A short presentation on the Latest dumb of nsa tools by Shadowbroker hacker group. How to attack how to prevent the attack. Also about the new ransomware wanna cry 2.0
In theory, post-exploitation after having remote access is easy. Also in theory, there is no difference between theory and practice. In practice, there is. Imagine a scenario, where you have deployed a malware on a user’s workstation, but the target information is on a secure server accessed via two-factor authentication, with screen access only (e.g. RDP, Citrix, etc.). On top of that, the server runs application white-listing, and only the inbound port to the screen server (e.g. 3389) is allowed through the hardware firewall. But you also need persistent interactive C&C communication (e.g. Netcat, Meterpreter, RAT) to this server through the user’s workstation.
I developed (and will publish) two tools that help you in these situations. The first tool can drop malware to the server through the screen while the user is logged in. The second tool can help you to circumvent the hardware firewall after we can execute code on the server with admin privileges (using a signed kernel driver). My tools are generic meaning that they work against Windows server 2012 and Windows 8, and they work with RDP or other remote desktops. The number of problems you can solve with them are endless, e.g., communicating with bind-shell on webserver behind restricted DMZ. Beware, live demo and fun included!
This presentation is a fun introduction to the tools used by script kiddies, namely the Remote Admin Tools (or Remote Access Trojans). These GUI based hacking tools include a lot of funny and scary features.
Sandbox detection: leak, abuse, test - Hacktivity 2015Zoltan Balazs
This document discusses techniques for detecting and evading malware analysis sandboxes. It begins by outlining common sandbox detection methods like checking screen resolution, installed software, CPU/system information, and network settings. It then discusses challenges like simulating sleep functions and network connections. The document emphasizes that while evading analysis is possible, manual review remains difficult to defeat. It concludes by advising blue teams to thoroughly test sandboxes and customize them to their environment before purchasing.
[ENG] OHM2013 - The Quest for the Client-Side Elixir Against Zombie Browsers - Zoltan Balazs
The document discusses the challenges of protecting against malware on web browsers through client-side solutions alone. It describes how the author was able to bypass protections in various internet security suites and anti-malware products by creating malicious browser extensions. While some vendors were able to address the issues, the document argues that client-side only solutions are fundamentally limited. It suggests focusing on server-side protections instead of seeking a "client-side elixir" for fully preventing malware.

Examples of tasks that can be performed include port scanning, vulnerability assessment, exploiting known issues, and gaining access to systems using payloads and meterpreter sessions. The document warns that Metasploit should only be used for legitimate security testing and cautions about the potential risks if misused.
Introduction To Exploitation & MetasploitRaghav Bisht
Penetration testing involves evaluating systems or networks using malicious techniques to identify security vulnerabilities. It is done by exploiting vulnerabilities to gain unauthorized access to sensitive information. Common vulnerabilities arise from design errors, poor configuration, and human error. Penetration testing is conducted to secure government data transfers, protect brands, and find vulnerabilities in applications, operating systems, databases, and network equipment. Metasploit is an open-source framework used for hacking applications and operating systems that contains exploits, payloads, and modules. Msfconsole is an interface used to launch attacks and create listeners in Metasploit.

Hacking Highly Secured Enterprise Environments by Zoltan BalazsShakacon
In theory, post-exploitation after having remote access is easy. Also in theory, there is no difference between theory and practice. In practice, there is. Imagine a scenario, where the hacker/penetration-tester has deployed a malware on a user's workstation, but the target information is on a secure server accessed via two-factor authentication, with screen access only (e.g. RDP, Citrix, etc.) On top of that, the server runs application white-listing, and only the inbound port to the screen server (e.g. 3389) is allowed through the hardware firewall. But you also need persistent interactive C&C communication (e.g. Netcat, Meterpreter, RAT) to this server through the user's workstation.
