Lessons from high-profile cyberattacks (2010–2025)
SolarWinds hack (2020)
One of the most sophisticated supply chain attacks ever, Russian hackers inserted malicious code into SolarWinds’ Orion software update. This attack impacted approximately 100 U.S. companies and federal agencies, including major players like Microsoft and Cisco. It highlighted vulnerabilities in trusted third-party software and supply chains and demonstrated that complex, layered security is essential but not foolproof. This incident forced CISOs to rethink vendor trust, implementing network segmentation and stricter audits.
Equifax data breach (2017)
This breach exposed sensitive information of approximately 147 million people due to the failure to patch a known vulnerability in Apache Struts. It cost billions and underscored the critical importance of timely patch management. Equifax’s breach led to increased regulatory scrutiny and numerous customer lawsuits.
CrowdStrike outage (2024)
Though not a direct hack, CrowdStrike faced a major IT outage caused by a software upgrade gone wrong. The Microsoft system crash affected 8.5 million devices worldwide, resulting in widespread service disruptions across airlines, broadcasters, and financial services. This incident underscores how even cloud security leaders face risks from operational errors.
AT&T data breach and class action (recent)
A recent class action settlement related to an AT&T data breach pays up to $7,500 per affected client. This reflects the rising legal and financial consequences of data breaches and emphasizes the importance of robust incident response, compliance, and transparency.

Why cyber risks persist even with large teams and experts
Rapid digital transformation and complex ecosystems create numerous attack surfaces. Third-party and vendor risks remain significant despite comprehensive audits. Human error, misconfigurations, and operational glitches continue to be common entry points. Meanwhile, cyber adversaries constantly evolve, leveraging automation and AI-enhanced methods. Internal IT teams often face overwhelming alerts, resource shortages, and skill gaps, making defense even more challenging.The double-edged sword of artificial intelligence in cybersecurity
AI is increasingly deployed to detect threats faster, automate responses, and predict attacks. However, hackers also use AI to develop more effective phishing campaigns, voice impersonations, and deepfake scams. AI-powered hacking enables convincing voice calls or videos impersonating family members, escalating scams that blur the lines between social engineering and cybersecurity breaches. Organizations need to balance deploying AI defensively while understanding and preparing for its exploitability by bad actors.Key takeaways for enterprises and CISOs
No system is invincible. Multifaceted defense strategies including zero trust architectures, network segmentation, and continuous monitoring are critical. Vendor and supply chain risk management must be rigorous, featuring regular audits and restricted access control. Incident response readiness and transparent communication with affected customers can substantially reduce damage and legal exposure. AI integration should proceed cautiously with ethical usage policies and continuous adversarial testing. Workforce training and addressing cybersecurity talent shortages remain foundational to building resilient defenses.
