  1. 1. Jailbreak or Jail – Is Hacking for the Government A Crime? - Did they violate the CFAA, copyright laws, or both? - "Maybe. In fact, the U.S. Supreme Court is currently considering a case that will help clarify whether accessing a database you are allowed to access, but for a purpose for which you are not authorized, constitutes a violation of the statute. When Azimuth “cracked” the iPhone, they probably violated something in the license agreement. I have no earthly clue, because, frankly, the license agreement is unreadable. In fact, that’s kind of the point."
  2. 2. Penetration testing leaving organizations with too many blind spots - Pen tests don't test everything, do you still need them? - "surveyed enterprises with 3,000 or more employees and found that 70 percent of organizations perform penetration tests as a way to measure their security posture and 69 percent to prevent breaches, yet only 38 percent test more than half of their attack surface annually. Many organizations are conducting penetration tests to detect and mitigate threats yet remain dangerously vulnerable. The research shows that when using penetration testing as a security practice organizations lack visibility over their internet-exposed assets, resulting in blind spots that are vulnerable to exploits and compromise."
  3. 3. MythBusters: What pentesting is (and what it is not) – Help Net Security - Same source, different take: "During pentests, highly technical and skilled individuals manually vet results to identify risks via exploitation attempts and vulnerability chaining. Scanning for vulnerabilities and penetration testing are both necessary components of a comprehensive security strategy. One does not replace the other."
  4. 4. How to Conduct Vulnerability Assessments: An Essential Guide for 2021 - "A vulnerability scan provides a point-in-time snapshot of the vulnerabilities present in an organization's digital infrastructure. However, new deployments, configuration changes, newly discovered vulnerabilities, and other factors can quickly make the organization vulnerable again. For this reason, you must make vulnerability management a continuous process rather than a one-time exercise."
  5. 5. Identifying People Through Lack of Cell Phone Use – Schneier on Security
  6. 6. Zero-Knowledge Proofs (ZKPs) for vulnerability disclosure
  7. 7. A New PHP Composer Bug Could Enable Widespread Supply-Chain Attacks - "Composer is billed as a tool for dependency management in PHP, enabling easy installation of packages relevant to a project. It also allows users to install PHP applications that are available on Packagist, a repository that aggregates all public PHP packages installable with Composer. According to SonarSource, the vulnerability stems from the way package source download URLs are handled, potentially leading to a scenario where an adversary could trigger remote command injection. As proof of this behavior, the researchers exploited the argument injection flaw to craft a malicious Mercurial repository URL that takes advantage of its "alias" option to execute a shell command of the attacker's choice."
  8. 8. ISC Releases Security Advisory for BIND - "GSS-TSIG is an extension to the TSIG protocol which is intended to support the secure exchange of keys for use in verifying the authenticity of communications between parties on a network. SPNEGO is a negotiation mechanism used by GSSAPI, the application protocol interface for GSS-TSIG. The SPNEGO implementation used by BIND has been found to be vulnerable to a buffer overflow attack."
  9. 9. Apple AirDrop Vulnerability Exposes Users’ Personal Information - Vuln 1 - "After collecting the (hashed) contact identifiers, the attacker can recover phone numbers and email addresses offline. As shown in prior work, recovering phone numbers is possible in the order of milliseconds. Recovering email addresses is less trivial but possible via dictionary attacks that check common email formats such as [email protected]{gmail.com,yahoo.com,…}." and vuln 2 - "Importantly, the malicious sender does not have to know the receiver: A popular person within a certain context (e.g., the manager of a company) can exploit this design flaw to learn all (private) contact identifiers of other people who have the popular person in their address book (e.g., employees of the company)."
  10. 10. CISA Releases ICS Advisory on Real-Time Operating System Vulnerabilities - Quite the list of RTOSes! Samsung TVs, ICS gear with VxWorks, wow... Bob may have to go find these exploits (There are many).
  11. 11. An issue in the Linux Kernel could allow the hack of your system - “TALOS-2020-1211 (CVE-2020-28588) is an information disclosure vulnerability that could allow an attacker to view Kernel stack memory . We first discovered this issue on an Azure Sphere device (version 20.10), a 32-bit ARM device that runs a patched Linux kernel.”
