Worth Reading: Breach Presumption

The hipster view of data loss seems to be a shrug of the shoulders these days. As a society, we give up financial data to people that steal it so often that we barely care. We shrug our shoulders, sigh at the inconvenience, set up a new account or two, and move on. Yes, sometimes the damage is more serious than unauthorized charges on our Visa cards, but that’s rare enough to avoid societal outrage. Rather, we’ve simply gotten used to the breaches. via ethan banks

I hope you find something to think about or react to there. I’ve tried to blend some hyperbole with a tablespoon of annoyance and a light dash of technical reality. If you have any specific comments on any of these posts, the right thing to do would be to login to Thwack and comment there, but I’ll take any feedback you want to give, wherever it is.

Ransomware pushers up their game against small businesses

After extorting millions from consumers over the past few years, file-encrypting ransomware creators are increasingly focusing their attention on victims who are more likely to pay up: small and medium-sized businesses.Throughout June and July, over 67 percent of users who clicked on malicious links in CryptoWall-related emails were from the SMB sector, researchers from antivirus vendor Trend Micro found.

Apple devs: Don’t let Apple’s Xcode validation scare you

The Apple App Store has long enjoyed a sterling reputation for screening out malware. But last weekend, the company pulled apps infected with XcodeGhost malware from the Chinese Apple App Store -- infected apps that had apparently been created with a counterfeit version of Apple's Xcode IDE by unsuspecting developers.As a precaution, Apple emailed its developers on Tuesday, recommending that they validate their installed version of Xcode using a simple procedure to ensure it wasn't a hacked version. The email also contained a reminder to "always download Xcode directly from the Mac App Store, or from the Apple Developer website, and leave Gatekeeper enabled on all your systems to protect against tampered software."To read this article in full or to leave a comment, please click here

Privacy group calls for a boycott of tech companies supporting CISA

Privacy advocates are stepping up their lobbying efforts against the controversial cyber threat information sharing bill currently in Congress after several tech giants indicated their support.Activist group Fight for the Future criticized Salesforce for supporting legislation which would "grant blanket immunity for American companies to participate in government mass surveillance programs like PRISM, without meaningfully addressing any of the fundamental cyber security problems we face in the U.S." Accordingly, Fight for the Future said it will abandon the Heroku cloud application platform within the next 90 days and encourages others to follow suit. The letter to Salesforce CEO Marc Benioff was posted on the site YouBetrayedUs.org.To read this article in full or to leave a comment, please click here

An EIGRP Scaling Puzzle

This last week I received an email from a friend asking about scaling. The situation is this: a particular company has well over 100 EIGRP routers on a single L2 service from a provider. Will this scale? What’s more interesting than simply asking about scale, though, is to ask the “why” question — no matter […]

DHCP Details You Didn’t Know

If you’ve been a networking engineer (or a sysadmin) for a few years, you must be pretty familiar with DHCP and might think you know everything there is to know about this venerable protocol. So did I… until I read the article by Chris Marget in which he answers two interesting questions:

  • How does the DHCP server (or relay) send DHCP offer to the client that doesn’t have an IP address (and doesn’t respond to ARP)?
  • How does the DHCP client receive the DHCP responses if it doesn’t have an IP address?

Risky Business #384 — Mark Dowd talks AirDrop pwnage, XCode iOS scandal

We've got a great show for you this week. Mark Dowd drops by to talk about the recent spate of Trojaned iOS apps that made it into Apple's China App Store. We also talk to him about his awesome AirDrop bug. How did it work?
