A suspected Chinese threat actor targeted a large U.S. organization earlier this year as part of a four-month-long intrusion. According to Broadcom-owned Symantec, the first evidence of the malicious activity was detected on April 11, 2024 and continued until August. However, the company doesn't rule out the possibility that the intrusion may have occurred earlier. "The attackers moved laterally across the organization's network, compromising multiple computers," the Symantec Threat Hunter Team said in a report shared with The Hacker News. "Some of the machines targeted were Exchange Servers, suggesting the attackers were gathering intelligence by harvesting emails. Exfiltration tools were also deployed, suggesting that targeted data was taken from the organizations." The name of the organization that was impacted by the persistent attack campaign was not disclosed, but noted that the victim has a significant presence in China. The links to China as ...

The U.S. Cybersecurity and Infrastructure Security Agency (CISA) added multiple security flaws affecting products from Zyxel, North Grid Proself, ProjectSend , and CyberPanel to its Known Exploited Vulnerabilities ( KEV ) catalog, citing evidence of active exploitation in the wild. The list of vulnerabilities is as follows - CVE-2024-51378 (CVSS score: 10.0) - An incorrect default permissions vulnerability that allows for authentication bypass and the execution of arbitrary commands using shell metacharacters in the statusfile property CVE-2023-45727 (CVSS score: 7.5) - An improper restriction of XML External Entity (XXE) reference vulnerability that could allow a remote, unauthenticated attacker to conduct an XXE attack CVE-2024-11680 (CVSS score: 9.8) - An improper authentication vulnerability that allows a remote, unauthenticated attacker to create accounts, upload web shells, and embed malicious JavaScript CVE-2024-11667 (CVSS score: 7.5) - A path traversal vulnerabilit...

Most microsegmentation projects fail before they even get off the ground—too complex, too slow, too disruptive. But Andelyn Biosciences proved it doesn't have to be that way.  Microsegmentation: The Missing Piece in Zero Trust Security   Security teams today are under constant pressure to defend against increasingly sophisticated cyber threats. Perimeter-based defenses alone can no longer provide sufficient protection as attackers shift their focus to lateral movement within enterprise networks. With over 70% of successful breaches involving attackers moving laterally, organizations are rethinking how they secure internal traffic.  Microsegmentation has emerged as a key strategy in achieving Zero Trust security by restricting access to critical assets based on identity rather than network location. However, traditional microsegmentation approaches—often involving VLAN reconfigurations, agent deployments, or complex firewall rules—tend to be slow, operationally disrupt...

The North Korea-aligned threat actor known as Kimsuky has been linked to a series of phishing attacks that involve sending email messages that originate from Russian sender addresses to ultimately conduct credential theft. "Phishing emails were sent mainly through email services in Japan and Korea until early September," South Korean cybersecurity company Genians said . "Then, from mid-September, some phishing emails disguised as if they were sent from Russia were observed." This entails the abuse of VK's Mail.ru email service, which supports five different alias domains, including mail.ru, internet.ru, bk.ru, inbox.ru, and list.ru. Genians said it has observed the Kimsuky actors leveraging all the aforementioned sender domains for phishing campaigns that masquerade as financial institutions and internet portals like Naver. Other phishing attacks have entailed sending messages that mimic Naver's MYBOX cloud storage service and aim to trick users into ...

Cybersecurity researchers are warning about malicious email campaigns leveraging a phishing-as-a-service ( PhaaS ) toolkit called Rockstar 2FA with an aim to steal Microsoft 365 account credentials. "This campaign employs an AitM [adversary-in-the-middle] attack, allowing attackers to intercept user credentials and session cookies, which means that even users with multi-factor authentication (MFA) enabled can still be vulnerable," Trustwave researchers Diana Solomon and John Kevin Adriano said . Rockstar 2FA is assessed to be an updated version of the DadSec (aka Phoenix) phishing kit. Microsoft is tracking the developers and distributors of the Dadsec PhaaS platform under the moniker Storm-1575 . Like its predecessors, the phishing kit is advertised via services like ICQ, Telegram, and Mail.ru under a subscription model for $200 for two weeks (or $350 for a month), allowing cyber criminals with little-to-no technical expertise to mount campaigns at scale. Some of the...

Cybersecurity researchers have shed light on what has been described as the first Unified Extensible Firmware Interface (UEFI) bootkit designed for Linux systems. Dubbed Bootkitty by its creators who go by the name BlackCat, the bootkit is assessed to be a proof-of-concept (PoC) and there is no evidence that it has been put to use in real-world attacks. Also tracked as IranuKit , it was uploaded to the VirusTotal platform on November 5, 2024. "The bootkit's main goal is to disable the kernel's signature verification feature and to preload two as yet unknown ELF binaries via the Linux init process (which is the first process executed by the Linux kernel during system startup)," ESET researchers Martin Smolár and Peter Strýček said . The development is significant as it heralds a shift in the cyber threat landscape where UEFI bootkits are no longer confined to Windows systems alone . It's worth noting that Bootkitty is signed by a self-signed certificate, a...

