Protecting Our Customers: MSP Response to The AT&T Hack and Similar Incidents

In light of AT&T’s recent data breach affecting nearly 109 million customer accounts, we want to reassure our clients about the steps we take as your Managed Service Provider (MSP) to protect your data and respond to potential cyber incidents. Let’s examine the AT&T breach and outline our proactive measures to keep your business safe.

Understanding the AT&T Hack

Before diving into our protocols, it’s crucial to understand what happened in the AT&T case:

1. Scope: The breach affected nearly all AT&T cellular customers, including those using mobile virtual network operators (MVNOs) on AT&T’s network, and AT&T landline customers who interacted with these cellular numbers.
2. Timeframe: The compromised data consists of metadata from nearly all AT&T customers from May 1, 2022, to October 31, 2022, with some records from January 2, 2023.
   • What is metadata? Simply put, it is data about the other data. If you call someone, the data is the words you speak, the contents of the call. The metadata is made up of things like call length, the phone numbers involved, etc.
3. Affected Data: Records of calls and texts, identifying which phone numbers interacted with each other. Some records include cell site ID numbers.
4. Unaffected Data: The breach did not include call or text content, Social Security numbers, dates of birth, or other personally identifiable information.

The AT&T Hack Should NOT Be a Surprise!

The AT&T data breach is just one in a series of recent high-profile cyberattacks that underscore the importance of robust cybersecurity measures. Let’s look at some other recent incidents:

1. Healthcare Sector Under Fire

In June 2024, several London hospitals, including King’s College and Guy’s and St Thomas’ hospital trusts, fell victim to a ransomware attack by the Russian group Qilin. This attack disrupted critical services, including blood transfusions, and potentially compromised sensitive patient data. The incident serves as a stark reminder of how cyberattacks can directly impact human lives and the functioning of essential services.

2. Education Sector Targeted

In August 2023, a Connecticut school district lost over $6 million in a sophisticated cyberattack. The attackers impersonated school officials and vendors in emails, tricking the district into making fraudulent electronic transfers. This case highlights the evolving tactics of cybercriminals and the importance of robust verification processes.

3. Automotive Industry Disrupted

In June 2024, a cyberattack on CDK Global, a major software provider for car dealerships across North America, forced many dealerships to revert to pen and paper for sales and operations. This incident demonstrates how attacks on third-party service providers can have far-reaching consequences across entire industries. CNN reports that CDK most likely paid hackers $25 Million for their data.

4. Government Data at Risk

In 2024, Indonesia’s national data center fell victim to a ransomware attack, with cybercriminals demanding an $8 million ransom. According to the Indonesian Government, they have not paid the ransom. This attack on a government facility underscores that no entity, regardless of size or importance, is immune to cyber threats.

5. Retail and Consumer Data Exposed

In March 2024, AT&T reported another data breach where a dataset containing Social Security numbers for about 7.6 million current AT&T account holders and 65.4 million former account holders was found on the dark web. This incident, separate from the more recent breach, illustrates the ongoing nature of cyber threats and the need for constant vigilance.

These incidents collectively demonstrate several key points:

1. Diverse Targets: Cyberattacks affect organizations across all sectors, from healthcare and education to automotive and telecommunications.
2. Evolving Tactics: Cybercriminals are constantly refining their methods, from sophisticated ransomware to social engineering attacks.
3. Far-reaching Consequences: The impact of cyberattacks extends beyond immediate financial losses, affecting operations, reputation, and in some cases, public safety.
4. Third-party Risks: Many attacks exploit vulnerabilities in third-party systems or providers, highlighting the need for comprehensive supply chain security.
5. Persistent Threats: Even large, well-resourced organizations fall victim to repeated attacks, emphasizing the need for continuous improvement in cybersecurity measures.

As your MSP, we stay informed about these incidents and many others, constantly refining our security strategies to address emerging threats. Our goal is to learn from these real-world scenarios to better protect your business from similar risks.

Our Proactive Measures

The best time to stop a hack is before it happens. Our Managed Cybersecurity program works with your business’ needs and capabilities to increase your security. Note – All security, but especially cybersecurity, is a matter of making the bad outcomes less likely. It also needs to take into account the risks facing an organization, for instance a celebrity has higher physical security needs than most people. Anyone who tells you they can’t be hacked, or they can make it so you can never be hacked, is either foolhardy or disingenuous. The CIA has gotten hacked multiple times. This post is meant to inform, and never to suggest that Nomadic Secure or our customers are immune from hacking and other cybersecurity issues.

1. Continuous Monitoring and Threat Detection

We implement advanced threat detection tools that continuously monitor both your internal systems and any third-party platforms you use. This allows us to quickly identify any suspicious activities or potential breaches. That might look like log-ins from a country you’ve never been to, or an employee suddenly copying your entire shared drive to a location outside your company.

Some of the tools we can employ can be monitored by security professionals, and some are automated. Many seemingly suspicious activities (like taking a vacation) are benign, and sometimes something seemingly innocent is an attack. We work with all our customers to determine what tools, and what level of scrutiny, are appropriate for their environment.

2. Regular Security Audits

We conduct regular security audits of your systems to identify vulnerabilities before they can be exploited. This includes:

• Penetration testing
• Vulnerability assessments
• Review of access controls and permissions

3. Data Encryption and Protection

We ensure that your sensitive data is encrypted both at rest and in transit. This adds an extra layer of protection, making it much harder for cybercriminals to access or use any data they might obtain.

4. Employee Training and Awareness

We provide regular cybersecurity training for your staff, helping them recognize potential threats and follow best practices for data protection.

Our Incident Response Protocol

In the event of a suspected breach, here is what happens:

1. Rapid Detection and Assessment

Our 24/7 monitoring allows us to quickly detect potential incidents. Upon detection, we immediately assess the situation to determine the potential scope and severity.

2. Containment and Mitigation

We take swift action to contain the threat and prevent further unauthorized access. This may involve:

• Isolating affected systems
• Patching vulnerabilities
• Updating access controls

3. Thorough Investigation

We conduct a comprehensive investigation to determine:

• What data, if any, was compromised
• The extent of the breach
• How the breach occurred

4. Client Communication

We believe in transparent communication. We’ll promptly inform you about:

• The nature of the incident
• What data may have been affected
• Steps we’re taking to address the situation
• Any actions you or your employees need to take

5. Remediation and Recovery

We work diligently to remediate the issue and recover any affected systems or data. This includes:

• Restoring from clean backups
• Implementing additional security measures
• Updating incident response plans based on lessons learned

6. Ongoing Monitoring

After addressing the immediate incident, we continue to monitor for any signs of ongoing issues or data misuse.

Continuous Improvement

We’re committed to continuously improving our security measures. This includes:

• Staying updated on the latest cybersecurity threats and trends
• Regularly updating our security tools and protocols
• Conducting post-incident reviews to refine our processes

Your Role in Cybersecurity

While we take extensive measures to protect your data, cybersecurity is a shared responsibility. We encourage you to:

• Promptly install any updates or patches we recommend
• Follow our guidelines for strong passwords and access management
• Report any suspicious activities to our team immediately
