SAMSUNG ENGINEERS FEED SENSITIVE DATA TO CHATGPT, SPARKING WORKPLACE AI WARNINGS

In three separate incidents, engineers at the Korean electronics giant
reportedly shared sensitive corporate data with the AI-powered chatbot.

Recent reports about engineers at Samsung Electronics inadvertently leaking
sensitive company information via ChatGPT in three separate incidents highlight
why policies governing employee use of AI services in the workplace are quickly
becoming a must for enterprise organizations.



The Economist Korea, one of the first to report on the data leaks, described the
first incident as involving an engineer who pasted buggy source code from a
semiconductor database into ChatGPT, with a prompt to the chatbot to fix the
errors. In the second instance, an employee wanting to optimize code for
identifying defects in certain Samsung equipment pasted that code into ChatGPT.
The third leak resulted when an employee asked ChatGPT to generate the minutes
of an internal meeting at Samsung.

The incidents played out exactly the same way that researchers have been warning
that they could, since OpenAI made ChatGPT publicly available in
November. Security analysts have noted how, in all instances where users share
data with ChatGPT, the information ends up as training data for the machine
learning/large language model (ML/LLM). They have noted how someone could later
retrieve the data using the right prompts. 

ChatGPT creator, OpenAI, itself has warned users on the risk: "We are not able
to delete specific prompts from your history. Please don't share any sensitive
information in your conversations," OpenAI's user guide notes.




SAMSUNG ENACTS EMERGENCY ANTI-CHATGPT MEASURES

The situation has apparently prompted a rethink of ChatGPT use at Samsung after
the third incident, just barely three weeks after the South Korean electronics
giant allowed employees access to the generative AI tool. The company had
initially banned the technology over security and privacy concerns before
relenting.



The Economist reported Samsung's emergency measures to limit ChatGPT use
internally as including restricting employees from asking questions of ChatGPT
that were larger than 1,024 bytes and considering disciplinary action against
employees who share corporate data with LLMs such as ChatGPT.

Samsung did not respond to a Dark Reading request seeking clarification on the
three incidents and the company's response to them. Security researchers,
however, have been warning that such leaks could become common as employees
begin leveraging ChatGPT for various use cases within the enterprise.

A study that Cyberhaven conducted earlier this year found many workers at client
companies pasting source code, client data, regulated information, and other
confidential data into ChatGPT. Examples included an executive who pasted his
company's 2023 strategy document into the chatbot so it could generate a
PowerPoint slide presentation, and a doctor who entered a patient's name and
medical diagnosis so ChatGPT could generate a letter to the patient's insurance
company.




AI: A RISK VS. BENEFIT GAMBLE FOR ENTERPRISES

"From an employee's perspective, ChatGPT-like tools offer the potential to be
exponentially more productive, making them hard to ignore," says Krishna
Vishnubhotla, vice president of product strategy at Zimperium. However, it's
important to consider the risks vs. rewards equation, which will vary depending
on specific roles and responsibilities, he notes. For instance, employees
working with intellectual property would require more guidance and precautions
on how to use tools like ChatGPT he says: "It is crucial for organizations to
understand how productivity will look and where it will come from before they
embrace this opportunity."

Michael Rinehart, vice president of artificial intelligence at Securiti, says
it's important to remember that advanced Generative AI tools such as ChatGPT
cannot distinguish between what they should and should not memorize during
training. So, organizations that want to harness them for different use cases
should consider using tools for classifying, masking, or tokenizing personal and
other sensitive data.

Or "a second approach is the use of differential privacy. Differential privacy
offers provable protection of individuals in structured data," Rinehart says.


DIFFERENTIAL PRIVACY

Rinehart describes differential privacy as a technique for protecting data in a
dataset. "It involves adding noise — or error — to real data," he says. The
synthetic data will have many of the important characteristics of real-world
data without exposing the individuals in the dataset. "If used properly, even if
the synthetic dataset were leaked, privacy would still be protected.
Enterprise-grade synthetic data generators with differential privacy are now
available," he says.

Rinehart perceives attempts by organizations to ban ChatGPT use in the workplace
as ill conceived and unlikely to work. "A consistent story in the field of
security is that it may be better to offer a secure path to using a tool than to
block it," he says. "If a tool offers incredibly high benefits, people may
attempt to circumvent blocks to take advantage of it."

Melissa Bischoping, director of endpoint security at Tanium, says the issue with
sharing data to ChatGPT lies in the fact that the creators can see the data and
use it to understand how the model continues to train and grow. Once a user
shares information with ChatGPT, that information becomes part of the next
model. 

"As organizations want to enable use of powerful tools like ChatGPT, they should
explore options that allow them to leverage a privately trained model so their
valuable data is only used by their model and not leveraged by iterations on
training for the next publicly available model."
