CRYSTALRAY Hackers Exploiting Popular Pentesting Tools

CRYSTALRAY has significantly expanded its operations. In particular, they have gone ahead to target over 1,500 victims through activities such as mass scanning of systems and the use of multiple bugs vulnerabilities.

The group’s major objectives include, stealing credentials that can be sold afterward, mining for cryptocurrencies like Bitcoin and Ethereum among others, and maintaining their existence within the victim environments.

To achieve this purpose, CRYSTALRAY uses ASN (Autonomous System Number) for network intelligence gathering, Zmap for very fast port scanning, HTTPX for http probing, and NUCLEI for vulnerability scanning as well as honeypot detection.

Often using Platypus or Sliver clients, the perpetrator modifies them with malicious payloads targeting vulnerable systems.

Sliver and Platypus are used by CRYSTALRAY to achieve persistence and command-and-control while SSH-SNAKE is an open-source worm that spreads across a victim’s network once it identifies SSH keys or credentials on the compromised system..

They aggressively collect these actions to sell them off at black markets thereby mining command histories that contain tokens for usernames and passwords called credentials.

BianLian Ransomware

BianLian ransomware, which emerged in 2022, has rapidly become one of the most active ransomware groups which mostly exploited RDP, ProxyShell, and SonicWall VPN vulnerabilities to get initial access.

However, early 2023 saw a change in its tactics where it largely shifted from encryption and double extortion to data theft and extortion, targeting industries such as law firms and the health sector.

However, BianLian has proven its resilience in 2024 with increased activity via new servers as well as an expanded command and control (C2) infrastructure.

The group has also been working on improving the backdoor capabilities of this malware by introducing a Linux variant which proves that there are changes in their attack patterns and operational techniques.

1.1TB of Disney’s Internal Data Breached

Threat actors have claimed responsibility for a significant data breach involving 1.1TB of Disney’s internal Slack chats. While this incident was first reported on July 12 by a hacktivist known as “NullBulge.”

The breach allegedly contains contents from around 10,000 channels including not yet released projects, codes and confidential login data.

They have affirmed they are doing this to protect artists’ rights instead of causing harm in any way as these hackers are affiliated with Club Penguin fan club.

This has led to calls for more secure corporate communication platforms such as Slack due to the alarming scale of the breach initially estimated at 2.6GB. Besides this Disney is yet to issue an official statement concerning the matter.

Pinterest Data Leak

“Tchao1337,” a hacker has accessed 60 million rows of user data in a database which put Pinterest under threat of possible data leak.

Reportedly the leaked information containing email addresses, usernames, user IDs, and IP addresses among other details compressed into a 1.59 gigabyte file.

It poses various risks like potential phishing attacks as well as identity theft if not fixed on time and consequently needs to be taken care of immediately.

As recommended by security experts, users need to reset their passwords, activate two-factor authentication, and constantly monitor their accounts for any suspicious activities.

Pinterest hasn’t released any official statement regarding the incident yet, however, people are encouraged to stay tuned to the company for more updates.

Tools Used By NullBulge Actor

The purpose of this report is to examine the cyber operations carried out by NullBulge against Disney’s internal comms where they released Slack private information.

NullBulge, established between April and June 2024, exploits advanced malware techniques like Python-based payloads and supply chain attacks that predominantly affect communities in AI and gaming.

Such as Async RATs as well as LockBit ransomware which infect genuine software repositories plus send malicious codes via GitHub or social media platforms.

This group sells stolen data and API keys on underground forums showing its financial motives.

Recommendations for corporations would include securing API keys, examining third-party code, and checking commit histories to minimize risks related to this kind of cyber threat.

Killer Ultra Malware
