Controversy Surrounding E-hentai: Alleged Manipulation of Images by Malicious H@H Network Nodes
Background Information There exists an open-source software known as "Ehviewer," developed unofficially as a reading tool for E-hentai.
The main server of E-hentai is situated in a small country, while image distribution tasks are handled by the globally dispersed H@H network(including within mainland China).
For regular users, aside from basic website services, E-hentai's primary server is responsible for thumbnail distribution and allocating the nearest H@H servers based on users' IP addresses.
As E-hentai has been blocked by China's Great Firewall (GFW), Ehviewer features a special function to bypass the firewall, enabling users to directly access E-hentai using mainland China IP addresses.
What Happened? Recently, some Ehviewer users who had activated the "bypass firewall" feature noticed that while the thumbnail images appeared normal, the bigger and full-size images contained anti-China watermarks.
Notably, images retrieved from H@H servers in other regions like Japan and the United States were unaffected.
Gallery uploaders have denied uploading any anti-China content.
There Can Only Be One Truth! Investigations have revealed that individuals with anti-China sentiments deployed H@H servers in Greater China and manipulated their servers' cache to insert anti-China watermarks into otherwise regular images.
Due to E-hentai's server allocation strategy, only users bypassing the firewall and using mainland China IP addresses would be assigned Chinese H@H servers, leading to the receipt of these images with anti-China content.
Furthermore, although a certain branch of Ehviewer was suspected of introducing a "distribution of anti-China watermarks" feature during an update, this incident was not triggered by that specific branch.
Latest Updates Some branch of Ehviewer have hastily incorporated a feature to verify whether images have been manipulated.
Rumors suggest that affected Ehviewer developers are contemplating permanently discontinuing support for relevant branches.
E-hentai has banned the involved accounts, though the existence of residual anti-China H@H servers remains uncertain.
