๐Ÿšจ New Malware Targets Docker APIs for Cryptomining! ๐Ÿš€๐Ÿ’ป

Exposed Docker APIs Under Attack! ๐Ÿณ๐Ÿ”“ Cybersecurity researchers have discovered a new malware campaign targeting publicly exposed Docker API endpoints to deliver cryptocurrency miners and other malicious payloads.

Campaign Tactics and Tools ๐Ÿ› ๏ธ๐Ÿ•ต๏ธ

  • Tools Deployed: Remote access tools capable of downloading more malware, and utilities for malware propagation via SSH.

  • Overlap: Shares tactics with the previous Spinning YARN campaign, which targeted Apache Hadoop YARN, Docker, Atlassian Confluence, and Redis services for cryptojacking.

Attack Sequence ๐ŸŽฏ๐Ÿ”

  1. Target: Docker servers with exposed ports (port 2375).

  2. Steps: Begins with reconnaissance and privilege escalation, followed by exploitation.

  3. Payload Retrieval: Uses a shell script named "vurl" to fetch additional payloads.

Malicious Payloads ๐Ÿฆ ๐Ÿ“ฆ

  • vurl: A binary that overwrites its shell script version, using hard-coded C2 domains.

  • Installs tools to scan for vulnerable hosts, disables firewalls, and fetches the next payload, "chkstart."

  • chkstart: Configures the host for remote access and fetches additional tools like "m.tar" (XMRig miner) and "top."

  • Exeremo: Moves laterally to spread the infection and drops the "" script for installing scanning tools.

  • fkoths: A Go-based binary to erase traces and resist analysis.

Evolving Threats ๐Ÿ›ก๏ธ๐Ÿ”„

The campaign indicates continuous attacks on misconfigured Docker hosts for initial access. By porting functionalities from shell scripts to Go, attackers complicate the analysis process, pointing to experimentation with multi-architecture builds.

Stay Alert! ๐Ÿ”’

Ensure your Docker configurations are secure to prevent falling victim to such sophisticated attacks!

Malaysian hackers: Singapore me ๐Ÿ˜ญ๐Ÿ˜ญ๐Ÿ˜ญ

๐Ÿšจ๐Ÿ•ต๏ธโ€โ™‚๏ธ Singapore's Malware Crackdown! ๐Ÿš”๐Ÿ‘จโ€โš–๏ธ

Major Extradition! ๐Ÿšจ๐ŸŒ The Singapore Police Force (SPF) has extradited two men from Malaysia for their role in a mobile malware scam since June 2023.

Malware Scams Unveiled ๐Ÿ•ต๏ธโ€โ™€๏ธ๐Ÿ“ฒ

The suspects, aged 26 and 47, used phishing campaigns to trick users into downloading malicious Android apps. These apps stole personal data and banking details, leading to financial losses.

Seven-Month Investigation ๐Ÿ”๐Ÿ‘ฎโ€โ™‚๏ธ

SPF, in collaboration with the Hong Kong Police Force and Royal Malaysia Police, linked the men to a syndicate behind these scams. The duo operated servers to infect phones and control them, enabling bank account compromises.

How the Scam Worked ๐Ÿ“ฑ๐Ÿ’€

Malicious apps posed as discount offers and, once installed, granted scammers remote access. They used the app to monitor SMS, track devices, and capture sensitive data.

Arrests and Consequences ๐Ÿš“โš–๏ธ

One suspect faces up to 7 years in prison and a $50,000 fine, while the other faces up to 10 years and a $500,000 fine. Taiwan Police also arrested four others involved in similar scams.

Operation DISTANTHILL Success ๐ŸŒ๐Ÿ‘

A total of 16 cyber criminals were arrested, and assets worth $1.33 million seized. Over 4,000 victims were defrauded.

US Dark Web Bust ๐Ÿ’ป๐Ÿ•ณ๏ธ

Separately, the U.S. Justice Department charged two men for operating Empire Market, a dark web marketplace trading $430 million in illegal goods. The operation ran from 2018 to 2020, leading to significant seizures and arrests.

๐Ÿšจ๐Ÿ”ง Critical ASUS Router Security Update! ๐Ÿ”ง๐Ÿ›ก๏ธ

Major Vulnerability Alert! โš ๏ธ๐Ÿ” ASUS has released software updates to fix a critical security flaw (CVE-2024-3080) in its routers, which could allow hackers to bypass authentication. This flaw has a CVSS score of 9.8/10.

Whatโ€™s the Issue? ๐Ÿค”๐Ÿ“ถ

  • Flaw: Authentication bypass

  • Impact: Remote attackers can log in without credentials

  • Reported by: Taiwan Computer Emergency Response Team (TWCERT/CC)

Additional Security Fixes ๐Ÿ› ๏ธ๐Ÿ›ก๏ธ

ASUS also patched a high-severity buffer overflow flaw (CVE-2024-3079, CVSS score: 7.2). This flaw could let attackers with admin privileges execute arbitrary commands.

Potential Exploit Chain ๐Ÿšจ๐Ÿ”—

Attackers could combine CVE-2024-3080 and CVE-2024-3079 to bypass authentication and run malicious code.

Affected Models ๐Ÿ“๐Ÿ“ถ

  • ZenWiFi XT8 (Fixed in

  • ZenWiFi XT8 V2 (Fixed in

  • RT-AX88U (Fixed in

  • RT-AX58U (Fixed in

  • RT-AX57 (Fixed in

  • RT-AC86U (Fixed in

  • RT-AC68U (Fixed in

Previous Patch ๐Ÿšจ๐Ÿ”ง

Earlier this year, ASUS fixed another critical flaw (CVE-2024-3912, CVSS score: 9.8) that allowed remote file uploads and command execution.

User Action Required ๐Ÿšจ๐Ÿ”„
