Cybersecurity researchers are warning that threat actors are actively exploiting a "disputed" and unpatched vulnerability in an open-source artificial intelligence (AI) platform called Anyscale Ray to hijack computing power for illicit cryptocurrency mining. "This vulnerability allows attackers to take over the companies' computing power and leak sensitive data," Oligo Security researchers Avi Lumelsky, Guy Kaplan, and Gal Elbaz  said  in a Tuesday disclosure. "This flaw has been under active exploitation for the last seven months, affecting sectors like education, cryptocurrency, biopharma, and more." The campaign, ongoing since September 2023, has been codenamed  ShadowRay  by the Israeli application security firm. It also marks the first time AI workloads have been targeted in the wild through shortcomings underpinning the AI infrastructure. Ray is an  open-source, fully-managed compute framework  that allows organizations to build, train, and

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

Designed to be more than a one-time assessment— Wing Security's SaaS Pulse provides organizations with actionable insights and continuous oversight into their SaaS security posture—and it's free! Introducing SaaS Pulse: Free Continuous SaaS Risk Management  Just like waiting for a medical issue to become critical before seeing a doctor, organizations can't afford to overlook the constantly evolving risks in their SaaS ecosystems. New SaaS apps, shifting permissions, and emerging threats mean risks are always in motion. SaaS Pulse makes it easy to treat SaaS risk management as an ongoing practice, not just an occasional check-up. Security teams instantly get a real-time security "health" score, prioritized risks, contextualized threat insights, and the organization's app inventory—without setups or integrations. SaaS is a Moving Target SaaS stacks don't stand still. Business critical apps can easily slip into a state of vulnerability (i.e. supply chain attacks, account takeovers

A recently disclosed server-side request forgery ( SSRF ) vulnerability impacting Ivanti Connect Secure and Policy Secure products has come under mass exploitation. The Shadowserver Foundation  said  it observed exploitation attempts originating from more than 170 unique IP addresses that aim to establish a reverse shell, among others. The attacks exploit  CVE-2024-21893  (CVSS score: 8.2), an SSRF flaw in the SAML component of Ivanti Connect Secure, Policy Secure, and Neurons for ZTA that allows an attacker to access otherwise restricted resources without authentication. Ivanti had previously divulged that the vulnerability had been exploited in targeted attacks aimed at a "limited number of customers," but cautioned the status quo could change post public disclosure. That's exactly what appears to have happened, especially following the  release  of a proof-of-concept (PoC) exploit by cybersecurity firm Rapid7 last week. The PoC involves fashioning an exploit cha

A previously undocumented threat actor has been linked to a cyber attack targeting an aerospace organization in the U.S. as part of what's suspected to be a cyber espionage mission. The BlackBerry Threat Research and Intelligence team is tracking the activity cluster as  AeroBlade . Its origin is currently unknown and it's not clear if the attack was successful. "The actor used spear-phishing as a delivery mechanism: A weaponized document, sent as an email attachment, contains an embedded remote template injection technique and a malicious VBA macro code, to deliver the next stage to the final payload execution," the company  said  in an analysis published last week. The network infrastructure used for the attack is said to have gone live around September 2022, with the offensive phase of the intrusion occurring nearly a year later in July 2023, but not before the adversary took steps to improvise its toolset to make it more stealthy in the intervening time perio

New research has unearthed multiple novel attacks that break Bluetooth Classic's forward secrecy and future secrecy guarantees, resulting in adversary-in-the-middle (AitM) scenarios between two already connected peers. The issues, collectively named  BLUFFS , impact Bluetooth Core Specification 4.2 through 5.4. They are tracked under the identifier  CVE-2023-24023  (CVSS score: 6.8) and were responsibly disclosed in October 2022. The attacks "enable device impersonation and machine-in-the-middle across sessions by only compromising one session key," EURECOM researcher Daniele Antonioli said in a study published late last month. This is made possible by leveraging two new flaws in the Bluetooth standard's session key derivation mechanism that allow the derivation of the same key across sessions. While forward secrecy in key-agreement cryptographic protocols ensures that past communications are not revealed, even if the private keys to a particular exchange are re
