A security vulnerability has been identified in Apache Kafka. It affects all releases since 2.8.0. The vulnerability allows malicious unauthenticated clients to allocate large amounts of memory on brokers. This can lead to brokers hitting OutOfMemoryException and causing denial of service. Example scenarios: - Kafka cluster without authentication: Any clients able to establish a network connection to a broker can trigger the issue. - Kafka cluster with SASL authentication: Any clients able to establish a network connection to a broker, without the need for valid SASL credentials, can trigger the issue. - Kafka cluster with TLS authentication: Only clients able to successfully authenticate via TLS can trigger the issue. We advise the users to upgrade the Kafka installations to one of the 3.2.3, 3.1.2, 3.0.2, 2.8.2 versions.

By Jon Munshaw.  Welcome to this week’s edition of the Threat Source newsletter.  Public schools in the United States already rely on our teachers for so much — they have to be educators, occasional parental figures, nurses, safety officers, law enforcement and much more. Slowly, they’re having to add “IT admin” to their list of roles.  Educational institutions have increasingly become a target for ransomware attacks, an issue already highlighted this year by a major cyber attack on the combined Los Angeles school district in California that schools are still recovering from.  Teachers there reported that during the week of the attack, they couldn’t enter attendance, lost lesson plans and presentations, and had to scrap homework plans. Technology has become ever-present in classrooms, so any minimal disruption in a school’s network or software can throw pretty much everything off.  The last thing teachers need to worry about now is defending against a well-funded threat act...

Insufficient access control vulnerability was discovered in the Crestron AirMedia Windows Application, version 4.3.1.39, in which a user can pause the uninstallation of an executable to gain a SYSTEM level command prompt.

An analysis of cloud services finds that known vulnerabilities typically open the door for attackers, while insecure cloud architectures allow them to gain access to the crown jewels.

A slew of Microsoft Exchange vulnerabilities (including ProxyLogon) fueled a surge in attacks targeting software flaws in 2021, but the trend has continued this year.

By Jung soo An, Asheer Malhotra and Vitor Ventura. Cisco Talos has been tracking a new campaign operated by the Lazarus APT group, attributed to North Korea by the United States government. This campaign involved the exploitation of vulnerabilities in VMWare Horizon to gain an initial foothold into targeted organizations. Targeted organizations include energy providers from around the world, including those headquartered in the United States, Canada and Japan. The campaign is meant to infiltrate organizations around the world for establishing long term access and subsequently exfiltrating data of interest to the adversary's nation-state. Talos has discovered the use of two known families of malware in these intrusions — VSingle and YamaBot. Talos has also discovered the use of a recently disclosed implant we're calling "MagicRAT" in this campaign. Introduction Cisco Talos observed North Korean state-sponsored APT Lazarus Group conducting malicious activity between February...

Microsoft's threat intelligence division on Wednesday assessed that a subgroup of the Iranian threat actor tracked as Phosphorus is conducting ransomware attacks as a "form of moonlighting" for personal gain. The tech giant, which is monitoring the activity cluster under the moniker DEV-0270 (aka Nemesis Kitten), said it's operated by a company that functions under the public aliases Secnerd and

GoCD is a continuous delivery server. Windows installations via either the server or agent installers for GoCD prior to 22.2.0 do not adequately restrict permissions when installing outside of the default location. This could allow a malicious user with local access to the server GoCD Server or Agent are installed on to modify executables or components of the installation. This does not affect zip file-based installs, installations to other platforms, or installations inside `Program Files` or `Program Files (x86)`. This issue is fixed in GoCD 22.2.0 installers. As a workaround, if the server or agent is installed outside of `Program Files (x86)`, verify the the permission of the Server or Agent installation directory to ensure the `Everyone` user group does not have `Full Control`, `Modify` or `Write` permissions.

Google on Monday introduced a new bug bounty program for its open source projects, offering payouts anywhere from $100 to $31,337 (a reference to eleet or leet) to secure the ecosystem from supply chain attacks. Called the Open Source Software Vulnerability Rewards Program (OSS VRP), the offering is one of the first open source-specific vulnerability programs. With the tech giant the maintainer
