Authentication Breach CVE202531324 Cybersecurity malware NetWeaver Patch SAP servers VisualComposer Vulnerability Webshell

Over 1,200 SAP Instances Exposed to Critical Vulnerability Exploited in the Wild

 

Security researchers have issued a warning about a severe vulnerability affecting SAP systems, with over 1,200 instances potentially exposed to remote exploitation. This comes after SAP disclosed a critical flaw in the NetWeaver Visual Composer’s Metadata Uploader earlier this week.

The NetWeaver Visual Composer is a development environment designed for building web-based business applications without coding. It is widely used to develop dashboards, forms, and interactive reports. The Metadata Uploader enables developers to import external metadata into the platform, establishing connections with remote data sources such as databases, web services, and other SAP systems.

SAP has identified the vulnerability as CVE-2025-31324, assigning it the highest severity rating of 10 out of 10. The flaw arises due to a lack of authentication in the Metadata Uploader, allowing attackers to upload malicious files without needing authorization.

Cybersecurity company Keeper, known for its password management and digital vault solutions, highlights the growing need for secure authentication frameworks. The platform utilizes zero-knowledge encryption and provides tools such as two-factor authentication, secure storage, dark web monitoring, and breach alerts.

Upon discovering the issue, SAP first released a workaround, followed by a comprehensive patch in late April. The company is now urging all users to implement the fix immediately. Multiple cybersecurity firms — including ReliaQuest, watchTowr, and Onapsis — have observed real-world exploitation of the flaw. According to reports, attackers have been using it to deploy web shells on compromised servers.

SAP, however, stated to BleepingComputer:

"It is not aware of any attacks that impacted customer data or systems."

There is some discrepancy in the actual number of affected systems. While the Shadowserver Foundation identified 427 exposed servers, Onyphe reports as many as 1,284 vulnerable SAP instances, with 474 already compromised.

VPN Server Switching: Benefits and Best Practices for Privacy and Speed

 

A VPN enhances online privacy by encrypting internet traffic and masking IP addresses. However, how often should you switch servers? The answer depends on your goals and usage patterns, as server hopping offers benefits but is not always necessary.

How VPN Servers Work

A VPN server acts as an intermediary between your device and the internet, creating an encrypted tunnel for your data. This ensures that your online activity remains private and your information is protected from hackers, ISPs, and other snoopers. The VPN server assigns a new IP address to mask your location and identity.

When to Switch VPN Servers

Switching servers can sometimes boost privacy in specific situations, such as for users facing surveillance or censorship. For most users, however, keeping the VPN connected to a single server is sufficient to maintain privacy. Regularly switching servers can disrupt your browsing experience without significantly enhancing security.

1. Bypassing Geographic Restrictions

One of the primary reasons for server switching is to bypass geographic restrictions. Many streaming platforms and websites restrict content based on location, but connecting to a server in a different country can help access otherwise unavailable material. This is particularly useful for travelers or those in regions with heavy internet censorship.

2. Specialized Servers for Specific Tasks

Some VPNs offer specialized servers for tasks like streaming, torrenting, or gaming. While these servers are optimized for specific activities, switching back to a general server after completing the task can provide a better overall experience for everyday browsing.

3. Improving Connection Speed and Stability

Server performance can vary based on factors like server load and proximity to your physical location. If a server is overcrowded or located far away, switching to a closer or less busy one can improve connection speed and stability. This is especially helpful for users seeking faster downloads or uninterrupted streaming.

4. Saving Money While Shopping

Server hopping can also help save money when shopping online. Many websites adjust prices based on the user’s location. By connecting to servers in different regions, you may find lower prices on flights, hotels, or products. Experimenting with various locations can help uncover better deals.

5. Resolving Access Issues

Access issues can arise when certain VPN IP addresses are flagged or blacklisted due to misuse by other users. In such cases, switching to a different server can resolve the problem. Some VPNs also offer dedicated IP addresses for an additional fee, reducing the risk of being blocked.

