GreyNoise has observed a significant surge in login scanning activity targeting Palo Alto Networks PAN-OS GlobalProtect portals. Over the last 30 days, nearly 24,000 unique IP addresses have attempted to access these portals. The pattern suggests a coordinated effort to probe network defenses and identify exposed or vulnerable systems, potentially as a precursor to targeted exploitation.
Recent patterns observed by GreyNoise suggest that this activity may signal the emergence of new vulnerabilities in the near future:
“Over the past 18 to 24 months, we’ve observed a consistent pattern of deliberate targeting of older vulnerabilities or well-worn attack and reconnaissance attempts against specific technologies,” said Bob Rudis, VP of Data Science at GreyNoise. “These patterns often coincide with new vulnerabilities emerging 2 to 4 weeks later.”
Millions of Americans have downloaded apps that secretly route their internet traffic through Chinese companies, according to an investigation by the Tech Transparency Project (TTP), including several that were recently owned by a sanctioned firm with links to China’s military.
TTP’s investigation found that one in five of the top 100 free virtual private networks in the U.S. App Store during 2024 were surreptitiously owned by Chinese companies, which are obliged to hand over their users’ browsing data to the Chinese government under the country’s national security laws. Several of the apps traced back to Qihoo 360, a firm declared by the Defense Department to be a “Chinese Military Company." Qihoo did not respond to questions about its app-related holdings.
OUTLAW is a persistent yet unsophisticated auto-propagating coinminer package observed across multiple versions over the past few years [1], [2], [3], [4]. Despite lacking stealth and advanced evasion techniques, it remains active and effective by leveraging simple but impactful tactics such as SSH brute-forcing, SSH key and cron-based persistence, and manually modified commodity miners and IRC channels. This persistence highlights how botnet operators can achieve widespread impact without relying on sophisticated techniques.
Kidflix, one of the largest paedophile platforms in the world, has been shut down in an international operation against child sexual exploitation. The investigation was supported by Europol and led by the State Criminal Police of Bavaria (Bayerisches Landeskriminalamt) and the Bavarian Central Office for the Prosecution of Cybercrime (ZCB). Over 35 countries worldwide participated in the operation. almost 1 400 suspects worldwide. So far, 79 of these individuals have been arrested...
By leveraging Microsoft Security Copilot to expedite the vulnerability discovery process, Microsoft Threat Intelligence uncovered several vulnerabilities in multiple open-source bootloaders, impacting all operating systems relying on Unified Extensible Firmware Interface (UEFI) Secure Boot as well as IoT devices. The vulnerabilities found in the GRUB2 bootloader (commonly used as a Linux bootloader) and U-boot and Barebox bootloaders (commonly used for embedded systems), could allow threat actors to gain and execute arbitrary code.
Enterprise file transfer solutions are critical infrastructure for many organizations, facilitating secure data exchange between systems and users. CrushFTP, a widely used multi-protocol file transfer server, offers an extensive feature set including Amazon S3-compatible API access. However, a critical vulnerability (CVE-2025-2825) was discovered in versions 10.0.0 through 10.8.3 and 11.0.0 through 11.3.0 that allows unauthenticated attackers to bypass authentication and gain unauthorized access
Apple finally adds TCC events to Endpoint Security!
Since the majority of macOS malware circumvents TCC through explicit user approval, it would be incredibly helpful for any security tool to detect this — and possibly override the user’s risky decision. Until now the best (only?) option was to ingest log messages generated by the TCC subsystem. This approach was implemented in a tool dubbed Kronos, written by Calum Hall Luke Roberts (now, of Phorion fame). Unfortunately, as they note, this approach did have it drawbacks:
