We Have All Heard This Story Before It’s no doubt that ransomware is is the biggest threat in the modern cybersecurity landscape. The highest amount of ransom ever paid by a single company for a single incident is $40 million US dollars. Companies can incur millions more in remediation costs, service downtime, legal settlements, higher insurance premiums, and potentially suffer long-term deleterious effects to their brand reputation. Blockchain research group Chainalysis suggests that nearly $700 million USD in ransomware ransom was paid in 2020. Defenders have all been hearing this story for years, and know how to secure against ransomware right? The most common initial access vector is phishing so staff training sessions educating our staff on how to spot a deceptive url is required to keep the bad guys out. Installing endpoint security products and keeping them updated, and of course keep bulletproof backups right? Well, yes and no….

In this this series of articles and videos, I will explore some PHP malware code that has been publicly published. All the samples discussed are derived from a GitHub repository maintained by marcocesarato. The advice from Ripple Software Consulting is to always maintain solid web-server security through hardened configuration and monitoring, and vulnerability scanning both internal and external surfaces with a tool such as CISOfy’s Lynis or Greenbone’s GVM. For an example of solid LAMP stack server security you can visit the RSRC’s VPS Deploy WordPress GitHub repository which is a tool for automatically deploying a WordPress website on a hardened Linux VPS Server. If you don’t want to secure your own WordPress installation, you can hire a trained security consultant such as Ripple Software, or you can use another 3rd party managed hosting provider. PHP is a scripting language which means its source code is usually in human readable…

Linux Dominates Performance-based Computing Market Share Linux may be less susceptible to cyber-attacks because Windows presents such an attactive target by holding the majority of the desktop marketshare. However, Linux servers dominate the global market in some powerful ways. According to industry reports, Linux OSs comprise 100% of all supercomputers, and over 95% of the top 1 million web servers are running Linux. Linux runs on 90% of all cloud infrastructure and dominates the mobile phone market with > 80% of market share. Embedded operating systems, and RTOS for IoT devices? Again, Linux is by far the most popular OS of choice. If you want more interesting facts about Linux’s market presence, you can Read Nick Galov’s revealing 2021 comprehensive summary of Linux market penetration. Knowing how to conduct a Security Audit of a Linux system and services is very important indeed.  This most often includes whitelisting required applications and…

Building Your IT Security News Pipeline

If you are responsible for securing a network, you should know that monitoring reliable IT security news is now critical to mitigating threats on your precious goods. Prioritizing that news landscape and rolling out a timely response is also critical to a solid recipe for security. While it is not realistic to expect security architects to have that kind of response time, if you are ignoring IT security news, you  might need those backups you have been diligently maintaining or worse. Building a solid incoming information pipeline requires an analysis of the IT security news landscape.  The most fundamental elements of this landscape includes threat advisories & guidelines, updates to best-practices and standardization recommendations,  and changing legal requirements if they apply to your organizational assets. Threat analysis reports and newly released Common Vulnerability Exposure details (CVEs) are critical secondary elements that relay more detailed information about vulnerabilities affecting specific software. …
