  • Hackers Turn to OpenDocument Format to Avoid AV Detection

    Attackers have a new obfuscation technique that uses the OpenDocument file format for sneaking payloads past antivirus software.

    Past macro-based attacks have relied on malware hitching a ride with .docx, .zip, .jar and many other file formats. But researchers at Cisco Talos said that because these attempts are nearly certain to be red flagged by endpoint protection, hackers are turning to the OpenDocument (ODT) format to avoid detection.

    “The use of the ODT file format shows that actors are happy to try out different mechanisms of infection, perhaps in an attempt to see if… these documents have a higher rate of infection or are better at avoiding detection,” wrote Cisco Talos researchers Warren Mercer and Paul Rascagneres on Monday.

  • [Older] Danish hearing aid firm slashes forecasts after breach [iophk: Windows TCO]

    Demant, the maker of Oticon-branded hearing aids, explained in a statement issued late last week that it is still in the process of recovering from an unspecified “cyber incident” that occurred on September 3 and disrupted the manufacture and distribution of its products.

    The Danish firm responded to the attack by “shutting down IT systems across multiple sites and business units” in order to contain the problem. Even though it acted promptly, and data backup was largely intact, its business was nonetheless severely affected.

  • [Older] #1278700: Hearing aid manufacturer hit by cyber attack slashes profits by $95 million [iophk: Windows TCO]

    Details remain sketchy, but the fact that the company shut down IT systems across multiple sites and business units around the world – and that they claim this helped contained the problem – suggest that the firm’s systems were infected by malware, potentially ransomware.

  • [Older] Demant Group Companies Hit by Cyber Attack [iophk: Windows TCO]

    Companies in the Demant Group, which include hearing aid manufacturers Oticon, Sonic Innovations, and Bernafon, were the victims of a cyber attack that affected their IT infrastructure on September 3. The group was forced to shut down its IT systems across multiple sites and business units to contain the issue last week, causing some companies in the group to come to a virtual standstill relative to digital ordering and communications.

  • FDA warns of potential cyber vulnerabilities in internet-connected medical devices

    The vulnerabilities, referred to by the agency as URGENT/11, have the potential to harm operating systems for medical devices connected to communications networks like Wi-Fi and equipment such as routers and phones.

    According to the FDA, the cyber vulnerabilities could allow a remote actor to “take control” of the device, leading to a change in function, information leaks or causing the device to stop functioning

  • Malvertiser exploited Chrome and WebKit flaws to display over one billion dodgy ads

    According to researchers, malvertising campaigns by eGobbler typically last for a few days. In that period, eGobbler buys advertisements on genuine services but embeds malicious code in its adverts to perform unauthorised activity on users' browsers.

  • When LexisNexis Makes a Mistake, You Pay For It

    But consumer lawyers and privacy advocates worry the problem with mixed files and other data errors is likely to get worse. A Government Accountability Office report in 2013 noted "a vast increase" in the number and types of companies that collect and sell consumer data—often called data brokers—and suggested Congress consider stronger regulation of the industry, which includes LexisNexis. More than five years later, the regulatory landscape hasn't changed much, but the industry has continued to grow and evolve.

    These days, Rapp says, it's almost impossible to avoid being tracked by data brokers—not just LexisNexis. "If you have a pulse, you have a report," he says.

    Data brokers "operate in a legal vacuum" when it comes to many kinds of consumer data, says Lydia de la Torre, a data protection law professor at Santa Clara University who has worked with companies including eBay and PayPal on privacy issues. Although lawmakers have recently proposed a series of federal regulations to protect consumers from the industry, de la Torre isn't optimistic any will pass in the near term.

  • Decades-Old Code Is Putting Millions of Critical Devices at Risk

    Today Armis, the Department of Homeland Security, the Food and Drug Administration, and a broad swath of so-called real-time operating system and device companies disclosed that Urgent/11, a suite of network protocol bugs, exist in far more platforms than originally believed. The RTO systems are used in the always-on devices common to the industrial control or health care industries. And while they're distinct platforms, many of them incorporate the same decades-old networking code that leaves them vulnerable to denial of service attacks or even full takeovers. There are at least seven affected operating systems that run in countless IoT devices across the industry.

  • 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.
