The Internet continues to expand, evolve and develop. Born as a technology out of a military requirement, Arpanet, the ubiquitous nature of the Internet has meant that mankind has developed all kinds of uses for this communication medium. I sometimes think what would happen, if one day we woke up and found that the Internet was gone. The Internet has managed to permeate and touch our lives unlike no other technology. We are increasingly becoming more and more reliant on it to satisfy our insatiable urge for knowledge and entertainment. We can now, even watch our favourite television programmes across the Internet and stream our favourite programmes across continents ourselves using technologies, such as the Slingbox.

For this blog, as with most of my articles, I won’t reinvent the wheel, and as always will use existing web related resources, wherever, possible. In today’s blog, I am aiming to:

1. De-mystify web conferencing, webinars, teleconferencing and video conferencing.
2. Provide a list of web conferencing/webinar solutions/teleconferencing/video conferencing for small to medium enterprises (SMEs) and larger businesses.
3. Provide further resources/reviews for informed decision making.
4. Explain the difference between web conferencing/webinars and teleconferencing.
5. Explain the benefits and features of online meeting software.

One of the problems that bloggers like me and indeed the general public/businesses are facing these days is the old adage, big fish, eat small fish. The IT solution arena, faced with global competition and diminishing returns, a desire by the big players to have monopolies etc has led to the IT market undergoing significant reshuffle and consolidation. This has led to a great deal of confusion on who owns who, especially if you are not actively following the IT industry. For the uninitiated and for the benefit of everyone, the Internet infrastructure is already largely managed by Cisco routers. To provide Cisco with competition in this arena and to strengthen its other networking products, last week HP purchased 3Com.

Let’s stick with the theme in the previous paragraph. Within the web conferencing, webinar, teleconferencing and video conferencing solutions, the demarcation of what now signifies a particular solution is becoming blurred as they all seem to be morphing together, so in the not too distant future, what this morphed technology will become and be called, is open to speculation. This thought is further strengthened by the acquisition of WebEx by Cisco in 2007 and the recent offer in October, this year, of video conferencing solution provider, Tandberg ( UPDATE – This offer, incidentally, has been upped again in November). Within the video conferencing arena, telepresence, has been touted as the next killer application, although while gaining some ground within larger corporates, it hasn’t really taken off. That may change with Polycom’s new telepresence solution. Polycom has created a clever alliance with Microsoft by licensing its technology, thereby protecting its position. As Tandberg bites the dust, in this David vs Goliath battle, so far the Goliath’s seem to have the upper hand as these solutions move into the lucrative world of Smartphones.

Best solutions for SMEs

Dimdim is free for up to twenty users as a hosted solution and free for upto 50 users if a business hosts it on its own servers. I was quite impressed with their clever use of YouTube for their tutorial videos. One site that I visited levied some criticism of its features and I was quite pleasantly surprised to view the first comment submitted was by one of their employees informing the reviewer that his criticism had been submitted to the developers for further investigation. I predict that Dimdim is the web conferencing platform to watch for and should very soon be giving the big players a run for their money.

Yugma is my next free solution and is free for up to 20 people as well. Again, Dimdim and Yugma are the rising stars of the web conferencing world and both offer Pro versions for businesses.

For teleconferencing, I haven’t been able to find many solutions (I admit, I was researching web conference solutions in more detail) but having used BT MeetMe in the past, I believe it is available cost effectively for SMEs. Skype, does allow for upto 25 users to have a teleconferencing call across the Internet FREE but be wary of the possible loss of quality on calls. Skype Video conferencing (requires a web camera) and is currently limited to a one to one session.

Best solutions for larger businesses

It is worth reading Gartner’s Magic Quadrant for web conferencing 2009 prior to making any decisions as it is a great in depth report and to view a comparison of the top ten (In their view). For other reviews, please click on the following: Review 1, Review 2, Review 3.

For larger businesses the names that are most recognised are (in no particular order), WebEx MeetMeNow, Microsoft’s Office Live Meeting, Citrix GoToMeeting, Adobe Acrobat Connect Pro, Fuze Meeting, Intercall, iLinc, MegaMeeting, Glance, WiredRed e/pop, Zoho Meeting, Elluminate Live, IBM Lotus Sametime, Unyte Meeting, PGi Netspoke webconferencing, and others.

