Threat actors have been observed serving malicious code by utilizing Binance's Smart Chain (BSC) contracts in what has been described as the "next level of bulletproof hosting."

The campaign, detected two months ago, has been codenamed **EtherHiding** by Guardio Labs.

The novel twist marks the latest iteration in an ongoing campaign that leverages compromised WordPress sites to serve unsuspecting visitors a fake warning to update their browsers before the sites can be accessed, ultimately leading to the deployment of information stealer malware such as Amadey, Lumma, or RedLine.

"While their initial method of hosting code on abused Cloudflare Worker hosts was taken down, they've quickly pivoted to take advantage of the decentralized, anonymous, and public nature of blockchain," security researchers Nati Tal and Oleg Zaytsev said.

"This campaign is up and harder than ever to detect and take down."

It's no surprise that threat actors have targeted WordPress sites via both malicious plugins, as well as take advantage of publicly disclosed security flaws in popular plugins to breach websites. This gives the ability to completely hijack infected websites at will.

In the latest set of attacks, the infected sites are injected with obfuscated Javascript designed to query the BNB Smart Chain by creating a smart contract with an attacker-controlled blockchain address.

The goal is to fetch a second-stage script that, in turn, retrieves a third-stage payload from a command-and-control (C2) server to serve the deceptive browser update notices.

Should a victim click the update button on the bogus overlay, they are redirected to download a malicious executable from Dropbox or other legitimate file hosting services.

While the address and the associated contract have been tagged as used in a phishing scheme, the consequence of hosting it on a decentralized service means that there is currently no way to intervene and disrupt the attack chain.

"As this is not an address used in any financial or other activity that victims can be lured to transfer funds or any other kind of Intellectual property to — visitors of compromised WordPress sites have no clue as to what is going on under the hood," the researchers explained.

"This contract, tagged as fake, malicious, or whatnot, is still online and delivers the malicious payload."

With plugins becoming a sizable attack surface for WordPress, it's recommended that users relying on the content management system (CMS) adhere to security best practices and keep their systems up-to-date with the latest patches, remove unwanted admin users, and enforce strong passwords.

CVE-2023-40791: LKML: Yikebaer Aizezi: WARNING in try_grab_page

** DISPUTED ** An issue was discovered in the Linux kernel through 6.5.7. kvm_arch_vcpu_ioctl_run in arch/x86/kvm/x86.c allows a WARN_ON_ONCE if userspace stuffs a nonsensical vCPU state.

Well that's annoying.  The WARN is a sanity check that KVM doesn't somehow put  
the guest into an uninitialized state while emulating the guest's APIC timer, but  
I completely overlooked the fact that userspace can simply stuff the should-be-  
impossible guest state. \*sigh\*

Sadly, I think the most reasonable thing to do is to simply drop the sanity check :-(

A vulnerability was found in kphrx pleroma. It has been classified as problematic. This affects the function Pleroma.Emoji.Pack of the file lib/pleroma/emoji/pack.ex. The manipulation of the argument name leads to path traversal. The complexity of an attack is rather high. The exploitability is told to be difficult. This product does not use versioning. This is why information about affected and unaffected releases are unavailable. The patch is named 2c795094535537a8607cc0d3b7f076a609636f40. It is recommended to apply a patch to fix this issue. The associated identifier of this vulnerability is VDB-242187.

CVE-2023-5588: Merge develop 2023-08-08 by kphrx · Pull Request #197 · kphrx/pleroma

urllib3 before 1.24.2 does not remove the authorization HTTP header when following a cross-origin redirect (i.e., a redirect that differs in host, port, or scheme). This can allow for credentials in the authorization header to be exposed to unintended hosts or transmitted in cleartext. NOTE: this issue exists because of an incomplete fix for CVE-2018-20060 (which was case-sensitive).
