One method of hacking they do commonly used these days is "phishing" .
Now phishing is a kind of hacking whereby the replicate already made apps that are popularly used, and sometimes unpopular apps are also used too, they also use emails too the try to get useful info from by replicating emails of people close to you.
So when users try use this phished app the hacker gets hold of all the necessary information the need when the user inputs those information.
I've only falled for this kind of method once, when a friend of mine enlightened me on the situation.
Phishing hacks can come through so many ways, like email scams, duplicating applications softwares.e.t.c.
One of the many ways to prevent this is by insttalling anti-viruses and anti-malware soft ware because it helps as a counter force on phishing attacks.
nd also check every email carefully because when doing phishing attempts it's always easier for a hacker to make mistakes.
I almost fall victim to phishing attack some time ago when i wanted to register on an app i was introduced to, what made me not to fall was when they requested for my Facebook login details or my email login details, i was like why an app of its own would require login details of another app. They even send mails with phishing links but what i have done is that some of the apps that i used my email address to register, i set up an anti-phishing code such that when i receive a mail it must include the anti-phishing code before i will take the mail seriously especially if it is a mail that comes from the centralized exchange i normally use.
that's quite smart of you , trust me I wish I knew very well about phishing a long time ago but after my first incident, I got fully clarified by a friend and since then I now feel like I know all their methods they use.
How I fell into the trap was my Facebook account, back in the days where Facebook lite wasn't a thing yet, the old version of Facebook.
I tried downloading a Facebook app on my little android phone back then , I already had a good account I normally used , I usually log in through websites so one day I decided to download the app not knowing I was downloading a replica of Facebook and not the actual Facebook, when I input all my details It didn't go further again, I tried and tried but to no avail.
I then went back to the website to login and I discovered that my account was no longer under my control.
