[QUOTE="Parsh, post: 876702, member: 58090"] I cannot tell for sure, but that [I]could[/I] be a reason for the file to be allowed by all AVs — to not raise a most certain FP. On the premise that the user has created the file intentionally for use. Ultimately it's an exe file, still it's interesting that static/real-time scans also got nothing. If that's the reason, typical AVs that use that check might not flag your sample. But tools like dedicated anti-ransomware apps that mainly rely only on encryption-like behavior may block it. Could you create a different VM, using a fresh [I]new[/I] image, then import and test this file with some AVs again when time allows? [/QUOTE]
