Downloading a file from the web remains a common action, but the nature of the associated risks has profoundly changed in recent years. Infostealer malware, which steals passwords, session cookies, and banking data, is now directly linked to files downloaded from poorly identified sources. Finding the gems of the web for safe downloads therefore requires knowing how to distinguish a reliable source from a trap, even before clicking.
Infostealers and downloaded files: the threat that site lists ignore
Cybersecurity reports published in 2025 point to a significant increase in infostealer infections compared to the previous year. This type of malware does not encrypt your files like ransomware: it silently copies your credentials, session tokens, and banking details, then transmits them to a remote server.
Two behaviors consistently appear in infection analyses: downloading software from unsafe sources and attempting to activate programs via cracks or keygens. Compressed files containing a hidden executable (often a .exe renamed to .zip or .rar) are the main vector.
Specifically, a site that offers paid software for free download without any visible compensation (no legitimate advertising, no freemium model, no mention of an open-source license) presents a high risk. The absence of an identifiable business model is a more reliable warning signal than the site’s graphical appearance.
To spot good deals on Mes Liens Favoris, it is better to rely on directories that filter and verify the referenced sources rather than navigating blindly through search results.
Criteria for the reliability of a download site: comparative reading grid
Competitors list sites without always explaining how to assess their reliability. Several technical indicators allow for quick sorting of a source before downloading anything.
| Criterion | Reliable site | Risky site |
|---|---|---|
| Protocol | HTTPS with valid certificate | HTTP or self-signed certificate |
| Legal mentions / contact | Verifiable contact information, privacy policy | No mention, generic form |
| Business model | Legitimate advertising, freemium, donation, open-source license | No visible model or intrusive ads (pop-under, redirects) |
| Type of file offered | Official installer, verifiable archive (published hash) | Renamed executable, password-protected archive without reason |
| Domain history | Stable domain for several years | Recent domain, frequent address changes |
A site that regularly changes its domain name almost always indicates a prior judicial blocking. In France, blocking procedures have accelerated since 2024, particularly for pirate sports streaming platforms and direct download (DDL) sites.
The case of password-protected archives
A .rar or .7z archive that requires a password provided on the download page rarely serves to protect your privacy. This technique prevents antivirus software from analyzing the content before extraction. If the site asks you to disable your antivirus to “ensure the proper functioning” of the file, close the tab.
Blocking pirate sites in France: what has changed recently
The French legal framework has tightened in the past two years regarding the blocking of illegal download sites. Parisian courts have ordered the blocking of dozens of domains related to pirate sports streaming and IPTV platforms, with procedures that now involve several technical intermediaries simultaneously (access providers, DNS, hosts).
The automated blocking of pirate sites is becoming widespread in France, which explains the constant migrations of some platforms to new addresses. For users, this instability is an indicator in itself: a legitimate site does not need to change its URL every month.
The Digital Services Act (DSA), a European regulation that has come into effect, also imposes transparency obligations on online platforms regarding content moderation. Download sites that do not comply with these obligations are subject to sanctions, which reinforces the distinction between compliant platforms and sites operating outside the framework.
Practical consequences for users
- A site blocked by a French ISP may still be accessible via a VPN or third-party DNS, but accessing it does not eliminate the legal risk or the malware risk associated with the site itself.
- Specialized link directories that verify the availability and legality of referenced sources help avoid redirects to ghost or compromised domains.
- Legal platforms (Steam, Spotify, Google Play, FossHub, GitHub) remain the safest sources for downloading, even if their catalog does not cover all needs.
File verification after download: technical reflexes
Finding a reliable source does not exempt you from verifying the downloaded file. Two complementary methods significantly reduce the risk of executing malicious software.
Comparing the file’s hash with the one published by the publisher remains the most reliable method. Open-source projects on GitHub or FossHub systematically publish the SHA-256 fingerprints of their releases. If the hash does not match, the file has been modified.
The second verification involves submitting the file to an online multi-antivirus analysis service before opening it. These services cross-reference results from several dozen detection engines. A file flagged by a single engine may be a false positive; a file flagged by five or more engines should be deleted without hesitation.
- Check the SHA-256 hash published by the official software publisher.
- Submit the file to a multi-engine scanner before any execution.
- Examine the actual file extension (a .exe disguised as .pdf remains an executable).
- Always refuse to disable an antivirus or firewall at a site’s request.
The most dangerous files are not those that trigger an alert, but those that go unnoticed. Recent infostealers are designed to evade classic detections, making hash verification all the more relevant: it does not depend on your antivirus’s signature database.
The search for rare or free content on the web will not disappear. However, the cost of a mistake has increased: a single compromised file can expose all your online accounts in seconds. Cross-referencing the reliability of the source, the consistency of the site’s business model, and the technical verification of the file constitutes the minimal foundation before any download.
