A hacktivist group known as Head Mare has been linked to cyber attacks that exclusively target organizations located in Russia and Belarus. "Head Mare uses more up-to-date methods for obtaining initial access," Kaspersky said in a Monday analysis of the group's tactics and tools. "For instance, the attackers took advantage of the relatively recent CVE-2023-38831 vulnerability in WinRAR, which allows the attacker to execute arbitrary code on the system via a specially prepared archive. This approach allows the group to deliver and disguise the malicious payload more effectively." Head Mare, active since 2023, is one of the hacktivist groups attacking Russian organizations in the context of the Russo-Ukrainian conflict that began a year before. It also maintains a presence on X , where it has leaked sensitive information and internal documentation from victims. Targets of the group's attacks include governments, transportation, energy, manufacturing, ...

Cybersecurity researchers have unpacked the inner workings of a new ransomware variant called Cicada3301 that shares similarities with the now-defunct BlackCat (aka ALPHV) operation. "It appears that Cicada3301 ransomware primarily targets small to medium-sized businesses (SMBs), likely through opportunistic attacks that exploit vulnerabilities as the initial access vector," cybersecurity company Morphisec said in a technical report shared with The Hacker News. Written in Rust and capable of targeting both Windows and Linux/ESXi hosts, Cicada3301 first emerged in June 2024, inviting potential affiliates to join their ransomware-as-a-service (RaaS) platform via an advertisement on the RAMP underground forum. A notable aspect of the ransomware is that the executable embeds the compromised user's credentials, which are then used to run PsExec , a legitimate tool that makes it possible to run programs remotely. Cicada3301's similarities with BlackCat also extend t...

Mobile users in Brazil are the target of a new malware campaign that delivers a new Android banking trojan named Rocinante. "This malware family is capable of performing keylogging using the Accessibility Service, and is also able to steal PII from its victims using phishing screens posing as different banks," Dutch security company ThreatFabric said . "Finally, it can use all this exfiltrated information to perform device takeover (DTO) of the device, by leveraging the accessibility service privileges to achieve full remote access on the infected device." Some of the prominent targets of the malware include financial institutions such as Itaú Shop, Santander, with the phony apps masquerading as Bradesco Prime and Correios Celular, among others - Livelo Pontos (com.resgatelivelo.cash) Correios Recarga (com.correiosrecarga.android) Bradesco Prime (com.resgatelivelo.cash) Módulo de Segurança (com.viberotion1414.app) Source code analysis of the malware has ...

In the digital realm, secrets (API keys, private keys, username and password combos, etc.) are the keys to the kingdom. But what if those keys were accidentally left out in the open in the very tools we use to collaborate every day? A Single Secret Can Wreak Havoc Imagine this: It's a typical Tuesday in June 2024. Your dev team is knee-deep in sprints, Jira tickets are flying, and Slack is buzzing with the usual mix of cat memes and code snippets. Little do you know, buried in this digital chatter is a ticking time bomb – a plaintext credential that gives unfettered access to your company's crown jewels. Fast forward a few weeks, and you're in the middle of a CISO's worst nightmare. Terabytes of customer data, including millions of bank account details, have been exfiltrated. Your company is splashed across headlines, and new incidents are surfacing daily. The culprit? A secret inadvertently shared in a Jira comment. This isn't a far-fetched scenario. It happen...

Eight vulnerabilities have been uncovered in Microsoft applications for macOS that an adversary could exploit to gain elevated privileges or access sensitive data by circumventing the operating system's permissions-based model, which revolves around the Transparency, Consent, and Control ( TCC ) framework. "If successful, the adversary could gain any privileges already granted to the affected Microsoft applications," Cisco Talos said . "For example, the attacker could send emails from the user account without the user noticing, record audio clips, take pictures, or record videos without any user interaction." The shortcomings span various applications such as Outlook, Teams, Word, Excel PowerPoint, and OneNote. The cybersecurity company said malicious libraries could be injected into these applications and gain their entitlements and user-granted permissions, which could then be weaponized for extracting sensitive information depending on the access granted ...
