According to the Federal Investigation Agency (FIA), around 20 Pakistani banks have suffered cyber-attack. On 27th October 2018, BankIslami noticed suspicious transactions of Rs2.6 million through its international payment card scheme. The bank immediately suspended its international transaction by shutting down its international payment scheme. The bank has credited all monies withdrawn from the accounts on 27th October i.e. Rs2.6 million to their respective accounts.
After suspending the internation transactions, the international payment scheme claimed that transactions of around 6 million USD were made on international ATM through Bank’s issued cards, however these transactions were not seen on bank’s system.
Afterwards, some more banks issued security alerts. They either blocked their customers’ credit/debit cards or blocked their online and international use. Customers were forwarded SMS notifications of the changes.
The threat intelligence and anti-fraud firm, Group-IB, reported the security breach of Pakistani banks including Habib Bank, MCB Bank, Allied Bank and many more on November 13, 2018. Prior to this incident, Group-IB detected the compromise of Pakistani bank’s card information uploads.
“Card dumps are usually obtained by using skimming devices and through Trojans infecting workstations connected to POS terminals. The large part of compromised card data is sold in specialized card shops, such as Joker’s Stash”
Head of Group-IB сybercrime research unit
A data dump was posted on the Darkweb with over 9,000 to 12,000 debit cards information, the majority of the customers belonged to the Pakistani banks. Even though BankIslami came in the limelight and initially the media reported the neglect of a single bank but the dump showed a dissimilar story as it contained thousands of debit card information of various other Pakistani banks.
The Darkweb is an encrypted online platform that does not appear on conventional search engines. A particular web browser is required to access the deep web. The Darknet constitutes the dark web. The Darkweb concept is achievable with the help of anonymity tools like; Tor (“The Onion Routing” project) and I2P (invisible internet Project). It is popular for both user protection and black market. In a nutshell, Darkweb is an online market of drugs, human trafficking, exchange of stolen goods (financial and credential) and much more. All transactions on the Darkweb are often made in bitcoins or through purchasing goods in a way that both the buyer and seller are both protected from being tracked.
