This looks like a useful example of a fake software site being used as a malware delivery lure.

What the quoted links show

• The GitBook article describes a fake ILSpy-themed site allegedly distributing a payload tied to browser/search hijacking behavior.
• The VirusTotal link points to a specific sample hash and shows how multiple engines classify that file.
• The Kaspersky OpenTIP link is another reputation lookup for the same hash.

Important limitation

I cannot safely confirm from links alone that every related file or domain in that campaign is malicious, and VirusTotal detections by themselves are not perfect proof. They are useful indicators, but false positives and naming differences do happen.

What can be concluded more safely

If a file is being presented as ILSpy but does not come from the official project source, that is a clear security risk.

In general, a fake software download page combined with multi-engine detections and a threat-intel writeup is a strong reason to avoid the file entirely and treat it as suspicious unless verified by trusted researchers or the legitimate vendor/project.

Practical takeaway

• Only download ILSpy from its official project page or trusted official repository.
• Verify the publisher, signature, and hash where possible.
• If someone already executed the sample, they should run a full scan with a reputable antivirus product and check browser shortcut targets, installed extensions, startup entries, and scheduled tasks.
• If deeper analysis is needed, posting the file hash, download URL, and any behavior observed will help the thread move forward without guessing.

Why this matters

Search hijackers and fake installer campaigns often rely more on user trust than on sophisticated exploitation. Even when the payload is not highly advanced, it can still change browser settings, add persistence, and expose users to further unwanted downloads.

The safe conclusion is to avoid unofficial ILSpy download pages and treat this sample as suspicious pending fuller analysis.
