Data Breach Simulation Playbook

by Michael Bruemmer 3 min read April 4, 2022

What if there was a way to assess your data security readiness before a breach happens?

Imagine the worst thing that could happen to your organization. Your system is hacked, exposing proprietary and confidential information including upcoming projects and consumer data. Consumer identity theft incidents skyrocket under your name. Competitors begin to take notice and pounce on their opportunity to move into your customer base. Your employees begin to fear for their job security and your consumers fear for their financial safety.

With so much at stake, you need to have a solid plan in place before a data breach occurs.

The best way to improve your organization’s cybersecurity is by conducting data breach simulation, which means testing yourself for vulnerabilities before threat actors do.

Verizon’s Data Breach Report shows that 85% of breaches involved a human element, while only 3% involved vulnerability exploitation.[1] Unfortunately, humans are prone to error. According to the results of Terranova Security’s 2020 Gone Phishing Tournament, almost 20% of all employees are likely to click on phishing email links.[2]

Verizon’s report also found that stolen or misused credentials were responsible for 61% of data breaches. The most dangerous passwords to have stolen are those that provide privileged access to your organization’s networks. It is critical to have a Password Manager to protect your assets.

Experian offers data breach simulation and breach response exercises that test your digital defenses. We will assess what you can do before, during, and after a simulated attack to enhance your response plan.

Before:

  • Consider how often you want to run these tests. They can take place once a year, every six months, quarterly, monthly or any other desired frequency.
  • Determine if you want to use in-house staff or hire internal teams to conduct the exercises.
  • Research potential threat actors who are most likely to target your industry and compile a list of possible aims and methods for each one.
  • Identify targets and also non-targets — resources that are off-limits.
  • Form clear objectives. For example: Infiltrate specific business network, steal the credentials of the IT administrator, and exfiltrate financial data.
  • Define the parameters of the plan by determining where the simulated attacker got their information (i.e., insider information or public knowledge) and what they would know.

During:

  • Launch the attack (Example: send a phishing email to get a victim to install malware through link)
  • Monitor both physical and digital access points
  • Take note of departments and staff that are most likely to be targeted in an attack.
  • Assess internal threats and openings for security breaches.

After:

  • Review incident response plan with gap analysis
  • Did an internal employee make an error of opening a malicious email attachment?
  • Did the simulated attacker gain access to an area they shouldn’t have been in?
  • Did any alerts go off in the process, or fail to go off?
  • Was physical security able to stop threats on the ground?
  • Rank vulnerabilities and weak spots in order of which need to be fixed first.
  • Test the changes by repeating the attack to see if the problem has been solved.

The best way to fight a threat actor is to understand their methods and fix your vulnerabilities before they can be exploited. Through data breach simulation attacks, you can find out where your weaknesses lie before an actual attack takes place and let the assessment inform the development of risk mitigation strategies and action plans.

Consumer visibility is changing Roughly 45 million Americans, or 1 in 5 consumers, are considered credit invisible or unscoreable.[1] They’re working, paying bills and participating in the economy, yet many are not fully visible during the lending process. That creates both a visibility challenge and a growth opportunity for lenders. In this Ask the Expert session, Corliss Hill, Senior Director, Inclusion and Belonging at Experian, joins Dr. Vaneesha Dutra, Endowed Professor of Finance at Morehouse College, to discuss how evolving consumer behaviors are reshaping conversations around financial inclusion and lending decisions. For lenders, visibility matters because confident decisions depend on reliable context and insight. Broader consumer signals can help institutions better understand repayment behaviors, financial stability and consumer capacity. “The benefit of banks using alternative data is that they capture a very significant and new consumer base. That's 20% of the population, 45 million Americans.”Dr. Vaneesha Dutra, Endowed Professor of Finance A more complete understanding of today’s consumers Today’s consumers often manage obligations across a wide range of payment types and financial channels, creating additional signals through cash flow activity, recurring payments and consumer-permissioned financial data. Rent, utilities, subscriptions and mobile phone payments can all provide meaningful insight into how consumers manage their financial lives. What’s changing isn’t the need for risk assessment. It’s the amount of consumer behavior lenders can now evaluate. For example, a consumer experiencing temporary financial disruption may fall behind on certain obligations while continuing to consistently pay rent, utilities and phone bills. Those recurring payment behaviors can provide important context into financial priorities and stability. “These are consumers that pay rent on time every month, pay utilities every month on time and meet many other financial obligations in a timely manner.”Dr. Vaneesha Dutra, Endowed Professor of Finance From visibility to more-informed decisioning Broader consumer insights may help lenders move from limited visibility to more informed decisioning. The conversation shifts when lenders move from asking: “Should we take a risk on this consumer?” to: “Do we have enough information to fully understand this consumer?” That broader context can help institutions: Strengthen risk assessment. Identify financially active consumers with strong repayment behaviors. Support more informed lending strategies. Alternative data isn’t about replacing established credit approaches. It’s about helping lenders build on trusted credit foundations with additional context and insight. Responsible lending starts with better context For lenders, the path forward is practical and actionable. As lenders evaluate broader consumer behaviors, three priorities become increasingly important: Modernize data strategies Incorporate broader consumer signals alongside existing credit data to create a more holistic view of repayment behavior and financial stability. Engage consumers earlier Earlier intervention may help lenders better support consumers before financial challenges become more severe. Create pathways to financial access Smaller lending opportunities can help consumers establish stronger financial profiles and demonstrate positive repayment behaviors over time. The institutions that lead will be the ones that can combine strong risk practices with a broader understanding of consumer behavior. Whitepaper: Bridging the credit divide: income, risk and inclusion in consumer finance Building on the themes discussed in this Ask the Expert session, Dr. Dutra explores how demographic shifts, evolving borrower behaviors and broader consumer visibility are reshaping lending strategies and what they mean for lenders seeking to balance growth, risk management and financial inclusion.

Electric Vehicle Registrations Are Growing Beyond Traditional Locations

For years, most electric vehicle (EV) adoption has been concentrated in California, New York, and other traditional early-adopter markets. And while those markets still lead the nation in total registrations, as of last year, some of the fastest-growing EV markets are in regions that haven’t played a significant role in the past. According to Experian Automotive’s 2025 EV Year in Review Report, EV adoptions seem to be entering a new phase that is spreading well beyond coastal strongholds. In fact, the top designated market areas (DMAs) that saw the fastest year-over-year growth for new retail individual EV registrations in the last five years were Detroit, MI (34.5%), Naples, FL (32.6%), Atlanta, GA (20.6%), Buffalo, NY (18.7%), and Charlotte, NC (17.3%). However, despite the growing demand in these market areas over the last few years, Los Angeles, CA still holds a strong lead in new retail individual EV registrations, with over 164,000 new adopters in 2025. Rounding out the top five were San Francisco, CA (85,000+), New York, NY (78,000+), Miami, FL (45,000+), and Seattle, WA (35,000+). EV adoption expanding well beyond the early-adopter markets could be a result of charging infrastructure growth, vehicle availability improvement, and consumer interest reaching new levels across the country. What does this mean for dealers? The extension of EV adoption into emerging markets signals that these vehicles are becoming a mainstream consideration for more consumers. As dealers look for ways to grow their presence in this segment, adopting marketing strategies, service operations, and inventory planning will be beneficial to meet changing buyer expectations and capitalize on the growing demand. The biggest takeaway isn’t necessarily which markets are selling the most EVs, it’s seemingly where adoption is gaining momentum. As new regions start to embrace these vehicles, it’ll be important to monitor the next phase of growth and where future opportunities may emerge.
