DNC Email Hack Highlights Need for Proactive Email Security

A Proactive Approach Could Have Prevented the DNC Email Hack

The NSA isn’t the only Washington organization being embarrassed by a data breach. The sorry state of cyber security in America has taken center stage in this year’s presidential election. In June, it was discovered that Russian cyber criminals had managed to hack the Democratic National Committee’s email server, stealing over 20,000 emails and sharing them with WikiLeaks. While most of the emails contain mundane correspondence, some of them are quite embarrassing and imply possible ethical violations on the part of DNC insiders, such as emails questioning Bernie Sanders’ religion and implying the party officers wished to derail his campaign. Shortly after the emails were released, the DNC’s chairperson, CEO, and communications director abruptly resigned. Even worse, the New York Times has revealed that the DNC email hack might be much more extensive than originally believed, involving the email accounts of over 100 individuals and groups.

DNC Email Hack Highlights Need for Proactive Email Security

The DNC email hack bears a strong resemblance to the equally scandalous email hack perpetrated on Sony Pictures two years ago, which was believed to have been carried out by North Korean nation-state hackers. That hack involved the release of 170,000 emails, many of them containing negative commentary about major Hollywood stars. Sony’s chairperson was removed, the company ended up being sued, and the emails are still live on WikiLeaks, neatly indexed and searchable.

While the Sony hack and the DNC email hack involved ethical and privacy violations, the release of corporate emails can damage an organization even if the employees in question did nothing wrong. Confidential information about new product launches, marketing strategies, and partnership negotiations are routinely discussed via email, and this information could destroy a company if it fell into the hands of a competitor.

Proactive Ways to Prevent Email Hacks

Both the Sony hack and the DNC email hack could have been prevented using proactive email security measures. Following are three things your company can do to prevent your emails from ending up on WikiLeaks – or in the hands of a competitor.

Train Your Employees How to Spot Spear Phishing

It is believed that the Sony hack and the DNC email hack happened after hackers used a spear-phishing campaign to get hold of legitimate login credentials. Spear phishing has become extremely popular among hackers as end users have become more aware of these scams and as spam filters have gotten better at recognizing and intercepting regular phishing emails. Because spear-phishing emails are sent to only a small group of targets and are carefully researched and crafted to appear legitimate, they tend to pass through spam filters. Therefore, the best defense is employee awareness. See our previous blog for more information on how to spot spear phishing emails.

Set Up Your System to Assign Employee Passwords

Regardless of how many times they are told not to do so, employees frequently choose passwords that are weak, and they tend to use the same password to access multiple systems, including their personal and work accounts. Thus, a hacker may be able to use an employee’s Dropbox password to get into their work email. For this reason, random, strong passwords should be assigned to employees, and the system should be set up to require periodic password changes.

Outsource Your Enterprise Email

In most cases, using a private email server for company email, as the DNC did, is a bad idea. The majority of companies do not have the in-house technical expertise to securely set up an email server, continuously monitor it for unusual user behavior, or maintain up-to-date spam filters. Large enterprise email providers such as Google and Yahoo do. While using one of these providers is not a guarantee that you will not be breached – especially in light of the popularity of social engineering – a third-party provider will offer a higher level of email security than you could achieve in-house.

HIPAA Compliance Alone Does Not Equal Data Security

Healthcare is one of the most regulated industries in the U.S. HIPAA, or the Health Insurance Portability and Accountability Act of 1996, requires healthcare organizations and their third-party service providers, such as labs and billing companies, to have data security measures in place protect patients’ private health information (PHI). HIPAA compliance is complex, and the penalties for non-compliance are stiff; if a facility’s PHI is breached, and it is found they were not compliant with HIPAA, the facility could face millions of dollars worth of fines. In some cases, company executives can even be held criminally liable.

HIPAA Compliance Alone Does Not Equal Data Security

C-level executives in the healthcare industry may not understand the intricacies of ransomware attacks or phishing schemes, but they do understand the seriousness of HIPAA compliance. They also fall into the trap of thinking that if their organization is compliant with HIPAA, that means their systems are safe. As a result, they devote most or all of their cyber security resources to complying with HIPAA.

HIPAA compliance is crucial – but a cyber security plan cannot start and end with HIPAA compliance.

HIPAA Compliance Is Only a Starting Point to Protect Patient Data

Today’s healthcare IT environment is highly complex. In addition to electronic health records (EHRs), mobile technology, cloud applications, electronic health exchanges, and Internet of Things (IoT) devices are growing in popularity. These technologies are making it easier for healthcare providers to deliver quality care and are improving patients’ lives, but each new gadget and application means new vulnerabilities for hackers to exploit.

In a recent survey of information security experts conducted by the Brookings Institution, most respondents indicated that they felt HIPAA does not sufficiently address modern healthcare data security issues, mainly because the law is light on specifics. HIPAA compliance is primarily about demonstrating that an organization has met certain documentation and procedural requirements. It does not outline precise technical safeguards.

