Rankiteo Explanation :
Attack with significant impact with customers data leaks

Description: The cyber attack on the real-time payments platform of Westpac's exposed private details of almost 100,000 Australian bank customers. The attack on Westpac has prompted a warning from computer security experts who say that the pilfered data could be used for fraud. Experts say that with access to these details, fraud could be committed on a mass scale. The bank confirmed the incident late on Monday but did not say how many Australians had been affected."
