I'm trying to understand how realistic hacking is compared with crimes like breaking into a house or attacking someone. A person might have the ability to cause harm but avoid doing so because they could be identified and investigated. Is hacking similar—are attackers generally capable of targeting almost any ordinary computer but held back mainly by the risk of leaving traces and getting caught?
More specifically, can an attacker compromise a typical, reasonably maintained computer without the victim interacting with them, revealing credentials, or exposing much information online? Or do most computers have defenses that make many hacking tools and attacks fail outright? I assume cybersecurity is different from physical crime because encryption, software versions, configurations, and other technical limitations can prevent an attack entirely. Is an average computer more like a fragile house with an easy-to-break window, or more like a heavily reinforced structure where an attacker first needs to find a specific weakness?

People are often the easiest route in, because phishing, reused passwords, and social engineering can bypass strong technical controls. But if you exclude victim interaction and assume the computer is reasonably updated, the situation is much less predictable. An attacker may be able to scan for exposed services or known flaws, but they cannot assume that an ordinary computer is automatically vulnerable to every tool.
Hackers generally need two things: a weakness and the ability to recognize and exploit it. Sometimes weaknesses are found through research or observation, and sometimes attackers rely on mistakes or poor configurations. If the relevant flaw doesn’t exist—or has been patched—the attack may fail regardless of whether the attacker is worried about being traced.
The risk of detection matters, but it isn’t the main reason every computer is not compromised. Technical defenses, secure configurations, encryption, updates, and simple lack of a suitable vulnerability can stop an attack before it gets anywhere.
No—there isn’t a universal tool that can break into any computer. Successful attacks usually depend on a specific vulnerability in the target’s operating system, applications, configuration, or network. Without knowing anything about the target, an attacker can’t simply bypass security by guessing.
A device on the same network may reveal some technical information, but discovering that information doesn’t automatically provide a path to taking control. The attacker still needs a usable weakness and a way to exploit it.
