Cyclops Ransomware Group Unveils Go-Based Info Stealer for Cybercriminals

Threat actors associated with the Cyclops ransomware have been identified promoting malware designed to steal sensitive information from compromised systems. According to a recent report by Uptycs, the group markets its offerings on forums, seeking a share of profits from those using its tools for malicious activities. Cyclops ransomware is particularly notable for its ability to target major desktop operating systems, including Windows, macOS, and Linux, while also terminating any processes that might hinder encryption. The macOS and Linux versions are developed in Golang, utilizing a sophisticated encryption method that combines both asymmetric and symmetric techniques. The Go-based info stealer targets Windows and Linux systems, gathering critical data such as operating system details, computer name, and other specifications.

Cyclops Ransomware Group Introduces Go-Based Info Stealer for Cybercriminals

June 6, 2023

In recent developments within the cybercrime ecosystem, the Cyclops ransomware group has begun marketing a new variant of information-stealing malware, specifically designed to harvest sensitive data from compromised systems. According to a report from Uptycs, this threat actor is using online forums to promote its ransomware-as-a-service model, which includes a profit-sharing arrangement with those who utilize its tools for malicious purposes.

The Cyclops ransomware itself is noteworthy for its ability to target multiple major operating systems, including Windows, macOS, and Linux. This cross-platform capability positions Cyclops as a significant threat across diverse corporate environments. In addition to its multifaceted targeting, the malware is designed to proactively terminate any processes that might impede its encryption operations, thereby ensuring a more effective attack.

The newly introduced Go-based information stealer aims to infect Windows and Linux systems specifically. It captures crucial details such as operating system specifications, system identifiers, and user-level information. The use of the Go programming language enhances its performance and cross-platform compatibility, making it appealing for cybercriminal deployments.

Within this context, it’s vital for business owners to understand the potential tactics that align with these types of cyber incursions. The MITRE ATT&CK framework can offer insights into the adversary techniques that may have been employed. For instance, initial access could be gained through phishing campaigns or exploitation of system vulnerabilities. Once inside, adversaries may leverage persistence techniques to maintain control over compromised systems.

Privilege escalation techniques may also be relevant, allowing attackers to gain higher-level access to the victim’s resources, thereby increasing the damage potential. The Cyclops ransomware’s capability to disable processes that could hinder its function further illustrates a methodical approach to attack, emphasizing the need for robust endpoint security measures.

Organizations must remain vigilant against such threats, implementing comprehensive security protocols and regular training for employees on identifying suspicious behavior. As cyber threats continue to evolve, awareness of the tactics and techniques utilized by adversaries is crucial for safeguarding sensitive information and maintaining business integrity.

With the rise of sophisticated malware like the Cyclops information stealer, understanding the threat landscape becomes imperative for any business looking to protect its data assets effectively. Cybersecurity is no longer just an IT concern; it is a critical component of business resilience and reputational standing in the digital age.

Recent geopolitical strains between China and Taiwan have led to a significant rise in cyber attacks targeting the island nation. According to a report from the Trellix Advanced Research Center, “The conflict stemming from China’s claim over Taiwan, combined with Taiwan’s push for independence, has resulted in a troubling escalation of cyber threats.” These attacks, aimed at various sectors, primarily focus on deploying malware and stealing sensitive data. The cybersecurity firm noted a staggering four-fold increase in malicious emails between April 7 and April 10, 2023, with sectors such as networking, manufacturing, and logistics being particularly affected. Following this surge, the region saw a 15x spike in PlugX detections between April 10 and April 12, 2023.

Beware the ZIP File: Phishers Exploit .ZIP Domains to Deceive Victims

Cyber Threat / Online Security

A new phishing technique dubbed “file archiver in the browser” is being used to imitate file archiver software, such as WinRAR, within web browsers when victims visit a .ZIP domain. Security researcher mr.d0x revealed that this phishing attack involves creating a realistic landing page using HTML and CSS to mimic genuine file archive software, hosted on a .ZIP domain to enhance its legitimacy.

In a typical attack, cybercriminals can redirect users to a credential theft page when they click on a file that appears to be included within the fake ZIP archive. Another alarming tactic involves listing a harmless non-executable file, only for the actual download to be an executable file instead, as noted by mr.d0x…

Dark Pink APT Group Utilizes TelePowerBot and KamiKakaBot in Complex Campaigns

On May 31, 2023, it was reported that the Advanced Persistent Threat (APT) group known as Dark Pink has launched five new attacks targeting various organizations in Belgium, Brunei, Indonesia, Thailand, and Vietnam between February 2022 and April 2023. The targets include educational institutions, government agencies, military organizations, and non-profit entities, highlighting the group’s ongoing focus on high-value assets. Also referred to as the Saaiwc Group, Dark Pink is believed to originate from the Asia-Pacific region, primarily directing its attacks towards East Asia, with some activity observed in Europe. The group employs a variety of custom malware tools, including TelePowerBot and KamiKakaBot, to facilitate the exfiltration of sensitive data from compromised systems. “The group uses a range of sophisticated custom tools and deploys multiple kill chains, often leveraging spear-phishing emails,” noted Andrey Polovinkin, a security researcher at Group-IB, in a technical report.

The U.S. Cybersecurity and Infrastructure Security Agency (CISA) and the Federal Bureau of Investigation (FBI) have released a joint advisory about the ongoing exploitation of a newly identified critical flaw in Progress Software’s MOVEit Transfer application, which is being used to deploy ransomware. “The Cl0p Ransomware Group, also known as TA505, reportedly began taking advantage of an undisclosed SQL injection vulnerability in the MOVEit Transfer managed file transfer (MFT) solution,” the agencies noted. “Internet-facing MOVEit Transfer web applications were compromised with a web shell called LEMURLOOT, which was then utilized to extract data from the underlying databases.” This notorious cybercrime group has also issued a deadline to several affected organizations, demanding contact by June 14, 2023, or they risk having their stolen information disclosed. Microsoft is monitoring this activity under the name Lace Tempest (also known as Storm).
