AI and the 2024 US Elections

October 3, 2024 - 5:55pm

Bruce Schneier

For years now, AI has undermined the public’s ability to trust what it sees, hears, and reads. The Republican National Committee released a provocative ad offering an “AI-generated look into the country’s possible future if Joe Biden is re-elected,” showing apocalyptic, machine-made images of ruined cityscapes and chaos at the border. Fake robocalls purporting to be from Biden urged New Hampshire residents not to vote in the 2024 primary election. This summer, the Department of Justice cracked down on a Russian bot farm that was using AI to impersonate Americans on social media, and OpenAI disrupted an ...

Weird Zimbra Vulnerability

Bruce Schneier

Hackers can execute commands on a remote computer by sending malformed emails to a Zimbra mail server. It’s critical, but difficult to exploit.

In an email sent Wednesday afternoon, Proofpoint researcher Greg Lesnewich seemed to largely concur that the attacks weren’t likely to lead to mass infections that could install ransomware or espionage malware. The researcher provided the following details:

• While the exploitation attempts we have observed were indiscriminate in targeting, we haven’t seen a large volume of exploitation attempts
• Based on what we have researched and observed, exploitation of this vulnerability is very easy, but we do not have any information about how reliable the exploitation is ...

California AI Safety Bill Vetoed

Bruce Schneier

Governor Newsom has vetoed the state’s AI safety bill.

I have mixed feelings about the bill. There’s a lot to like about it, and I want governments to regulate in this space. But, for now, it’s all EU.

(Related, the Council of Europe treaty on AI is ready for signature. It’ll be legally binding when signed, and it’s a big deal.)

Hacking ChatGPT by Planting False Memories into Its Data

September 27, 2024 - 12:20pm

Bruce Schneier

This vulnerability hacks a feature that allows ChatGPT to have long-term memory, where it uses information from past conversations to inform future conversations with that same user. A researcher found that he could use that feature to plant “false memories” into that context window that could subvert the model.

A month later, the researcher submitted a new disclosure statement. This time, he included a PoC that caused the ChatGPT app for macOS to send a verbatim copy of all user input and ChatGPT output to a server of his choice. All a target needed to do was instruct the LLM to view a web link that hosted a malicious image. From then on, all input and output to and from ChatGPT was sent to the attacker’s website...

Researchers say these illicit chat bots, which use custom jailbreaks to bypass content filtering, often veer into darker role-playing scenarios, including child sexual exploitation and rape.

This Windows PowerShell Phish Has Scary Potential

Many GitHub users this week received a novel phishing email warning of critical security holes in their code. Those who clicked the link for details were asked to distinguish themselves from bots by pressing a combination of keyboard keys that causes Microsoft Windows to download password-stealing malware. While it's unlikely that many programmers fell for this scam, it's notable because less targeted versions of it are likely to be far more successful against the average Windows user.
