Re: [HTCondor-users] Fwd: URGENT - HTcondor condor_8.4.9-382747-ubuntu14_amd64.deb INFECTED - Benjamin.

ÂI have rebuilt HTCondor on a fresh Ubuntu14 installation, I checked the signatures and checksums. I am confident that this is a false positive.

This particular executable is only used to determine standard universe support. If Dr. Web deletes this file, most of HTCondor will continue to work properly.

It seems I was unable to extract the file in question

"condor_ckpt_probe" is indeed the specific file it's
alerting on.

We ran drweb's scan against a release that is two years old
(before Mirai was discovered).  The scan showed positive:

[moate@localhost ~]$ sudo drweb-ctl scan condor-8.2.3-274619-ubuntu_14.04_amd64.deb
/home/moate/condor-8.2.3-274619-ubuntu_14.04_amd64.deb//data.tar.gz//gziped.gz//./usr/lib/condor/libexec/condor_ckpt_probe - infected with Linux.Mirai.54
Scanned objects: 1, scan errors: 0, threats found: 1, threats neutralized: 0.
Scanned 31907.75 KB in 5.87 s with speed 5432.03 KB/s.

So right now it's looking like a false positive.  We're working
at getting more exact verification.

     Yep. Drweb is a very good antivirus. For me, sometime, i can't finish
     the download. Also, it is the easiest one for HPC cluster.

       I got drweb working on the 32-bit EL6 BaTLab platform, and it
       does indeed seem to think that
       condor_8.4.9-382747-ubuntu14_amd64.deb is a threat, specifically
       the usr/lib/condor/libexec/condor_ckpt_probe file inside.  I
       tried to extract the file uzing xzcat and tar, but for some
       reason have been unable to so far, even though strace claims
       it's being written to disk.
