1. Social Engineering
Social engineering attacks are when bad actors send fake emails (phishing attacks) or text messages (smishing attacks) to your employees in an effort to trick them into handing over private information like their passwords or downloading malware onto their devices.
Phishing Attack Countermeasures
The best defense for phishing and other social engineering attacks is to teach employees how to spot phishing emails and SMS messages that look suspicious and avoid falling prey to them altogether. Reducing the number of people who have access to sensitive data or systems can also help protect your organization against social engineering attacks because it reduces the number of access points attackers have to gain access to critical systems or information.
2. Data Leakage via Malicious Apps
Today, hackers can easily find an unprotected mobile app and use that unprotected app to design larger attacks or steal data, digital wallets, backend details, and other juicy bits directly from the app.
For example, when your employees visit Google Play or the App Store to download apps that look innocent enough, the apps ask for a list of permissions before people are allowed to download them. These permissions generally require some kind of access to files or folders on the mobile device, and most people just glance at the list of permissions and agree without reviewing them in great detail.
However, this lack of scrutiny can leave devices and enterprises vulnerable. Even if the app works the way it’s supposed to, it still has the potential to mine corporate data and send it to a third party, like a competitor, and expose sensitive product or business information.
How to Protect Against Data Leakage
The best way to protect your organization against data leakage through malicious or unsecured applications is by using mobile application management (MAM) tools. These tools allow IT admins to manage corporate apps (wipe or control access permissions) on their employees’ devices without disrupting employees’ personal apps or data.
3. Unsecured Public WiFi
Public WiFi networks are generally less secure than private networks because there’s no way to know who set the network up, how (or if) it’s secured with encryption, or who is currently accessing it or monitoring it. And as more companies offer remote work options, the public WiFi networks your employees use to access your servers (e.g., from coffee shops or cafes) could present a risk to your organization.
For example, cybercriminals often set up WiFi networks that look authentic but are actually a front to capture data that passes through their system (a “man in the middle” attack). Here’s what that looks like:
If this seems far-fetched, it isn’t. Creating fake WiFi hotspots in public spaces with network names that look completely legit is incredibly simple, and people are very willing to connect, as shown by experiments run at the Democratic and Republican conventions in 2016 and by an experiment run by a researcher in 2019 from Magic.
How to Reduce Risks Posed By Unsecured Public WiFi
The best way for you to protect your organization against threats over public WiFi networks is by requiring employees to use a VPN to access company systems or files. This will ensure that their session stays private and secure, even if they use a public network to access your systems.
4. End-to-End Encryption Gaps
An encryption gap is like a water pipe with a hole in it. While the point where the water enters (your users’ mobile devices) and the point where the water exits the pipe (your systems) might be secure, the hole in the middle lets bad actors access the water flow in between.
Unencrypted public WiFi networks are one of the most common examples of an encryption gap (and it’s why they’re a huge risk to organizations). Since the network isn’t secured, it leaves an opening in the connection for cybercriminals to access the information your employees are sharing between their devices and your systems.
However, WiFi networks aren’t the only thing that poses a threat—any application or service that’s unencrypted could potentially provide cybercriminals with access to sensitive company information. For example, any unencrypted mobile messaging apps your employees use to discuss work information could present an access point for a bad actor.
Solution: Ensure Everything is Encrypted
For any sensitive work information, end-to-end encryption is a must. This includes ensuring any service providers you work with encrypt their services to prevent unauthorized access, as well as ensuring your users’ devices and your systems are encrypted as well.
5. Internet of Things (IoT) Devices
The types of mobile devices that access your organization’s systems are branching out from mobile phones and tablets to include wearable tech (like the Apple Watch) and physical devices (like Google Home or Alexa). And since many of the latest IoT mobile devices have IP addresses, it means bad actors can use them to gain access to your organizations’ network over the internet if those devices are connected to your systems.
How to Combat Shadow IoT Threats
Mobile device management (MDM) tools can help you combat shadow IoT threats, as well as identity and access management (IAM) tools like Auth0. However, IoT/Machine-to-Machine (M2M) security is still in a bit of a “wild west” phase at the moment. So it’s up to each organization to put the appropriate technical and policy regulations in place to ensure their systems are secure.
