### Impact The OpenSearch sink and source plugins in Data Prepper are configured to trust all SSL certificates by default when no certificate path was provided, making connections vulnerable to man-in-the-middle attacks. Prior to this fix, the OpenSearch sink and source plugins would automatically use a trust all SSL strategy when connecting to OpenSearch clusters if no certificate path was explicitly configured. This behavior bypassed SSL certificate validation, potentially allowing attackers to intercept and modify data in transit through man-in-the-middle attacks. The vulnerability affects connections to OpenSearch when the `cert` parameter is not explicitly provided. ### Patches Data Prepper 2.12.2 ### Workarounds If you cannot immediately upgrade to the fixed version, you can implement the following workaround. #### OpenSearch sink Add the `cert` parameter to your OpenSearch sink configuration with the path to your cluster's CA certificate. The following example shows how...

# Microsoft Security Advisory CVE-2025-55248 | .NET Information Disclosure Vulnerability ## <a name="executive-summary"></a>Executive summary Microsoft is releasing this security advisory to provide information about a vulnerability in .NET 8.0 and .NET 9.0. This advisory also provides guidance on what developers can do to update their applications to remove this vulnerability. A MITM (man in the middle) attacker may prevent use of TLS between client and SMTP server, forcing client to send data over unencrypted connection. ## Announcement Announcement for this issue can be found at https://github.com/dotnet/announcements/issues/372 ## <a name="mitigation-factors"></a>Mitigation factors Microsoft has not identified any mitigating factors for this vulnerability. ## <a name="affected-software"></a>Affected software * Any .NET 8.0 application running on .NET 8.0.20 or earlier. * Any .NET 9.0 application running on .NET 9.0.9 or earlier. ## <a name="affected-packages"></a>Affected...

This issue affects Apache Spark versions before 3.4.4, 3.5.2 and 4.0.0. Apache Spark versions before 4.0.0, 3.5.2 and 3.4.4 use an insecure default network encryption cipher for RPC communication between nodes. When spark.network.crypto.enabled is set to true (it is set to false by default), but spark.network.crypto.cipher is not explicitly configured, Spark defaults to AES in CTR mode (AES/CTR/NoPadding), which provides encryption without authentication. This vulnerability allows a man-in-the-middle attacker to modify encrypted RPC traffic undetected by flipping bits in ciphertext, potentially compromising heartbeat messages or application data and affecting the integrity of Spark workflows. To mitigate this issue, users should either configure spark.network.crypto.cipher to AES/GCM/NoPadding to enable authenticated encryption or enable SSL encryption by setting spark.ssl.enabled to true, which provides stronger transport security.

Spanish Guardia Civil and Group-IB arrest 'GoogleXcoder,' the 25-year-old Brazilian mastermind of the GXC Team, for selling AI-powered phishing kits and malware used to steal millions from banks across the US, UK, Spain, and Brazil.

Before an attacker ever sends a payload, they’ve already done the work of understanding how your environment is built. They look at your login flows, your JavaScript files, your error messages, your API documentation, your GitHub repos. These are all clues that help them understand how your systems behave. AI is significantly accelerating reconnaissance and enabling attackers to map your

Cybersecurity researchers have shed light on a previously undocumented threat actor called TA585 that has been observed delivering an off-the-shelf malware called MonsterV2 via phishing campaigns. The Proofpoint Threat Research Team described the threat activity cluster as sophisticated, leveraging web injections and filtering checks as part of its attack chains. "TA585 is notable because it

With just $800 in basic equipment, researchers found a stunning variety of data—including thousands of T-Mobile users’ calls and texts and even US military communications—sent by satellites unencrypted.

When tlsInsecure=False appears in a connection string, certificate validation is disabled. This vulnerability affects MongoDB Rust Driver versions prior to v3.2.5.

Cybersecurity company Huntress on Friday warned of "widespread compromise" of SonicWall SSL VPN devices to access multiple customer environments. "Threat actors are authenticating into multiple accounts rapidly across compromised devices," it said. "The speed and scale of these attacks imply that the attackers appear to control valid credentials rather than brute-forcing." A significant chunk of
