About Z-LIB.SU
We reviewed z-lib.su and found a mix of positive and cautionary signals. The site does not currently look like a confirmed scam, but the evidence is not strong enough to treat it as fully established either. The current trust score is 59/100. Key signals include external redirect behavior, generic page wording, and a redirect to another domain (z101.by). Verify key details and recent independent feedback before relying on this site for important actions.
FAQ
Is z-lib.su safe?
Current analysis does not clearly confirm that z-lib.su is safe. Important context includes external redirect behavior and generic page wording. Independent verification is still recommended before relying on it.
Why does z-lib.su have mixed reputation signals?
Key factors include registrar information (REGRU-SU), hosting in SG, and a domain age of 24 months. Major malware and phishing engines did not report active blacklist detections at the time of review. The trust score blends security detections, domain and infrastructure signals, and on-page behavior patterns. Overall, this points to a mixed profile rather than a clearly safe one.

Security Analysis
Z-lib.su is affiliated with the Russian Federation, a nation that initiated a military attack, thus committing a crime against humanity in the form of war against Ukraine for the past 3 years. Our company, Gridinsoft, is based in Ukraine.
The ongoing war has resulted in tragic losses, with our children, parents, and friends facing daily hardships due to the deliberate actions of the Russian military. Homes are being destroyed, and millions of our fellow citizens have been forced to leave their residences.
This is not a political statement but rather a heartfelt plea. We earnestly ask that you refrain from utilizing services provided by websites from Russia. We appeal to your sense of humanity—please avoid purchasing their products or engaging in business transactions with them.
It is critical to recognize that each individual's choices contribute to the financial resources available to the Russian Federation, which directly impacts its ability to sustain this war. Your conscientious decisions can play a role in promoting peace and stability in Ukraine.
