Malicious actors are exploiting misconfigured JupyterLab and Jupyter Notebooks to conduct stream ripping and enable sports piracy using live streaming capture tools. The attacks involve the hijack of unauthenticated Jupyter Notebooks to establish initial access, and perform a series of actions designed to facilitate illegal live streaming of sports events, Aqua said in a report shared with The Hacker News. The covert piracy campaign within interactive environments widely used for data science applications was discovered by the cloud security firm following an attack against its honeypots. "First, the attacker updated the server, then downloaded the tool FFmpeg ," said Assaf Morag, director of threat intelligence at cloud security firm Aqua. "This action alone is not a strong enough indicator for security tools to flag malicious activity." "Next, the attacker executed FFmpeg to capture live streams of sports events and redirected them to their server....

Privileged accounts are well-known gateways for potential security threats. However, many organizations focus solely on managing privileged access—rather than securing the accounts and users entrusted with it. This emphasis is perhaps due to the persistent challenges of Privileged Access Management (PAM) deployments. Yet, as the threat landscape evolves, so must organizational priorities. To prevent trust from becoming a liability, the next step in securing privileged access must become a critical focus. In this blog, we explore why managing privileged access alone is insufficient and provide actionable insights to help you craft a security-first strategy for privileged access. The Evolution of PAM Privileged Access Management (PAM) has long been a cornerstone of securing an organization’s privileged users and critical resources. PAM’s primary goal is to control, monitor, and safeguard privileged accounts, which often have elevated access to critical systems and data. These accou...

Cybersecurity researchers have shed light on a Linux variant of a relatively new ransomware strain called Helldown, suggesting that the threat actors are broadening their attack focus. "Helldown deploys Windows ransomware derived from the LockBit 3.0 code," Sekoia said in a report shared with The Hacker News. "Given the recent development of ransomware targeting ESX, it appears that the group could be evolving its current operations to target virtualized infrastructures via VMware." Helldown was first publicly documented by Halcyon in mid-August 2024, describing it as an "aggressive ransomware group" that infiltrates target networks by exploiting security vulnerabilities. Some of the prominent sectors targeted by the cybercrime group include IT services, telecommunications, manufacturing, and healthcare. Like other ransomware crews, Helldown is known for leveraging data leak sites to pressure victims into paying ransoms by threatening to publish s...

U.S. telecoms giant T-Mobile has confirmed that it was also among the companies that were targeted by Chinese threat actors to gain access to valuable information. The adversaries, tracked as Salt Typhoon , breached the company as part of a "monthslong campaign" designed to harvest cellphone communications of "high-value intelligence targets." It's not clear what information was taken, if any, during the malicious activity. "T-Mobile is closely monitoring this industry-wide attack, and at this time, T-Mobile systems and data have not been impacted in any significant way, and we have no evidence of impacts to customer information," a spokesperson for the company was quoted as saying to The Wall Street Journal. "We will continue to monitor this closely, working with industry peers and the relevant authorities." With the latest development, T-Mobile has joined a list of major organizations like AT&T, Verizon, and Lumen Technologies that...

Now-patched security flaws impacting Progress Kemp LoadMaster and VMware vCenter Server have come under active exploitation in the wild, it has emerged. The U.S. Cybersecurity and Infrastructure Security Agency (CISA) on Monday added CVE-2024-1212 (CVSS score: 10.0), a maximum-severity security vulnerability in Progress Kemp LoadMaster to its Known Exploited Vulnerabilities ( KEV ) catalog. It was addressed by Progress Software back in February 2024 . "Progress Kemp LoadMaster contains an OS command injection vulnerability that allows an unauthenticated, remote attacker to access the system through the LoadMaster management interface, enabling arbitrary system command execution," the agency said. Rhino Security Labs, which discovered and reported the flaw, said successful exploitation enables command execution on LoadMaster should an attacker have access to the administrator web user interface, granting them full access to the load balancer. CISA's addition of ...
