Is the website “uptodown.com” safe?
As of September 3, 2026 at 14:42, uptodown.com has a security score of 89.1/100 (grade B: “Good”). CyStack’s automated assessment recorded 9 issues to review after completing 100% of applicable checks. The website owner should address “Allowed browser content (CSP)” first, then review the remaining items in order of impact.
Does uptodown.com show known scam, phishing, or malware signals?
At assessment time, CyStack did not find uptodown.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 only for email addresses whose domain exactly matches this target. A record is not counted merely because someone visited or signed in to this website.11 matching email exposure records
11Matching email exposure records

These matching email records were observed previously, but they may already have been addressed or may no longer be valid. The device count estimates infected devices associated with these email records; it is not the number of devices owned by the organization.
Frequently asked questions
What affects the security of uptodown.com?
A valid SSL certificate still does not prove that uptodown.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 uptodown.com use HTTPS, and is its SSL certificate valid?
uptodown.com used a valid SSL certificate at assessment time, valid until January 23, 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 uptodown.com.
Allowed browser content (CSP)The inspected root HTML response does not include a Content-Security-Policy header.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.
Scope of this check
This check only evaluates the homepage response and content that the scanner could reach. Other pages and sign-in flows may use different settings.
DMARC blocking policyThe effective DMARC policy is none and applies to 100% of messages.High
Why it matters
A policy of quarantine or reject tells receiving services to move suspicious mail to spam or refuse it. A monitoring-only policy (p=none) records the problem but does not ask receivers to stop spoofed mail.
What to do
After every legitimate sender passes DMARC, move gradually to quarantine and then reject, covering 100% of messages.
Correct file-type handling (nosniff)The inspected root response does not set X-Content-Type-Options to nosniff.Medium
Why it matters
Without the nosniff setting, a browser may guess a file's type and treat harmless-looking content as executable code. This can turn an incorrect Content-Type into a security issue.
What to do
Send X-Content-Type-Options: nosniff on every response and return an accurate Content-Type.

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 @uptodown.com email addresses appeared in exposed data or information-stealer (infostealer) logs?
There are currently 11 exposed email records matching the uptodown.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 uptodown.com expose?
The assessment observed 1 public IPs and 2 open ports for uptodown.com; the infrastructure appears to be operated by OVH SAS. An open port is not automatically a vulnerability, but every public service should be updated and appropriately restricted.
How many subdomains of uptodown.com have been discovered?
The assessment observed 1,500+ public subdomains of uptodown.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.
