From 2005 to 2014, six large enterprises, including TJX Cos, Sony, Target and Home Depot, were attacked by Hackers, according to Wall Street Journal. The most recent cyber-attack targeted on millions of Home Depot customer and put 56 million payment cards in risk, which is significantly larger than the Target breach that occurred three weeks leading up to Christmas last year.
The Home Depot data breach has started to trigger fraudulent transactions. Financial institutions are stepping up efforts to block the fraudulent transactions by rejecting them if they appear unusual. Some large financial institutions, such as J.P. Morgan Chase and Capital One have proactively started reissuing cards to customers whose data were exposed. While banks dealing with cyber-attack, IT companies attempt to provide advanced solution to better secure data. For example, Cisco launched a new firewall security solutions that automatically assess threats, optimize defense to protect the network of the enterprise. Other companies such as VMWare, McAfee, HP also launched or updated their data protection softwares this month.
An increasing number of credit card enrollment in online payment and mobile payment services creates new security challenges to our society. While data volume continue to expand, cyber-attacks appear more often and make more broader impact. Once hacking into the computer systems, hackers can steal millions of users’ private information, including credit card number, name, address, and sometimes social security numbers. This has raised big public concerns.
