According to a report from Asia Times, sensitive information of Punjab National Bank's (PNB) customers have been offered for sale on a website for nearly three months. Due to this, at least 10,000 credit card and debit card owners are to be affected. Allegedly, PNB was tipped off by Singapore-based company called, CloudSek Information Security. This comes in as a second blow for PNB following the alleged huge scam led by Nirav Modi.
