Hackers Use MS Excel Macro to Launch Multi-Stage Malware Attack in Ukraine

Jun 04, 2024 Cyber Attack / Malware
A new sophisticated cyber attack has been observed targeting endpoints geolocated to Ukraine with an aim to deploy Cobalt Strike and seize control of the compromised hosts. The attack chain, per Fortinet FortiGuard Labs, involves a Microsoft Excel file that carries an embedded VBA macro to initiate the infection, "The attacker uses a multi-stage malware strategy to deliver the notorious 'Cobalt Strike' payload and establish communication with a command-and-control (C2) server," security researcher Cara Lin said in a Monday report. "This attack employs various evasion techniques to ensure successful payload delivery." Cobalt Strike , developed and maintained by Fortra, is a legitimate adversary simulation toolkit used for red teaming operations. However, over the years, cracked versions of the software have been extensively exploited by threat actors for malicious purposes. The starting point of the attack is the Excel document that, when launched, dis

Grandoreiro Banking Trojan Resurfaces, Targeting Over 1,500 Banks Worldwide

May 19, 2024 Banking Troja / Email Security
The threat actors behind the Windows-based  Grandoreiro  banking trojan have returned in a global campaign since March 2024 following a law enforcement takedown in January. The large-scale phishing attacks, likely facilitated by other cybercriminals via a malware-as-a-service (MaaS) model, target over 1,500 banks across the world, spanning more than 60 countries in Central and South America, Africa, Europe, and the Indo-Pacific, IBM X-Force said. While  Grandoreiro  is known primarily for its focus in Latin America, Spain, and Portugal, the expansion is likely a shift in strategy after attempts to  shut down its infrastructure  by Brazilian authorities. Going hand-in-hand with the broader targeting footprint are significant improvements to the malware itself, which indicates active development. "Analysis of the malware revealed major updates within the string decryption and domain generating algorithm (DGA), as well as the ability to use Microsoft Outlook clients on infected
CTEM in the Spotlight: How Gartner's New Categories Help to Manage Exposures

CTEM in the Spotlight: How Gartner's New Categories Help to Manage Exposures

Aug 27, 2024Threat Management / Enterprise Security
Want to know what's the latest and greatest in SecOps for 2024? Gartner's recently released Hype Cycle for Security Operations report takes important steps to organize and mature the domain of Continuous Threat Exposure Management, aka CTEM. Three categories within this domain are included in this year's report: Threat Exposure Management, Exposure Assessment Platforms (EAP), and Adversarial Exposure Validation (AEV). These category definitions are aimed at providing some structure to the evolving landscape of exposure management technologies. Pentera, listed as a sample vendor in the newly defined AEV category, is playing a pivotal role in increasing the adoption of CTEM, with a focus on security validation. Following is our take on the CTEM related product categories and what they mean for enterprise security leaders. The Industry is Maturing CTEM, coined by Gartner in 2022, presents a structural approach for continuously assessing, prioritizing, validating, and remediating expo
LummaC2 Malware Deploys New Trigonometry-Based Anti-Sandbox Technique

LummaC2 Malware Deploys New Trigonometry-Based Anti-Sandbox Technique

Nov 20, 2023 Malware / Cyber Attack
The stealer malware known as  LummaC2  (aka Lumma Stealer) now features a new anti-sandbox technique that leverages the mathematical principle of trigonometry to evade detection and exfiltrate valuable information from infected hosts. The method is designed to "delay detonation of the sample until human mouse activity is detected," Outpost24 security researcher Alberto Marín  said  in a technical report shared with The Hacker News. Written in the C programming language, LummaC2 has been sold in underground forums since December 2022. The malware has since  received   iterative updates  that make it harder to analyze via control flow flattening and even allow it to deliver additional payloads. The current version of LummaC2 (v4.0) also requires its customers to use a  crypter  as an added concealing mechanism, not to mention prevent it from being leaked in its raw form. Another noteworthy update is the reliance on trigonometry to detect human behavior on the infiltrated
