Top 5 Mobile Security Threats

COVID-19 has made us rethink the way we work, adjusting how we socialise, and adapting to contact tracing regulations. With a new reliance on our mobile devices in multiple aspects of our lives, mobile security vulnerabilities, exploits, and threats have evolved significantly during the pandemic.

There have been numerous reported cases of fake, malicious mobile applications imitating contact tracing applications that give attackers access to smartphone data or encrypt devices for ransom. With mobile devices and apps becoming increasingly important in a contactless world, they have started receiving extra attention from cybercriminals. As a result, cyber threats against mobile devices have gotten more diverse. Let’s look into the types of mobile security threats and how you can protect yourself and your loved ones.

Top Mobile Security Threats

1. Malicious applications & websites

Mobile malware has grown more prevalent alongside the increasing capabilities of our mobile devices. In Singapore, the rise of mobile malware is considered one of the top threats in the country’s cybersecurity landscape.

Like desktops, most mobile devices today have internet access. This allows threat actors to target them through malicious apps and websites, resulting in data theft, data encryption, surveillance, etc.

Furthermore, these apps come in a range of different types. The most infamous among these smartphone apps are trojans that pose as popular apps only to try to obtain private login credentials illegally.

2. Mobile ransomware

In line with the nationwide rise in ransomware incidents, CSA received 61 reports of mobile-targeted attacks in 2020, a considerable number of which were mobile ransomware. The number represented a sharp surge in ransomware incidents reported to CSA.

The mobile ransomware variant has grown to be particularly damaging due to the increased usage of mobile devices in Singapore. It encrypts personal data and files on your mobile device and then demands a ransom to release the decryption key that can restore access to the encrypted data.

3. Phishing

One of the most common attack vectors, phishing, enables other forms of cyberattacks. Most of them begin with a phishing email containing a malicious link or attachment containing malware. In fact, 70% of incidents reported to SingCERT by members of the public occurred via phishing attacks. On smartphones, phishing attacks can exploit a range of media for delivering malicious links and attachments, which include email, SMS, trojan apps, and even social media platforms.

4. Man-in-the-Middle (MitM) attacks

Man-in-the-Middle (MitM) attacks revolve around attackers intercepting your network to eavesdrop and modify the data being transmitted. While this form of attack is possible on different systems, mobile devices are particularly susceptible to it. Unlike desktops, where web traffic uses encrypted HTTPS for safe communication, mobile devices do not use such encryption for services such as SMS. As a result, these messages can be easily intercepted through malicious mobile applications using unencrypted HTTP and can be used to transfer personal information.

5. Advanced jailbreaking & rooting techniques

Jailbreaking, much like rooting, is a term for gaining root (admin) access to the underlying operating system (OS) of the device. It involves taking advantage of vulnerabilities in your mobile device’s OS to gain admin access to it. This increased permission enables threat actors to access more data and inflict greater damage than others with limited permissions can.

How to protect yourself from mobile threats

As the mobile landscape rapidly expands and diversifies, the scope for newer threats keeps rising too, prompting a need for mobile security solutions. This is especially true as remote working arrangements make these devices a more popular and crucial component of work. An effective mobile threat defence solution needs to be able to detect and respond to a variety of different attacks while providing a positive user experience.
