What happens when ransomware can't even decrypt the files it encrypted? This latest blog from Morphisec threat researcher Yonatan Edri takes a closer look at VECT ransomware and uncovers a troubling reality: some victims may be left with files that are renamed, partially encrypted, corrupted, or otherwise unrecoverable - even when a decryptor is available. While researchers have already documented VECT's nonce management flaw, our analysis found additional Windows-specific implementation issues that can create inconsistent file states and complicate recovery efforts. Key findings: ✅Files are renamed before encryption begins, meaning a .vect extension doesn't necessarily indicate successful encryption. ✅Medium-sized files may be processed through a flawed buffer handling routine, potentially resulting in failed or incomplete encryption. ✅Shared global buffers introduce the possibility of file corruption under concurrent execution. ✅Large files can be modified using multiple encryption operations while retaining insufficient metadata for reliable restoration. The result? Not all ransomware incidents produce cleanly encrypted files—and not all decryptors can put them back together. The research reinforces an important lesson for defenders: recovery is not always guaranteed. Organizations need security strategies focused on preventing ransomware execution before encryption occurs, while maintaining the ability to recover affected files when attacks succeed.
