Phishing in 2026 will be more complex and harder to detect as AI and advanced phishing techniques accelerate the threat landscape. In 2025 both the volume and technical sophistication of phishing attacks increased, and Barracuda’s Threat Analysis Team describes how these threats are expected to continue growing through 2026.
During 2025, phishing attacks advanced significantly, fueled by widely available AI-driven phishing services and sophisticated evasion techniques. This forecast from Barracuda’s Threat Analysis Team outlines how the threat environment will evolve as attackers become more technically skilled and better organized.
How phishing in 2026 builds on 2025 trends
Heading into 2025, analysts expected turnkey phishing kits to account for a large share of credential-stealing attacks. The outcome exceeded expectations: attackers quickly recognized the value of complete kits usable by both experienced and novice actors. The number of kits doubled during the year, further industrializing phishing. This sets the stage for 2026, when attackers increasingly adopt automated and context-aware techniques.
What to expect in 2026
2026 marks a clear shift as next-generation phishing kits begin to incorporate AI to build detailed target profiles. Attackers will rely more on automated methods to bypass protections like multi-factor authentication (MFA), for example by stealing tokens or relaying credentials through legitimate sites. New business models will emerge with subscription tiers ranging from basic packages to advanced AI-driven campaigns. By year-end, more than 90 percent of credential theft incidents are expected to originate from phishing kits, representing over 60 percent of global phishing attacks.
Dynamic, context-aware attacks
Attackers are moving from static playbooks to dynamic campaigns where language, links, content and payloads change based on user behavior, device or timing. These shifts make detection far more difficult. Techniques expected to rise in 2026 include steganography, where malicious code is hidden inside images or audio files; clipboard hijacking attacks that copy commands without the user noticing; wider use of shared and dynamic QR codes; continued abuse of OAuth; and increased use of blob URLs executed locally in browsers. Dynamic code injection and heavily obfuscated malware are also on the rise.
AI-driven, personalized campaigns
Generative AI enables highly convincing, personalized messages at scale, allowing attackers to rapidly pivot strategies based on recipient responses. These campaigns often combine encryption techniques to hide code and adaptable payloads. In 2026, more attacks will target AI-based security tools via prompt injection and attacks against AI agents.
Increased attacks on MFA and account recovery
Bypassing MFA remains a prominent trend. Attackers overwhelm users with push notifications until someone mistakenly approves a request. Social engineering is increasingly directed at password reset and account recovery processes, which are frequently easier to manipulate than the MFA systems themselves. Attackers also try to trick users into switching to weaker authentication methods that are easier to circumvent.
Attacks abusing CAPTCHA
By late 2026, over 85 percent of phishing attacks are expected to use CAPTCHA to create a sense of legitimacy. Attackers increasingly build fake CAPTCHA flows that mask the true intent of the attack, making it harder for users to recognize malicious activity.
More polymorphic techniques
Polymorphic attacks—where content and technical indicators change continuously for each user—are becoming more common. Random character strings, variable sender addresses, unusually long subject lines and altered filenames are used to evade signature-based defenses. In 2025 roughly 10 percent of phishing attacks leveraged legitimate services—a trend likely to persist as AI-driven, no-code platforms make it easy to create phishing sites in minutes.
Attacks exploiting URL protection and masking
In 2025 misuse of URL protection services, tracking links, redirects and convincingly legitimate URLs increased. These techniques appeared in about 25 percent of attacks and are expected to grow in 2026 as attackers become better at masking malicious links.
More advanced malware and fileless attacks
Malware is becoming more sophisticated with a strong rise in fileless attacks that live only in memory. Polymorphic payloads that change per target are becoming more common. Malware-as-a-service offerings continue to expand, lowering the barrier for new attackers to enter the field.
As we enter phishing in 2026, it’s clear organizations must take a more proactive stance to manage increased risks.
How to protect yourself as threats increase
Phishing is both more common and harder to detect, and this trend will continue in 2026. Recent surveys show a large percentage of organizations experienced email-related breaches in the past year. Traditional protections are no longer sufficient as attackers become more flexible and technically advanced. Reducing risk requires modern security solutions, continuous monitoring, robust authentication methods, layered defenses and a strong security culture.
