As of 2024, nearly every American owns a cellphone of some kind with 91% owning a smart phone(<\/sup>1)<\/sup>. Of these, roughly 78% use their device for mobile banking and over half use it as a digital wallet, storing all their financial data in one location. <\/p>\n\n\n\n

On top of this, just under half of smart phone users protect their device and its multiple apps and services, including online banking, behind the same PIN(<\/sup>2)<\/sup>. That is if they use a PIN or password on their device at all, which over a quarter of Americans don\u2019t(<\/sup>1)<\/sup>. <\/p>\n\n\n\n

As a result, cybercriminals have focused their efforts toward compromising mobile devices. Unique mobile malware <\/a>samples increased by 13% last year, and 83% of phishing sites<\/a> now target mobile devices(3)<\/sup>. <\/p>\n\n\n\n

Because of this, it\u2019s never been more important to ensure that your mobile device, your activity on it, and the networks you connect to are secure. Many people worry about claims that someone can hack a bank account with just a phone number<\/a>. In reality, these fears usually come from misunderstandings about how mobile security works and how cybercriminals actually gain access to accounts. Read on to learn about proactive safety practices, signs of intrusion, and steps to take if your mobile device has been hacked. <\/p>\n\n\n\n

<\/span>Understanding the Attack Vectors: How Phones Get Hacked <\/span><\/h2>\n\n\n\n

There are numerous ways that a cell phone can be infiltrated. Cybercriminals will exploit any vulnerability available to gain access to your devices and the data stored upon them. Knowing their strategies can help you avoid risky behaviors that may put your device\u2019s security at risk. <\/p>\n\n\n\n

<\/span>Malicious Apps and Software: <\/span><\/h3>\n\n\n\n

Roughly one in every four protected mobile devices experience malware exposure<\/a>(3)<\/sup>. This is due in large part to the practice of sideloading, or downloading programs from unofficial app stores. Devices that have engaged in sideloading are 200% more likely to contain malware(3)<\/sup>. <\/p>\n\n\n\n

Specifically, Android devices have a vulnerability in their OS that allows malicious apps to send permission requests that overlay requests from legitimate apps. This means when an app like Instagram asks for permission to your photos or camera, a malicious program can sneak a request in as well(<\/sup>4<\/sup>)<\/sup>. <\/p>\n\n\n\n

<\/span>Phishing and Social Engineering: <\/span><\/h3>\n\n\n\n

In addition to the rise in phishing sites targeting mobile devices, there was a 28% increase in vishing attacks<\/a> and a 22% increase in smishing attacks in 2024(5)<\/sup>. Together, this has resulted in over half of all personal devices encountering a phishing attack <\/a>each quarter(6)<\/sup>.\u00a0<\/p>\n\n\n\n

These attacks utilize social engineering to pose as a trusted entity, such as a business the target uses. A recent example of this is the fake toll payment text scams that have been circulating in early 2025. These texts take targets to a fake payment website which harvests their log in and financial credentials. <\/p>\n\n\n\n

<\/span>Network Attacks (Man-in-the-Middle and Rogue Wi-Fi): <\/span><\/h3>\n\n\n\n

Your mobile security may be jeopardized by a hacked Wi-Fi router or unsecure public network. Over half of internet users use public Wi-Fi(<\/sup>1)<\/sup>, and roughly 4 in 10 public Wi-Fi users have had their private information compromised, with some instances taking less than 10 minutes from the time of connection for malicious activity to be detected(<\/sup>3)<\/sup>. <\/p>\n\n\n\n

MITM attacks are often carried out by setting up an imposter Wi-Fi network in areas such as airports, cafes, libraries, and other public venues that typically offer free internet. Hackers may even compromise a legitimate public Wi-Fi network by manipulating rogue access points. Regardless, MITM attacks allow cybercriminals to intercept personal data including log in credentials, banking information, and other private communications conducted on your device. <\/p>\n\n\n\n

<\/span>Zero-Day Exploits and Operating System Vulnerabilities: <\/span><\/h3>\n\n\n\n

Zero-Day exploits are vulnerabilities that are manipulated by bad actors before the software distributor recognizes their existence and patches them. They are significant because the developer has \u201czero days\u201d to secure the software since it is already being exploited. <\/p>\n\n\n\n

Because of this, it\u2019s important to install software updates as soon as they become available. However, 75% of smartphone users in the United States say they only update their operating system when it’s convenient with an additional 3% saying the never perform updates(<\/sup>7<\/sup>)<\/sup>. It\u2019s important not to fall into this demographic for the sake of your mobile security. <\/p>\n\n\n\n

<\/span>Physical Access and Device Tampering: <\/span><\/h3>\n\n\n\n

If a hacker can obtain physical access to your device, they may be able to install malicious programs like spyware and remote access trojans (RATs) directly to your device without the need for a backdoor. <\/p>\n\n\n\n

 
Hackers may use rubber ducky devices, which are Human Interface Devices (HID) which appear like USB drives. However, these devices can be used to harvest user data and inject malicious software while going undetected as it appears as a HID device. Because of this, it’s important to never leave your phone or other devices unattended. <\/p>\n\n\n\n