To end this week’s blog, I can inform everyone of the topic of next week’s blog. Recently, I have been assisting the CIO Executive Council to promote the Council as the UK Liaison Development Director. Next week, I’ll be discussing reasons why UK CIOs should become members of the CIO Executive Council and how the council can assist the CIOs agenda, as this is an organisation managed by CIOs for CIOs.

To become a member/further information, please contact me ahmed@itfindit.com – http://council.cio.com/.

If you would like to attend our next event detailed below, (CIOs only), please send me an email:

Telefonanschlüsse über Voice over IP ( VoIP) können von Betrügern mißbraucht werden, wie die C’t in Heft 24/2009 berichtet. Es können schnell Rechnungen von z.B. knapp 3.800 € entstehen!

Hacker besorgen sich das Paßwort zum Kundencenter durch Ausspähen oder Erraten, analog zum Klau von Zugangsdaten für’s Onlinebanking. Dann reservieren sie weitere Rufnummern zum Vertrag (bei 1&1 sind bis zu zehn Rufnummern pro Vertrag möglich) und rufen über diese teure 0900-Hotlines an. Innerhalb von wenigen Stunden kommt so eine große Summe zusammen. Möglich macht dies VoIP, da das Internettelefon von überall auf der Welt betrieben werden kann. Wenn ein Kunde ausgenommen wurde, dann werden die Zusatznummern wieder im Kundencenter gelöscht. Die Opfer sind dann recht hilflos.

Möglich wird dieser Betrug aus dem Ausland, weil 0900-Anbieter (hier Nummer X aus Torgau) ihre Setvicenummern an Partner weitergeben, die lediglich per Brief validiert werden.

VoIP or Voice over IP stands for Voice over Internet protocol.

In general it means voice travels over the Internet, theoretically that means any Voice that can be heared over the Internet may be called VoIP. But this term is dedicated to telephone calls being delivered via the Internet, rather than  POTS or Plain Old Telephone Service utilizing the Public Switched Network or Public Circuit-Switched Telephone Networks(PTSN).
Using Voice over IP, any computer or telephone connected to the internet with a broadband connection can call another computer or phone at a fraction of usual cost, or absolutely free. In other words VoIP can turn a standard Internet connection into a way to place free phone calls.

VoIP is packet switched, meaning voice signals are compressed into data packets. These packets contain a sender and receivers IP address, in order to route the packets to the correct destination.

For a more detailed explanation how packets are build and how packet routing works, visit:

The Dawn of the Net

In a circuit switched network, no sender and receiver information is send, since the call is delivered over pre-determined lines and routes/switches. A call from A to B travels always the same way in a public switched network, where a VoIP call travels random routes on the Internet, depending on traffic and congestion.

On a public switched network a call can not be completed if one of the lines between two callers is down. If a route on the Internet is down or congested, data packets are delivered using different routes, which can be somewhat random and allow therefore for the call to be completed at all times.

Since a VoIP is travelling over packet switched networks utilized the same lines as the standard computer data packets, there is less demand on building an appropriate infrastructure, since voice and data travel over the same line.

VoIP or IP Telephony works like computers work on LANs or WANs. It also means that VoIP does not necessarily need a dedicated telephone, but will also work having speakers/headset & microphone in addition to a IP Telephony Software on a PC or Laptop.

Just the thought of using one and the same hardware infrastructure and common data packets to place or receive a call, opens up so many additonal opportunities, like CIT or Computer Integrated Telephony. CIT is technology through which a computer application can intercept a call-”data-packet”, extract relevant information, match it up with a back-end database and deliver caller information to a computer screen in real-time with the call being delivered to the person who receives the call. This is just one of many possible scenarios VoIP has opened us up to.

Acquisitions, mergers and bank failures are very common in today’s society. Banks are forced to look at how they are spending and determine ways to improve the bottom line to remain competitive and provide key differentiators to keep its customer base.

Many Banks have deployed Voice over IP and have realized a savings of 35% – 60% savings off their monthly telecom cost.

For Example: If your Bank has 10 Branches and currently spending $700/month for a T1 line with voice a total of $7,000 per month.

Using SIPS technology reduces the need to purchase a local PBX for branch office which could be approximately $5,000 per location for hardware and maintenance costs (Savings of $50,000)

You could implement a voice over IP solution that lower your cost down to $300/Month per location which is a savings of over $48,000 per year almost $150,000 savings over the term of a 3 year contract. This does not include any long distance charges and many times Banks have local long distance charges between branch offices. The above mentioned are hard cost savings not inclusive of soft cost savings with the overall lower cost of ownership such as; hiring or maintaining a full-time telecom manager or utilizing the resources of an IT manager that must wear more than one hat.

