Shortened URL Security Tips Criminals will use shortened URLs to direct victims to phishing sites or initiate a download of malicious software on to your device. Finding no other algorithms that were suitable for this use case as well as safe to use, we created a new, header-specific compression scheme that operates at a coarse granularity; since HTTP headers often dont change between messages, this still gives reasonable compression efficiency, and is much safer. This is because of the URLs main use: addressing web pages. Compressed URLs can also be used to distribute malware. HPACKs huffman encoding, for reasons of CPU efficiency and security, pads out huffman-encoded strings to the next byte boundary; there may be between 0-7 bits of padding needed for any particular string. Attackers can use compressed URLs to hide links to websites that host malware or to download malware directly to the user's device. be held for a while in order to allow them to merge with a subsequent one.
