From Wikipedia, the free encyclopedia
Linux is a family of open source Unix-like operating systems based on the Linux kernel, an operating system kernel first released on September 17, 1991 by Linus Torvalds. Linux is typically packaged in a Linux distribution (or distro for short).
Distributions include the Linux kernel and supporting system software and libraries, many of which are provided by the GNU Project. Many Linux distributions use the word "Linux" in their name, but the Free Software Foundation uses the name GNU/Linux to emphasize the importance of GNU software, causing some controversy.

The issue is that the banking app is often the only way to get 2 factor authentication. The other way is to use SMS but that can be hijacked by social engineering attacks so it cannot be considered secure.
Can you please share an example? I'd be curious how that would work, especially if it works while understanding how it works.
It's nothing sophisticated. You just steal someone's phone number by calling their phone service provider pretending to be them. I don't know how serious this threat is but for this reason SMS is not considered secure in the "security circles".
