In what's the latest instance of a software supply chain attack, unknown threat actors managed to compromise Toptal's GitHub organization account and leveraged that access to publish 10 malicious packages to the npm registry. The packages contained code to exfiltrate GitHub authentication tokens and destroy victim systems, Socket said in a report published last week. In addition, 73 repositories associated with the organization were made public. The list of affected packages is below - @toptal/picasso-tailwind @toptal/picasso-charts @toptal/picasso-shared @toptal/picasso-provider @toptal/picasso-select @toptal/picasso-quote @toptal/picasso-forms @xene/core @toptal/picasso-utils @toptal/picasso-typograph All the Node.js libraries were embedded with identical payloads in their package.json files, attracting a total of about 5,000 downloads before they were removed from the repository. The nefarious code has been found to specifically target the preinstall and p...

Threat actors are actively incorporating public cloud services from Amazon and Microsoft into their malicious campaigns to deliver commodity remote access trojans (RATs) such as  Nanocore ,  Netwire , and  AsyncRAT  to siphon sensitive information from compromised systems. The spear-phishing attacks, which commenced in October 2021, have primarily targeted entities located in the U.S., Canada, Italy, and Singapore, researchers from Cisco Talos said in a report shared with The Hacker News. Using existing legitimate infrastructure to facilitate intrusions is increasingly becoming part of an attacker's playbook as it obviates the need to host their own servers, not to mention be used as a cloaking mechanism to evade detection by security solutions. In recent months, collaboration and communication tools like  Discord, Slack, and Telegram  have found a place in many an infection chain to  commandeer and exfiltrate data  from the victim machines....

Last week’s cyber news in 2025 was not about one big incident. It was about many small cracks opening at the same time. Tools people trust every day behave in unexpected ways. Old flaws resurfaced. New ones were used almost immediately. A common theme ran through it all in 2025. Attackers moved faster than fixes. Access meant for work, updates, or support kept getting abused. And damage did not stop when an incident was “over” — it continued to surface months or even years later. This weekly recap brings those stories together in one place. No overload, no noise. Read on to see what shaped the threat landscape in the final stretch of 2025 and what deserves your attention now. ⚡ Threat of the Week MongoDB Vulnerability Comes Under Attack — A newly disclosed security vulnerability in MongoDB has come under active exploitation in the wild, with over 87,000 potentially susceptible instances identified across the world. The vulnerability in question is CVE-2025-14847 (CVSS score: 8.7)...

Hackers aren’t kicking down the door anymore. They just use the same tools we use every day — code packages, cloud accounts, email, chat, phones, and “trusted” partners — and turn them against us. One bad download can leak your keys. One weak vendor can expose many customers at once. One guest invite, one link on a phone, one bug in a common tool, and suddenly your mail, chats, repos, and servers are in play. Every story below is a reminder that your “safe” tools might be the real weak spot. ⚡ Threat of the Week Shai-Hulud Returns with More Aggression — The npm registry was targeted a second time by a self-replicating worm that went by the moniker "Sha1-Hulud: The Second Coming," affecting over 800 packages and 27,000 GitHub repositories. Like in the previous iteration, the main objective was to steal sensitive data like API keys, cloud credentials, and npm and GitHub authentication information, and facilitate deeper supply chain compromise in a worm-like fashion. Th...

Cybersecurity researchers have uncovered a never-before-seen dropper that serves as a conduit to launch next-stage malware with the ultimate goal of infecting Windows systems with information stealers and loaders. "This memory-only dropper decrypts and executes a PowerShell-based downloader," Google-owned Mandiant said . "This PowerShell-based downloader is being tracked as PEAKLIGHT." Some of the malware strains distributed using this technique are Lumma Stealer , Hijack Loader (aka DOILoader, IDAT Loader, or SHADOWLADDER), and CryptBot , all of which are advertised under the malware-as-a-service (SaaS) model. The starting point of the attack chain is a Windows shortcut (LNK) file that's downloaded via drive-by download techniques -- e.g., when users look up a movie on search engines. It's worth pointing out that the LNK files are distributed within ZIP archives that are disguised as pirated movies. The LNK file connects to a content delivery network...

In a world where threats are persistent, the modern CISO’s real job isn't just to secure technology—it's to preserve institutional trust and ensure business continuity. This week, we saw a clear pattern: adversaries are targeting the complex relationships that hold businesses together, from supply chains to strategic partnerships. With new regulations and the rise of AI-driven attacks, the decisions you make now will shape your organization's resilience for years to come. This isn't just a threat roundup; it's the strategic context you need to lead effectively. Here’s your full weekly recap, packed with the intelligence to keep you ahead. ⚡ Threat of the Week New HybridPetya Ransomware Bypasses UEFI Secure Boot — A copycat version of the infamous Petya/NotPetya malware dubbed HybridPetya has been spotted. But no telemetry exists to suggest HybridPetya has been deployed in the wild yet. It also differs in one key respect: It can compromise the secure boot featu...

