Phishing, Cybersecurity and Your Small Business

Phishing can have a significant and often devastating impact on small businesses. Unlike larger organizations, small businesses typically have fewer resources to dedicate to cybersecurity, making them an attractive target for cybercriminals.

Small businesses can be impacted by phishing and other types of attacks in ways that might not have been considered before. Here are some of the more common ways that phishing attacks can impact the business:

Financial Loss
Phishing attacks often result in direct financial losses due to funds being stolen, fraudulent payments being made, and ransoms being paid. Cybercriminals often use phishing emails to trick employees into transferring money to fraudulent bank accounts, and attackers may impersonate legitimate vendors or clients to request fake payments. Worse, phishing emails can be used to deliver ransomware, locking up or encrypting critical systems or data until a ransom is paid.

For small businesses, even a single financial loss can be catastrophic.

Data Breaches
Phishing can lead to the compromise of sensitive business information or customer data, such as customer personal information or payment details, employee credentials or other private information of the employee, or business trade secrets and other proprietary business data. Data breaches can easily result in legal liabilities, fines, and damage to the business reputation.

Reputational Damage
When a phishing attack exposes sensitive customer information or disrupts services, it erodes customer trust. This can lead to clients taking their business elsewhere and makes attracting new customers harder. It could also impact vendor relationships, causing partners to view the business as a weak link in the supply chain.

Operational Disruption
Cyber-attacks, including phishing attacks, can disrupt business operations and cause numerous problems. Ransomware or malware delivered through phishing emails can render IT systems unusable, causing loss of productivity. If employees lose access to critical tools, files, or data, there will be delays in work and projects. Businesses also must divert time and resources to recover from attacks, taking away from regular business operations and revenue-generating activities.

Why Small Businesses Are Often Targeted
Small businesses are rich targets for cyber-attacks, especially phishing, because they often have weaker defenses compared to larger enterprises. Often made up of a few trusted employees, small businesses are attacked in ways that exploit trust and personal familiarity. Due to many small businesses having weaker cyber-defenses, attackers can find high payoffs in financial rewards or valuable data with a single successful phishing attack.

Noobeh Helps Businesses Protect Themselves
Every business should teach their employees how to recognize and report phishing emails, and MFA (multi-factor authentication) should protect all accounts, but human beings can only do so much, so it makes sense to implement tools that can put additional intelligence behind your services and defend your systems to help keep the problem from ever getting to your users.

Our team at Noobeh recommends and provisions Microsoft Defender for Office 365 to block phishing emails and messages with malicious links and content. Advanced email security helps reduce inbox spam and blocks messages from spoofed senders, which helps prevent users from interacting with bad emails and potentially exposing protected information.

Email protection is only part of the needed coverage. Noobeh also recommends having strong endpoint protection solutions to detect and prevent phishing-related malware and other attacks. Microsoft Defender for Endpoints does this, working seamlessly with our remote monitoring and management and your other Microsoft services to provide a higher level of protection for the business.

By understanding the risks and taking proactive measures, small businesses can minimize the impact of phishing attacks and protect their operations, reputation, and customers.

Cybersecurity and Small Business

Small businesses face many challenges as they grow and expand, and chief among them is the growing threat of cyber-attack. As the company grows, its value to cybercriminals grows, too. Implementing comprehensive cybersecurity measures is essential to maintaining customer trust and safeguarding important business data against these threats.

There is a belief among small business owners that their operations are too small or insignificant to be attractive targets for cybercriminals. Cybercriminals, on the other hand, more often view small businesses as easy targets. Why is this? Largely because the bad guys know that the smaller companies aren’t spending on cybersecurity services and tools and aren’t always keeping their workers informed about ways they can participate in keeping things safe.

To help protect the business from cybersecurity threats, it is crucial to invest in some key security measures. Longer and more complex passwords, regular software patching and updating, and periodic training for employees on how to identify phishing attempts and what to do with suspicious emails is a good start. Cybersecurity efforts should scale with the business, and this requires strategic planning that is aligned with the goals and objectives of the business.

