Chinese Hacking Group Breaches Email Systems Used by Key U.S. House Committees: Report

 

A cyber espionage group believed to be based in China has reportedly gained unauthorized access to email accounts used by staff working for influential committees in the U.S. House of Representatives, according to a report by the Financial Times published on Wednesday. The information was shared by sources familiar with the investigation.

The group, known as Salt Typhoon, is said to have infiltrated email systems used by personnel associated with the House China committee, along with aides serving on committees overseeing foreign affairs, intelligence, and armed services. The report did not specify the identities of the staff members affected.

Reuters said it was unable to independently confirm the details of the report. Responding to the allegations, Chinese Embassy spokesperson Liu Pengyu criticized what he described as “unfounded speculation and accusations.” The Federal Bureau of Investigation declined to comment, while the White House and the offices of the four reportedly targeted committees did not immediately respond to media inquiries.

According to one source cited by the Financial Times, it remains uncertain whether the attackers managed to access the personal email accounts of lawmakers themselves. The suspected intrusions were reportedly discovered in December.

Members of Congress and their staff, particularly those involved in overseeing the U.S. military and intelligence apparatus, have historically been frequent targets of cyber surveillance. Over the years, multiple incidents involving hacking or attempted breaches of congressional systems have been reported.

In November, the Senate Sergeant at Arms alerted several congressional offices to a “cyber incident” in which hackers may have accessed communications between the nonpartisan Congressional Budget Office and certain Senate offices. Separately, a 2023 report by the Washington Post revealed that two senior U.S. lawmakers were targeted in a hacking campaign linked to Vietnam.

Salt Typhoon has been a persistent concern for the U.S. intelligence community. The group, which U.S. officials allege is connected to Chinese intelligence services, has been accused of collecting large volumes of data from Americans’ telephone communications and intercepting conversations, including those involving senior U.S. politicians and government officials.

China has repeatedly rejected accusations of involvement in such cyber spying activities. Early last year, the United States imposed sanctions on alleged hacker Yin Kecheng and the cybersecurity firm Sichuan Juxinhe Network Technology, accusing both of playing a role in Salt Typhoon’s operations.

Epstein Files Redaction Failure Exposes Risks of Improper PDF Sanitization

 

The United States Department of Justice recently released a new set of documents related to the Jeffrey Epstein investigation, drawing widespread attention after it emerged that some redacted information could be easily uncovered. On December 22, the department published more than 11,000 documents as part of the latest Epstein files release. Although many of the records contained blacked-out sections, some individuals were able to reveal hidden content using a simple, well-known technique. As a result, information intended to remain confidential became publicly accessible. 

Shortly after the release, political commentator and journalist Brian Krassenstein demonstrated on social media how the redactions could be bypassed. By highlighting the obscured areas in certain PDF files and copying the text into another document, the concealed information became visible. This incident highlighted a common issue with PDF redaction, where text is often visually covered rather than permanently removed from the file. In such cases, the underlying data remains embedded in the document despite appearing hidden.  

Security experts explain that PDF files often contain multiple layers of information. When redaction is performed by placing a black box over text instead of deleting it, the original content can still be extracted. Copying and pasting from these files may expose sensitive details. Specialists at Redactable, a company focused on AI-powered redaction tools, have warned that many users underestimate how complex proper PDF sanitization can be. They emphasize the importance of verifying documents before sharing them publicly to ensure sensitive information has been fully removed. 

The situation has raised concerns because U.S. government agencies have long had guidance on secure document redaction. As early as 2005, the National Security Agency published detailed instructions on how to safely sanitize documents before public release. In 2010, the Department of Homeland Security issued reminders stressing the importance of following these procedures. The apparent failure to apply such guidance to the Epstein files has prompted questions about internal review processes and potential security implications. 

This is not the first time redaction failures have exposed sensitive information. Legal experts and journalists have documented multiple high-profile cases involving court filings, media publications, and federal documents where hidden text was revealed using the same copy-and-paste method. The recurrence of these incidents suggests that improper PDF redaction remains a persistent and unresolved problem. 

Beyond the exposure of sensitive content, cybersecurity researchers have also warned about the risks of downloading Epstein-related documents from unofficial sources. Past investigations found that some distributed files were embedded with malware. Threat actors often exploit high-profile events to spread malicious content disguised as legitimate documents, particularly in trusted formats such as PDFs. Researchers at Zimperium’s zLabs team have reported an increase in PDF-based malware and phishing campaigns. Attackers favor PDFs because they appear credible, are widely used in professional settings, and can bypass some security defenses. 

