Researchers: Professional-Ocean Malware Targets Apache, Oracle WebLogic Servers
A recently updated cryptojacking malware variant called Pro-Ocean is targeting vulnerable Apache and Oracle WebLogic servers, according to Palo Alto Networks’ Unit 42.

The malware is tied to a hacking group known as Rocke, which has been energetic since a minimum of 2018. Researchers from Cisco Talos first noticed the group, which is understood for mining for monero digital forex (see: Obama-Themed Ransomware Also Mines for Monero).
The up to date model of Professional-Ocean exhibits how Rocke has steadily elevated its capability to develop malware. The brand new variant presents worming and rootkit capabilities that allow the malicious code to stay undetected and compromise different susceptible net servers, the Unit 42 report notes.
“Cryptojacking malware concentrating on the cloud is evolving as attackers perceive the potential of that surroundings to mine for crypto cash,” the Unit 42 researchers notice. “We beforehand noticed easier assaults by the Rocke Group, nevertheless it appears this group presents an ongoing, rising risk. This cloud-targeted malware is just not one thing peculiar, because it has worm and rootkit capabilities. We are able to assume that the rising pattern of refined assaults on the cloud will proceed.”
The hacking group targets Apache ActiveMQ servers with the vulnerability often known as CVE-2016-3088 and Oracle WebLogic servers with the vulnerability CVE-2017-10271, in accordance with the report. The researchers additionally discovered the malware takes benefit of unsecured Redis servers – an in-memory information construction venture used for creating databases.
The Unit 42 report would not disclose how the assaults towards these susceptible net servers are initiated. However the researchers discovered the hacking group is internet hosting the up to date model of Professional-Ocean in professional cloud companies, such Tencent Cloud or Alibaba Cloud.
The Professional-Ocean malware, which is written within the Go programming language, contains a number of modules that every carry out separate capabilities, the report notes.
As soon as the malware is planted in a compromised server, one in every of its modules makes an attempt to kill different processes, together with different cryptominers, after which begins mining for monero cryptocurrency.
Professional-Ocean’s new capabilities embody a worming capability that makes use of a Python script as a substitute of a guide course of, enabling the malware to focus on different susceptible net servers.
“This script retrieves the machine’s public IP by accessing a web based service that does so within the deal with ‘ident.me’ after which tries to contaminate all of the machines in the identical 16-bit subnet (e.g. 10.0.X.X),” the Unit 42 report states. “It does this by blindly executing public exploits one after the opposite within the hope of discovering unpatched software program it could exploit.”
Different hacking teams, corresponding to TeamTNT, have additionally developed malware with worming capabilities in an effort to focus on susceptible cloud assets as a part of their cryptomining campaigns (see: Cryptomining Botnet Steals AWS Credentials).
The Unit 42 researchers additionally discovered the Professional-Ocean malware makes use of a rootkit to assist disguise its actions. It makes use of a local Linux function known as “LD_PRELOAD. LD_PRELOAD,” which forces binaries to load particular libraries earlier than others. This enables the preloaded libraries to override any perform from any library, in accordance with the report.
“This manner, as soon as executed, binaries will load this library and use its capabilities as a substitute of the capabilities within the default libraries. This function is usually abused by different malware,” the researchers say.
As within the earlier model of Professional-Ocean, the newest model makes use of Libprocesshider – a library for hiding processes. However the builders added a number of code snippets from the web to achieve extra rootkit capabilities, the report notes.