Spyware is used to survey or collect data and is most commonly installed on a mobile device when users click on a malicious advertisement (“malvertisement”) or through scams that trick users into downloading it unintentionally.
Whether your employees have an iOS or Android device, their devices are targets ripe for data mining with spyware—which could include your private corporate data if that device is connected to your systems.
How to Protect Against Spyware
Dedicated mobile security apps (like Google’s Play Protect) can help your employees detect and eliminate spyware that might be installed on their devices and be used to access company data. Ensuring your employees keep their device operating systems (and applications) up to date also helps ensure that their devices and your data are protected against the latest spyware threats.
7. Poor Password Habits
A 2020 study by Balbix found that 99% of the people surveyed reused their passwords between work accounts or between work and personal accounts. Unfortunately, the passwords that employees are reusing are often weak as well.
For example, a 2019 study by Google found that 59% of the people they surveyed used a name or a birthday in their password, and 24% admitted to using a password like one of these below:
These bad password habits present a threat to organizations whose employees use their personal devices to access company systems. Since both personal and work accounts are accessible from the same device with the same password, it simplifies the work a bad actor has to do in order to breach your systems.
However, these behaviors also provide opportunities for credential-based brute force cyberattacks like credential stuffing or password spraying because cybercriminals can use weak or stolen credentials to access sensitive data through company mobile apps.
How to Reduce or Eliminate Mobile Password Threats
The NIST Password Guidelines are widely regarded as the international standard for password best practices. Following these guidelines—and insisting your employees do the same—will help protect you against threats from weak or stolen passwords. Password managers can simplify the work required for your employees to follow these guidelines.
Requiring your employees to use more than one authentication factor (multi-factor authentication or MFA) to access mobile company applications will also help reduce the risk that a bad actor could gain access to your systems since they’d need to verify their identity with additional authentication factors in order to log in.
Finally, implementing passwordless authentication will help you eliminate password risks altogether. For example, in the event that a mobile device is stolen or accessed illegally, requiring a facial scan as a primary (or secondary) authentication factor could still prevent unauthorized access.
8. Lost or Stolen Mobile Devices
Lost and stolen devices aren’t a new threat for organizations. But with more people working remotely in public places like cafes or coffee shops and accessing your systems with a wider range of devices, lost and stolen devices pose a growing risk to your organization.
How to Protect Against Lost or Stolen Device Threats
First and foremost, you’ll want to ensure employees know what steps to take if they lose their device. Since most devices come with remote access to delete or transfer information, that should include asking employees to make sure those services are activated.
Mobile device management (MDM) tools can also help you secure, encrypt, or wipe sensitive company information from a device that’s lost or stolen, so long as those tools were installed before the device went missing.
9. Out of Date Operating Systems
Like other data security initiatives, mobile security requires continuous work to find and patch vulnerabilities that bad actors use to gain unauthorized access to your systems and data.
Companies like Apple and Google address a lot of these vulnerabilities with operating system updates. For example, in 2016, Apple realized it had three zero-day vulnerabilities that left its devices open for spyware attacks and released a patch to protect users against these vulnerabilities.
However, these patches only protect your organization if your employees keep their devices up to date at all times. And according to Verizon’s Mobile Security Index Report, operating system updates on 79% of the mobile devices used by enterprises are left in the hands of employees.
How To Keep Mobile Operating Systems Up To Date
Google and Apple both allow organizations to push updates to managed Android and iOS devices. Third-party MDM tools (for example, Jamf) often provide this functionality as well.
IAM Tools Can Help Secure Company Mobile Applications
Identity and Access Management (IAM) tools can help organizations secure the apps and data that users access from their mobile devices, including:
- Restricting which devices and users can access enterprise applications and data, as well as which parts of those applications they’re allowed to access.
- Tracking user behavior and securing access in the event that something looks suspicious with security features like multi-factor authentication (MFA),brute force attack protection, and more.
