SparklingGoblin APT Hackers Using New Linux Variant of SideWalk Backdoor

SparklingGoblin APT Hackers Using New Linux Variant of SideWalk Backdoor

Sep 14, 2022
A Linux variant of a backdoor known as SideWalk was used to target a Hong Kong university in February 2021, underscoring the cross-platform abilities of the implant.  Slovak cybersecurity firm ESET, which detected the malware in the university's network, attributed the backdoor to a nation-state actor dubbed  SparklingGoblin . The unnamed university is said to have been already targeted by the group in May 2020 during the  student protests . "The group continuously targeted this organization over a long period of time, successfully compromising multiple key servers, including a print server, an email server, and a server used to manage student schedules and course registrations," ESET  said  in a report shared with The Hacker News. SparklingGoblin is the name given to a Chinese advanced persistent threat (APT) group with connections to the  Winnti umbrella  (aka APT41, Barium, Earth Baku, or Wicked Panda). It's primarily known for its attacks targeting various en
New SideWalk Backdoor Targets U.S.-based Computer Retail Business

New SideWalk Backdoor Targets U.S.-based Computer Retail Business

Aug 25, 2021
A computer retail company based in the U.S. was the target of a previously undiscovered implant called SideWalk as part of a recent campaign undertaken by a Chinese advanced persistent threat group primarily known for singling out entities in East and Southeast Asia. Slovak cybersecurity firm ESET attributed the malware to an advanced persistent threat it tracks under the moniker SparklingGoblin, an adversary believed to be connected to the Winnti umbrella group, noting its similarities to another backdoor dubbed  Crosswalk  that was put to use by the same threat actor in 2019. "SideWalk is a modular backdoor that can dynamically load additional modules sent from its C&C [command-and-control] server, makes use of Google Docs as a  dead drop resolver , and  Cloudflare workers  as a C&C server," ESET researchers Thibaut Passilly and Mathieu Tartare  said  in a report published Tuesday. "It can also properly handle communication behind a proxy." Since fir
Timing is Everything: The Role of Just-in-Time Privileged Access in Security Evolution

Timing is Everything: The Role of Just-in-Time Privileged Access in Security Evolution

Apr 15, 2024Active Directory / Attack Surface
To minimize the risk of privilege misuse, a trend in the privileged access management (PAM) solution market involves implementing just-in-time (JIT) privileged access. This approach to  privileged identity management  aims to mitigate the risks associated with prolonged high-level access by granting privileges temporarily and only when necessary, rather than providing users with continuous high-level privileges. By adopting this strategy, organizations can enhance security, minimize the window of opportunity for potential attackers and ensure that users access privileged resources only when necessary.  What is JIT and why is it important?   JIT privileged access provisioning  involves granting privileged access to users on a temporary basis, aligning with the concept of least privilege. This principle provides users with only the minimum level of access required to perform their tasks, and only for the amount of time required to do so. One of the key advantages of JIT provisioning
