An analysis of the newly emerged ransomware strain, RansomHub, reveals it to be an updated and rebranded version of Knight ransomware, which itself is an evolution of the earlier Cyclops ransomware.

Knight, also known as Cyclops 2.0, first appeared in May 2023. It utilizes double extortion tactics, stealing and encrypting victims’ data for financial gain. This ransomware is capable of operating across various platforms, including Windows, Linux, macOS, ESXi, and Android.

Marketed and sold on the RAMP cybercrime forum, Knight ransomware attacks have been found to employ phishing and spear-phishing campaigns as their primary distribution method, using malicious attachments.

The ransomware-as-a-service (RaaS) operation associated with Knight ceased operations in late February 2024. At that time, its source code was put up for sale, suggesting it might have been acquired by a different actor. This new actor likely updated and relaunched the ransomware under the RansomHub brand.

RansomHub, which announced its first victim in February 2024, has since been implicated in several recent ransomware attacks, including those on Change Healthcare, Christie’s, and Frontier Communications. The group behind RansomHub has declared that it will not target entities in Commonwealth of Independent States (CIS) countries, Cuba, North Korea, and China.

"Cuttlefish Malware Emerges: Router Hijacking and Cloud Credential Theft."

A new strain of malware, dubbed Cuttlefish, has surfaced with a primary focus on infiltrating small office and home office (SOHO) routers. This sophisticated malware aims to stealthily intercept all network traffic passing through the compromised routers, particularly targeting HTTP GET and POST requests to extract authentication data. Developed as a modular threat, Cuttlefish demonstrates advanced capabilities including DNS and HTTP hijacking within private IP spaces.

Though exhibiting similarities to the HiatusRAT, Cuttlefish operates independently, actively infecting routers since July 2023, with a recent surge observed from October 2023 to April 2024, predominantly affecting networks associated with Turkish telecom providers. While the precise method of initial access remains undisclosed, once inside a network, Cuttlefish executes a bash script to gather crucial host information and deploy its payload tailored to the router's architecture.

Notably, the malware employs an extended Berkeley Packet Filter (eBPF) to specifically target authentication data linked to major cloud service providers like Alicloud, AWS, Digital Ocean, CloudFlare, and BitBucket. By commandeering traffic destined for private IPs or activating a sniffer for public IPs under specific conditions, Cuttlefish efficiently pilfers credentials. Moreover, it can act as a proxy or VPN to transmit stolen data, enabling threat actors to access targeted cloud resources.

This multi-faceted approach underscores Cuttlefish's status as a cutting-edge threat in the realm of passive eavesdropping malware, posing significant risks to network security and cloud ecosystems alike.

"Former NSA Employee Sentenced to 22 Years for Attempting to Sell U.S. Secrets to Russia"

A former employee of the U.S. National Security Agency (NSA) has been sentenced to nearly 22 years in prison for his involvement in attempting to transfer classified documents to Russia. Jareh Sebastian Dalke, 32, of Colorado Springs, worked briefly as an Information Systems Security Designer at the NSA, during which time he accessed sensitive information. Dalke made contact with someone he believed to be a Russian agent, but who was an undercover FBI agent, and attempted to sell top-secret National Defense Information (NDI) for $85,000.

He emailed snippets of classified documents and later transferred files to the undercover agent before his arrest in 2022. Dalke pleaded guilty to the charges, admitting to willfully transmitting files with the intent to harm the United States and benefit Russia.

The case serves as a reminder of the consequences of betraying national security trust and highlights the efforts of law enforcement to prevent espionage activities.

"Malicious Google Ads Exploit Fake IP Scanner Software to Distribute Stealthy Backdoor."

A recent malvertising scheme uncovered by Zscaler ThreatLabz researchers reveals a sophisticated ploy exploiting Google Ads to disseminate a new Windows backdoor named MadMxShell. Threat actors utilized a network of deceptive domains resembling legitimate IP scanner software to lure unsuspecting users.

Upon visiting these sites, users unwittingly trigger the download of a malicious file disguised as a legitimate IP scanner tool. This file, upon ex*****on, deploys a multi-stage infection process, employing DLL side-loading and DNS tunneling for command-and-control communication. The backdoor, aptly named for its utilization of DNS MX queries for C2, allows the threat actor to gather system information, execute commands, and manipulate files on infected systems.

With no clear origin or motive identified for the malware operators, the discovery underscores the evolving tactics of cybercriminals and the critical need for robust security measures to thwart such malicious campaigns.