The best cybersecurity approaches are built on a secure foundation, and this is what helps to support business growth and expansion. For every business, there are four cornerstones of a solid cybersecurity foundation.

  • Identifying potential cyber threats and understanding the business risk they represent.
  • Enforcing strong password protection and role-based access controls.
  • Following best practices in cybersecurity.
  • Managing documentation and vital business information securely.

Cybercriminals know that smaller businesses generally have limited cybersecurity resources, making small businesses prime targets for phishing and malware. What is the potential impact of falling for a phishing email, or what happens if there is a ransomware attack? Each type of threat carries different levels of risk, and growing businesses should be aware of the potential financial, legal and reputational impacts when evaluating their approach.

Businesses can help their users become part of the cybersecurity plan by regularly training them on phishing methods and ways to avoid ransomware or malware. When users know more about emerging threats and how to recognize and report suspicious things, they become valuable assets in the improvement of cybersecurity of the business.

The first line of defense in cybersecurity is the username/password challenge. Many systems today use an email address as the username or user ID, which means it really isn’t much of a challenge to guess. This leaves it to the password to keep the account secure, so a strong and unique password is necessary.

Making another challenge to the authentication adds another layer of protection to the account. Referred to as 2FA or MFA (two-factor authentication or multi-factor authentication), users may be required to respond to an in-app message, provide a code received via SMS or other, or provide a code from an authenticating application to satisfy the login requirements. This additional challenge to the user identity makes it harder for cybercriminals to gain unauthorized access.

Ensuring the protection of sensitive business information requires controlling what users have access to once they are in the system. If someone were to gain unauthorized access, having appropriate role-based access controls in place would limit their ability to get sensitive data. This is often another area of vulnerability for smaller businesses that don’t implement strict document controls or structures, opting instead for an open self-service model that leaves data available to whomever can get logged in.

With businesses changing frequently, it is important to not just create a framework to limit user access, but to keep user and role-based access reviewed and updated regularly. Software and systems also need to be updated regularly. Known software vulnerabilities should be patched and security updates installed on devices, and policies enforcing updates and antivirus/malware detection should be implemented.

We understand that businesses must enhance their cybersecurity strategies to combat the growing number and type of cyber threats, and it can be challenging just figuring out what to do first. Working with a variety of technologies and specialists, we can help secure your digital environment and keep you better-protected from the bad guys.

Cybersecurity and Retail Should Always Go Together

Retail cybersecurity is a critical concern for every business in the retail industry, which is why cybersecurity and retail should always go together. Retailers are prime targets for cyberattacks due to the valuable customer data they collect, which usually includes personally identifiable information (PII) and credit card numbers. Retailers can handle large volumes of customer data, which becomes an attractive target for cybercriminals seeking to profit from selling it on the dark web.

Recent statistics from various sources suggest that more than 24% of cyberattacks specifically target retailers, making it one of the most heavily targeted industries. Roughly one third of retailers cite cybersecurity concerns as their primary obstacle in transitioning to e-commerce, with cost and technology barriers coming close behind.

For the bad guys, however, it is all about the money. Almost all retail cyberattacks are driven by financial motives. When consumer data is compromised, most of the information exposed consists of payment information and personally identifiable data which can fetch a good price on the dark web.

Retail cybersecurity threats occur because the environment tends to have a lot of elements. The hybrid nature of many retail businesses introduces additional risk, where brick-and-mortar stores are combined with e-commerce platforms and services.

NFC (Near Field Communications) vulnerabilities exist in some payment systems, and many Point of Sale (POS) systems still do not use point-to-point encryption for their communications. Even if communication streams are encrypted, it makes little difference if the software has known vulnerabilities or if insecure plugins or add-ons are being used.

Cloud-based storage and mobile apps increase the presence of stored data online, which increasingly leads to new threat vectors like cloud-based botnets and more.

