Learn Turkish: Dün bir siber korsan banka hesabımı ele geçirdi. - Yesterday, a cyber hacker took over my bank account.

This is the past tense of the idiom ele geçirmek, which literally means 'to cause to pass into the hand.' It is made of el (hand) + -e (dative case: to) + geçirmek (causative of geçmek: to make pass). In Turkish, this is the standard way to say 'to seize', 'to capture', or 'to take control of'.

Why does hesabımı end with -mı, and why did the 'p' in 'hesap' change to 'b'?

The root word is hesap (account). When followed by a vowel suffix, consonant mutation changes the p to b. The phrase starts as a noun compound for 'bank account' (banka hesabı). When you add the first-person possessive to mean 'my bank account', it overrides the compound's own suffix to become banka hesabım. Finally, because the account is the specific direct object being taken over, we add the accusative case suffix (-ı), giving us banka hesabımı.

I learned that korsan means 'pirate'. Is it commonly used for hackers?

Yes! While korsan historically means 'pirate' (like a pirate on a ship), in modern Turkish it is the standard word used for 'hacker' (siber korsan or bilgisayar korsanı). It is also commonly used as an adjective to mean 'bootlegged' or 'unlicensed', such as in korsan taksi (unlicensed cab) or korsan yazılım (pirated software).
