In the filter used in uBlock Origin EasyPrivacy<\/a><\/noindex> , rules have been added to block typical network port scanning scripts on the user's local system. Recall that in May it was discovered<\/a><\/noindex> that local port scanning occurs when opening the website eBay.com. It turned out that this practice is not limited to eBay, and many other sites<\/a><\/noindex> (Citibank, TD Bank, Sky, GumTree, WePay, etc.) perform local system port scanning when their pages are opened, using code to detect attempts from compromised computers provided by ThreatMetrix.<\/p>\n

In the case of eBay, 14 network ports associated with remote access servers such as VNC, TeamViewer, Anyplace Control, Aeroadmin, Ammy Admin, and RDP were checked. Presumably, this check is performed to determine<\/a><\/noindex> for traces of malware infection in order to prevent fraudulent purchases using botnets. Scanning can also be used to gather data for indirect user identification.<\/a><\/noindex>.<\/p>\n

The scanning technique is based on attempting to establish connections to various network ports of the host 127.0.0.1 (localhost) through WebSocket<\/a><\/noindex>The presence of an open network port is indirectly determined based on the difference in connection error handling for active and unused network ports. WebSocket allows only HTTP requests to be sent, but such a request to an inactive network port fails immediately, while a request to an active port only fails after some time spent attempting to establish a connection. Additionally, in the case of an inactive port, WebSocket returns a connection error code (ERR_CONNECTION_REFUSED), whereas for an active port, it returns a connection negotiation error code. <\/p>\n

\"uBlock<\/a><\/noindex><\/center><\/p>\n

Besides port scanning, WebSockets can also starting February 17, initially for a small percentage of users and then gradually expanding the coverage.<\/a><\/noindex> be used for attacks on web developers running WebSocket handlers for React applications on their local systems. An external site can scan network ports, detect the presence of such a handler and connect to it. If the developer makes a mistake, the attacker can access debugging data, which may include snippets of confidential information.<\/p>\n
