An ongoing cyber attack campaign originating from China is targeting the Southeast Asian gambling sector to deploy Cobalt Strike beacons on compromised systems. Cybersecurity firm SentinelOne said the tactics, techniques, and procedures point to the involvement of a threat actor tracked as  Bronze Starlight  (aka Emperor Dragonfly or Storm-0401), which has been linked to the use of short-lived ransomware families as a smokescreen to conceal its espionage motives. "The threat actors abuse Adobe Creative Cloud, Microsoft Edge, and McAfee VirusScan executables vulnerable to DLL hijacking to deploy Cobalt Strike beacons," security researchers Aleksandar Milenkoski and Tom Hegel said in an analysis published today. It also bears noting that the campaign exhibits overlaps with an intrusion set monitored by ESET under the name Operation ChattyGoblin. This activity, in turn, shares commonalities with a supply chain attack that came to light last year leveraging a trojanized installer

  Threat actors' use of Cloudflare R2 to host phishing pages has witnessed a 61-fold increase over the past six months. "The majority of the phishing campaigns target Microsoft login credentials, although there are some pages targeting Adobe, Dropbox, and other cloud apps," Netskope security researcher Jan Michael said. Cloudflare R2 , analogous to Amazon Web Service S3, Google Cloud Storage, and Azure Blob Storage, is a data storage service for the cloud. The development comes as the total number of cloud apps from which malware downloads originate has increased to 167, with Microsoft OneDrive, Squarespace, GitHub, SharePoint, and Weebly taking the top five spots. The phishing campaigns identified by Netskope not only abuse Cloudflare R2 to distribute static phishing pages, but also leverage the company's Turnstile offering, a CAPTCHA replacement, to place such pages behind anti-bot barriers to evade detection. In doing so, it prevents online scanners like urlscan.io
