In part one of this cyber resilience blog series, we discussed what it means to be a resilient organization. For part two, let’s discuss why organizations need to consider these challenges and who’s responsible for addressing them. Whilst asking why an organization may need to be resilient sounds a bit silly, I can say from experience that just because something seems obvious doesn’t mean it’s not quite a bit of work.
As hackers’ methods become more sophisticated, the scale of email security breaches and the frequency at which they occur grow greater with each passing year. In 2019 alone, an estimated 2 billion unique email addresses, accompanied by over 21 million unique passwords, were exposed within a single data breach.
For the majority of people in the information security world, the act of offensive hacking is something they are tasked with protecting against but have little ability to do themselves. That is like asking a professional boxer to enter the ring without knowing how to throw a punch. Sure, you may be able to get in and last a few rounds, but eventually, a formidable opponent will wear you down and knock you out.
Zero Trust is a security concept that is based on the notion that organizations should not take trust for granted, regardless of whether access attempts originate from inside or outside its perimeters. An enterprise needs to verify any attempt for connection to its systems before granting access. At the same time, the defensive layers that define the Zero Trust model should enable access for enterprise users no matter where they are and no matter what device they’re using.
Managing security incidents can be a stressful job. You are dealing with many questions all at once. What’s the scope? Who do I need to engage? How do I manage all of this? As an Incident Commander (IC), you have many responsibilities. You’re responsible for driving an incident to resolution as quickly as possible, creating the resources necessary to document, collaborate, and communicate while helping identify, engage, and orient the right people.
Historically, common detection methods have used file hashes (MD5, SHA1, and SHA256)—unique signatures based on the entire contents of the file—to identify malware. Modern threat actors have increased in sophistication to a point where every instance of a given malware will have a different hash, and that hash will vary from machine to machine.
As if Puerto Rico wasn’t having a hard enough time as it attempts to recover from a recession, the damage caused by devastating hurricanes in recent years, and a damaging earthquake last month, it now finds itself being exploited by cybercriminals. According to media reports, the government of the US island territory has lost more than US $2.6 million after falling for the type of email scam that has plagued companies and organisations around the world.
Post-exploitation can be one of the most time-consuming but worthwhile tasks that an offensive security professional engages in. Fundamentally, it is where you are able to demonstrate what an adversary may do if they compromise a business. A big component of this is trying to get as far as you can without alerting the defenders to what you’re doing.
Having worked with many individuals responding to incidents where their digital private images were shared without consent, social media or email accounts had unauthorised access, and even physical safety was a concern, it is all too familiar how terrifying the unknown can be. As someone who has been on both the victim’s and later the responder’s side, I am qualified to express both the terror and knowledge of things you can do to take back control.
