u mad Heartbleed ? ...

====
Release date: 04/30/2014
Product: OpenSSH
Vendor: http://www.openssh.com/
CVE candidate number: CVE-2018-XXXX (maybe 2020+...)
====

We found two years ago a memory disclosure vulnerability in the OpenSSH server
which allows to remotely extract data from the sshd server's children processes
memory zones.

This vulnerability exploits a bad check on the network layer of the sshd server
that we trigger to retrieve all children processes memory sections thereby
allowing us to dump:
- system users hashes
- keys
- many random things ;)

This exploit was tested on:
- SSH-2.0-OpenSSH_5.1p1 Debian-5
- SSH-2.0-OpenSSH_5.1p1 DragonFly-20080927
- SSH-2.0-OpenSSH_5.2p1 FreeBSD-20090522
- SSH-2.0-OpenSSH_5.5p1 Debian-6+squeeze3
- SSH-2.0-OpenSSH_5.8p1 Debian-7ubuntu1
- SSH-2.0-OpenSSH_6.1p1 Debian-4
- SSH-2.0-OpenSSH_6.2p2-hpn13v14 FreeBSD-openssh-portable-6.2.p2_3,1
- SSH-2.0-OpenSSH_6.4p1 Debian-1~bpo70+1
- SSH-2.0-OpenSSH_6.4p1 FreeBSD-openssh-portable-6.4.p1,1
- SSH-2.0-OpenSSH_6.5p1 CentOS RHEL
- SSH-2.0-OpenSSH_6.6p1 Ubuntu-2ubuntu1
- ... many more

Enough bullshit, POC TIME !

Since we detected few exploitations tentatives of this vulnerability through
our honeypots network, we concluded that an other team / organization
discovered it and decided to sell it.
(Yes, we build honeypots rules for our exploits)

We don't have access to exploit black markets and we are now happy to offering
it for sale to you both black and white hats.

== How to buy ==
Send 66666.6 BC (Blackcoin) to BLkrmaoY7XQfUUCSCJfHGq8tTig5qJmZXT
or
2000000 WC (Whitecoin) to Wbi8SqBjymeedtNwM9zhaSm3bMnZvgifR2
or
20 BTC (Bitcoin) to 14PEL35LQf81oCvSPurhoyTSvosvtQT7u3

then send your transaction ID by mail to olckrrii3@openmailbox.org and we will
send you the download link and password. (PGP recommended)

icanhaze.c sha1:d7faeb46f10ea6b7058a116043c1f0ce7a158c7f

Please note that we are busy and we will NOT answer to questions, social
engineering tentatives or dumb comments. Price is non-negotiable.
