Unpacking the Malware Matryoshka: RTF Exploits Hidden in Office Docs!
Ever seen a Microsoft Office document that acts like Russian dolls? Thanks to crafty hackers, malicious RTF files are now hiding inside OOXML documents. It’s like malware inception, but with more coding and fewer dreamscapes. The Equation Editor exploit is alive and kicking, proving that some exploits just refuse to retire gracefully.
Hot Take:
It seems like the world of cybercrime is taking a page out of traditional Russian culture and embracing the art of the Matryoshka doll. Just when you think you’ve reached the last layer, surprise! There’s another one waiting to spring a nasty surprise. Office documents are back in the game with a new twist that’s got us all saying, “Oh, not you again!” The cybercriminals must be laughing maniacally while sipping their cyber-mojitos.
Key Points:
– Cybercriminals are using an Office document that behaves like Russian Matryoshka dolls, concealing one layer of malicious code within another.
– Microsoft’s new rules to prevent automatic VBA macros execution have led criminals to innovate with RTF documents exploiting CVE-2017-11882.
– The malicious RTF document is cleverly hidden inside an OOXML document to evade detection.
– The RTF document contains shellcode that triggers the Equation Editor exploit, leading to further malicious payload delivery.
– The payload is an obfuscated DLL, hinting at a potential connection to the Formbook malware family.
