The U.S. Cybersecurity and Infrastructure Security Agency (CISA) on Monday issued an alert warning of bad actors actively leveraging commercial spyware and remote access trojans (RATs) to target users of mobile messaging applications. "These cyber actors use sophisticated targeting and social engineering techniques to deliver spyware and gain unauthorized access to a victim's messaging app, facilitating the deployment of additional malicious payloads that can further compromise the victim's mobile device," the agency said . CISA cited as examples multiple campaigns that have come to light since the start of the year. Some of them include - The targeting of the Signal messaging app by multiple Russia-aligned threat actors by taking advantage of the service's "linked devices" feature to hijack target user accounts Android spyware campaigns codenamed ProSpy and ToSpy that impersonate apps like Signal and ToTok to target users in the United Arab Emi...

Cybersecurity researchers have discovered five vulnerabilities in Fluent Bit , an open-source and lightweight telemetry agent, that could be chained to compromise and take over cloud infrastructures. The security defects "allow attackers to bypass authentication, perform path traversal, achieve remote code execution, cause denial-of-service conditions, and manipulate tags," Oligo Security said in a report shared with The Hacker News. Successful exploitation of the flaws could enable attackers to disrupt cloud services, manipulate data, and burrow deeper into cloud and Kubernetes infrastructure. The list of identified vulnerabilities is as follows - CVE-2025-12972 - A path traversal vulnerability stemming from the use of unsanitized tag values to generate output filenames, making it possible to write or overwrite arbitrary files on disk, enabling log tampering and remote code execution. CVE-2025-12970 - A stack buffer overflow vulnerability in the Docker Metrics inp...

Multiple security vendors are sounding the alarm about a second wave of attacks targeting the npm registry in a manner that's reminiscent of the Shai-Hulud attack . The new supply chain campaign, dubbed Sha1-Hulud , has compromised hundreds of npm packages, according to reports from Aikido , HelixGuard , JFrog , Koi Security , ReversingLabs , SafeDep , Socket , Step Security , and Wiz . The trojanized npm packages were uploaded to npm between November 21 and 23, 2025. The attack has impacted popular packages from Zapier, ENS Domains, PostHog, and Postman, among others. "The campaign introduces a new variant that executes malicious code during the preinstall phase, significantly increasing potential exposure in build and runtime environments," Wiz researchers Hila Ramati, Merav Bar, Gal Benmocha, and Gili Tikochinski said. Like the Shai-Hulud attack that came to light in September 2025, the latest activity also publishes stolen secrets to GitHub, this time with the rep...

This week saw a lot of new cyber trouble. Hackers hit Fortinet and Chrome with new 0-day bugs. They also broke into supply chains and SaaS tools. Many hid inside trusted apps, browser alerts, and software updates. Big firms like Microsoft, Salesforce, and Google had to react fast — stopping DDoS attacks, blocking bad links, and fixing live flaws. Reports also showed how fast fake news, AI risks, and attacks on developers are growing. Here’s what mattered most in security this week. ⚡ Threat of the Week Fortinet Warns of Another Silently Patched and Actively Exploited FortiWeb Flaw — Fortinet has warned that a new security flaw in FortiWeb has been exploited in the wild. The medium-severity vulnerability, tracked as CVE-2025-58034, carries a CVSS score of 6.7 out of a maximum of 10.0. It has been addressed in version 8.0.2. "An Improper Neutralization of Special Elements used in an OS Command ('OS Command Injection') vulnerability [CWE-78] in FortiWeb may allow an a...

New research from CrowdStrike has revealed that DeepSeek's artificial intelligence (AI) reasoning model DeepSeek-R1 produces more security vulnerabilities in response to prompts that contain topics deemed politically sensitive by China. "We found that when DeepSeek-R1 receives prompts containing topics the Chinese Communist Party (CCP) likely considers politically sensitive, the likelihood of it producing code with severe security vulnerabilities increases by up to 50%," the cybersecurity company said . The Chinese AI company previously attracted national security concerns, leading to a ban in many countries. Its open-source DeepSeek-R1 model was also found to censor topics considered sensitive by the Chinese government, refusing to answer questions about the Great Firewall of China or the political status of Taiwan, among others. In a statement released earlier this month, Taiwan's National Security Bureau warned citizens to be vigilant when using Chinese-m...