Multi-stage cyber attacks, characterized by their complex execution chains, are designed to avoid detection and trick victims into a false sense of security. Knowing how they operate is the first step to building a solid defense strategy against them. Let's examine real-world examples of some of the most common multi-stage attack scenarios that are active right now. URLs and Other Embedded Content in Documents Attackers frequently hide malicious links within seemingly legitimate documents, such as PDFs or Word files. Upon opening the document and clicking the embedded link, users are directed to a malicious website. These sites often employ deceptive tactics to get the victim to download malware onto their computer or share their passwords. Another popular type of embedded content is QR codes. Attackers conceal malicious URLs within QR codes and insert them into documents. This strategy forces users to turn to their mobile devices to scan the code, which then directs them to ph...

When CVEs go viral, separating critical vulnerabilities from the noise is essential to protecting your organization.

The U.S. Cybersecurity and Infrastructure Security Agency (CISA) on Monday added a now-patched critical security flaw impacting Array Networks AG and vxAG secure access gateways to its Known Exploited Vulnerabilities ( KEV ) catalog following reports of active exploitation in the wild. The vulnerability, tracked as CVE-2023-28461 (CVSS score: 9.8), concerns a case of missing authentication that could be exploited to achieve arbitrary code execution remotely. Fixes (version 9.4.0.484) for the security shortcoming were released by the network hardware vendor in March 2023.  "Array AG/vxAG remote code execution vulnerability is a web security vulnerability that allows an attacker to browse the filesystem or execute remote code on the SSL VPN gateway using flags attribute in HTTP header without authentication," Array Networks said. "The product can be exploited through a vulnerable URL." The inclusion to KEV catalog comes shortly after cybersecurity company Trend...

Dive into the evolution of phishing and malware evasion techniques and understand how attackers are using increasingly sophisticated methods to bypass security measures. The Evolution of Phishing Attacks "I really like the saying that 'This is out of scope' said no hacker ever. Whether it's tricks, techniques or technologies, hackers will do anything to evade detection and make sure their attack is successful," says Etay Maor, Chief Security Strategist at Cato Networks and member of Cato CTRL . Phishing attacks have transformed significantly over the years. 15-20 years ago, simple phishing sites were sufficient for capturing the crown jewels of the time - credit card details. Today, attacks and defense methods have become much more sophisticated, as we'll detail below. "This is also the time where the "cat-and-mouse" attack-defense game began," says Tal Darsan, Security Manager and member of Cato CTRL. At the time, a major defense technique against credit card phishing sites inv...

Government agencies and non-governmental organizations in the United States have become the target of a nascent China state threat actor known as Storm-2077. The adversary, believed to be active since at least January 2024, has also conducted cyber attacks against the Defense Industrial Base (DIB), aviation, telecommunications, and financial and legal services across the world, Microsoft said . The activity cluster, the company added, overlaps with a threat group that Recorded Future's Insikt Group is tracking as TAG-100 . Attack chains have involved targeting various internet-facing edge devices using publicly available exploits to gain initial access and drop Cobalt Strike as well as open-source malware such as Pantegana and Spark RAT, the cybersecurity company noted back in July. "Over the past decade, following numerous government indictments and the public disclosure of threat actors' activities, tracking and attributing cyber operations originating from China has b...

Cybersecurity researchers have discovered two malicious packages uploaded to the Python Package Index (PyPI) repository that impersonated popular artificial intelligence (AI) models like OpenAI ChatGPT and Anthropic Claude to deliver an information stealer called JarkaStealer. The packages, named gptplus and claudeai-eng , were uploaded by a user named " Xeroline " in November 2023, attracting 1,748 and 1,826 downloads, respectively. Both libraries are no longer available for download from PyPI. "The malicious packages were uploaded to the repository by one author and, in fact, differed from each other only in name and description," Kaspersky said in a post. The packages purported to offer a way to access GPT-4 Turbo API and Claude AI API, but harbored malicious code that initiated the deployment of the malware upon installation. Specifically, the "__init__.py" file in these packages contained Base64-encoded data that incorporated code to download ...

The China-aligned advanced persistent threat (APT) actor known as Gelsemium has been observed using a new Linux backdoor dubbed WolfsBane as part of cyber attacks likely targeting East and Southeast Asia. That's according to findings from cybersecurity firm ESET based on multiple Linux samples uploaded to the VirusTotal platform from Taiwan, the Philippines, and Singapore in March 2023. WolfsBane has been assessed to be a Linux version of the threat actor's Gelsevirine backdoor, a Windows malware put to use as far back as 2014. Also discovered by the company is another previously undocumented implant named FireWood that's connected to a different malware toolset known as Project Wood . FireWood has been attributed to Gelsemium with low confidence, given the possibility that it could be shared by multiple China-linked hacking crews. "The goal of the backdoors and tools discovered is cyber espionage targeting sensitive data such as system information, user crede...

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....

Cybersecurity researchers have shed light on a new stealthy malware loader called BabbleLoader that has been observed in the wild delivering information stealer families such as WhiteSnake and Meduza . BabbleLoader is an "extremely evasive loader, packed with defensive mechanisms, that is designed to bypass antivirus and sandbox environments to deliver stealers into memory," Intezer security researcher Ryan Robinson said in a report published Sunday. Evidence shows that the loader is being used in several campaigns targeting both English and Russian-speaking individuals, primarily singling out users looking for generic cracked software as well as business professionals in finance and administration by passing it off as accounting software. Loaders have become an increasingly prevalent method to deliver malware, like stealers or ransomware, often acting as the first stage in an attack chain in a manner that sidesteps traditional antivirus defenses by incorporating a be...
