EDR Evasion & Telemetry

edr-misclassification-and-blocking

Automation and runtime behaviors (PowerShell encoding/escaping, non-interactive host selection, named-pipe/DLL interactions, and added security descriptors) get misclassified by EDR, triggering alerts/blocks or forcing security changes that break apps while leaking identifiers via transcripts.

"Application failed to respond" — hosted on Railway. Tension: The Railway automatically assigns a dynamic port, and there is no need to write a hard-coded value. Outcome: erasing the port environmental variable from Railway.

such as the entry of a wrong password or wrong CSRF tokens. Tension: more an user error than a system error or caused by spam bots. Outcome: collect exception classes which are safe to ignore.

Failed to report an error on a session because there is none active. — on the Application Output. Tension: I see the manually captured error on my Sentry Dashboard. However I'm concerned about these warning messages.

I do not want to disable PowerShell monitoring entirely, nor globally allow AADInternals — in a hybrid environment using Azure AD Connect. Tension: Couldn’t find a way to trace or whitelist only that specific PowerShell import.

if your computer and device are connected to an unsecured or public network — enabling ADB over TCP/IP. Tension: anyone on the same network could try to connect to your device and gain unauthorized access. Outcome: the connected device is more vulnerable to unauthorized data access, command execution, or even malware installation.

I suspect this application might be sending my files to a remote server without permission — I'm using a Windows application (.exe) written in Python to manipulate files in a folder. Outcome: The application is supposed to be offline.

I want to be able to access this via all of the usual suspects (VBA, Interop, EPPlus, ClosedXML) and some unusual suspects (Dev Express) — My company recently implemented this as a requirement before saving a document. Outcome: That looks like a "Sensitivity Label" - mandatory by IT policy.

Adding nondeterministic compilation breaks reproducible builds — users will no longer be able to verify the packages they install. Tension: this security measure is a good example of so-called security theater. Outcome: it will not provide additional security for most of the cases, but will greatly complicate a lot of things.

it will likely result in a number of nondeterministic bugs — users of source-based distributions could take advantage of this security measure. Tension: which will be impossible to locate automatically. Outcome: will greatly complicate a lot of things.

trigger programs, check constraints, view definitions, etc. — if the new function has side effects or reveals internal state about the application and the -directonly option is not used. Tension: the application into running the function with parameters of the attacker's choosing. Outcome: Marking a function as direct only disqualifies it from being run in those situations.

As you only check the IP, this works and the attacker can now execute API calls against your application. — an attacker has control of a malicous site. Outcome: Defending against this requires authentication of the requests to the API.

An attacker finds a vulnerability in one of your frontend-dependencies which he is able to exploit somehow — the backend stack is highly secure. Tension: malicious behavior which effects your highly secure backend-application. Outcome: keep your front end packages up-to-date.

handling endpoint authentication of Entra to custom SCIM endpoint. Outcome: And I can't understand why this line was added.

issue has been reported to implement anti debugging protection for ios. Tension: I've not configured anything for anti debugging protection. Outcome: during penetration testing.

There is however a risk of another exploit, DLL Injection. — The service is a sort of privileged helper for the client to perform elevated tasks. Tension: If a DLL is injected into our client process, when the DLL tries to conn.

could be leaked in network connections by doing this.

a powershell window pop and close right away, than my antivirus (norton) alerted me — at random time on my day. Tension: Activity: An intrusion attempt by 172.64.142.7 was blocked. Outcome: Windows PowerShell transcript start.

The Heroku-hosted MERN app receives many automated-looking requests from the same forwarded IP in the same second, with suspicious query/path content (e.g., unexpected “if”/“php” strings). This behavior appears to be scanning or an attack proxy and raises concerns about security and abuse.

In the event that an attacker can dump the entire RAM (e.g. through DMA) — DPAPI on Windows provides functions to encrypt and decrypt arbitrary data. Tension: will DPAPI use it to protect its encryption key instead? If so, for which of the functions previously listed is this true?

I got nothing in the evt.etl file. Tension: Get-WinEvent : No events were found that match the specified selection criteria. Outcome: It turned out to be this provider is protected.

developers get confusing compile errors when trying to use System.IO, System.Reflection, System.Threading.Thread, System.Net, System.Diagnostics.Process, and other restricted APIs — In s&box, the .NET API is sandboxed. Tension: many standard .NET types and namespaces are blocked for security. Outcome: The whitelist is enforced at compile time.

generic 'error' instead of actual error messages — MCP tool error traces in production. Tension: making debugging impossible.

shell metacharacters in outname (`;`, backticks, $(), `|`) execute arbitrary commands — when an attacker-controlled patch file is processed. Outcome: CVE-2018-1000156's get_ed_command_letter() filter only constrained which ed commands were forwarded; it did NOT sanitize the filename interpolated into popen.

suffers an unbounded memory allocation (DoS) — when processing a crafted ELF file.

Agents ignore multi-step workflows in server instructions 40%+ of the time — MCP tool activation across coding agents [redacted:name] VS Code Copilot, Cursor, Codex. Tension: Need cross-platform lifecycle hooks to enforce behavior like "search before debugging" and "contribute after solving.". Outcome: all four major platforms now support them, but with different formats, file locations, and event sets.

Tension: attacker-controlled sizes from PAX extended headers. Outcome: triggering a SIGSEGV/stack exhaustion.

resulting in a write to freed heap memory via memset() — during the TLS handshake. Tension: If key derivation fails during client key exchange processing, the ephemeral parameters are freed by calc_ecdh_key() but then accessed again by the caller's cleanup code. Outcome: The vulnerability is fixed by eliminating the double-cleanup anti-pattern.

requested crawler-facing e2e coverage — for discovery documents, anonymous MCP access, registration, onboarding, and authenticated MCP flows. Tension: A collaborator also requested. Outcome: crawler-facing e2e coverage for discovery documents, anonymous MCP access, registration, onboarding, and authenticated MCP flows.

Long-session continuity tests also produced false failures — when ACK tokens appeared in the user's own prompt or were altered by Markdown rendering. Tension: ACK tokens appeared in the user's own prompt or were altered by Markdown rendering. Outcome: Use Markdown-safe alphanumeric ACK markers, wait specifically for an assistant-role ACK before navigating away, and classify browser events into fatal, expected fresh-auth noise, unexpected browser errors, journal failures, and journal warnings.

An ETL pipeline slowed from 19s/pair to 40-47s/pair — after one "resilience hardening" commit changed three perf-relevant knobs at once. Tension: TWO commits 15 minutes apart each claimed to be "the actual cause" of the SAME slowdown, with no measurement between them. Outcome: the file documented a policy it did not implement, and nobody could tell whether the regression had returned.
