The China-linked threat actor behind the zero-day exploitation of security flaws in Microsoft Exchange servers in January 2021 has shifted its tactics to target the information technology (IT) supply chain as a means to obtain initial access to corporate networks. That's according to new findings from the Microsoft Threat Intelligence team, which said the Silk Typhoon (formerly Hafnium) hacking group is now targeting IT solutions like remote management tools and cloud applications to obtain a foothold. "After successfully compromising a victim, Silk Typhoon uses the stolen keys and credentials to infiltrate customer networks where they can then abuse a variety of deployed applications, including Microsoft services and others, to achieve their espionage objectives," the tech giant said in a report published today. The adversarial collective is assessed to be "well-resourced and technically efficient," swiftly putting to use exploits for zero-day vulnerabil...

USB drive attacks constitute a significant cybersecurity risk, taking advantage of the everyday use of USB devices to deliver malware and circumvent traditional network security measures. These attacks lead to data breaches, financial losses, and operational disruptions, with lasting impacts on an organization's reputation. An example is the Stuxnet worm discovered in 2010, a malware designed to target industrial control systems, specifically Iran's nuclear enrichment facilities. It exploited multiple zero-day vulnerabilities and spread primarily through USB drives, making it one of the first examples of a cyberattack with real-world physical effects. Stuxnet exposed the risks of removable media and raised global awareness of cybersecurity threats to critical infrastructure. How USB drive attacks propagate Attackers use various methods to deliver malicious payloads via USB drives, targeting individuals and organizations.  Drop attacks : Infected USB drives are deliberatel...

The threat actor known as Dark Caracal has been attributed to a campaign that deployed a remote access trojan called Poco RAT in attacks targeting Spanish-speaking targets in Latin America in 2024. The findings come from Russian cybersecurity company Positive Technologies, which described the malware as loaded with a "full suite of espionage features." "It could upload files, capture screenshots, execute commands, and manipulate system processes," researchers Denis Kazakov and Sergey Samokhin said in a technical report published last week. Poco RAT was previously documented by Cofense in July 2024, detailing the phishing attacks aimed at mining, manufacturing, hospitality, and utilities sectors. The infection chains are characterized by the use of finance-themed lures that trigger a multi-step process to deploy the malware. While the campaign was not attributed to any threat at that time, Positive Technologies said it identified tradecraft overlaps with Dar...

While phishing and ransomware dominate headlines, another critical risk quietly persists across most enterprises: exposed Git repositories leaking sensitive data. A risk that silently creates shadow access into core systems Git is the backbone of modern software development, hosting millions of repositories and serving thousands of organizations worldwide. Yet, amid the daily hustle of shipping code, developers may inadvertently leave behind API keys, tokens, or passwords in configuration files and code files, effectively handing attackers the keys to the kingdom. This isn't just about poor hygiene; it's a systemic and growing supply chain risk. As cyber threats become more sophisticated, so do compliance requirements. Security frameworks like NIS2, SOC2, and ISO 27001 now demand proof that software delivery pipelines are hardened and third-party risk is controlled. The message is clear: securing your Git repositories is no longer optional, it's essential. Below, we look at the ris...

Google has announced the rollout of artificial intelligence (AI)-powered scam detection features to secure Android device users and their personal information. "These features specifically target conversational scams, which can often appear initially harmless before evolving into harmful situations," Google said . "And more phone calling scammers are using spoofing techniques to hide their real numbers and pretend to be trusted companies." The company said it has partnered with financial institutions to better understand the nature of scams customers are encountering, thereby allowing it to devise AI models that can flag suspicious patterns and deliver real-time warnings over the course of a conversation without sacrificing user privacy. These models run completely on-device , alerting users in the event of a likely scam. Users then have an option to either dismiss or report and block the sender. The setting is enabled by default and applies only to conversatio...

The threat actor known as Lotus Panda has been observed targeting government, manufacturing, telecommunications, and media sectors in the Philippines, Vietnam, Hong Kong, and Taiwan with updated versions of a known backdoor called Sagerunex . "Lotus Blossom has been using the Sagerunex backdoor since at least 2016 and is increasingly employing long-term persistence command shells and developing new variants of the Sagerunex malware suite," Cisco Talos researcher Joey Chen said in an analysis published last week. Lotus Panda, also known as Billbug, Bronze Elgin, Lotus Blossom, Spring Dragon, and Thrip, is a suspected Chinese hacking crew that's active since at least 2009. The threat actor was first exposed by Palo Alto Networks Unit 42 in June 2015 and later by Broadcom-owned Symantec three years later. In late 2022, Symantec detailed the threat actor's attack on a digital certificate authority as well as government and defense agencies located in different c...

The rapid adoption of cloud services, SaaS applications, and the shift to remote work have fundamentally reshaped how enterprises operate. These technological advances have created a world of opportunity but also brought about complexities that pose significant security threats. At the core of these vulnerabilities lies Identity —the gateway to enterprise security and the number one attack vector for bad actors. Explore the importance of modernizing Identity strategies and the benefits of centralizing Identity within your security ecosystem to safeguard your organization from costly breaches while enhancing operational efficiency. The rise of fragmented tech stacks Gone are the days when enterprises relied on a single solution tied to a comprehensive license agreement. Businesses today prioritize agility and performance, opting for "best-in-breed" solutions that patch together fragmented tech ecosystems. While these advanced tech stacks provide flexibility, they also create signif...

Cybersecurity researchers are alerting of an ongoing malicious campaign targeting the Go ecosystem with typosquatted modules that are designed to deploy loader malware on Linux and Apple macOS systems. "The threat actor has published at least seven packages impersonating widely used Go libraries, including one (github[.]com/shallowmulti/hypert) that appears to target financial-sector developers," Socket researcher Kirill Boychenko said in a new report. "These packages share repeated malicious filenames and consistent obfuscation techniques, suggesting a coordinated threat actor capable of pivoting rapidly." While all of them continue to be available on the official package repository, their corresponding GitHub repositories barring "github[.]com/ornatedoctrin/layout" are no longer accessible. The list of offending Go packages is below - shallowmulti/hypert (github.com/shallowmulti/hypert) shadowybulk/hypert (github.com/shadowybulk/hypert) belate...

Threat actors deploying the Black Basta and CACTUS ransomware families have been found to rely on the same BackConnect (BC) module for maintaining persistent control over infected hosts, a sign that affiliates previously associated with Black Basta may have transitioned to CACTUS. "Once infiltrated, it grants attackers a wide range of remote control capabilities, allowing them to execute commands on the infected machine," Trend Micro said in a Monday analysis. "This enables them to steal sensitive data, such as login credentials, financial information, and personal files." It's worth noting that details of the BC module, which the cybersecurity company is tracking as QBACKCONNECT owing to overlaps with the QakBot loader, was first documented in late January 2025 by both Walmart's Cyber Intelligence team and Sophos, the latter of which has designated the cluster the name STAC5777.  Over the past year, Black Basta attack chains have increasingly leve...

Broadcom has released security updates to address three actively exploited security flaws in VMware ESXi, Workstation, and Fusion products that could lead to code execution and information disclosure.
