SC Magazine reported today that the Davidson Companies, a Montana-based financial firm disclosed “one of its databases, containing the names and Social Security numbers of 226,000 current and past clients, was illegally accessed ‘by a third party through a sophisticated network intrusion.’” In response the firm “took its public website offline after learning of the intrusion, hired a security consulting firm to investigate the theft and notified the major credit-reporting bureaus after learning about the incident.”

We keep beating the drum at BreachBytes that enterprises need to have a response and recovery plan in place because Breaches are inevitable.

If you have the money ($75K+) and a big data center moving a lot of data, Cisco’s Nexus 7000 series switch offers wickedly fast processing power and a lot of compelling security features. Hopefully this signals an increased interest in network security by the switch vendors.

Running NX-OS version 4.0, the Nexus 7000 switch supports a wide variety of useful security features you’d expect from a high-end switch: 802.1x, RADIUS, MAC-based ACLs for policy enforcement, etc. More important to us at BreachBytes is the native hardware support for NetFlow. I commented Monday on the fact that sFlow is generally more prevalent in switches than NetFlow, however Cisco seems to be challenging this assertion with their OS upgrade and supporting products like the Nexus 7000.

In a previous post I gave a rundown of various software tools for collecting NetFlow data for use in network security incident response. NetFlow is pervasive in routers but another technology, sFlow, is nearly as prevalent in routers and can be collected from switches — an arena that NetFlow does not play in very much as of yet. sFlow is a packet sampling technology and can provide a depth of network visibility — a key component of network forensic and incident response — even beyond what NetFlow can offer. For more information on sFlow check out sflow.org.

There is not as much activity in free software with sFlow compared to NetFlow, however InMon has a great suite of tools that can help enterprises leverage sFlow data from routers and switches. Their sFlow Agent software can sniff packets off a network interface card and convert them into sFlow packets if you do not have a sFlow enabled switch or router but want to test what sFlow can bring to the table.

Yesterday, my BreachBytes co-author Andy wrote about the rise of organized crime in cybersecurity. It is an interesting and alarming trend that we have been discussing for quite some time at Packet Analytics. I have been watching a few developing stories on another trend in the hacker community: hacktivism. The Register reported yesterday on the RIAA website’s recent defacement problems and on the Church of Scientology’s DOS problems. Just this morning Rueters has a blurb about purported cyberattacks aimed at Panama by US hackers angry with the election of Pedro Miguel Gonzalez as the president of the Panamanian legislature (Gonzalez is a murder suspect in the US).

Reading, research and personal experience has led me to believe that modern hackers (I am not including whitehat hackers here — that’s another post) are motivated in one of three ways:

  1. Bragging rights (traditional hackers, script kiddie)
  2. Money (organized crime, identity thieves, scammers)
  3. Ideology (hacktivists, spies)

A quote by Gartner analyst John Pescatore in a recent article in PC World points out a fact that is becoming more and more common and is of grave concern to security experts:

“…government-funded cyber espionage is minimal in comparison to that carried out by criminals motivated to steal information for financial gain.”

Cybercrimes are no longer fashionable pranks by teenage hackers to get their name in the paper. Cybercrime is now being driven by financial gain and in many cases is the result of organized crime. The San Jose Mercury News did an excellent three-part series called “Ghosts in the Browser” which highlighted the rise of organized crime, particularly overseas, in the cyberworld.

What makes this so scary?