Most companies talk about savings but one very integral part of maximizing the features and capabilities of a Voice over IP system is increased revenue opportunities.

• Your bank can manage advanced or special skill sets and give all your location instant access to personnel that may work out of a central location. These key employees are shared amongst all branches in a very efficient manner that gives your clients instant access to them which results in improved customer satisfaction.
• Employees that work at multiple locations can have their calls follow them to each branch, office or mobile telephone number.
• Call recording and call monitoring capabilities for training and customer service enhancement. You can identify problems before they become serious.
• Call tracking to ensure that the right resources are available during peak hours and seasons
• We have a method that can integrate certain mobiles devices in the corporate network which would result in lower packaged minute bundles from the mobile provider and giving employees the ability to roam around and not be tied to their desks.

VoIP converts voices into digital signals that travel over the Internet. However, it has become difficult to perfect these systems and missed connections and interrupted service are a common problem. VoIP allows the calls to be made from a computer, a special phone, or a regular phone. To use VoIP, a broadband, or high speed, connection is required. If the caller is using a regular phone, the connection is converted to a normal telephone connection before it reaches its destination.

IP Telephony

A practical primer and reference guide to the growing world of IP telephony, Internet telephony, and voice-over-IP

by Walter Goralski and Matthew C. Kolon

According to the U.S. Environmental Protection Agency, “energy consumption by servers and data centers in the United States is expected to nearly double in the next five years to more than 100 billion kWh.”

This is the first in a series of blog posts that will be exploring the topic of developing, managing, and sustaining a resource efficient enterprise data center and the related infrastructure around us.  We will be exploring the responsible consumption of resources that make up the IT environment for the enterprise, examining the popular notions of the “Green” data center and going beyond the mainstream in tackling topics that have an important impact on IT related resource consumption.

We have a responsibility to be good stewards of the resources contributing to our consumption of information technology.  As global citizens we are on a collision course that is unsustainable, given the rapid consumption of energy across the planet as underdeveloped countries advance their economies and developed nations continue to grow and increase their use of automation and other energy consuming conveniences.  Our planet’s uses of energy through non-renewable fossil fuels will likely outpace our ability to find new sources if we don’t reduce and improve the efficiency of our consumption first.  In the most recent U.S. Energy Information Administration International Energy Outlook report in 2009, total world consumption of marketed energy is projected to increase by 44 percent from 2006 to 2030.  The largest projected increase in energy demand is for the non-OECD (Organization of Economic Cooperation and Development; developing countries) economies (http://www.eia.doe.gov/oiaf/ieo/world.html).

An unfortunate and vitally important consequence of this energy consumption is our output of Carbon Dioxide emissions.  Scientifically regarded as a contributor to climate change, total CO2 emissions—as calculated with all projected full measures of CO2 emission reduction programs underway or planned—are projected to increase by 17 percent from 2010 to 2020 (http://www.state.gov/g/oes/rls/rpts/car/90324.htm).

We clearly still have our work cut out for us.

According to the U.S. Environmental Protection Agency, “energy consumption by servers and data centers in the United States is expected to nearly double in the next five years to more than 100 billion kWh, costing about $7.4 billion annually”.  Similar energy cost increases are expected in Europe, Asia, and else­where. (http://www.energystar.gov/ia/partners/prod_development/downloads/EPA_Datacenter_Report_Congress_Final1.pdf).

However with data centers, and the other information infrastructure we have in businesses and the homes to support our information and communication needs around the world, it is still a drop in the bucket compared with overall energy consumption.  What we do have is the capability to turn the information technology into solutions for energy savings.

We see this today with smart grid technology applied by the utility companies to manage home energy usage and provide bi-directional communication between the home appliances and the energy company to manage energy usage wisely and efficiently.  Applied to the data center, smart energy technology can be timed with the business cycles to reduce energy consumption on resources that don’t have to run full throttle for supporting a business application that is comparatively idle.

We will explore these ideas and more in upcoming blog posts, as we delve into improving our information to energy ratio; squeezing more information out of the energy necessary to produce it—and, perhaps taken to the extreme, spending less energy on information that has less value.  Now that’s a tricky topic!

