Real-world cases from Equifax to Razer illustrate the human and financial toll of cyberattacks.
A security breach rarely announces itself. It begins with a misconfiguration, an unpatched vulnerability, or a single employee clicking the wrong link — and ripples outward in ways that can take years to resolve.
The consequences are tangible. Reputations built over decades can erode within days. Affected customers must be notified, many will seek compensation, and some will move to competitors. Employees may leave. If hackers vandalize a website — even changing only a phone number or address — the damage to credibility can be disproportionately large and surprisingly hard to detect.
“A security breach could also have a devastating impact on competitiveness if hackers get their hands on confidential documents, trade secrets, and intellectual property.”
In 2020, gaming brand Razer suffered a data breach when a cloud cluster was misconfigured and left exposed to the public internet. A security consultant discovered it — but not before sensitive customer data had been accessible for weeks, potentially enabling social engineering attacks against roughly 100,000 customers.
In 2017, Equifax — one of the largest consumer credit agencies in the United States — disclosed that attackers had exploited a vulnerability in its web application software to access the sensitive personal data of millions of customers. Equifax’s response compounded the damage: it set up a dedicated breach-notification site under a new domain rather than a subdomain of equifax.com, which made it trivial for criminals to create convincing lookalike sites designed to harvest more personal information from worried customers.
Also in 2017, the Persirai IoT botnet targeted over 1,000 models of internet-connected cameras. More than 122,000 cameras were hijacked and used to carry out distributed denial-of-service (DDoS) attacks — floods of traffic designed to overwhelm targeted systems — all without the knowledge of their owners. The malware was designed to delete itself after execution, running only in memory to avoid detection.
Threats come from both outside and inside an organization. External attackers exploit network vulnerabilities, gain unauthorized access to devices, and use social engineering. Internal threats — whether from negligent employees, contractors, or trusted partners — can be equally damaging: mishandled data, infected USB media, malicious links clicked without thought, all can compromise the network from within.