These malicious files are often designed to mimic trusted organizations and target both desktop and mobile users. Experts advise accessing sensitive documents only from official sources and following proper sanitization practices before publication. Software providers such as Adobe recommend using dedicated redaction tools to permanently remove both visible and hidden data. The Epstein files incident underscores that visual redaction alone is insufficient and that improper handling of PDFs can pose serious security and privacy risks.

Trust Wallet Browser Extension Hacked, $7 Million Stolen


Users of the Binance-owned Trust wallet lost more than $7 million after the release of an updated chrome extension. Changpenng Zhao, company co-founder said that the company will cover the stolen money of all the affected users. Crypto investigator ZachXBT believes hundreds of Trust Wallet users suffered losses due to the extension flaw. 

Trust Wallets in a post on X said, “We’ve identified a security incident affecting Trust Wallet Browser Extension version 2.68 only. Users with Browser Extension 2.68 should disable and upgrade to 2.69.”

CZ has assured that the company is investigating how threat actors were able to compromise the new version. 

Affected users

Mobile-only users and browser extension versions are not impacted. User funds are SAFE,” Zhao wrote in a post on X.

The compromise happened because of a flaw in a version of the Trust Wallet Google Chrome browser extension. 

What to do if you are a victim?

If you suffered the compromise of Browser Extension v2.68, follow these steps on Trust Wallet X site:

  • To safeguard your wallet's security and prevent any problems, do not open the Trust Wallet Browser Extension v2.68 on your desktop computer. 
  • Copy this URL into the address bar of your Chrome browser to open the Chrome Extensions panel: chrome://extensions/?id=egjidjbpglichdcondbcbdnbeeppgdph
  • If the toggle is still "On," change it to "Off" beneath the Trust Wallet. 
  • Select "Developer mode" from the menu in the top right corner. 
  • Click the "Update" button in the upper left corner. 
  • Verify the 2.69 version number. The most recent and safe version is this one. 

Please wait to open the Browser Extension until you have updated to Extension version 2.69. This helps safeguard the security of your wallet and avoids possible problems.

How did the public react?

Social media users expressed their views. One said, “The problem has been going on for several hours,” while another user complained that the company ”must explain what happened and compensate all users affected. Otherwise reputation is tarnished.” A user also asked, “How did the vulnerability in version 2.68 get past testing, and what changes are being made to prevent similar issues?”

NtKiller Tool Boasts AV/EDR Evasion on Dark Web

 

A threat actor dubbed AlphaGhoul has now begun to push NtKiller-a perilous tool-on the dark web forums, claiming it silently kills antivirus software and bypasses endpoint detection and response systems. As a malware loader, this tool targets popular security products such as Microsoft Defender, ESET, Kaspersky, Bitdefender, and Trend Micro. This puts organizations relying on traditional security in great danger. Its announcement consolidates the escalating commercialization of evasion tools in the underground. 

NtKiller has a modular pricing system; the base price is $500, while the inclusion of rootkit capabilities or UAC bypass would be an additional $300 each, demonstrating the refinement of cybercriminal sales. KrakenLabs researchers witnessed early-boot persistence, embedding the tool within a system at an early stage of boot time, which is long before most security monitors have become active. This mechanism complicates the work of security teams for detection and removal. 

Beyond basic process killing, NtKiller boasts HVCI disabling, VBS manipulation, and memory integrity bypasses among other advanced evasion tactics. Anti-debugging and anti-analysis protections thwart forensic examination and create a gap between hype and proven performance. The silent UAC bypass escalates privileges with no user prompts, its menace amplified when combined with rootkits for persistent, surreptitious access. 

While the claims target enterprise EDR in aggressive modes, independent verification is lacking, and caution should be exercised when reviewing true efficacy. Such tools pose a more significant challenge to organizations because they take advantage of timing and stealth over signature-based defenses. That makes behavioral detection necessary in the security stacks to help with mitigating these threats.

Cybersecurity professionals recommend vigilance, layered defense, and active monitoring as a way of mitigating tools such as NtKiller in these increasing dark web threats. As cybercriminals continue to improve evasion techniques, it requires moving the advantage beyond simple reliance on traditional antivirus. This incident has highlighted the need for timely threat intelligence within enterprise security strategies.

Phishing Network Exploits e-Challan System to Target Indian Vehicle Owners


 

India has developed a digital traffic enforcement ecosystem that has become more deeply integrated into everyday life, this means that cybercriminals are increasingly exploiting both the public's faith in government systems to perpetrate large-scale financial fraud on the country's streets. 

An e-Challan fraud scam that has recently been uncovered has revealed a comprehensive network of over 36 online fraud sites designed to impersonate government traffic portals and entice unsuspecting vehicle owners into disclosing sensitive financial information through phishing campaigns. It has emerged through Cyble Research and Intelligence Labs that the operation has demonstrated a strategic shift in cybercrime tactics. 

