team members.
5. Mobile apps: Mobile apps can be used to provide incident response team members with
access to relevant information and tools, such as checklists and playbooks, while in the
field.
By leveraging technology, organizations can improve their incident response efforts and respond
more effectively to security incidents. It is important to select the appropriate technology tools
and ensure that they are properly configured and used effectively in order to maximize their
benefits.
Working with law enforcement
Law enforcement can be a valuable resource during a security incident, particularly in cases
where the incident involves criminal activity. Here are some ways that law enforcement can
help during a security incident:
1. Provide expertise: Law enforcement agencies have expertise in investigations and can
provide guidance on how to gather and preserve evidence in a manner that is admissible
in court.

2. Assist with tracking down perpetrators: If the incident involves criminal activity, law
enforcement can help track down the perpetrators and bring them to justice.
3. Provide resources: Law enforcement agencies often have access to resources, such as
forensic labs and specialized personnel, that can be useful in the response to a security
incident.
4. Coordinate with other agencies: Law enforcement agencies can coordinate with other
agencies, such as the FBI or Secret Service, to provide additional resources and expertise
as needed.
It is important to establish a relationship with your local law enforcement agency and to have a
plan in place for how to engage them in the event of a security incident. By working with law
enforcement, organizations can better protect themselves and their assets during a security
incident.

Chapter 7: Incident Response in the Real World
Mini Case studies of successful incident response
CoinDesk response to international HR phishing scam
The leading platform that specializes in Bitcoin and Digital currencies faced a unique challenge
in the summer of 2022. People were following up with the companies VP of People & HR about
roles they had applied to or saw a post about. HR quickly determined that these were not real

and engaged the security team along with internal employees. At the same time they also
shared with their network to ensure that job applications were only submitted via official
methods such as LinkedIn. The security team immediately sprang into action to get detailed
information about the infrastructure of the malicious domain. Through DNS queries and
performing OSINT it was determined that these servers were being hosted in Germany, Africa,
and the UK using various cloud resources to limit single point of failure.
After analyzing and collecting sufficient details the scope and impact was determined. A report
was generated for management and individuals who are part of the Incident Response Team to
be aware of their responsibilities during this event. The initial actions were to inform people
applying to the company to be aware of the issue, report this issue to the various cloud
providers, submit URLs as malicious to numerous security vendors, and collaborate with
agencies such as US-CERT & FBI IC3 for increased awareness.
The security team noticed that when it comes to copyright issues, these can be lengthy and
cloud companies might not respond right away. Also, it was quickly discovered that there are no
“International Copyright” protections. Taking matters into their own hands the security team
submitted a fictitious job application with encoded messages and using the address of an FBI
field office. Any hacker who received encoded messages or a payload signaling that they’ve been
discovered would be immediately covering their tracks and tearing down infrastructure. Which
is exactly what happened in this case, the malicious domain with international infrastructure
was taken down the next day. For more details, read this article, “ How Security & HR Teamed
up to take down an employment scam,” published by Sam Blum on the matter.
Capital One swift response and fix to Zero-Day Vulnerability in AWS
Capital One has been previously rated with the #1 most innovative company using business
technology in 2016. Through the years they’ve even hired more AWS certified professionals
than other industries. As any security professional would confirm that there is no such thing as
a secure system, except the one that is powered off and at the bottom of the golden gate bridge.
In 2019, Capital One experienced a significant cyber incident that exposed the personal
information of over 100 million individuals. Here are some steps that Capital One took in their
response to the cyber attack. The company notified affected individuals: Capital One notified
affected individuals and provided them with information about the steps they could take to
protect themselves.
The organization launched an investigation: Capital One launched an investigation into the
incident and worked with law enforcement and cybersecurity experts to identify the cause of

