Hacking of Amazon third-party sellers’ accounts

April 16th, 2017

Hackers use passwords for high-profile breaches to compromise Amazon third-party sellers’ accounts. The attackers stole tens of thousands of dollars from sellers’ accounts. They also posted nonexistent items for sale in order to get more funds.

The incident has affected two million seller accounts on Amazon.com account which counts for more than half of its sales. As per the reports, over 100,000 sellers earn more than $100,000 a year.

Amazon seller Margina Dennis told NBC News about the fraud. She got 100 emails from customers. They were complaining of not getting a Nintendo Switch. The product was uploaded on site through her account by hacker. They also changed the accounts password.

An Amazon spokesman said “There have always been bad actors in the world; however, as fraudsters get smarter so do we. Amazon is constantly innovating on behalf of customers and sellers to ensure their information is secure and that they can buy and sell with confidence on Amazon.com.”

Third-Party Risk

CyberGRX CEO Fred Kneip mentioned that hackers are targeting Amazon’s third-party ecosystem for financial gain.

“Amazon is a high-profile example of how increasingly connected businesses have become, but organizations across the world in every industry are undergoing a similar transformation as outsourcing, globalization and the digitization of business expand their digital ecosystems exponentially,” he said.

“Whether it’s one of the world’s largest retailers or a small business, companies need to approach third-party cyber risk as a real threat to their business that needs to be continuously managed,” Kneip added.

AlienVault security advocate Javvad Malik mentioned that third party vendors should look for their own security.

“It is therefore, important that all companies of all sizes have at least a basic level of threat detection controls in place that can alert when unexpected changes occur, or when systems start behaving in an unusual manner,” he said.

“Compromised credentials are the leading attack vectors in cyber breaches, as hackers target networks through trusted third-party suppliers and contractors who likely have less rigorous security than the ultimate target,” Centrify senior director of products and marketing Corey Williams said.

“This certainly won’t be the last time we see third parties being hacked — organizations need to up the security stakes with multi-factor authentication, which requires more than one method of authentication to verify the user’s identity for a login or other transaction, in order to stop the use of stolen credentials,” Williams added.

High value targets for hackers

April 13th, 2017

IT administrators and other high-value targets are valuable to hackers. Enterprise password management solution, Secret Server, Thycotic has created a solution which uses machine learning technology to help companies spot probably compromised accounts along with insider threats.

Privileged Behavior Analytics (PBA), a cloud-based tool in Secret Server 10.2 can detect anomalous behavior in privileged accounts.  R.J. Gazarek, product marketing manager at Thycotic said that the privileged accounts need to be secured as they handle crucial information.

“If privileged access is not monitored, analyzed, and alerted on it can lead to devastating data breaches and abuse from the inside out,” Gazarek told eSecurity Planet. “In some cases, the breach may not even be intentional, just someone accessing a system they shouldn’t have had access to.  Having a tool in place that can detect anomalous and unusual privileged behavior, as it happens, is critical in detecting, stopping, and remediating potential breaches and mistakes.”

Artificial intelligence and threat scoring technologies are used by the Thycotic solution.

“The privileged account behaviors and analytics that PBA extension for Secret Server can detect are, for example, privileged accounts being used outside of normal hours than previously used before, privileged accounts being accessed by employees who have never accessed them previously or privileged accounts which are being used excessively that is deemed abnormal behavior,” explained Joseph Carson, chief security scientist at Thycotic. The tool can also be used to help organizations rein in their use of privileged accounts.

“Being able to see privileged account behavior or deviations from normal usage is a huge advantage from a company who wants to add better security controls or to reduce the amount of unused privileged accounts – in turn reducing the privileged account landscape that could be exploited by cyber criminals,” Carson added.

With the help of Thycotic’s Privileged Behavior Analytics, one can manually set the system’s sensitivity. Email alerting option is also provided.

Ransomeware attack at ABCD

April 8th, 2017

ABCD Pediatrics recently suffered ransomware attack. According to the statement, a virus was inserted to gain access to the healthcare organization’s servers. Patient data was encrypted in the process. Facility contacted IT personnel to take all servers offline. It is conducting detailed analysis.

Experts came to conclusion that this particular type of virus has likely not removed the information from the server.  Facility also mentioned that user accounts may have been accessed through it’s network. Affected information includes names, addresses, phone numbers, dates of birth, Social Security numbers, insurance billing information, medical records, and lab reports.

