Today Wikileaks released a massive new trove of leaks focused on the CIA's IT-based espionage capabilities . Wikileaks has named the document release Vault 7. The trove has just been released this morning, so details remain sketchy, however the included documents appear to contain detailed information related to dozens of malware tools used by the CIA's Center for Cyber Intelligence. Earlier this morning I heard an NPR report claiming that Wikileaks was redacting the source code associated with these hacking tools. I'm not sure if that is correct; I've found a few files with executable scripts included, but none of the scripts I've found so far are essentially malicious (although they were almost certainly used in the development and packaging of malware). I have found indications that Wikileaks redacted exploit files that were ready for as-is distribution. For example, the files I reviewed in the dump appear to be part of an internal wiki. I reviewed a file list...

Four days ago I received an email from Dawid Golunski through the list illustrating one of the more brutal pair of security vulnerabilities I have seen recently. Here's how it works.     The exploit uses a vulnerability within MariaDB, PerconaDB (and/or XtraDB Cluster) and MySQL to, first, gain access to the 'mysql' system user using any mysql user that has CREATE / INSERT / UPDATE permissions. The first part revolves around a race condition when sql generates temporary files as part of the `REPAIR table` command. Then using the mysql system user the second vulnerability grants the attacker root access to the server using a clever hack that takes advantage of mysql_safe's approach to writing to file based error logs. Below I've provided a list of vulnerable server versions. Just about any server using the more recent (unpatched) stable releases of MySQL or MariaDB through CentOS is vulnerable (Percona isn't part of the st...

Some time ago I wrote two blog posts about my discovery about a series of malware-infected files within a torrent being circulated by global whistleblower organization Wikileaks. The torrent file was one of the latest versions of what Wikileaks has named the "Global Intelligence Files" - a large cache of documents obtained from the email spool of a government contractor known as Stratfor. Since my discovery I have made several attempts to contact Wikileaks: @wikileaks sorry to contact here but no other means Ive identified sec issues with most recent torrent here: https://t.co/oeBLtLgDeb — Josh Wieder (@JoshWieder) May 3, 2015 @wikileaks I have some very basic info here http://t.co/cvjY4xWuIr and here: http://t.co/74Xbmxjmy7 can provide more as needed — Josh Wieder (@JoshWieder) May 3, 2015 In addition to Twitter I have attempted to email just about every address I could find on their site (none of them work), as well as attempting to use the chat functi...

Click here for the second post on this topic, which includes more detailed technical information. Hector Monsegur, formerly sabu of Lulzsec, has offered his point of view on this post. Get his opinion by reading my third post on the topic. In my fourth post on this topic, I explain how malware is not limited to the Stratfor leak torrent - curated links throughout the Wikileaks.Org website allow users to download individual infected files . This series of posts is beginning to receive coverage from several newspapers around the world. German speakers should check out the story in Neue Zürcher Zeitung / New Zurich Times . For English speakers, I recommend The Register from the UK for an excellent summary of these findings . Beginning in  February 27, 2012 , the controversial news organization Wikileaks has been publishing a large and growing trove of emails from the private intelligence firm  Strategic Forecasting, Inc (more widely known as  Stratfor). The leak pu...

For many years in the IT community, it was assumed that time spent travelling on an airplane was wasted. At best, you could make do with expensive and often-unreliable cell network coverage for connectivity. Even that was an issue, though, because of the airline's histrionic and decades-out-of-date concern that electronic devices interfered with flight navigation equipment. On top of having to pay a premium for unreliable service, you had to be sneaky about it, as well. Some of us handled the situation better than others So when in-flight internet services first started to become integrated to major airline fleets en masse, many tech people applauded. Those of us who had to attend trade shows, travel to meet customers or were responsible for multiple data center locations could get things done as we bounced back and forth across the country.  The bandwidth was every bit as expensive as roaming cell network charges, regularly more expensive, but the planes were being equipped ...

Oracle has released a Critical Security Patch for a long list of Oracle products. For MySQL specifically, the patch purports to resolve a multitude of vulnerabilities that allow remote execution without authentication, and impact nearly all versions of the database software. Oracle provided the following Risk Matrix to their MySQL customers, which outlines the CVE numbers of stated vulnerabilities, the component used by the vulnerability and a number of other details. I've included a copy of that Matrix for readers to review below. As the reader can clearly see, the risk for unpatched MySQL users is huge. A total of 154 vulnerabilities are addressed with this update. Some of these vulnerabilities reach a forehead-slapping CVSS score of 9.0 (just one point beneath the score for  the recent Shellshock bash vulnerability ). 24 of the patches are for MySQL. I highly advise anyone using MySQL or any Oracle product, including Java, to  update their software immediately. ...
