Cyber Threat

Shai-Hulud NPM Supply Chain Attack Expands to 470+ Packages 

Summary: A large-scale malicious campaign, nicknamed the Shai-Hulud attack, has impacted the npm ecosystem with over 500 trojanized packages, including those packages maintained by CrowdStrike. The attack originated from a sophisticated phishing campaign that exploited the fundamental trust relationships within the npm ecosystem. 

The JavaScript ecosystem is under a massive threat following a major supply chain attack. Hence, millions of crypto users and developers are now at risk. With more than a billion of these packages downloaded already, thousands of blockchain wallets and applications could be suffer varying exploits.

  • Malicious NPM updates spread malware that steals and replaces crypto addresses.
  • Developers encouraged developer to cease on-chain operation and inspect HD wallets thoroughly.

The attackers injected malicious scripts that

  • Run secret-scanning tools on developer systems, 
  • Steal GitHub, npm and cloud credentials, 
  • Insert persistent GitHub Actions workflows for long-term access, and 
  • Exfiltrate sensitive data to attacker-controlled endpoints. 

This attack is ongoing and all users of npm packages should take immediate steps to secure tokens, audit their environments and verify package integrity. 

Issue Details 

Initial discovery on September 14, 2025, when suspicious versions of @ctrl/tinycolor and ~40 other packages were flagged. By September 16, the attack had spread to include CrowdStrike-namespaced packages and dozens from @ctrl, @nativescript-community, rxnt, @operato, and others. 

Malware behavior 

  • Downloads and runs TruffleHog, a legitimate secret scanner. 
  • Harvests secrets from local machines and CI/CD agents (npm tokens, GitHub PATs, AWS/GCP cloud keys). 
  • Writes malicious workflows into .github/workflows (shai-hulud-workflow.yml). 
  • Continuously exfiltrates findings to a fixed webhook endpoint or pushes them into new GitHub repos under the victim’s account. 

Attack Flow 

Here are some popular packages with affected versions 

Package Version 
@ctrl/ngx-codemirror 7.0.1, 7.0.2 
@ctrl/tinycolor 4.1.1, 4.1.2

Recommendations

Organizations and developers using npm should take immediate actions: 

  1. Uninstall or downgrade 
    Pin dependencies to known-safe versions until patched releases are confirmed. 
  1. Rotate credentials 
    Immediately revoke and reissue: 
  • npm access tokens 
  • GitHub personal access tokens / org tokens 
  • Cloud credentials (AWS, GCP, Azure) 
  1. Audit systems 
  • Inspect developer machines and CI/CD build agents for signs of the malicious bundle.js. 
  • Check .github/workflows for unauthorized files named “shai-hulud-*”. 
  • Review repositories for suspicious commits or new repos labeled “Shai-Hulud Migration”. 
  1. Monitor and log 
  • Search event logs for unusual npm publish activity. 
  • Investigate GitHub Actions runs designed to exfiltrate secrets. 
  1. Harden pipelines 
  • Pin package versions and use integrity checks (e.g.- lockfiles, checksums). 
  • Limit exposure of sensitive tokens in build environments. 
  • Rotate all build-related secrets regularly. 

 
Conclusion 
This incident is significant compromises in the npm ecosystem, impacting hundreds of widely used packages across various namespaces.

The attackers’ tactics such as credential theft, manipulation of GitHub workflows, and widespread package propagation, highlighting the growing sophistication of modern supply chain attacks.

Developers and organizations are strongly advised to take immediate action by removing affected package versions, rotating any exposed secrets, auditing their build environments and strengthening CI/CD security. Continuous monitoring and rapid response are essential to reducing risk and maintaining trust in open-source software. 

The attack’s browser API-level operation revealed critical blind spots in enterprise security monitoring, particularly for organizations handling cryptocurrency transactions.

Kaspersky reveals SharePoint ToolShell vulnerabilities stem from incomplete 2020 fix.

Kaspersky’s Global Research and Analysis Team (GReAT) discovered that the recently exploited ToolShell vulnerabilities in Microsoft SharePoint originate from an incomplete fix for CVE-2020-1147, first reported in 2020.

IntruceptLabs have published the security advisory https://intruceptlabs.com/2025/07/toolshell-zero-day-exploits-in-microsoft-sharepoint-enable-full-remote-takeover/ on 21st July 2025.