The key is for businesses to prioritize security and invest in platforms and solutions that will help protect customer and business data. Critical in this effort is the implementation of IT best practices in regularly updating operating system and application software, limiting the access users have for installing or modifying software on their devices, and always monitoring the systems for vulnerabilities.

Like cybersecurity and retailers, Noobeh and secure IT go together. We help retail and other businesses proactively address cybersecurity challenges so they can protect both their business and their customers.

Prey or Empowered? Small Businesses and IT Security

Now more than ever, small businesses need to be vigilant with their information technology security. Small businesses may not be the big fish in the sea, but there are plenty of them out there to catch. Small businesses tend to make the best targets because they often fail to perform security audits, they may not be willing to invest in the resources needed to protect themselves, and they frequently don’t even carry the right insurance coverages. To hackers, small businesses are easy prey.

“Don’t think you are too small to be affected,” says Erik Knight, the founder and CEO of SimpleWAN. “Every place you have an employee or office is a potential entry point. Take it seriously; if you have something worth taking, a hacker will try to take it.”

https://www.forbes.com/…

There are a few things every business can do to improve the security and privacy of their data. It isn’t an option any longer; these are essential elements in an overall security strategy that can make the difference between staying in business and not.

Use strong passwords, not easy-to-guess words, phrases or sequences (1234 is not a strong password). Passwords should be unique, more than 8 characters in length, and have a mix of numbers, letters, and special characters.

Keep software updated. Whether it is the operating system on your computer or the software you use to write letters, having up-to-date software matters. Developers don’t just upgrade software to fix bugs or introduce new features; software often gets updated because of security issues or vulnerabilities.

Keep networks and connected devices secure to make sure that the computers and connections aren’t introducing weaknesses into your system. Not only are password controls and software updates needed, but firewall security and good anti-virus/anti-malware solutions are also a must. Keeping an eye on the server matters, but the connecting points and end points are where many vulnerabilities exist.

Set up two-factor or multi-factor authentication to further secure logins. 2FA and MFA is like having ID besides just your driver’s license to prove you are who you say you are. Your password, like your DL, is just one factor; you need one more thing to prove your identity for 2FA, like a code from your phone or maybe your fingerprint. The point is that there should be more than just a username and password to access important data.

Restrict use of personal email or social media on work devices. This gets a little trickier with smaller businesses, as many don’t or can’t support providing users with all company-owned devices. There are tradeoffs to allowing users to bring their own devices (byod) versus using company-owned devices. When mobile devices are part of the mix along with desktop and portable computers, it becomes even more complicated and the risk potential increases.

Use encryption for data in transit and data at rest. Encryption is like scrambling the data and then unscrambling it when you access it. In transit, data may be encrypted by a VPN so that it is protected over the wire (in motion) as it is sent and received on the network. RDP is also encrypted, but this remote access method’s main purpose is to keep the data from leaving the server in the first place. At rest, like when it is sitting on a hard drive or other storage location, data can also be encrypted. To open the file or file system, you need a key to decrypt it.

Keep all data backed up and create a way to rapidly recover your server and systems in the event of failure or compromise. Backups are great right up until you find they are as damaged or unrecoverable as your main system, so make sure to have a policy of testing your backups periodically. There are many ways to back up and protect your data, including external drives and cloud storage. If data gets lost or corrupted, you want to be able to restore it from a backup. Regularly audit your backup and data security practices to help identify weaknesses that make the business vulnerable.

Educating employees on the importance of cyber security is among the most important steps a business can take to protect itself. Keeping passwords secure and secret, knowing how to spot a phishing email and what to do and not do with it, not clicking on suspicious links in emails, not sharing personal or confidential information online, and what to do in the event of a breach are all things that should be regularly discussed with workers and supported by written policies.

Managed Azure cloud servers from Noobeh help you keep your business information more secure. Our services demand high levels of security and privacy, and we help our customers keep their data and systems safer and more secure by handling some of the requirements for them.

