business leaders must stay aware and prepare to adopt the new technology.

Business Use Cases for Quantum Computing

1. Quick Data Analytics

Today more than ever, businesses are faced with big data and a large quantity of information requiring analysis and storage. Since classical computers are built to solve one task at a time, it takes longer to solve these complex problems.

However, quantum technology has the potential to turn complex computations into simple calculations that are solved in less time.

2. Optimize Investment Strategies

Optimization is all about finding the most ideal solution in a situation. When many options are available, it takes a classical computer a long time to find a solution. Therefore, classical computers use shortcuts, and the final solution is partly optimal. But, with quantum computing, there will be better optimization.

3. Better Forecast and Prediction

Businesses rely on forecasts and predictions generated after analyzing complex and large data sets. Quantum computing is built to process huge amounts of data quickly and more accurately. As a result, better forecasts and predictions will enable better decision-making.

4. Solve Problems With Financial Services

There are various computationally intensive jobs in finance that could be facilitated by quantum computing, such as credit-risk management, financial crime reduction, and trading strategy optimization. These tasks will greatly benefit from quantum algorithms that increase the speed of financial calculations.

5. Improve Data Security

Quantum computers are built to break encryptions that ordinary computers cannot. This might become a problem if hackers were to acquire encrypted data and store it until large-scale quantum computers are operational. To handle this problem, postquantum cryptography, a type of cyber security that can be used by conventional computers, is currently being developed. Therefore, a switch to quantum-resistant cryptography will prevent the possibility of data being exposed. At the same time, it will ensure better protection of digital assets.

Final Thoughts

Quantum computers will not replace classical computers; however, the two will form a hybrid solution whereby each task will be assigned to the most suitable machine – either quantum or classical.

Achieving the aforementioned benefits will require businesses to have teams of experts who are knowledgeable about the implications of quantum computing and who can recognize the company’s potential future needs, opportunities, and vulnerabilities.

With signs of commercial quantum computing becoming a reality, it’s not too early for business leaders to consider how it will encourage digital investment, reshape industries and ignite innovation. Therefore, having a thorough understanding of quantum applications is essential for positioning a business to gain a competitive edge.

Deepfake technology utilizes machine learning and artificial intelligence (AI) to manipulate or create synthetic audio, video and images that appear authentic. Deepfakes are commonly featured in entertainment and politics to spread false information and propaganda. For instance, deepfake has been used to show a celebrity or leader saying something that they didn’t, and this creates fake news.

Unfortunately, in deepfakes, cybercriminals have found a new tool for cyberattacks. Cybercriminals are now using deepfakes to pose a variety of enterprise risks.

How Cybercriminals Are Using Deepfakes

Deepfake technology is now used to create scams, hoaxes and false claims that undermine and destabilize organizations. For instance, a manipulated video might show a senior executive associated with fake news, such as admitting to a financial crime or spreading misinformation about a company’s products. Such corporate sabotage costs a lot of time and money to disprove and can impact a business’s reputation.

Another way businesses can be negatively impacted is through social engineering attacks such as phishing, which relies on impersonation to compromise an email. Similarly, social engineering using deepfakes can feature voice or video impersonations. A good example of such an impersonation was reported in The Wall Street Journal, in which fraudsters used AI to mimic a CEO’s voice. This incident happened in March 2019, when criminals impersonated a chief executive’s voice to direct a payment of $243,000.

Cybercriminals are able to execute social engineering attacks by accessing readily available information online. They can research a business, employees and executives. The criminal will even use an actual event picked from social media – for instance, a financial director who is just returned to work from a holiday – to sound more legitimate.

This emerging security threat is also made possible by the development of video editing software that can swap faces and alter facial expressions. Such developments have enabled deepfakes to fool biometric checks (like facial recognition) to verify user identities.

The deepfake cybersecurity threat has become such a concern that the Federal Bureau of Investigation (FBI) has issued a Private Industry Notification (PIN) cautioning companies of the possible use of fake content in a newly defined cyberattack vector referred to as Business Identity Compromise (BIC).

How to be Prepared and Protect Against Deepfakes

Deepfake videos and images can be recognized by checking for unnatural body shape, lack of blinking in videos, unnatural facial expressions, abnormal skin color, bad lip-syncing, odd lighting, awkward head and body positioning, etc. However, cybercriminals keep evolving and creating more convincing deepfakes.

Other measures introduced to combat deepfakes include creating solutions that detect deepfakes. There also was an introduction of deepfake legislation in the National Defense Authorization Act (NDAA) in December 2019.

