Processor Vulnerability – Spectre

by

0

Spectre breaks the isolation between different applications. It allows an attacker to trick error-free programs, which follow best practices, into leaking their secrets. In fact, the safety checks of said best practices actually increase the attack surface and may make applications more susceptible to Spectre

Spectre is harder to exploit than Meltdown, but it is also harder to mitigate.

Microsoft has issued a patch for Windows 10, while other versions of Windows are expected to be patched on the traditional Patch Tuesday on January 9, 2018. Microsoft has also issued a guidance document for mitigations on client devices. Please note that the patches released by Microsoft may be incompatible with certain antivirus software.

MacOS 10.13.2 mitigates some of the disclosed vulnerabilities, but MacOS 10.13.3 will enhance or complete these mitigations.

Processor Vulnerability – Meltdown

by

0

Meltdown breaks the most fundamental isolation between user applications and the operating system. This attack allows a program to access the memory, and thus also the secrets, of other programs and the operating system.

If your computer has a vulnerable processor and runs an unpatched operating system, it is not safe to work with sensitive information without the chance of leaking the information. This applies both to personal computers as well as cloud infrastructure.

Processors give the illusion of a sequence of instructions executed one-by-one. However, in order to most efficiently use cpu resources, modern superscalar processors actually begin executing many instructions in parallel. In cases where instructions depend on the result of previous instructions or checks which have not yet completed, execution happens based on guesses about what the outcome will be. If the guess is correct, execution has been sped up. If the guess is incorrect, partially-executed instructions are cancelled and architectural state changes (to registers, memory, and so on) reverted; but the whole process is no slower than if no guess had been made at all. This is sometimes called “speculative execution”.

Unfortunately, although architectural state is rolled back, there are other side effects, such as changes to TLB or cache state, which are not rolled back. These side effects can subsequently be detected by an attacker to determine information about what happened during the speculative execution phase. If an attacker can cause speculative execution to access sensitive memory areas, they may be able to infer what that sensitive memory contained.

There are three primary variants of the issue which differ in the way the speculative execution can be exploited. Variant CVE-2017-5754 relies on the fact that, on impacted microprocessors, during speculative execution of instruction permission faults, exception generation triggered by a faulting access is suppressed until the retirement of the whole instruction block. In a combination with the fact that memory accesses may populate the cache even when the block is being dropped and never committed (executed), an unprivileged local attacker could use this flaw to read privileged (kernel space) memory by conducting targeted cache side-channel attacks. Note: CVE-2017-5754 affects Intel x86-64 microprocessors. AMD x86-64 microprocessors are not affected by this issue.

krack attack scripts released

krack attack is a pseudonym for key reinstallation attacks. Krack attack uses a vulnerability in WPA2 (Wi-Fi Protected Access II ) handshake process. Wpa2 is used to protect communication of wireless devices. wpa2 has a mechanism that permits devices to join the network with a pre-shared password and a four-way handshake. The attack works against all modern protected Wi-Fi networks. The weaknesses are in the Wi-Fi standard itself, and not in individual products or implementations. Therefore, any correct implementation of WPA2 is likely affected.

According to Mathy Vanhoef, who discovered the flaw, threat actors can leverage the vulnerability to decrypt traffic, hijack connections, perform man-in-the-middle attacks, and eavesdrop on communication sent from a WPA2-enabled device.

Scripts to perform krack attack has released on GitHub.

You can find scripts here.

Cyberprobe open source real time monitoring SIEM

by

0

The Cyberprobe project is an open-source distributed architecture for real-time monitoring of networks against attack. The software consists of two components:

a probe, which collects data packets and forwards it over a network in standard streaming protocols.
a monitor, which receives the streamed packets, decodes the protocols, and interprets the information.
These components can be used together or separately. For a simple configuration, they can be run on the same host, for more complex environments, a number of probes can feed a single monitor.

The probe, cyberprobe has the following features:

The probe can be tasked to collect packets from an interface and forward any which match a configurable address list.
The probe can be configured to receive Snort alerts. In this configuration, when an alert is received from Snort, the IP source address associated with the alert is dynamically targeted for a period of time. In such a configuration, the system will collect data from any network actor who triggers a snort rule and is thus identified as a potential attacker.
The probe can optionally run a management interface which allows remote interrogation of the state, and alteration of the configuration. This allows dynamic alteration of the targeting map, and integration with other systems.
The probe can be configured to deliver on one of two standard stream protocols.

The monitor tool, cybermon has the following features:

Collects packets delivered in stream protocols.
Decodes packet protocols in and raises events in near-real-time.
Decoded information is made available to user-configurable logic to define how the decoded data is handled. A simple configuration language is used (LUA) and example configurations are provided to monitor data volumes, display data hexdumps, or stash the data in files.
Packet forgery techniques are included, which allow resetting TCP connections, and forging DNS responses. This can be invoked from your LUA in order to fight back against attacks on your network.
Has a pub/sub delivery mechanism with subscribers for ElasticSearch, Google BigQuery and Gaffer graph store.
Supports IP, TCP, UDP, ICMP, HTTP and DNS protocols, currently.

The cybermon software includes some support for STIX as a threat indicator specification, and can create alerts on the presence of threats on the network.

The code is targeted at the Linux platform, although it is generic enough to be applicable to other UN*X-like platforms.

rapid7/ metasploitable3 – a VM for metasploit.

by

metasploitable3

Metasploitable3 is a VM that is built from the ground up with a large amount of security vulnerabilities. It is intended to be used as a target for testing exploits with metasploit.

Metasploitable3 is released under a BSD-style license. See COPYING for more details.
Building Metasploitable 3

System Requirements:

OS capable of running all of the required applications listed below
VT-x/AMD-V Supported Processor recommended
65 GB Available space on drive
4.5 GB RAM

Requirements:

Packer
Vagrant
Vagrant Reload Plugin
VirtualBox
Internet connection

NOTE: A bug was recently discovered in VirtualBox 5.1.8 that is breaking provisioning. More information here.

NOTE: A bug was recently discovered in Vagrant 1.8.7 on OSX that is breaking provisioning. More information here.

To build automatically:

Run the build_win2008.sh script if using bash, or build_win2008.ps1 if using Windows.
If the command completes successfully, run ‘vagrant up’.
When this process completes, you should be able to open the VM within VirtualBox and login. The default credentials are U: vagrant and P: vagrant.

To build manually:

Clone this repo and navigate to the main directory.
Build the base VM image by running packer build windows_2008_r2.json. This will take a while the first time you run it since it has to download the OS installation ISO.
After the base Vagrant box is created you need to add it to your Vagrant environment. This can be done with the command vagrant box add windows_2008_r2_virtualbox.box –name=metasploitable3.
Use vagrant plugin install vagrant-reload to install the reload vagrant provisioner if you haven’t already.
To start the VM, run the command vagrant up. This will start up the VM and run all of the installation and configuration scripts necessary to set everything up. This takes about 10 minutes.
Once this process completes, you can open up the VM within VirtualBox and login. The default credentials are U: vagrant and P: vagrant.
