Suspected Chinese Hackers Stole Data on Millions of US Federal Workers by VOA News U.S. officials say hackers in China launched a massive cyberattack on the federal agency responsible for collecting background information on, and issuing security clearances for millions of government employees. The Office of Personnel Management (OPM) said Thursday as many as 4 million current and former federal employees may have been affected. It said that number could go higher as the investigation continues. Law enforcement officials say they believe China-based hackers, possibly with links to the Chinese government, were behind the attack, believed to be the most extensive breach of federal employee data in years. A Chinese embassy spokesman in Washington, Zhu Haiquan, said China outlaws cyber warfare, saying "jumping to conclusions and making hypothetical accusations is not responsible and counterproductive." The top Democrat on the House Intelligence Committee, California's Adam Schiff, said this attack is most shocking "because Americans may expect that federal computer networks are maintained with state of the art defenses." OPM says it detected the security breach in April before it took what it calls an "aggressive effort" to implement tougher controls. It says the Federal Bureau of Investigation and Department of Homeland Security are investigating to determine the full extent of the damage. The FBI says it takes all threats to public and private sector cyber systems seriously and will hold those who make such threats accountable. It is not clear if specific government employees were targeted, or if the hackers simply swept up large amounts of employee data for later use. Officials would also not say what type of information was accessed or stolen. As the human resources office of the federal government, OPM is seen as a high-value hacking target. Its computers store sensitive employee information such as social security numbers, payroll data, job performance and family information. OPM said it will notify all current and ex-federal employees whose information may have been compromised. The agency will offer those workers access to credit reports and monitoring, and identity theft recovery services at no cost. The OPM cyberattack may be the biggest, but is not the first time hackers gained access to federal government computer systems. Unclassified computers at the White House and State Department have been hit. Twitter and YouTube accounts of the U.S. central military command were also struck. The Internal Revenue Service, which is responsible for tax collection, said last month that hackers stole information on 100,000 U.S. taxpayers. Cyber warriors have also attacked such commercial giants as the Sony Pictures movie studio, Target and Home Depot stores, the EBay on-line auction site, and JP Morgan Chase bank. Some of the attacks have been blamed on North Korea, Russia and China. Experts say China is desperate to get its hands on U.S. industrial and trade secrets. China angrily denies the accusations and says it has been targeted by U.S. hackers. The U.S. last year charged five Chinese military officers with hacking into and stealing trade secrets from the computers of several large American nuclear, metal and solar companies. China denounced the indictment and suspended a series of discussions with the U.S. to combat cyber crimes. __________________________________________________________________ [1]http://www.voanews.com/content/suspected-chinese-hackers-stole-data- on-millions-of-us-federal-workers/2808586.html References 1. http://www.voanews.com/content/suspected-chinese-hackers-stole-data-on-millions-of-us-federal-workers/2808586.html
