  • Malvertisers [cracked] 120 ad servers to load malicious ads

    A malvertising operation known under the codename of Tag Barnakle has breached more than 120 ad servers over the past year and inserted malicious code into legitimate ads that redirected website visitors to sites promoting scams and malware.

    Security firm Confiant first reported on this campaign last year, in April 2020, when it said it found 60 ad servers that were left unpatched and compromised by the Tag Barnakle gang.

    One year later, Confiant said that despite exposing the group’s tactics and raising an alarm in the online advertising industry, the Tag Barnakle group has continued to operate unchecked and has doubled the number of servers it breached.

  • Senators introduce legislation to protect critical infrastructure against attack [iophk: Windows TCO]

    The National Risk Management Act would require the Cybersecurity and Infrastructure Security Agency (CISA) to conduct a five-year national risk management cycle. This would involve CISA identifying and compiling the major risks to critical infrastructure in a report sent to the president and Congress, with the president then detailing to Congress how the administration was tackling these threats.

  • Prometei Botnet Exploiting Unpatched Microsoft Exchange Servers

    Attackers are exploiting the ProxyLogon Microsoft Exchange Server flaws to co-opt vulnerable machines to a cryptocurrency botnet named Prometei, according to new research.

    "Prometei exploits the recently disclosed Microsoft Exchange vulnerabilities associated with the HAFNIUM attacks to penetrate the network for malware deployment, credential harvesting and more," Boston-based cybersecurity firm Cybereason said in an analysis summarizing its findings.

    First documented by Cisco Talos in July 2020, Prometei is a multi-modular botnet, with the actor behind the operation employing a wide range of specially-crafted tools and known exploits such as EternalBlue and BlueKeep to harvest credentials, laterally propagate across the network and "increase the amount of systems participating in its Monero-mining pool."

  • Hackers Use Prometei Botnet to Attack Microsoft Exchange Users [Ed: More Microsoft blame-shifting?]

    Cybercriminals are using the Prometei botnet to exploit Microsoft Exchange vulnerabilities CVE-2021-27065 and CVE-2021-26858, according to Cybereason. Both vulnerabilities have been linked to Hafnium, a state-sponsored threat actor used in Exchange Server attacks reported in March 2021.

  • “NAME:WRECK” Cybersecurity Vulnerability Highlights Importance of Newly Issued IoT Act

    A recently discovered security vulnerability potentially affecting at least 100 million Internet of Things (“IoT”) devices[1] highlights the importance of the newly enacted IoT Cybersecurity Improvement Act of 2020 (the “IoT Act”). Researchers at the security firms Forescout Research Labs and JSOF Research Labs have jointly published a report detailing a security vulnerability known as “NAME:WRECK.” This is exactly the type of issue that the new IoT Act was and is designed to address at the governmental level, because the vulnerability can detrimentally affect the security of millions of interconnected IoT devices. As our recent blog “New Internet of Things (IoT) Cybersecurity Law’s Far Reaching Impacts” discussed, this is the type of cybersecurity risk that all organizations should consider and factor in to their supply chain risk assessments and mitigation measures. If your organization directly uses IoT devices, or contracts with vendors who supply IoT devices or software/systems using IoT devices, whether in the healthcare, manufacturing, retail, financial services, hospitality or employment context, you should be evaluating your cybersecurity programs for protecting IoT devices.

  • Chrome HTTPS Update: Chrome 90 to Use HTTPS for Incomplete URLs

    Google Chrome version 90 will default to HTTPS for incomplete URLS. For example, Chrome will load “https://domain.com” when a user types “domain.com.” (And if the HTTPS fails because a site lacks SSL/TLS, it’ll revert to using HTTP.)

    It’s no secret that using HTTPS to serve up your website is faster and more secure than using the default HTTP protocol. And Google, recognizing that many browser users don’t type in complete URLs when accessing websites, decided to bridge the gap between user experience and security this year. Their latest browser update, version 90, is expected to use HTTPS by default when a user types in a website address without specifying the protocol.

    In reality, this is a logical move considering that the latest data from Google’s Transparency Report shows that 95% of sites across Google already use encryption to protect their traffic. But when and why are they implementing this update? Is Chrome forcing HTTPS? And what does this change mean for your website?

  • How to install go1.19beta on Ubuntu 22.04 – NextGenTips

    In this tutorial, we are going to explore how to install go on Ubuntu 22.04 Golang is an open-source programming language that is easy to learn and use. It is built-in concurrency and has a robust standard library. It is reliable, builds fast, and efficient software that scales fast. Its concurrency mechanisms make it easy to write programs that get the most out of multicore and networked machines, while its novel-type systems enable flexible and modular program constructions. Go compiles quickly to machine code and has the convenience of garbage collection and the power of run-time reflection. In this guide, we are going to learn how to install golang 1.19beta on Ubuntu 22.04. Go 1.19beta1 is not yet released. There is so much work in progress with all the documentation.

  • How To Install MongoDB on AlmaLinux 9 - idroot

    In this tutorial, we will show you how to install MongoDB on AlmaLinux 9. For those of you who didn’t know, MongoDB is a high-performance, highly scalable document-oriented NoSQL database. Unlike in SQL databases where data is stored in rows and columns inside tables, in MongoDB, data is structured in JSON-like format inside records which are referred to as documents. The open-source attribute of MongoDB as a database software makes it an ideal candidate for almost any database-related project. This article assumes you have at least basic knowledge of Linux, know how to use the shell, and most importantly, you host your site on your own VPS. The installation is quite simple and assumes you are running in the root account, if not you may need to add ‘sudo‘ to the commands to get root privileges. I will show you the step-by-step installation of the MongoDB NoSQL database on AlmaLinux 9. You can follow the same instructions for CentOS and Rocky Linux.

  • Self-host a Ghost Blog With Traefik

    Ghost is a very popular open-source content management system. Started as an alternative to WordPress and it went on to become an alternative to Substack by focusing on membership and newsletter. The creators of Ghost offer managed Pro hosting but it may not fit everyone's budget. Alternatively, you can self-host it on your own cloud servers. On Linux handbook, we already have a guide on deploying Ghost with Docker in a reverse proxy setup. Instead of Ngnix reverse proxy, you can also use another software called Traefik with Docker. It is a popular open-source cloud-native application proxy, API Gateway, Edge-router, and more. I use Traefik to secure my websites using an SSL certificate obtained from Let's Encrypt. Once deployed, Traefik can automatically manage your certificates and their renewals. In this tutorial, I'll share the necessary steps for deploying a Ghost blog with Docker and Traefik.
