AIOpsDoom: subverting LLM-driven AIOps via telemetry manipulation¶

Scope: the first security analysis of LLM-driven AIOps (arXiv:2508.06394, RSA Conference 2025 / USENIX Security 2026), covering AIOpsDoom, an automated attack that injects "adversarial reward-hacking" payloads into telemetry to steer AIOps agents into malicious remediations, and AIOpsShield, the paper's telemetry-sanitization defense. Read alongside AIOpsLab, the benchmark this paper attacks against; the general agent security threat model (the lethal trifecta this attack instantiates in a new domain); the prompt-injection defenses shown here to fail against telemetry-borne payloads; and the field view of agentic AIOps deployments this threat applies to.

The AIOpsShield code block below (setup-phase taint identification, runtime field abstraction, an anchored-suffix evasion attempt) is an independent Python model written for this page and executed here; it is not the paper's own code, since AIOpsShield has no public release. Every number elsewhere on this page is quoted or aggregated from arXiv:2508.06394v2 (27 Aug 2025); the per-application and per-remediation aggregates, computed by summing Table 1's raw success counts, are given as prose in the results footnote below rather than as a separate table (cross-checked: they reproduce the paper's own stated 90% overall, 82% HotelReservation, and 82.2% Flash+GPT-4.1 figures exactly). RCA content on this page (e.g. the nginx-version example under "Agents make the lie more convincing on their own") is paraphrased from the paper's Section 3.5, not quoted as a verbatim transcript. As of 2026-07-16: AIOpsDoom's code is public and matches the paper's description (github.com/RSAC-Labs/AIOpsDoom, Apache-2.0, verified via the GitHub API: 4 stars, not archived, last updated 2026-06-26). AIOpsShield, which the paper says "will be released as open-source," has no public repository under RSAC-Labs or elsewhere that a GitHub search turns up; treat it as design-documented but not yet shippable.

What it is¶

AIOps systems automate anomaly detection, root-cause analysis (RCA), and remediation by having an LLM agent read telemetry (logs, metrics, traces) and either recommend or directly execute a fix. This paper is the first to ask what happens when the telemetry itself is adversarial, and answers that the whole pipeline is a viable attack surface: an attacker with zero privileged access and zero prior knowledge of the target's internals can pollute the telemetry an AIOps agent will later ingest, and reliably steer it toward a remediation that weakens the system.¹

Two artifacts implement this:

AIOpsDoom (AIOps payloaD lOg injectiOn Module) is the attack tool: a crawler enumerates the target's public endpoints, a fuzzer sends malformed requests (bad headers, cookies, params, non-existent paths) engineered to trigger error events, and an LLM-driven generator crafts the payload text that lands in the resulting telemetry.²
Adversarial reward-hacking is the payload design. Unlike classic prompt injection, which tries to override the agent's task, a reward-hacking payload stays consistent with the agent's actual goal (find the root cause, propose a fix) but plants a plausible-but-false cause (the lead) paired with an attacker-chosen fix (the body), optionally wrapped in a decorator string like [SOLUTION] $PAYLOAD to escape telemetry syntax and read as a hint left by a human.³

The threat model is deliberately weak in the attacker's favor: the target must (1) run an AIOps solution, (2) expose a public interface, and (3) let at least one telemetry instance incorporate externally-influenced data, which follows from (1) in practice. The attacker has no privileged access, no knowledge of which LLM or agent framework is deployed, and gathers everything else (server versions, plausible failure modes) through ordinary reconnaissance: port scans, crawling, OSINT.⁴

