Large-Scale Campaign Exploits Kubernetes RBAC for Cryptocurrency Mining

In a recently uncovered attack campaign, Kubernetes (K8s) Role-Based Access Control (RBAC) vulnerabilities have been exploited to establish backdoors and deploy cryptocurrency miners. Cloud security firm Aqua reported that attackers utilized DaemonSets to commandeer resources within targeted K8s clusters. Dubbed “RBAC Buster,” the campaign has reportedly infiltrated 60 unprotected K8s clusters. The attack began with the exploitation of a misconfigured API server, followed by a search for competing miner malware, and the establishment of persistence through RBAC adjustments. Aqua noted that the attacker created a new ClusterRole with almost admin-level permissions and set up a ‘ServiceAccount’ named ‘kube-controller’ in the ‘kube-system’ namespace.

Paperbug Exploit: New Politically-Driven Surveillance Initiative in Tajikistan

On April 27, 2023, a relatively obscure Russian-speaking cyber-espionage group has been identified as the orchestrator of a new politically motivated surveillance initiative targeting senior government officials, telecom services, and public infrastructure in Tajikistan. The operation, named Paperbug by the Swiss cybersecurity firm PRODAFT, has been linked to a threat actor known as Nomadic Octopus (also referred to as DustSquad). According to PRODAFT’s comprehensive technical report shared with The Hacker News, “The types of compromised machines range from individual computers to operational technology devices. These targets render ‘Operation Paperbug’ intelligence-driven.” While the ultimate motives behind the attacks are still uncertain, the cybersecurity firm has suggested the possibility of involvement from domestic opposition groups or an intelligence-gathering effort conducted by Russia or China. Nomadic Octopus first gained attention in October 2018.

Malware / Cyber Threat

Recent attacks by the China-aligned threat actor known as the Tonto Team have targeted South Korean education, construction, diplomatic, and political institutions. The AhnLab Security Emergency Response Center (ASEC) reported that the group is utilizing a file associated with anti-malware products to carry out their malicious activities. Active since at least 2009, Tonto Team has a history of attacks across various sectors in Asia and Eastern Europe. Earlier this year, they were linked to an unsuccessful phishing attempt on the cybersecurity firm Group-IB. According to ASEC, the attack begins with a Microsoft Compiled HTML Help (.CHM) file that runs a binary to side-load a malicious DLL (slc.dll) and deploy the ReVBShell backdoor, an open-source VBScript tool also used by another Chinese threat actor, Tick.

Three distinct threat actors exploited countless elaborate fake profiles on Facebook and Instagram to conduct targeted attacks against individuals in South Asia. “These advanced persistent threats (APTs) relied heavily on social engineering tactics to deceive users into clicking malicious links, downloading malware, or sharing sensitive information online,” stated Guy Rosen, Meta’s chief information security officer. “This focus on social engineering reduced their need to invest heavily in malware development.” The counterfeit accounts utilized traditional tactics, pretending to be romantic interests, recruiters, journalists, or military personnel. Notably, two cyber espionage initiatives involved low-sophistication malware, likely attempting to evade app verification measures from Apple and Google. Meta’s findings revealed…
