As many as 196 hosts have been infected as part of an aggressive cloud campaign mounted by the TeamTNT group called  Silentbob . "The botnet run by TeamTNT has set its sights on Docker and Kubernetes environments, Redis servers, Postgres databases, Hadoop clusters, Tomcat and Nginx servers, Weave Scope, SSH, and Jupyter applications," Aqua security researchers Ofek Itach and Assaf Morag  said  in a report shared with The Hacker News. "The focus this time seems to be more on infecting systems and testing the botnet, rather than deploying cryptominers for profit." The development arrives a week after the cloud security company  detailed  an intrusion set linked to the TeamTNT group that targets exposed JupyterLab and Docker APIs to deploy the Tsunami malware and hijack system resources to run a cryptocurrency miner. The latest findings suggest a broader campaign and the use of a larger attack infrastructure than previously thought, including various shell sc...

In a sign that cybersecurity researchers continue to be under the radar of malicious actors, a proof-of-concept (PoC) has been discovered on GitHub, concealing a backdoor with a "crafty" persistence method. "In this instance, the PoC is a wolf in sheep's clothing, harboring malicious intent under the guise of a harmless learning tool," Uptycs researchers Nischay Hegde and Siddartha Malladi  said . "Operating as a downloader, it silently dumps and executes a Linux bash script, all the while disguising its operations as a kernel-level process." The  repository  masquerades as a PoC for  CVE-2023-35829 , a recently disclosed high-severity flaw in the Linux kernel. It has since been taken down, but not before it was forked 25 times.  Another PoC  shared by the same account, ChriSanders22, for  CVE-2023-20871 , a privilege escalation bug impacting VMware Fusion, was forked twice. Uptypcs also identified a  second GitHub profile  containing a b...

The U.S. Cybersecurity and Infrastructure Security Agency (CISA) has alerted of two security flaws impacting Rockwell Automation ControlLogix EtherNet/IP (ENIP) communication module models that could be exploited to achieve remote code execution and denial-of-service (DoS). "The results and impact of exploiting these vulnerabilities vary depending on the ControlLogix system configuration, but they could lead to denial or loss of control, denial or loss of view, theft of operational data, or manipulation of control for disruptive or destructive consequences on the industrial process for which the ControlLogix system is responsible," Draogos  said . The list of flaws is as follows - CVE-2023-3595  (CVSS score: 9.8) - An out-of-bounds write flaw impacting 1756 EN2* and 1756 EN3* products that could result in arbitrary code execution with persistence on the target system through maliciously crafted common industrial protocol ( CIP ) messages. CVE-2023-3596  (CVSS score:...

An unnamed Federal Civilian Executive Branch (FCEB) agency in the U.S. detected anomalous email activity in mid-June 2023, leading to Microsoft's discovery of a new China-linked  espionage campaign  targeting two dozen organizations. The details come from a joint cybersecurity advisory released by the U.S. Cybersecurity and Infrastructure Security Agency (CISA) and Federal Bureau of Investigation (FBI) on July 12, 2023. "In June 2023, a Federal Civilian Executive Branch (FCEB) agency identified suspicious activity in their Microsoft 365 (M365) cloud environment," the authorities  said . "Microsoft determined that advanced persistent threat (APT) actors accessed and exfiltrated unclassified Exchange Online Outlook data." While the name of the government agency was not revealed,  CNN  and  the Washington Post  reported it was the U.S. State Department, citing people familiar with the matter. Also targeted were the Commerce Department as well as the e...

SonicWall on Wednesday urged customers of Global Management System (GMS) firewall management and Analytics network reporting engine software to apply the latest fixes to secure against a set of 15 security flaws that could be exploited by a threat actor to circumvent authentication and access sensitive information. Of the 15 shortcomings (tracked from CVE-2023-34123 through CVE-2023-34137), four are rated Critical, four are rated High, and seven are rated Medium in severity. The vulnerabilities were disclosed by NCC Group. The flaws impact on-premise versions of GMS 9.3.2-SP1 and before and Analytics 2.5.0.4-R7 and before. Fixes are available in versions GMS 9.3.3 and Analytics 2.5.2. "The suite of vulnerabilities allows an attacker to view data that they are not normally able to retrieve," SonicWall  said . "This might include data belonging to other users, or any other data that the application itself is able to access. In many cases, an attacker can modify or dele...

Ransomware has emerged as the only cryptocurrency-based crime to grow in 2023, with cybercriminals extorting nearly $175.8 million more than they did a year ago, according to findings from Chainalysis. "Ransomware attackers are on pace for their second-biggest year ever, having extorted at least $449.1 million through June," the blockchain analytics firm  said  in a midyear crypto crime report shared with The Hacker News. "If this pace continues, ransomware attackers will extort $898.6 million from victims in 2023, trailing only 2021's $939.9 million." In contrast, crypto scams have pulled in 77% less revenue than they did through June of 2022, largely driven by the abrupt exit of  VidiLook , which paid users VDL tokens in return for watching digital ads that could then be exchanged for large rewards. So have the inflows to illicit addresses associated with malware, darknet markets, child abuse material, and fraud shops. The development, following a  declin...

Artificial intelligence (AI) holds immense potential for optimizing internal processes within businesses. However, it also comes with legitimate concerns regarding unauthorized use, including data loss risks and legal consequences. In this article, we will explore the risks associated with AI implementation and discuss measures to minimize damages. Additionally, we will examine regulatory initiatives by countries and ethical frameworks adopted by companies to regulate AI. Security risks  AI phishing attacks Cybercriminals can leverage AI in various ways to enhance their phishing attacks and increase their chances of success. Here are some ways AI can be exploited for phishing: -  Automated Phishing Campaigns:  AI-powered tools can automate the creation and dissemination of phishing emails on a large scale. These tools can generate convincing email content, craft personalized messages, and mimic the writing style of a specific individual, making phishing attempts app...
