Your medical information is worth 10 times more than your credit card number on the black market.
Last month, the FBI told healthcare providers to guard against cyberattacks after one of the largest US hospital operators, Community Health Systems Inc, said suspected Chinese hackers had broken into its computer network and stolen the personal information of 4.5 million patients.
Security experts say cybercriminals are increasingly targeting the US$3 trillion US healthcare industry, which has many companies still reliant on aging computer systems that do not use the latest security features.
“As attackers discover new methods to make money, the healthcare industry is becoming a much riper target because of the ability to sell large batches of personal data for profit,” said Dave Kennedy, an expert on healthcare security and CEO of TrustedSEC LLC. “Hospitals have low security, so it’s relatively easy for these hackers to get a large amount of personal data for medical fraud.”
Interviews with nearly a dozen healthcare executives, cybersecurity investigators and fraud experts provide a detailed account of the underground market for stolen patient data.
The data for sale includes names, birth dates, policy numbers, diagnosis codes and billing information. Fraudsters use this data to create fake IDs to buy medical equipment or drugs that can be resold, or they combine a patient number with a false provider number and file made-up claims with insurers, according to experts who have investigated cyberattacks on healthcare organizations.
Medical identity theft is often not immediately identified by a patient or their provider, giving criminals years to milk such credentials. That makes medical data more valuable than credit cards, which tend to be quickly canceled by banks once fraud is detected.
Stolen health credentials can go for US$10 each, about 10 or 20 times the value of a US credit card number, according to Don Jackson, director of threat intelligence at PhishLabs, a cybercrime protection company. He obtained the data by monitoring underground exchanges where hackers sell the information.
The percentage of healthcare organizations that reported a criminal cyberattack had risen to 40 percent last year from 20 percent in 2009, according to an annual survey by the Ponemon Institute think tank on data protection policy.
Fueling that increase is a shift to electronic medical records by a majority of US healthcare providers.
Healthcare providers and insurers must publicly disclose data breaches affecting more than 500 people, but there are no laws requiring criminal prosecution. As a result, the total cost of cyberattacks on the healthcare system is difficult to pin down. Insurance industry experts say they are one of many expenses ultimately passed onto US citizens as part of rising health insurance premiums.
Consumers sometimes discover their credentials have been stolen only after fraudsters use their personal medical ID to impersonate them and obtain health services. When the unpaid bills are sent on to debt collectors, they track down the fraud victims and seek payment.
The US government’s efforts to combat Medicare fraud have focused on traditional types of scams that involve provider billing and over billing. Fraud involving the Medicare program for seniors and the disabled totaled more than US$6 billion in the past two years, according to a database maintained by Medical Identity Fraud Alliance.
“Healthcare providers and hospitals are just some of the easiest networks to break into,” said Jeff Horne, vice president at cybersecurity firm Accuvant, which is majority-owned by private equity firm Blackstone Group.
KPMG partner Michael Ebert said security has been an afterthought for many medical providers — whether it is building encryption into software used to create electronic patient records or in setting budgets.
“Are you going to put money into a brand new MRI machine or laser surgery or are you going to put money into a new firewall?” he said.
A fire caused by a burst gas pipe yesterday spread to several homes and sent a fireball soaring into the sky outside Malaysia’s largest city, injuring more than 100 people. The towering inferno near a gas station in Putra Heights outside Kuala Lumpur was visible for kilometers and lasted for several hours. It happened during a public holiday as Muslims, who are the majority in Malaysia, celebrate the second day of Eid al-Fitr. National oil company Petronas said the fire started at one of its gas pipelines at 8:10am and the affected pipeline was later isolated. Disaster management officials said shutting the
US Vice President J.D. Vance on Friday accused Denmark of not having done enough to protect Greenland, when he visited the strategically placed and resource-rich Danish territory coveted by US President Donald Trump. Vance made his comment during a trip to the Pituffik Space Base in northwestern Greenland, a visit viewed by Copenhagen and Nuuk as a provocation. “Our message to Denmark is very simple: You have not done a good job by the people of Greenland,” Vance told a news conference. “You have under-invested in the people of Greenland, and you have under-invested in the security architecture of this
Japan unveiled a plan on Thursday to evacuate around 120,000 residents and tourists from its southern islets near Taiwan within six days in the event of an “emergency”. The plan was put together as “the security situation surrounding our nation grows severe” and with an “emergency” in mind, the government’s crisis management office said. Exactly what that emergency might be was left unspecified in the plan but it envisages the evacuation of around 120,000 people in five Japanese islets close to Taiwan. China claims Taiwan as part of its territory and has stepped up military pressure in recent years, including
UNREST: The authorities in Turkey arrested 13 Turkish journalists in five days, deported a BBC correspondent and on Thursday arrested a reporter from Sweden Waving flags and chanting slogans, many hundreds of thousands of anti-government demonstrators on Saturday rallied in Istanbul, Turkey, in defence of democracy after the arrest of Istanbul Mayor Ekrem Imamoglu which sparked Turkey’s worst street unrest in more than a decade. Under a cloudless blue sky, vast crowds gathered in Maltepe on the Asian side of Turkey’s biggest city on the eve of the Eid al-Fitr celebration which started yesterday, marking the end of Ramadan. Ozgur Ozel, chairman of the main opposition Republican People’s Party (CHP), which organized the rally, said there were 2.2 million people in the crowd, but