  1. Strong password policies and MFA is our standard setup, and software updates and patching are part of the service.
  2. Working on the cloud server keeps data on the server and not traversing the network or downloading to individual PCs, so information stays secure and separate from whatever a user runs on their local devices.
  3. Data on the Azure virtual machines is encrypted at rest, and additional encryption is available to add more layers of protection. Data in motion is encrypted, but very little data actually traverses the wire.
  4. Servers and data are backed up regularly with snapshots and file level backups, allowing for simple file restores as well as comprehensive system recovery.

For small businesses, Noobeh has the solution for creating a more secure and better protected IT environment where applications and data can be available to those who need them without compromising the investments already made in training and process development. Moving software and data to a private cloud server allows companies to continue using the software they rely on, just in a better way. Instead of being easy prey to hackers, our customers benefit from higher levels of IT administration, management and protection that empowers them to work the way they need to – any time, anywhere.

QuickBooks Desktop Enterprise 2024 Security Improvements: Now with 256-bit encryption

Intuit’s release of QuickBooks Enterprise and other desktop editions for 2024 have a variety of new features, and among them is an improved level of security for your business data. Upgrading from 128-bit encryption, QuickBooks Desktop 2024 now has AES 256-bit encryption.

256-bit encryption is the strongest and most robust encryption standard commercially available. It’s widely used because it’s virtually impenetrable to brute-force attacks. 256-bit encryption is an encryption technique that uses a 256-bit key to encrypt and decrypt data. Plain text is converted to a cipher, and the encryption key is required to decrypt the data and return it to readable plain text.

256-bit encryption is used in most modern encryption algorithms, protocols, and technologies, including AES in wireless security, processor security, file encryption, and SSL/TLS.

According to Intuit, “You can be confident your data is protected with our enhanced security using industry-leading AES 256-bit encryption. QuickBooks safeguards your reputation by protecting critical customer and vendor data, such as business financials, banking information, and credit card details.

This means we translate your information into a code that only we can read to make sure only you and Intuit have access to your information. The type of encryption we use is called AES-256 (Advanced Encryption Standard with 256-bit keys) and it ensures the highest level of cryptographic security.”

With a series of robust security steps and a complex 256-bit decryption key, AES 256-bit standard is nearly impossible to break using brute-force methods and has been approved for the handling of confidential data by the U.S. Government.

A brute force attack is when a hacker tries different combinations until they arrive at the correct combination – the key. The larger the key size, the more difficult it becomes to break the encryption. We’re talking about 256-bit keys. There are 984,665,640,564,039,457,584,007,913,129,639,936 (that’s 78 digits) possible combinations. Even if you use Tianhe-2 (MilkyWay-2), which was the 4th fastest supercomputer in the world in 2022, it will take millions of years to crack 256-bit AES encryption.

In case you’re interested: The fastest supercomputer in the world, ranked in June 2023, is Frontier, an HPE Cray EX system run by the US Department of Energy, Frontier incorporates 3rd Gen AMD EPYC™ CPUs representing 8,730,112 cores that have been optimized for high-performance computing (HPC) and AI with AMD Instinct™ 250X accelerators and Slingshot-11 interconnects. Its HPL benchmark was 1.194EFLOPS (EXA – 1 quintillion – floating point operations per second). (via networkworld.com). Frontier is faster than Tianhe-2, so breaking the key could take a little less time.

Breaking encryption with no known flaws is kind of like guessing a password. If you make enough guesses, you might eventually get the password right. With strong encryption, this can take a long time. AES-256 is the most secure version of AES and is virtually unbreakable by brute force based on current computing power. It’s also considered quantum-resistant, which means that quantum computers aren’t expected to crack the cipher.

How long would it take to crack 128-bit encryption using a brute force attack? Most security professionals would answer “1 billion years”, but that’s just an estimate. A machine that can crack a DES key in a second would take about 149 trillion years to crack a 128-bit AES key. According to researchers, with the right quantum computer, AES-128 would take about 2.6110^12 years to crack, while AES-256 would take 2.2910^32 years. For reference, the universe is currently about 1.38×10^10 years old, so cracking even an AES-128 encryption with a quantum computer could take hundreds of times longer than the universe is believed to have existed.

