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.

TellYouThePass Ransomware Exploits Recent PHP RCE Vulnerability to Compromise Servers

 

The TellYouThePass ransomware gang has been exploiting the recently patched CVE-2024-4577 remote code execution vulnerability in PHP to deliver webshells and execute their ransomware payload on target systems.

The attacks began on June 8, less than 48 hours after PHP maintainers released security updates, utilizing publicly available exploit code. TellYouThePass is notorious for quickly adopting public exploits for widespread vulnerabilities. In November, they exploited an Apache ActiveMQ RCE, and in December 2021, they used the Log4j exploit to breach companies.

In the latest attacks observed by researchers at cybersecurity company Imperva, TellYouThePass leveraged the critical-severity CVE-2024-4577 bug to execute arbitrary PHP code. They used the Windows mshta.exe binary to run a malicious HTML application (HTA) file. This file contained VBScript with a base64-encoded string that decoded into a binary, loading a .NET variant of the ransomware into the host's memory.

Ransomware Impact and Tactics

Upon execution, the malware sends an HTTP request to a command-and-control (C2) server disguised as a CSS resource request and encrypts files on the infected machine. It then leaves a ransom note, "READ_ME10.html," with instructions for the victim on how to restore their files. User posts on the BleepingComputer forum indicate that TellYouThePass attacks have claimed victims since June 8, demanding 0.1 BTC (around $6,700) for the decryption key. One user reported that the ransomware campaign affected multiple websites hosted on their server.

Vulnerability Details and Response

CVE-2024-4577 is a critical RCE vulnerability that affects all PHP versions since 5.x. It originates from unsafe character encoding conversions on Windows when used in CGI mode. The vulnerability was discovered on May 7 by Devcore's Orange Tsai, who reported it to the PHP team. A fix was released on June 6 with PHP versions 8.3.8, 8.2.20, and 8.1.29.

The following day, WatchTowr Labs released a proof-of-concept (PoC) exploit code for CVE-2024-4577. The Shadowserver Foundation observed exploitation attempts on their honeypots the same day. According to a report from Censys, over 450,000 exposed PHP servers could be vulnerable to the CVE-2024-4577 RCE vulnerability, with most located in the United States and Germany. Wiz, a cloud security startup, estimated that around 34% of these instances might be vulnerable.