When Not to Switch Servers

Despite these advantages, most users don’t need to switch servers frequently. A consistent connection to a single server already provides privacy and security benefits. Unless you’re trying to bypass geo-restrictions, troubleshoot access issues, or improve connection speed, sticking to one server is generally sufficient.

Conclusion

Ultimately, server hopping is a useful feature for those with specific needs but isn’t essential for everyday VPN use. By understanding how and when to switch servers, you can make the most of your VPN experience while maintaining privacy and performance.

Exploring the Tor Network: A Comprehensive Look at Online Anonymity and Privacy

 

The Tor network, originally developed in the early 2000s by the U.S. Naval Research Laboratory, has been operated since 2006 by the independent non-profit organization, The Tor Project. The project's primary goal is to offer a free method for anonymizing internet traffic. Approximately 85% of The Tor Project’s funding comes from U.S. government entities, while the remaining 15% is sourced from private donations and NGOs.

Tor, which stands for "The Onion Router," functions by routing a user's connection through three randomly selected servers (nodes), layering encryption like the layers of an onion. The destination site only detects the IP address of the final node, called the exit server, masking the user's original address. The system refreshes the connection route every 10 minutes, though the access node remains stable for two to three months.

Data transferred within the Tor network is encrypted until it reaches the exit server. However, users must still encrypt any sensitive information entered on websites, as data exiting the network can be read if it's not further encrypted. To access Tor, users need a specialized browser—like the Tor browser, based on Mozilla Firefox and configured for secure browsing.

With about 6,500 servers currently active worldwide, individuals, companies, and organizations operate these nodes. Any internet user with a DSL connection can set up a Tor node. However, the network's openness can be a vulnerability; if an exit node operator is not vigilant, unencrypted data can be intercepted. Additionally, sophisticated entities, such as intelligence agencies, could potentially track Tor users by analyzing traffic patterns or compromising nodes.

Despite these risks, Tor remains the most secure method of maintaining anonymity online. Around two million people, particularly those in heavily monitored states, use the Tor network daily. The darknet, a collection of hidden websites, also depends on Tor's anonymization for access.

Rival Cybercrime Groups Offer Conflicting Accounts of Casino Attack

 

In the latest development, members of the hacking group Scattered Spider have asserted that they were the initial perpetrators of the MGM network breach last week. 

However, the ransomware gang Alphv, also known as Black Cat, countered this claim with a detailed statement on their dark-web platform, insisting that they were the true culprits.

Alphv's statement, while claiming responsibility, left a crucial question unanswered: whether Scattered Spider was acting as an affiliate of Alphv or an independent group utilizing Alphv-developed ransomware. This conflicting narrative is further muddying an already tumultuous news cycle, marked by speculative discussions on social media.

Definitive confirmation regarding the identity of the MGM attacker remains elusive until either the company or law enforcement authorities release public details about the incident. 

Both Scattered Spider and Alphv represent significant cyber threats in their own right, according to experts. Scattered Spider, believed to be comprised of young adults in the U.S. and the U.K., is notorious for employing social engineering tactics in their attacks. 

Charles Carmakal, CTO at Google Cloud's Mandiant, noted their recent use of Alphv's encryption. Their past exploits include a high-profile attack affecting over 130 organizations, resulting in the theft of more than 10,000 employees' login credentials.

Meanwhile, Alphv, thought to be based in Russia, has earned a reputation for conducting ruthless and widespread attacks. Their tactics have included releasing sensitive images from breast cancer patients' examinations while extorting the Lehigh Valley Health Network earlier this year. Notable victims have also included Western Digital and Sun Pharmaceuticals.

In the realm of ransomware, identities are intentionally obscured to hinder law enforcement's efforts to trace attacks back to their source. It's not uncommon for a major ransomware operator to claim credit for an attack initiated by an affiliate. Additionally, a larger group like Alphv could independently carry out an entire attack internally.

Ultimately, MGM, in conjunction with the FBI and third-party cyber incident response firms, will possess the most reliable information regarding the assailant's identity and the specifics of how the breach occurred.