Why it matters¶

The attack works, and generic prompt injection does not. Across 180 trials (3 applications, 2 agent frameworks, 2 LLMs, 3 remediation objectives, 5 repeats each), AIOpsDoom's adversarial reward-hacking payloads achieved a 90.0% average attack success rate. The same telemetry-injection pipeline carrying ten standard prompt-injection triggers instead (Appendix A) scored 0%: 53.6% of the time the agent simply ignored the payload, and 42.9% of the time it explicitly flagged the telemetry as an attack.⁵⁶
It evades the defenses you'd reach for first. Against three prompt-injection detectors, adversarial reward-hacking payloads achieved a 100% evasion rate against Microsoft PromptShields and Meta's Prompt-Guard-2, and 85% evasion (15% recall) against the strongest of the three, DataSentinel. All three detectors had perfect precision on clean input; they simply never learned to see this payload class, because they are trained on unstructured jailbreak-style text, not telemetry syntax.⁷
A more capable model helps, but is not a defense. GPT-4.1 is measurably more resistant than GPT-4o, and Flash (which adds reasoning and hindsight over ReAct) is more resistant than plain ReAct, yet the single hardest configuration in the paper, Flash on GPT-4.1, still fell for the attack 82.2% of the time (37/45 trials).⁵
Agents make the lie more convincing on their own. In the paper's worked example, the agent fetched the real nginx version from the system and wove it into its RCA output alongside the attacker's fabricated cause, information that was never part of the payload. That self-added grounding makes the adversarial conclusion harder for a human reviewer or an LLM judge to catch.⁸
A telemetry-specific defense closes the gap cheaply. AIOpsShield, built from AIOps-specific structural properties rather than content classification, blocked every attack in the paper's re-run (0/180 successes) while a control study on 12 AIOpsLab tasks showed average agent success rate unchanged at roughly 50%, with one additional failed run out of 36 attributable, in the worst case, to the defense.⁹¹⁰

When to use it (and when not)¶

Use AIOpsDoom to red-team an AIOps deployment you own or are explicitly authorized to test, before it gets write access to production remediation. It is a genuine fuzzing/injection tool that deliberately drives real HTTP errors and alert conditions on the target; running it against a system you do not control or lack authorization for is the same category of action as any other unauthorized penetration test.
Use the adversarial reward-hacking payload design, not generic prompt-injection strings, when evaluating an AIOps agent's resilience: Appendix A's 0%-vs-90% gap means a red-team exercise built on off-the-shelf injection payloads will systematically under-report risk.
Use AIOpsShield's design (setup-phase taint analysis plus runtime field abstraction) as the reference architecture for a telemetry sanitizer, since there is no public library to install yet; the code block below is a from-scratch model of that design, not a wrapper around the paper's own implementation.
Do not treat this as a general prompt-injection benchmark. The attack and defense are both AIOps-specific: they lean on properties (structured, enumerable telemetry; limited legitimate role for user-supplied fields) that do not hold for open-ended RAG or chat applications, where user content is often exactly what the model needs to answer correctly.¹¹
Do not treat AIOpsShield as a complete defense even where it applies. It only closes the telemetry channel. An attacker who compromises the agent's toolbox, poisons a non-telemetry input, or attacks the supply chain is untouched by it, per the paper's own limitations discussion.¹⁴

The attack side (Section 3): reconnaissance builds the payload's context, the fuzzer's error-inducing requests turn that payload into stored telemetry, one of three activation modes (alert rule, ticket, or fixed schedule) gets the agent to read it, and the agent's own eagerness to solve the task does the rest. The defense side (Section 5) sits entirely on the telemetry read path: it is stood up once, offline, against the same crawl-and-fuzz surface the attacker would use, and then intercepts every telemetry read at runtime.

