Threat actors are conducting brute-drive attacks versus WordPress web sites by leveraging malicious JavaScript injections, new conclusions from Sucuri reveal.
The attacks, which choose the variety of dispersed brute-pressure attacks, “focus on WordPress internet sites from the browsers of completely innocent and unsuspecting web site people,” security researcher Denis Sinegubko stated.
The action is aspect of a previously documented attack wave in which compromised WordPress web pages ended up utilized to inject crypto drainers this sort of as Angel Drainer straight or redirect website visitors to Web3 phishing web sites made up of drainer malware.

The most up-to-date iteration is notable for the truth that the injections – found on about 700 web-sites to date – do not load a drainer but rather use a list of typical and leaked passwords to brute-drive other WordPress websites.
The attack unfolds around 5 stages, enabling a risk actor to consider benefit of now compromised internet websites to launch distributed brute-power attacks versus other likely sufferer websites –
- Obtaining a list of focus on WordPress web sites
- Extracting actual usernames of authors that write-up on those domains
- Inject the malicious JavaScript code to presently contaminated WordPress web pages
- Launching a dispersed brute-force attack on the goal websites through the browser when website visitors land on the hacked web-sites
- Gaining unauthorized entry to the target web pages
“For each individual password in the listing, the visitor’s browser sends the wp.uploadFile XML-RPC API request to add a file with encrypted qualifications that have been utilized to authenticate this unique ask for,” Sinegubko spelled out. “If authentication succeeds, a compact textual content file with valid qualifications is established in the WordPress uploads listing.”
It’s at the moment not recognized what prompted the danger actors to swap from crypto drainers to distributed brute-pressure attack, while it really is considered that the alter may perhaps have been pushed by income motives, as compromised WordPress internet sites could be monetized in many techniques.
That said, crypto wallet drainers have led to losses amounting to hundreds of thousands and thousands in electronic assets in 2023, according to details from Scam Sniffer. The Web3 anti-scam answer supplier has considering the fact that unveiled that drainers are exploiting the normalization procedure in the wallet’s EIP-712 encoding treatment to bypass security alerts.
The development arrives as the DFIR report disclosed that danger actors are exploiting a critical flaw in a WordPress plugin named 3DPrint Lite (CVE-2021-4436, CVSS rating: 9.8) to deploy the Godzilla web shell for persistent distant obtain.
It also follows a new SocGholish (aka FakeUpdates) campaign targeting WordPress websites in which the JavaScript malware is dispersed through modified variations of legitimate plugins that are mounted by taking advantage of compromised admin qualifications.
“While there have been a wide range of maliciously modified plugins and many distinct faux-browser update campaigns, the target of system is normally the similar: To trick unsuspecting website visitors into downloading remote access trojans that will later on be utilized as the initial stage of entry for a ransomware attack,” security researcher Ben Martin said.
