Kaspr's extension ID is on LinkedIn's AED detection list (Nov 2026 snapshot), and LinkedIn's page code checks for Kaspr on every visit by requesting chrome-extension://kkfgenjfpmoegefcckjklfjieepogfhg/assets/images/arrow.svg — a file that exists only if Kaspr is installed. Our code teardown rates Kaspr **HIGH risk**: Kaspr uploads your LinkedIn session cookie to the vendor's cloud (api.kaspr.io), so the vendor acts as you from another IP. Updated November 11, 2026 · LinkedIn AED snapshot Nov 2026 ID: kkfgenjfpmoegefcckjklfjieepogfhg ## Does LinkedIn detect Kaspr? What we found in its code Everything we confirmed in Kaspr's code, grouped by what it means for your account. Red = strongest detection / risk signals, amber = notable, grey = neutral or local-only. Detected by LinkedIn This browser extension is actively compiled into LinkedIn's frontend detection lists. LinkedIn's scripts can detect when this is active on your browser. LinkedIn requests: **chrome-extension://kkfgenjfpmoegefcckjklfjieepogfhg/assets/images/arrow.svg** DETECTED **What this means:** detection isn't an instant ban — it's one input to LinkedIn's risk _score_. But it's a standing signal: it stacks with your behavior (volume, programmatic clicks) and device fingerprint, and this is just the AED list — one of LinkedIn's three detection systems ([see how it works](https://browsergate.eu/how-it-works/)). We read Kaspr's code HIGH RISK Uploads your LinkedIn session to its cloud · on LinkedIn's detection list ### Kaspr's detection surface Signals LinkedIn's own page scripts can pick up directly on every visit — the extension probe (AED), code injected into the page (Spectroscopy), fake (isTrusted:false) clicks, blocked/missing telemetry, and cloud remote-control. Each adds points to its risk score.

If it uploads your session cookie to the vendor's cloud, the vendor can act as you from another IP — LinkedIn's loudest parallel-access tell. Reading the cookie locally (csrf/Voyager) is far less risky. session upload suspected reads li\_at harvests cookie jar ### Where Kaspr sends your data Every outbound destination found in the code — your session / scraped data, plus analytics, CRM pushes and CAPTCHA-solving services. LinkedIn can't see these, but it's where your data actually ends up. api.kaspr.io www.hubspot.com www.salesforce.com ### Permissions Kaspr requests Chrome permissions the extension was granted on install.

There's no 'authorize with LinkedIn' step anywhere. Simplified from its manifest — here's what actually happens between install and your first page load. linkedin.com Permissions granted on install: cookies activeTab scripting 3 permissions requested — no LinkedIn login involved Step 1 of 3 — Install ## Does Kaspr upload your LinkedIn session? Where your session and data actually go, reconstructed from Kaspr's code. Kaspr reads your li\_at cookie and uploads it — its cloud then acts as you, from its own IP. Sessions answering to this login right now: 1 → 2 red = your session/data leaving your machine · blue/green = stays local or only results leave · dashed = LinkedIn's own detection probes ℹ LinkedIn's own "where you're logged in" page does **not** gain a second entry from this — a replayed cookie isn't a new login, it's the same session answering from a second place. ### Does Kaspr run a parallel LinkedIn session from another network? LinkedIn doesn't need to know anything about proxies to catch this — it just needs one login cookie answering from two networks at the same time. Kaspr uploads your session cookie, so it can answer from its own network at the same time you're logged in from yours — one login, two places, at once. We actually measured this We measured real exit-IP reputation for 7 vendor clouds in a dedicated study — Kaspr's own infrastructure wasn't in that sample. The mechanism a session-upload creates is identical regardless: two networks, one cookie. ℹ Check LinkedIn's own "where you're logged in" page after playing this — it stays unchanged, because to LinkedIn a replayed cookie was never a new login. ## How we analysed Kaspr's code We downloaded Kaspr's published Chrome Web Store package, de-minified it, and read it file by file — **no live LinkedIn login**. Two ways to see how: Downloaded straight from the Chrome Web Store — the exact file your browser would install. 0/3 stages run [See the full method, step by step](https://safe-outreach.com/how-we-test) ## How LinkedIn fingerprints your browser while you use Kaspr Even after a cookie is copied out, LinkedIn keeps one more receipt on every request that follows — a 48-point snapshot of the exact machine making it. Faking it convincingly means reproducing that machine's quirks, not just editing a string. Click any signal above for what it means. These are illustrative values — this demo never reads your actual device. Your 48-point fingerprint — RSA-encrypted, attached to every API call in this session, not just login If this tool also uploads your session to another IP (see the data-flow section above), a cloud that never captured this exact fingerprint is highly likely to produce a mismatch on its very next request — server-side internals aren't observable from the code, so we hedge this as likely, not certain.

Our static code audit rates Kaspr HIGH risk. Its extension reads your LinkedIn session cookie and sends it to api.kaspr.io, so your account can be operated from another IP — one of LinkedIn's strongest ban signals, and its ID is on LinkedIn's detection list. No automation tool is ban-proof, and this one exposes a large detection surface. ### Does LinkedIn detect Kaspr? Yes. Kaspr's extension ID is on LinkedIn's active extension-detection (AED) list, so LinkedIn's page code probes for it on every visit (it requests the file assets/images/arrow.svg) — LinkedIn knows the extension is installed before you do anything. ### Can Kaspr get my LinkedIn account banned or restricted? Detection isn't an instant ban — LinkedIn scores accounts on many cumulative signals. But Kaspr stacks a known extension ID on LinkedIn's list, code injected into the page, programmatic (isTrusted:false) clicks, your session running from a foreign IP, and independent reviews report restrictions and permanent bans for Chrome-extension automators. Safe daily limits reduce the behavioral risk but can't offset a detectable architecture. ### Does Kaspr have access to my LinkedIn account? Yes. Its extension reads your li\_at session cookie and sends it to api.kaspr.io, so the vendor can act as your LinkedIn account from their own servers — even with your browser closed. ### How does Kaspr work — is it a Chrome extension or a cloud tool? Kaspr is a hybrid session-upload: the Chrome extension bridges your session to the vendor's cloud, which runs the automation server-side. ### What is a safer alternative to Kaspr? A standalone desktop app such as Linked Helper removes the two extension-specific detection surfaces: there is no Chrome-Store ID for LinkedIn's AED scanner to probe and nothing injected into the page for its DOM scan, and your session never leaves your machine. No tool is unbannable, but the surface it exposes is far smaller. --- Source: https://safe-outreach.com/is-kaspr-safe
