When it comes to securing your organization, don't forget to protect any mobile applications that your company owns and makes money from. It's critical because phishing attacks, data leakage, poor user authorization, and other vulnerabilities would harm your customers, which means these cyberthreats would harm your company's reputation
What is the security of mobile apps ?
The popularity of apps no longer surprises anyone; these services have proliferated in the market: according to statistics, mobile services were downloaded more than 200 billion times in 2018, and this is far from their limit. Other statistics, however, are less encouraging: High-risk vulnerabilities were discovered in nearly 40% of application
What causes vulnerabilities in mobile apps?
Let's just say it's usually due to a faulty approach to mobile security.
Furthermore, a large number of vulnerabilities are formed during the development phase, though they may not become apparent until much later: when their elimination requires significant code rewriting. As a result, it is preferable to protect the app code from the start. This will save you unnecessary work and money in the future.
When a few minor security breaches combine, they can have a synergistic effect, which can have disastrous consequences. Though each of these breaches has a minor impact on mobile app security.
Top mobile application security vulnerabilities
Lack of binary protections
Due to the absence of binary safeguards, a mobile app's source code can be easily decompiled, reverse-engineered, and viewed in clear text without the use of any special tools. Once the app source code has been decompiled, it is simple to search for identifiers like APIs, encryption keys, and tokens
Insecure data storage
Data transmitted via an app may have been insecurely kept, either temporarily or permanently, outside of a "sandbox," in the local file system of the device, in external storage, or copied to the clipboard, making it accessible to other apps or intruders.
Unintended data leakage
Unintentional data leakage occurs when either 1) data is stored on a mobile device in a location that is easily accessible by other apps or users (see the previous section, Insecure data storage), or 2) apps share services with other apps on a device, making the app's data available to all other applications on the user's device.
This kind of vulnerability relates to the mobile application's ability to execute malicious code on the client side of the mobile device. Client-side assaults leave gaps that allow access to different mobile device features. An injection vulnerability would even let attackers change the device's trust settings for the apps, potentially allowing them to bypass security measures like sandboxes.
Using obsolete, ineffective, or highly vulnerable algorithms might lead to weak encryption within an application (such as MD5, RC4, DES, SHA1). Many of these older encryption techniques, which were occasionally chosen for their speed or convenience of use, have been replaced by newer, more secure algorithms like AES, 3DES, and RSA.
Private key disclosure
In the event of a private key exposure vulnerability, offline password cracking for the private key will be available if an attacker has access to this key file.
Implicit trust of all certificates
In cryptography, trusted connections between the client browser or app and the issuing server are made possible by the use of public key certificates, also referred to as digital certificates or identity certificates. A certificate authority verifies certificates from large financial services organisations to make sure they are from trustworthy companies and may be used for business transactions.
Execution of activities as root
An adversary could potentially disable the standard security checks being performed by the operating system or surrounding environment by executing code within an application at the root level (a superuser privilege level that gives the application access to all files, executables, and data on the device).
World Writable/readable files and directories
Any process or user can read from, write to, and access files and directories when they are world-readable/writable.
Fortunately (though that's 3% too many), it was found that just 3% of the apps evaluated have directories or files set up with world-readable and writable permissions. Information was not concealed in these cases. Information in the app was human-readable once it had been broken open, making sensitive data accessible and client data no longer safe.
Exposure of SQL queries and database parameters
In this instance, the "keys" to the underlying database and how the information in the database is accessible are provided via the expose of database parameters and SQL queries. This discloses how the software interacts with confidential information and also raises the possibility of an accidental data leak and its associated repercussions.
Although it may first appear that mobile app security is an additional investment, it actually serves to contribute to future prosperity and guard against potential losses in revenue and goodwill.
Experts take extremely seriously their responsibility to protect against mobile viruses and other vulnerabilities. The apps we create are secured at a high level!
