Target Corp New York was attacked and hacked by hackers compromising ' up to 40 million credit and debit cards also managed to steal the encrypted personal identification number ( PIN). Molly Snyder, Target spokesperson said " no unencrypted PIN data is accessed " and there was no evidence that PIN data is "committed " . She confirmed that some " encrypted data " has been stolen , but declined to say if that included any encrypted PINs .
A major U.S. bank afraid that thieves can decrypt the encryption code and make fraudulent withdrawals from bank accounts of consumers, said the executive, who reacted on condition of anonymity because the violation of the data is still under investigation.
Officials say it is too early to reach a conclusion by now as forensic and criminal investigations are still ongoing and there is no reason to believe that PIN data has been compromised or not. And that you have not been informed of any problems in communicating with financial institutions to date.
The No. 3 U.S. retailer said last week that hackers stole data of up to 40 million cards used at Target stores during the first 3 weeks of the holiday shopping season , which made it the second largest violation of the data in the history of U.S. retail . The attack could end up costing hundreds of millions of dollars, but so far it is not clear that who will bear the costs. While bank customers are not liable for losses due to fraudulent activity on their credit cards and debit cards , Banco Santander and JPMorgan Chase & Co said it has decreased the limits on the amount of cash customers can take cashiers and spend in the shops.
JPMorgan said it was able to reduce discomfort by offering customers new debit cards printed quickly in many of its branches, and maintaining bank branches open for extended hours .
Security experts said it is very rare that banks reduce limits on withdrawals , and the decision probably reflects concerns that the PIN have fallen into criminal hands , even if encrypted . Although the use of encryption codes can prevent hackers fans get digital keys to customer bank deposits , the main concern is that the encoding can not stop the kind of sophisticated cyber- criminal who was able to infiltrate Target three weeks .
Daniel Clemens, director general packet Ninjas, a consulting firm cybersecurity , said banks were prudent to lower debit card limits , since no one knows for sure if the PIN encryption Target was infallible until the investigation is complete.
Examples of security vulnerabilities PIN encryption , Clemens had once worked for a retailer that hired his company to hack into your network to find security vulnerabilities. He was able to access the "key" secure digital uses to decrypt the encrypted PIN , which astonished said his client, who thought that the data is secure .
In other cases , hackers can get the PIN by using a tool known as a " scraper RAM" , which captures the PIN numbers, while temporarily stored in memory, as Clemens said.
The Target attack began on 27 November, the day before the holiday giving thanks , and continued until December 15. Banks that issue credit and debit cards learned about the rape of 18 December , and Target publicly the loss of data from your personal account on December 19.
On 21 December , JPMorgan , the largest U.S. bank , Alerted 2,000,000 holders of debit cards was down the daily limit ATM withdrawals and $ 100 and capping store purchases with their cards at $ 500.
On Monday , the bank partly eased the limits imposed on Saturday , putting them at $ 250 per day for ATM withdrawals and $ 1,000 a day for shopping. ( The daily limits usual debit card is $ 200 to $ 500 for cash withdrawals and $ 500 for the purchase, a bank spokesperson said last week. )
On Monday , Santander - a unit of Banco Santander of Spain - lowered the daily limits for cash withdrawals and purchases from Santander and Sovereign brand debit and credit cards of customers who use them at Target when the violation occurred . Santander , however , did not mention the new limits , but said that oversee the accounts and issued new cards to customers who were affected .
The biggest failure against a U.S. retailer Discovered in TJX Cos Inc , in 2007 led to the theft of data from more than 90 million credit cards for about 18 months.
This shows in this era of technology , nothing is safe from hackers. Since this technology is proving to be a boon for some, but is showing its negative effects , you definitely have to be resolved.