I developed (and will publish) two tools that help the community in these situations. The first tool can drop malware to the server through the screen while the user is logged in. The second tool can help to circumvent the hardware firewall after one can execute code on the server with admin privileges (using a signed kernel driver). My tools have been tested against Windows server 2012 and Windows 8, and they work with RDP or other remote desktops (e.g. Citrix). The number of problems one can solve with them are endless, e.g., communicating with bind-shell on webserver behind restricted DMZ. Beware, live demo and fun included!
Introduction of ShinoBOT (Black Hat USA 2013 Arsenal)Shota Shinogi
ShinoBOT is a penetration testing tool that simulates a remote access tool (RAT) to measure an organization's defenses against advanced persistent threats. It connects to the ShinoC2 command and control server every 10 seconds to receive and execute jobs. ShinoC2 allows penetration testers to create jobs that are then assigned to compromised systems running ShinoBOT. The tools aim to help security teams understand what would happen if a real APT successfully installed a RAT on their network by testing incident response and log monitoring capabilities. Upcoming features for ShinoBOT include taking webcam snapshots, encrypting its communications and hiding using a kernel driver to simulate more advanced adversary techniques.
To modify the fake filesystem in Kippo honeypot:
1. Browse to /honeydrive/kippo/data/fs
2. Create a new directory or file (e.g. myfiles)
3. Modify the script create_filesystem.py to include the newly created directory/file in the fake filesystem
4. Re-run the script to rebuild the fake filesystem pickle file with the modifications
5. Restart Kippo using ./start.sh
6. Now when an attacker SSH's in, they should see the new myfiles directory/file
The fake filesystem is built dynamically using Python scripts and stored in a pickle file. Modifying the creation script allows customizing what
This document describes a new technique called "IRONSQUIRREL" for encrypting browser exploits during delivery to prevent their analysis and leakage. It uses elliptic curve Diffie-Hellman key exchange to encrypt the exploit code between the server and client browser. This makes the exploit non-replayable and difficult for reverse engineers to analyze from network traffic alone. The document provides details on how IRONSQUIRREL works and recommendations to further obstruct analysis through techniques like one-time URLs, anti-debugging, and obfuscation.
The document provides information on simple hacking techniques that require minimal technical skills. It discusses recommended operating systems for hacking (Linux distributions and Android), and provides step-by-step instructions for hacking CCTV cameras, Windows PCs from a guest account, and wireless networks using the Aircrack-ng suite. It also lists Android apps that can be used for network scanning, man-in-the-middle attacks, password cracking, and spamming/spoofing communications apps like WhatsApp. Most techniques discussed require a rooted Android device. Risks of rooting like voiding the warranty and potential bricking are also covered.
The document discusses different approaches to detecting system compromise, including looking for rootkit side effects, signature-based scanning, and explicit compromise detection. It argues that modern malware need not use traditional rootkit techniques like hiding processes or sockets to achieve stealth. A demonstration of a "pretty stealthy backdoor" is presented that modifies only a few kernel data values without installing modules or hiding anything. The document proposes a classification of malware based on what operating system components it modifies and argues that type II malware modifying only data sections will be very difficult to detect.
This document discusses how hackers can break CI/CD infrastructure by exploiting vulnerabilities at different stages of the software development process. It outlines attacks such as inserting malware in source code or libraries, exploiting privileged access in build pipelines to achieve remote code execution, deploying zip bombs or memory bombs to crash systems, and compromising shared infrastructure between development and production environments. The document emphasizes the importance of limiting permissions, isolating networks, monitoring for anomalies, and hardening CI/CD systems with the same care as production servers.
There has been a Ransomware explosion the last 6 years and there have been very little done to stop infections aside from deprecated signature scans and classic malware scanner. Weston will go over a couple proof of concepts that work on even the most current versions of the malware stop from fully infecting the machines that would otherwise be infected with malware that demands 1000s of dollars in some instances. Weston will go over several methods of making your system immune to attacks from ransomware many of them were discovered from actually reverse engineering the malware early this year. Weston will also go over several open source tools to test your environments impact from malware such as Cryptowall and several tools both software and hardware that can protect your systems from malware infecting even methods of abusing the payment gateway system to allow you to get more than one file unlocked for free and Weston will also go into the research about breaking the encryption based on the outputted encrypted files.