the breach and the extent of the damage. Customers were provided credit monitoring and
identity protection services: Capital One provided credit monitoring and identity protection
services to affected individuals to help them protect themselves against potential fraud or
identity theft. Enhanced security measures were applied, Capital One implemented additional
security measures, including upgrading its firewall and implementing multi-factor
authentication, to prevent future breaches. Some of the challenges that Capital One faced were
legal consequences. Capital One faced legal consequences, including class action lawsuits and
regulatory fines, as a result of the breach. Which was interesting because 30 other companies
were targeted and the headlines only focused on Paige Thompson targeting the bank, probably
because it was a larger story. Additionally, through the investigation it was confirmed that the
data stolen was not accessed nor used for fraud.
By taking these steps, Capital One was able to respond to the cyber attack and take steps to
protect affected individuals and prevent future breaches. It is important for organizations to
have a plan in place for responding to cyber attacks and to take steps to protect affected
individuals and prevent future incidents.
Google blocked and maintain resiliency against the largest DDoS attack
ever
With heavy internet-facing workloads, organizations face increased risk of distributed
denial-of-service (DDoS) attacks. To mitigate the risk, Google created Cloud Armor for Cloud
customers to leverage the scale and capacity of Google’s network edge to protect their
environment from DDoS attacks.
This proved to be a valuable resource for a Google Cloud Armor customer on June 1, 2022.
This customer “was targeted with a series of HTTPS DDoS attacks which peaked at 46 million
requests per second. This is the largest Layer 7 DDoS reported to date...” [1]
This customer was
proactive in adopting a resource that could detect potential risks and vulnerabilities. In this
instance, the Cloud Armor Adaptive Protection detected and analyzed the traffic early in the
attack lifecycle at more than 10,000 requests per second (rps), before quickly ramping up to
100,000 rps. The customer deployed the recommended protective rule before the attack was
fully engaged. Cloud Armor blocked the attack effectively protecting their organization from a
security incident and ensured the end-user’s uninterrupted service. The attack continued to
increase to 46 million rps within a few minutes, but due to the protective rule, Cloud Armor was
blocking the traffic and, ultimately, the attacker(s) relented.
The customer prepared for potential incidents by configuring their Cloud Armor security policy to
establish a baseline model of normal traffic patterns for their service. So, when an attack
occurred, their Adaptive Protection was able to detect the DDos attack early in its life cycle and

generate a protective rule to block the attack traffic. “As the attack ramped up to its 46 million
rps peak, the Cloud Armor-suggested rule was already in place to block the bulk of the attack
and ensure the targeted applications and services remained available.” [1]
As attacks are a near guarantee, a robust strategy must be in place to detect attacks and
protect your applications and services. “This strategy includes performing threat modeling to
understand your applications’ attack surfaces, developing proactive and reactive strategies to
protect them, and architecting your applications with sufficient capacity to manage unanticipated
increases in traffic volume.” [1]
Common pitfalls to avoid
Incident response can be a complex and challenging process, and there are several common
pitfalls that organizations can encounter. Here are some common pitfalls when doing incident
response:
1. Lack of preparedness: Without a robust incident response plan and appropriate training,
organizations may be unprepared to effectively respond to a security incident.
2. Lack of coordination: Without proper coordination among incident response team
members, the response to a security incident may be disorganized and inefficient.
3. Lack of communication: Poor communication with stakeholders, such as employees,
customers, and leadership, can lead to confusion and mistrust during an incident.
4. Lack of resources: Insufficient resources, such as personnel, tools, and funding, can
hinder an organization's ability to effectively respond to a security incident.
5. Lack of post-incident review: Failing to conduct a post-incident review to identify
lessons learned and opportunities for improvement can lead to the same mistakes being
made in future incidents.
By avoiding these pitfalls, organizations can improve their incident response efforts and better
protect themselves in the event of a security incident. It is important to be proactive in incident
response and to have a well-planned and well-executed incident response process in place.
Best practices for incident response professionals
Incident response professionals play a crucial role in protecting organizations from security
incidents. Here are some best practices for incident response professionals:
1. Be proactive: Incident response professionals should be proactive in identifying
potential threats and vulnerabilities, and take steps to prevent incidents from occurring.
2. Stay informed: Stay informed about the latest threats and vulnerabilities, and stay
up-to-date on best practices and techniques for incident response.

3. Have a plan: Develop a robust incident response plan that is well-documented and
tested, and ensure that all team members are trained on the plan.
4. Coordinate with other stakeholders: Coordinate with other stakeholders, such as law
enforcement, IT, and leadership, to ensure a coordinated and effective response to
incidents.
5. Communicate effectively: Communicate effectively with stakeholders, including
employees, customers, and leadership, to keep them informed about the status of the
incident and any steps being taken to address it.
6. Conduct post-incident reviews: Conduct post-incident reviews to identify lessons
learned and opportunities for improvement, and update the incident response plan as
needed.
By following these best practices, incident response professionals can effectively protect their
organizations from security incidents and minimize their impact. It is important to be proactive
and well-prepared in order to effectively respond to security incidents.
