If this value + 28 doesn't point to the last longword of the file, adjust so it does :).

prg in a hex editor and check the longword at offset 2. For a lot of cases this isn't a big problem since the memory is zeroed, but for some cases (for example running from floppy - no idea why this happens!) the memory is dirty so GEMDOS tries to do relocation (and fails). Sometimes this offset does not point there, but 2 or 4 bytes after. This should point at the last longword of the binary (which is 0.L). PRG_dsize and PRG_ssize are zero for PackFire programs, so this is simplified to PRG_tsize + 0x1C. From here (GEMDOS Processes) I saw that the relocation (AKA 'fixup') offset is calculated like this: PRG_tsize + PRG_dsize + PRG_ssize + 0x1C. Includes: - apLib - Zstd - zLib - lz4 (fast and HC) - lz78 - lzss The zip. PRG from floppy.ДЄnyway, the problem (I think!) is that the pointer to the relocation table is wrong. Heres a set of string compression / decompression routines, along with a test. This step mitigates against triggering false positives and allows you to refine your configuration.ДЇor more information, see KB87843 - List of and best practices for Endpoint Security Dynamic Application Containment rules.Okay, disregard what I wrote above, I think I have a fix for this:ДЇirstly, most of the times the 'TOS error #35' bug happens when you run the.

If a Threat Hunting table has been created, use the rules contained to search for malware related to this campaign.

This campaign was researched by Walmart GlobalTech Researchers and shared publicly. Our ATR Team gathers and analyzes information from multiple open and closed sources before disseminating intelligence reports. This fact might indicate that they share the same or similar dev teams or build processes. The Sugar ransom note as well as the decryptor page share striking resemblances with two other ransomware families, namely Revil and Cl0p. The ransomware is written in Delphi and uses a crypter that's made up of a modified version of RC4, leading to APLib decompression. The ransomware has been called Sugar by the research team that analyzed the malware. Recently a Ransomware as a Service (RaaS) was identified to target end-user systems rather than going after bigger organization infrastructure.