Security Service Edge (SSE) platforms have become the go-to architecture for securing hybrid work and SaaS access. They promise centralized enforcement, simplified connectivity, and consistent policy control across users and devices. But there's a problem: they stop short of where the most sensitive user activity actually happens—the browser. This isn’t a small omission. It’s a structural limitation. And it’s leaving organizations exposed in the one place they can’t afford to be: the last mile of user interaction. A new report Reevaluating SSEs: A Technical Gap Analysis of Last-Mile Protection analyzing gaps in SSE implementations reveals where current architectures fall short—and why many organizations are reevaluating how they protect user interactions inside the browser. The findings point to a fundamental visibility challenge at the point of user action. SSEs deliver value for what they’re designed to do—enforce network-level policies and route traffic securely between en...

Threat actors are creating fake websites hosting trojanized software installers to trick unsuspecting users into downloading a downloader malware called Fruity with the goal of installing remote trojans tools like Remcos RAT. "Among the software in question are various instruments for fine-tuning CPUs, graphic cards, and BIOS; PC hardware-monitoring tools; and some other apps," cybersecurity vendor Doctor Web  said  in an analysis.  "Such installers are used as a decoy and contain not only the software potential victims are interested in, but also the trojan itself with all its components." The exact initial access vector used in the campaign is unclear but it could potentially range from phishing to drive-by downloads to malicious ads. Users who land on the fake site are prompted to download a ZIP installer package. The installer, besides activating the standard installation process, stealthily drops the Fruity trojan, a Python-based malware that unpacks an MP...

In early December 2025, security researchers exposed a cybercrime campaign that had quietly hijacked popular Chrome and Edge browser extensions on a massive scale. A threat group dubbed ShadyPanda spent seven years playing the long game, publishing or acquiring harmless extensions, letting them run clean for years to build trust and gain millions of installs, then suddenly flipping them into malware via silent updates. In total, about 4.3 million users installed these once-legitimate add-ons, which suddenly went rogue with spyware and backdoor capabilities. This tactic was essentially a browser extension supply-chain attack. The ShadyPanda operators even earned featured and verified badges in the official Chrome Web Store and Microsoft Edge Add-ons site for some extensions, reinforcing user confidence. Because extension updates happen automatically in the background, the attackers were able to push out malicious code without users noticing a thing. Once activated in mid-2024, the...

Ambitious Employees Tout New AI Tools, Ignore Serious SaaS Security Risks Like the  SaaS shadow IT  of the past, AI is placing CISOs and cybersecurity teams in a tough but familiar spot.  Employees are covertly using AI  with little regard for established IT and cybersecurity review procedures. Considering  ChatGPT’s meteoric rise to 100 million users within 60 days of launch , especially with little sales and marketing fanfare, employee-driven demand for AI tools will only escalate.  As new studies show  some workers boost productivity by 40% using generative AI , the pressure for CISOs and their teams to fast-track AI adoption — and turn a blind eye to unsanctioned AI tool usage — is intensifying.  But succumbing to these pressures can introduce serious SaaS data leakage and breach risks, particularly as employees flock to AI tools developed by small businesses, solopreneurs, and indie developers.

A previously undocumented malware downloader has been spotted in the wild in phishing attacks to deploy credential stealers and other malicious payloads. Dubbed " Saint Bot ," the malware is said to have first appeared on the scene in January 2021, with indications that it's under active development. "Saint Bot is a downloader that appeared quite recently, and slowly is getting momentum. It was seen dropping stealers (i.e.  Taurus  Stealer) or further loaders ( example ), yet its design allows [it] to utilize it for distributing any kind of malware," said Aleksandra "Hasherezade" Doniec, a threat intelligence analyst at Malwarebytes . "Furthermore, Saint Bot employs a wide variety of techniques which, although not novel, indicate some level of sophistication considering its relatively new appearance." The infection chain analyzed by the cybersecurity firm begins with a phishing email containing an embedded ZIP file ("bitcoin.zip...

I recently hopped on the  Lookout podcast  to talk about virtual private networks (VPNs) and how they've been extended beyond their original use case of connecting remote laptops to your corporate network. Even in this new world where people are using personal devices and cloud apps, VPN continues to be the go-to solution for remote access and cloud access. After my conversation with Hank Schless, I was inspired to put some additional thoughts about VPN on paper. When most organizations were forced to shift to remote work last year, they needed a quick-fix solution that would enable their remote employees to access work resources securely. For many, this solution came in the form of VPNs. However, VPNs were not designed for the bring your own device (BYOD) and cloud app use cases. While VPNs are able to provide remote access, it may come as a surprise that they fall short when it comes to security. This is because VPNs were built for when only a small portion of your workfo...
