Researchers Uncover 'LLMjacking' Scheme Targeting Cloud-Hosted AI Models

Researchers Uncover 'LLMjacking' Scheme Targeting Cloud-Hosted AI Models

May 10, 2024 Vulnerability / Cloud Security
Cybersecurity researchers have discovered a novel attack that employs stolen cloud credentials to target cloud-hosted large language model (LLM) services with the goal of selling access to other threat actors. The attack technique has been codenamed  LLMjacking  by the Sysdig Threat Research Team. "Once initial access was obtained, they exfiltrated cloud credentials and gained access to the cloud environment, where they attempted to access local LLM models hosted by cloud providers," security researcher Alessandro Brucato  said . "In this instance, a local Claude (v2/v3) LLM model from Anthropic was targeted." The intrusion pathway used to pull off the scheme entails breaching a system running a vulnerable version of the Laravel Framework (e.g.,  CVE-2021-3129 ), followed by getting hold of Amazon Web Services (AWS) credentials to access the LLM services. Among the tools used is an  open-source Python script  that checks and validates keys f...
New TunnelVision Attack Allows Hijacking of VPN Traffic via DHCP Manipulation

New TunnelVision Attack Allows Hijacking of VPN Traffic via DHCP Manipulation

May 09, 2024 Encryption / Data Privacy
Researchers have detailed a Virtual Private Network (VPN) bypass technique dubbed  TunnelVision  that allows threat actors to snoop on victim's network traffic by just being on the same local network. The "decloaking"  method  has been assigned the CVE identifier  CVE-2024-3661  (CVSS score: 7.6). It impacts all operating systems that implement a DHCP client and has support for DHCP option 121 routes. At its core, TunnelVision involves the routing of traffic without encryption through a VPN by means of an attacker-configured DHCP server using the  classless static route option 121  to set a route on the VPN user's  routing table . It also stems from the fact the DHCP protocol, by design, does not authenticate such option messages, thus exposing them to manipulation. DHCP is a client/server protocol that automatically provides an Internet Protocol (IP) host with its IP address and other related configuration information such as ...
Kremlin-Backed APT28 Targets Polish Institutions in Large-Scale Malware Campaign

Kremlin-Backed APT28 Targets Polish Institutions in Large-Scale Malware Campaign

May 09, 2024 Mobile Security / Cyber Attack
Polish government institutions have been targeted as part of a large-scale malware campaign orchestrated by a Russia-linked nation-state actor called  APT28 . "The campaign sent emails with content intended to arouse the recipient's interest and persuade him to click on the link," the computer emergency response team, CERT Polska,  said  in a Wednesday bulletin. Clicking on the link redirects the victim to the domain run.mocky[.]io, which, in turn, is used to redirect to another legitimate site named webhook[.]site, a  free service  that allows developers to inspect data that's being sent via a webhook, in an effort to evade detection. The next step involves the download of a ZIP archive file from webhook[.]site, which contains the Windows Calculator binary that masquerades as a JPG image file ("IMG-238279780.jpg.exe"), a hidden batch script file, and another hidden DLL file ("WindowsCodecs.dll"). Should a victim run the application, the mali...

The Hidden Risks of SaaS: Why Built-In Protections Aren't Enough for Modern Data Resilience

The Hidden Risks of SaaS: Why Built-In Protections Aren't Enough for Modern Data Resilience

Jun 26, 2025Data Protection / Compliance
SaaS Adoption is Skyrocketing, Resilience Hasn't Kept Pace SaaS platforms have revolutionized how businesses operate. They simplify collaboration, accelerate deployment, and reduce the overhead of managing infrastructure. But with their rise comes a subtle, dangerous assumption: that the convenience of SaaS extends to resilience. It doesn't. These platforms weren't built with full-scale data protection in mind . Most follow a shared responsibility model — wherein the provider ensures uptime and application security, but the data inside is your responsibility. In a world of hybrid architectures, global teams, and relentless cyber threats, that responsibility is harder than ever to manage. Modern organizations are being stretched across: Hybrid and multi-cloud environments with decentralized data sprawl Complex integration layers between IaaS, SaaS, and legacy systems Expanding regulatory pressure with steeper penalties for noncompliance Escalating ransomware threats and inside...

Mirai Botnet Exploits Ivanti Connect Secure Flaws for Malicious Payload Delivery

Mirai Botnet Exploits Ivanti Connect Secure Flaws for Malicious Payload Delivery

May 09, 2024 Network Security / Botnet
Two recently disclosed security flaws in Ivanti Connect Secure (ICS) devices are being exploited to deploy the infamous  Mirai botnet . That's according to  findings  from Juniper Threat Labs, which said the vulnerabilities  CVE-2023-46805 and CVE-2024-21887  have been leveraged to deliver the botnet payload. While CVE-2023-46805 is an authentication bypass flaw, CVE-2024-21887 is a command injection vulnerability, thereby allowing an attacker to chain the two into an exploit chain to execute arbitrary code and take over susceptible instances. In the attack chain observed by the network security company, CVE-2023-46805 is exploited to gain access to the "/api/v1/license/key-status/;" endpoint, which is vulnerable to command injection, and inject the payload. As  previously outlined  by Assetnote in their technical deep dive of the CVE-2024-21887, the exploit is triggered by means of a request to "/api/v1/totp/user-backup-code/" to deplo...

A SaaS Security Challenge: Getting Permissions All in One Place 

A SaaS Security Challenge: Getting Permissions All in One Place 

May 08, 2024 Attack Surface / SaaS Security
Permissions in SaaS platforms like Salesforce, Workday, and Microsoft 365 are remarkably precise. They spell out exactly which users have access to which data sets. The terminology differs between apps, but each user's base permission is determined by their role, while additional permissions may be granted based on tasks or projects they are involved with. Layered on top of that are custom permissions required by an individual user.  For example, look at a sales rep who is involved in a tiger team investigating churn while also training two new employees. The sales rep's role would grant her one set of permissions to access prospect data, while the tiger team project would grant access to existing customer data. Meanwhile, special permissions are set up, providing the sales rep with visibility into the accounts of the two new employees. While these permissions are precise, however, they are also very complex. Application admins don't have ...
