Researchers Warn of Chinese-Aligned Hackers Targeting South China Sea Countries

Researchers Warn of Chinese-Aligned Hackers Targeting South China Sea Countries

May 22, 2024 Cyber Espionage / Malware
Cybersecurity researchers have disclosed details of a previously undocumented threat group called  Unfading Sea Haze  that's believed to have been active since 2018. The intrusion singled out high-level organizations in South China Sea countries, particularly military and government targets, Bitdefender said in a report shared with The Hacker News. "The investigation revealed a troubling trend beyond the historical context," Martin Zugec, technical solutions director at Bitdefender,  said , adding it identified a total of eight victims to date. "Notably, the attackers repeatedly regained access to compromised systems. This exploitation highlights a critical vulnerability: poor credential hygiene and inadequate patching practices on exposed devices and web services." There are some indications that the threat actor behind the attacks is operating with goals that are aligned with Chinese interests despite the fact that the attack signatures do not overlap wit

Rockwell Advises Disconnecting Internet-Facing ICS Devices Amid Cyber Threats

May 22, 2024 ICS Security / Vulnerability
Rockwell Automation is urging its customers to disconnect all industrial control systems (ICSs) not meant to be connected to the public-facing internet to mitigate unauthorized or malicious cyber activity. The company  said  it's issuing the advisory due to "heightened geopolitical tensions and adversarial cyber activity globally." To that end, customers are required to take immediate action to determine whether they have devices that are accessible over the internet and, if so, cut off connectivity for those that are not meant to be left exposed. "Users should never configure their assets to be directly connected to the public-facing internet," Rockwell Automation further added. "Removing that connectivity as a proactive step reduces attack surface and can immediately reduce exposure to unauthorized and malicious cyber activity from external threat actors." On top of that, organizations are required to ensure that they have adopted the necessar

The Ultimate SaaS Security Posture Management Checklist, 2025 Edition

May 22, 2024 SaaS Security / Threat Detection
Since the first edition of  The Ultimate SaaS Security Posture Management (SSPM) Checklist  was released three years ago, the corporate SaaS sprawl has been growing at a double-digit pace. In large enterprises, the number of SaaS applications in use today is in the hundreds, spread across departmental stacks, complicating the job of security teams to protect organizations against evolving threats. As SaaS security becomes a top priority, enterprises are turning to SaaS Security Posture Management (SSPM) as an enabler. The  2025 Ultimate SaaS Security Checklist , designed to help organizations choose an SSPM, covers all the features and capabilities that should be included in these solutions. Before diving into each attack surface, when implementing an SSPM solution, it's essential to cover a breadth of integrations, including out-of-the-box and custom app integrations, as well as in-depth security checks. While there are apps that are more sensitive and complex to secure, a breach c

GHOSTENGINE Exploits Vulnerable Drivers to Disable EDRs in Cryptojacking Attack

GHOSTENGINE Exploits Vulnerable Drivers to Disable EDRs in Cryptojacking Attack

May 22, 2024 Cryptojacking / Malware
Cybersecurity researchers have discovered a new cryptojacking campaign that employs vulnerable drivers to disable known security solutions (EDRs) and thwart detection in what's called a Bring Your Own Vulnerable Driver ( BYOVD ) attack. Elastic Security Labs is tracking the campaign under the name REF4578 and the primary payload as GHOSTENGINE. Previous research from Chinese cybersecurity firm Antiy Labs has  codenamed  the activity as HIDDEN SHOVEL. "GHOSTENGINE leverages vulnerable drivers to terminate and delete known EDR agents that would likely interfere with the deployed and well-known coin miner," Elastic researchers Salim Bitam, Samir Bousseaden, Terrance DeJesus, and Andrew Pease  said . "This campaign involved an uncommon amount of complexity to ensure both the installation and persistence of the XMRig miner." It all starts with an executable file ("Tiworker.exe"), which is used to run a PowerShell script that retrieves an obfuscated Pow

