Major Global Crackdown on Email Compromise Schemes

Some cybercriminals operate a fraudulent scheme that is called a Business Email Compromise (BEC). In this crime, funds are stolen by convincing a person to send a bank wire to a dummy bank account for what the criminals claim is a legitimate transaction. Businesses that conduct operations that frequently make use of bank wires are the main targets for these criminals. Senior citizens and individuals may be targeted as well, especially if they are involved in a real estate transaction.

Under a program called “Operation Wire Wire,” federal law enforcement, with the cooperation of international authorities, were able to make a total of 74 arrests of alleged criminals. 42 were arrested in America, 29 arrests were made in Nigeria, and one arrest was made in each of the countries of Poland, Mauritius, and Canada. The law enforcement efforts in the United States were a coordinated investigation by the Department of Homeland Security, the Department of Justice, the Department of the Treasury and the U.S. Postal Inspector’s Office.

The investigation lasted six months. In addition to making the arrests, the investigation captured $2.4 million of stolen funds and authorities also blocked the illegal transfers of $14 million.

How does a business email compromise scheme work?

The BEC scheme is financial cybercrime. It is a sophisticated fraud that attacks employees with the authority to transfer company funds by bank wire. Businesses that work with foreign suppliers and those that regularly send bank wires are especially vulnerable. This fraud is usually achieved by obtaining the email account of a senior level employee for a company and impersonating this person to direct other employees to send a bank wire to the criminal’s account. Besides stealing money, the criminals may also try to obtain confidential information such as the employee tax records.

This fraud began in Nigeria. Now, through the involvement of transnational criminal groups, it spread across the globe. The use of Americans increased the success of this fraudulent scheme in the United States.

Conclusion

Companies continue to lose millions of dollars each year due to this scam. Consult with the security experts at Sentree Systems Corp. in Indianapolis, serving central Indiana and the surrounding cities of Avon, Carmel, Fishers, Noblesville, and Plainfield. They will help implement a more secure approval process for bank wire transfers, improve email security, and can create an ongoing employee education program to help employees spot criminal business email compromise attempts.

Device Security Risks for the Internet of Things

For many industrial and commercial purposes, there are tremendous benefits, in terms of system management, for increased connectivity with the technological innovations of the Internet of Things (IoT). This also brings many new security issues to consider. A new level of security risk comes from the expansion of the IoT to connect devices. These risks come from connected devices that are communicating in less-than-secure ways. Every piece of equipment that is connected through the IoT may create a security breach.

Risks Caused by Medical Devices

An example of this new type of risk is experienced by healthcare organizations that are becoming aware of the cyber vulnerabilities of medical devices. The U.S. Department of Homeland Security (DHS) issued six alerts since April 2018 advising major healthcare organizations about the security risk of medical imaging equipment and patient monitoring devices. The DHS has a special Industrial Control System Emergency Response Team that is tasked with the goal of discovering vulnerabilities in all types of equipment.

Recent security alerts from DHS include notices about devices with these problems:

  • Improper authentication procedures
  • Personal information exposure
  • Missing encryption
  • Memory read/write vulnerability
  • Denial of service potentials

These risks can cause harm to patients if they are exploited.

Risk Mitigation

Healthcare companies now are encouraged to conduct security audits that include an evaluation of connected medical devices. These organizations must also track and record any security risks found in their operations caused by devices and the remediation steps taken to remove the risk.

The challenges include finding things with vulnerabilities that the organization can update with software security patches, checking for proper configurations, and adding system architecture controls. Other things may need to be fixed by the vendors. There should be an ongoing effort to identify vulnerable devices. Taking them offline to fix them or relocate them may cause operational problems. There is a balance between managing the devices to improve security and understanding the effect on operations when the equipment is not available for clinical procedures.

Conclusion

Companies, especially those in the healthcare industry, need to be aware of the risks caused by devices used in their operations. Contact Sentree Systems Corp. for a security review and to get advice about how to manage security risk caused by devices that are connected to the IoT. Sentree serves Indianapolis, Avon, Plainfield, Carmel, Fishers, Noblesville, and the surrounding areas in Indiana.

