AI-as-a-Service Providers Vulnerable to PrivEsc and Cross-Tenant Attacks

AI-as-a-Service Providers Vulnerable to PrivEsc and Cross-Tenant Attacks

Apr 05, 2024 Artificial Intelligence / Supply Chain Attack
New research has found that artificial intelligence (AI)-as-a-service providers such as Hugging Face are susceptible to two critical risks that could allow threat actors to escalate privileges, gain cross-tenant access to other customers' models, and even take over the continuous integration and continuous deployment (CI/CD) pipelines. "Malicious models represent a major risk to AI systems, especially for AI-as-a-service providers because potential attackers may leverage these models to perform cross-tenant attacks," Wiz researchers Shir Tamari and Sagi Tzadik  said . "The potential impact is devastating, as attackers may be able to access the millions of private AI models and apps stored within AI-as-a-service providers." The development comes as machine learning pipelines have emerged as a brand new supply chain attack vector, with repositories like Hugging Face becoming an attractive target for staging adversarial attacks designed to glean sensitive infor
Over 100 Malicious AI/ML Models Found on Hugging Face Platform

Over 100 Malicious AI/ML Models Found on Hugging Face Platform

Mar 04, 2024 AI Security / Vulnerability
As many as 100 malicious artificial intelligence (AI)/machine learning (ML) models have been discovered in the Hugging Face platform. These include instances where loading a  pickle file  leads to code execution, software supply chain security firm JFrog said. "The model's payload grants the attacker a shell on the compromised machine, enabling them to gain full control over victims' machines through what is commonly referred to as a 'backdoor,'" senior security researcher David Cohen  said . "This silent infiltration could potentially grant access to critical internal systems and pave the way for large-scale data breaches or even corporate espionage, impacting not just individual users but potentially entire organizations across the globe, all while leaving victims utterly unaware of their compromised state." Specifically, the rogue model initiates a reverse shell connection to 210.117.212[.]93, an IP address that belongs to the Korea Research
The Drop in Ransomware Attacks in 2024 and What it Means

The Drop in Ransomware Attacks in 2024 and What it Means

Apr 08, 2024Ransomware / Cybercrime
The  ransomware industry surged in 2023  as it saw an alarming 55.5% increase in victims worldwide, reaching a staggering 5,070.  But 2024 is starting off showing a very different picture.  While the numbers skyrocketed in Q4 2023 with 1309 cases, in Q1 2024, the ransomware industry was down to 1,048 cases. This is a 22% decrease in ransomware attacks compared to Q4 2023. Figure 1: Victims per quarter There could be several reasons for this significant drop.  Reason 1: The Law Enforcement Intervention Firstly, law enforcement has upped the ante in 2024 with actions against both LockBit and ALPHV. The LockBit Arrests In February, an international operation named "Operation Cronos" culminated in the arrest of at least three associates of the infamous LockBit ransomware syndicate in Poland and Ukraine.  Law enforcement from multiple countries collaborated to take down LockBit's infrastructure. This included seizing their dark web domains and gaining access to their backend sys
