We all know the adage:
It is not a question of "IF" you will be hacked, but "WHEN".
This is true for all companies in all industries.
The ultimate answer to this problem is, to quote a famous French film:
"What is important is not the fall, but the landing." (*)
However, when speaking to upper management about cyber risks and the cost to implement remediation or prevention security controls, the answer we often get is a "Don't worry, we will be fine. We can just operate manually with pen and paper until we fix everything again”.
It might be true for (very few) companies, but the reality is unfortunately often much more complicated than that.
A recent example is a cyber-attack that occurred in the Indian Ocean region this week:
Leal Réunion, a car dealership on the Réunion island, got attacked by a hacker group.
This attack is impacting their ability to use their IT systems and some sensitive financial informati...

BUGS Package updated to version 4.1.3
#144 - Posted on
23 March 2022 - Author: SM - Category: Cryptography
Following our renewal support for the BUGS cryptography project, it came to our attention there was some compiling issues on newer linux systems (i.e.: the latest version of Debian/Kali Linux)
This is due to a change in GCC where the default behaviour related to global variable is stricter. Therefore, we have updated the BUGS Unix package to version 4.1.3 and it can now be compiled on newer Linux systems.
You can download it from our local BUGS Download page
Or it can also be downloaded from our GITHUB project page

Log4j vulnerability information and 4x steps to prioritise
#142 - Posted on
14 December 2021 - Author: SM - Category: Security
The aim of this article is to provide some core information about the log4j vulnerability which has been generating a lot of noise in the last few days as well as a list of 4x steps we are recommending based on advice from government agencies and security groups we are a member of.
This vulnerability is serious as it affects a very wide range of devices (CISCO, Checkpoint etc) and applications/services (Vmware vcenter, Apache based website, sentinel one, etc).
It has a CVSS score of 10/10 (critical), the worse possible and allows unauthenticated remote code execution: CVE-2021-44228
The vulnerability affects applications running all versions of log4j before version 2.15.0 and is exploited by sending a specific text string that is interpreted by the log4j library
The Cybersecurity & Infrastructure Security Agency (CISA) has issued some guidance about it: ...

The WhatsApp Privacy Question
#140 - Posted on
27 January 2021 - Author: SM - Category: Cryptography, Security
With Facebook recently changing its terms and privacy policy for all its WhatsApp users outside of the EU, it seems to have made a lot of people angry.
When it comes to (your) data privacy and what this update means to non-EU WhatsApp’s users, in the end, I believe it does not mean much difference to what existed before! and if you are ok with targeted Marketing then there is no need to do anything different.
Facebook/WhatsApp just put the spotlight on how personal information is being crossed reference and used for marketing purposes. It happened before but it seems more people this time around are more receptive about the implication of such practice and thus it is creating a wave of exode to over more privacy conscious messaging platforms.
Let's ask ourselves 3x basic questions about this situation:
1. What can WhatsApp see now?
WhatsApp cannot see the content of the messages sent through its platform (allegedly, but let’s assume t...

HOW TO PROTECT AGAINST THE NEW PHISHING ATTACKS GETTING AROUND MFA (CONSENT PHISHING)
#138 - Posted on
20 August 2020 - Author: SM - Category: Security, Hacking
There is a growing type of phishing attack which has been quite successful since the beginning of 2020, it is called a "Consent Phishing"
Traditional email phishing attacks will try to get the victim's credentials through a dangerous URL with a fake login webpage, a malware attachment or some other clever social engineering tactics.
Hopefully companies have some anti-phishing tools/technology to detect and protect them against most of those type of emails (some always manage to get through, no matter what technology you use and what vendors promise you!)
However, there is a new type of phishing attacks that leverages the OAuth authorisation framework used by some applications to access your account. Basically, there are a lot of legitimate applications that will request access to your O365 account (it could also be another type of Cloud app provider) through the generation of an OAuth token, so they don't need to know (and store) your O365 password.

SOME CYBER INSURANCE CLAIMS IMPACTED BY COVID-19?
#137 - Posted on
29 April 2020 - Author: SM - Category: Security
Below is a link to an interesting article arguing that cyber insurance claims might be affected by the recent surge of working from home, and especially working from a personal computer/endpoint.
DARKREADING ARTICLE
It opens up to a wider question as to whether or not the COVID-19 will have an impact on some (other) cyber insurance claims.
What we have seen from various online publications, specialised forums and discussions is a consensus towards the following answer: "probably not".
Taking into consideration what the above article is discussing, the answer is actually "probably not directly".
As companies/employees are setting up new ways of working, most of the time in a hurry, consideration of the potential impact on their cyber insurance is probably not at the top of their list.
One possible way to look at th...