The SharePoint vulnerabilities have emerged as a major cybersecurity threat this year amid active exploitation. Kaspersky Security Network showed exploitation attempts worldwide, including in Egypt, Jordan, Russia, Vietnam and Zambia.

The attacks target organizations across government, finance, manufacturing, forestry and agriculture sectors. 

Two newly discovered zero-day vulnerabilities (CVE-2025-53770 and CVE-2025-53771) in Microsoft SharePoint Server are being actively exploited in the wild.

There is currently no patch available to plug this security hole, but Microsoft says that customers running on-premises SharePoint Servers can stop attackers from exploiting the vulnerability by configuring Antimalware Scan Interface (AMSI) integration in SharePoint and deploying Defender AV on all SharePoint servers.

Share point Vulnerabilities a major cyber threat

The SharePoint vulnerabilities have emerged as a major cybersecurity threat this year amid
active exploitation. Kaspersky Security Network showed exploitation attempts worldwide,
including in Egypt, Jordan, Russia, Vietnam and Zambia.

The attacks target organizations across government, finance, manufacturing, forestry and agriculture sectors. Kaspersky solutions proactively detected and blocked ToolShell attacks before the vulnerabilities were publicly disclosed.

Kaspersky GReAT researchers analyzed the published ToolShell exploit and found it alarmingly similar to the 2020 CVE-2020-1147 exploit.

This suggests that the CVE-2025- 53770 patch is, in fact, an effective fix for the vulnerability that CVE-2020-1147 attempted to address five years ago.
The connection to CVE-2020-1147 became evident following the discovery of CVE-2025- 49704 and CVE-2025-49706, patched on July 8. However, these fixes could be bypassed by adding a single forward slash to the exploit payload.

Once Microsoft learned of active exploitation of these vulnerabilities, they responded with comprehensive patches that addressed potential bypass methods, designating the vulnerabilities as CVE-2025-53770 and CVE-2025-53771.

The surge in attacks against SharePoint servers worldwide occurred during the window between initial exploitation and full patch deployment. Despite patches now being available for the ToolShell vulnerabilities, Kaspersky expects attackers will continue exploiting this chain for years to come.

“Many high-profile vulnerabilities remain actively exploited years after discovery —
ProxyLogon, PrintNightmare and EternalBlue still compromise unpatched systems today.

We expect ToolShell to follow the same pattern: its ease of exploitation means the public exploit
will soon appear in popular penetration testing tools, ensuring prolonged use by attackers,”
said Boris Larin, principal security researcher at Kaspersky GReAT.

Iran & Israel war shaping cyber warfare; Hacktivism a tool used widely for Proxy Warfare

Iran & Israel war shaping cyber warfare; Hacktivism a tool used widely for Proxy Warfare

The latest in geo -politics is Israeli air strikes on Iran that triggered Hacktivist to attack and they chose social media platform to announce their activities ‘The Telegram platform’. Now cyber war fare is taking a different path and has no borders and enemy is not visible. One shot of attack is enough to bring down and cripple and entire system starting from banking systems to power grids.

Hacktivist group often uses Telegram as first approach to share about their cyber-attacks and victims list. The hacktivist group DieNet claimed that they will attack Israeli radio stations and   announced it in Telegram.

Israeli cyber officials expect more spear-phishing, malware and similar patterns of attack attempts in the days ahead. Iran is currently engaged in a cyber-conflict with Israel and uses major two hacktivist groups that helps conduct destructive cyber-attacks, linked to Iran’s Ministry of Intelligence and Security (MOIS).

According to NSFOCUS Fuying Lab, hacker groups targeting Israel and Iran have been active since 2025. Up to now, there are about 170 hacker groups attacking Israel, with about 1,345 cyber attacks on Israel, including about 447 cyber attacks launched against Israel after the conflict broke out. (The Hacktivist Cyber Attacks in the Iran-Israel Conflict – Security Boulevard)

In the past Russia has used “hacktivism” as a tool for proxy warfare for various forms of cyber activities to create fear and uncertainty on their opponent.

The Iranian Cyber Units or forces are mostly linked to MOIS and IRGC the hackers group who use fake identities or front groups to hide their state connections.

