IETF Approves HSTS as Proposed Standard

One of the things that makes attackers dance around their basement lairs is finding unencrypted Web sessions. Sites that don’t give users the option to use HTTPS make life that much easier for attackers trying to hijack users’ Web sessions or eavesdrop on them. The IETF has taken a big step toward making that more difficult, approving the HTTP Strict Transport Security (HSTS) proposal as an Internet-draft.

Hunting Badware

Security often is discussed in super-serious terms, using metaphors and analogies from the military or medical communities to underscore the gravity of the situation. But the truth is, some of this stuff is pretty funny, and the folks at StopBadware.org know this. To explain the way that attackers use compromised Web sites to infect unsuspecting visitors with malware, the group put together this video featuring actual human people dressed as Web sites.


So now it’s the White House’s turn. Having taken a swing at just about every other piece of the U.S. government’s network infrastructure, attackers, reportedly based in China, recently targeted a machine on an unclassified network inside the White House Military Office and were able to compromise it through a spear-phishing attack. The attack has drawn a lot of attention, as stories that include the words “White House” and “attack” do, but the notion that this attack may be the one that finally forces the U.S. to address the threat from foreign attacks is misguided.

The phrase “you’re doing it wrong” is a common refrain in the security community these days as people wander around in various states of disillusionment with the technology and processes that have led to what many perceive as a systemic failure. But that refrain usually is not followed by any useful discussion of what’s going wrong or what can be done about it. To researcher Claudio Guarnieri, one of the major problems is obvious: we’re completely backward in the way we prioritize protection.

The news yesterday that Adobe had been compromised and that the attackers were able to get valid Adobe signatures on a pair of malware utilities is one of the more worrisome and troubling stories in what has become a year of huge hacks and historic change in the security industry. Adobe was forthcoming with many of the details of the attack, but the ones that were omitted are the ones that really make a difference in this instance.

Telvent, the maker of a SCADA product used in a number of critical industries, said that its corporate network has been compromised by attackers and that some of the files used by customers on their own networks were changed. This attack is the latest in what looks to be a series of incidents of varying severity that have occurred at companies involved in either the production or use of SCADA systems in recent months.

Cisco has released nine security advisories for various products, including eight for its ubiquitous IOS operating system. Many of the vulnerabilities fixed in the patch release are denial-of-service flaws and none of them can give an attacker the ability to run code remotely on affected machines.

Google has released Chrome 22, a major new version of its browser that includes a huge number of security fixes, many of them high-priority vulnerabilities. The company also handed out nearly $30,000 in rewards to security researchers, more than half of it to Sergey Glazunov, who discovered two especially severe bugs that the Chrome security team deemed worthy of special rewards.