While Intuit is improving the security of the information it stores and transmits between its systems, your company should be equally concerned with the security and protection of all your business applications and data. Using strong password policies, multi-factor authentication, and SSL for secure web app access, Noobeh’s QBonAzure services provide layers of protection on top of the $20Bn in security investments made by Microsoft.

We take data security seriously, providing solutions to address access, security, privacy and protection for business applications and data. When your QuickBooks Enterprise deployment needs a solid foundation that offers agility and performance as well as strong platform security, we have that.

The Question You Never Want to Have to Ask

Why MFA Shouldn’t Be Optional

“Do you offer any help for decrypting files due to ransomware?”

This is a question we are asked with more frequency than ever before. And, sadly, it is often followed up with the information that their files were on “an internal server that was missed in the backup protocol by IT”.

Email phishing and brute force attacks are the most common methods cyber criminals use to get into your business network where they can set up to initiate ransomware attacks. The ransomware (malware) encrypts your data, which becomes unrecoverable without the decryption key. Usually, the only way to recover from a malware/ransomware attack is to rebuild systems and restore data from backups. If you have backups.

A “brute force” attack is typically used to get personal information such as passwords or passphrases, usernames, and Personal Identification Numbers (PINS). Scripts or specialized apps are used to carry out a string of continuous attempts to get the information desired. Cybersecurity researchers at Coveware analyzed ransomware attacks during the second quarter of 2021 and found that phishing and brute force attacks on unsecured desktops (remote and local) are among the most popular entry points for starting ransomware attacks. This is at least partly because it is relatively cheap and can be highly effective.

Phishing attacks are when cyber criminals send emails containing a malicious file attachment or hyperlink directing to a compromised website that delivers ransomware. Attacks against desktop logins include methods where cyber criminals use brute force to leverage weak or default usernames and passwords – or even get access because they got legitimate login credentials via a phishing email.

Software vulnerabilities and web-based application services are also among the popular vectors for delivering ransomware or exposing corporate networks to cyber criminals. While this type of attack is somewhat less frequent than the others, they are often leveraged by some of the most sophisticated and disruptive ransomware groups and nation/state bad actors.

  • Sodinokibi – also known as REvil – is responsible for some of the most high-profile ransomware attacks this year, including the massive ransomware attack on customers of Kaseya.
  • Contij – one of the most high-profile attacks by the group was the attack against the Irish healthcare system. Healthcare services across Ireland remained disrupted for months.
  • Avaddon – ransomware distributed via phishing emails.
  • Mespinoza and Hello Kitty are new forms of ransomware recently identified.

All of these have a common purpose in that they take advantage of weaknesses in security and exploit phishing tactics to lay the foundation for an attack on your network and possibly others.

Keeping systems updated, applying security patches and application software updates is an important aspect to keeping things secure. Known vulnerabilities can be exploited to gain access to the network, so keeping up with updates as the vendor supplies them has become more important than ever.

To help protect networks from being compromised, businesses should also apply multi-factor authentication (MFA) to desktop and applications.

MFA is an important tool to help stop intruders from breaching accounts and gaining access to the corporate network, and it can be the difference between keeping your data safe and working or discovering your files are digitally encrypted and completely unusable. Data encryption changes the data into code, and only the decryption key can read the code and return the data to a useable form. If you don’t have the key, the data typically cannot be decrypted.

Cyberattacks continue to evolve in their sophistication and frequency, and consequences of such attacks are growing. Private companies and public agencies alike must adapt their security techniques and embrace new security technologies while providing more end-user education and training.

Mendelson Consulting and NOOBEH Cloud Services take security very seriously and we have the experience and expertise to assist businesses with transforming their operations to be more efficient and effective. Our cloud team works exclusively with private tenant accounts on Microsoft Azure, and offers MFA security and other solutions to protect local and remote resources, helping keep your valuable information safe and available when you need it.

“How can we get started?” is the question you should be asking.
