Mobile App Security: Top 5 Mobile Security Threats
The explosion of smartphones in the workplace and in everyday situations has made them a prime
target for hackers.
No computing device is 100% secure, and threat actors continue to look for new ways to exploit
vulnerabilities on mobile devices.
According to Nicholas Fearn, in 2017 the number of attacks on mobile applications increased by 63%, so
it is extremely important to be aware of the most serious security threats to mobile devices.
1. Unsecured Wi-Fi
Unverified servers and unsecured Wi-Fi networks in coffee shops or bookstores are a haven for hackers,
not to mention one of the biggest security threats to mobile devices.
According to CNBC reporter Jennifer Schlesinger, hackers are trying to compromise businesses with
mobile vulnerabilities due to the rise of smartphones in the workplace.
Despite warnings from smartphone users about potentially dangerous and unverified servers, users will
continue to connect to dangerous networks.
Threat originators can use these insecure networks to access sensitive data directly from phones or
apps.
2. Applications with malicious code
Smartphone users downloaded 269 billion mobile apps in 2021.
However, users can download apps from third-party websites outside of the Google Play Store or Apple
App Store.

Hackers can use insecure apps to exploit sensitive data from mobile users.
For example, a malicious mobile app called "Gooligan" infected 1.3 million Android users and the threat
actors were able to steal user data.
Hackers can duplicate apps and host them on third-party app stores, and then, like phishing frauds, use
malware to steal data.
You can prevent mobile security threats by only downloading apps from official app stores.
3. Operating system vulnerabilities
Smartphone manufacturers must continually update their operating software to provide technological
improvements, new features, and overall system performance.
The smartphone user is advised to update operating systems periodically (for example, iPhone users on
iOS operating systems).
Software developers monitor emerging vulnerabilities and tune operating systems to address threats.
However, users may choose not to update the system, or their device may no longer be compatible with
the latest update.
The best defense against emerging mobile threats is to update the operating system as soon as possible
and update the mobile device if the operating system is no longer compatible with latest updates.
4. Data leaks
Mobile applications usually store data on remote servers.
Users often download apps and fill out prompts right away to start using the app, but often do not check
it out properly.

Advertisers can mine data to learn more about the target demographic, but cybercriminals can also gain
access to servers and leak sensitive data.
Unintentional data leaks can be caused by caching, insecure storage, and browser cookies.
5. Problems of cryptography
Mobile cryptography is critical to security and keeps data and applications secure.
The iOS software must verify that the app is digitally signed from a trusted source and then decrypt the
app to execute it.
The Android software simply verifies that the app is digitally signed and does not necessarily verify the
trustworthiness of the signer.
This design of digital trust increases the importance of downloading applications from an official source.
Sensitive data at rest on a mobile device typically falls prey to inadvertent disclosure due to poor or
complete lack of cryptographic implementations.
Developers working on tight deadlines or trying to cut corners may use encryption algorithms with
existing vulnerabilities or no encryption at all.
Threat actors can exploit these vulnerabilities or steal data from a compromised mobile device.