Vietnamese Public Companies Targeted by SPECTRALVIPER Backdoor

 

Vietnamese public companies are facing an ongoing targeted campaign involving the SPECTRALVIPER backdoor. This backdoor, previously undisclosed and in the x64 variant, offers a range of capabilities such as manipulating files, impersonating tokens, and loading PE files. Elastic Security Labs has identified these attacks as the work of REF2754, a threat actor associated with the Vietnamese APT32 group, also known as Canvas Cyclone, Cobalt Kitty, and OceanLotus.

In the latest attack chain, SysInternals ProcDump utility is utilised to load an unsigned DLL file containing DONUTLOADER, which then loads SPECTRALVIPER and other malware. 

SPECTRALVIPER establishes communication with a server controlled by the threat actor to receive commands and employs obfuscation techniques to evade analysis. Additional malware involved in these attacks includes P8LOADER, capable of launching arbitrary payloads from files or memory, and a PowerShell runner named POWERSEAL, which executes provided PowerShell scripts or commands.

REF2754 exhibits tactical similarities to another group known as REF4322, which has targeted Vietnamese entities using the PHOREAL implant. These connections suggest a high likelihood of state-affiliated threats originating from Vietnam.

Meanwhile, Check Point Research has discovered a cyberespionage campaign targeting Libyan organizations, employing a customized backdoor named Stealth Soldier. This malware possesses advanced surveillance capabilities and is believed to be linked to a threat actor known as "The Eye on the Nile."

In the realm of Linux malware, the BPFDoor has received updates to enhance its stealth capabilities, including stronger encryption and improved reverse shell communications. Notably, the latest version of BPFDoor has not been detected as malicious by any currently available antivirus engines for the platform.

SPECTRALVIPER can be compiled as either an executable or DLL to mimic known binary exports. The malware leverages encrypted communication channels (HTTP and named pipe) with AES encryption and either Diffie-Hellman or RSA1024 key exchange. All samples of SPECTRALVIPER undergo heavy obfuscation using the same obfuscator, with varying levels of hardening, making analysis challenging.

Global Ransomware Attack Targets VMware ESXi Servers



Cybersecurity firms around the world have recently warned of an increase in cyberattacks, particularly those targeting corporate banking clients and computer servers. The Italian National Cybersecurity Agency (ACN) recently reported a global ransomware hacking campaign that targeted VMware ESXi servers, urging organisations to take action to protect their systems.

In addition, Italian cybersecurity firm Cleafy researchers Federico Valentini and Alessandro Strino reported an ongoing financial fraud campaign since at least 2019 that leverages a new web-inject toolkit called drIBAN. The main goal of drIBAN fraud operations is to infect Windows workstations inside corporate environments, altering legitimate banking transfers performed by the victims and transferring money to an illegitimate bank account.

These accounts are either controlled by the threat actors or their affiliates, who are then tasked with laundering the stolen funds. The fraudulent transactions are often realized by means of a technique called Automated Transfer System (ATS) that's capable of bypassing anti-fraud systems put in place by banks and initiating unauthorized wire transfers from a victim's own computer.

The operators behind drIBAN have become more adept at avoiding detection and developing effective social engineering strategies, in addition to establishing a foothold for long periods in corporate bank networks. Furthermore, there are indications that the activity cluster overlaps with a 2018 campaign mounted by an actor tracked by Proofpoint as TA554 targeting users in Canada, Italy, and the U.K.

Organisations need to be aware of these threats and take immediate action to protect their systems from cyberattacks. The ACN has reported that dozens of Italian organisations have been likely affected by the global ransomware attack and many more have been warned to take action to avoid being locked out of their systems.

Microsoft Detects Raspberry Robin Worm in Windows Networks

According to Microsoft, a recently detected Windows worm has been discovered on the networks of hundreds of firms from numerous industry sectors. 

The malware, called Raspberry Robin, spreads via infected USB devices and was discovered by Red Canary intelligence experts in September 2021.] In early November, cybersecurity company Sekoia detected it using QNAP NAS devices as command and control servers (C2) servers, while Microsoft stated it discovered harmful artefacts tied to this worm produced in 2019. 

