When we think of cyber threats to endpoints, typically what comes to mind is the need to protect our PC’s and laptops. Many more businesses are adding comprehensive security solutions and user policies administered to include mobile threat exploits.
But it’s unquestionable now that mobile phones are just as likely (if not more likely) to be targeted by cyber criminals. There are a few reasons for that. The first reason that mobiles are now a legitimate target is the sheer number of them. It’s estimated that there will be over 6 billion smartphones in use by the year 2020. That’s around 70% of the world’s population using a smartphone in 3 years’ time.
Modern smartphones are now small computers. The processing power, functionality, and the way we’ve integrated them into our lives make them a treasure trove of valuable information and easy food for hackers wishing to use mobile threat exploits. And IoT Botnets further increases the vulnerability of cloud based data and mobile devices.Many people today use their mobile phones to access online banking and as a physical payment method in store. Cybercriminals tend to follow the money and so are putting resources into targeting mobiles. Last year, security vendor ESET discovered a form of malware that presented a false version of online banking login screens to steal credentials.
Exposing Vulnerabilities of Mobile Threat Exploits
Like any operating system, there is a continual process of discovering vulnerabilities and attempting to patch them before hackers can take advantage.
This can be complicated on the Android OS. Android is open source, allowing stakeholders to modify and redistribute it to fit their needs.
This means that when mobile threat exploits and vulnerabilities are fixed at the source, it doesn’t always translate to the problem being resolved for the user.
The most famous example of this is the Stagefright vulnerability. This was mobile threat exploits in the code library associated with media playback. If a hacker sent malicious code within a video via MMS, the attack could be successful without any interaction from the user. This vulnerability was said to affect 95% of Android users making patching a nightmare. Although there had been previous serious vulnerabilities in Android, such as FakeID, TowelRoot, and PingPong, this was the first exploit of this scale that could be successful without any user input.
No OS is Safe
Typically, we see most of mobile attacks targeted at Android devices. But iOS is not completely bulletproof. XcodeGhost was a copycat version of Apple’s development environment, used for creating apps. Developers that used the rogue version of Xcode to create their apps unwittingly delivered their product to the App Store with the malware in tow.
Mobile Threat Exploits Protection Starts with Education
So clearly, we need a robust plan in place to protect mobile devices from mobile threat exploits. But how do we go about this? The first thing to consider is user education. When using a laptop, most people know not to open attachments from unknown sources. But mobile users are not always as careful. Educate them to apply this same level of caution to mobiles; only downloading apps from trusted sources and giving the application, the minimum permissions required to perform its task.
Management is Not Security
Your company likely already has an Enterprise Mobility Management (EMM) solution in place. This is useful for managing a fleet of mobiles and preventing opportunistic crimes by enforcing passcodes, for example. But EMM is not sufficient to protect against more advanced threats, and most suites don’t have the functionality to detect, analyze and respond to cyber attacks. For this reason, it’s important to supplement your EMM with a Mobile Threat Defense (MTD) product.MTD has far greater mobile threat exploits threat-detection capabilities and can help to prevent man-in-the-middle attacks, detect non-compliant or malicious apps, and spot jailbroken devices. It’s important to have this level of security on your mobile devices due to the amount of corporate data that can typically be accessed via mobile now.
User-Based Access Controls
A cloud-based Identity as a Service (IDaaS) solution can also help to increase security. The benefits of this to a business are two-fold: For the user, all their corporate systems can be accessed via a single sign-on (SSO). This eliminates the need to remember multiple login credentials.It’s likely to be a multifactor sign-on process which is more secure than a static password. IDaaS also allows users to be automatically granted certain access rights or privileges based on their role. Employees get the right tools to complete their job function and no more. This means that in the event of a mobile threat exploits, the compromise, the amount of accessible information can be limited.
As mentioned, patching mobile devices is not always straightforward, particularly in Android ecosystems. Updates can be blocked by Google, the handset manufacturer, or the mobile operator. However, this situation has improved since Stagefright. Even given these difficulties, it’s important that you have a process for keeping your operating systems up to date. This should be easy to configure in your EMM solution.Ultimately, we don’t need the statistics to tell us that mobiles are here to stay in the business world; we see evidence of this every day. Mobiles are now integral to huge chunks of our working lives. And because of this, the threat from hackers will continue to grow.
What steps are you taking to ensure that mobiles aren’t an easy attack vector into your business? And do you feel that your users are as educated on mobile threat exploits as they are about conventional PC-based malware?