As per the OCR data breach reporting tool, approximately 55,447 patients may have been affected. ABCD has successfully removed the virus from the system. Corrupted data was also removed from its servers. Secure backup of the facility is not affected and thus used to restore all impacted data. It also mentioned that no PHI was lost or destroyed in the incident.

“Also, please note that ABCD never received any ransom demands or other communications from unknown persons,” ABCD stated. “However, ABCD remains concerned because it discovered user logs indicating that computer programs or persons may have been on the server for a limited period of time.”

Facility has upgraded it cyber security monitoring program to stop future incidents. Call centre is setup for the affected patients.

“Patients also can place a fraud alert on their credit files with the three major credit reporting agencies. A fraud alert is a consumer statement added to one’s credit report. The fraud alert signals creditors to take additional steps to verify one’s identity prior to granting credit. This service can make it more difficult for someone to get credit in one’s name, though it may also delay one’s ability to obtain credit while the agency verifies identity.”

Data breach trends in 2016

April 5th, 2017

As per the IBM report, data breach increased 566 percent in 2016 from 600 million to more than 4 billion. The report also mentioned that healthcare in no longer the most attacked sector. Most of the attack was carried out on financial services industry.

In 2016, 12 million records were affected in healthcare. In previous year, the breach was 100 million records which counts to eighty eight percent drop. IBM surveyed 8000 security clients in 100 countries.

IBM Security Vice President of Threat Intelligence Caleb Barlow mentioned that the cyber attacks was carried out with innovative techniques.

“While the volume of records compromised last year reached historic highs, we see this shift to unstructured data as a seminal moment,” Barlow said in a statement. “The value of structured data to cyber-criminals is beginning to wane as the supply outstrips the demand. Unstructured data is big-game hunting for hackers and we expect to see them monetize it this year in new ways.”

IBM mentioned that for ransomware attacks, 70 percent of the companies paid more that $10,000 to regain the access to data. According to the FBI, cyber-criminals were paid $209 million in first three months of 2016.

Ransomware attacks are on the rise with 400 percent increase. In the coming time healthcare will do many reforms which includes increase in internet of things (IoT) technology. This will increase the attacks.

“Retail and financial services have battened down their hatches,” IDC Health Insights Research President Lynne Dunbrack told HealthITSecurity.com in a 2016 interview. “Now the cyber criminals might still be nipping at those heels, but they are looking at other targets, healthcare being one of them.”

CynergisTek Vice President Dan Berger mentioned that attacks against healthcare are carried out with sophistication.

“The dramatic increase in hacking attacks in 2016, coupled with the large number of patient records compromised in those incidents, points to a pressing need for providers to take a much more proactive and comprehensive approach to protecting their information assets in 2017 and beyond,” Berger stated.

Data breach due to computer virus

March 29th, 2017

Lane Community College (LCC) health clinic recently announced data breach when one of its technician  found a computer virus in the system. The incident has affected PHI of some patients.

As per the reports, virus was transmitting the names, addresses, phone numbers, diagnoses, and Social Security numbers to unidentified third party almost for a year. Facility has notified potentially impacted patients.

“We have no evidence that any of the information was transmitted (from LCC), but there’s the possibility,” LCC Vice President of College Services Brian Kelly said in a statement to the Register-Guard.

Facility conducted internal investigation. It checked 20 other computers at the health clinic. It concluded that only computer was infected with virus. The incident has affected 2,500 individuals.

LCC has advised patients to monitor their bank accounts. Suspicious activity or any threat should be reported to the police. The college health clinic also asked patients to report data breach to their banks, credit bureaus, and credit card companies.

July 2016 HIPPA Journal mentioned that, “Cyberattacks on healthcare organizations are now a fact of life.”

OCR breach portal do not include all the data breaches that are happening around. But the current breach reports gives us the idea of pattern –

48 data breaches were reported as unauthorized access

43 data breaches were attributed to hacking or network server incidents

37 breaches were caused by the loss or theft of devices used to store ePHI or the loss/theft of physical records

4 breaches were due to the improper disposal of records

Stolen records or exposed data includes pattern as below:

60% were due to hacking (2,703,961 records)

78% were due to loss/theft (1,342,125 records)

6% were the result of unauthorized access or disclosure (342,748 records)

63% were the result of improper disposal (118,594 records)

CIA hacking docs on WikiLeaks

March 15th, 2017

WikiLeaks published the 1st part of documents which it claims are retrieved from U.S. Central Intelligence Agency. The initial upload consists of  8,761 documents and files.

