Not only has the number of cybersecurity breaches increased over time, but the diversity in attack methods has expanded and evolved. Here are some of the broad cyber-attack methods that have evolved over the years:

• Malware: Short for “malicious software,” malware is software that a cybercriminal has created to disrupt or damage a legitimate computer network. It often sneaks into a network via an unsolicited email or a legitimate-looking download and, once inside, steals money or launches politically motivated cyber-attacks. Types of malware include spyware, ransomware, adware and botnets.
• SQL injection: SQL (short for “Structured Query Language”) is an attack designed to steal data from a database. Cyber criminals exploit vulnerabilities in data-driven applications to insert malicious code into a database.
• Phishing: Cyber criminals go “phishing” to target victims with emails that appear to be from a legitimate company asking for sensitive information. Phishing attacks are typically used to dupe people into handing over credit card data and other personal information.
• Man-in-the-middle attack: In these attacks, a cyber criminal intercepts communication between two people to steal data. For example, on an unsecure Wi-Fi network, an attacker could intercept data being passed from the victim’s device to the network.
• Distributed denial-of-service (DDoS) attack: In a DNS scheme, cyber criminals prevent a computer system from fulfilling legitimate requests by overwhelming the networks and servers with traffic. Imagine the cars on a typical rush hour freeway riding on the racetrack during the Indy 500. This renders the system unusable, preventing an organization from performing vital functions.
• Business email compromise (BEC): In BEC scams, the attacker pretends to be someone the victim trusts. It usually starts with an email address disguised as belonging to the trusted person—typically a boss, co-worker, vendor, or business partner. Then, the attacker asks the victim to wire money, send a payment to a new account, send sensitive information, and more.
• Email account compromise (EAC): Closely related to BEC, EAC uses identity deception with a twist. In some ways, EAC is even harder to detect and stop than BEC. In BEC, the attacker tries to impersonate a trusted person’s email account. In EAC, the attacker takes over that trusted email account. The email account doesn’t just seem legitimate—it’s the real thing.
• Data breaches: Not only have data breaches become more frequent, but their scale has also grown, leading to unprecedented exposure of personal and financial information. The repercussions extend beyond immediate financial loss to long-term reputational damage.
• Cloud vulnerabilities: While cloud services offer scalability and efficiency, they are not immune to risks such as misconfigurations or inadequate access controls that cybercriminals can exploit. Shared tenancy models further complicate this by potentially allowing attackers a pathway through neighboring systems.
• Cryptojacking: This involves the unauthorized use of someone else’s computing resources to mine cryptocurrency, which not only siphons off processing power but also incurs additional energy costs for unsuspecting businesses or individuals.
• Third-party exposure: Cybersecurity is only as strong as its weakest link—hackers often target smaller partners with less stringent security measures as an entry point into larger organizations’ networks. This underscores the importance of comprehensive security protocols across all tiers of an organization’s ecosystem.
• Configuration mistakes: Simple errors in system configurations can inadvertently open doors for cyber-attackers seeking easy access points into secure environments. Regular audits and updates are essential to minimize these vulnerabilities.
• State-sponsored attacks: Nation-states leverage sophisticated techniques not just for espionage but also for disrupting other countries’ critical infrastructure—raising concerns over national security alongside economic stability.
• IoT attacks: As Internet-connected devices proliferate in both home and industrial settings, so do opportunities for malicious actors to hijack these devices—turning them into gateways to wider networks or forming botnets.

The prevalence and sophistication of these threats underscore the ongoing arms race between cybersecurity professionals and cyber adversaries. As we move forward into an increasingly digitized future, staying abreast of such risks becomes paramount—not just for safeguarding assets but also for ensuring the resilience and reliability of our digital ecosystem.
