Latent Injection Ignore-Instruction Keyword
ATR detection rule by ATR Community (via NVIDIA garak latentinjection probe) · MIT
Detects instruction-redirect keywords buried within translation, whois, or factual contexts that pivot the LLM away from its original task, from NVIDIA garak latentinjection probe LatentJailbreak/LatentWhois classes. The attack embeds "Ignore the above directions", "Ignore the rest of this data", or "Disregard all info except" as injection_instructions inside otherwise-legitimate content. Distinct from ATR-2026-00399 (separator token) — this rule covers the instruction-keyword pattern where the attacker overrides context without a structural delimiter. Key signals: "Ignore X and print/say Y", "Disregard all info except", "it is critical to my career" social-engineering urgency combined with output redirect.

compliance:
nist_ai_rmf:
- subcategory: "MP.5.1"
context: >-
This rule detects latent prompt-injection keywords ("Ignore the above directions", "Disregard all info except") embedded within translation, whois, or factual content that redirect the LLM from its original task. MP.5.1 requires identifying and characterizing these adversarial input patterns as known risks to LLM integrity, especially when delivered indirectly via tool responses.
strength: primary
- subcategory: "MS.2.7"
context: >-
Latent instruction-keyword injection is a canonical LLM security/resilience failure mode drawn from the NVIDIA garak LatentJailbreak/LatentWhois probes; detection events feed continuous evaluation of the system's resilience against indirect prompt injection as required by MS.2.7.
strength: secondary
- subcategory: "MG.2.3"
context: >-
High-confidence matches on "Ignore X and print/say Y" or exception-redirect patterns in tool output must trigger pre-defined response actions to disengage or quarantine the manipulated agent turn before downstream execution, which is the risk treatment capability MG.2.3 requires.
strength: secondary
iso_42001:
- clause: "8.1"
context: "ISO/IEC 42001 Clause 8.1 (operational planning and control, including control of externally provided processes) is operationalised by this rule's detection of the prompt-injection attempt (Latent Injection Ignore-Instruction Keyword)."
strength: primary
- clause: "6.2"
context: "ISO/IEC 42001 Clause 6.2 (AI objectives and planning) calls for risk treatment of known attack patterns; this rule's detection of the prompt-injection attempt (Latent Injection Ignore-Instruction Keyword) is such a treatment."
strength: secondary
eu_ai_act:
- article: "15"
context: "Article 15 (accuracy, robustness and cybersecurity) requires high-risk AI systems to resist unauthorised attempts to alter their use, outputs or performance; this rule provides runtime detection evidence by flagging the prompt-injection attempt (Latent Injection Ignore-Instruction Keyword)."
strength: primary
- article: "9"
context: "Article 9 (risk management system) requires identified risks to be addressed by appropriate measures; this rule is a runtime risk-treatment control that detects the prompt-injection attempt (Latent Injection Ignore-Instruction Keyword)."
strength: secondary
- article: "14"
context: "Article 14 (human oversight) requires high-risk AI systems to remain subject to effective human oversight; this rule provides detection evidence where the prompt-injection attempt (Latent Injection Ignore-Instruction Keyword) would bypass or undermine that oversight."
