The ability to save WhatsApp makes your files vulnerable to hackers

Although apps like WhatsApp have become known for providing encrypted and secure communication, the researchers have found that hackers can use malware to modify files sent through these apps and hack Whatsapp accounts.

In Android, apps can store photos or audio files in internal storage that are only accessible in within the app itself, or they can store files in external storage, in which many other apps will also access to it.

Cause trouble.

One of the WhatsApp spokesperson said that relocating files not only reduces the app’s ability to share files, but also creates new security issues. He also said that WhatsApp is trying to take advantage of the best features available in operating systems and apply updates in this regard.
