node-jose is a JavaScript implementation of the JSON Object Signing and Encryption (JOSE) for web browsers and node.js-based servers. Prior to version 2.2.0, when using the non-default "fallback" crypto back-end, ECC operations in `node-jose` can trigger a Denial-of-Service (DoS) condition, due to a possible infinite loop in an internal calculation. For some ECC operations, this condition is triggered randomly; for others, it can be triggered by malicious input. The issue has been patched in version 2.2.0. Since this issue is only present in the "fallback" crypto implementation, it can be avoided by ensuring that either WebCrypto or the Node `crypto` module is available in the JS environment where `node-jose` is being run.

Jon is back from parental leave and recapping the top security stories from late 2022 and early 2023 that totally blew by him.

### Description When using the non-default "fallback" crypto back-end, ECC operations in `node-jose` can trigger a Denial-of-Service (DoS) condition, due to a possible infinite loop in an internal calculation. For some ECC operations, this condition is triggered randomly; for others, it can be triggered by malicious input. #### Technical summary The JOSE logic implemented by `node-jose` usually relies on an external cryptographic library for the underlying cryptographic primitives that JOSE operations require. When WebCrypto or the Node `crypto` module are available, they are used. When neither of these libraries is available, `node-jose` includes its own "fallback" implementations of some algorithms based on `node-forge`, in particular implementations of ECDH and ECDSA. A various points, these algorithm implementations need to compute to the X coordinate of an elliptic curve point. This is done by calling the `getX()` method of the object representing the point, which is an a...

By Habiba Rashid Hackers are deploying the MortalKombat ransomware and Laplas Clipper malware in a financially motivated campaign against victims worldwide. This is a post from HackRead.com Read the original post: New MortalKombat Ransomware Attack Aiming for Crypto Wallets

SolarWinds Platform version 2022.4.1 was found to be susceptible to the Deserialization of Untrusted Data. This vulnerability allows a remote adversary with Orion admin-level account access to the SolarWinds Web Console to execute arbitrary commands.

A new financially motivated campaign that commenced in December 2022 has seen the unidentified threat actor behind it deploying a novel ransomware strain dubbed MortalKombat and a clipper malware known as Laplas. Cisco Talos said it "observed the actor scanning the internet for victim machines with an exposed remote desktop protocol (RDP) port 3389." The attacks, per the cybersecurity company,

Microsoft on Tuesday released security updates to address 75 flaws spanning its product portfolio, three of which have come under active exploitation in the wild. The updates are in addition to 22 flaws the Windows maker patched in its Chromium-based Edge browser over the past month. Of the 75 vulnerabilities, nine are rated Critical and 66 are rated Important in severity. 37 out of 75 bugs are
