'A leaker today posted on Twitter a link to a file sharing service that contains what an anonymous source claims is a portion of Intel's crown jewels: A 20GB folder of confidential Intel intellectual property. The leaker dubbed the release the "Intel exconfidential Lake Platform Release ;)" The folder has been posted by an anonymous source that claims more is coming soon, and while we don't know the exact specifics of the folder's contents, we have verified that it does exist. In fact, the title of many of the documents do correlate to the list of purported information posted by the leaker: Intel ME Bringup guides + (flash) tooling + samples for various platforms Kabylake (Purley Platform) BIOS Reference Code and Sample Code + Initialization code (some of it as exported git repos with full history) Intel CEFDK (Consumer Electronics Firmware Development Kit (Bootloader stuff)) SOURCES Silicon / FSP source code packages for various platforms Various Intel Development and Debugging Tools Simics Simulation for Rocket Lake S and potentially other platforms Various roadmaps and other documents Binaries for Camera drivers Intel made for SpaceX Schematics, Docs, Tools + Firmware for the unreleased Tiger Lake platform (very horrible) Kabylake FDK training videos Intel Trace Hub + decoder files for various Intel ME versions Elkhart Lake Silicon Reference and Platform Sample Code Some Verilog stuff for various Xeon Platforms, unsure what it is exactly. Debug BIOS/TXE builds for various Platforms Bootguard SDK (encrypted zip) Intel Snowridge / Snowfish Process Simulator ADK Various schematics Intel Marketing Material Templates (InDesign)' -- source: https://slashdot.org/story/20/08/06/199225 Cheers, Peter -- Peter Reutemann Dept. of Computer Science University of Waikato, NZ +64 (7) 858-5174 http://www.cms.waikato.ac.nz/~fracpete/ http://www.data-mining.co.nz/

Chrome for Android May Soon Send Notifications Reminding You To Use Chrome
by Peter Reutemann 06 Aug '20

06 Aug '20

'For years now, Google Chrome has been an absolute dominant force in the world of web browsers, but since the relaunch of Microsoft Edge based on Google's Chromium, that position has been challenged. Now, Google is preparing to drive more Android owners back to using Chrome through targeted notifications. Over the admittedly brief history of the Internet, there have been a number of fierce competitions, commonly called "browser wars," between companies, in an effort to get more people to use their particular web browser. Mozilla and Netscape waged war against Internet Explorer, and Chrome fought and won against Firefox. Most recently, Microsoft Edge and Samsung Internet have begun to wage war against Chrome on desktop and Android respectively. Now, we've found that Google is preparing to try and win back some of those who have left Chrome for other browsers, starting on Android. Based on our reading of a series of code changes, we believe Google Chrome for Android will send you a notification if you haven't used Chrome in a while.' -- source: https://it.slashdot.org/story/20/08/05/2022204 Cheers, Peter -- Peter Reutemann Dept. of Computer Science University of Waikato, NZ +64 (7) 858-5174 http://www.cms.waikato.ac.nz/~fracpete/ http://www.data-mining.co.nz/

Hackers Could Use IoT Botnets To Manipulate Energy Markets
by Peter Reutemann 06 Aug '20