How to run AIOpsDoom¶

AIOpsDoom is a Python 3.11+ tool (crawler, fuzzer, and an LLM-backed adversarial reward-hacking payload generator) published under Apache-2.0.¹⁵ Installation, per the repository's README (reference commands, not executed here):

git clone https://github.com/RSAC-Labs/AIOpsDoom
cd AIOpsDoom
uv sync
uv run playwright install
uv pip install git+https://github.com/pasquini-dario/agentic_custom_lib@3c423bbf32ad8e4f7507e69efdeb1287481f9d49

# One LLM provider is required for AI-driven payload generation:
export OPENAI_API_KEY="..."          # or AZURE_OPENAI_API_KEY / AZURE_OPENAI_ENDPOINT
                                       # or run a local Ollama with no keys

uv run python aiopsdoom.py

The UnifiedCrawler drives an interactive Playwright session and records every HTTP request as you (or an agent) navigate the target, deduplicating by method, URL, parameters, and headers. The UnifiedFuzzer then injects the generated payload into every tamperable field of the discovered endpoints (query params, body fields, headers, cookies, paths), supporting both an "aggressive" mode (fuzz all fields at once) and a targeted mode (one field at a time), while leaving authentication tokens untouched.¹⁵ The ARHPayloadsGenerator implements the LLM pipeline from Appendix B: given a port-scan summary and the expected alert/error state, it produces a batch of grounded lead-plus-body payloads like the ten variants shown for the "open port 445" example in the paper's Figure B.1.¹⁶

Only run this against a system you own or are explicitly authorized to test. It exists to find the same weaknesses before an unauthorized attacker does, not to be one.

How to build a telemetry sanitizer (AIOpsShield's design)¶

AIOpsShield leans on three properties that hold for AIOps telemetry but not for general LLM inputs: the space of telemetry output is fixed and enumerable ahead of deployment; telemetry is structured (JSON or template-shaped text) and therefore parseable into fields; and user-supplied content carries little legitimate value for RCA, so untrusted fields can be abstracted away rather than merely flagged.¹¹

Setup phase (offline, before the agent goes live): reuse AIOpsDoom's own crawler and fuzzer, but fuzz with a unique canary string instead of a real payload, then pull every stored log, metric, and trace and look for that canary. Any field it lands in is untrusted by construction. For loosely structured entries, an LLM derives a regex per template; for strict JSON/traces, a schema is derived algorithmically instead. The regex-derivation prompt is run five times with five different random strings (not the literal canary) to generalize past the canary's specific character set, and a functionality loop re-feeds the LLM any regex that fails to actually extract the injected value until it converges.¹² On the three evaluated applications this setup phase produced 84 templates for SocialNet, 12 for HotelReservation, and 132 for AstronomyShop.⁹

Runtime phase: every telemetry read is matched against the template set; matched untrusted fields are replaced with a stable abstract token (USERNAME-1, USERNAME-2, ...), where the same raw value always maps to the same token, globally, across the whole session; everything outside an untrusted field passes through unchanged so the agent keeps the diagnostic signal it actually needs.¹³

The block below models both phases against the paper's own worked example for taint identification and template derivation: SocialNet's "user not registered" error log from Figure 9, a Thrift/RPC backend exception (TException/ServiceException), not an nginx/lua log; the paper's nginx/lua-formatted logs are a structurally different example shown in Figures 6b and 10, which this code does not model. It then goes one step further than the paper's own examples: it constructs an adversarial payload that embeds a fake copy of the template's own closing delimiter, to check whether an attacker can use it to smuggle text out of the untrusted-field boundary.

# aiopsshield_sanitizer.py - validated: models AIOpsShield's two-stage design
# (Section 5.1.1 setup phase / 5.1.2 runtime phase) on the paper's own worked
# example, the SocialNet "user not registered" Thrift/TException error log
# (Figure 9). This is a backend RPC exception log, not the nginx/lua-formatted
# logs shown elsewhere in the paper (Figures 6b, 10).
# Pure stdlib (re only). Demonstrates: (1) canary-based taint identification,
# (2) span-precise abstraction of untrusted fields with a globally-consistent
# scope, (3) that this neutralizes an adversarial reward-hacking payload
# regardless of its content, and (4) an anchored-suffix evasion attempt that
# tries to smuggle attacker text past the field boundary.

