Go Malware is Now Common, Having Been Adopted by Both APTs and E-crime Groups

'The number of malware strains coded in the Go programming language has seen a sharp increase of around 2,000% over the last few years, since 2017, cybersecurity firm Intezer said in a report published recently. From a report: The company's findings highlight and confirm a general trend in the malware ecosystem, where malware authors have slowly moved away from C and C++ to Go, a programming language developed and launched by Google in 2007. While the first Go-based malware was detected in 2012, it took, however, a few years for Golang to catch on with the malware scene. "Before 2019, spotting malware written in Go was more a rare occurrence and during 2019 it became a daily occurrence," Intezer said in its report. But in the new report, Golang (as it's often also referred to instead of Go) has broken through and has been widely adopted. It is used by nation-state hacking groups (also known as APTs), cybercrime operators, and even security teams alike, who often used it to create penetration-testing toolkits.' -- source: https://it.slashdot.org/story/21/03/01/1545257 Cheers, Peter -- Peter Reutemann Dept. of Computer Science University of Waikato, NZ +64 (7) 577-5304 http://www.cms.waikato.ac.nz/~fracpete/ http://www.data-mining.co.nz/

First Fully Weaponized Spectre Exploit Discovered Online

'Catalin Cimpanu, reporting for The Record: A fully weaponized exploit for the Spectre CPU vulnerability was uploaded on the malware-scanning website VirusTotal last month, marking the first time a working exploit capable of doing actual damage has entered the public domain. The exploit was discovered by French security researcher Julien Voisin. It targets Spectre, a major vulnerability that was disclosed in January 2018. [...] The vulnerability, which won a Pwnie Award in 2018 for one of the best security bug discoveries of the year, was considered a milestone moment in the evolution and history of the modern CPU. Its discovery, along with the Meltdown bug, effectively forced CPU vendors to rethink their approach to designing processors, making it clear that they cannot focus on performance alone, to the detriment of data security. Software patches were released at the time, but the Meltdown and Spectre disclosures forced Intel to rethink its entire approach to CPU designs going forward. At the time, the teams behind the Meltdown and Spectre bugs published their work in the form of research papers and some trivial proof-of-concept code to prove their attacks. Shortly after the Meltdown and Spectre publications, experts at AV-TEST, Fortinet, and Minerva Labs spotted a spike in VirusTotal uploads for both CPU bugs. While initially there was a fear that malware authors might be experimenting with the two bugs as a way to steal data from targeted systems, the exploits were classified as harmless variations of the public PoC code published by the Meltdown and Spectre researchers and no evidence was found of in-the-wild attacks. But today, Voisin said he discovered new Spectre exploits -- one for Windows and one for Linux -- different from the ones before. In particular, Voisin said he found a Linux Spectre exploit capable of dumping the contents of /etc/shadow, a Linux file that stores details on OS user accounts.' -- source: https://it.slashdot.org/story/21/03/01/1851240 Cheers, Peter -- Peter Reutemann Dept. of Computer Science University of Waikato, NZ +64 (7) 577-5304 http://www.cms.waikato.ac.nz/~fracpete/ http://www.data-mining.co.nz/

Linux Mint Developers Will Force Updates on Users Like Microsoft Does with Windows 10
by Peter Reutemann 02 Mar '21

'Last month, the Linux Mint team published a post on the organization's official blog about the importance of installing security updates on machines running the Linux distribution. The essence of the post was that a sizeable number of Linux Mint devices was running outdated applications, packages or even an outdated version of the operating system itself. A sizeable number of devices run on Linux Mint 17.x, according to the blog post, a version of Linux Mint that reached end of support in April 2019. A new blog post, published yesterday, provides information on how the team plans to reduce the update reluctance of Linux Mint users. Next to showing reminders to users, Linux Mint's Update Manager may enforce some of the updates according to the blog post. "In some cases the Update Manager will be able to remind you to apply updates. In a few of them it might even insist." Upcoming versions will provide information on the implementation, how the "insisting" part may look like, and whether the installation of updates will be enforced. All of this boils down to a single question: how far should operating system developers go when it comes to updates? BetaNews adds: "And now, it seems the Linux Mint developers are taking a page out of Microsoft's playbook by planning to force some updates on its users. Yes, folks, Linux Mint is becoming more like Windows 10."' -- source: https://linux.slashdot.org/story/21/03/01/2032216 Cheers, Peter -- Peter Reutemann Dept. of Computer Science University of Waikato, NZ +64 (7) 577-5304 http://www.cms.waikato.ac.nz/~fracpete/ http://www.data-mining.co.nz/
