A Device Security Checklist for Poker Players: Don’t Let the Cheating Happen on Your Side

Fairness debates focus on platforms — but a whole class of risk lives on your own device. The platform’s cryptography can be flawless; if someone is watching your screen in real time, your hole cards are face-up. This is a device security checklist written for regular players.

The four typical player-side attacks

• Screen grabbing: malware or “remote assistance” software streams your screen to an attacker — no encryption to break, they simply watch your cards. Such malware is commonly bundled inside “poker helper tools” and “equity calculators”
• Malicious browser extensions: extensions can read page content; one disguised as a “hand history assistant” sees everything rendered on the page
• Clipboard and input hijacking: stealing copied usernames, passwords, and recovery phrases
• Fake clients and phishing sites: look-alike domains and interfaces that harvest your login, or hand you a modified client outright

Note the common thread: none of these needs to defeat the platform. They attack you.

The practical protection checklist

• Never install “poker helper software” of unknown origin — the number-one source of player-side infections, and buying such tools is usually cheating anyway
• Audit browser extensions regularly; keep only essentials in the browser you play in — or use a dedicated browser profile just for poker
• Check the domain before logging in: bookmark the correct address, always enter via the bookmark, never click “promo links” from group chats
• Never run remote-assistance or screen-sharing software while playing; streamers must mask the hole-card area and add delay
• Keep system and browser updated; use a long, unique password not reused anywhere else
• Never log into a poker account on public computers or open WiFi; lock the screen when you step away

What the platform side can do for you

Good architecture minimizes the blast radius of a compromised device. Fair Poker, for example: the account key vault is stored locally, encrypted with your password — the server holds no plaintext; hole-card decryption material exists on your machine only for the duration of the current hand and is wiped when it ends — so even a later intrusion finds no historical card material. Of course, no platform can defend a screen being watched during a live hand; the checklist above is your first line of defense.
