32TB of Windows 10 Internal Builds, Core Source Code Leak Online

According to an exclusive report via The Register, “a massive trove of Microsoft’s internal Windows operating system builds and chunks of its core source code have leaked online.” From the report: The data — some 32TB of installation images and software blueprints that compress down to 8TB — were uploaded to betaarchive.com, the latest load of files provided just earlier this week. It is believed the data has been exfiltrated from Microsoft’s in-house systems since around March. The leaked code is Microsoft’s Shared Source Kit: according to people who have seen its contents, it includes the source to the base Windows 10 hardware drivers plus Redmond’s PnP code, its USB and Wi-Fi stacks, its storage drivers, and ARM-specific OneCore kernel code. Anyone who has this information can scour it for security vulnerabilities, which could be exploited to hack Windows systems worldwide. The code runs at the heart of the operating system, at some of its most trusted levels. In addition to this, hundreds of top-secret builds of Windows 10 and Windows Server 2016, none of which have been released to the public, have been leaked along with copies of officially released versions.

Cisco Subdomain Private Key Found in Embedded Executable

Earlier this month, a developer accidentally discovered the private key of a Cisco subdomain. An anonymous reader shares the post: Last weekend, in an attempt to get Sky’s NOW TV video player (for Mac) to work on my machine, I noticed that one of the Cisco executables contains a private key that is associated with the public key in a trusted certificate for a cisco.com sub domain. This certificate is used in a local WebSocket server, presumably to allow secure Sky/NOW TV origins to communicate with the video player on the users’ local machines. I read the Baseline Requirements document (version 1.4.5, section 4.9.1.1), but I wasn’t entirely sure whether this is considered a key compromise. I asked Hanno Bock on Twitter, and he advised me to post the matter to this mailing list. The executable containing the private key is named ‘CiscoVideoGuardMonitor’, and is shipped as part of the NOW TV video player. In case you are interested, the installer can be found here (SHA-256: 56feeef4c3d141562900f9f0339b120d4db07ae2777cc73a31e3b830022241e6). I would recommend to run this installer in a virtual machine, because it drops files all over the place, and installs a few launch items (agents/daemons). The executable ‘CiscoVideoGuardMonitor’ can be found at ‘$HOME/Library/Cisco/VideoGuardPlayer/VideoGuardMonitor/ VideoGuardMonitor.bundle/Contents/MacOS/CiscoVideoGuardMonitor’. Certificate details: Serial number: 66170CE2EC8B7D88B4E2EB732E738FE3A67CF672, DNS names: drmlocal.cisco.com, Issued by: HydrantID SSL ICA G2. The issuer HydrantID has since communicated with the certificate holder Cisco, and the certificate has been revoked. Read more of this story at Slashdot.

Serious privilege escalation bug in Unix OSes imperils servers everywhere

Enlarge (credit: Victorgrigas ) A raft of Unix-based operating systems—including Linux, OpenBSD, and FreeBSD—contain flaws that let attackers elevate low-level access on a vulnerable computer to unfettered root. Security experts are advising administrators to install patches or take other protective actions as soon as possible. Stack Clash, as the vulnerability is being called, is most likely to be chained to other vulnerabilities to make them more effectively execute malicious code, researchers from Qualys, the security firm that discovered the bugs, said in a blog post published Monday . Such local privilege escalation vulnerabilities can also pose a serious threat to server host providers because one customer can exploit the flaw to gain control over other customer processes running on the same server. Qualys said it’s also possible that Stack Clash could be exploited in a way that allows it to remotely execute code directly. “This is a fairly straightforward way to get root after you’ve already gotten some sort of user-level access,” Jimmy Graham, director of product management at Qualys, told Ars. The attack works by causing a region of computer memory known as the stack to collide into separate memory regions that store unrelated code or data. “The concept isn’t new, but this specific exploit is definitely new.” Read 5 remaining paragraphs | Comments

NSA Links WannaCry To North Korea

An anonymous reader quotes a report from The Washington Post: The National Security Agency has linked the North Korean government to the creation of the WannaCry computer worm that affected more than 300, 000 people in some 150 countries last month, according to U.S. intelligence officials. The assessment, which was issued internally last week and has not been made public, is based on an analysis of tactics, techniques and targets that point with “moderate confidence” to North Korea’s spy agency, the Reconnaissance General Bureau, according to an individual familiar with the report. The assessment states that “cyber actors” suspected to be “sponsored by” the RGB were behind two versions of WannaCry, a worm that was built around an NSA hacking tool that had been obtained and posted online last year by an anonymous group calling itself the Shadow Brokers. Though the assessment is not conclusive, the preponderance of the evidence points to Pyongyang. It includes the range of computer Internet protocol addresses in China historically used by the RGB, and the assessment is consistent with intelligence gathered recently by other Western spy agencies. It states that the hackers behind WannaCry are also called “the Lazarus Group, ” a name used by private-sector researchers. Read more of this story at Slashdot.

Malicious Subtitles Threaten VLC, Kodi and Popcorn Time Users, Researchers Warn

Millions of people risk having their devices and systems compromised by malicious subtitles, according to a new research published by security firm Check Point. The threat comes from a previously undocumented vulnerability which affects users of popular streaming software, including Kodi, Popcorn-Time, and VLC. Developers of the applications have already applied fixes and in some cases, working on it. From a report: While most subtitle makers do no harm, it appears that those with malicious intent can exploit these popular streaming applications to penetrate the devices and systems of these users. Researchers from Check Point, who uncovered the problem, describe the subtitle ‘attack vector’ as the most widespread, easily accessed and zero-resistance vulnerability that has been reported in recent years. “By conducting attacks through subtitles, hackers can take complete control over any device running them. From this point on, the attacker can do whatever he wants with the victim’s machine, whether it is a PC, a smart TV, or a mobile device, ” they write. Read more of this story at Slashdot.

Google Found Over 1,000 Bugs In 47 Open Source Projects

Orome1 writes: In the last five months, Google’s OSS-Fuzz program has unearthed over 1, 000 bugs in 47 open source software projects… So far, OSS-Fuzz has found a total of 264 potential security vulnerabilities: 7 in Wireshark, 33 in LibreOffice, 8 in SQLite 3, 17 in FFmpeg — and the list goes on… Google launched the program in December and wants more open source projects to participate, so they’re offering cash rewards for including “fuzz” targets for testing in their software. “Eligible projects will receive $1, 000 for initial integration, and up to $20, 000 for ideal integration” — or twice that amount, if the proceeds are donated to a charity.
