Last year, Cosmos Bank in Pune was attacked by cybercriminals. Hackers broke into the ATM server of the bank and stole the details of Visa and Rupay debit card owners. This attack resulted in a loss of Rs 94 crore for the bank as well as a major privacy breach for the users. Hackers are not always as cool as V from V for Vendetta with his Guy Fawkes mask and cool daggers, single-handedly destroying fascism. Attacks like the one at Cosmos Bank are a threat not just to businesses but also to folks who use those businesses.
How was it possible for hackers to pull off something as huge as the theft of INR 94 crores without even being physically present? Can it be stopped? Where does ethical hacking come into play? Let’s learn about this a little more.
What is hacking?
When we read the word hacking, we may instantly think of a black screen running endless lines of bright green code like Matrix, but really, what is hacking? To put it simply, hacking is using computer skills to find the weaknesses in a computer or a network and then, exploiting those weaknesses by gaining unauthorized access to the system or network.
Think of a computer or a network as a room. A hacker would survey the room from the outside, identify all the weaknesses in that room such as breakable windows, weak locks, etc., and find out ways to break into that room without raising any alarms.