The operation reflects a move away from the delivery of malware through traditional techniques and towards browser-based deception that heavily relies on social engineering techniques. As a result of the fraudulent portals that closely resemble authentic e-Challan platforms, the fraudulent portals are mainly promoted through SMS messages that are sent to Indian motorists, taking advantage of the urgency and credibility associated with traffic violation notices in order to maximize the level of engagement with victims and financial losses they suffer.

Essentially, the phishing campaign targets vehicle owners by sending them carefully crafted SMS messages claiming they have been issued a traffic challan that has not been paid, but they really need to pay it immediately. The messages are designed to cause anxiety among recipients, often warning them of imminent license suspension, legal action, or escalating penalties if they fail to pay. 

The attackers manage to convince their victims that their links are authentic by instilling urgency and fear. Once the recipient clicks on the embedded link, they will be redirected to a fake website in which they would appear to be the official Regional Transport Office and e-Challan portals. A fake platform is a replica of the government's insignia, with its familiar layout and authoritative language, making it very difficult for users to distinguish it from legitimate services at first glance. 

In order to enhance the illusion of authenticity as well as to lower users’ defenses, visual accuracy plays a crucial role in reinforcing this illusion. The scam is based on presenting fabricated information regarding traffic violations. Victims are presented with challan records displaying relatively modest penalty amounts, usually ranging between $ 500 and $ 600. 

According to researchers, the modest sums of these tickets are deliberately chosen to minimize suspicion and encourage a quick payment. In spite of the fact that the violation data presented does not appear to be linked to any official government database, this data has been created simply to give the operation credibility.

However, the ultimate goal of the operation is not the payment of the penalty, but rather to harvest payment information for financial cards. One of the most prominent red flags identified by Cyble Research and Intelligence Labs is the fact that payment functionality on these fraudulent portals is restricted. 

The fake government platforms, on the other hand, accept only credit and debit cards, as opposed to the genuine government platforms which provide a variety of payment options, such as UPI and net banking. Users are asked for sensitive card information, such as their card numbers, expiration dates, CVV numbers, and names.

Although the portal appeared to accept repeated card submissions, even after a transaction appeared to have failed, there were several instances of the portal continuing to accept repeated card submissions. Upon analyzing this behavior, it appears that the attackers are collecting and transmitting card data to their backend systems regardless of whether a payment has been processed successfully, thus enabling multiple sets of financial credentials to be stolen from a single victim, allowing them to steal multiple sets of credentials from the same victim. 

Furthermore, an analysis of the campaign revealed a structured, multi-stage attack pattern. As part of the initial SMS messages, which are usually deceptive and often short URLs, that mimic official e-Challan branding, and that do not include any personalisation, the messages are easily sent at large numbers and do not require any personalisation to be successful. 

Mobile numbers are more frequently used to deliver messages than short codes, which increases delivery success and reduces immediate suspicions. The infrastructure analysis indicates that the attack has a broader scope and is currently evolving. 

Investigators found several phishing domains that were impersonating Indian services like e-Challan and Parivahan hosted by several attacker-controlled servers. As a result of subtle misspellings and naming variations, some of the domains closely resemble legitimate brands. This pattern implies that the campaign is utilizing rotating, automatically generated domains, an approach that has been widely used in recent years to avoid detection, takedowns, and security blocklists. 

Despite countermeasures, it has continued to grow and thrive. After further investigation into the fraudulent e-Challan portals, it has been found that the fraudulent e-Challan portals were part of a well-coordinated criminal ecosystem. 

Upon first glance, the backend infrastructure of both the phishing attacks appears to be based on the same technical system, and this reuse extends well beyond the usual phishing scams associated with traffic enforcement. 

In addition, this network has been observed hosting attacks impersonating prestigious international brands such as HSBC, DTDC, and Delhivery, and holding deceptive websites that purport to represent government-approved transport platforms such as Parivahan, held by officials of the Indian government. 

According to the research, a professional cybercrime operation with shared resources and standardized tools has been observed by consistently reusing the hosting infrastructure, page templates, and payment processes rather than being an assortment of disconnected or opportunistic fraud attempts. Researchers also discovered deliberate evasion strategies that were designed to extend the life of the campaign by bypassing detection and to prolong its lifespan. 

There have also been instances where domain names have been frequently rotated to evade takedowns and security blocklists. Also, there have been instances when phishing templates were originally written in Spanish, but were later translated automatically for Indian targets based on their translation. 

Through carefully crafted urgency-driven messaging, which pressures users to proceed in spite of visible risk indicators, browser security warnings have been neutralised in several cases. A significant number of the malicious domains linked to the operation are still active, underscoring the persistent nature of the campaign as well as the difficulty of disrupting trust-based digital fraud at scale. 

