A grouping of comparable menace exercise dubbed “Blue Mockingbird” tried to distribute Monero-mining malware payloads throughout its enterprise targets.
Red Canary Intel found that the earliest examples of Blue Mockingbird traced again to December 2019. In two of the incidents investigated by the safety agency, the menace gained entry right into a focused group’s community by exploiting a deserialization vulnerability (CVE-2019-18935) affecting public-facing net functions that carried out Telerik UI for ASP.NET AJAX. This course of enabled the menace to add two dynamic-link libraries (DLLs) to a Home windows IIS net server’s net app.
The principle payload dropped by Blue Mockingbird was XMRig, a well known Monero-mining device that adversaries have generally integrated into their assault campaigns. Not content material with one sufferer, digital attackers generally abused the distant desktop protocol (RDP) to maneuver laterally all through the community so they may distribute payloads all through the enterprise. This elevated the general efficacy and profitability of a single assault occasion.
Different Current Monero-Mining Campaigns
Blue Mockingbird isn’t the only Monero-mining assault marketing campaign that’s focused enterprises lately. Again in early 2018, for example, Kaseya issued a collection of patches in response to a vulnerability that some malicious actors had abused to focus on susceptible organizations with Monero-mining software program.
In Could 2018, Imperva noticed digital attackers exploiting a distant code execution (RCE) vulnerability to unfold the ‘Kitty’ Monero miner. Greater than a 12 months later in October 2019, Palo Alto Networks’ Unit 42 noticed a cryptojacking worm spreading via containers within the Docker Engine to activate a Monero miner.
