New Olympic Discipline: Hive Hunting This week, community contributor Hakyac added a new Olympic discipline to Metasploit exploit sport category, which is based on the work of community security researchers @jonasLyk and Kevin Beaumont ). The rules are simple: You need to abuse a flaw in Windows 10 and 11 configuration to pass through the defense and access Security Account Manager (SAM) files. Any local unprivileged player is able to read this sensitive security information, such as hashes of user/admin passwords. The best strategy to win a gold medal is to start abusing Windows Volume Shadow Copy Service (VSS) to access these files and copy them locally. Finally, you just need to dump the NTLM hashes, use them in a pass-the-hash attack and score with a remote code execution. Note that Microsoft issued an out-of-band advisory and tracked this vulnerability as CVE-2021-36934 . You can find more information about the rules in this blog post . Happy Hive hunting!

The time has come for me to find a new home for my (paper) cryptography library. It’s about 150 linear feet of books, conference proceedings, journals, and monographs — mostly from the 1980s, 1990s, and 2000s. My preference is that it goes to an educational institution, but will consider a corporate or personal home if that’s the only option available. If you think you can break it up and sell it, I’ll consider that as a last resort. New owner pays all packaging and shipping costs, and possibly a purchase price depending on who you are and what you want to do with the library. If you are interested, please email me. I can send photos. from Schneier on Security https://www.schneier.com/blog/archives/2021/07/i-am-parting-with-my-crypto-library.html

Editor’s Note : The following post is an excerpt of a full report. To read the entire analysis, click here to download the report as a PDF. Executive Summary A Recorded Future client provided information to Insikt Group relating to a potential security incident triggered by a software application called “Beijing One Pass”. This Chinese government-backed application enables access to state benefits information and was downloaded by employees of the Recorded Future client after they were informed that paper copies of the information would no longer be available. Insikt Group independently verified that the installed application exhibits characteristics consistent with potentially unwanted applications (PUA) and spyware. The software is associated with the Beijing Certificate Authority (北京数字认证股份有限公司), which is a Chinese state-owned enterprise (BJCA, www.bjca[.]cn).  Some notable suspicious behaviors relate to several dropped files and subsequent processes initiated from the prim...

New paper: “ Encrypted Cloud Photo Storage Using Google Photos “: Abstract: Cloud photo services are widely used for persistent, convenient, and often free photo storage, which is especially useful for mobile devices. As users store more and more photos in the cloud, significant privacy concerns arise because even a single compromise of a user’s credentials give attackers unfettered access to all of the user’s photos. We have created Easy Secure Photos (ESP) to enable users to protect their photos on cloud photo services such as Google Photos. ESP introduces a new client-side encryption architecture that includes a novel format-preserving image encryption algorithm, an encrypted thumbnail display mechanism, and a usable key management system. ESP encrypts image data such that the result is still a standard format image like JPEG that is compatible with cloud photo services. ESP efficiently generates and displays encrypted thumbnails for fast and easy browsing of photo galleries from...

This massive increase in the number of victim organizations being named demonstrates the harsh reality of how far ransomware threat actors will actually go if ransoms aren’t paid. from KnowBe4 Security Awareness Training Blog https://blog.knowbe4.com/over-700-ransomware-victim-organizations-are-named-on-data-leak-sites-in-q2

Every time there is another data breach, we are asked to change our password at the breached entity. But the reality is that in most cases by the time the victim organization discloses an incident publicly the information has already been harvested many times over by profit-seeking cybercriminals. Here’s a closer look at what typically transpires in the weeks or months before an organization notifies its users about a breached database. Our continued reliance on passwords for authentication has contributed to one toxic data spill or hack after another. One might even say passwords are the fossil fuels powering most IT modernization: They’re ubiquitous because they are cheap and easy to use, but that means they also come with significant trade-offs — such as polluting the Internet with weaponized data when they’re leaked or stolen en masse. When a website’s user database gets compromised, that information invariably turns up on hacker forums. There, denizens with computer rigs that a...

A teenager on an airplane sent a photo of a replica gun via AirDrop to everyone who had their settings configured to receive unsolicited photos from strangers. This caused a three-hour delay as the plane — still at the gate — was evacuated and searched. The teen was not allowed to reboard.

The cybercriminal underground is becoming increasingly organized, according to researchers at HP. The criminal underground functions like a regular economy, with people selling goods and services such as phishing kits, malware, and access to compromised networks.

This is important : Monsignor Jeffrey Burrill was general secretary of the US Conference of Catholic Bishops (USCCB), effectively the highest-ranking priest in the US who is not a bishop, before records of Grindr usage obtained from data brokers was correlated with his apartment, place of work, vacation home, family members’ addresses, and more. […] The data that resulted in Burrill’s ouster was reportedly obtained through legal means. Mobile carriers sold­ — and still sell — ­location data to brokers who aggregate it and sell it to a range of buyers, including advertisers, law enforcement , roadside services, and even bounty hunters . Carriers were caught in 2018 selling real-time location data to brokers , drawing the ire of Congress. But after carriers issued public mea culpas and promises to reform the practice, investigations have revealed that phone location data is still popping up in places it shouldn’t . This year, T-Mobile even broadened its offerings , selling customers...

Today, Rapid7 is disclosing 9 vulnerabilities that affect 3 open-source projects: EspoCRM , Pimcore , and Akaunting . Right out of the gate, I'd like to give a special thanks to these 3 open-source project maintainers. While it's never great to learn of new vulnerabilities in your own product, all 3 project maintainers accepted, validated, and provided fixes for these vulnerabilities within one day , which is amazing when it comes to vulnerability disclosure. EspoCRM was notified on May 4, 2021 and patched source on May 5; Akaunting, on May 13 and turned it around on May 14; and Pimcore validated their vulnerabilities on April 29 after learning about them on April 28, 2021. Nice work, all around. Now, I'm not sure why open source is just so much faster than the typical proprietary software vuln-patching pipeline, at least for the disclosures I've been involved in. It might be because, in open source, you're almost guaranteed to have your first communication with a...
