Linking to the official announcement by Canada Post.
The new player in town, Lorenz, has taken credit for the attack. It also appears that Commport Communications did not pay the ransom, estimated to be between $500,000 to $700,000 for the Lorenz group according to estimates provided by BleepingComputer. Like other newer groups, Lorenz, has a public website available via the Tor network to pressure victims into paying. The data, totaling a compressed 35.3 GB, for Commport Communications is now openly available for download via that website, which suggests that Commport refused to pay the ransom.
Interesting to note is the date on the upload. Commport previously released an attack back in November of 2020, but did not believe any data to be compromised at that time. Apparently, they were wrong.
Canada Post has announced a data breach of shipping manifest data associated with 44 of its large business users. The impact is recorded at more than 950,000 records relating customers of those businesses. Shipping manifests contain sender and recipient information that usually includes both names and addresses, and less often email addresses, and phone numbers.
According to CTV News, the data comprised of 97% names and addresses, while the final 3% of records contained an email address and/or a phone number. The attack occurred on May 19th, according to Commport Communications Inc., however, the data compromised was from between July 2016 and March 2019.
Apparently, Commport Communications Inc., notified Innovapost, Canada Post’s IT Service Provider, in November 2020, of a ransomware attack on the organization, but a review at that time determined that no customer data was leaked from Canada Post at that time. I’d be interested in seeing the lessons-learned from that attack, as well as the steps taken to prevent this time of incident from happening again.
At this time the May 19th event hasn’t been attributed to a specific attack vector and may not be related to the November, 2020 ransomware attack, at all.
Supply Chain Attacks
This very well could have been a crime opportunity as we don’t know if any other data was stolen from the Commport Communications environment. Other than Canada Post, they have reference to working with companies such as Walmart, Pepsi, Coca-Cola, P&G, Lowe’s and even Amazon on their website. Regardless of the original intent, this is what is known as a supply chain attack. A supply chain attack is an attack that targets a less-secure element of an organization’s ecosystem. This could be anything from a HVAC provider to a software vendor, or, yes, even an IT provider.
The 2020 Solarwinds attack was a series of supply chain attacks that led to, suspected, Russian-sponsored state actors, believed to be either SVR or Cozy Bear (APT29) gaining access to a number U.S. Government systems including parts of the NSA and the Cybersecurity and Infrastructure Security Agency. Not to mention a number of private and public businesses and governments that we’ll never know about.
Supply chain attacks are the real deal and they work because as business owners we often make the mistake of trusting the security and the systems of the third-parties that we do business with, and sometimes have elevated access within your businesses systems. They’re also complex when done with an intended target, and are therefore oftentimes the mark of an APT (Advanced Persistent Threat).
The National Cyber Threat Assessment 2020 by the Canadian Centre for Cyber Security lists supply chain attacks as one of seven threats to Canadian financial and economic health.
Supply Chain Attack Risk Reduction
The issue here, of course, is that if we wish to build our businesses weÂ must rely on third-parties to provide things such as manufacturing, operations, financial services and support.Â Information and Cybersecurity isn’t about making it difficult for the business to operate, it’s about creating opportunities!
A third-party risk program can be as complex or as simple as you need, but is really all about governance around your vendors and suppliers. Develop processes and procedures for every transaction between your organization and your third-parties, and ensure that staff are appropriate trained in executing and managing them.
Creating a vendor risk assessment, or by using one of the many available online, you can easily create a risk inventory of your vendors and suppliers that can give your business self-assurance that your suppliers and vendors are employing the necessary security controls. Some questions that you may find on such a form might be, “Does the 3rd party provide information security training to all employees, contractors, and vendors?”, and “Does the 3rd party employee firewalls at all points of network egress?”.
This isn’t a one-time process, unfortunately, and should be reviewed and updated annually for maximum benefit. Both, the ISO-27001 and the CyberSecure Canada Certification require reviews on an annual basis so getting into the habit, and documenting that you’re doing it, can be very beneficial in the long-term.
