Understanding these threats and implementing robust security measures can make a substantial difference in safeguarding your enterprise’s mobile infrastructure. 

Whether you manage your mobile security internally or leverage the expertise of a enterprise expense management provider like Tellennium that offers managed mobility services, this article will provide valuable insights to enhance your organization’s mobile security strategy.  

Let’s review in greater detail to provide a clearer picture of the mobile security landscape in 2024 and actionable strategies to protect your enterprise from these emerging threats.

4 More Critical Mobile Security Threats to Monitor This Year

1. SIM Swap Attack

SIM swap attacks have become a significant threat in the mobile security landscape. These attacks involve the fraudulent transfer of a victim’s mobile phone number to a new SIM card controlled by the attacker, allowing them to intercept calls and messages, including two-factor authentication (2FA) codes, and gain access to sensitive accounts. 

The frequency and sophistication of SIM swap attacks have increased dramatically. Attackers often use social engineering techniques to convince mobile carrier employees to issue a new SIM card, thereby gaining control over the victim’s phone number. Once they have access, they can intercept 2FA codes sent via SMS, allowing them to bypass security measures on banking, email, and other sensitive accounts. 

To combat this threat, various things can be done. At Tellennium, for example, we implement robust security measures and monitoring processes. Our technology platform / system encrypts all passwords and logs user activity, IP addresses, and session details to ensure secure access.  

Additionally, we’ll undergo regular security testing and are SOC2 Type 2 and PCI Certified, ensuring compliance with industry standards for data protection. The system monitors network servers and services for vulnerabilities 365 days a year, including intrusion detection, malware scanning, and virus protection. 

Despite these efforts, detecting and preventing SIM swap attacks can be challenging due to the sophisticated social engineering tactics used by attackers. The quick execution of these attacks leaves little time for response, making it essential to have robust preventive measures in place. 

To mitigate the risk of SIM swap attacks, consider the following strategies: 

  • Enhanced Verification: Implement multi-step verification processes for SIM card changes to ensure authenticity. 
  • Alert Systems: Set up alert systems to notify users of SIM card changes, allowing for immediate action if unauthorized activity is detected. 
  • Account Recovery: Ensure robust account recovery mechanisms to quickly regain control in case of a SIM swap. 

By incorporating these strategies, your enterprise can significantly reduce the risk of SIM swap attacks and protect sensitive information from unauthorized access.

2. Mobile Ransomware

Mobile ransomware is a type of malware that encrypts data on mobile devices, demanding a ransom for its release. This threat is particularly dangerous as it can lead to the loss of sensitive personal and business data, disrupt operations, and cause significant financial losses. 

Ransomware typically spreads through malicious apps or phishing links that trick users into downloading the malware. Once installed, the ransomware encrypts files on the device, rendering them inaccessible until a ransom is paid. The attackers often demand payment in cryptocurrency to make it difficult to trace the transaction. 

To combat mobile ransomware, for example, Tellennium implements robust application security protocols. These include the confidentiality of client information, secure schemas for each instance, enterprise-class anti-virus, email-based Data Loss Prevention (DLP) policies, malware protection, redundant firewalls, and Intrusion Detection/Prevention Systems (IDS/IPS).  

We’ll also support client authentication through Single Sign-On (SSO) and SAML protocols, ensuring secure access to mobile applications. All data is encrypted at rest and in transit, providing an additional layer of security. 

Despite these measures, the recovery from a ransomware attack can be challenging. Paying the ransom does not guarantee that the encrypted data will be restored, and there is always the risk of further extortion. Therefore, prevention is the best strategy. 

To protect against mobile ransomware, consider the following strategies: 

  • Regular Backups: Maintain regular backups of mobile data to mitigate the impact of an attack. Ensure that backups are stored securely and are not connected to the main network. 
  • App Scrutiny: Only download apps from trusted sources, such as official app stores, and scrutinize app permissions before installation. 
  • Anti-Ransomware Tools: Use mobile security solutions that offer ransomware protection, including real-time scanning and threat detection. 
  • User Education: Educate employees about the risks of downloading unknown apps and clicking on suspicious links. Regular training can help users recognize and avoid potential threats. 

By leveraging these strategies your enterprise can significantly reduce the risk of mobile ransomware attacks and ensure that sensitive information remains secure.

3. Mobile Device Theft and Loss

Theft or loss of mobile devices poses a significant risk to organizations, as it can lead to unauthorized access to sensitive information and disrupt business operations. Given the portability and value of mobile devices, they are prime targets for thieves. 

Statistics indicate that a substantial number of mobile devices are lost or stolen each year, potentially exposing confidential data. The impact of such incidents can be severe, leading to data breaches, financial losses, and compromised personal information. 

To mitigate the risks associated with mobile device theft and loss, organizations should implement comprehensive security measures. Tellennium, as an example, supports these efforts by offering solutions such as remote wipe capabilities.  

In the event a device is lost or stolen, the ability to remotely wipe the device ensures that sensitive information is protected. Additionally, monitoring mobility lines daily to prevent bill shock and optimize savings by adjusting plans based on current usage is a sound practice. 

Here are strategies to protect against mobile device theft and loss: 

  • Device Encryption: Encrypt data on mobile devices to protect information even if the device is lost or stolen. 
  • Remote Wipe: Enable remote wipe capabilities to erase data from lost or stolen devices. 
  • Strong Authentication: Use strong authentication methods, such as biometrics and robust passwords, to prevent unauthorized access. 
  • Tracking and Recovery Tools: Utilize tracking and recovery tools to locate lost or stolen devices and recover them if possible. 

By incorporating these strategies along with a proactive approach to mobile security, your enterprise can reduce the risks associated with mobile device theft and loss, ensuring that sensitive information remains protected and business operations are not disrupted.

4. Application Vulnerabilities

Mobile applications, particularly those not sourced from official app stores, can contain vulnerabilities that expose devices to various security risks. These vulnerabilities can lead to unauthorized access, data leakage, and exploitation by attackers. 

Many mobile applications are designed with minimal security features, making them prime targets for cyberattacks. Poorly coded apps can be exploited to gain unauthorized access or control over devices.  

Additionally, vulnerable apps can serve as entry points for attackers to infiltrate larger network infrastructures, compromising not only individual devices but also the entire enterprise network. 

At Tellennium, we’ll work to mitigate these risks by ensuring the security of mobile applications for our clients through various processes and measures. These include deploying enterprise-class anti-virus, Data Loss Prevention (DLP) policies, and malware protection tools to secure mobile applications.  

Supporting client authentication, such as Single Sign-On (SSO) and SAML protocols, and encrypting all data at rest and in transit, further enhances security. 

Here are strategies to secure mobile applications: 

  • Official App Stores: Download apps exclusively from official app stores where they undergo rigorous security checks. 
  • Code Review: Conduct thorough code reviews and security assessments of custom-developed apps. 
  • App Security Tools: Utilize mobile security tools that scan for vulnerabilities and protect against malicious activities. 
  • Regular Updates: Ensure all applications are regularly updated to patch any known vulnerabilities. 

By adopting these strategies, along with leveraging comprehensive security measures, your organization can significantly reduce the risk of application vulnerabilities and protect sensitive data from potential breaches.
