Ransomware: Develop and Test Your Response Strategy Using Simulation

Ransomware: Develop and Test your Response Strategy Using Simulation In this blog I want to take a look at Simulating a Ransomware Attack and how you would go about developing and testing a Response Strategy. I’ve already covered the basics of a Ransomware attack in this blog article: https://elasticito.com/ransomware-do-you-have-a-tried-and-tested-strategy-in-place/ The object of this exercise is twofold: Maintain business continuity – or in other words a ransomware attack should have little to no disruption to business; Contain and eliminate the attack quickly with minimal effort; Throughout this blog I am going to focus on behaviour rather than specific IoCs. Please also note that the information provide here is a high-level guide and not an exhaustive task list and is focused on the endpoint only. In a future blog post I will cover network security controls. While User Awareness Training is recommended is hasn’t been included as part of validating security controls.

Ransomware: Do you have a tried and tested strategy in place?

Ransomware: Do you have a tried and tested strategy in place? With the recent Garmin outage that is still ongoing, which has allegedly been caused by a Ransomware attack, a large number of Executives are going to be asking tough questions about how Ransomware could impact their own organisations, as there is a good chance that this outage has had a direct effect on their daily lives. TL:DR – Ransomware attacks are preventable, however organisations need to have a tried and tested strategy in place to prevent these attacks. Breach and Attack Simulation provides the visibility needed to develop and test a Ransomware prevention strategy. While my intention with this article is not to speculate on the Garmin outage specifically, the points below are important factors that YOUR business should consider as important attributes of your Cyber Incident Response Protocol. Due to a lack of transparent communication with their clients

How to Test your Security Controls for Resilience to Australian Cyber Security Centre (ACSC) Advisory 2020-008: Copy-paste Compromises

How to Test your Security Controls for Resilience to Australian Cyber Security Centre (ACSC) Advisory 2020-008: Copy-paste Compromises In conjunction with an announcement by the Australian Prime Minster, Scott Morrison, on National Television, the Australian Cyber Security Centre (ACSC) recently published an advisory (Advisory 2020-008: Copy-paste compromises) giving the MITRE Tactics, Techniques and Procedures (TTPs) used against multiple Australian organisations seen in recent campaigns by a sophisticated threat actor.   The title “Copy-paste compromises” is derived from the actor’s heavy use of tools copied almost identically from open source. One of the ACSC recommendation is that:   “It is imperative that Australian organisations are alert to this threat and take steps to enhance the resilience of their networks.”   And while the Advisory also recommends the following:   Prompt patching of internet-facing software, operating systems and devices Use of multi-factor authentication across all remote access services Implementing the remainder of the

How to Protect Your Customers and Your Brand from Stolen Credential Misuse

How to Protect Your Customers and Your Brand from Stolen Credential Misuse During 2020 a number of Online Retailers have made headline news due to the media erroneously reporting that their customer Portals had been breached. These include Tesco Clubcard Members (https://www.techradar.com/uk/news/tesco-clubcard-holders-warned-of-major-security-issue) and most recently, Wiggle (https://cyclingindustry.news/security-breach-reported-on-wiggles-customer-accounts). In both these instances there was no exploitation of a cyber vulnerability. Threat Actors in all likelihood gained access to these Portals Accounts using a database of credentials stolen from other platforms or possibly via a Spear Phishing campaign.    The obvious questions here are: How was this possible? and How can this be prevented in the future? I prefer a shared responsibility model so let’s answer the above questions with this in mind:   How was this possible? Many subscribers have the same username (email address) and password for all online portals and web applications. Therefore, if one Portal account is compromised,

Regularly Validating Security Controls with Breach and Attack Simulation

Regularly Validating Security Controls with Breach and Attack Simulation   Validating Security Controls is of vital importance for all organisations and is mandated by Cyber Security Frameworks like National Institute of Standards and Technology (N.I.S.T.) who offer a simple high-level way to do this using 5 steps:   IDENTIFY (CROWN JEWELS) PROTECT DETECT RESPOND RECOVER   To emphasise the importance of validating Security Control on a regular basis think of pilots doing a pre-flight check and inspection of their aircraft. Not performing these checks and inspections could lead to a loss of license for the pilots and the airline as it is mandatory and so should validating your organisation’s Security Controls. Simplistically you start by Identifying a Crown Jewel which could be an Endpoint, A Domain Controller or a Business Application. The next step is to detail and understand the attack vectors, which could be infiltration via email or a

You Should Adopt a Cyber Security Framework – Here’s Why

You Should Adopt a Cyber Security Framework – Here’s Why Today, cyber attacks and cyber security breaches are constantly happening around the world. These attacks are also continuously evolving, becoming more sophisticated and unforeseen. This makes it difficult for organisations to proactively prevent phising, malware and ransomware attacks. So what can your organisation do to become resilient to cyber threats? A suitable cyber security framework and cyber security policies and procedures can reinforce your organisation’s IT security.       Cyber Security Framework A growing number of organisations are coming to the realisation that their extensive investment in cyber security technologies has not provided the resilience to cyber attacks that they were expecting and are looking for answers as to why they are still susceptible to phishing, ransomware and malware. The answer to this susceptibility conundrum lies in the understanding and adoption of a Cyber Security Framework (CSF). This doesn't mean that blindly adopting

Why use the FAIR Model to quantify Cyber Risk for 3rd parties?

Why use the FAIR Model to quantify Cyber Risk for 3rd parties? Historically, questionnaires and or risk scoring have been the traditional tools used to evaluate the risk a 3rd party poses to an organisation. The Findings from questionnaires and risk scoring are often incredibly technical and complicated and are generally presented in heatmap style – red, orange, yellow, green – accompanied by a score and or letter grade, which aren't very useful in quantifying Risk to the business. To understand what the FAIR Model has to offer, let us first look at what we need to articulate to the Board or C-Level. In simplistic terms let’s begin by considering what Risk a 3rd Party could pose to an organisation if they were to share 2,000 data records with them. The Board or C-Level wants to know in financial terms what the cost to business will be if the 3rd Party is breached
