Implement yr_scanner_scan_mem_blocks()-based io. Reader . . . - GitHub As per the title, would it be possible to provide a scanning interface that accepts an io Reader The implementation could be based on a streaming interface by implementing the YR_MEMORY_BLOCK_ITERATOR* parameter for yr_scanner_scan_mem_
Scanner | hillu go-yara | DeepWiki Overview The Scanner provides a flexible interface for scanning various data sources with YARA rules Unlike using the Rules object directly (Rules), Scanner offers thread-safe variable definition and additional configuration options It is a key component in go-yara's architecture that wraps an underlying YR_SCANNER from the YARA C library
Everyones Detected: Roblox, Part I — YARA Memory Scanning To recover the original string from a RBX::Scanner::Scan call, this encryption would need to be reversed Testing The Effectiveness of RBX::Scanner I was curious—just how effective is Roblox’s custom YARA-based engine? To find out, I created rrlog, a tool that logs ruleset matches during memory scans
Configuring the Yara Scanner — DFIR ORC documentation scan_method="blocks" Note The filemapping value for this option is discouraged as it will consume a lot of memory for the scanning process when dealing with large files block Attribute ¶ Integer specifying the size in bytes of the buffer Yara will use to scan each file The following multipliers can be suffixed to this number: K, M, G (for
yara package - github. com hillu go-yara-exp v4 - Go Packages A Compiler encapsulates the YARA compiler that transforms rules into YARA's internal, binary form which in turn is used for scanning files or memory blocks Since this type contains a C pointer to a YR_COMPILER structure that may be automatically freed, it should not be copied
scanner. rs - source This is a per-thread id allocated at the start of yr_scanner_scan_mem_blocks, which is used to index into various arrays during the scan It is deallocated when yr_scanner_scan_mem_blocks returns
4. 1: Extended iterator interface should be made (mostly . . . - GitHub Returning -1 from first and next is not enough, either the scanner or the iterator must remember that the last call to first next resulted in a "not ready" error, so that the next call to yr_scanner_scan_mem_blocks can retry the operation
YARA newbie trying to understand use of - GitHub In the current implementation base is always 0 when scanning a file, and the virtual address of the memory block when scanning a process memory What the documentation is trying to say is that you must always be prepared for base being something different than zero
Optimize memory usage when scanning processes and files #33 So far, my solution was to no longer read data into each block in yr_process_get_memory and instead just stuff the process handle into the data field in the block structure Then, when iterating over blocks in yr_rules_scan_mem_blocks I can call ReadProcessMemory to load the data for that one block, scan it, release it, and move onto the next