Observability Concepts EVERY Developer Should Know -- DeveloperWeek Europe.pdfPaige Cruz
Monitoring and observability aren’t traditionally found in software curriculums and many of us cobble this knowledge together from whatever vendor or ecosystem we were first introduced to and whatever is a part of your current company’s observability stack.
While the dev and ops silo continues to crumble….many organizations still relegate monitoring & observability as the purview of ops, infra and SRE teams. This is a mistake - achieving a highly observable system requires collaboration up and down the stack.
I, a former op, would like to extend an invitation to all application developers to join the observability party will share these foundational concepts to build on:

HCL Notes and Domino License Cost Reduction in the World of DLAUpanagenda
Webinar Recording: https://www.panagenda.com/webinars/hcl-notes-and-domino-license-cost-reduction-in-the-world-of-dlau/
The introduction of DLAU and the CCB & CCX licensing model caused quite a stir in the HCL community. As a Notes and Domino customer, you may have faced challenges with unexpected user counts and license costs. You probably have questions on how this new licensing approach works and how to benefit from it. Most importantly, you likely have budget constraints and want to save money where possible. Don’t worry, we can help with all of this!
We’ll show you how to fix common misconfigurations that cause higher-than-expected user counts, and how to identify accounts which you can deactivate to save money. There are also frequent patterns that can cause unnecessary cost, like using a person document instead of a mail-in for shared mailboxes. We’ll provide examples and solutions for those as well. And naturally we’ll explain the new licensing model.
Join HCL Ambassador Marc Thomas in this webinar with a special guest appearance from Franz Walder. It will give you the tools and know-how to stay on top of what is going on with Domino licensing. You will be able lower your cost through an optimized configuration and keep it low going forward.
These topics will be covered
- Reducing license cost by finding and fixing misconfigurations and superfluous accounts
- How do CCB and CCX licenses really work?
- Understanding the DLAU tool and how to best utilize it
- Tips for common problem areas, like team mailboxes, functional/test users, etc
- Practical examples and best practices to implement right away
Removing Uninteresting Bytes in Software FuzzingAftab Hussain
Imagine a world where software fuzzing, the process of mutating bytes in test seeds to uncover hidden and erroneous program behaviors, becomes faster and more effective. A lot depends on the initial seeds, which can significantly dictate the trajectory of a fuzzing campaign, particularly in terms of how long it takes to uncover interesting behaviour in your code. We introduce DIAR, a technique designed to speedup fuzzing campaigns by pinpointing and eliminating those uninteresting bytes in the seeds. Picture this: instead of wasting valuable resources on meaningless mutations in large, bloated seeds, DIAR removes the unnecessary bytes, streamlining the entire process.
In this work, we equipped AFL, a popular fuzzer, with DIAR and examined two critical Linux libraries -- Libxml's xmllint, a tool for parsing xml documents, and Binutil's readelf, an essential debugging and security analysis command-line tool used to display detailed information about ELF (Executable and Linkable Format). Our preliminary results show that AFL+DIAR does not only discover new paths more quickly but also achieves higher coverage overall. This work thus showcases how starting with lean and optimized seeds can lead to faster, more comprehensive fuzzing campaigns -- and DIAR helps you find such seeds.

2. $whoami
• Certified android developer(udemy)
• 2nd year UIT RGPV student
• Member of juliar foundation
• can code in Java, python, juliar, c
• L33t at cybrary.it
3. What to expect
• Who are shadowbroker?
• What did they do?
• Brief intro to lost in translation(5th leak)
• Playing with fuzzbunch and danderspritz
• Clever ways these tools are being used now
4. Who are shadowbroker?
• A hacker group they published some National
Security Agency (NSA)'s equation group
hacking tools.