all AIOpsShield model assertions passed

Two things worth internalizing from this: first, sanitization does not depend on recognizing the payload as malicious, it abstracts the field unconditionally, which is exactly why the paper reports zero successful attacks rather than some detection-rate-dependent partial coverage.⁹ Second, an evasion attempt that tries to fake the field's own closing syntax does not escape the boundary here because the template's trailing anchor forces the regex to keep expanding the untrusted capture past the fake delimiter; whether that generalizes depends entirely on how tightly each derived template's boundary is anchored, which is exactly the setup-phase completeness argument the paper leans on.¹³

How to run it in production¶

Place the sanitizer between the telemetry store and whatever assembles the agent's context, not inside the agent's reasoning loop; the paper's design is explicitly transparent to the agent, and raw telemetry stays available to human operators for forensics even after the agent-facing copy is sanitized.¹³
Re-run the setup phase whenever the target application changes. Coverage is what the paper's residual-risk argument rests on: an injection point not seen during setup is not in the template set, and is therefore not sanitized at runtime.¹⁴
Do not stop at the telemetry boundary. AIOpsShield defends the specific vector this paper demonstrates. A compromised tool in the agent's toolbox, a poisoned non-telemetry input, or a supply-chain compromise bypasses it entirely; combine it with the sandboxing, allowlisting, and identity/intent controls in the general agent security threat model.
Gate destructive remediation behind confirmation regardless of defense posture. The paper's own numbers show a well-defended path can still fail (85% evasion even against the best of three commercial-grade detectors when no telemetry-specific sanitizer is present); treat automatic execution of PPA installs, version downgrades, or security-relevant config changes as the highest-risk action class, the same posture recommended for gating AIOpsLab-style agents before they get write access.
Budget for the fact that AIOpsShield itself is not installable today. As of 2026-07-16 only AIOpsDoom has a public repository; a production sanitizer built on this design is a reimplementation against Section 5.1's algorithm, not a dependency you can pin.

Failure modes¶

Pitfall	Cause	Fix
Generic prompt-injection filters miss the attack	ARH payload stays task-consistent; PromptShields/Prompt-Guard-2 are trained on unstructured jailbreak text, not telemetry syntax (100% evasion, Appendix D)⁷	Deploy telemetry-specific structural sanitization (AIOpsShield-style abstraction), not just a prompt-injection classifier.
Red-team exercises understate risk	Generic prompt-injection strings score 0% through the same injection pipeline that scores 90% with reward-hacking payloads (Appendix A)⁶	Red-team AIOps agents with reward-hacking-style payloads (plausible lead + contextual body), not off-the-shelf jailbreak strings.
"Smarter model" is treated as sufficient defense	Best-resistance combo (Flash + GPT-4.1) still falls for the attack 82.2% of the time (37/45 trials)⁵	Never rely on model capability alone; gate remediation execution behind policy or human approval.
Agent's own additions make the false RCA more convincing	Models fetch and append real system details (e.g. actual server version) to a fabricated root cause (Section 3.5)⁸	Treat agent-generated justifications as untrusted; verify remediation against ground truth before executing, not just plausibility.
Lower single-app attack rate is read as immunity	Fewer injectable telemetry fields lowers ASR (HotelReservation: 82%) but does not zero it, and the attacker needs only one success across repeated attempts⁵	Do not read a lower per-application ASR as safety; harden telemetry regardless of surface area.
Sanitizer coverage gaps go unnoticed	Setup-phase crawl and fuzz must be thorough; an injection point missed at setup is unprotected at runtime (Section 5.1.3)¹⁴	Re-run the setup phase on every application or endpoint change; version and audit the template set like any other security control.
Sanitizer treated as a complete defense	AIOpsShield only closes the telemetry channel; tool/supply-chain compromise and non-telemetry inputs bypass it entirely (Section 5.1.3)¹⁴	Pair with sandboxing and tool allowlisting from the agent security threat model; defense in depth, not a single control.
Assuming AIOpsShield is a library you can install	Paper states it "will be released as open-source," but only AIOpsDoom is publicly available as of 2026-07-16	Treat this page's code as a design reference to reimplement against Section 5.1, not a dependency to pin.
Running AIOpsDoom without authorization	It deliberately drives real HTTP errors and alert conditions on the target	Only run against systems you own or have explicit written authorization to test.