Stay tuned for future posts.

Even a few years ago, connecting international offices was a nightmare in terms of complexity and associated cost. The attraction to connect many offices has many advantages. It helps cut the carbon footprint of employees through less travelling, enhances communications security, as files are not required to be kept on the laptop/removable media, it can save telephone costs by using Voice over Internet Protocol (VOIP) technology, allows collaboration of employees globally through Unified Communications (UC) technologies and creates an infrastructure that is scalable according to the requirements of the business.

The technology that is increasingly being utilised to setup this global infrastructure is Multiprotocol Label Switching (MPLS). MPLS utilises both Class of Service (CoS) and Quality of Service (QoS). This means that data is prioritised according to let’s say, video/voice. For our example, if Video/Voice carries a CoS of 7 that would mean that it has a higher priority for transmission to let’s say data files and then the QoS could reflect that further by fine tuning other parameters such as latency etc.

When creating an international communications strategy, it is advisable to identify the requirements very carefully and to choose a global service provision partner that has experience of enabling international communications such as BT, Cable and Wireless and others.

The improvement that most businesses require immediately is to connect their employees remotely to their internal business network for reaching their business documents, presentations and business applications. The way this is achieved is through ensuring that the headquarter (HQ) or business data centre site has a larger capacity link compared to other sites, as this will be the link that will be the most used by all other sites and remote workers. A few years ago, many businesses used to host all their data and business applications at their headquarter sites. Now, increasingly, as businesses are growing and capacity (bandwidth) is becoming cheaper, they either have their own data centres or use Cloud Computing services.

Next, each remote site’s data requirements are mapped out and the required capacity agreed and enabled. In parallel, most remote workers are granted access to the business systems by using secure Virtual Private Network (VPN) connections and associated solutions such as iPass and RSA SecureID .

Once, the global infrastructure is setup, businesses can start to think about moving away from their Private branch exchange (PBX/PABX)’s telephone network and to start utilising VOIP for Internet Protocol Telephony (IPT). It is also worth noting that VOIP is not allowed in many countries as these countries would like their own country’s Public Switched Telephone Network (PSTN) carrier to carry the VOIP voice traffic and thus make money themselves. Many VOIP solutions, get around these by breaking out voice transmissions locally, in country, and if, for example, they have their own international VOIP system, to utilise their own network for the international traffic only.

An immediate transfer to a complete VOIP system is not required by most vendors and is facilitated by the introduction of VOIP gateways that link the legacy PBX to the new VOIP system. That ensures that investment in the current PBX is realised until a transition to the eventual VOIP benefits and system is completed. The largest disadvantage of VOIP systems is their inability to cope with electricity blackouts (Design consideration can overcome this) and tracing emergency VOIP calls (potential solutions currently being offered by vendors). Most VOIP vendors also sell UC solutions as well. This is where the power of the digital communications strategy starts to pay dividends. VOIP, for example, allows the user to have one extension globally. The power of unified communications is that it starts to utilise presence awareness (Where someone actually is/logged in to a computer/device) and starts to present that information to anyone who wants to connect or collaborate with that individual. This allows geographically diverse teams to connect anytime, anywhere globally. This could be via email, instant messaging, web conferencing, voice, SMS, Fax and even through collaborative technologies such as SharePoint. Now, follows an example:

Peter Smith was reluctant to go to the US but sales were down and a major potential client beckoned. Peter logged off his computer and phone system and made his way to Heathrow airport. Once checked in, he decided to make some calls to colleagues. A quick conference on the laptop ensued that meant he was discussing the project with a global team that he could view and discuss the final phases of a project with, across three offices globally. He was now walking to board the plane and quickly transferred his call to his mobile and continued walking. The call had ended and he had an urgent message to leave another colleague. He knew his colleague was in a meeting and would be checking his emails on his laptop frequently, so he left a voicemail (Voicemail would be emailed as text to his colleague). Once at the US office, he logged in to the system and had instant access to all his files and his personal phone extension.

I am intentionally not discussing VOIP or IP technologies in general as I feel that Unified Communications is where businesses should be making an investment. According to Gartner’s 2009 magic quadrant for Unified Communications, Microsoft’s UC solution is considered to be the leader, with Cisco, IBM and Siemen’s communications following closely. It was interesting to see that Avaya is only a strong contender and it is noteworthy to inform everyone that Avaya completed its acquisition of Nortel recently (the quadrant does not reflect the acquisition). There are quite a few VOIP/UC vendors currently and I would suggest that the one’s to watch are Microsoft, Cisco, Mitel and Avaya.

