---------------------------------------------
I found a malicious Office document with VBA code where most of the identifiers (variables, function names, ...) consist solely out of characters that are not ASCII (.e.g, these characters have values between 128 and 255).

∗∗∗ An Analysis of a Discerning Phishing Website , (Fri, Jul 22nd) ∗∗∗
---------------------------------------------
Cybercriminals and adversaries have long used phishing websites to obtain credentials and access systems they usually would not have access to. Indeed, it could be more cost-effective than other methods, such as buying zero-day vulnerabilities and weaponizing them. I was alerted to a phishing attempt and requested further details. After doing some analysis, I observed several differences and technological improvements that the adversaries had made as compared to the usual phishing attempts.

∗∗∗ Cryptominers & WebAssembly in Website Malware ∗∗∗
---------------------------------------------
WebAssembly (also referred to as Wasm) is a binary instruction format that runs in the browser to enable high-performance applications on web pages and can be executed much faster than traditional JavaScript. WebAssembly can be executed in a variety of environments, including servers, IoT devices, and mobile or desktop apps — but was originally designed to run on the web.

∗∗∗ An Easier Way to Keep Old Python Code Healthy and Secure ∗∗∗
---------------------------------------------
Python has its pros and cons, but its nonetheless used extensively. For example, Python is frequently used in data crunching tasks even when there are more appropriate languages to choose from. Why? Well, Python is relatively easy to learn. Someone with a science background can pick up Python much more quickly than, say, C. However, Pythons inherent approachability also creates a couple of problems.

∗∗∗ Sh*Load Exploits (Episode V: Return of the Error) ∗∗∗
---------------------------------------------
Our first post in the Firmware Developers Need To Know blog series, Episode I: The Last Error, pointed out the benefits of adopting clean error codes. And then two weeks later, TLStorm, bam. Armis’ research engineers announced the discovery of three vulnerabilities in APC devices –the key problem – ignoring error codes! Unfortunately, little attention or thought is paid to error codes within firmware code (and many critical open source projects).

∗∗∗ PART 1: How I Met Your Beacon – Overview ∗∗∗