The proof that HIPAA compliance is insufficient to protect against ransomware and data breaches is in the statistics. Healthcare is the most likely industry to experience a data breach. Nearly 90% of healthcare organizations – and 60% of third-party healthcare vendors – have experienced at least one breach. Nearly 80% have had two or more, and nearly 50% have had three or more.

Why Isn’t HIPAA Compliance Enough?

There are several reasons why HIPAA compliance does not provide full data protection on its own. First, it isn’t meant to. Technology simply changes too quickly for any legislation to keep up. By the time a new set of rules were written, they’d already be out of date! This is why HIPAA focuses on what organizations need to achieve, not on precisely how they should go about achieving it. Second, every organization’s IT environment is different. A data security plan that works well at one facility may fall flat at another. Finally, compliance rules cannot adequately address the threats posed by mistakes, negligence, or malicious acts on the part of a facility’s employees, which cause nearly half of all data breaches.

HIPAA compliance should be the starting point – not the entirety – of a comprehensive, proactive healthcare data security plan.

Many healthcare organizations do not have the resources to handle all of their information security needs in-house; many others don’t know where to start. This is why they should partner with a professional cyber security firm such as Lazarus Alliance.

Spear Phishing: Don’t Take the Bait!

Following a string of high-profile incidents that began earlier this year, the healthcare industry has been highly focused on preventing ransomware attacks. IoT security has also emerged as a growing concern. However, healthcare organizations (as well as businesses in other industries) cannot afford to ignore another growing threat: spear phishing.

Like regular phishing, spear phishing involves sending legitimate-looking but fraudulent emails asking users to provide sensitive information and/or initiate wire transfers. However, while regular phishing emails are sent out en masse to the general public, spear phishing emails are highly targeted and sent to specific, predetermined victims, usually a small group of people working at a specific company.

In a recent press release, the Federal Bureau of Investigation warned of a dramatic rise in a type of spear phishing known as a “CEO email scam” or a “business email compromise scam.” According to the FBI, from October 2013 to February 2016, law enforcement identified 17,642 victims, totaling $2.3 billion in losses. Since January 2015, reports of spear phishing have increased by 270%.

Like regular phishing, spear phishing involves sending legitimate-looking but fraudulent emails asking users to provide sensitive information and/or initiate wire transfers. However, while regular phishing emails are sent out en masse to the general public, spear phishing emails are highly targeted and sent to specific, predetermined victims, usually a small group of people working at a specific company.

Main Line Health Attack Proves that Employee Data Is at Risk

In February 2016, while everyone’s attention was focused on the Hollywood Presbyterian ransomware attack, Main Line Health, which operates four hospitals near Philadelphia, was hit by a spear phishing scheme. Emails were sent to employees, purportedly from the organization’s CEO and CFO, requesting employee payroll and W2 information. While some employees immediately realized the emails were fraudulent and reported them to management, at least one employee was tricked into sending the requested information to the hacker. As a result, Main Line Health had to notify its employees that their personal information may have been compromised and offer them free credit counseling and monitoring services.

When healthcare organizations think about cyber security, they usually focus on patient data protection. However, the hackers who compromised Main Line Health were not seeking to infiltrate patient data, but employee data, and the attack may have been connected to a very large spear phishing scheme targeting HR and payroll professionals in various industries nationwide. It is suspected that the hackers running the scheme intended to use the stolen data to file fraudulent tax returns.

How to Protect Against Spear Phishing

Email spam filters can be adjusted to recognize emails from suspicious sources and block them before they reach employees’ inboxes. However, some phishing emails will undoubtedly still get through. The best way to protect against spear phishing is to teach employees how to recognize the telltale signs of a spear phishing email, such as:

  • The salutation and/or the closing seem odd. For example, management normally refers to you as “William” or “Mr. Doe,” but the email is addressed to “Bill.” In the case of Main Line Health, the closing is what alerted one employee to the fraud; the email message, which purported to be from the CEO, was signed “John Lynch,” but the employee knew that the company’s CEO goes by “Jack.”
  • The request is unusual and/or does not follow normal company protocol. For example, the email is asking for employee W2 information, but requests like this are not normally handled through email or by the employee who received the request, or the person who allegedly sent the email has never requested similar information before, or it’s unusual for the person who allegedly sent the email to directly contact that particular employee.
  • The wording and tone of the email are stilted. Many spear phishing attacks are launched by foreign hackers who are not fluent in English; the email may be riddled with punctuation, spelling, or grammar errors, be worded oddly, or use British spelling. The wording may also be overly formal – or overly casual.
  • The domain the email was sent from is incorrect. Instead of “yourcompany.com,” the email may have been sent from “yourcompany.com-xyz.com” or some other derivative.

Employees should be taught that if something seems “off” about an email, they should consult a supervisor or IT security personnel before responding to it. Additionally, as part of your organization’s overall cyber security plan, a firm protocol should be established regarding requests for sensitive employee and patient data, and employees should be trained not to release sensitive data unless the protocol is followed.

In addition to using email spam filters to intercept suspicious messages, training employees to spot spear phishing emails, and implementing a solid security plan that includes protocol for the release of sensitive data, it’s a good idea for healthcare facilities to enlist the services of a professional cyber security firm such as Lazarus Alliance.
