New Tooling

• Your IP Address Might Be Someone Else's Problem (And Here's How To Find Out)
  "We built something new at GreyNoise Labs, and it started with a question we kept hearing: “How do I know if my home network has been compromised?” It’s not a theoretical concern. Over the past year, residential proxy networks have exploded and have been turning home internet connections into exit points for other people’s traffic. Sometimes folks knowingly install software that does this in exchange for a few dollars. More often, malware sneaks onto devices, usually via nefarious apps or browser extensions, and quietly turns them into nodes in someone else’s infrastructure."

• Tomiris Wreaks Havoc: New Tools And Techniques Of The APT Group
  "While tracking the activities of the Tomiris threat actor, we identified new malicious operations that began in early 2025. These attacks targeted foreign ministries, intergovernmental organizations, and government entities, demonstrating a focus on high-value political and diplomatic infrastructure. In several cases, we traced the threat actor’s actions from initial infection to the deployment of post-exploitation frameworks. These attacks highlight a notable shift in Tomiris’s tactics, namely the increased use of implants that leverage public services (e.g., Telegram and Discord) as command-and-control (C2) servers. This approach likely aims to blend malicious traffic with legitimate service activity to evade detection by security tools."

• Bootstrap Script Exposes PyPI To Domain Takeover Attacks
  "ReversingLabs researchers have discovered vulnerable code in legacy Python packages that could make possible an attack on the Python Package Index (PyPI) via a domain compromise. Although the vulnerable code is mostly unused in modern development environments, it may still be used in legacy production. RL Spectra Assure Community’s machine learning model, which detects packages with behaviors similar to known malware, found the vulnerability in bootstrap files for a build tool that installs the Python package distribute and performs other tasks in the bootstrapping process."

• Inside The GitHub Infrastructure Powering North Korea’s Contagious Interview Npm Attacks
  "The Socket Threat Research Team continues to track North Korea’s Contagious Interview operation as it systematically infiltrates the npm ecosystem. Since we last reported on this campaign, it has added at least 197 more malicious npm packages and over 31,000 additional downloads, with state-sponsored threat actors targeting blockchain and Web3 developers through fake job interviews and “test assignments”. This sustained tempo makes Contagious Interview one of the most prolific campaigns exploiting npm, and it shows how thoroughly North Korean threat actors have adapted their tooling to modern JavaScript and crypto-centric development workflows."

• PostHog Admits Shai-Hulud 2.0 Was Its Biggest Ever Security Bungle
  "PostHog says the Shai-Hulud 2.0 npm worm compromise was "the largest and most impactful security incident" it's ever experienced after attackers slipped malicious releases into its JavaScript SDKs and tried to auto-loot developer credentials. In a postmortem released by PostHog, one of the various package maintainers impacted by Shai-Hulud 2.0, the company says contaminated packages – which included core SDKs like posthog-node, posthog-js, and posthog-react-native – contained a pre-install script that ran automatically when the software was installed. That script ran TruffleHog to scan for credentials, exfiltrated any found secrets to new public GitHub repositories, then used stolen npm credentials to publish further malicious packages – enabling the worm to spread."

• Fragmented Tooling Slows Vulnerability Management
  "Security leaders know vulnerability backlogs are rising, but new data shows how quickly the gap between exposures and available resources is widening, according to a new report by Hackuity. Organizations use a formalized approach to manage vulnerabilities, but their tooling remains fragmented. Respondents rely on an average of four detection tools, and cloud or container configuration audits are the most common at 85%. This mix suggests broad coverage, but it also explains why teams struggle with visibility, correlation of findings, and consistent prioritization."

• • Is Zendesk Scattered Lapsus$ Hunters’ Latest Campaign Target?
    "ReliaQuest has uncovered indications of a potential new campaign from the notorious threat collective “Scattered Lapsus$ Hunters,” this time targeting users of the customer support software Zendesk. ReliaQuest’s Threat Research team identified Zendesk-related domains, including more than 40 typosquatted domains and impersonating URLs, created within the past six months. These domains, such as znedesk[.]com or vpn-zendesk[.]com, are clearly designed to mimic legitimate Zendesk environments. Some host phishing pages, like fake single sign-on (SSO) portals that appear before Zendesk authentication. It’s a classic tactic probably aimed at stealing credentials from unsuspecting users. We also identified Zendesk-related impersonating domains that contained multiple different organizations’ names or brands within the URL, making it even more likely that unsuspecting users would trust and click on these links."

An attacker briefly opened a pull request that modified a script executed via pull_request_target, exfiltrated a bot personal access token from CI, then used that access to steal additional GitHub secrets including an npm publish token and ship malicious versions of several PostHog SDKs. PostHog has since revoked credentials, tightened workflow reviews, moved to trusted publishing, and reworked its secrets management. Their write up highlights how subtle CI workflow choices can create a path from untrusted contributions to package release credentials."

• Cybersecurity Is Now a Core Business Discipline
  "Cyber risk has become the background noise of modern business. We’re seeing nearly two thousand attacks per organization per week in the first quarter of 2025—a 47% rise year-on-year. That surge reflects two realities moving at once: attacks are genuinely increasing because it’s easier and cheaper than ever to mount them, and defenders are getting better at spotting what previously slipped under the radar. In other words, the problem is growing and we’re measuring it more honestly."

• The Golden Scale: 'Tis The Season For Unwanted Gifts
  "In October 2025, we published two Insights blogs on threat activity affiliated with the cybercriminal alliance known as Scattered LAPSUS$ Hunters (SLSH). After a few weeks of apparent inactivity, the threat actors have returned with a vengeance based on open-source reporting and conversations obtained from a new Telegram channel (scattered LAPSUS$ hunters part 7). This latest Insights threat blog will detail several notable observations made by Unit 42 since mid-November, and prepares organizations as we head into the holiday season."

• Behind The Bargains: Why Phishing Peaks On Black Friday
  "Black Friday has evolved into one of the most active shopping periods of the year. No longer is it just one day of shopping after Thanksgiving; the sales have now turned into a full week of high-volume promotions, beginning before Thanksgiving and stretching through Black Friday and Cyber Monday, with many retailers extending deals even longer. Unsurprisingly, this surge in digital activity is very attractive for threat actors."

• Sumsub’s Annual Report: Fraud Shifts To Complex Multi-Step Schemes In 2025, Agentic AI Scams Poised To Surge In 2026
  "Sumsub today released its Identity Fraud Report 2025–2026, analyzing millions of verification checks and 4,000,000+ fraud attempts between 2024–2025*. The study blends global and regional dynamics from internal data with findings from Sumsub’s Fraud Exposure Survey 2025, featuring responses from 300+ risk professionals and 1,200+ end users. In 2024, the rise of fraud-as-a-service platforms and ready-made toolkits “democratized” identity crime, making it widely accessible to non-tech-savvy fraudsters. In 2025, that trend matured into the Sophistication Shift: fewer but more professionalized operations designed for higher-impact damage."