MS Exchange Server Flaws Exploited to Deploy Keylogger in Targeted Attacks

May 22, 2024 Vulnerability / Data Breach
An unknown threat actor is exploiting known security flaws in Microsoft Exchange Server to deploy a keylogger malware in attacks targeting entities in Africa and the Middle East. Russian cybersecurity firm Positive Technologies said it identified over 30 victims spanning government agencies, banks, IT companies, and educational institutions. The first-ever compromise dates back to 2021. "This keylogger was collecting account credentials into a file accessible via a special path from the internet," the company  said  in a report published last week. Countries targeted by the intrusion set include Russia, the U.A.E., Kuwait, Oman, Niger, Nigeria, Ethiopia, Mauritius, Jordan, and Lebanon. The attack chains commence with the exploitation of  ProxyShell flaws  (CVE-2021-34473, CVE-2021-34523, and CVE-2021-31207) that were originally patched by Microsoft in May 2021. Successful  exploitation of the vulnerabilities  could allow an attacker to bypass authentication, elevate th

Zoom Adopts NIST-Approved Post-Quantum End-to-End Encryption for Meetings

Zoom Adopts NIST-Approved Post-Quantum End-to-End Encryption for Meetings

May 22, 2024 Encryption / Quantum Computing
Popular enterprise services provider Zoom has announced the rollout of post-quantum end-to-end encryption (E2EE) for Zoom Meetings, with support for Zoom Phone and Zoom Rooms coming in the future. "As adversarial threats become more sophisticated, so does the need to safeguard user data," the company  said  in a statement. "With the launch of post-quantum E2EE, we are doubling down on security and providing leading-edge features for users to help protect their data." Zoom's post-quantum E2EE uses  Kyber-768 , which aims at security roughly equivalent to AES-192. Kyber was  chosen  by the U.S. Department of Commerce's National Institute of Standards and Technology (NIST) in July 2022 as the quantum-resistant cryptographic algorithm for general encryption. However, for post-quantum E2EE to be enabled by default, it  requires  all meeting participants to be on Zoom desktop or mobile app version 6.0.10 or higher. In the event some of the participants don

What's the Right EDR for You?

May 10, 2024Endpoint Security / Threat Detection
A guide to finding the right endpoint detection and response (EDR) solution for your business' unique needs. Cybersecurity has become an ongoing battle between hackers and small- and mid-sized businesses. Though perimeter security measures like antivirus and firewalls have traditionally served as the frontlines of defense, the battleground has shifted to endpoints. This is why endpoint detection and response (EDR) solutions now serve as critical weapons in the fight, empowering you and your organization to detect known and unknown threats, respond to them quickly, and extend the cybersecurity fight across all phases of an attack.  With the growing need to defend your devices from today's cyber threats, however, choosing the right EDR solution can be a daunting task. There are so many options and features to choose from, and not all EDR solutions are made with everyday businesses and IT teams in mind. So how do you pick the best solution for your needs?

Malware Delivery via Cloud Services Exploits Unicode Trick to Deceive Users

May 21, 2024 Cloud Security / Data Security
A new attack campaign dubbed  CLOUD#REVERSER  has been observed leveraging legitimate cloud storage services like Google Drive and Dropbox to stage malicious payloads. "The VBScript and PowerShell scripts in the CLOUD#REVERSER inherently involves command-and-control-like activities by using Google Drive and Dropbox as staging platforms to manage file uploads and downloads," Securonix researchers Den Iuzvyk, Tim Peck, and Oleg Kolesnikov  said  in a report shared with The Hacker News. "The scripts are designed to fetch files that match specific patterns, suggesting they are waiting for commands or scripts placed in Google Drive or Dropbox." The starting point of the attack chain is a phishing email bearing a ZIP archive file, which contains an executable that masquerades as a Microsoft Excel file. In an interesting twist, the filename makes use of the hidden right-to-left override ( RLO ) Unicode character (U+202E) to reverse the order of the characters that co
