Using an unordered list, summarize the following article with between 4 and 8 key points.
\n\t\t\t\t\tThere are four critical and unpredictable threats where attackers hold a significant advantage to successfully exploit weaknesses in targeted organisations, according to Gartner.
\nThese include deepfakes, AI application compromise, prompt injection, and software supply chains.
\nThe Gartner ThreatScape categorises the threats into six distinct areas along two axes:<\/p>\n

Differentiating threats based on the quality and volume of information (\u201cthreat signal\u201d) available.
\nAssessing threats based on organisational capabilities to manage them, and whether the threat actors hold an advantage.<\/p>\n

\nThe Gartner 2026-2027 ThreatScape
\nSource: Gartner (June 2026)
\n\u201cThe introduction of security initiatives by frontier AI companies creates significant noise to an already noisy threat landscape,\u201d says John Watts, VP analyst at Gartner. \u201cCybersecurity leaders must be able to find the threat signal in all the noise in order to respond to shifts in the threat landscape.\u201d
\nWatts explains how CISOs can tackle these four critical threats:
\n\u00a0
\nAI application compromise
\nAI application compromise is in the critical threat section as attackers target the growing number of production-ready public-facing and internal enterprise AI tools. The attack surface has grown to include custom-built agents, third-party integrations, and employee-only applications often exposing sensitive data or credentials when controls are weak.
\n\u201cCybersecurity teams need to expand their programmes beyond traditional software protections by mapping new attack surfaces introduced by GenAI models or agentic tools,\u201d says Watts. \u201cUsing Gartner\u2019s trust and risk in security management (TRiSM) framework allows cybersecurity teams to know where to embed AI-specific threat mitigations directly into the AI application development process.\u201d
\nSecuring an AI application does not always mean starting from scratch. There are many AI security startups that offer broader and deeper capabilities as organisations mature and need more security around their use of AI. To address this threat, CISOs should apply secure development life cycle and threat modeling best practices to AI applications. They should also strengthen data security by improving data classification, adopt purpose-based access control (PBAC), and implement runtime monitoring.
\n\u00a0
\nIdentity impersonation using deepfakes
\nThe advent of GenAI has dramatically increased the volume, fidelity and accessibility of deepfake creation across voice, video and images, both as pre-recorded artifacts or generated in realtime. This has expanded the opportunity for attackers to impersonate identities across a range of attack surfaces. Deepfakes can be used to attack biometric authentication processes, can be combined with social engineering in realtime attacks on employees, and can be used to subvert recruitment processes.
\n\u201cAttacker use of deepfakes continues to advance and is now commonplace to make fraud and phishing scams difficult to detect,\u201d says Watts. \u201cThere is no one cybersecurity control that will protect you. Instead, organisations should use a combination of strengthening business processes, improving awareness, and deploying available deepfake detection technologies where possible.\u201d
\nAs a result, cybersecurity teams must look beyond deepfake detection and strengthen controls to protect the integrity of realtime communications, as well as biometric authentication and verification processes by considering the following:<\/p>\n

Build a robust mitigation strategy by recognising that deepfake detection alone is not sufficient to detect and prevent deepfake identity impersonation attacks. Instead, focus on layers of controls that will vary by use case.
\nProtect biometric identity verification by focusing on presentation and injection attack detection in addition to contextual signals.
\nSecure online meetings by implementing conditional access policies to enforce strong authentication for call participants and analysis of call metadata.<\/p>\n

\u00a0
\nSoftware supply chain threats
\n\u201cThe evolution of GenAI offerings will only accelerate the trend of software supply chain attacks through vulnerabilities in open source software,\u201d says Watts. \u201cOrganisations must work towards trusted component registries, hardening their CI\/CD pipelines, and building strong operational anomaly detection and response capabilities.\u201d
\nCybersecurity teams should build comprehensive inventories of software assets while integrating strong controls at every stage of development. These measures help defend against emerging threats that target both traditional applications and modern AI-powered pipelines. With this in mind, CISOs should:<\/p>\n

Require SBOMs (and AIBOMs) from all vendors; assess every component for risk using tools with up-to-date threat intelligence before deployment.
\nUse curated repositories for third-party code, container images and AI models; enforce branch protection on code repositories.
\nSign artifacts during builds; implement least-privilege access controls on build systems; continuously monitor runtime activity by agentic tools.<\/p>\n

\u00a0
\nPrompt injection
\nPrompt injection is a cybersecurity threat targeting AI systems, especially those using large language models (LLMs). Attackers manipulate prompts to alter the model\u2019s behaviour, causing it to leak sensitive information, perform unauthorised actions, or bypass controls. As organisations increasingly adopt GenAI, the risk of prompt injection expands, making it a critical issue for cybersecurity teams.
\nTo effectively counter prompt injection threats, cybersecurity teams should implement a layered mitigation strategy. This involves AI security testing to proactively identify vulnerabilities, establishing strong system prompts to guide AI behaviour, and deploying AI runtime guardrails that monitor for and block suspicious activity. Key actions for CISOs include:<\/p>\n

Implement input validation and sanitisation to filter out potentially malicious prompts.
\nEstablish monitoring and alerting for abnormal AI behaviour that may indicate successful prompt injection.
\nIntegrate prompt injection testing into the AI system development lifecycle.
\nLeverage the outcomes of the testing to improve runtime controls.<\/p>\n
