Tenable releases new version of Nessus that also runs on Raspberry Pi
Security firm Tenable has released version 10.0 of Nessus, a vulnerability scanner that is among the better known tools used to search for vulnerabilities on networked systems.
In a statement, the company said with this version, the number of supported platforms for Nessus had been extended to include the Raspberry Pi.
Nessus works by testing out each port on a system, determining what service it is running and then testing the service to see if it is a vulnerable version.

Book Review: Bug Bounty Bootcamp · System Overlord
Bug Bounty Bootcamp (Amazon, No Starch Press) by Vickie Li is one of No Starch Press’s newest offerings in the security space. The alliterative title is also the best three word summary I could possibly offer of the book – it is clearly focused on getting the reader into a position to participate in Bug Bounties from the first page to the last. This differentiates this book well against other web security books, despite covering many of the same vulnerabilities.
[...]
The first couple of chapters provide an introduction to the Bug Bounty space, helping the reader to understand the role of bounties in the overall security program of a company, selecting a bounty to participate in, and how the programs are managed in different situations. It also does a fairly good job of setting expectations for new bounty participants, but I think it might be a little bit on the optimistic side for some that are newer to the space.

Cracker Hackers Having a Field Day With GitLab Vulnerability
Anybody running on-premise GitLab servers need to patch for CVE-2021-22205, an exploit that was discovered in April, and which GitLab patched on April 14.
Evidently a lot of people didn’t get the message to install the fix, which is unfortunate because the vulnerability is being exploited in the wild.
According to the headline on one security website: “Tens of thousands unpatched GitLab servers under attack.” Another website says that black hats are taking advantage of the vulnerability to launch distributed denial of service attacks exceeding 1 Tbps.
