‘Found a nasty bug in my (Cisco) ASA this morning’

The above headline on a post to Reddit piqued my interest this afternoon because it was in that site’s section devoted to system administration and those people know a bug when they encounter one.The Redditor elaborates: “I found a bug in my ASA today. Eth 0/2 was totally unusable and seemed ‘blocked.’ These Cisco bugs are really getting out of hand. I'm just glad I didn't open this port up to the web.”Scare quotes around blocked? Gratuitous mention of the web. I smelled a ruse before even opening the first of three pictures.No. 1, labeled “checking layer 1:”To read this article in full or to leave a comment, please click here

IDG Contributor Network: What does the future hold for the IT services industry?

It would probably be an understatement to say the IT services industry is spooked by the recent financial results reported by major IT services providers. Both the top and the bottom lines have been under pressure. The medium-term future, and even the shorter term, have become unpredictable. Results are inconsistent, and companies have softened their guidance on future growth rates.At the same time, tech spend around the world is increasing. At the NASSCOM Product Conclave in Bangalore a couple of months ago, I was struck by the buoyancy of the start-up market. India alone is home to more than 5,000 start-ups, and this number is slated to more than double by 2020. There is no doubt the tech love affair will continue to heat up as new innovations continue to spring from both unlikely garages and sophisticated computer labs alike.To read this article in full or to leave a comment, please click here

BGP Flowspec Indirection

While Flowspec has been around for a while (RFC5575 was published in 1999), deployment across AS boundaries has been somewhat slow. The primary concerns in deploying flowspec are the ability to shoot oneself in the foot, particularly as poening Flowspec to customers can also open an entirely new, and not well understood, attack surface, and the simple cost of filtering packets. In theory, ASICs can filter packets based on a variety of parameters cheaply. Theory doesn’t always easily translate to practice, however.

Regardless, recent work in Flowspec is quite interesting; particularly the ability to redirect flows, rather than simply filtering them. Of course, the original RFCs did allow for the redirection of flows into a VRF on the local router, but this leaves a good bit to be desired. To make such a system work, you must actually have a VRF into which to redirect traffic; for one-off situations, such as directing attack traffic to a honey pot, building the VRF and populating it can be more work than capturing the traffic is worth. A newer draft, draft-ietf-idr-flowspec-path-redirect, aims to resolve this.

Before getting to the draft specifics, however, it is useful to review the basic concept of Continue reading

Professionally designed ransomware Spora might be the next big thing

Security researchers have found a new ransomware program dubbed Spora that can perform strong offline file encryption and brings several innovations to the ransom payment model.The malware has targeted Russian-speaking users so far, but its authors have also created an English version of their decryption portal, suggesting they will likely expand their attacks to other countries soon.Spora stands out because it can encrypt files without having to contact a command-and-control (CnC) server and does so in a way still allows for every victim to have a unique decryption key.Traditional ransomware programs generate an AES (Advanced Encryption Standard) key for every encrypted file and then encrypts these keys with an RSA public key generated by a CnC server.To read this article in full or to leave a comment, please click here

Your Windows 10 PC may soon lock itself when you walk away

Windows 10 Insider previews are sometimes just full of surprises. An unmentioned feature in Build 15002 was recently uncovered by Windows Central that appears to be a complementary feature to Windows Hello, the biometric login system that automatically unlocks your PC when you sit in front of it.Dubbed Dynamic Lock, this newly discovered feature is designed to automatically lock down your computer when Windows detects that you’re away. It’s not clear if the feature is working yet and Microsoft has yet to discuss it publicly. For that reason it’s unknown what Dynamic Lock actually does. Though Windows Central says Microsoft’s internal name for the feature is “Windows Goodbye,” which indeed suggests a close relationship with Windows Hello.To read this article in full or to leave a comment, please click here

Trump: It was probably Russia that hacked the DNC, Clinton campaign

Russia was likely behind the hacks of the Democratic National Committee and Hillary Clinton's presidential campaign, U.S. President-elect Donald Trump has finally acknowledged. In his first news conference in about six months, Trump also said Wednesday that cybersecurity will be a top priority for his administration. He wants proposals on new hacking defenses within 90 days. "We get hacked by everybody," he said. Trump's new found belief that Russia was responsible for cyberattacks during the presidential campaign comes after months of doubting U.S. intelligence reports that blamed Russia. But Trump also suggested U.S. intelligence may have leaked a 35-page dossier that accuses his campaign of working with Russian intelligence.To read this article in full or to leave a comment, please click here

Worth Reading: The FTC’s IoT challenge

One of the biggest cybersecurity stories of 2016 was the surge in online attacks caused by poorly-secured “Internet of Things” (IoT) devices such as Internet routers, security cameras, digital video recorders (DVRs) and smart appliances. Many readers here have commented with ideas about how to counter vulnerabilities caused by out-of-date software in IoT devices, so why not pitch your idea for money? Who knows, you could win up to $25,000 in a new contest put on by the U.S. Federal Trade Commission (FTC). —Krebs on Security
