The Unintended Consequences of Censoring Digital Technology - Evidence from Italy's ChatGPT Ban
by Fabio Alemagna Aug. 4, 2023

Aug. 4, 2023

Abstract "We analyse the effects of the ban of ChatGPT, a generative pre-trained transformer chatbot, on individual productivity. We first compile data on the hourly coding output of over 8,000 professional GitHub users in Italy and other European countries to analyse the impact of the ban on individual productivity. Combining the high-frequency data with the sudden announcement of the ban in a difference-in-differences framework, we find that the output of Italian developers decreased by around 50% in the first two business days after the ban and recovered after that. Applying a synthetic control approach to daily Google search and Tor usage data shows that the ban led to a significant increase in the use of censorship bypassing tools. Our findings show that users swiftly implement strategies to bypass Internet restrictions but this adaptation activity creates short-term disruptions and hampers productivity." https://dx.doi.org/10.2139/ssrn.4422548

Virtual Prompt Injection for Instruction-Tuned Large Language Models
by Alberto Cammozzo Aug. 2, 2023

Aug. 2, 2023

Virtual Prompt Injection for Instruction-Tuned Large Language Models <https://arxiv.org/abs/2307.16888> We present Virtual Prompt Injection (VPI) for instruction-tuned Large Language Models (LLMs). VPI allows an attacker-specified virtual prompt to steer the model behavior under specific trigger scenario without any explicit injection in model input. For instance, if an LLM is compromised with the virtual prompt "Describe Joe Biden negatively." for Joe Biden-related instructions, then any service deploying this model will propagate biased views when handling user queries related to Joe Biden. VPI is especially harmful for two primary reasons. Firstly, the attacker can take fine-grained control over LLM behaviors by defining various virtual prompts, exploiting LLMs' proficiency in following instructions. Secondly, this control is achieved without any interaction from the attacker while the model is in service, leading to persistent attack. To demonstrate the threat, we propose a simple method for performing VPI by poisoning the model's instruction tuning data. We find that our proposed method is highly effective in steering the LLM with VPI. For example, by injecting only 52 poisoned examples (0.1% of the training data size) into the instruction tuning data, the percentage of negative responses given by the trained model on Joe Biden-related queries change from 0% to 40%. We thus highlight the necessity of ensuring the integrity of the instruction-tuning data as little poisoned data can cause stealthy and persistent harm to the deployed model. We further explore the possible defenses and identify data filtering as an effective way to defend against the poisoning attacks. Our project page is available at <https://poison-llm.github.io/>

[Apologies if you receive multiple copies of this mail] ITC35 PhD Workshop, co-located with the 35th International Teletraffic Congress “Network Traffic Engineering in the TLC networks of the future” Wednesday, October 4, 2023, Turin Website: https://itc35.itc-conference.org/ CALL FOR PRESENTATIONS Re-thinking fundamental networking functions, their modeling and their performance evaluation in the framework of the evolving Internet and cellular networks, in the era of cloud and content providers, is a target for the ITC community. The PhD workshop aims at fostering contributions and fresh ideas from young researchers, pursuing their PhD or having just completed their PhD. Discussion of their PhD ideas and progress, proposition of research challenges and directions is welcome during a dedicated workshop. TRAVEL GRANTS The International Advisory Committee (IAC) of the ITC has decided to offer a number of travel grants (STG) that will be available to support full-time students for attending ITC 35th.

The Indonesian village that wants to cut off the internet | Indonesia | The Guardian
by Alberto Cammozzo July 29, 2023

July 29, 2023

<https://www.theguardian.com/world/2023/jul/28/the-village-that-wants-to-cut…> Four hours’ drive from the hustle and bustle of the Indonesian capital, Jakarta, lies the secluded community of Baduy Dalam, where the trapping of modern life are shunned. The Baduy Dalam people reject money, technology and formal education, and limits tourists – banning any visitors from documenting their life. Now the tribe wants to go one step further, by cutting off the internet. Officials in Indonesia are considering a request from the group for an internet blackout, after they cited concerns over negative impacts on tribe members. The Baduy community in Lebak, Banten province, is made up of two groups, Baduy Dalam and Baduy Luar, totalling about 26,000 people. Baduy Luar people have adopted contemporary ways of living, with some relying on the internet to attract tourists and promote their handcrafts. But a letter from representatives of Baduy Dalam, dated from June and shown to the Guardian by a local official, requests that the authorities remove or divert internet signals supplied by surrounding towers. Baduy Dalam representatives also asked that officials limit, reduce or close down applications that can affect the young generation’s morals. “The existence of phones/smartphones that can be owned by everyone, including Baduy people, is considered to result in the declining morals of our generation that can access non-educating applications and contents,” the letter reads. Lebak official Anik Sakinah said that her office had forwarded the request to Indonesia’s ministry of communications and information. Ministry official Usman Kansong said his office had coordinated with several internet providers operating towers around Baduy Dalam, which were currently conducting field surveys. He also noted concerns of tourists using the internet in the area. “It’s technically feasible, obviously with some treatments such as moving the towers or reducing the signal capacity. We’re still waiting for survey results on what can be done next,” Usman said. Baduy Dalam community location map Steve Saerang, representing one of the providers, Indosat Ooredoo Hutchison, said it supported the Baduy people’s cultural preservation but believed the internet had positive impacts on the economy. He added that the company had run a field survey but refused to comment further. Sarpin, a Baduy Luar village official and tour guide, said that while he agreed with Baduy Dalam’s request to preserve its tradition, it should not affect the adjacent Baduy Luar and other villages. As well as businesses and tourism, Sarpin said, essential government services relied on the internet. “We are requesting better internet signals. Some areas still don’t have access to the internet. It’s becoming more important for us,” he said by phone. While the world’s largest archipelago has enjoyed rising internet penetration, reaching almost 80% of its 275 million people, an urban-rural divide persists when it comes to access to the web. Endroyono, an information technology and communications expert from Sepuluh Nopember Institute of Technology, said that technically, operators could easily limit access in certain areas. But he suggested that the government also provide education on the positive use of the internet along Baduy Dalam borders to help younger generations cope with the changing world. “Digital divide should be addressed by the government through socio-cultural approaches. Whether we realise it or not, every citizen should benefit from technological advancement and should be protected from its negative excesses,” he said. Dubbed the Amish of Asia, Baduy people inhabit a 5,000ha area, over half of which is protected forest. There are more than 2,000 Indigenous groups with dozens of millions of members in Indonesia, according to the Indigenous Peoples Alliance of the Archipelago, and while they have a big role in nature conservation, they are subject to discrimination and human rights violations, especially in land conflicts. A bill on the recognition and protection of Indigenous people’s rights has stalled since 2012, depriving them of legal certainty, which activists say is fuelled by conflicted business interests.
