Information systems security failures often stem from unpatched software, weak credentials, or configuration errors, resulting in massive data breaches and operational downtime. Key examples include the 2017 Equifax breach, the 2021 Colonial Pipeline attack, the 2024 Snowflake/Ticketmaster breach, and the 2020 SolarWinds supply chain attack. These incidents highlight the critical need for robust, proactive security measures. Review the following four real-world examples to learn from them.

Information Systems Security Failures
Equifax Data Breach of 2017
The 2017 Equifax data breach exposed the sensitive personal information of 147 million people, primarily in the U.S. Hackers exploited a known, unpatched vulnerability in the Apache Struts web framework to gain access to files containing names, Social Security numbers, birth dates, and driver’s license numbers. The breach led to a massive settlement of up to $700 million.
Key Details of the 2017 Equifax Data Breach:
- Cause: Attackers exploited a vulnerability (CVE-2017-5638) in the Apache Struts framework used on an Equifax dispute portal, which the company failed to patch despite warnings.
- Data Compromised: The breach compromised the names, Social Security numbers, birth dates, addresses, and, in some cases, driver’s license numbers and credit card numbers of approximately 147 million consumers.
- Timeline: The vulnerability was disclosed on March 7, 2017, and exploited between mid-May and July 29, 2017, when the breach was finally discovered.
- Impact: The incident resulted in significant reputational damage, regulatory scrutiny, and a massive settlement to compensate affected individuals for out-of-pocket losses and time spent.
- Response: Equifax offered free credit monitoring and identity theft protection to affected consumers.
- Attribution: The U.S. Department of Justice attributed the attack to members of the Chinese military.
The Federal Trade Commission (FTC) provided a settlement to help affected individuals, with payments for claims already being sent out.
Colonial Pipeline Ransomware (2021) Was An Information Systems Security Failure
The 2021 Colonial Pipeline ransomware attack was a major cyberattack by the DarkSide group on May 7, 2021, that crippled the largest U.S. refined products pipeline. It forced a 5-day shutdown, causing severe East Coast fuel shortages, panic buying, and a federal emergency declaration, and Colonial paid a $4.4 million ransom. Key details of the incident include:
- Target: The company’s IT billing systems were compromised, prompting a proactive shutdown of operational technology (OT) to prevent the infection from spreading, according to GAO and CNN.
- Attacker: The Russia-linked ransomware-as-a-service group DarkSide was identified by the FBI.
- Impact: The pipeline, which supplies about 45% of the East Coast’s fuel, was shut down for 5 days.
- Ransom & Recovery: Colonial Pipeline paid 75 bitcoin (approx. $4.4 million at the time) to regain access.
- Law Enforcement Action: The DOJ later seized 63.7 bitcoin (roughly $2.3 million) of the ransom payment.
Aftermath:
- Supply Chain Disruption: Panic buying created severe gasoline shortages throughout the Southeastern U.S.
- Policy Changes: The attack served as a “wake-up call” for critical infrastructure security, leading to stricter cybersecurity requirements for pipelines.
- DarkSide Response: The hacking group claimed they did not intend to create societal problems, but rather, their goal was solely to make money.

Another Information Systems Security Failure
The 2024 Snowflake breach was a major security incident where threat actors (likely ShinyHunters) used stolen credentials to access over 100+ clients’ cloud data, including Ticketmaster, resulting in the theft of 560 million customers’ personal/financial data. The attack targeted unprotected accounts rather than a breach of Snowflake’s core platform. The following key details explain the incident:
- Impact on Ticketmaster: In May 2024, hackers targeted Ticketmaster, a subsidiary of Live Nation, potentially exposing the names, emails, and payment details of 560 million customers.
- Nature of the Breach: The breach was not a direct attack on Snowflake’s core infrastructure, but rather a targeted campaign using stolen credentials (passwords, tokens) to access specific, improperly secured customer instances.
- Vulnerabilities Exploited: Attackers, identified as the group “ShinyHunters” or using aliases such as “Judische” or “Waifu,” bypassed Multi-Factor Authentication (MFA) and Single Sign-On (SSO) on accounts where these were not enforced.
- Broader Impact: Beyond Ticketmaster, other major companies, including AT&T and Santander, were also affected.
- Discovery: The breach came to light when the database was offered for sale on underground forums in late May 2024.
- Attribution: The attacks were linked to threat actor groups, including ShinyHunters, and stemmed from a broader campaign targeting organizations using Snowflake’s cloud-based data storage.
Outcome: The incident resulted in significant data extortion, direct financial losses, and reputational damage to affected companies.
SolarWinds Supply Chain Attack (2020)
The 2020 SolarWinds supply chain attack was a sophisticated, Russian-aligned espionage campaign that inserted a backdoor (SUNBURST) into the Orion network monitoring software. Roughly 18,000 customers downloaded the tainted update, allowing attackers to steal data from U.S. government agencies and private tech firms for over 10 months. Here’s what happened, including the aftermath of the incident:
- Method: Attackers compromised SolarWinds’ software build system, inserting malicious code into legitimate updates, which were then digitally signed and distributed to customers.
- Victims: Approx. 18,000 users were exposed, though the attackers (often referred to as SolarStorm) targeted a smaller, high-value subset for deeper, long-term espionage.
- Timeline: Activity started around September 2019, with malicious code updates distributed starting March 2020. The breach was uncovered by FireEye in December 2020.
- Techniques: The attackers used “living off the land” techniques, abusing legitimate administrative tools, and performed “Golden SAML” attacks to steal identity tokens, granting them access to cloud services (e.g., Office 365).
- Impact: The breach targeted major U.S. government agencies, including the Department of Homeland Security, and technology companies.
- The attack highlighted the severe risk of software supply chain vulnerabilities.
