Phishing as Primary Method

Phishing remains the most common method attackers rely on to breach organizations in 2025, exploiting human vulnerabilities to gain access. You might receive convincing emails that look legitimate, prompting you to click malicious links or share sensitive info. Attackers often:

  1. Pose as trusted contacts or companies, creating urgency to prompt quick action.
  2. Use convincing logos and language to mimic official communications, lowering suspicion.
  3. Link to fake login pages that harvest credentials when entered.

These tactics exploit your trust and often bypass technical defenses. Once inside, attackers can access networks, steal data, or deploy malware. Phishing’s success depends on manipulating human behavior, making awareness and vigilance your best defenses against these pervasive threats.

Supply Chain Vulnerabilities

Supply chain vulnerabilities have become a prime target for cybercriminals seeking to maximize their impact, as attackers often exploit weaker links within third-party networks and service providers. These vulnerabilities enable hackers to bypass traditional security measures by infiltrating less protected systems, then moving laterally to access sensitive data. Common attack vectors include compromised software updates, malicious third-party vendors, and misconfigured integrations. Attackers may use phishing or malware to breach supplier networks, then leverage these access points to target larger organizations downstream. These breaches are costly, with supply chain compromises accounting for a significant portion of recent incidents. By exploiting trust in third-party relationships, cybercriminals can cause widespread disruptions, data leaks, and financial losses across multiple sectors, emphasizing the need for rigorous supply chain security controls.

Credential Theft Prevalence

Credential theft remains a leading cause of data breaches in 2025, driven by cybercriminals exploiting weak or stolen login information. You might imagine hackers using various methods to access your accounts, such as:

  1. Phishing emails that trick you into revealing passwords or clicking malicious links.
  2. Brute-force attacks that systematically try multiple password combinations on vulnerable systems.
  3. Credential stuffing, where stolen username-password pairs are reused across different sites, gaining unauthorized access.

These tactics prey on human errors and security gaps, allowing cybercriminals to infiltrate networks easily. Once inside, they can escalate privileges, access sensitive data, or deploy malware. The prevalence of credential theft underscores the importance of strong, unique passwords and multi-factor authentication to protect your digital assets.

Types of Data Most Frequently Compromised
