Privacy breaches: Using Microsoft 365 Advanced Audit and Advanced eDiscovery to minimize impact

GDPR, HIPAA, GLBA, all 50 U.S. States, and many countries have privacy breach reporting requirements. If an organization experiences a breach of customer or employee personal information, they must report it within the required time frame. The size and scope of this reporting effort can be massive. Using Microsoft 365 Advanced Audit and Advanced eDiscovery to better understand the scope of the breach can minimize the burden on customers as well as the financial and reputational cost to the organization.

A changing privacy landscape

In 2005 ChoicePoint, a Georgia-based financial data aggregator had a data breach of 145,000 of its customers. There were multiple security lapses and resulting penalties, but initially, only ChoicePoint’s California-based customers were required to be notified because, at the time, California, with California Senate Bill 1386, was the only state that had a mandatory privacy breach notification law.

Since that time, all 50 U.S. States have put in place mandatory privacy breach notification laws. Countries in the Americas, the Middle East, Europe, and Asia have adopted privacy standards including mandatory breach notification. Broader regulations that address this issue include California Consumer Privacy Act, China’s Personal Information Security Specification, Brazil’s Lei Geral de Proteção de Dados Pessoais (LGPD), and the European General Data Protection Regulation (GDPR). Given how often these laws are added or updated, it’s challenging for any organization to keep up. As one solution, Microsoft 365 Compliance Manager provides a set of continually updated assessments (174 and growing) to assist our customers with these standards.

A board-level business risk

The reputational and financial risk to a company from a privacy breach can be massive. For example, under California Civil Code 1798.80, which deals with the breach of personal health information, there is a penalty of up to $25,000 per patient record breached. For many standards, there are not only regulatory penalties imposed, but also the right of private action by those whose records have been breached (such as, those who have had their records breached can sue for damages, creating financial liability for a company beyond the regulatory penalties).

There are timeframes under which notification must be made. The California Code requires notification to the regulator within 15 days after unauthorized disclosure is detected. Article 33 of GDPR requires notification to the regulator within 72 hours after the organization becomes aware of the breach.

According to a list compiled by the Infosec Institute, the average cost of a data breach in 2019 was $3.9 million but can range as high as $2 billion in cases like the Equifax breach of 2017.

The reputational damage associated with a breach of customer, employee, or other stakeholders’ personal or business information can substantially reduce a company’s value.

The scope of notification (if any is needed at all) and remediation depends on understanding the scope of the breach in a timely fashion. In the absence of reliable information, companies need to make worst-case assumptions that may result in larger notifications, higher costs, and unnecessary hardship for customers and other stakeholders.

Preparation for breach

As security and compliance professionals, our priority is to avoid breaches with a defense in depth strategy including Zero Trust architecture.

Microsoft has comprehensive security solutions for Microsoft 365, as well as compliance and risk management solutions that enable our compliance pillar framework:

But we also must prepare for breaches even as we defend against them. Part of that preparation is putting our organization in a position to scope a breach and limit its impact. This means ensuring we have the data governance and signal in place before the breach happens. Security professionals know that they have to deploy solutions like Data Loss Prevention, firewalls, and encryption to defend against attacks, but they may not focus as much on having the right audit data available and retained, and visualizations and playbooks in place beforehand to scope a future breach.

Use Microsoft 365 Advanced Audit and Advanced eDiscovery to investigate compromised accounts

The Microsoft 365 Advanced Audit solution makes a range of data available that is focused on what will be useful to respond to crucial events and forensic investigations. It retains this data for one year (rather than the standard 90-day retention), with an option to extend the retention to ten years. This keeps the audit logs available to long-running investigations and to respond to regulatory and legal obligations.

These crucial events can help you investigate possible breaches and determine the scope of compromise. Advanced Audit provides the following crucial events:

There are built-in default alert policies that use the Advanced Audit data to provide situational awareness either through Microsoft 365’s own security and compliance portal, through Microsoft’s Azure Sentinel cloud-native SIEM, or through a customer’s third-party SIEM. A customer can create customized alerts to use the audit data as well.

Let’s look at how a customer might use Advanced Audit to investigate a compromised account and scope the extent of a data breach:

In an account takeover, an attacker uses a compromised user account to gain access and operate as a user. The attacker may or may not have intended to access the user’s email. If they intend to access the user’s email, they may or may not have had the chance to do so. This is especially true if the defense in-depth and situational awareness discussed above is in place. The attack may have been detected, password changed, account locked, and more.

If the user’s email has confidential information of customers or other stakeholders, we need to know if this email was accessed. We need to separate legitimate access by the mailbox owner during the account takeover from access by the attacker.

With Advanced Audit, we have this ability. Without it, a customer will have to assume all information in the user’s mailbox is now in the hands of the attacker and proceed with reporting and remediation on this basis.

The MailItemsAccessed audit data item will indicate if a mailbox item has been accessed by a mail protocol. It covers mail accessed by both sync and bind. In the case of sync access, the mail was accessed by a desktop version of the Outlook client for Windows or Mac. In bind access, the InternetMessageId of the individual message will be recorded in the audit record.