• First appeared in mid of august 2016
• However I have found reasons to believe that
its just 2 people who use to work for nsa as a
private contractor.
5. How did they do it?
1. They found creators of stuxnet , flame
kaspersky called themselves Equation Group
2. They followed Equation Group traffic
3. They found Equation Group source
4. We find many many Equation Group cyber
weapons
They explained the attack in layman's
terms -
8. Final leak “Lost in Translation”
• windows: contains Windows exploits,
implants and payloads
• swift: contains operational notes from
banking attacks, docs, excel files, ppt of some
attacks
• oddjob: is an implant builder that can deliver
exploits for Windows 2000 and later. Key
feature is that it is fully undetectable (FUD)
9. These nsa exploits can target cisco Firewalls,
Windows OS, Windows Server, Solaris boxes
running versions 6 to 10, RedHat 7.0,
15. Danderspritz
• Java-Based console from which compromised
computers can be managed.
• So Basically it’s a Remote Administration
tool(RAT).
• I have used it to make malicious dll files,
control the PeddleCheap / ExpandingPulley
implant.
19. What are we exploiting?
• The Server Message Block (SMB) protocol
• It is a network file sharing protocol(practically
used for storing configuration file of virtual
machine)
• CERTCC released information on a Server
Message Block (SMB) vulnerability affecting
Microsoft Windows
• Fuzzbunch uses this vulnerability to install
backdoor, inject dll, inject shellcode, etc
20. How we are going to do?
1. Make malicious dll with danderspritz.
2. Use eternalblue(special) to make backdoor.
3. Use doublepulsar(payload) to inject dll.
4. Use Danderspritz to listen to connections
21. For the demo we have 1 attacker machine and 1
victim
1. Windows 7 attacker
2. Windows 7 victim
23. Clever ways these exploits are used
1. Eternalblue without fuzzbunch
2. Making DoublePulsar and EternalBlue modules
Standalone like msfvenom
3. python script that uses EternalBlue to run
msfvenom output directly without ever installing
DoublePulsar
4. DoublePulsar detection script
5. Using Eternalblue in WannaCry v 2.0 ransomware
27. Wannacry ransomware
• First appeared on feb 2017
• Now there is a follow-up version which uses
the SMBv2 remote code execution
vulnerability
• Same vulnerability is used by eternalblue
• It encrypts with rsa-2048 encryption private
key is created then sent to attacker and then
gets deleted from the victim machine
30. Accidental hero finds a kill switch
• Problem with this is that attacker can change the domain
and reuse it
• So its not very effective
• However there are ways to find out the kill switch domain in
every sample
31. How to fix this issue
1. Installing security update MS17-010 windows
(best way)
2. Disable smb on your windows machine(ok way)
3. Blocking all incoming SMB traffic on port 445
4. Backup all your data in some external device
33. But they haven't given ms17-010 Security
update for some older version of windows.
So your best option is to use other 2 methods
34. 2.Disable smb on your windows
machine
• Go to control panel > Programs and features
• Go to turn ON/OFF windows features
• Uncheck the box SMB 1.0
35.
36. • However disabling smb protocol in not
recommended
• But its safer to do it when patches are not
available
• Blocking smb can only prevent the
ransomware from speading but patching
machine will make system resistant to attack
37. 3. Blocking all incoming SMB traffic
on port 445
Different wifi routers have interface but they
offer same functionality
• Go to 192.168.1.1
• Enter username password
• And find Application filter
40. What to do if already infected?
• Wait...
• Eventually someone will find a decryption
key(you get 7 days)
• If one machine is infected then take it offline
or block incoming SMB traffic on port 445 to
stop it from spreading
41. Should you pay the ransom?
• Well most users opt to pay
• Everytime a victim pays the malware creator
gets funded
• Some of this money is reinvested making
ramsomware smarter, more effective
• This is a vicious cycle
43. • Keeping in mind that prevention is better than
cure
• Install latest updates
• Make offline backup of all your data
• And lastly use your brain lol don’t just open
every attachment you get
