Threat actors have been observed targeting semiconductor companies in East Asia with lures masquerading as Taiwan Semiconductor Manufacturing Company (TSMC) that are designed to deliver Cobalt Strike beacons. The intrusion set, per  EclecticIQ , leverages a backdoor called HyperBro, which is then used as a conduit to deploy the commercial attack simulation software and post-exploitation toolkit. An alternate attack sequence is said to have utilized a previously undocumented malware downloader to deploy Cobalt Strike, indicating that the threat actors devised multiple approaches to infiltrate targets of interest. The Dutch cybersecurity firm attributed the campaign to a China-linked threat actor owing to the use of HyperBro, which has been almost exclusively put to use by a threat actor known as  Lucky Mouse  (aka APT27, Budworm, and Emissary Panda). Tactical overlaps have also been unearthed between the adversary behind the attacks and another cluster tracked by Rec...

A version of an open source ransomware toolkit called  Cryptonite  has been observed in the wild with wiper capabilities due to its "weak architecture and programming." Cryptonite , unlike other ransomware strains, is not available for sale on the cybercriminal underground, and was instead offered for free by an actor named CYBERDEVILZ until recently through a GitHub repository. The source code and its forks have since been taken down. Written in Python, the malware employs the  Fernet module  of the cryptography package to encrypt files with a ".cryptn8" extension. But a  new sample  analyzed by Fortinet FortiGuard Labs has been found to lock files with no option to decrypt them back, essentially acting as a destructive data wiper. But this change isn't a deliberate act on part of the threat actor, but rather stems from a lack of quality assurance that causes the program to crash when attempting to display the ransom note after completing the encrypt...

In today's rapidly evolving threat landscape, safeguarding your organization against cyberattacks is more critical than ever. Traditional penetration testing (pentesting), while effective, often falls short due to its high costs, resource requirements, and infrequent implementation. Automated internal and external network pentesting is a game-changing solution, empowering organizations to stay ahead of attackers with cost-effective, frequent, and thorough security assessments. Strengthen Your Defenses: The Role of Internal and External Pentests  Effective cybersecurity requires addressing threats from both inside and outside your organization. Automated solutions streamline this process, enabling IT teams to implement a holistic and proactive defense strategy. Internal Pentesting: Securing the Core Internal pentesting simulates an attacker operating within your network, exposing vulnerabilities such as insider threats, compromised credentials, or breaches through physical or ...

An unidentified threat actor has been linked to an actively in-development malware toolkit called the "Eternity Project" that lets professional and amateur cybercriminals buy stealers, clippers, worms, miners, ransomware, and a distributed denial-of-service (DDoS) bot. What makes this malware-as-a-service (MaaS) stand out is that besides using a Telegram channel to communicate updates about the latest features, it also employs a  Telegram Bot  that enables the purchasers to build the binary. "The [threat actors] provide an option in the Telegram channel to customize the binary features, which provides an effective way to build binaries without any dependencies," researchers from Cyble  said  in a report published last week. Each of the modules can be leased separately and provides paid access to a wide variety of functions - Eternity Stealer  ($260 for an annual subscription) - An information stealer to siphon passwords, cookies, credit cards, browser cr...