Abstract and Section 1 (arXiv:2508.06394v2): "we perform the first security analysis of AIOps solutions... adversaries can manipulate system telemetry to mislead AIOps agents into taking actions that compromise the integrity of the infrastructure they manage"; Section 3.1 threat-model conditions (1)-(3) on the target system; attacker has no privileged access and no prior knowledge of the AIOps internals, LLM, or configuration. ↩
Section 3.3.2 ("AIOpsDoom: Automated Telemetry Injection via Fuzzing") and Figure 3: two sequential components, the crawler (endpoint enumeration via captured HTTP traffic) and the fuzzer (systematic field-by-field payload injection, targeting error-inducing requests such as non-existent paths); worked example on SocialNet produced 120 requests resulting in 29 tainted telemetry instances (footnote 4). ↩
Section 3.4.1 ("Manipulation via Adversarial Reward-Hacking") and Figure 5: payload = lead (plausible incorrect root cause) + body (attacker's chosen remediation); Section 3.4.1 "More Contextual Relevance with Decorators" describes decorator strings ([SOLUTION] $PAYLOAD, #HUMAN HINT: $PAYLOAD) used to escape telemetry syntax and read as human-provided hints, with examples in Figure G.2; contrasted with classic prompt injection which overrides rather than steers the agent's objective. ↩
Section 3.1 ("Threat Model"): target conditions (1) uses AIOps, (2) has a public interface, (3) at least one telemetry instance incorporates externally-influenced information; attacker has no privileged access and no prior knowledge of internals, gathering only what reconnaissance (port scanning, OSINT, crawling) yields. ↩
Table 1 (per application/agent/LLM/remediation ASR and average rounds over 5 trials each) and Section 4.2 text: "the attack achieves an average success rate of 90% across all settings"; "even when using the Flash agent framework... combined with GPT-4.1, the agent still falls for most of the attacks, with an average success rate of 82.2%"; HotelReservation lowest at 82% because only URL-encoded traces are injectable there. Per-application and per-remediation aggregates on this page are computed by this page's author by summing Table 1's raw success counts (e.g. SocialNet 58/60=96.7%, AstronomyShop 55/60=91.7%, HotelReservation 49/60=81.7%; ⋆down 56/60=93.3% vs ⋆conf and ⋆PPA both 53/60=88.3%), and were cross-checked against the paper's own stated 90.0% overall and 82% HotelReservation figures, which they reproduce exactly. ↩↩↩↩
Appendix A ("Evaluate Baseline Attacks") and Figure A.1: ten standard prompt-injection triggers (Table A.1) run through the identical AIOpsDoom injection pipeline against SocialNet/GPT-4o/ReAct scored 0% attack success; outcome distribution 53.6% payload ignored, 42.9% malicious behavior detected, 3.6% rounds exhausted. ↩↩
Appendix D ("Evaluation of Prompt Injection Defenses") and Figure D.1: adversarial reward-hacking payloads achieved 100% evasion against PromptShields and Prompt-Guard-2, and 85% evasion (15% recall) against DataSentinel, the best-performing of the three; all three detectors had perfect precision on clean input. Section 5.1 attributes this to the semantic difference from classic injection (task-consistent, not task-overriding) and the domain shift from unstructured text (what the detectors were trained on) to telemetry syntax. ↩↩
Section 3.5 ("A Step-By-Step Attack on AIOps"), subsection "Legitimizing Payload with Agent-Added Content": the Flash/GPT-4o agent retrieved and included the real nginx distribution and version string ("openresty/1.15.8.1rc1"), information not present in the injected payload, alongside the fabricated root cause; additional examples in Table G.1. ↩↩