The Impact of the New European GDPR Security Regulations on American Companies

New privacy and data security rules are now in effect for any company that has some of its operations in Europe or has some customers from there. The European Union (EU) passed a law called the General Data Protection Regulation (GDPR) that requires businesses to give EU customers more control over how their personal data is collected, what permissions are required for a company to use it, and what can be done with the information. This law went into effect on May 25, 2018.

Any American company that has customers from the EU needs to be in compliance with the GDPR regulations. It is likely that over the next few years similar regulations will be imposed by the U.S. government on companies in the USA as well.

GDPR is in Response to Data Breaches

The GDPR law is in response to the continuing problem of data breaches being experienced by many companies including large online retailers and companies that are tech giants. Facebook got into serious trouble over the Cambridge Analytica data hack of its system.

Under the GDPR rules, any company that has any data on any person from the EU must notify regulators within 72 hours of the discovery of a major data breach. This means that even U.S.-based companies need to be in compliance if they have an office in the EU, share data with a company there, or have online customers from the EU.

Another new GDPR rule requires companies to make it very easy to opt-in and opt-out of data collection. Companies who fail to do this correctly face a fine of up to 4% of their annual level of global sales or about $23.5 million, whichever is a greater amount.

Conclusion

The new GDPR rules are considered the best practices. Many American companies are taking the proactive stance to be in compliance with GDPR regulations even if they are not required to follow the GDPR rules by law. Work with the experts at Sentree Systems Corp. to find out how to change information collection, storage, and usage procedures to be in compliance with the new GDPR rules.

How to Reduce Data Security Breaches Using an ‘Air-Gap’

 

Not all things need to be online. In fact, there are some systems and information that should never be online and instead be secured by a private offline network. This strategy is known as using an “air gap” between systems and the public Internet.

Improved Security Using Offline Systems

Using an offline network for critical path functions and data security reduces the risk of a data breach. This is an excellent strategy, however, it is not 100% secure. In any security review, the IT security experts look at outward-facing systems that connect directly with the Internet, opportunities to manage system networks offline to improve security, and the risk of “human engineering” hacking attempts. Human engineering security breaches come from the tricking people into doing something that allows a security breach. Using an air-gap strategy needs to be enhanced with increased personnel security, such as extensive background checks, limiting personnel access to systems, and physical security barriers to access sensitive data.

Offline Protection of Personal Data

Any organization that handles personal data, such as credit card information or medical records, has a severe obligation to make sure the data is protected. Access to this information should be managed on a need-to-know basis. For example, credit card data only needs to be used for secured transactions. If it is stored by a company that information should be stored offline and secured by encryption.

For medical records, there are severe penalties for data breaches under the Health Insurance Portability and Accountability Act of 1996 (HIPAA). In some cases, these penalties have been in the many millions of dollars. This means anyone handling such data needs to protect it like they are guarding the gold at Fort Knox. This is the kind of information that benefits from offline storage using a private network, with point-to-point information tunnels that pass data from one place to another only when it is encrypted in order to only permit authorized access to the data.

Conclusion

The risk of experiencing a data breach when there is unnecessary exposure of data to the public Internet can be better managed by taking the sensitive data offline.

Consult with Sentree Systems about how to manage an online presence combined with a private offline network for better security. Every business of any size can benefit from this approach.

Data Breaches in the USA – Is your business next?

The U.S. Department of Health and Human Services maintains a database that tracks every data breach of medical records where more than 500 records have been compromised. SafeticaUSA reports that, during 2016, the data breaches were caused by improper disposal of memory storage (2.3%), loss (5.4%), theft (19%), hacking (31.8%), and unauthorized access/disclosure of information (41.5%) by employees, which happens sometimes by accident.

Misuse of this information obtained by a data breach is rampant. Criminals can use this personal data in many nefarious ways including blackmail and identity theft. Businesses that do not protect personal and private data are liable for its misuse. They can face fines and civil lawsuits in the multiple millions of dollars.