Redmond's findings are consistent with those of Red Canary's Detection Engineering team, which discovered this worm on the networks of several clients, including several in the technology and manufacturing industries. Despite the fact that Microsoft saw the malware communicating to Tor network addresses, the threat actors are yet to exploit the access they gained to their victims' networks. 

As already mentioned, Raspberry Robin is spreading to new Windows frameworks by means of contaminated USB drives containing a noxious .LNK document. When the USB gadget is joined and the user taps the link, the worm brings forth a msiexec interaction utilizing cmd.exe to send off a noxious document put away on the contaminated drive. It infects new Windows gadgets, speaks with its order and control servers (C2), and executes noxious payloads utilizing a few genuine Windows utilities: 
  • fodhelper (a trusted binary for managing features in Windows settings),
  • msiexec (command line Windows Installer component),
  • and odbcconf (a tool for configuring ODBC drivers).
"While msiexec.exe downloads and executes legitimate installer packages, adversaries also leverage it to deliver malware," Red Canary researchers explained. "Raspberry Robin uses msiexec.exe to attempt external network communication to a malicious domain for C2 purposes."

Security specialists who have seen Raspberry Robin in the wild are yet to link the malware to a threat group and are yet dealing with tracking down its administrators' ultimate objective. In any case, Microsoft has labelled this mission as high-risk, considering that the attackers could download and convey extra malware inside the casualties' organizations and heighten their honours anytime.

Novel ToddyCat APT Attacking Microsoft Exchange Servers

 

ToddyCat APT has been targeting Microsoft Exchange servers in enterprises throughout Asia and Europe since at least December 2020. 

The ToddyCat APT  group boosted its attacks in February 2021 and is looking for unpatched Microsoft Exchange servers with ProxyLogon exploits to launch attacks on. A passive backdoor dubbed Samurai and a new Ninja trojan were identified while following the group's activity. Both types of malware take over compromised devices and migrate laterally throughout networks. 

Some of the organisations infiltrated by the gang in three separate countries were hacked at the same time by other Chinese-backed hackers using the FunnyDream backdoor. High-profile organisations from the government and military sectors are the targeted victims. The group appears to be focused on attaining essential goals that are linked with geopolitical objectives. 

Numerous waves of attacks 

The initial wave of strikes began in December 2020 and ended in February 2021. The group was solely targeting a few government entities in Vietnam and Taiwan at the time. Between February and May 2021, the second round of assaults began targeting organisations in a variety of nations, including Iran, Russia, India, and the United Kingdom. 

The group targeted the same set of nations in the following phase, which lasted through February 2022, as well as communities from Uzbekistan, Kyrgyzstan, and Indonesia. ToddyCat Group has expressed interest in the government and military sectors and is expected to continue operations. 

Organizations should employ threat intelligence services to remain up to date on emerging dangers and defend their networks. Additionally, they should utilise the given IOCs to improve threat detection.

Browser Chrome Cyber Security data security Google IP Address Network PNA Privacy Security servers Upgrade Web browser

Due to Security Reasons, Chrome will Limit Access to Private Networks

 

Google has announced that its Chrome browser will soon ban websites from querying and interacting with devices and servers inside local private networks, due to security concerns and past abuse from malware. 

The transition will occur as a result of the deployment of a new W3C specification known as Private Network Access (PNA), which will be released in the first half of the year. The new PNA specification introduces a feature to the Chrome browser that allows websites to request permission from computers on local networks before creating a connection.

“Chrome will start sending a CORS preflight request ahead of any private network request for a subresource, which asks for explicit permission from the target server. This preflight request will carry a new header, Access-Control-Request-Private-Network: true, and the response to it must carry a corresponding header, Access-Control-Allow-Private-Network: true,” as perEiji Kitamura and Titouan Rigoudy, Google. 