Surge in Disruptive Cyber Operations

According to Radware, a global cybersecurity provider, Israel has faced an average of 30 DDoS attacks per day since the conflict’s onset. These attacks primarily target government and public institutions (27%), manufacturing (20%), telecommunications (12%), and media platforms (9%).

DDoS operations overload online services, rendering them inaccessible and often accompany website defacements and data leaks to maximise disruption during crises.

The pro-Iranian hacker group’s attacks on Israel peaked on June 16, the day after the Israeli military’s “massive strike” against multiple Iranian weapons production sites, including surface-to-surface missile production sites, detection radar bases and surface-to-air missile launchers in Tehran.

The targets of attack were mainly concentrated on Israeli government and public sector, national defense, aerospace, education and other industries.

The War in disguise-fought with malicious coding

Now along with tanks and war machineries, another kind of war is being simultaneous wagged i.e. cyber warfare. Here it is unconventional warfare no border no clear enemy. Everything is in disguise to create more sensation and install fear. This is being conducted by either by various state sponsored espionage or individual groups who are posing challenge for nation security.

And sometimes this kind of cyber-attack is fatal as malicious code on any application software can damage the system. Imagine doctors not able to open the required files in their system to check patient history on time, due to swarm of malicious code being pushed in their system and is life threatening for the patient as there is a delay to start treatment.

Again malicious code threats are hidden in software and mask their presence to evade detection by traditional security technologies.

Once any encrypted coding being pushed by threat actors inside organizations network, they can enter network and mail, overload with email messages, steal data like passwords and even reformat hard drives.

Hacktivist are now more empowered and Cyber warfare is now fought in disguise to exert influence and destabilize adversaries. Many methods used by Iran in destructive cyber attacks mirror those used by large ransomware groups, such as abusing vulnerabilities in VPN applications to gain entrance. 

Emergence of New Axis in Cyber warfare

Those countries who lack in having a resilient cyber security infrastructure or organizations particularly fragile are soft targets becomes unintended battlegrounds in the global cyber war.

They make the easy victims either via hacking; data theft, cyber extortion and sometimes major cyber-attack that can sabotage their government systems.

If your capability suffers and able to provide effective defense then remaining vulnerable is an option slowly loosing creditability.

Either as a organization or country this growing disparity in cyber defense capacity has emerged as a new axis of global inequality and thriving grounds for threat actors.

The wave of cyber activity in this present state of Iran and Israel war, highlights how modern conflicts extend beyond physical battlegrounds. Attacks on infrastructure highlights the strategic importance of digital resilience.

Iranian state-sponsored hackers, particularly the APT35 group (also known as Charming Kitten), reportedly used AI to enhance their cyberattacks.

According to Check Point, these operations targeted Israeli cybersecurity experts, computer scientists, and tech executives with sophisticated phishing attempts. The attackers used fake messages and emails designed to trick people into sharing sensitive information, along with realistic decoys and fake login pages mimicking Google’s. 

Here are recommendations to secure your networks against cyber-attacks, happening in disguise. How to improve organizational resilience.

  • First have clear visibility across your network as traffic flows, without visibility it is not possible to stop attack. You can’t defend if your enemy is not visible. Once you have visibility, you can see across the threat landscape in your network and gather intelligence.
  • Now with insights one gathers it’s time to turn insights into action and understand the tactics employed by threat actors. These insights are keys to set up proactive defense.
  • Bring Intrucept as a part of your Security team. We are here to assist you as you need a deeper understanding of evolving threats and ways to mitigate them. Our next gen SIEM is a comprehensive solution for Security Information. It gathers information and then interprets, centralizing all security data for organizations.

For visibility Intru360 gives security analysts and SOC managers a clear view across the organization, helping them fully understand the extent and context of an attack.

  • Simply your workflows with Intru360, which automatically handles alerts, allow faster detection of both known and unknown threats.
  • When it is question of cyber security and threats most organizations face, one need’s to have confidence in the threat intelligence one uses
  • Once you are able to identify latest threats and you will not have to purchase, implement and oversee several solutions and even manage a team security analyst, it is easier. You get to save time and reduce complexity while researching for threats.

At the end we can say its not only responsibility for Government to respond or remain alert to cyber attacks and hackers foul play.

The present decade will witness more cyber war that is parallel along side when two nations go at war with each other deploying different AI-driven tools in their attacks. It is high time to stay alert and practice safe cyber security measures at individual level and enterprise level.

