Metasploit Weekly Wrapup
Weekly Metasploit Wrapup: 2/23/17
I gave at the office
The office can be a popular place when it comes to giving. From selling kids'
cookies/candy to raising awareness for a charity, the opportunity to 'give at
the office' is definitely a thing. And now, thanks to Office macros, Metasploit
offers a new way to give (and receive!) at 'the Office'.
These days, using malicious macros in office productivity programs is still a
common attack vector. Designed with a handful of word-processing programs in
mind (including some open sour

Comparing and Modifying Objects in React
A central feature of the React framework is
that a component will re-render when its properties change. Additional action,
or deliberate inaction, can also be taken on a change of properties using
componentWillRecieveProps() -- at which point you’ll do your own comparison of
the new and old props. In both cases, if the two properties in question are
objects, the comparison is not so straightforward.How do I easily modify and

The CIS Critical Security Controls Explained - Control 2: Inventory and Control of Software Assets
As I mentioned in our last post, the 20 critical controls
are divided
into Basic, Foundational, and Organizational families in order to simplify
analysis and implementation. This also allows partial implementation of the
controls by security program developers who aren't building a program from
scratch, but want to apply all 20 of the controls. The first two controls of the
Center for Internet Security's (CIS) Critical Controls are

Incident Investigation: It's All About Context
When security operations centers or security teams have data output from our
security devices or from threat intelligence sources, it all too often lacks any
sort of reasonable context on which to base an investigation.
When we have Indicators of Compromise (IoCs) that define a particular type of
attack, often largely IP addresses and file hashes, this can make a very
difficult starting place; inefficient at best, paralyzing at worst. Data with no
intelligence lacks context and we need context

Maintaining information sharing balance
Cybersecurity information sharing issues are a hot topic. This is because a
balance must be maintained between benefits and risks of information sharing.
This balance is sometimes hard to maintain, and at the same time there are
currently legal requirements regarding sharing such information.
The main benefit of sharing cybersecurity information is more effective:
* incident prevention and
* incident response.
The main risks of sharing cybersecurity i

Suricata Overview
Synopsis:
Suricata is an open source threat detection engine that was developed by the
Open Information Security Foundation (OISF). The Beta was released at the end of
2009, with the standard version coming out in the middle of 2010. Suricata can
act as an intrusion detection system (IDS), and intrusion prevention system
(IPS), or be used for network security monitoring. It was developed alongside
the community to help simplify security processes. As a free and robust tool,
Suricata monitors ne

The Team Cymru Malware Hash Registry
Synopsis:
Team Cymru’s Malware Hash Registry (MHR) is a useful tool for scanning
suspicious files. It is free for private use and provides an excellent addition
to a comprehensive security plan. It scans the hash of a file against a number
of anti-virus packages and then lets you know if the file has previously been
detected as malware.
Who Are Team Cymru?
Team Cymru is an internet security research group that operate out of Illinois
as a non-profit organization. Cymru is pronounced Kum-ree, wh

February 2017 Patch Tuesday: Delayed
Earlier today Microsoft announced
that they will be delaying this month's security updates due to finding a
last-minute issue that could "impact some customers." This may be due to a
glitch in their new process
that they were not able to iron out in time for today's planned release.

How to Configure a Basic IPsec Tunnel
Synopsis
I recently started the blog under the tag IPsec. Anyone having background in
this regard would know that this topic is too elaborate to be covered with a
single article. I will be doing a series of articles to touch as many details as
I can. But first things first: you need to know about the basics of IPsec. I
would like to share with you a way to configure an IPsec tunnel under main mode.

Understanding GRE (2/2)
Synopsis:
In the last post , I talked about the GRE
tunnels, it’s Class of Service and the Firewall Filters it offers. The next
step is to learn about the simplest way to configure a tunnel between two sites
using GRE. This article aims to give understanding about the Configuration of
GRE Tunnels for Juniper Networks.
Pre-requisites:
