This document discusses various techniques for evading antivirus, firewalls, and intrusion prevention systems (IPS). It begins with techniques for antivirus evasion using tools like msfvenom, veil-evasion, shellter, and unicorn to obfuscate payloads. Next it discusses firewall and IPS evasion techniques like stage encoding/encryption, zombie scanning, tunneling over protocols like ICMP, DNS, and using a custom Tor configuration. The document provides examples and links to demonstrate these evasion techniques.

(NET301) New Capabilities for Amazon Virtual Private CloudAmazon Web Services
?
Amazon's Virtual Private Cloud (Amazon VPC) continues to evolve with new capabilities and enhancements. These features give you increasingly greater isolation, control, and visibility at the all-important networking layer. In this session, we review some of the latest changes, discuss their value, and describe their use cases.
The document discusses new features in MySQL 5.6 replication including:
1) Crash-safe slaves that store replication information in database tables to prevent data loss if slaves crash.
2) Multi-threaded slaves that improve performance by distributing the replication workload across multiple threads.
3) Time-delayed replication that allows replication to be delayed by a configurable number of seconds.
4) Optimized row-based replication that reduces the size of binary logs by only replicating changed columns where possible.
Amazon Virtual Private Cloud (Amazon VPC) lets you provision a logically isolated section of the AWS cloud where you can launch AWS resources in a virtual network that you define. In this talk, we discuss advanced tasks in Amazon VPC, including the implementation of VPC peering, the creation of multiple network zones, the establishment of private connections, and the use of multiple routing tables. We also provide information for current Amazon EC2-Classic network customers and help you prepare to adopt Amazon VPC.
- The document discusses Neutron L3 HA (VRRP) and summarizes a presentation given on the topic.
- Neutron L3 HA uses the VRRP protocol to provide redundancy and failover for virtual routers across multiple network nodes. A heartbeat network is created for each tenant using their tenant network.
- When a router is created, a heartbeat port and interface are created on each L3 agent node using the tenant's heartbeat network to enable communication between the agents for the VRRP implementation.
This document discusses using plain Linux bridges for networking Docker containers on Kubernetes clusters deployed on OpenStack. It involves pre-allocating IP addresses on virtual machines, configuring Docker bridges to use the pre-allocated subnet, and allowing Kubernetes pods and containers to use the pre-allocated IP addresses for networking. The approach aims to provide a simple networking solution that is compatible with legacy systems.
The document summarizes a hacking attack on a company called mBank. The attack involved scanning the website for vulnerabilities, finding credentials in PHP files that allowed accessing the MySQL database, and uploading a PHP shell to gain remote access. Key steps included SQL injection to find files on the server, extracting credentials from the configuration file to access the database as the root user, and using the database to upload a web shell.
Web Services are the mechanism or the medium of communication through which two applications / machines will exchange the data/business services irrespective of their underline architecture and the technology.
The term REST comes from Roy Fielding's PhD dissertation, published in 2000, and it stands for REpresentational State Transfer. REST by itself is not an architecture; REST is a set of constraints that, when applied to the design of a system, creates a software architectural style. If we implement all the REST guidelines outlined in Fielding's work, we end up with a system that has specific roles for data, components, hyperlinks, communication protocols, and data consumers.
PuppetConf 2013 vCloud Hybrid Service and PuppetNan Liu
?
The document discusses automating the deployment of a VMware vCloud Hybrid Service (vCHS) using Puppet. It describes using Puppet to deploy and configure the various vCHS components through their respective APIs, including vCenter, vShield, and vCloud Director. It addresses challenges in automating these components and proposes treating everything as a "native resource" in Puppet and using "transport resources" to connect to the component APIs via SSH, vSphere API, vShield API, and vCloud Director API.