We have the ability to forensically analyze mail access via a desktop client or via Outlook Web Access.

We also need to differentiate between the mailbox owner’s legitimate access to a mail item during the attack time period and access by the attacker. We can do this by examining the audit records to see the context of the access, including the session ID and IP address used for access. We match these with other audit records and known good access by the user.

Advanced Audit retains other events like Teams Joins, File Accessed, Messages Sent, Searches Queries, and many others that can support a breach analysis.

When we’ve properly scoped the data that the attacker has had access to, we want to deep dive and inspect the content.

With Advanced eDiscovery we can collect all emails, documents, Microsoft Teams, and Yammer interactions of the account that was taken over. We can search for confidential information and metadata to identify the material in question:

There is metadata for each item which, for emails, includes InternetMessageID as well as many other items such as from, to, and when it was sent, and any Microsoft Information Protection sensitivity label.

Advanced Audit and Advanced eDiscovery are an important part of an effective security risk and compliance strategy. These Microsoft 365 native tools allow our customers to understand the true scope of a breach. It has the potential to substantially reduce or eliminate the reporting requirements stemming from a compromised account. Advanced Audit can reduce the financial and reputational damage to a company, its customers, employees, partners, and other stakeholders.

Hackers Using Fake Trump’s Scandal Video to Spread QNode Malware

Cybesecurity researchers today revealed a new malspam campaign that distributes a remote access Trojan (RAT) by purporting to contain a sex scandal video of U.S. President Donald Trump. The emails, which carry with the subject line "GOOD LOAN OFFER!!," come attached with a Java archive (JAR) file called "TRUMP_SEX_SCANDAL_VIDEO.jar," which, when downloaded, installs Qua or Quaverse RAT (QRAT)

Security Outcomes Report: Top Findings from Around the World

The Security Outcomes Study has been out for a few weeks now and I’ve had time to sit back and read it over with coffee in hand. The report empirically measures what factors drive the best security outcomes. The part that really caught me from the outset was the fact that this was based on a survey wherein the respondents didn’t in fact know that it was for Cisco. I think this is a point that absolutely must be highlighted right from the beginning. It was interesting to look at how the respondents set themselves apart from each other when a geographic lens was focused on the collected data.

To be quite clear, there were many similarities between the different regions around the world. Whether in APJC, EMEAR or the Americas it showed that there is in fact a significant push towards technology refresh in every region. The study shows a significant improvement in security when organizations have a proactive approach to refreshing their IT and security technology. This makes sense because rather than continuing to operate on systems and software that may be deprecated, the study shows that by creating refresh projects, organizations could mitigate a significant amount of security issues that had been lingering for a multitude of reasons. This helped organizations to alleviate some of the accumulated security debt.

To explore how organizations in different countries and regions are successfully achieving each security outcome, visit cisco.com/go/SecurityOutcomes.

Now as we break out into different regions, we see that the priorities tend to diverge. When we look at the data collected from APJC we see that some of the focal points (the squares in the matrix with the darkest shades of blue) such as building executive confidence on threat detection so as to secure more budget are a challenge. This is the top-rated point for the survey from respondents in Asia for this report.

APJC, Asia and Japan, Security Outcomes Report

The data from EMEAR however shows an increase in focus on proactive tech refresh for the goals of satisfying meeting compliance regulations. Here too, as we see in APJC, that cost effectiveness is also important. Timely incident response also registers high on the ranking for working to manage the top security risks facing organizations. The top listed data point for the EMEAR is hands down on working to meet compliance regulations at 11.2%.

EMEAR, Europe, Middle East, Africa, Security Outcomes Report

Now as we shift our discussion to the Americas, we see that the priorities shift. In contrast to APCJ and EMEAR regions, for the Americas this doesn’t register in the data as it pertains to threat detection and security budgeting. There are two items that leap off the page are for priorities in the Americas. First is a focus on running a cost-effective shop with well-integrated technology. The second point which ranks highest overall is the need to retain security talent to help manage the well-integrated technology deployments.

Americas, North America, South America, Security Outcomes Report

This survey was a bit of an eye opener for me personally as I did not expect that a proactive technology refresh program would be as much of a focus for organizations as it is. However, it does make sense. To help manage the accrual of security debt a tech refresh program will go a long way to helping to alleviate the issues introduced by risk management that has not been able to close out issues.

This was really rather amazing reading for a survey driven study and my hat is off to the team who drove this project and the incredible insights that it provides, not only from a sheer statistical point of view but also from the perspective of a regional break out.

A Database Rebuild to Champion the Bayh-Dole Act

Throughout history, many innovative ideas have been realized and brought to life within federal laboratories across the country. From this, it was discovered that there needed to be policies in place to ensure that federal institutions could properly report out about those inventions. The Bayh-Dole Act was ratified in 1980 to deal with inventions that came to fruition in federally funded laboratories. This landmark act provided an easily managed landscape for government agencies to oversee the discoveries from the multi-million, federally sponsored research and development programs. NIST has