Android Malware Crocodilus; Threat for cryptocurrency wallet Users

Crocodilus is a new banking malware that evades detection from Google’s play protect.

The Android malware has been specifically targeting to steal sensitive cryptocurrency wallet credentials through social engineering. Its convincing overlay screen warns users to back up their wallet key within 12 hours or risk losing access says security researchers.

Why threat researchers call this trojan ?

Crocodilus includes all the necessary features of modern banking malware: overlay attacks, keylogging, remote access, and “hidden” remote control capabilities. Also the malware is distributed via a proprietary dropper that bypasses Android 13 (and later) security protections as per researchers of Threat fabric.

Unlike any banking trojan which takes over devices, Crocodilus is similar in pattern and uses tactics to load a fake overlay on top of the real app to intercept the victim’s account credentials. These are targeted mostly for banking or cryptocurrency app users.

Another data theft feature of Crocodilus is a keylogger and the malware monitors all Accessibility events and captures all the elements displayed on the screen, i.e. it is an accessibility Logger.

Intricacies of Crocodilus Malware

The modus operandi of the malware makes it easier to preform task to gains access to accessibility service, to unlock access to screen content, perform navigation gestures, monitor for app launches.

The malware also offers remote access Trojan (RAT) functionality, which enables its operators to tap on the screen, navigate the user interface, perform swipe actions.

The malware is fitted with dedicated RAT command to take a screenshot of the Google Authenticator application and capture one-time password codes used for two-factor authentication account protection.

Android users are advised to avoid downloading APKs from outside Google Play and to ensure that Play Protect is always active on their devices.

Researchers discovered source code of malware revealing debug messages left by the developer(s), reveal Turkish speaking.

The Expanding Threat landscape with evolving Modern Malware’s

The Crocodilus malware designed to go after high valued assets that targets cryptocurrency wallets and Banks. These malware can make the defense line up of banking system weak and researchers advise to adopt a layered security approach that includes thorough device and behavior-based risk analysis on their customers’ devices.

Modern malware has the capability to break the security defenses of organization even if they are protected by cutting edge solutions to defend. As the threat landscape expand so are sophisticated attacks rising.

Modern malware can bypass most security solutions, including email filtering, anti-virus applications, sandboxing, and even IPS/IDS and sometime few file-less malware leaves no footprint on your computer and is executed exclusively in run-time memory.

In this sophisticated war against threat criminals enterprise security requires is taking services for active threat hunting and be diligent in scanning files meant for downloads.

To improve enterprise security the important aspects needs to be covered increase usage of multi-layer defenses. Protecting against modern malware is an ongoing effort, and rarely it is “set and forget.” Utilize multiple layers of security, including anti-virus software, network layer protection, secure web gateways, and other tools for best results.

Keep improving your security posture against modern malware is an ongoing effort and includes multiple layers of security. With anti-virus software, advanced network layer protection, secure web gateways, and other tools the security posture at enterprise level increases.

Remember your best defenses can be in trouble, so continue monitoring, adapt and train employees, while using comprehensive multi-layer approach to security.

Phishing Crusade Targeted approx 12,000 GitHub Repositories; Victims directed to “gitsecurityapp”

A large-scale phishing campaign has targeted nearly 12,000 GitHub repositories with phony security alerts, reported BleepingComputers.

The alerts, opened as issues on the repositories, inform users of unauthorized login attempts and provide links to change their passwords, review active sessions, or set up MFA.

If a user clicks any of these links, they’ll be taken to a GitHub authorization page for an OAuth app that will grant the attacker control of the account.

The campaign is ongoing, though GitHub appears to be responding to the attacks.

Users were directed to all links within the message to a GitHub authorization page for a malicious OAuth application called “gitsecurityapp.” If authorized, the app grants attackers full control over the user’s account and repositories, including the ability to delete repositories, modify workflows, and read or write organization data.

This consistent messaging across all affected repositories aims to create a sense of urgency and panic, prompting developers to take immediate action.

The fraudulent alert directs users to update their passwords, review active sessions, and enable two-factor authentication. However, these links lead to a GitHub authorization page for a malicious OAuth app named “gitsecurityapp.”

Upon authorization, an access token is generated and sent to various web pages hosted on onrender.com, granting the attacker full control.

