Why MFA isn’t foolproof: How to strengthen your security

Multifactor authentication (MFA) significantly enhances your business’s security, but it’s not invincible. Cybercriminals have found ways to exploit MFA’s weaknesses, and understanding these is essential for safeguarding your business. This article will guide you through common MFA hacks and provide preventive strategies.

How cybercriminals bypass MFA

Cybercriminals use a variety of techniques to compromise MFA systems.

MFA fatigue

MFA fatigue, also known as push bombing, occurs when cybercriminals flood users with numerous authentication requests, often through push notifications. Overwhelmed by the constant bombardment, users may accidentally or out of frustration approve one of the requests, unwittingly giving cybercriminals access. A notable example of this occurred in 2022 when cybercriminals targeted Uber’s external contractor, repeatedly sending MFA requests until access was granted.

Phishing

In a phishing attack, cybercriminals pose as legitimate entities such as banks or IT support, and send deceptive messages that prompt users to provide their MFA codes. These messages often contain a sense of urgency such as a warning of an account breach or a required security update to pressure users into acting without verifying the authenticity of the request. Once the cybercriminals have the MFA code, they can use it to bypass security systems and gain unauthorized access to accounts or sensitive data.

SIM swapping

Mobile devices are often used as a primary means of receiving MFA codes, making them a prime target for cybercriminals. In a SIM swapping attack, a cybercriminal convinces a mobile carrier to transfer a victim’s phone number to a new SIM card that they control. Once successful, the cybercriminal intercepts MFA codes sent via SMS, allowing unauthorized access to the victim’s accounts.

Strategies to prevent MFA attacks

To protect your organization from MFA hacks, follow these strategies:

Use risk-based authentication

Implement risk-based authentication that dynamically adjusts security requirements based on user behavior. For example, if a user logs in from an unusual location or unknown device, the system can automatically require additional verification. This adaptive approach helps prevent attacks by raising security standards when necessary.

Implement hardware-based MFA

Hardware security keys such as those that use Fast Identity Online (FIDO) protocols, provide stronger protection than software-based MFA. These physical devices generate unique authentication codes, making them much harder to intercept or duplicate. Consider using hardware-based MFA for highly sensitive applications to enhance your security posture.

Regularly review access rights

Grant users only the access they need. Regularly audit user permissions to ensure employees have access only to the data and systems necessary for their roles. This limits the potential damage a compromised account can cause, reducing the overall risk to your business.

Strengthen password reset processes

Password reset procedures can be a weak link in MFA systems. Make sure your reset processes require users to verify their identity through more than one channel. This additional layer of security can prevent cybercriminals from exploiting reset processes to gain unauthorized access.

Monitor high-value targets

Certain users, such as system administrators and legal or HR personnel, possess elevated privileges that make them attractive to attackers. Pay close attention to the MFA protections surrounding these accounts and implement the strictest security measures.

Stay ahead of emerging threats

Cybercriminals are constantly evolving their tactics. To ensure your systems remain resilient, keep a close eye on new attack methods and vulnerabilities, and proactively update your security measures to counter these threats.

Implementing these strategies can help you significantly bolster your company’s defenses against MFA attacks and safeguard valuable assets from unauthorized access.

3 Security advantages of the Cloud

Small and medium-sized businesses (SMBs) no longer need to view cybersecurity as an insurmountable challenge. Cloud technology has transformed the security landscape, providing SMBs with access to enterprise-level solutions without having to maintain extensive in-house IT infrastructure or staff. Here are three security advantages the cloud offers over traditional IT setups

Access to specialized expertise

For SMBs, limited in-house resources often force IT staff to juggle multiple technologies and responsibilities, which compromises cybersecurity quality. No matter how skilled, a small tech support team cannot master every necessary service or solution, and if they focus solely on cybersecurity, other critical areas such as hardware maintenance and help desk services suffer.

In contrast, cloud service providers (CSPs) operate on a larger scale. They manage numerous servers with large teams composed of specialists for every aspect of cloud technology, including cybersecurity. This means you can fully secure your IT without compromising any other aspect of your operations.

Fewer vulnerabilities

In a traditional IT infrastructure, all aspects of your business’s IT are consolidated in one location, which can increase your vulnerability to various cyberthreats and emergencies.

