To protect themselves from cyber hacks, organizations must remain diligent or suffer the consequences. Read on to learn about the history of cyberattacks and the impact a breach caused by a cyber hacker or malware can have.
43% of cyber attacks target small businesses.
Hackers attack a computer with internet access every 11 seconds.
The average cost of a corporate data breach is $116 million.
Malware: Malicious software such as spyware, ransomware, viruses and worms that breach a network, typically after the user clicks a link or email attachment.
Phishing Attack: Sending fraudulent communications, usually via email, with the goal of stealing sensitive data or distributing malware, typically using social engineering tactics.
Man-in-the-Middle Attack: Commonly known as eavesdropping attacks, cybercriminals insert themselves into a two-party transaction in order to steal data or login credentials.
Denial-of-Service Attack: DDoS attacks flood systems, servers or networks with traffic to exhaust bandwidth, rendering them unable to fulfill legitimate requests.
SQL Injection: Malicious code is inserted into a server that uses SQL, such as a website search box, forcing it to reveal hidden information.
Zero-Day Exploit: This attack targets a known network vulnerability before the company has had time to implement a solution.
DNS Tunneling: Exploiting the DNS protocol and evading firewalls, this attack routes DNS requests to a server controlled by the attacker, which sends malicious data back to the compromised device.
What happened? A cyber worm—malware that propagates on its own without the need for a software host—was deployed by 23-year-old graduate student Robert Tappan Morris. While it did not destroy data, the worm delayed critical military and university communications and functions for several days.
The target: Public and private research centers and prestigious colleges such as Harvard, Princeton, Stanford, Johns Hopkins and NASA.
The outcome: While the cyber hacker claimed it was an experiment gone wrong, evidence uncovered by the FBI suggested otherwise. Morris was indicted in 1989.
Estimated impact: $100,000–More than $1 million