Unfortunately, this has not been enough, and enterprises have the task of helping reduce the impact of these attacks. The following measures can help:

1. Use anti-fake technologies
   Businesses should explore automated technologies that help identify deepfake attacks. They should also consider watermarking images and videos.
2. Enforce robust security protocols
   Implement security protocols to help avoid deepfakes, such as automatic checks for any procedure involving payments. For instance, putting systems that allow verification through other mediums.
3. Develop new security standards
   As security threats keep evolving, so should security standards within a company. For instance, introduce new security standards involving phone and video calls.
4. Training and awareness
   Enterprises should enforce regular training and raise awareness among employees, management, and shareholders on the dangers of deepfakes to businesses. When all involved parties are trained to identify deepfake social engineering efforts, this will help reduce the chances of falling victim.
5. Keep user data private
   Deepfake attackers use the information found in public domains such as social media. Although not a failsafe procedure, company profiles can be made private. Users also should avoid adding or connecting with strangers they don’t know and posting too much personal information online.
6. Disinformation response policy
   Some deepfake incidents are out of control for an enterprise, such as fake videos purporting to be from top management. However, establishing a disinformation response plan will help in cases of a reputation crisis. This should include monitoring and curating all multimedia output – which will help present original content to the public as authentic content.

Conclusion

Deepfake is an emerging cybersecurity concern that requires enterprises to be aware of its potential threats and stay prepared. Although it might be possible to identify a poorly generated deepfake with the naked eye, the technology continues to advance. In response, countermeasures must keep pace.

Web browsers such as Google Chrome, Firefox, Safari and Edge, among others, play an essential role in enabling access to websites on the internet. Most browsers allow users to install extensions, also referred to as add-ons or plug-ins. These extensions are applications or small software modules that add functionality and other useful features to a browser.

By means of the extensions, users can carry out various tasks such as password management, cookie management, ad blocking, interface modification, productivity tracking, grammar and spell-checking, etc.

However, although the extensions offer different useful functionalities, cybercriminals have taken advantage of them, creating a security risk to users and their data.

The Need to Beware of Browser Extensions

Browsers enable websites to collect information such as viewing history, adding cookies, etc. Also, when installing the extensions, some require to be allowed various permissions, like the ability to read or change data. For instance, according to a recent study by Talon, a digital security company, most Chrome Web Store extensions (62.43 percent of extensions) require dangerous permissions, including permission to read or change user data and activity. This means that an extension can see the sites visited, keystrokes, login credentials and private data, such as payment card details.

Since this information is readily available on a user’s web browser, cybercriminals can use a malicious extension to collect the data for their gain. At the same time, the data collected is sold without user consent or knowledge and used by third-party data brokers to send users tailor-made ads.

Although not all browser extensions are a security risk, some might be built to impersonate legitimate extensions, especially those from third-party resources. In other cases, legitimate extensions have been compromised or bought by a developer who uses them for malicious purposes.

Some browser add-ons are built to download malware onto your device, redirect search traffic to malicious websites or download ad ware and Trojan horse viruses.

The extensions can automatically update without requiring any action from a user. This means that if a legitimate extension is compromised, it can be used to install malware without user knowledge. Even secure extensions are prone to attacks or can be compromised, enabling attackers to gain access to data stored by browsers.

Additionally, malicious extensions can be built to bypass fraud detection by official Web stores. For instance, in 2020, Google removed over 500 extensions from its web store that violated policies, with some already having infected users and stolen their data. This followed the discovery of some malicious extensions that users had already downloaded.

A recent report released by Kaspersky, a cybersecurity firm, shows just how dangerous malicious add-ons are. After the firm analyzed data from January 2020 to June 2022, it discovered that over this time frame, 4.3 million users were attacked by adware hiding in browser extensions. This put adware as the highest representative of browser extension risks, with malware coming second. The report also indicates that Kaspersky products prevented more than 6 million users from downloading adware, malware or riskware disguised as browser extensions.

Such figures from just one cybersecurity firm are worrying, considering the study focused only on users that use their security solutions. This creates a need for users to be more vigilant when using browser extensions.

How to Make Sure Browser Extensions Are Safe

There are various ways to help reduce the risks posed by browser extensions:

1. Ensure the extension is from an official web store. Since these extensions can also be compromised, it is best to find out more information about the developer.
2. Check reviews as they help to know what other users think of the extension and if there have been any complaints. However, users should be cautious of identical comments or too many 5-star reviews, as these could be fake.
3. Check whether the extension is updated regularly. An extension last updated many years ago might not be reliable.
4. Review extension permissions for each extension.
5. Check that you are not installing clones of the original extension. For instance, if you search for an extension, you can find other similar ones that look legit.
6. Uninstall browser extensions that you don’t recognize or those you no longer need.
7. Use browsers that have the features you want.
8. Install reliable antivirus software that will help spot malicious activities or applications.

Conclusion

Browser extensions play an important role in the user browsing experience. Although not all extensions are dangerous, users must conduct due diligence to ensure they install legitimate extensions.