Many people are confused about the differences between SIP Trunking and VOIP. Centrix Networks actually uses SIP Trunking Technology for it’s Business Phone Solution.

VOIP – Voice over IP is a generic term to cover all voice traffic over the internet. Most Voice over IP is using an older protocol. The H323 Standard which is being replaced by the SIP Protocol.

SIP – Which stands for Session Initiation Protocol is a form of Voice over IP using the SIP Signaling protocol. It has many advantages and features over standard VOIP using the H323 protocol such as the ability to have DID(Direct Inward Dialing) without having to use a PRI or PRI card on a PBX.

One large advantage to SIP Trunking is that one PBX and manage phones at multiple locations. It reduces the need to purchase an expensive PBX for branch locations.

SIP Trunking has advanced features and functionality that gives you flexibility and the ability to develop robust applications.

SIP Trunking is becoming that standard and is the future of telecommunications

At last, after a loooong time, i got some time to breathe and the first thing i wanted to do is write post about my FRHACK experience.

FRHACK is an International IT Security conference by Hackers, for Hackers It is organized by Jerome Athias, a well known hacker from france. First edition of FRHACK was held in a small beautiful town Besancon.

As it was my first talk in an International Security Conference, I was amazed to see hackers around the world sharing their ideas and research work. I got chance to meet IT security gurus, hackers  like David Hulton ( A well known crypto guy), Vlatko Kosturjak ( OpenVAS team member), Philippe Oechslin ( Author of Rainbow Tables),Richard Stallman ( Founder of GNU project).

David Hulton, Me and Blake Cornell

And security consultants and Penetration Testers like Andres Raincho ( Author of W3af tool),jon Rose , Blake Cornell ( One of my good friends and share the good name space in VoIP Security) , Nicolas Thill ( With amazing hair and co-author of HostilWRT)

Me, Jon Rose and Andres Riancho

Conference was running in 2 tracks, it was difficult to attend all the talks. I attended some interesting talks including OpenVAS, The good, bad and ugly of crypto where david showed how easy it is to steal passwords from ASTRA VoIP phones, HostileWRT where Nicolas Thill and Philippe Langlois showed how HostileWRT can be used to turn friendly Wireless Access Point into an Autonomous, Curious, Standalone, Malicious & Really Annoying Device.

Me speaking

My talk was on Unified Communication Security with Microsoft Office Communication Server R1/R2 and was scheduled on second day of the conference. The sole purpose of the talk was to educate and create awareness about UC security around MS OCS R1/R2. At the end of the talk, I released a free source security assessment tool for MS OCS – OATv2.0 which stands for OCS Assessment Tool

OATv2.0

Previous release of OAT was result of some of our integration work and hence had some limitations on Authentication and Transportation protocol front. OAT v2.0 introduces new attack vectors against MS OCS server R1/R2 over TLS and NTLM/Kerberose Authentication protocols.

OAT v2.0 was officially presented and released in my talk at FRHACK 01 with demonstrations of attacks and usage in various penetration testing topologies. I am planning to upload OAT v2.0 along with documentation on its official website soon. As there is no tool available for assessing Microsoft OCS servers, i hope OAT will help to improve security posture of OCS deployments.

I am sharing my slides, for those who missed FRHACK.

Hi ho! Thursday’s security news is right here, right now. Let’s go!

Today we’ve got SMT Online editor Brian Sims with his SMT Online Editor’s View – ruminating on the shadowy security words of Shadow Security Minister Baroness Pauline Neville-Jones.

We’ve also got a surprising story coming out of our I4S India channel, where there’s talk that Voice over IP may be banned out of concerns over its security, or lack thereof. What?!?

We’ve also got a round-up of some recent security-centric books; a security manufacturer is acquired; special students benefit from access; and RemGuard talks winter CCTV tips.

Don’t forget to get along to IFSEC India 2009 if you possibly can. You’d be insane to miss out!

