As of October 25, 2026 at 20:36, store.steampowered.com has a security score of 87.3/100 (grade B: “Good”). CyStack’s automated assessment recorded 10 issues to review after completing 100% of applicable checks. The website owner should address “Known-exploited CVE candidates” first, then review the remaining items in order of impact.
Does store.steampowered.com show known scam, phishing, or malware signals?
At assessment time, CyStack did not find store.steampowered.com or related infrastructure on any scam, phishing, or malware warning list after checking 5 online reputation sources. This result reflects external observations; it does not guarantee absolute safety or verify the organization’s legal status or reputation.
Potentially exposed domain email addressesChecks infostealer data for email addresses ending in @steampowered.com, the registered domain of the assessed website store.steampowered.com. A record is not counted merely because someone visited or signed in to the website.39 matching email exposure records

Frequently asked questions
What affects the security of store.steampowered.com?
A valid SSL certificate still does not prove that store.steampowered.com is safe, legitimate, or free of scam signals. For a more complete assessment, this report also checks phishing and malware, exposed email records, IPs and open ports, subdomains, technologies, and CVEs that may apply to observed versions.
Does store.steampowered.com use HTTPS, and is its SSL certificate valid?
store.steampowered.com used a valid SSL certificate at assessment time, valid until January 19, 2027. This status may change when the certificate expires or the server configuration changes.
Data compiled from CyStack cybersecurity monitoring systems
CyStack compiles scan results from its internal cybersecurity monitoring systems, including CyStack VulnScan and CyStack Threat Intelligence, together with publicly available Internet data. The assessment only observes and analyzes information already available; it does not attempt unauthorized access, test passwords, send exploit code, or change or disrupt the assessed system.
These 3 failed checks or warnings have the greatest impact on the result for store.steampowered.com.
Known-exploited CVE candidatesFound 1 known-exploited candidate(s), but the external product fingerprint requires verification.Critical
Why it matters
This check asks whether an applicable CVE candidate also appears in the CISA Known Exploited Vulnerabilities (KEV) catalog. A positive match means attackers have used that vulnerability in real incidents and warrants urgent investigation, but the installed software still needs to be confirmed as affected.
What to do
Verify the installed product immediately and follow the CISA and vendor instructions for mitigation, patching, or upgrading if it is affected.
Session cookies protected from scripts (HttpOnly)1 of 1 observed session-like cookie(s) on the inspected root response do not use HttpOnly.High
Why it matters
HttpOnly prevents browser scripts from directly reading a cookie. It does not fix script injection, but it makes theft of session and authentication cookies more difficult.
What to do
Set HttpOnly on session and authentication cookies unless the application has a documented need to read them in browser code.
Allowed browser content (CSP)The CSP on the inspected root HTML response contains a broad, unsafe, or missing script-source control recognized by this bounded check.High
Why it matters
Content Security Policy (CSP) limits where scripts, styles, frames, and other browser content may come from. A strong policy reduces the impact if an attacker manages to inject content into a page.
What to do
Define only the sources the application needs, test the policy before activating it, and avoid broad wildcard (*) rules, unsafe-inline, and unsafe-eval where possible.

This is a quick, point-in-time check from outside the organization. It can surface visible risks, but it does not replace penetration testing or an authenticated assessment.
Have @steampowered.com email addresses appeared in exposed data or information-stealer (infostealer) logs?
There are currently 39 exposed email records matching the steampowered.com domain. These records may be old or already resolved. The website owner should verify them before resetting passwords or locking related accounts.
Which public IPs, services, and ports does store.steampowered.com expose?
The assessment observed 1 public IPs and 2 open ports for store.steampowered.com; the infrastructure appears to be operated by Akamai Technologies, Inc.. An open port is not automatically a vulnerability, but every public service should be updated and appropriately restricted.
How many subdomains of steampowered.com have been discovered?
The assessment observed 169 public subdomains of steampowered.com. This list can reveal additional entry points such as APIs, administration systems, or test environments, but it does not mean that every subdomain is risky.