“Recently, the CIA lost control of the majority of its hacking arsenal, including malware, viruses, Trojans, weaponized “zero-day” exploits, malware remote control systems and associated documentation,” the organization stated in a press release. “This extraordinary collection, which amounts to more than several hundred million lines of code, gives its possessor the entire hacking capacity of the CIA.”

The source of the document is not clear. WikiLeaks mentioned that the documents were already in circulation among the group of hackers.

“The source wishes to initiate a public debate about the security, creation, use, proliferation and democratic control of cyberweapons,” WikiLeaks stated.

The ways of surveillance includes:

  • Accessing Samsung smart TVs even when the units are turned off
  • Installing software in vehicle control systems in cars and trucks
  • Use of smartphones to access the camera, microphone, user location, audio and texts
  • Efforts are done to bypass encryption of WhatsApp

CIA spokesman Jonathan said “We do not comment on the authenticity or content of purported intelligence documents.”

Skyport Systems EVP Rick Hanson told “Donald Trump previously praised WikiLeaks during his campaign,” he said. “When an organization like WikiLeaks is lauded in any forum there is reason to be concerned.”

“We are losing the cybersecurity war to other nation states and [are] at a deficit in our ability to protect ourselves,” Carbon Black nation security strategist Eric O’Neill said by email. “Now with the release of one of our offensive playbooks, our ability to attack is compromised. All of these tools will now proliferate among those for whom breaching security is a business or profession, leading to additional attacks.”

Contrast Security CTO Jeff Williams mentioned that answer isn’t to focus on “cyber arms control,” which he said will never work. “We need a massive increased focus on writing secure code and defending against attacks,” he said.

“As a nation, we are simply incapable of reliably writing code that isn’t susceptible to these attacks,” Williams continued. “But it’s not impossible. It’s not even that difficult. But we have to change the incentives in the software market, which currently don’t encourage writing secure code.”

Access Now senior legislative manager Nathan White said “Today, our digital security has been compromised because the CIA has been stockpiling vulnerabilities rather than working with companies to patch them,” he said. “The United States is supposed to have a process that helps secure our digital devices and services — the ‘Vulnerabilities Equities Process.'”

“Many of these vulnerabilities could have been responsibly disclosed and patched,” White added. “This leak proves the inherent digital risk of stockpiling vulnerabilities rather than patching them.”

Health Facility suffers data breach due to improper shredding of paper documents

March 9th, 2017

Minnesota-based Allina Health recently suffered data breach due to paper documents, which were emptied into the trash insecurely. As per the reports, proper shredding of the documents was not done.

Documents belong to physician’s private office and was supposed to be shredded at the Minneapolis Heart Institute at Abbott Northwestern Hospital. After the incident, facility launched an investigation. Affected information included patient information including names, medical record numbers, addresses, and insurance information.

As per the OCR data breach reporting tool, incident affected 776 patients.  Facility mentioned that some patients use their Social Security numbers as identification numbers on insurance documents.  Hence there is possibility of Social Security numbers being exposed.

“Allina Health has undertaken a system wide awareness campaign to inform the workforce of the simplified “shred all paper” disposal process and reinforced its safeguards policy to re-emphasize the importance of proper disposal.”

Allina Health also added that there is no information or evidence of any misuse of the data. It is notifying affected patients. Also, one year of free credit monitoring and identity protection services are provided.

“Allina Health has simplified its systemwide process to require all paper and documents be placed into secured or locked shredding bins, whether or not the paper contains patient information,” the statement explained. “All paper is shredded and then recycled. The enhanced process also removes all desk-side recycling bins to prevent paper from being placed into recycling without being shredded first.”

Allina Health mentioned that it takes the confidentiality of patients’ information very seriously. Also, it will take steps to ensure that a similar incident does not occur in the future. Patients who believe they may have been impacted or patients who have other questions should call toll-free number.

Unauthorized employee access at Vanderbilt University

March 6th, 2017

Vanderbilt University Medical Center (VUMC) recently suffered data breach when it came to know about the unauthorized employee access to patient medical records. As per the reports, concerned employee were working as patient transporters. Patients’ electronic medical records was accessed without necessary permissions.

As per the statement, “The breach prompted the medical center to change the way the patient transport staff gets information so that it no longer gives them access to electronic medical records. Staff in that department were also retrained about appropriate access to information. VUMC is in the process of migrating from its current electronic health record system to a new software system designed by Epic Systems.”

