A sophisticated malware campaign targeting WhatsApp users has been observed since February 2026. The attack chain begins with malicious Visual Basic Script files sent via WhatsApp messages, which, when executed, initiate a multi-stage infection process. The malware uses renamed Windows utilities, retrieves payloads from trusted cloud services, and installs malicious MSI packages. The campaign employs social engineering, stealth techniques, and cloud-based payload hosting to establish persistence and escalate privileges on victim systems. The attackers utilize legitimate tools and trusted platforms to reduce visibility and increase the likelihood of successful execution. The final stage involves the delivery of unsigned MSI installers that enable remote access to compromised systems.
A sophisticated phishing campaign targeting LinkedIn users has been identified. The attack uses fake LinkedIn message notifications to lure victims into clicking on malicious links. The emails closely mimic legitimate LinkedIn communications, including spoofed display names and formatting. Upon clicking, users are redirected to a convincing but fraudulent LinkedIn login page designed to steal credentials. The phishing page uses a deceptive domain name similar to 'LinkedIn' to further trick users. This campaign demonstrates the evolving tactics of cybercriminals in exploiting human trust and curiosity. The analysis emphasizes the importance of vigilance, source verification, and caution when interacting with seemingly routine notifications.

Ransomware is increasingly targeting home backups on NAS, cloud storage, and external drives. Here’s how these attacks work, and how to keep your family photos and documents safe.
An unknown threat actor compromised the npm account of an axios maintainer, publishing two malicious versions of the package. These versions introduced a dependency on plain-crypto-js, a newly created malicious package. Despite quick removal, axios's widespread usage led to rapid exposure. The malicious package includes a dropper that downloads and executes platform-specific second-stage payloads, functioning as remote access trojans. These payloads can execute remote shells, inject binaries, browse directories, list processes, and perform system reconnaissance. Organizations are advised to audit their environments, remove malicious artifacts, rotate exposed credentials, investigate potential compromise paths, and monitor for suspicious activity.
A lot of the information seen on DShield honeypots [1] is repeated bot traffic, especially when looking at the Cowrie [2] telnet and SSH sessions. However, how long a session lasts, how many commands are run per session and what the last commands run before a session disconnects can vary. Some of this information could help indicate whether a session is automated and if a honeypot was fingerprinted. This information can also be used to find more interesting honeypot sessions.
Key Takeaways What Happened AI assistants now handle some of the most sensitive data people own. Users discuss symptoms and medical history. They ask questions about taxes, debts, and personal finances, upload PDFs, contracts, lab results, and identity-rich documents that contain names, addresses, account details, and private records. That trust depends on a simple expectation: […] The post ChatGPT Data Leakage via a Hidden Outbound Channel in the Code Execution Runtime appeared first on Check Point Research .
This analysis examines multiple data leaks attributed to BreachForums between 2022 and 2026, focusing on distinguishing between leak publication dates and actual data timelines. The study covers four datasets associated with different domain names (.vc, .co, .hn, .bf) used by the platform. Each dataset is analyzed based on publication date, format, database structure, and the 'lastactive' field in the user table. The analysis reveals that the domain associated with a leak does not necessarily indicate the timing of the compromise, but rather the context of data collection. The article emphasizes the importance of differentiating between publication date and actual data timeline to avoid misattribution in cyber threat intelligence activities.
A new phishing campaign is targeting TikTok for Business accounts using adversary-in-the-middle (AitM) techniques. The attackers employ Cloudflare Turnstile to evade detection and create convincing lookalike pages impersonating TikTok for Business or Google Careers. Victims are tricked into clicking malicious links, leading to credential theft. The campaign aims to seize control of business accounts, which can be used for malvertising and malware distribution. Multiple domains are involved in hosting the phishing pages. Additionally, a separate campaign using SVG file attachments to deliver malware has been observed in Venezuela, with potential links to BianLian ransomware activity.
This analysis examines how threat actors abuse Keitaro, an advertising performance tracker, for various malicious purposes. The report covers a wide range of threats, including malware delivery, phishing, scams, and illegal content distribution. Key findings include the use of Keitaro for cloaking and traffic distribution in malvertising campaigns, spam operations leveraging Keitaro for cryptocurrency wallet draining, and the abuse of Keitaro in investment scams. The report also highlights specific threat actors and their tactics, such as domain hijacking for adult content delivery and the use of fake arrests as clickbait for investment scams. Overall, the analysis demonstrates how Keitaro's features make it attractive to cybercriminals seeking to maximize their reach with minimal effort.
