Previously most of the OS would be in memory and only page out if absolutely needed. Once that buffer or cache runs out, all those mostly extraneous IOPS just pile up, and the SSD will basically never catch up, because the technology fundamentally cannot catch up to a sustained load like that, but the load is sustained because all the software was designed with "SSDs are fast and lots of small writes will be fast" so they just keep growing the queue. That means your busy machine goes from perfectly fine to nearly locked up, because even the OS now thinks file operations are "cheap" enough to block on and rely on in all sorts of hot paths. Then they slow WAY down, like slower IOPS than my spinning rust disk.
However, consumer SSDs are only "fast" until they run out of DRAM buffer or SLC cache.
Everyone thinks they are "fast" so they do all sorts of file operations that would have previously been considered too slow. I find that SSDs have a terrible failure mode too. > Thus, if a user copies a file and goes to paste it elsewhere they will instead paste a shortcut that looks like their intended file, but actually runs the malware. > - Assings this shortcut to the clipboard, overwriting the original file reference > - Create a shortcut that looks like the original file (using icons from SHEL元2) but instead invokes the malware > - Iterate over FileDescriptor entries in the system clipboard (Supposedly this will be accessing the contents of the host) > - Create a temporary directory using Files.createTempDirectory(.) > - Start a repeating thread to run the following actions: If this condition is met, an attempt to escape the sandbox system is made. It checks if its in a sandboxed windows environment by checking if the current user is WDAGUtilityAccount, which is part of the Windows Defender Application Guard. Something not commonly seen in JVM malware that is present here is a class titled VMEscape.