Facilty conducted an audit of electronic medical records (EHR) which was accessed by the employee.  As per the reports, two employees were involved in the breach who viewed adult and pediatric patient information, including patients’ names, dates of birth, and medical record numbers for internal use. One of them got access to patient Social Security numbers in a few instances.

VUMC mentioned that there is no information whether data was downloaded, transferred, or misused in any way. Affected patients received notification letter Facility has offered fraud or identity theft services. As per the report from The Tennessean, incident affected 3,247 medical records.

“We are committed to providing our patients the highest quality care and protecting the confidentiality of their personal information. To our knowledge, the information the employees viewed was not printed, forwarded or downloaded.  So far, we have no reason to believe that our patients’ personal information has been used or disclosed in other ways,” said VUMC Chief Communications Officer John Howser. “While we are not aware of any risk of financial harm to these patients, we are contacting each of them by letter to recommend that they vigilantly review account statements and their credit status.”

Data breach due to hacking

March 2nd, 2017

Emory Healthcare’s Orthopaedics & Spine Center and Brain Health Center (EHC) at Emory Clinic recently suffered data breach, which impacted almost 80,000 patients. Facility came to know about the incident on Jan 3, 2017. It involved third party database called Waits & Delays. As per the statement, the affected database was used for patients’ appointment information.

Affected information included patient names, dates of birth, contact information, internal medication record numbers, dates of service, and physician names. The above information was removed from the server by an unauthorized individual. The person demanded payment from EHC to restore the data.

As per the reports, individuals who scheduled an appointment at the Orthopaedics & Spine Center within Emory Clinic between March 25, 2015 and January 3, 2017, and any patients with an appointment at Emory Clinic Brain Health Center between December 6, 2016 and January 3, 2016 are potentially affected.

As per the OCR data breach reporting tool, incident affected 79,930 individuals.  Facility mentioned that no Social Security numbers, financial information, diagnoses, or any other information from patient EHRs were accessed during the incident.

Another instance of unauthorized access by an independent security research center was also noticed. It resulted due to efforts of finding gaps in application security to alert companies of areas needing improvement by security company.

Facility launched an internal investigation after the incident. It also notified law enforcement. Potentially affected individuals are also notified. EHC is performing analysis on its current security measures. Internal and external systems which contained patient information will be changed as per the reports.

EHC mentioned that it has no information or indication of accessed data misuse.

“Please refer to the notice you will receive in the mail regarding steps that you can take to protect yourself. In general, we recommend, as a precautionary measure, that you remain vigilant to protect against potential fraud and/or identity theft by, among other things, reviewing your account statements and monitoring credit reports closely. If you detect any suspicious activity on an account, you should promptly notify the financial institution or company with which the account is maintained. You should also promptly report any fraudulent activity or any suspected incidents of identity theft to proper law enforcement authorities, including the police and your state’s attorney general.”

Financial companies get new security law

February 28th, 2017

The State of New York will be implementing new regulations that require banks, financial services companies to have cyber security programs and also maintain them to specific standards.

“As our global financial network becomes even more interconnected and entities around the world increasingly suffer information breaches, New York is leading the charge to combat the ever-increasing risk of cyber attacks,” Maria T. Vullo, superintendent of the New York State Department of Financial Services, said in a statement.

Financial companies now need to check security at third party vendors. Also, they need to maintain adequately funded and staffed cyber security program. It should be monitored by qualified management. The team should report to organisation’s senior body.

Standards are also set for access controls, encryption and penetration testings. Breaches should have response plan. Preservation of data comes under this new rule. And notification to the Department of Financial Services should be sent.

Prevalent director of product management Jeff Hill told “The economic wake of a substantial data breach can stretch for years, impacting not only tangible bottom line results, but also inflicting reputational damage that can linger indefinitely.”

“New York State’s new rules are particularly forward-looking in that they emphasize the importance of understanding and managing third party risk, the source of more than half of all breaches according to a number of studies,” Hill added. “Addressing what is often the soft underbelly of many enterprises’ cyber security defenses — third parties/vendors — the State of New York is forcing a critical element of its economic infrastructure to cover all its bases.”

“In recent times, the regulatory pendulum has begun to swing in favor of a ‘lighter’ approach for banks, financial services and for other industries too, for that matter,” VASCO Data Security head of global marketing David Vergara said by email. “It’s good to see, however, that good sense regulations like this one have survived to offer additional consumer protection via thorough evaluations of third party vendors, comprehensive risk assessments and advocacy for stronger multi-factor authentication.”
