Jamey Heary: Cisco Security Expert: Largest Coordinated ATM Rip-off Ever Nets $9+ Million in 30 Minutes With only 100 compromised ATM cards thieves were able to grab $9 million bucks from the banking system in a new style of attack. Law enforcement sources told Fox 5 it's one of the most frightening well-coordinated heists they've ever seen. "We've seen similar attempts to defraud a bank through ATM machines but not, not anywhere near the scale we have here," FBI Agent Ross Rice told Fox 5. "We've never seen one this well coordinated," the FBI said. Wendell Odom's Cisco Cert Zone: OSPF Puzzle IV: LSA Discussion with Sample CCNP OSPF Questions and Polls Even if you work in an OSPF shop, most people don't look OSPF database every day. Most people don't think about the cost of OSPF routes by thinking about what LSAs the SPF algorithm examines to find the cost of each route. What do people do? They design OSPF, configure it, and it generally works without a lot of attention. Larry Chaffin: Putting the realism into your network:Intel's $7 billion 'Made in the USA' investment, yes USA, not India, China or Malaysia This is what we need in technology, a company who gets it and brings jobs and projects back to the USA. In my last artcle I wrote that we needed to do this more and people dont seem to get it. Well Intel did and we need more tech companies to follow suite and bring jobs back to the USA. I think we are all tired of supporting India, China and Malaysia with jobs and outsourcing. Dennis Hartmann on Cisco Unified Communications: Cisco QoS - Low Latency Queuing Class based weighted fair queuing (CB-WFQ) was initially released without the support of a priority queuing (PQ) system. Although real-time voice and video applications could receive bandwidth reservations in the CB-WFQ system, the system could not guarantee the delay and jitter (delay variation) requirements of real-time, interactive voice and video conversations. To address this need, Cisco soon unveiled a new system called low latency queuing (LLQ) that used the same modular QoC CLI (MQC) approach as CB-WFQ. Cisco documentation sometimes refers to LLQ as the following formula: PQ + CB-WFQ. Jimmy Ray Purser: Networking geek to geek: 9 Cool Geek Tips I Just Can't Function Without There are more list out there today then Sushi bars in California. Things like Top 10 Best Hacking Tools or Top 10 Ways to take down Super Mutants in Fallout 3. I have wrote many of these type of list myself and certainly have read even more. In the world of networking, many times the answer to a problem is, "It Depends" For me, list help shorten that, dreaded it depends answer. And truthfully, if I can use a obscure tip to solve a problem, my alpha geek score goes up +24. When I sat down to write this blog, I thought I would write about tips I use so often, that they are stored in NVRAM and called from the buffer easily. This is not a list based upon a weighted value but just stuff I have picked up along the way to make my IT life easier and increase my fishing time. VoIP Security with Patrick Park: Call Flooding Attack As part of VoIP threat series, I'd like to introduce "Call Flooding" which is the typical VoIP attack against availability (refer to previous blog "VoIP Threat Taxonomy" to know the category). Typically, An attacker floods valid or invalid heavy traffic (signals or media) to a target system (for example, VoIP server, client, and underlying infrastructure), and drops the performance significantly or breaks down the system.
