The most common hacks leverage human error and system vulnerabilities, with phishing, malware/ransomware, and password-based attacks leading the list. These methods, including social engineering and credential stuffing, often exploit weak user security, outdated software, or unsecured networks to gain unauthorized access.
Malware is the most common type of cyberattack, mostly because this term encompasses many subsets such as ransomware, trojans, spyware, viruses, worms, keyloggers, bots, cryptojacking, and any other type of malware attack that leverages software in a malicious way.
10 Most Impactful Data Breaches Ever
Top 20 Most Common Types Of Cybersecurity Attacks
Let's dive into some of the most common cyber attack vectors:
Computer hackers in the USA go to jail for 10 years for a first offence, and a recidivist gets up to 20 years in prison. In addition, any attempt to cause damage to computers will result in serious problems.
Black Hat Hacker (a.k.a. the Bad)
Their activities may include stealing sensitive information, financial fraud, or causing disruption for political or ideological reasons. Black hat hackers are a significant threat to cybersecurity, as they constantly seek to exploit vulnerabilities in systems and networks.
This law makes it a federal crime to gain unauthorized access to “protected” computers (otherwise known as “hacking”) with the intent to defraud or do damage. It also makes it illegal even to conspire or attempt to commit hacking, even if you didn't follow through with it or were not successful.
There are four primary types of attack surface in modern security threats: cyber (web applications, cloud, IoT), physical (devices, servers, stolen devices), human (phishing, insiders), and social engineering (pretexting, baiting).
Security Cameras and Smart Home Devices
These devices are highly susceptible due to weak default passwords, outdated firmware, and exposure to public internet connections [1].
Malicious Insider or Whistleblower
The chances of being hacked depend on various factors, including the effectiveness of your security measures, the sophistication of hackers, and their knowledge of the vulnerabilities in your systems. On average, businesses have a 1 in 5 chance of experiencing a cyber incident with impact.
“It is terrifying.” He said the average age of anyone arrested for a crime in the U.S. is 37, while the average age of someone arrested for cybercrime is 19, The Wall Street Journal reports.
Grey hat hackers are a unique subset of computer experts who exist between white hat and black hat hacking. The term grey hat refers to an individual who operates without malicious intent but still violates laws or acceptable standards of behavior by exploiting security vulnerabilities without permission.
On an Android phone, the threat is clear. A malicious app or suspicious app can hide, using your phone's camera without your knowledge. Bitdefender Mobile Security for Android gives you the power to fight back.
As of Jan 18, 2026, the average annual pay for an Ethical Hacker in the United States is $135,269 a year. Just in case you need a simple salary calculator, that works out to be approximately $65.03 an hour. This is the equivalent of $2,601/week or $11,272/month.
While this is a terrifying scenario, it is highly unlikely. Causing mass outages across an entire country and compromising all critical networks simultaneously, including ISPs, satellite networks, and radio transmissions, is far-fetched in our current world.
The most common causes of a cyberattack include:
China is by far and away the biggest source of hacking with nearly half of all attacks originating from the country. The US also houses its share of hackers – perhaps unsurprisingly, given that the US pretty much leads the charts for any web stat. What's amazing is tiny Taiwan's contribution to the total.
