Hi all, even though I filter incoming messages with ClamAV, last Monday I received a mail with two suspicious attachments. They were PE32+ executable (DLL) (GUI) x86-64, for MS Windows. I uploaded the samples to virustotal.com, who reported they were recognized as troyans. I saved the viral message and uploaded it to https://www.clamav.net/reports/malware. On Tuesday I received the following message:
-------- Forwarded Message -------- Subject: ClamAV.net - Your malware submission Date: Tue, 16 Nov 2021 07:23:26 +0000 (UTC) From: nore...@clamav.com To: ves...@tana.it Alessandro Vesely, Thank you again for your submission. Your File: purchase-ORD (SHA256: 2ac2bb49a9135954a298cbb3e52b3ecfcb1e5e2dc6d83fac7052d4c3833ac11a) Our initial assessment shows that this file is possibly clean. If you provided a description that suggests otherwise, we will further examine the sample & proceed from there. -The ClamAV team -------- End Of Forwarded Message -------- "If you provided" looked like a future unreal conditional to me. It is certainly unreal, given the From:. Anyway, I replied something like the following text: https://www.virustotal.com/gui/file/40392920e907b85591dac15d2f4ca49a477e0401abb3334cda2b45a9a513fd58 10 security vendors flagged this file as malicious 40392920e907b85591dac15d2f4ca49a477e0401abb3334cda2b45a9a513fd58 Notificaion-30714_20211115.xll https://www.virustotal.com/gui/file/8c0b4c9fe9e49b8eaf449aad36ebb39235835ab2c3a49584be7d0697ecb82c21 11 security vendors flagged this file as malicious 8c0b4c9fe9e49b8eaf449aad36ebb39235835ab2c3a49584be7d0697ecb82c21 Document-055293_20211115.xll However, on Wednesday it bounced, because ClamAV's mail server, tad.clamav.net, is persistently down. I thought that was a temporary hiccup and pehaps the ClamAV team wasn't even aware of it. So I saved the bounce, which contained the whole original message, and uploaded it to the same location, explaining that the attachment was a reply to their message, not a sample. Guess what I received on Thursday? -------- Forwarded Message -------- Subject: ClamAV.net - Your malware submission Date: Thu, 18 Nov 2021 08:52:21 +0000 (UTC) From: nore...@clamav.com To: ves...@tana.it Alessandro Vesely, Thank you again for your submission.

Meanwhile, tad.clamav.net is still down.
