Turmoil at the VA: New allegations against agency

The U.S. government agency that handles whistleblower claims wrote a letter to President Barack Obama on Monday detailing apparent contradictions within the Department of Veterans Affairs' own investigation of alleged misconduct, CNBC has learned

The VA, the second-largest federal government agency, is being investigated by several government watchdog agencies, including the Federal Bureau of Investigation.

Investigations Inc.: Cyber Espionage

  • When a person enters information on a website, like an email or credit card, it gets stored in that company’s data base. Those web-based forms are a simple tool for users, but they are also another way hackers can exploit a company’s system. Instead of inputting a name into the website, cyber spies can put in a specially crafted text that may cause the database to execute the code instead of simply storing it, Alperovitch said. The result is a “malicious takeover of the system,” he said.

    By attacking business computer networks, hackers are accessing company secrets and confidential strategies and creating huge losses for the overall economy.
