python33.dll

Python33.dll is a harmful malware that can infiltrate your system through various channels, including suspicious downloads, emails, or websites. Once inside, it can steal personal information, disrupt operations, or even hold your data hostage for ransom. This malicious software has been observed being uploaded to webshells, where it's sideloaded alongside other files such as inicore_v2.3.30.dll and CreateTsMediaAdm.dll, both of which have been linked to previous attacks by Emissary Panda, a cyber espionage group. A code comparison between the PYTHON33.dll and the inicore_v2.3.30.dll file, which was sideloaded in previous Emissary Panda attacks, indicates significant similarities. The same applies when comparing PYTHON33.dll and CreateTsMediaAdm.dll. In particular, Figure 9 shows a code comparison between PYTHON33.dll (right) and inicore_v2.3.30.dll (left), with the latter having been sideloaded to run the SysUpdate tool in an earlier Emissary Panda campaign. Further analysis reveals that both PYTHON33.dll and CreateTsMediaAdm.dll employ an eight-byte XOR key to decrypt a piece of shikata_ga_nai obfuscated shellcode, as demonstrated in the code diff in Figure 8. A binary comparison between PYTHON33.dll and CreateTsMediaAdm.dll libraries yields a striking similarity score of 97% with a 99% confidence level. This high degree of resemblance suggests a shared origin or purpose, underscoring the persistent threat posed by this sophisticated malware.
