Is hacking into banks’ websites and transferring money from them regarded as stealing that incurs the punishment of amputation?
Question

                Is hacking into bank websites via the internet and transferring money from them into the hacker’s account considered stealing? Should this hacker receive the punishment for stealing?.
Praise be to Allah.
    Stealing is haraam, and is a major sin. The Prophet  
    (peace and blessings of Allaah be upon him) said: “No thief is a believer at 
    the time when he is stealing.” Narrated by al-Bukhaari (5578) and Muslim 
    (57). 

    Undoubtedly hacking into banks’ websites and transferring 
    money from them is haraam, and consuming people’s wealth unlawfully. 

    As to whether it is something that incurs the punishment of 
    amputation, that is to be determined by the shar’i judge to whom the case is 
    referred. 

    There are conditions which must be met before the thief’s 
    hand is amputated, such as that the property that is stolen should have been 
    taken from a proper storage place (in which wealth is usually kept). 

    Imam al-Qurtubi (may Allaah have mercy on him) said:  

    The majority of scholars are agreed that amputation can only 
    be carried out on one who took from a proper storage place that for which 
    amputation is deserved. 

    A proper storage place is that which is usually set up to 
    store people’s wealth, which varies from one case to another. 

    Ibn al-Mundhir said: There is no definite report or scholarly 
    opinion concerning that, rather it is like consensus among the scholars. End 
    quote. 

    Tafseer al-Qurtubi (6/162). 

    The scholars of the Standing Committee were asked:  

    What are the conditions for amputating the hand in the case 
    of theft? 

    They replied: 

    For the hand of the thief to be cut off, nine conditions must 
    be met: 

    1.Stealing, which is taking 
    wealth or property by stealth. If he seizes it forcibly or snatches it, then 
    there is no amputation.

    2.The thief should be 
    accountable; there is no amputation for a child or one who is insane.

    3.The stolen item should be above 
    a certain threshold; there is no amputation for anything less than that. The 
    threshold is one quarter of a dinar of gold, or the equivalent value of 
    other things.

    4.The stolen item should be 
    something that is customarily kept and stored.

    5.The stolen item should be 
    something concerning which there is no doubt. 

    6.It should be stolen from a 
    proper storage place.

    7.It should be taken out of the 
    storage place.

    8.Proof of the theft should be 
    established before the judge, with two witnesses of good character or a 
    confession from the thief.

    9.The owner of the stolen item 
    should come forward and claim it.

    Examination of these conditions and the decision as to 
    whether they apply to a case of theft, is something that should be referred 
    to the shar’i courts. End quote.