The SafeticaUSA study noted that the average cost for a single data breach is $7 million and that 100% of businesses share business data in ways that are not safe. When employees leave a company, 87% of them take company data with them increasing risk exposure.

Indiana’s Data Security Record

In the SafeticaUSA study of medical record data breaches, which reviewed the occurrences in 2016, California was the state with the largest number of incidents, followed by Florida, Texas, and New York. Indiana came in fifth place by having 12 major data breach incidences during 2016. In terms of the number of compromised private records, the state of Indiana, with 257,174 records breached, was in tenth place on the list of states with the highest number of data breaches.

Conclusion

Data breaches are a serious problem that puts every business at risk. Personal medical records are very vulnerable and the dangers are increasing. Proactive strategies to reduce this risk include conducting a data security audit, implementing a data loss prevention solution, and advocating that the best practices are used for data security by affiliates, contractors, and business partners.

Contact Sentree Systems for a Cyber Risk Analysis to improve security and reduce the chance of a serious data breach.

What is Encryption and How to Use it Effectively

When it is used properly, encryption is a valuable tool to help reduce data security breaches. Most business owners and C-level executives know something about the general topic of encryption; however, comprehensive data security reviews consistently show security problems that can be reduced by following the best-practice strategies regarding how to use encryption.

Using Encryption Effectively

Every organization benefits from encryption. Encryption is more effective when it is used comprehensively and always in place. During any part of the data processing, if the data is unencrypted, this creates a point of risk exposure. For example, if a user with authorized access uses an encryption key to decode some encrypted data and then leaves a copy of the unencrypted data on a laptop that they take home, suddenly the entire system is at risk. Encryption is made totally ineffective if an unencrypted copy of the database is on a laptop that can be hacked or stolen.

Avoiding a False Sense of Security

Just because data is encrypted, does not necessarily mean it is protected. There have been many examples of encrypted databases being subject to data breaches because even though the database was protected with encryption, those that had the encryption keys that are needed to read the data failed to protect their encryption key.

An example of this problem occurred in the loss of millions of dollars of cryptocurrency. This happened because the encryption keys, which are the proof of ownership of those assets, were hacked and stolen. They were kept in a database that was not secured. Since the ownership of cryptocurrency is semi-anonymous, protecting the encryption keys is the only way to control the assets. If the keys are lost or stolen the cryptocurrency is simply gone and nothing can be done about it.

Conclusion

To properly implement a comprehensive plan for using encryption effectively, one good strategy is to conduct an IT security review by Sentree Systems that focuses on implementing encryption on a network and protecting the encryption keys.

Businesses of All Sizes Need to Protect their Data

Data security is a viable part of protecting the operations of any business. Think of this analogy. Even if you own a one-bedroom/one-bath home, which is the first home you ever purchased, this does not mean you be lackadaisical about home security. Having an alarm system with solid locks for windows and doors is just as important for your home as these things are in a luxury mansion.

Some might even say since your first home probably represents the biggest investment you have made so far in your life, it needs more protection than the luxury mansion owned by a wealthy family that already owns many other homes. The same logic applies to your business.

IT Security for All

It used to be that IT security was so expensive that only the larger businesses could afford it. Granted, even now, large businesses spend enormous amounts of money on data security efforts because protecting the data from security breaches is so important. However, just because a small business has a modest budget for IT services, this is no excuse for not having a service contract with a high-caliber security firm that specializes in IT data protection.

There are economies of scale that help keep the cost of IT protection modest when using a skilled firm. The security specialists concentrate on data protection. That is what they do best. They think about this 24/7 non-stop on behalf of their clients. Things that they notice affecting other small business clients are applicable for almost every customer they help.

Conclusion

Just because a business is small does not mean that IT security should be inadequate. Being a small business is not an excuse for having poor IT security policies. The cost for failed security measures can be the loss of the entire business. It is very unwise to risk this.

The key to success is NOT to rely only on in-house staff that does not have the time, energy, experience, and expertise to provide state-of-the-art IT security. Instead, outsource these tasks to a company like Sentree Systems and think of the investment as being similar to having a business insurance policy.

