Ransomware gangs continued to wreak havoc in 2024, but new research shows that the amounts victims paid these cybercriminals fell by hundreds of millions of dollars.

A global phishing campaign is actively exploiting a legacy Microsoft authentication system to steal user credentials and bypass multi-factor authentication (MFA), targeting over 150 organizations.

Organizations continue to be at high risk from cybercrime in Africa, despite law enforcement takedowns of cybercriminal syndicates in Nigeria and other African nations.

The security startup's autonomous security remediation platform uses off-the-shelf large language models (LLMs) to analyze security alerts and apply the fixes.

### Impact During recovery, a Coordinator only verifies that a given recovery key decrypts the sealed state, not if this key was provided by a party with access to one of the recovery keys defined in the manifest. This allows an attacker to manually craft a sealed state using their own recovery keys, and a manifest that does not match the rest of the state. If network traffic is redirected from the legitimate coordinator to the attacker's Coordinator, a remote party is susceptible to impersonation if they verify the Coordinator without comparing the root certificate of the Coordinator against a trusted reference. Under these circumstances, an attacker can trick a remote party into trusting the malicious Coordinator by presenting a manifest that does not match the actual state of the deployment. This issue does **not** affect the following: * secrets and state of the legitimate Coordinator instances * integrity of workloads * certificates chaining back to the legitimate Coordinator...

Funnull CDN rents IPs from legitimate cloud service providers and uses them to host criminal websites, continuously cycling cloud resources in and out of use and acquiring new ones to stay ahead of cyber-defender detection.

# CWA-2025-002 **Severity** Medium (Moderate + Likely)[^1] **Affected versions:** - wasmvm >= 2.2.0, < 2.2.2 - wasmvm >= 2.1.0, < 2.1.5 - wasmvm >= 2.0.0, < 2.0.6 - wasmvm < 1.5.8 **Patched versions:** - wasmvm 1.5.8, 2.0.6, 2.1.5, 2.2.2 ## Description of the bug The vulnerability can be used to slow down block production. The attack requires a malicious contract, so permissioned chains are unlikely to be affected. (We'll add more detail once chains had a chance to upgrade.) ## Patch - 1.5: https://github.com/CosmWasm/cosmwasm/commit/2b7f2faa57a1efc8207455c37f87f1eee6035a27 - 2.0: https://github.com/CosmWasm/cosmwasm/commit/d6143b0aff16a39bbea4be37597d8e9d9b213d3b - 2.1: https://github.com/CosmWasm/cosmwasm/commit/f0c04c03cbe2557634c1bbcdc2ce203fe7caca58 - 2.2: https://github.com/CosmWasm/cosmwasm/commit/a5d62f65b5eb947ebe40e2085b1c48a9d0a244d0 ## Applying the patch The patch will be shipped in releases of wasmvm. You can update more or less as follows: 1. Check the curre...

# CWA-2025-001 **Severity** Medium (Moderate + Likely)[^1] **Affected versions:** - wasmvm >= 2.2.0, < 2.2.2 - wasmvm >= 2.1.0, < 2.1.5 - wasmvm >= 2.0.0, < 2.0.6 - wasmvm < 1.5.8 **Patched versions:** - wasmvm 1.5.8, 2.0.6, 2.1.5, 2.2.2 ## Description of the bug The vulnerability can be used to crash the chain. The underlying bug that causes this is present on both permissioned and premissionless chains, but it can only be triggered _reliably_ with a malicious contract, so permissioned chains are much less likely to be affected. (We'll add more detail once chains had a chance to upgrade.) ## Patch - 1.5: https://github.com/CosmWasm/wasmvm/commit/1151bc6df7d02d1889b8da37cf8510eaf4198eea - 2.0: https://github.com/CosmWasm/wasmvm/commit/d4ff2adee44e6b9f7415a5dfbb3de745ab9b7678 - 2.1: https://github.com/CosmWasm/wasmvm/commit/8d44a286fabc793a2fba93752e58cd0fd5b88a2d - 2.2: https://github.com/CosmWasm/wasmvm/commit/0aefa4c378457aeb3c07e7975b875be38872c56d ## Applying the patch ...

### Summary Arbitrary remote Code Execution when accessing a malicious website while Vitest API server is listening by Cross-site WebSocket hijacking (CSWSH) attacks. ### Details When [`api` option](https://vitest.dev/config/#api) is enabled (Vitest UI enables it), Vitest starts a WebSocket server. This WebSocket server did not check Origin header and did not have any authorization mechanism and was vulnerable to CSWSH attacks. https://github.com/vitest-dev/vitest/blob/9a581e1c43e5c02b11e2a8026a55ce6a8cb35114/packages/vitest/src/api/setup.ts#L32-L46 This WebSocket server has `saveTestFile` API that can edit a test file and `rerun` API that can rerun the tests. An attacker can execute arbitrary code by injecting a code in a test file by the `saveTestFile` API and then running that file by calling the `rerun` API. https://github.com/vitest-dev/vitest/blob/9a581e1c43e5c02b11e2a8026a55ce6a8cb35114/packages/vitest/src/api/setup.ts#L66-L76 ### PoC 1.

### Summary `__screenshot-error` handler on the browser mode HTTP server that responds any file on the file system. Especially if the server is exposed on the network by [`browser.api.host: true`](https://vitest.dev/guide/browser/config.html#browser-api), an attacker can send a request to that handler from remote to get the content of arbitrary files. ### Details This `__screenshot-error` handler on the browser mode HTTP server responds any file on the file system. https://github.com/vitest-dev/vitest/blob/f17918a79969d27a415f70431e08a9445b051e45/packages/browser/src/node/plugin.ts#L88-L130 This code was added by https://github.com/vitest-dev/vitest/commit/2d62051f13b4b0939b2f7e94e88006d830dc4d1f. ### PoC 1. Create a directory and change the current directory to that directory 1. Run `npx vitest init browser` 1. Run `npm run test:browser` 2. Run `curl http://localhost:63315/__screenshot-error?file=/path/to/any/file` ### Impact Users explicitly exposing the browser mode server to th...
