Cybersecurity for gaming, tested from the game client to the wallet

Game studios and platforms hold player accounts, virtual currency and payments that attackers and cheaters target. ioSENTRIX tests your game client, servers, APIs, wallets and people the way an attacker would, and a retest of your fixes is included.

01The short answer

What does cybersecurity for gaming involve?

Protecting player accounts, in-game economies and payments across every surface a player or an attacker can reach: the game client, game servers and APIs, wallets and stores, payment flows, consoles and devices, and staff. For many studios it also means evidence for PCI DSS, privacy laws and, for games directed to children, COPPA.

The targetAccounts and virtual value

Attackers want player accounts, virtual currency and items they can sell or trade.

The methodClient and server, together

Testers modify the client and replay its traffic to find what the server trusts that it should not.

The proofProof of concept and a fix

Every finding comes with a proof-of-concept exploit and a prioritized recommendation.

Why is cybersecurity in gaming different?

Games run code on players' own devices, so the client cannot be trusted, and in-game items and currency have real value. Read top challenges in gaming cybersecurity.

What is game security testing?

Game security testing is an authorized, simulated attack on a game and its back end: the client and its anti-cheat protections, game servers and APIs, accounts, wallets and payments. It shows what a cheater or attacker could reach and proves the impact.

02See it in action

One attack path from a modified client to the in-game economy, proven then fixed

Anti-cheat and server checks are often reviewed separately. Cheaters chain them. This is how one path from a modified game client to traded items is found, proven and closed.

Client and server, together

We test the client and the server as one system, so a cheat that only works because the server trusts the client is found.

Impact in player terms

Findings are proven on agreed test accounts and described as what a cheater or attacker could gain, not as a scanner score.

Closed, then proven closed

Each step gets its own fix, and the whole path is replayed in the retest to show it no longer works.

Illustrative example. The game, endpoints, path and statuses are a composite for explanation only and do not describe any client. Testing uses builds, accounts and environments agreed in the rules of engagement.

Text version of the exhibit

Recon: testers patch a test build of the game client so it sends crafted match results.
Pivot: the game API accepts the score and rewards exactly as the client sends them.
Wallet: replaying the result credits soft currency to the test wallet without limit.
Trade: items bought with the credited currency can be traded to a second test account (unrestricted access to sensitive business flows, OWASP API Security Top 10 2023, API6). The chained finding is rated Critical.
Fixed: four fixes, one per step: client integrity checks, server-side validation of results, idempotent and capped rewards, and holds and checks on trades.
Retested: the full path is replayed and refused at the first check. Studio evidence: proven economy abuse, fix owners and retest results.

04Regulation

Which rules call for security testing at gaming companies?

The rules game studios are asked about most often, and what each one says about testing.

PCI DSS v4.0.1

Requirement 11.4

Applies to

Studios and platforms that store, process or transmit cardholder data

What it says about testing

Internal and external penetration testing at least once every 12 months and after significant changes (11.4.2, 11.4.3); segmentation tests every 12 months, or every six months for service providers (11.4.5, 11.4.6). PCI SSC ↗

COPPA Rule

16 CFR 312.8

Applies to

Operators of services directed to children under 13, or that knowingly collect their personal information

What it says about testing

A written information security program that includes risk assessments at least annually and regular testing and monitoring of the effectiveness of its safeguards (312.8(b)). eCFR ↗

GDPR

Article 32(1)(d)

Applies to

Controllers and processors within the GDPR's territorial scope (Article 3)

What it says about testing

Appropriate technical and organisational measures including, as appropriate, a process for regularly testing, assessing and evaluating their effectiveness. EUR-Lex ↗

Orientation, not legal advice. Which rules apply depends on your players, where you operate and how you take payments. ioSENTRIX is not a PCI Approved Scanning Vendor (ASV) or Qualified Security Assessor (QSA): we perform the penetration testing and write reports your QSA or auditor can review.

09FAQ

Gaming security questions

Short answers to what studio security and engineering leads ask us most.

Ask us something else

What are the biggest cybersecurity threats in gaming?

Common threats include account takeover, client tampering and cheats, abuse of game APIs, virtual currency and wallet fraud, payment abuse, DDoS attacks on game servers, flaws in console and device firmware, and phishing of staff. Each targets player accounts, in-game value or availability, and each needs a different test.

Can you test our anti-cheat?

Yes. We test the game client and its protections the way a cheat developer would, in an agreed test environment: modifying memory and files, tampering with traffic and replaying requests, to find what the server trusts that it should not. We report how the protections were bypassed and which server-side checks would stop it. We do not build anti-cheat systems.

Do you provide DDoS protection?

No. ioSENTRIX does not provide DDoS mitigation. We assess how exposed your game servers, matchmaking and APIs are, including rate limits and resource-heavy requests (API4 in the OWASP API Security Top 10 2023), so you can decide where protection is needed.

Does COPPA require security testing?

The COPPA Rule at 16 CFR 312.8 requires covered operators to keep a written information security program that includes risk assessments at least annually and regular testing and monitoring of the effectiveness of its safeguards. A penetration test is one way to evidence that testing. Whether COPPA applies depends on your audience, so confirm it with your counsel.

How do you test virtual currency and in-game economies?

We act as several test players and change amounts, item IDs, timing and the order of requests to find duplication, replay, race conditions and limit bypasses in rewards, stores, trades and wallets. Each finding is proven on test accounts and mapped to the OWASP API Security Top 10 (2023).

Do you test consoles and gaming devices?

Yes. We test console, handheld and peripheral firmware and the services they talk to. See embedded device penetration testing.

How long does a game security test take?

A web application or API penetration test typically takes 1–2 weeks and a red team exercise typically 4–6 weeks, depending on scope. You receive a written scope and timeline before testing starts, so you can plan around launches and live events.