06 Aug '20

'Wired: At the Black Hat security conference on Wednesday, [researchers at the Georgia Institute of Technology] will present their findings, which suggest that high-wattage IoT botnets -- made up of power-guzzling devices like air conditioners, car chargers, and smart thermostats -- could be deployed strategically to increase demand at certain times in any of the nine private energy markets around the US. A savvy attacker, they say, would be able to stealthily force price fluctuations in the service of profit, chaos, or both. The researchers used real, publicly available data from the New York and California markets between May 2018 and May 2019 to study fluctuations in both the "day-ahead market" that forecasts demand and the "real-time market," in which buyers and sellers correct for forecasting errors and unpredictable events like natural disasters. By modeling how much power various hypothetical high-wattage IoT botnets could draw, and crunching the market data, the researchers devised two types of potential attacks that would alter energy pricing. They also figured out how far hackers would be able to push their attacks without the malicious activity raising red flags. "Our basic assumption is that we have access to a high-wattage IoT botnet," says Tohid Shekari, a PhD candidate at the Georgia Institute of Technology who contributed to the research, along with fellow PhD candidate Celine Irvine and professor Raheem Beyah. "In our scenarios, attacker one is a market player; he's basically trying to maximize his own profit. Attacker two is a nation-state actor who can cause financial damage to market players as part of a trade war or cold war. The basic part of either attack is to look at price-load sensitivity. If we change demand by 1 percent, how much is the price going to change as a result of that? You want to optimize the attack to maximize the gain or damage." An attacker could use their botnet's power to increase demand, for instance, when other entities are betting it will be low. Or they could bet that demand will go up at a certain time with certainty that they can make that happen. "The researchers caution that, based on their analysis, much smaller demand fluctuations than you might expect could affect pricing, and that it would take as few as 50,000 infected devices to pull off an impactful attack," the report adds. "Consumers whose devices are unwittingly conscripted into a high-wattage botnet would also be unlikely to notice anything amiss; attackers could intentionally turn on devices to pull power late at night or while people are likely to be out of the house. [...] The researchers calculated that market manipulation campaigns would cause, at most, a 7 percent increase in consumers' home electric bills, likely low enough to go unnoticed." The researchers say market manipulators could take home as much as $245 million a year, and cause as much as $350 million per year in economic damage.' -- source: https://hardware.slashdot.org/story/20/08/04/2213253 Cheers, Peter -- Peter Reutemann Dept. of Computer Science University of Waikato, NZ +64 (7) 858-5174 http://www.cms.waikato.ac.nz/~fracpete/ http://www.data-mining.co.nz/

LastPass Will Warn You If Your Passwords Show Up On the Dark Web
by Peter Reutemann 06 Aug '20

06 Aug '20

'LastPass is updating its Security Dashboard with a feature that provides an overview of all your accounts, highlighting any passwords that could pose a security risk. The password manager is also introducing dark web monitoring, although it will require you to be a paid LastPass subscriber. Engadget reports: If you already use LastPass and the Security Dashboard sounds familiar, it's because it builds on the Security Challenge functionality LastPass developer LogMeIn added in 2010. As before, grading is a major aspect of the interface. When you first navigate to the Security Dashboard, you'll see a score of all your logins, followed by a breakdown of passwords that are either old, inactive, weak or reused. You can click or tap on a problematic password to change it, and LastPass will automatically take you to the webpage where you can update your login information. LogMeIn hasn't changed how the app calculates the overall score it gives to each user. But one significant improvement the Security Dashboard brings over the Security Challenge is that you don't need to manually run it each time you want to see the security of your online accounts. The score and steps you can take to improve your online security are there each time you visit that part of the software's interface. With today's update, LogMeIn is also introducing dark web monitoring. When you enable the feature, LastPass will proactively check your online accounts against Enzoic's compromised credentials database. If it detects an issue, it will notify you through both email and the app. Dark web monitoring is available to LastPass Premium, Family and Business subscribers. The dashboard, by contrast, is available to all LastPass users.

Hacker Leaks Passwords For 900+ Enterprise VPN Servers
by Peter Reutemann 06 Aug '20

06 Aug '20

'A hacker has published today a list of plaintext usernames and passwords, along with IP addresses for more than 900 Pulse Secure VPN enterprise servers. ZDNet reports: According to a review, the list includes: IP addresses of Pulse Secure VPN servers, Pulse Secure VPN server firmware version, SSH keys for each server, a list of all local users and their password hashes, admin account details, last VPN logins (including usernames and cleartext passwords), and VPN session cookies. Bank Security, a threat intelligence analyst specialized in financial crime [...] noted that all the Pulse Secure VPN servers included in the list were running a firmware version vulnerable to the CVE-2019-11510 vulnerability. Bank Security believes that the hacker who compiled this list scanned the entire internet IPv4 address space for Pulse Secure VPN servers, used an exploit for the CVE-2019-11510 vulnerability to gain access to systems, dump server details (including usernames and passwords), and then collected all the information in one central repository. Making matters worse, the list has been shared on a hacker forum that is frequented by multiple ransomware gangs. For example, the REvil (Sodinokibi), NetWalker, Lockbit, Avaddonm, Makop, and Exorcist ransomware gangs have threads on the same forum, and use it to recruit members (developers) and affiliates (customers). Many of these gangs perform intrusions into corporate networks by leveraging network edge devices like Pulse Secure VPN servers, and then deploy their ransomware payload and demand huge ransom demands. As Bank Security told ZDNet, companies have to patch their Pulse Secure VPNs and change passwords with the utmost urgency.

