Cisco Survey: 100% of Fortune 500 Hosting Malware?

If you’re working in IT at a Fortune 500 firm, Cisco Systems has some unwelcome news: you have a malware problem. According to the 2013 Annual Security Report from the networking giant, 100 percent of 30 Fortune 500 firms it surveyed sent traffic to Web sites that host malware. Ninety-six percent of those networks communicated with hijacked servers operated by cyber criminals or other malicious actors and 92 percent transmitted traffic to Web pages without content, which typically host malicious activity. “It was surprising that it was 100 percent, but we know that it’s not if you’re going to be compromised, but when,” said Levi Gundert, a technical lead in Cisco’s Threat Research, Analysis and Communications (TRAC) group in an interview with The Security Ledger. Among the high points (or low points) in Cisco’s Report: Cisco observed the highest number of vulnerabilities and threats on its Intellishield alert service in the 13 years […]

Verizon: New Cloud Encryption Service Will Secure IoT Devices

Identity is one of the biggest challenges facing companies that are deploying products for the “Internet of Things,” as well as traditional enterprises that find IoT technologies of all types knocking at the door. The question, in short, is “how do I know that this device is legitimate, and ties back to an identity that I trust with access to my network resources and data? Of course, identity management has always been an aching problem in the enterprise space. The problem with the IoT is scale – given the sheer size of the IoT (30 billion connected devices by 2020), you can add a few “zeros” onto the number of devices that could, potentially, be seeking access to your network at any time. [Related read: Identity Management’s Next Frontier: The Interstate] It makes sense that, in a distributed environment like that, the cloud may be the best place to address […]

BitSight: A Equifax For Security Risk?

I’ve opined in these pages and elsewhere that one of the big problems in the IT security space is the absence of actionable data. After all, problems like denial of service attacks, network compromises and inadvertent data leaks are all just risks that organizations and individuals must grapple with in our increasingly wired world. True – they’re new kinds of risks, but otherwise they’re not fundamentally different from problems like auto accidents, property crime or illness – things  that we do a good job accounting for. The difference, as I see it, is an absence of accepted and independent means of assessing the relative security posture of any organization. IT security is still so much dark magic: we rely on organizations to tell us about how secure they are. Organizations, in turn, rely on a complex and patchy network of security monitoring and detection tools, then try to read the […]

New Mobile Malware Taps Ad Networks To Spread

It was only a couple weeks back that we wrote about new research from the folks at WhiteHat Security that posited a way for mobile ad networks to be gamed and used to distribute malicious code. Now it looks as if the bad guys were one step ahead, as researchers at Palo Alto Networks reveal new type of malicious Android malware that uses mobile ad networks to infect vulnerable devices. Palo Alto described the new, malicious mobile software, dubbed “Dplug,” in a blog post on Monday. The company said the malware authors appear to be leveraging second tier mobile ad networks, mostly in Russia and the former Soviet Republics), to distribute their wares. The Dplug malware takes advantage of the deep integration between mobile applications and mobile advertising networks to gain a foothold on infected devices, then send out messages to premium SMS services to generate money for the fraudsters, according […]

Spammers Using Yahoo, Google To Whitewash Links

If the gigantic distributed denial of service (DDoS) attacks against the spam blacklisting operation Spamhaus wasn’t proof enough: spammers have trouble steering around blacklists and other reputation-based filters. Even if the language in their message is generic enough to avoid detection, dropping a link to a known, malicious- or compromised domain is plenty to get an entire message dropped. Spammers without a legion of 100,000 bots at their fingertips have to get creative about getting their message into the target’s inbox. Lately, a method that’s drawing attention is to leverage low-security redirection services to whitewash a link to a ‘known-malicious’ or merely suspicious sites. Barracuda Networks said that it has captured spam attacks that are combining a Yahoo based URL shortening service with Google’s free Translate service to whitewash links in spam e-mail messages and evade automated detection. The message, which was sent to a Barracuda “honeypot” system  includes a […]
