This broad category includes viruses, worms, Trojans, spyware and ransomware. Malware can infect systems through various means, such as email attachments, malicious websites or infected removable drives. It can cause damage ranging from data theft and system crashes to complete network takeovers.

  2. Phishing and social engineering

    Phishing is a type of social engineering attack that tricks users into revealing sensitive information, such as login credentials or financial data, by masquerading as a trustworthy entity via email, text message or social media. Attackers often employ psychological manipulation techniques to exploit human vulnerabilities and bypass technical controls. Spear phishing, a targeted variant of phishing, uses personalized information to increase the likelihood of success.

  3. Ransomware

    Ransomware is a particularly destructive form of malware that encrypts a victim’s files and demands a ransom payment in exchange for the decryption key. Ransomware attacks can cripple an organization’s operations, leading to significant financial losses and reputational damage. The rise of ransomware-as-a-service (RaaS) models on the dark web has lowered the barrier to entry for cybercriminals, fueling a surge in attacks.

  4. Insider threats

    Insider threats originate within your organization, either through malicious intent or negligence. Disgruntled employees, contractors or partners with access to sensitive data can cause significant harm by stealing intellectual property, sabotaging operations or leaking confidential information. Unintentional insider threats, such as falling for phishing scams or using weak passwords, can also introduce vulnerabilities.

  5. Advanced persistent threats (APTs)

    APTs are sophisticated, stealthy and continuous cyberattacks often orchestrated by nation-states or well-funded criminal groups. These attacks target specific organizations or sectors and employ a combination of advanced techniques, such as zero-day exploits and custom malware, to gain and maintain unauthorized access to networks over an extended period. APTs are notoriously difficult to detect and can result in extensive data exfiltration or sabotage.

  6. Cloud and third-party risks

    As organizations increasingly adopt cloud computing and outsource critical functions to third-party providers, they expose themselves to new cyber risks. Misconfigured cloud storage, insecure APIs and shared responsibility models can introduce vulnerabilities that attackers can exploit.