Twitter Says Android Security Bug Gave Access To Direct Messages
by Peter Reutemann 06 Aug '20

06 Aug '20

'Twitter says a security bug may have exposed the private direct messages of its Android app users, but said that there was no evidence that the vulnerability was ever exploited. From a report: The bug could have allowed a malicious Android app running on the same device to siphon off a user's direct messages stored in the Twitter app by bypassing Android's in-built data permissions. But, Twitter said that the bug only worked on Android 8 (Oreo) and Android 9 (Pie), and has since been fixed. A Twitter spokesperson told TechCrunch that the bug was reported by a security researcher "a few weeks ago" through HackerOne, which Twitter uses for its bug bounty program. "Since then, we have been working to keep accounts secure," said the spokesperson. "Now that the issue has been fixed, we're letting people know." Twitter said it waited to let its users know in order to prevent someone from learning about the issue and taking advantage of it before it was fixed.' -- source: https://yro.slashdot.org/story/20/08/05/1728253 Cheers, Peter -- Peter Reutemann Dept. of Computer Science University of Waikato, NZ +64 (7) 858-5174 http://www.cms.waikato.ac.nz/~fracpete/ http://www.data-mining.co.nz/

Cambridge University Goes Microsoft
by Lawrence D'Oliveiro 05 Aug '20

05 Aug '20

Cambridge University, one of the pioneering centres of computer science research (since 1937), is retiring its in-house Hermes e-mail system in favour of moving completely to Microsoft Exchange Online <https://www.theregister.com/2020/08/04/cambridge_uni_decommissioning_hermes…>. Admin David McBride argues that Microsoft “does not implement IETF standards – at least not competently". In particular, he said: "Its IMAP service implementation is sufficiently poor as to lose data in practice, its mail handling has been seen to violate RFC MUST assertions that causes cryptographic email signatures to be rendered invalid, and it has even sometimes generated outbound email that contains invalid MIME data." He added: "Email services that do not competently support IETF standards, such as SMTP, IMAP, MIME and the like, present significant interoperability challenges and will risk leaving us locked in to using a single vendor." According to the info here <https://fanf2.user.srcf.net/photos.html> (linked from a reader comment), Hermes is not some kind of homebrew proprietary system; it is built on well-known open-source components such as Exim and Cyrus.

Windows 10: HOSTS File Blocking Telemetry Is Now Flagged As a Risk
by Peter Reutemann 05 Aug '20

05 Aug '20

'Starting at the end of July, Microsoft has begun detecting HOSTS files that block Windows 10 telemetry servers as a 'Severe' security risk. Windows 10 users are reporting that Windows Defender had started detectingmodified HOSTS files as a 'SettingsModifier:Win32/HostsFileHijack' threat. So it seems that Microsoft had recently updated their Microsoft Defender definitions to detect when their servers were added to the HOSTS file. Users who utilize HOSTS files to block Windows 10 telemetry suddenly caused them to see the HOSTS file hijack detection. Users who intentionally modify their HOSTS file can allow this 'threat,' but it may enable all HOSTS modifications, even malicious ones, going forward.' -- source: https://tech.slashdot.org/story/20/08/04/143248 Cheers, Peter -- Peter Reutemann Dept. of Computer Science University of Waikato, NZ +64 (7) 858-5174 http://www.cms.waikato.ac.nz/~fracpete/ http://www.data-mining.co.nz/

Firefox 79 Clears Redirect Tracking Cookies Every 24 Hours
by Peter Reutemann 05 Aug '20

05 Aug '20

'Mozilla today started rolling out Enhanced Tracking Protection (ETP) 2.0 in Firefox. While the company technically launched Firefox 79 for Windows, Mac, and Linux last week, it only unveiled its marquee feature today. Firefox 79 by default blocks redirect tracking, also known as bounce tracking, and adds a handful of new developer features. [...] Since enabling Enhanced Tracking Protection by default, Mozilla says it has blocked 3.4 trillion tracking cookies. But the company notes the ad industry has since created workarounds and new ways to collect user data as you browse the web.' -- source: https://news.slashdot.org/story/20/08/04/176239 Cheers, Peter -- Peter Reutemann Dept. of Computer Science University of Waikato, NZ +64 (7) 858-5174 http://www.cms.waikato.ac.nz/~fracpete/ http://www.data-mining.co.nz/
