A security researcher claims to have uncovered a flaw in the Android security model that leaves almost all devices running the mobile operating system vulnerable to attacks and malicious software. Jeff Forristal, the Chief Technology Officer at Bluebox Security posted a description of the flaw on Wednesday. It affects Android devices running any version of the OS released in the past four years, starting with Version 1.6 (codename: “Donut” ) – a population of nearly 900 million devices. Discrepancies in how Android applications are cryptographically signed and then verified by Android allow a malicious attacker to modify the application package file (or APK) code without breaking the cryptographic signature. The implications of the flaw are huge. A malicious application installed on a vulnerable Android device could access any data stored on the device. For applications, such as mobile virtual private network (VPN), an attacker who could alter the application’s code or […]

Future Will Bring More Drones, More Drone Hacks
Unmanned Aerial Vehicles, or UAVs (aka “drones”) are evolving – and fast. Just within the last five years, drones have morphed from stealthy and secretive military gear used for hunting down terrorists in the hills of Afghanistan and Yemen, to widely available consumer technology. The “consumerization” of UAV technology has created a lot of opportunities for Cool! – like this video of a UAV flying over (and almost in to) Niagra Falls. But it has also led to some problems. In March, a UAV “quadrcopter” came within a couple hundred feet of striking an Alitalia flight trying to land at JFK Airport in New York. More concerning: the FAA is set to license tens of thousands of drones for use over the U.S., many by law enforcement or private security firms. That has prompted warnings about a huge breach of privacy for U.S. citizens. But one security researcher warns that […]
The New Normal: Wednesday Is DDoS Day At Citi
How common are crippling denial of service attacks aimed at Western banks? Here’s one sign: Wednesday is unofficially “DDoS day” at Citi, according to a Senior Vice President for Information Security at the financial services powerhouse. Speaking on Wednesday at an event hosted by Perdue University, Mamani Older told an audience at CERIAS 2013 that massive distributed denial of service – or DDoS – attacks have become “business as usual” for Citi, and that those launching the attacks have fallen into a predictable schedule of attacks. Hump day, she said, is Citi’s turn to fend off a torrent of Internet traffic designed to interrupt the bank’s operations and sever its connections to its customers, she said. “We should be getting hit right now,” she said. Older was speaking on a panel on the topic of “security metrics” and “security analysis.” The panel was part of CERIAS 13, an annual information security symposium […]
One Reason Security Is So Hard? Really Bad Reports.
Security is hard. Everyone knows that. The question is: why? After all, our understanding of cyber threats improves with each day. The tools we use to secure our systems have also improved over time – antivirus software, firewalls, application firewalls, intrusion detection, data leak prevention, and so on. And yet, when we look at the data, there’s not much evidence that better understanding and better tools are leading to better security. According to Jonathan Grier, an independent security consultant, the answer to the question ‘Why aren’t we getting better at stopping attacks and protecting data?’ is that we’re not doing a good job of learning from the data we have. In a conversation with The Security Ledger, Grier, the founder of Grier Forensics, said that, despite a wealth of security data, the security industry’s approach to analyzing it is immature. Grier likes working on the cutting edge of computer forensics and application security. […]
Welcoming A New Sponsor: The Trusted Computing Group!
The Security Ledger is a new, online publication that’s serious about reporting on security and “The Internet of Things.” While we’ve had tremendous success in our first six months of operation, any new endeavor involves some risk. That’s why I’m thrilled to have had the backing of some forward-looking sponsors: Qualys and Veracode. And today, I’m happy to add a new name to that list: The Trusted Computing Group (TCG). For those of you who aren’t familiar with TCG, its best known as the group behind the Trusted Platform Module (TPM) secure, cryptographic chip that ships with almost every modern desktop and notebook PC. The TPM assures a hardware-based root of trust on compliant system, allowing TPM-equipped systems to securely generate cryptographic keys that can authenticate each endpont for use in secure, online transactions and communications. But TCG actually does a lot more. As a security beat reporter, for example, I […]