Section 5.1.3 ("On the Effectiveness of AIOpsShield"): setup phase produced 84 templates for SocialNet, 12 for HotelReservation, and 132 for AstronomyShop; re-running Section 4.2's attacks with AIOpsShield applied resulted in zero successful attacks, "every injected payload is sanitized by AIOpsShield before reaching the agent." ↩↩↩
Appendix F ("AIOpsShield's Impact on Utility") and Table F.1: 12 AIOpsLab tasks, Flash agent on GPT-4.1, 3 repeats each, with vs without AIOpsShield; both configurations average roughly 50% success rate, with AIOpsShield failing exactly one additional run (k8s_target_port-misconfig-detection-2: 2/3 without vs 1/3 with) out of 36 total runs, which the paper calls "statistically insignificant" even under the conservative assumption that the difference is caused by the defense rather than stochastic variance. ↩
Section 5.1: three properties enabling the defense (marked with suit glyphs in the paper): telemetry's output space is fixed and enumerable ahead of deployment (first property), telemetry is structured/parseable (second property), and user-supplied content has limited legitimate utility for RCA, verified empirically in Appendix F (third property). ↩↩
Section 5.1.1 ("AIOpsShield: Setup Phase") and Appendix E ("Regular expression derivation"): reuses the AIOpsDoom crawler/fuzzer with a unique canary string in place of a real payload; extracts telemetry containing the canary (including case-insensitive or base64-encoded variants); an LLM derives a regex (loosely structured entries) or algorithmic JSON schema (strictly structured entries) per template, with a robustness pass (regenerating the regex against 5 rounds of distinct random strings, not the literal canary) and a functionality feedback loop that re-prompts the LLM until the regex actually extracts the tainted value; Figure 9 shows the worked SocialNet example this page's code block reproduces. ↩
Section 5.1.2 ("AIOpsShield: Runtime Phase") and Figure 10: intercepts telemetry before the agent sees it, matches against setup-phase templates, and replaces untrusted parameters with abstract names that stay consistent for a given raw value both within and across runs ("Mozilla/5.0..." example maps to USERAGENT-42); sanitization is transparent to the agent and does not alter the raw telemetry retained for human operators. ↩↩↩
Section 5.1.3 ("Limitations and Generalizability of AIOpsShield"): defends only the telemetry-injection vector demonstrated in Section 3; cannot defend against an attacker who poisons other input channels or compromises the agent's toolbox/supply chain, and the paper recommends defense-in-depth for that stronger threat model; residual risk from incomplete setup-phase coverage is argued to be low given the defender's white-box information advantage over the attacker. ↩↩↩↩
AIOpsDoom README (github.com/RSAC-Labs/AIOpsDoom, retrieved 2026-07-16): Python 3.11+, uv sync plus Playwright browser install plus a pinned agentic_custom_lib dependency; UnifiedCrawler (Playwright/HAR-based endpoint discovery, signature-based deduplication) and UnifiedFuzzer (aggressive vs targeted field injection across params/body/headers/cookies/paths, session and auth-cookie support) match Sections 3.3.2 and Appendix H's description; repo confirmed public via the GitHub API (Apache-2.0 license, not archived, 4 stars); pushed_at on the default branch (commit ad0d256) is 2026-01-30, while GitHub's updated_at field, bumped by non-push events such as stars, is 2026-06-26; README also states the paper was accepted at USENIX Security 2026. ↩↩
Appendix B ("Automatic generating of adversarial reward-hacking payloads") and Figure B.1: GPT-4.1-based generator takes a port-scan result and an expected alert/telemetry-pollution state as input and produces a list of grounded lead-plus-body payload candidates; the ten-item "open port 445" example is quoted directly from Figure B.1. ↩