Skype. Für all Diejenigen, die bisher von Instant-Messaging oder Voice-Over-IP gar nichts gehört haben oder aber ausschließlich ICQ nutzen ein paar einführende Worte: Skype ist ein relativ kleines Programm, mit dessen Hilfe andere Skype-User via Internetverbindung kostenlos angerufen werden können (auch Videotelefonie und Telefonkonferenzen). Telefonate ins Festnetz sind gebührenpflichtig aber ebenfalls möglich. Zudem können mit Skype Textnachrichten und Dateien verschickt werden. Zusätzliche Tools ermöglichen gemeinsames Spielen und Remote-Desktop-Verbindungen, die sich insbesondere bei Studenten großer Beliebtheit erfreuen (ein Beispiel: mit Hilfe von Skype können Dokumente von mehreren Nutzern zeitgleich bearbeitet werden; zeitaufwendige Treffen können so ersetzt werden). Skype ist dezentral und funktioniert über die Peer-to-Peer-Struktur.

Ich persönlich nutze Skype seit längerer Zeit und gehe davon aus, dass meine Skype-Nutzung weiter zunehmen wird, denn kostengünstiger kann man im Grunde nicht über große Entfernungen zwischen verschiedenen Ländern kommunizieren und telefonieren. Den Vergleich mit ICQ gewinnt Skype für mich aus zwei Gründen: Zum Einen ist (Video-)Telefonie mit Skype ein Kinderspiel, zum Anderen ist das Programm im Vergleich zu ICQ so gut wie werbefrei und im Design deutlich schlanker und eleganter (zumindest die Mac-Version).

Dennoch gibt es zahlreiche Gründe, Skype nicht zu nutzen. Der wohl entscheidende Punkt ist die Tatsache, dass das Programm proprietär ist und der Quellcode nicht offengelegt wird. Damit entsteht ein mächtiges Instrument, denn die steigende Anzahl an Nutzern und der zunehmende Einsatz in mittelständischen Unternehmen bei Unklarheit über Verschlüsselungsmechanismen birgt für den Eigentümer (aktuell ist dies übrigens eBay) enormes Potential und einen möglicherweise einfachen Zugriff auf sensible Informationen. Zudem ist die Abhörsicherheit nach Meinung zahlreicher Experten nicht gegeben.

Ein weiterer Kritikpunkt ist die Beobachtung, dass Skype im Laufe eines Monats bis zu 1 Gigabyte an Daten sendet (im Leerlauf, wenn man selber lediglich online ist ohne aber Nachrichten oder Anrufe zu tätigen). Welche Art von Daten gesendet wird bleibt dabei weitgehend unklar.

Skype kann also zusammenfassend als Blackbox mit vielen nützlichen Funktionen und Tools bezeichnet werden, die allerdings insbesondere bei sensiblen Daten mit Vorsicht anzuwenden ist. Für mich persönlich überwiegen derzeit klar die Vorteile, aber die Nutzung von Skype zur Abwicklung der gesamten internen Unternehmenskommunikation ist für mich fahrlässig und nicht nachvollziehbar

The Problem: You don’t want your number to show up on the caller ID of the phone you are calling. You could block your number, but you know that no one picks when a caller blocks his number.

The Solution: TelTech’s SpoofCard. TelTech offers the technology to mask your caller ID and have show up on the caller ID of the person you are calling any number you want. If the recipient of your call has a name attached to the number you choose to have display, that name attached to the number will show up.

With the power to assume an identity of your choice when call, comes the responsibility to not abuse this power. Use it to have some fun and play harmless pranks on your friends. You can use it to call a client and make it appears as if you are calling from your office so that your personal phone number doesn’t show up.

To make a spoof call, visit today’s site of the day: www.spoofcard.com

VIPER Lab researchers once again kept their promise of delivering exciting and freaky features in the upcoming version of videoJak.

VideoJak rocked Defcon 17 with some thrilling video attack demonstrations which we have seen only in Bond movies.

My earlier post talked about the old version of VideoJak which was used to demonstrate proof of concept (PoC) Video DoS attack against Cisco 7985 IP video phones.

VideoJak is updated with two brand new attacks.

1. Video Replay, where same video stream is repeatedly played on the target video phone of  Cisco Surveillance  camera.
2. Inserts completely random video stream in the ongoing video conversation or live feed from Surveillance  cameras.

Video Replay attack demo showed stealing of water bottle from the chair by replacing the live feed with the still video captured before the attack. While the second video attack demonstration played a short video clip from the movie “The Italian job”, thereby, replacing the live feed from surveillance camera.

We demand video solutions. Video solutions demand security

Here is the video demonstration of both of the above attacks.
