A financially motivated threat actor known as UNC4990 is leveraging weaponized USB devices as an initial infection vector to target organizations in Italy.

Google-owned Mandiant said the attacks single out multiple industries, including health, transportation, construction, and logistics.

“UNC4990 operations generally involve widespread USB infection followed by the deployment of the EMPTYSPACE downloader,” the company said in a Tuesday report.

“During these operations, the cluster relies on third-party websites such as GitHub, Vimeo, and Ars Technica to host encoded additional stages, which it downloads and decodes via PowerShell early in the execution chain.”

UNC4990, active since late 2020, is assessed to be operating out of Italy based on the extensive use of Italian infrastructure for command-and-control (C2) purposes.

It’s currently not known if UNC4990 functions only as an initial access facilitator for other actors. The end goal of the threat actor is not clear, although in one instance an open-source cryptocurrency miner is said to have been deployed after months of beaconing activity.

Details of the campaign were previously documented by Fortgale and Yoroi in early December 2023, with the former tracking the adversary under the name Nebula Broker.

The infection begins when a victim double-clicks on a malicious LNK shortcut file on a removable USB device, leading to the execution of a PowerShell script that’s responsible for downloading EMPTYSPACE (aka BrokerLoader or Vetta Loader) from a remote server via another intermedia PowerShell script hosted on Vimeo.

Yoroi said it identified four different variants of EMPTYSPACE written in Golang, .NET, Node.js, and Python, which subsequently acts as a conduit for fetching next-stage payloads over HTTP from the C2 server, including a backdoor dubbed QUIETBOARD.

A notable aspect of this phase is the use of popular sites like Ars Technica, GitHub, GitLab, and Vimeo for hosting the malicious payload.

“The content hosted on these services posed no direct risk for the everyday users of these services, as the content hosted in isolation was completely benign,” Mandiant researchers said. “Anyone who may have inadvertently clicked or viewed this content in the past was not at risk of being compromised.”

QUIETBOARD, on the other hand, is a Python-based backdoor with a wide range of features that allow it to execute arbitrary commands, alter crypto wallet addresses copied to clipboard to redirect fund transfers to wallets under their control, propagate the malware to removable drives, take screenshots, and gather system information.

Additionally, the backdoor is capable of modular expansion and running independent Python modules like coin miners as well as dynamically fetching and executing Python code from the C2 server.

“The analysis of both EMPTYSPACE and QUIETBOARD suggests how the threat actors took a modular approach in developing their toolset,” Mandiant said.

“The use of multiple programming languages to create different versions of the EMPTYSPACE downloader and the URL change when the Vimeo video was taken down show a predisposition for experimentation and adaptability on the threat actors’ side.”

Italy’s data protection authority (DPA) has notified ChatGPT-maker OpenAI of supposedly violating privacy laws in the region.

“The available evidence pointed to the existence of breaches of the provisions contained in the E.U. GDPR [General Data Protection Regulation],” the Garante per la protezione dei dati personali (aka the Garante) said in a statement on Monday.

It also said it will “take account of the work in progress within the ad-hoc task force set up by the European Data Protection Framework (EDPB) in its final determination on the case.”

The development comes nearly 10 months after the watchdog imposed a temporary ban on ChatGPT in the country, weeks after which OpenAI announced a number of privacy controls, including an opt-out form to remove one’s personal data from being processed by the large language model (LLM). Access to the tool was subsequently reinstated in late April 2023.

The Italian DPA said the latest findings, which have not been publicly disclosed, are the result of a multi-month investigation that was initiated at the same time. OpenAI has been given 30 days to respond to the allegations.

BBC reported that the transgressions are related to collecting personal data and age protections. OpenAI, in its help page, says that “ChatGPT is not meant for children under 13, and we require that children ages 13 to 18 obtain parental consent before using ChatGPT.”

But there are also concerns that sensitive information could be exposed as well as younger users may be exposed to inappropriate content generated by the chatbot.

Indeed, Ars Technica reported this week that ChatGPT is leaking private conversations that include login credentials and other personal details of unrelated users who are said to be employees of a pharmacy prescription drug portal.

Then in September 2023, Google’s Bard chatbot was found to have a bug in the sharing feature that allowed private chats to be indexed by Google search, inadvertently exposing sensitive information that may have been shared in the conversations.

Generative artificial intelligence tools like ChatGPT, Bard, and Anthropic Claude rely on being fed large amounts of data from multiple sources on the internet.

In a statement shared with TechCrunch, OpenAI said its “practices align with GDPR and other privacy laws, and we take additional steps to protect people’s data and privacy.”

Apple Warns Against Proposed U.K. Law

The development comes as Apple said it’s “deeply concerned” about proposed amendments to the U.K. Investigatory Powers Act (IPA) could give the government unprecedented power to “secretly veto” privacy and security updates to its products and services.

“It’s an unprecedented overreach by the government and, if enacted, the U.K. could attempt to secretly veto new user protections globally preventing us from ever offering them to customers,” the tech giant told BBC.

The U.K. Home Office said adopting secure communications technologies, including end-to-end encryption, cannot come at the cost of public safety as well as protecting the nation from child sexual abusers and terrorists.

The changes are aimed at improving the intelligence services’ ability to “respond with greater agility and speed to existing and emerging threats to national security.”

Specifically, they require technology companies that field government data requests to notify the U.K. government of any technical changes that could affect their “existing lawful access capabilities.”

“A key driver for this amendment is to give operational partners time to understand the change and adapt their investigative techniques where necessary, which may in some circumstances be all that is required to maintain lawful access,” the government notes in a fact sheet, adding “it does not provide powers for the Secretary of State to approve or refuse technical changes.”

Apple, in July 2023, said it would rather stop offering iMessage and FaceTime services in the U.K. than compromise on users’ privacy and security.
