Botnet Of Embedded Devices Used To Map Internet

Botnets are mostly linked with spam e-mail campaigns, denial of service attacks and data theft. But global networks of compromised hosts can be used for a variety of ends – not all of them malicious. That was the idea behind “Internet Census 2012,” a stealth project by an unnamed and unknown researcher/hacker to map the entire IPV4 Internet address space using a massive network of compromised devices. The results, published in the form of a research paper, underscore the problem of  unsecured embedded devices, including set top boxes, home routers and critical infrastructure, with the hacker able to locate and compromise these systems, creating a botnet of more than 420,000 nodes. According to a copy of the report, the project grew out of an experiment to locate unprotected devices online using nmap, the open source scanning tool. By compromising each vulnerable host and then enlisting it to scan for other […]

With $Pi Million At Stake, Chrome Withstands Hacker Assault

With $3.14159 million in prize money at stake, Google’s Chrome OS has withstood attempts to hack it in the company’s semi-annual Pwnium contest in Vancouver, a Google spokeswoman told The Security Ledger. In a statement Thursday, Google spokeswoman Jessica Kositz said that the company did not receive any winning entries during the day-long contest, but that the company is evaluating work that may qualify for a partial prize:  a potentially infinite series of Google Wallet transfers in the amounts:  $1 followed by $.50 followed by $.25 followed by $.125 and so on. OK – We made that last part up. Pwnium runs alongside the better known pwn2own contest at CanSecWest. This year, Google is providing funding for both contests. However, in 2012 the company pulled its support for pwn2own, objecting to the lack of a requirement of “responsible disclosure” – in which entrants must disclose the details of their exploits to the […]

EverNote Latest Site Hacked In Coordinated Attack

The online personal and business productivity service Evernote.com said on Saturday that it is the victim of a hack that exposed encrypted user password information, forcing password resets across a broad swath of the service’s 50 million registered users. The Redwood City, California-based firm revealed in a blog post that its internal security team discovered “suspicious activity on the Evernote network” that “appears to have been a coordinated attempt to access secure areas of the Evernote Service.” The company said it sent password reset messages to its users as a “precaution” but didn’t believe that stored information in users’ accounts or payment information had been exposed. The hack is just the latest of a prominent online firm. In recent weeks, Twitter, Facebook, Apple and Microsoft have all reported compromises of their internal networks. Those intrusions were linked to attacks aimed at developers and relied on exploits of previously unknown “zero day” […]

Browser Security Still A Sore Spot For Companies (Podcast)

Podcast: Play in new window | Download (3.9MB) | EmbedSubscribe: Apple Podcasts | Android | Email | Google Podcasts | Stitcher | TuneIn | RSS | https://www.securityledger.com/subscribeClueless “end users” are a common straw man (or woman) in the security industry. They’re blamed for everything from data breaches to malware infections. Accepted wisdom is that companies “get it” when it comes to security – consumers (their employees) don’t. But what if it is the other way around? That’s one tantalizing bit of data you could take away from Qualys’s Browser Check service. The free online vulnerability scanning service has assessed millions of endpoints in its two years of existence. And, by and large, it has found that consumers – not corporate users – are following good security practice by migrating to more modern, and secure web browsers. In  our inaugural Security Ledger Podcast, we sat down with Wolfgang Kandek, the Chief […]

UPDATE: Vulnerability In EAS To Blame For Fake Zombie Apocalypse Warning?

Editor’s Note: Updated to include information on the brand of EAS device that was compromised. – PFR 2/14/2013 OK – the good news is that the dead aren’t rising from their graves and the Zombie Apocalypse hasn’t begun (yet…). The bad news: a phony EAS (Emergency Alerting System) warning about just such a cataclysm earlier this week may have been the result of a hack of what one security researcher says are known vulnerabilities in the hardware and software that is used to distribute emergency broadcasts to the public in the U.S. The warning from Mike Davis, a Principal Research Scientist at the firm IOActive, comes just days after unknown hackers compromised EAS systems at television stations in the U.S. and broadcast a bogus emergency alert claiming that the “dead were rising from their graves” and attacking people. Published reports say that at least four television stations were the victims […]
