Abstract: A method, system and related apparatus are described, the system comprising a caching-capable element which is part of a data network, which receives a request from a downstream client device, the request including a content request, the content request including a Universal Resource Identifier (URI) and an explicit caching request, the caching request includes a unique content identifier which is independent of the URI, and optional expiration date information, a comparator included at the caching-capable element which compares the caching request against the existing cached content, and if the requested content is cached then the caching-capable element forwards the cached copy of the requested content to the client device, and if the requested content is not cached, then the caching-capable element forwards the request to a further upstream device, and, upon reception of the requested content from the further upstream device, returns the requested content to the requesting downstream device, and caches the requested content for further distribution to other clients. Related methods, systems and apparatus are also described.

Abstract translation: 描述了一种方法，系统和相关装置，该系统包括作为数据网络的一部分的缓存能力元件，其接收来自下游客户端设备的请求，所述请求包括内容请求，所述内容请求包括通用资源 标识符（URI）和显式缓存请求，缓存请求包括独立于URI的唯一内容标识符，以及可选的有效期限信息，比较缓存请求与现有缓存内容进行比较的可缓存请求元素 ，并且如果所请求的内容被缓存，则可缓存能力的元素将所请求的内容的高速缓存的副本转发给客户端设备，并且如果所请求的内容没有被高速缓存，则可缓存的元件将该请求转发到另一个上游设备 并且在从所述另外的上游设备接收到所请求的内容时，将所请求的内容返回给所述请求的下行链路 m设备，并缓存所请求的内容以进一步分发给其他客户端。 还描述了相关方法，系统和装置。

Abstract: In one embodiment, a system includes a central processing unit (CPU) to identify a ransomware process which encrypted a plurality of files yielding a plurality of encrypted files, in response to identifying the ransomware process, dump a memory space and a state of the CPU yielding a memory dump, and search the memory dump for a plurality of candidate encryption keys, and a decryption engine to attempt to decrypt at least one encrypted file of the plurality of encrypted files with different candidate encryption keys of the plurality of candidate encryption keys until the at least one encrypted file is successfully decrypted with one candidate encryption key of the different candidate encryption keys, and decrypt the plurality of encrypted files using the one candidate encryption key. Related apparatus and methods are also described.
