In spite of VPNs remaining anonymous online, Trojan horse data packages can trick victims.
Virtual private networks (VPNs) have exploded as a result of the pandemic restrictions, but a report warns that they are particularly vulnerable to attack by analyzing the size of data packets passing through them.
VPNs encrypt IP addresses and connect the user and their provider’s data center. An external packet encapsulates the data packets sent through the VPN tunnel before they are routed.
An external data packet of different sizes is sent to multiple ports in the proposed attack. A lot of them lack the right size and are rejected, but if someone enters the right port, they will be transported there.
To trick the system into thinking that something is coming from the other side of the VPN tunnel, a hacker’s traffic monitor can look at the size of the packet that has passed through it and change its source address accordingly.
Cybercriminals can then send users to fake websites or infect them with malicious information.
It takes physical presence on the right side of the IT network to conduct such an attack, making office workers unsuitable targets.
A child could not conduct these attacks. In some cases, you’ll have to fight a very strong opponent.
It will most likely be used in an authoritarian regime where the state controls the entire infrastructure.
Technical security issues based on privacy, freedom of expression, and human rights.
A Trojan horse attack could work on any VPN.
A beautiful trick is not as important as an important idea. This represents a serious vulnerability in the system.
Virtual Networks (VPNs) have become even more important for millions of users who use those software solutions to escape censorship or protect their traffic from intrusion.
VPNs are not a shield against hacking as some companies believe.
Cisco Systems released a series of stickers to address critical vulnerabilities in a subset of small commercial VPN routers that allow hackers to remotely take over the device.
Approximately 9,000 systems may have been compromised, according to security experts.
Using a special HTTP request, an unsuspecting user can execute arbitrary code or reload the device, resulting in service denial (DoS).
A violation was not reported, however.
Cyber-attacks that do not require access to your IP address cannot be protected by VPNs, including malicious software, phishing, and other cyber attacks.
Unauthorized users can still be exposed if they visit unauthorized websites or attempt to download third-party content.
Most VPN gateways will remain unchanged by the end of 2022, at the height of the trend for home-based work.
The Breakpoint Bad team has reported bugs to several VPN providers but does not expect all VPNs to be updated.
If you want to protect your information from government authorities or anything like that, our recommendation is to avoid using a VPN.
Our Cisco VPN specialist at FieldEngineer can provide guidance and support if you are interested in using the VPN service. She/He can advise you on which connector is most appropriate.
VPN Services: CCNP certification now has specializations from Cisco
Over the past year, Cisco’s network certification line has undergone major changes, and one of those changes is the appearance of Cisco Certified Network Professional (CCNP).
Before Cisco reorganized its certification, 10 Concentrations were associated with Cisco’s Cisco Certified Network Associate (CCNA). Since last year, the CCNA has had no different tracks. There is only one option, and it covers the basics of networking.
There are two concentrations in CCNP, which is the most advanced certification. In the first exam, the basics are covered, and in the second exam, six areas of knowledge are examined:
CCNP Service Provider:
Services focusing on infrastructure knowledge are the most popular choice. The topics covered by concentrations include advanced routing, VPN services, and automation.
Knowledge of infrastructure based on collaborative collaboration is the best choice. Concentration choices in Collaboration include topics such as implementing Cisco collaboration applications and automating Cisco collaboration solutions.
Cisco Certified Downet Expertise:
Cisco focuses on knowledge of software development and design, including APIs, Cisco platforms, application deployment and security, and infrastructure and automation. Concentration topics include data center automation, security automation, DevOps automation, IoT, and cloud computing.

Formerly known as CCNP Routing and Switching, CCNP Enterprise is now a certification. Cisco emphasizes dual-layer (IPv4 and IPv6) architecture, virtualization, infrastructure, network security, and automation. Several concentration choices are available, including network design, SD-WAN, wireless, and automation. (Candidates choose a concentration exam for each professional-level certification.)
CCNP Data Center:
Central Selection specializes in network, compute, storage, automation, and security technologies related to core data center technologies. A concentration choice deals with designing, configuring, implementing, and adjusting Cisco hardware and infrastructure.
Security infrastructure knowledge is the main selection criteria. Topics covered in the CCNP Security Concentration include securing networks with Cisco’s firewall products, activating and configuring Cisco’s ID service machine, and securing email with Cisco’s email security equipment.