Data Security Plans for 2018

The beginning of a new year is a great time to have a comprehensive data security analysis and to create a new strategic data security plan. There is plenty to be worried about when it comes to data security. Data security is something that needs to be constantly monitored in order to be effective. New threats are coming up every day.

Luckily, a small-to-medium-sized business does not have to go at this alone. In fact, having a service contract with a specialist in data security is probably one of the smartest things a business can do.

Here are a few significant things to consider when making a strategic data security plan for 2018:

Internal Security Breaches

It does little to stop a security breach if the entire focus is on external attacks and the security breach comes from within. Authorized users have been known to simply make copies of sensitive data files and walk out the door with them. Disgruntled employees can wreak havoc on data security when leaving a job.

Best practices include using high-quality background checks, restricting access to data on a need-to-know basis, and being able to immediately terminate access for any user.

Ransomware

Ransomware is a type of malware that when a user downloads it, it installs itself, and then encrypts the data on a system to lock the users out. An extortion demand is made for a payment in anonymous cryptocurrency like Bitcoins in order to get the encryption key to unlock the data. These extortion demands range from a few hundred dollars to millions. There is not even a guarantee that paying the ransom will get the data back.

Best practices to avoid this risk are to maintain real-time data backups that are made and then kept in protected storage offline. If a ransomware attack occurs, these backups can quickly bring the organization back to current working-status.

Two-Factor Authentication

All external-facing systems need to have a two-step authentication process using one-time use authentication code for the second step. The benefits of this strategy are significant in blocking unauthorized access. The way it works is an authorized user logs in with a complex password and then the second step sends a text message to a secured mobile device that is used by that person to complete the login process. If the mobile device is lost or stolen the second-step is canceled.

Best Practices for Risk Management

Data Security is improved by taking a data-driven approach that addresses security issues that are uncovered by a review of security risk data. For example, allowing employees to continue to use software that has known vulnerabilities, which has not had the most recent security patch applied, is a risk that is unnecessary.

Here are a few tips to improve Data Security by using a data-driven approach:

Conduct a Security Assessment and Implement Its Recommendations

It is surprising when an organization goes to the trouble to conduct a security Assessment, which should be done on a regular basis and then does not implement the recommendations. Executives may think that since the security Assessment was done, the security is improved. A security Assessment demonstrates an Impact vs. Likelihood that your organization will have a compromise in the near future, but does not actually stop a breach from happening. It is important to take the next steps of implementing security upgrades as well.

Monitor Data Security News Alerts

By setting up Google alerts and keeping an eye on the latest Data Security News, helps increase awareness about security issues. An example of a Google alert is using the name of the software or IT service combined with the phrase “security flaw.” Moreover, there are industry security news systems that can be regularly checked for alerts such as the Security News notifications in the Security Education Companion.

Organizations that do not have sufficient internal staff for these Data Security issues do well by contracting with an outsourced IT data security company to monitor them on behalf of the organization.

Be Proactive About Advanced Persistent Threats

Advanced Persistent Threats (APT) are socially-engineered attacks that are occurring on a continual basis. Examples of APT attacks included phishing where websites are faked to get people to enter private information, email campaigns that cause people to download attachments that are malware, or websites that load malware when a person visits them.

ALERT: Death Threat Scams

What do email scams, death threats and bitcoin have in common? Together they are being used by scammers to steal money from innocent victims. This is by no means a new threat (it’s been around since 2006) but it’s one that’s getting some new recognition. The FBI recently issued a warning about the uptick in these scams and we know if the FBI is talking about it, it’s a big deal.

Threat: Death Threat Scams

Do You Need to Worry: Yup! Everyone is at risk. The scam goes a little something like this: recipient receives a threat via email and is ordered to pay in virtual currency (like bitcoin) or prepaid cards otherwise they or their family will be harmed. Keep in mind that this scam could also come in the form of a text message and they might be after more than just money – they may try to obtain your personal information, account numbers, etc.  

What Can You Do About It: Contact the police immediately and follow their advice. You should also file a complaint with the FBI’s Internet Crime Complaint Center (IC3.GOV).