As digital payments and online civic services become more and more prevalent, experts warn that a lack of financial awareness and monitoring is likely to continue to occur in the future as such scams continue to be successful.

It is possible for individuals and businesses to prevent loss and minimize the risk of losses by maintaining clear financial records, routinely reconciling transactions, and closely tracking digital payment activities. There is a growing perception among the Indian business community that these practices are the frontline defence against sophisticated phishing-driven fraud, often supported by professional bookkeeping and financial oversight services. 

There has been an advisory issued by cybersecurity professionals to motorists over the past few weeks, urging them to be cautious when it comes to dealing with digital communications related to traffic. There is an advisory to citizens against clicking on links received in unsolicited messages claiming unpaid fines. 

They are also advised to verify challan details only on official government portals such as parivahan.gov.in, as well as to avoid payment pages that require card numbers in order to complete transactions. Cybercrime authorities need to be notified about suspicious messages and websites as soon as possible. 

More than 36 fake e-Challan websites have been discovered in the past few months. This is a stark reminder that even routine civic interactions can be exploited by organized cybercriminals when vigilance falls short. 

India's rapidly digitizing public services ecosystem, where convenience and accessibility can inadvertently increase cybercriminal attack surfaces, exemplifies a broader threat to this ecosystem. The scale and sophistication of this campaign underscores a broader challenge. 

With online portals becoming the default interface for civic interaction, experts emphasize that more public awareness should be raised, authentication cues should be clearer, and government agencies, telecom carriers, and financial institutions should work together better to disrupt fraud at its source by increasing public awareness. 

There are several proactive measures that could be taken to combat such scams in the future, such as monitoring domains in real-time, tightening SMS filtering, and adopting verified sender IDs widely among mass consumers. 

The importance of digital hygiene for users remains constant - questioning unexpected payments, checking information through official channels, and observing bank statements for irregularities - for users. 

As part of their preventive measures, financial institutions and payment service providers can also strengthen anomaly detection, and send timely alerts for suspicious card activities as soon as possible. 

As India continues to transition toward a digitally-driven governance system, as a result of the fake e-Challan operation, it should serve as a cautionary example of how everyday digital services can be weaponised at scale, reinforcing the need for vigilance, verification, and shared accountability as Indian governance constantly transforms.

Critical MongoDB Flaw Allows Unauthenticated Memory Data Leaks

 


A critical security flaw in MongoDB could allow unauthenticated attackers to extract sensitive data directly from server memory, prompting urgent patching warnings from security researchers and the database vendor. 

The vulnerability, tracked as CVE-2025-14847, affects MongoDB’s implementation of zlib compression and exposes uninitialized heap memory to remote attackers without requiring login credentials. 

Researchers say the issue significantly lowers the barrier for exploitation and could lead to large scale data leaks if left unaddressed. According to security analyses published this week, the flaw exists in MongoDB’s network message decompression logic. By sending specially crafted network packets, an attacker can trigger MongoDB servers to return fragments of memory that were never intended to be shared. 

This memory may contain sensitive information such as user data, credentials, cryptographic material or internal application secrets. The vulnerability impacts a broad range of MongoDB versions across several major releases. 

Affected versions include MongoDB 8.2.0 through 8.2.2, 8.0.0 through 8.0.16, 7.0.0 through 7.0.27, 6.0.0 through 6.0.26, 5.0.0 through 5.0.31 and 4.4.0 through 4.4.29. Older branches including versions 4.2, 4.0 and 3.6 are also affected and do not have backported fixes. 

MongoDB has released patched versions to address the issue, including 8.2.3, 8.0.17, 7.0.28, 6.0.27, 5.0.32 and 4.4.30. Security teams are being urged to upgrade immediately, particularly for servers exposed to the internet or reachable through internal network movement. 

For organizations unable to patch right away, MongoDB has recommended temporary mitigations. These include disabling zlib compression in the database configuration or switching to alternative compression algorithms such as Snappy or Zstandard. 

Administrators are also advised to close unused ports and restrict network access to MongoDB instances wherever possible. Technical reviews of the fix show that the vulnerability stemmed from incorrect handling of buffer sizes during decompression. 

The original code returned the size of allocated memory rather than the actual length of decompressed data, leading to unintended memory disclosure. 

The patch corrects this behavior by ensuring only valid data lengths are returned. Security researchers warn that while exploiting the flaw to extract large volumes of meaningful data may require repeated requests over time, the risk increases the longer a vulnerable server remains exposed. Any MongoDB deployment handling sensitive or regulated data is considered at elevated risk.
