Each of these incidents involved the malware called Cloudflare [.]solutions.
Denis Sinegubko, a senior malware researcher at Sucuri, said: “While those new attacks no longer seem as large as the original Cloudflare[.]answers marketing campaign, the reinfection charge shows that there are still many websites that have failed to shield themselves after the original contamination correctly.”
New domain names
Following the December campaign, the Cloudflare solutions, the domains were taken down, but the cybercriminals at the back of the preliminary marketing campaign have finally registered new domains to host the malware. The domains are (cdjs[.]on line, cdns[.]ws and msdns[.]online).
