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



It seems I was unable to extract the file in question
because drweb was deleting it as soon as it was written.
"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.
