Overview The Coronavirus 2019 (COVID-19) global pandemic has caused widespread fear of the unknown and deadly aspects of this novel virus, generated growth in certain industries to combat it, and created a shift toward remote work environments to slow the spread of the disease.  Defending Your Organization Against COVID-19 Cyber Attacks. In this webinar, AJ, and I describe COVID-19 attacks in January through March, the groups behind them, and key MITRE ATT&CK techniques being employed….

Cyber threats are so numerous that it’s impossible to prevent security incidents altogether. That’s why they organisations increasingly relying on cyber insurance policies to cover the costs when data breaches and cyber attacks occur. But just how helpful is cyber insurance? We take at a look at everything you need to know in this blog. What is cyber insurance? Cyber insurance is a specific type of protection, helping organisations mitigate the financial costs associated with…

Organisations are always looking for ways to improve their security practices, and one of the most effective ways to achieve this is by enrolling employees on cyber security training courses. A recent Lucy Security study found that 96% of respondents agreed that a greater level of awareness over cyber security threats contributed to overall improvements in their defences. Despite that, comparatively few provided adequate training to help staff mitigate the risks of data breaches and cyber…

Passwords. We need them for almost everything nowadays. Entering our phones, our computers, social media, and almost any website that involves a credit card purchase or includes personal details. Every time we start a new account on a password-protected site or system, we’re prompted to create a password. We’re usually urged to make it a strong one, sometimes even forced to make it (#$uPeR*) complicated, but oftentimes we’re always thinking one of two things: 1….

Detrimental lies are not new. Even misleading headlines and text can fool a reader.  However, the ability to alter reality has taken a leap forward with “deepfake” technology which allows for the creation of images and videos of real people saying and doing things they never said or did. Deep learning techniques are escalating the technology’s finesse, producing even more realistic content that is increasingly difficult to detect. Deepfakes began to gain attention when a…

The proof-of-concept shared with MAPP (Microsoft Active Protection Program) members is both extremely simple and perfectly reliable. It results in an immediate BSOD (Blue Screen of Death), but more so, indicates the likelihood of exploitation for those who can manage…

Securing documents before cloud Before the cloud, organizations would collaborate and store documents on desktop/laptop computers, email and file servers. Private cloud use-cases such accessing and storing documents on intranet web servers and network attached storage (NAS) improved the end-user’s experience. The security model followed a layered approach, where keeping this data safe was just as important as not allowing unauthorized individuals into the building or data center. This was followed by a directory service…