For example, a server on the same network as workstations can be compromised if an employee inadvertently downloads malware. This risk extends to physical security as well; without proper cybersecurity training, employees are more likely to create vulnerabilities, such as unsecure server rooms, unlocked workstations, or poorly designed and protected passwords.

In contrast, CSPs configure their networks to reduce access points and ensure that all personnel are well trained in cybersecurity. These factors combine to minimize security risks.

Built-in business continuity

Cloud storage offers significant advantages for business continuity during unforeseen events. Its geographically distributed infrastructure creates a natural barrier between your local network and data backups. This physical separation protects against malware that rapidly self-replicates across connected devices, such as worms. By storing backups in the cloud, you create an isolated copy of your data, reducing the risk of infection.

In addition to cyberthreats, cloud storage also safeguards your data from physical disasters such as fires, floods, or power outages. In such scenarios, the cloud ensures continued access to critical information. This means employees can seamlessly resume operations from any remote location with an internet connection, minimizing downtime and disruptions.

More than improved security

Beyond secure data storage, cloud computing now offers a vast array of customizable software, powerful platforms, and on-demand services. These options give businesses access to the exact tools they need, all within a secure and managed environment.

Let us help you unlock the full potential of the cloud and streamline your operations.

Essential cybersecurity tips for small businesses

Cyberattacks target businesses of all sizes. While large corporations often grab headlines, small businesses are increasingly becoming prime targets due to their often weaker security defenses. Fortunately, by following the tips in this article, you can enhance your business’s cybersecurity posture.

Secure your cloud storage

Cloud storage provides a convenient and cost-effective solution for storing data. However, not all cloud providers prioritize security. To protect your sensitive information, select a reliable platform that offers strong encryption and access controls.

Fortify your network

Your network is the backbone of your business operations, connecting all company devices such as computers, printers, smartphones, and routers. Unfortunately, all connected devices can be entry points for cybercriminals.

To protect your network, use strong, unique passwords for every device and enable multifactor authentication (MFA) whenever possible. MFA adds another layer of security by requiring multiple forms of verification such as a password and a code sent to your phone.

Moreover, you should secure your Wi-Fi network with a robust password and create a separate guest network for visitors. Ensure your Wi-Fi is encrypted with the latest standard, WPA3, to prevent unauthorized access.

Invest in extra security tools

Bolstering your business’s digital defenses requires more than just basic security measures. Consider implementing these additional tools:

  • Virtual private network – creates a secure, encrypted connection between your devices and the internet
  • Firewall – monitors incoming and outgoing traffic and blocks suspicious activity
  • Intrusion detection and prevention systems – monitor network traffic for suspicious activities and block such activities in real time
  • Email security – detects and blocks malicious emails
  • Data loss prevention – keeps sensitive data from being accidentally or maliciously shared outside your organization

Keep software up to date

It’s tempting to ignore those software update notifications, but doing so can leave your system vulnerable. Software updates often include patches that plug security holes that cybercriminals can exploit. By promptly installing updates, you can strengthen your defenses.

Back up company data

Ransomware attacks are a serious business threat. They encrypt critical data, holding it hostage until a ransom is paid. Implementing a robust backup strategy is crucial for protecting your data and minimizing disruption if you suffer a ransomware attack.

Limit employee access to the company network

Believe it or not, many cyberattacks start from within a company. To minimize the damage caused by an insider threat, grant employees only the necessary permissions to perform their job functions. Regularly review and adjust employee permissions, and promptly revoke access when employees leave the company.

Educate your team

Many cyberattacks happen because employees make mistakes. They might click on a suspicious email, give away their password, or use weak passwords.

To prevent human error, train staff to recognize and avoid common cyberthreats, create strong passwords, and handle sensitive information securely. Conducting regular cybersecurity training and cyberattack simulations can reduce the risk of breaches.

Create a security culture

Cybersecurity shouldn’t be solely the IT department’s responsibility but rather every employee’s. Involve employees in security initiatives and encourage them to report suspicious activities. By fostering a company-wide security culture, you can create a stronger and more resilient organization.

These steps might seem simple, but they go a long way in safeguarding your business from cyberattacks.
