Undiscovered vulnerabilities pose a real business risk: a single undetected exploit can paralyze entire business processes, compromise sensitive data or cause millions in damage. Those who do not actively secure their digital infrastructure run the risk of becoming collateral damage in the global cyber conflict.
The digital race between attackers and defenders is a constant sprint. Especially when it comes to zero-day vulnerabilities. This refers to security vulnerabilities that are not yet known to manufacturers at the time of the attack. Such exploits often remain undiscovered for a long time and are used in a targeted manner before there is even an antidote.
The problem is that zero days are hidden everywhere, in operating systems, applications and firmware. They act like digital natural disasters, inevitable but difficult to predict.
attack before defense: Who wins the race?
As soon as a zero day is discovered, whether by manufacturers or security researchers, organizations are faced with a dilemma: transparency or secrecy?
Manufacturers can communicate the gap openly and patch it quickly. Hackers, on the other hand, try to develop working exploits as quickly as possible, often much sooner than security managers can react.
The fact is: In many cases, the attackers are faster. They can get into systems unnoticed long before defenders can intervene. Even well-equipped security teams often discover such activities too late.
Zero days as a business model
Zero-day exploits have long since become a global shadow currency. Security vulnerabilities and associated attacks are traded for large sums of money on specialized platforms. This has created a veritable market for "exploitation-as-a-service": professional hacker teams deliver attacks to order. Payment is made per compromised system or user.
State actors are also making targeted use of zero days, for example to monitor political groups, for espionage or even as a strategic means of exerting pressure.
transparency desired, but politically sensitive
An open approach to zero days would be desirable in terms of global IT security. However, geopolitical interests, legal frameworks and economic considerations often mean that zero days are "hoarded" rather than published.
In authoritarian states in particular, this approach is deliberately encouraged, for example with their own laws, cyber armies and digital arsenals.
What companies actually fail at
Reality shows that even known vulnerabilities do not automatically lead to greater security. There are many reasons for this:
🔴 Incomplete or delayed patches 🔴 Cross-site scripting 🔴 Security gap / security poverty 🔴 Middleware manufacturers (drivers, firmware) as a supply chain risk 🔴 Vendor lock-in 🔴 Legacy IT in production
Strategies against zero days
There is no such thing as 100% security. But companies can significantly improve their defense through a holistic and multi-level approach:
State cyber power: when national interests become a digital threat
The reality: State-affiliated hacker groups have long been part of the geopolitical order Cyber attacks are no longer the work of individual actors. State-supported hacker groups play a central …
The strategies of the attackers: Cybercriminals rely on a combination of different techniques to achieve their goals. The main strategies include: Mail bombing: A flood of emails to overwhelm the …
