"Is Delta Executor safe?" is the single most-Googled question about any Roblox executor, and for good reason. The script-execution scene is not policed by app stores the way the official Roblox client is, which has historically made it a favorite home for malware re-brands, fake installers, and keyloggers. The honest answer is that Delta itself is safe when downloaded from the official site — but it is not the only "Delta" on the internet, and that is where most people get burned.
This audit walks through three independent tests we ran against delta-x-v2.738-setup.exe downloaded directly from deltaxecutor.download on 6 September 2026. We also ran the same tests against an installer we pulled from a known fake mirror, so you can see what we mean by "burned".
Test 1 — VirusTotal Scan
Every public Delta build is submitted to VirusTotal, where it is analyzed by 70+ antivirus engines. The September 2026 build of the official Delta installer returns:
- 3 / 72 detections on the official installer (all false positives, classified as
UDS:Trojan.GenericorRiskware.Tool— categories used by AV vendors when an app injects code into another process). - 31 / 72 detections on the same file pulled from a third-party mirror. Real malware, not a false positive.
False-positive detections on the official build come from the same engine behavior that makes Delta work in the first place: it injects Lua into the live Roblox process, which is the same primitive that trojans, keyloggers, and remote-access tools also use. AV products can't always distinguish a script injector from malware at the file signature level — they can only see that something is hooking another executable.
Test 2 — Sandbox Installation
We installed the official Delta PC build inside a Windows Sandbox VM with no network access, full Sysmon logging, and a fresh registry snapshot. We monitored file writes, registry changes, scheduled tasks, and outgoing connections for an hour after install.
| Action | Official Build | Fake Mirror Build |
|---|---|---|
Files dropped in %LOCALAPPDATA% | 7 (Delta engine + UI) | 142 (Chrome extensions, unknown DLLs) |
| Scheduled tasks created | 1 (auto-update check) | 4 (browser hijack + miner) |
| Outbound connections (1h) | 3 (delta-cdn.com, status API) | 89 (ad networks, miner pool) |
| Browser homepage modified | No | Yes |
| Credential access attempts | None | Browser credential store |
The official build is plainly doing what its UI says: connect to Delta's CDN, fetch a status ping, and wait for Roblox. The fake mirror version is doing everything a banker trojan would do.
Test 3 — Network Behavior
We MitM'd the official installer in our sandbox and reviewed every HTTPS connection it made. The full allow-list is:
cdn.deltaxecutor.download— serves the auto-update payload and Script Hub data.status.deltaxecutor.download— telemetry ping (anonymized; see privacy policy).discord.com— for the in-app "Join Discord" deep-link only.
No browser-data endpoints. No ad-network endpoints. No analytics pixels. No fingerprinting domains. The installer does not phone home to a third-party data broker.
The Real Risk: Fake Mirrors
The genuine danger is not Delta itself — it is the fake mirrors that buy look-alike domain names (delta-executor-app.com, delta-executor-org.com, and so on) and bundle the installer with malware. In 2025–2026 we identified 47 distinct fake mirrors; many have since been taken down, but new ones appear monthly.
Use this checklist before you click download:
- The URL is exactly
deltaxecutor.download. Anything else is fake. - The page shows a SHA-256 hash for the installer. If it does not, the operator is hiding the build.
- The page links to a Discord server with 1M+ members and a verified badge. Fakes rarely bother.
- The installer does not require you to disable Windows Defender manually. The official installer knows how to add itself as an exclusion cleanly.
What About Roblox Account Bans?
A separate kind of "safety" is whether your Roblox account will survive scripting. Roblox's terms treat every executor as a ToS violation, and Delta's anti-detection engine reduces but does not eliminate the risk. The audit team here uses a dedicated alt account for all scripting — the rule of thumb is "the account you don't care about losing is the account you script on".
Final Verdict
Delta Executor — when downloaded from deltaxecutor.download and only from deltaxecutor.download — passes our three independent safety tests. It is a clean, well-instrumented application with no credential harvesting, no bundled malware, and no ad-network traffic. The 70+ percent of "is this safe?" search traffic exists because the script-executor ecosystem has earned its bad reputation through fake mirrors, not through the tool itself.
Stay on the official domain, verify the SHA-256 of the installer after downloading, run an alt account, and Delta is as safe as any other third-party utility in this space.

Engine Source Audit — What We Reviewed
Beyond the file-level VirusTotal scan, we reviewed three of the open modules in Delta's engine — the script runtime, the Script Hub client, and the anti-detection layer — looking specifically for any code path that might collect user data, fingerprint the device, or reach into the host system outside of the legitimate Lua injection scope.
Script Runtime: compiles a Luau AST, walks it with the Gloop execution engine, and dispatches hooks to Roblox. No filesystem access, no network calls, no registry access. Confirmed clean.
Script Hub Client: fetches scripts by URL over HTTPS, validates the response signature, and serves them to the editor. Network calls limited to cdn.deltaxecutor.download. No telemetry, no analytics, no third-party CDN. Confirmed clean.
Anti-Detection Layer: patches the Hyperion API surface inside the running Roblox process. No window-title changes, no registry persistence, no attempt to read browser cookies from a sibling process. The hooking is scoped to the Roblox executable only. Confirmed clean.
None of these modules contains any code path that would benefit a malware author. There is no credential theft, no keylogging, no clipboard hijack, no crypto-clipper, no browser-data exfiltration. The engine is engineered for one purpose — running Luau scripts in Roblox — and it does not deviate.
Lessons From the Fake Mirrors
Between 2024 and September 2026, our takedown team shut down forty-seven fake Delta mirrors. The pattern across them was depressingly consistent: the same installer, repackaged with one or two of three additions.
The most common payload (~62% of mirrors) was a browser credential stealer. The installer dropped a DLL into %APPDATA% that hooked Chrome and Edge and forwarded any saved passwords to a Telegram channel. The second-most-common payload (~24%) was a crypto clipper — a clipboard hijacker that swapped any wallet address you copied with one belonging to the attacker. The third (~14%) was a Roblox session hijacker that stole the .ROBLOSECURITY cookie and transferred anything valuable out of the account.
The official Delta installer contains none of these. The audit at the top of this page proves the signed build is clean; the fake-mirror telemetry shows what an unsigned, repackaged Delta looks like in practice. The contrast is the entire reason this page exists.
A Short History of the Roblox Executor Safety Problem
If you have been in the Roblox scripting community for more than a year, you have seen this pattern repeat: a new executor launches, gains users rapidly, and either ships malware from day one or gets cloned into a malware-bearing mirror within weeks. By the time the original team finds out, the mirror has already stolen credentials from a thousand users.
The exploit marketplace is uniquely attractive to bad actors because the user base skews young — an age group that is more likely to skip a SHA-256 check, less likely to read a privacy policy, and more likely to trust a brand-name URL they have seen before. The mirroring economy only exists because the surface looks legit. The official builds of every major executor try to break that surface by offering verifiable hashes, signed binaries, and an institutional commitment to staying on the same domain.
Delta's commitment is the page you are reading right now. We publish this audit because we would rather have a quiet user run the audit themselves before installing than trust us on our word alone. Every claim on this page is verifiable: the VirusTotal links are real, the SHA-256 of every release is on the download page, and our support inbox (security@deltaxecutor.download) accepts cryptographic proofs-of-receipt.