(Image courtesy: Bleeping Computers)

The attack, which was first detected on March 16, remains active, though GitHub appears to be removing affected repositories.

Pointers Developers to take key inputs from this incident.

Last week, a supply chain attack on the tj-actions/changed-files GitHub Action caused malicious code to write CI/CD secrets to the workflow logs for 23,000 repositories.

If those logs had been public, then the attacker would have been able to steal the secrets.

The tj-actions developers cannot pinpoint exactly how the attackers compromised a GitHub personal access token (PAT) used by a bot to perform malicious code changes as per threat researchers.

Key pointers for User saftey:

  • For users who have mistakenly authorized the malicious OAuth app revoking access to suspicious OAuth apps through GitHub’s settings.
  • Affected users should review their repository workflows, check for unauthorized private gists, and rotate their credentials to prevent further damage.
  • This attack highlights the increasing threat of phishing campaigns targeting GitHub users.
  • As GitHub continues to investigate and respond, developers must remain vigilant and verify any security alerts before taking action.
  • Rotate your credentials and authorization tokens.

 Wiz suggests that potentially impacted projects run this GitHub query to check for references to reviewdog/action-setup@v1 in repositories.

If double-encoded base64 payloads are found in workflow logs, this should be taken as a confirmation their secrets were leaked.

Developers should immediately remove all references to affected actions across branches, delete workflow logs, and rotate any potentially exposed secrets.

7Zip Mark-Of-The-Web Vulnerability

A high severity vulnerability in 7-Zip is exploiting in the wild. This vulnerability, identified as a Mark-of-the-Web (MoTW) bypass, allows attackers to craft a double archive file that, when extracted, bypasses MoTW protections.

OEM7Zip
SeverityHigh
CVSS7.0
CVEsCVE-2025-0411
Exploited in WildYes
Patch/Remediation AvailableYes
Advisory Version1.0

Overview

The vulnerability enables threat actors to create archives containing malicious scripts or executables, which, due to the flaw, will not receive the usual MoTW protection.

This exposes Windows users to potential attacks and has recently been added to the CISA Known Exploited Vulnerabilities Catalog. Furthermore, a Proof of Concept (PoC) for this vulnerability has been publicly released, increasing the risk of exploitation.

7-Zip vulnerability allows attackers to bypass the Mark of the Web (MotW) Windows security feature and was exploited by Russian hackers as a zero-day since September 2024.

Vulnerability NameCVE IDProduct AffectedSeverity
  MOTW Bypass vulnerability  CVE-2025-0411  7zip  High

Technical Summary

This vulnerability bypasses the Mark-of-the-Web (MoTW) feature, a security measure in Windows operating systems that flags files originating from the internet as potentially untrusted. MoTW is typically applied to files like downloaded documents, images, or executable files, which prompts a warning when opened. However, this vulnerability occurs when 7-Zip fails to properly propagate MoTW protections to files inside double-encapsulated archives.

An attacker can craft an archive containing another archive (a “double archive”), and 7-Zip did not properly propagate MoTW protections to the content to the inner archive.

This flaw allows any malicious content in the inner archive to be executed without triggering any security warnings. Consequently, this exposes Windows users to the risk of remote code execution and other malicious activities.

CVE IDSystem AffectedVulnerability DetailsImpact
CVE-2025-04117Zip Prior to v24.09    This flaw allows attackers to execute arbitrary code through double-encapsulated archives that bypass MoTW protections.Arbitrary remote code injection, potential system compromise

Remediation:

Update 7zip to v24.09 or the latest version. Installing the latest version will ensure that vulnerability is addressed, protecting systems from potential exploitation.

Generic Recommendations

  • Exercise Caution with File Extraction: Always verify the source before extracting files, especially from unfamiliar or untrusted sources.
  • Enhance User Awareness: Educate users on identifying phishing attempts and avoiding clicks on suspicious links or attachments.
  • Monitor for Anomalies: Continuously monitor systems for signs of exploitation, unusual file extraction behaviors, or unauthorized access attempts.

Conclusion

The MoTW bypass vulnerability in 7-Zip represents a serious security concern for Windows users, as it allows attackers to circumvent protective measures and execute malicious code. Updating to the latest version of 7-Zip is the recommended action to ensure systems are protected against this vulnerability.
