Broadly understood cybercrime has been the biggest threat to organizations for years, representing a constantly evolving challenge that demands continuous vigilance. The vast majority of companies believe that individual hackers are the most dangerous, though this perception may underestimate the sophistication of modern threat actors.
Year after year, there is a growing threat that organizations see in dissatisfied or bribed employees. Insider threats pose unique challenges because these individuals have legitimate access to systems and often possess detailed knowledge of security measures and valuable data locations. Detecting malicious insider activity requires different tools and approaches than defending against external attackers.
Nearly half of companies are also concerned about organized cybercriminal groups and cyberterrorists. These sophisticated threat actors often have substantial resources, advanced technical capabilities, and the patience to conduct prolonged campaigns against high-value targets. Organized crime groups have professionalized their operations, employing developers, project managers, and even customer service representatives for their ransomware operations.
Understanding the primary attack vectors helps organizations prioritize their defenses. Phishing remains the most common initial access method, with attackers crafting increasingly convincing messages that exploit current events, business processes, and human psychology. Exploitation of public-facing applications, particularly unpatched vulnerabilities, provides another frequent entry point. Supply chain attacks have emerged as a significant concern, allowing attackers to compromise multiple organizations through a single trusted vendor.
Ransomware continues to dominate headlines and incident response efforts. Modern ransomware operations employ double extortion tactics, stealing data before encryption and threatening public release to increase payment pressure. Some groups have evolved to triple extortion, adding DDoS attacks or contacting victims’ customers directly.
It is also worth noting that this year nearly one in ten people had difficulty identifying groups that pose a real threat to the company. This uncertainty underscores the need for comprehensive threat intelligence programs that help organizations understand their specific risk profile and the adversaries most likely to target them.
Effective defense requires a multi-layered approach combining technical controls, employee awareness training, incident response capabilities, and regular security assessments to identify and address vulnerabilities before attackers can exploit them.

Frequently asked questions
What are the biggest cyber threats facing organizations today?
The most significant cyber threats include ransomware attacks that encrypt critical data and demand payment for recovery, phishing and social engineering campaigns that compromise credentials and deliver malware, supply chain attacks that leverage trusted software vendors to reach multiple targets simultaneously, and advanced persistent threats from nation-state actors that conduct long-term, stealthy espionage. Insider threats from malicious or negligent employees also represent a persistent and often underestimated risk to organizations of all sizes.
Why do so many organizations fail to detect cyberattacks that are already in progress?
Many organizations lack continuous security monitoring that can detect the subtle indicators of compromise that advanced attacks exhibit during their reconnaissance and lateral movement phases. Attackers often blend into normal network traffic and use legitimate administrative tools to avoid triggering signature-based detection. Without behavioral analysis capabilities and 24/7 monitoring, many intrusions go undetected for months, giving attackers ample time to establish persistence, steal data, and prepare destructive payloads.
How do cybercriminals choose their targets among organizations of different sizes?
Attackers use a combination of opportunistic targeting based on known vulnerabilities in common software and strategic targeting based on the value of the organization's data or infrastructure. Large enterprises are targeted for high-value intellectual property and financial assets, while small and medium businesses are targeted for their often weaker defenses and as stepping stones to larger partners and clients in supply chain attacks. No organization is too small to be targeted, and many attackers now use automated tools that scan the entire internet for vulnerable systems regardless of the victim's size.
What defensive capabilities are most effective against the biggest current cyber threats?
The most effective defenses combine technical controls with human capabilities and processes. Technically, organizations need endpoint detection and response, network monitoring, email security, vulnerability management, and tested backup systems. Human capabilities include security awareness training for all staff, a trained and practiced incident response team, and relationships with external security partners who can provide expertise during complex incidents. Regular penetration testing and tabletop exercises test and improve both technical controls and human response capabilities before real attacks occur.