Internet websites will be prohibited from connecting if local hardware such as servers or routers fails to respond. One of the most important security features incorporated into Chrome in recent years is the new PNA specification. 

Cybercriminals have known since the early 2010s that they can utilize browsers as a "proxy" to relay connections to a company's internal network. For example, malicious code on a website could attempt to reach an IP address such as 192.168.0.1, which is the standard address for most router administrative panels and is only reachable from a local network. 

When users visit a fraudulent site like this, their browser can issue an automatic request to their network without their permission, transmitting malicious code that can evade router authentication and change router settings. 

These types of attacks aren't simply theoretical; they've happened previously, as evidenced by the examples provided here and here. Other local systems, such as internal servers, domain controllers, firewalls, or even locally-hosted apps (through the http://localhost domain or other locally-defined domains), could be targeted by variations of these internet-to-local network attacks. Google aims to prevent such automated attacks by incorporating the PNA specification into Chrome and its permission negotiation system. 

According to Google, PNA was included in Chrome 96, which was published in November 2021, but complete support will be available in two parts this year, with Chrome 98 (early March) and Chrome 101 (late May).

Lake County government shuts down servers after ransomware attack

After the massive cyberattack in Texas, officials from Lake County, Illinois revealed on Friday, August 23 that the county has been hit by a cyberattack that forced the shutdown of email service and several internal applications.

The officials also mentioned that the breach came in the form of ransomware, which is a type of malware that prevents users from accessing their system or personal files and demands a ransom payment in order to regain access.

Mark Pearman, director of county's information technology office said that on Thursday, August 22, the IT staff was installing cybersecurity software on 3,000 individual employee laptops and working on the process to remove the ransomware malware from 40 county servers.

The ransomware attack was first noticed by systems administrators on Thursday and to prevent it the IT staff started taking encrypted and unencrypted servers off the network.

However, the official clarified that there was no evidence of data theft from county servers and restoring the systems will take the entire week and more information about the attack will be known by Monday, August 26.

As reported, the IT department is working with the county's cybersecurity contractor, Crowdstrike to conduct a damage assessment. This process includes scanning of all the servers, almost 3,000 computers to determine those infected by the ransomware.

Almost a month ago, LaPorte County, Indiana also suffered a similar breach and the authorities paid a ransom of $132,000 worth of Bitcoins to the hackers to restore the access to affected systems.

Another ransomware hit 22 Texas town governments and recently Louisiana was also forced to declare a state of emergency after some of its school districts' networks were hacked. Now, Texas' 22 town government has become the victim of ransomware.

After all these events, National Guard Chief Gen Joseph Lengyel called the events a "cyber storm." He also mentioned that these multi-state cyber attack reiterates the need for more standardized policies and training for cyber units across the force.

Amazon Amazon cloud Card Skimming Card Skimming Malware cloud storage servers

More than 17,000 Domains Affected with Code which Steals Card Data



Cybercriminals running Magecart operations have added payment card skimming code to more than 17,000 domains with JavaScript files in misconfigured Amazon S3 buckets.

Cybercriminals exploited the lack of access control in Amazon's cloud storage services and affected over 17,000 domains via automated attacks which reconstructed JavaScript code randomly, without monitoring if the code could load a payment page.

The exploit came as a part of Megacart operations, originated in the month of April; attackers injected payment card skimming code to a high number of domains with JavaScript files in poorly configured Amazon S3 buckets which granted writing permissions to the person finding them.

According to the security researchers at RiskIQ, the discovery of these S3 buckets had been automated by the authors of the campaign.

Referencing from the findings made by Yonathan Klijnsma, RiskIQ's head of threat research, "Once the attackers find a misconfigured bucket, they scan it for any JavaScript file (ending in .js). They then download these JavaScript files, append their skimming code to the bottom, and overwrite the script on the bucket."

"Even if your bucket has information that anyone can access, it does not mean everyone should be able to modify the content," he added.

The fact that a large number of websites employing Amazon's cloud storage services fell short in fortifying access to the corresponding assets played a major role for Magecart campaign in realizing its malicious objectives.
