KnowBe4 - Heart of the Matter: How LLMs Can Show Political Bias in Their Outputs

Image
Wired just published an interesting story about political bias that can show up in LLM's due to their training. It is becoming clear that training an LLM to exhibit a certain bias is relatively easy. This is a reason for concern, because this can "reinforce entire ideologies, worldviews, truths and untruths” which is what OpenAI has been warning about.  from KnowBe4 Security Awareness Training Blog https://blog.knowbe4.com/heart-of-the-matter-how-llms-can-show-political-bias-in-their-outputs

Schneier - Security Risks of AI

Stanford and Georgetown have a new report on the security risks of AI—particularly adversarial machine learning—based on a workshop they held on the topic. Jim Dempsey, one of the workshop organizers, wrote a blog post on the report: As a first step, our report recommends the inclusion of AI security concerns within the cybersecurity programs of developers and users. The understanding of how to secure AI systems, we concluded, lags far behind their widespread adoption. Many AI products are deployed without institutions fully understanding the security risks they pose. Organizations building or deploying AI models should incorporate AI concerns into their cybersecurity functions using a risk management framework that addresses security throughout the AI system life cycle. It will be necessary to grapple with the ways in which AI vulnerabilities are different from traditional cybersecurity bugs, but the starting point is to assume that AI security is a subset of cybersecurity and to

Schneier - AI to Aid Democracy

There’s good reason to fear that A.I. systems like ChatGPT and GPT4 will harm democracy. Public debate may be overwhelmed by industrial quantities of autogenerated argument. People might fall down political rabbit holes, taken in by superficially convincing bullshit, or obsessed by folies à deux relationships with machine personalities that don’t really exist. These risks may be the fallout of a world where businesses deploy poorly tested A.I. systems in a battle for market share, each hoping to establish a monopoly. But dystopia isn’t the only possible future. A.I. could advance the public good, not private profit, and bolster democracy instead of undermining it. That would require an A.I. not under the control of a large tech monopoly, but rather developed by government and available to all citizens. This public option is within reach if we want it. An A.I. built for public benefit could be tailor-made for those use cases where technology can best help democracy. It could plausib

Schneier - Cyberweapons Manufacturer QuaDream Shuts Down

Following a report on its activities , the Israeli spyware company QuaDream has shut down . This was QuadDream: Key Findings Based on an analysis of samples shared with us by Microsoft Threat Intelligence , we developed indicators that enabled us to identify at least five civil society victims of QuaDream’s spyware and exploits in North America, Central Asia, Southeast Asia, Europe, and the Middle East. Victims include journalists, political opposition figures, and an NGO worker. We are not naming the victims at this time. We also identify traces of a suspected iOS 14 zero-click exploit used to deploy QuaDream’s spyware. The exploit was deployed as a zero-day against iOS versions 14.4 and 14.4.2, and possibly other versions. The suspected exploit, which we call ENDOFDAYS , appears to make use of invisible iCloud calendar invitations sent from the spyware’s operator to victims.

TrustedSec - Better Hacking Through Cracking: Know Your Rules

Image
THIS POST WAS WRITTEN BY  @NYXGEEK Intro Password recovery tool hashcat ships with a bunch of great rules, but have you actually looked at them? Being familiar with the built-in rules can help enhance your cracking capabilities and enable you to choose the right rule or rule combination. via GIPHY So where are these rules anyways? The rules files exist in a “rules” folder that comes with hashcat. Here’s what a default rules folder will look like: One of the most basic things to know is how LONG the different rulesets are. How many permutations will be applied to the wordlist? This is important for gauging how long a job will take and decide which combinations of wordlist + rules might be completed in a timely manner. To find the length of the rulesets we could use “wc -l”, but there are some comments and blank lines in these rules. So for accuracy, use a little Bash one-liner: for file in `ls *.rule`; do echo -n "$file ";cat $file | grep -v '^#' | grep -v &
