Elastic 披露 KREMLIN 多阶段窃密工具包,针对巴西银行用户,投放恶意浏览器扩展与 RAT。
完整感染链(JS 加载器→PE 注入→扩展/RAT)拆解,检测思路可迁移。
KREMLIN is a multi-stage credential theft toolkit targeting Brazilian banking users.
New research from Elastic Security Labs (REF9334): https://t.co/0QDgJEmYho by @cyril_t_f and @andythevariable
The infection chain combines JavaScript loaders, an optional PE injector, and a custom C++ installer. The installer downloads and installs a malicious browser extension for Chrome and Edge and/or deploys an embedded PULSAR or REMCOS RAT. This malicious extension is then used for web-browser data interception and exfiltration.
KREMLIN resolves its C2 endpoints from Ethereum. Smart contracts store payload URLs and extension download locations as on-chain key-value pairs. The operators update endpoints by writing a new transaction.
The extension installation bypasses Chromium's integrity system. The installer launches Chrome under a debugger, recovers the App-Bound OSCrypt key from process memory, extracts the seed from resources.pak, then regenerates the HMACs and encrypted SHA-256 hashes that Secure Preferences requires. The extension registers silently with developer mode forced on.
Once active, it logs input fields, intercepts HTTP requests by configurable URL and method rules, injects attacker-controlled HTML, and exfiltrates intercepted data, cookies, and credentials over WebSocket and HTTP.
Elastic Security Labs Threat Command registered the network canary domain that operates as a kill switch. We observed thousands of implants from Brazil attempting to check in to this domain. Once this domain was live, the KREMLIN loaders crash before trying to update or install the final payload, temporarily disrupting this campaign.
The targeting is clear. Lure filenames impersonate PIX transfers, bank statements, and receipts from Banco do Brasil, Bradesco, Sicoob, Santander, C6 Bank, and PagBank. Ethereum transaction timestamps cluster in São Paulo working hours. Portuguese-language artifacts appear throughout the codebase.

Google 搜索结果改用 google.com/goto?url= 编码跳转,链接目标难以肉眼核验。

🚨 𝗗𝗲𝗳𝗲𝗻𝗱𝗲𝗿 𝗔𝗹𝗲𝗿𝘁: 𝗡𝗲𝘄 𝗚𝗼𝗼𝗴𝗹𝗲 𝗥𝗲𝗱𝗶𝗿𝗲𝗰𝘁 𝗨𝗥𝗟𝘀 𝗙𝗼𝗿𝗺𝗮𝘁
A recent change introduces google[.]com/goto?url=... redirects for some search results, replacing direct website links. The target address is encoded in a proprietary format rather than displayed as a readable URL, making it more difficult for users to identify and verify a link's destination before clicking.
Over the past two days, analysis of sandbox results from @anyrun_app has revealed that several of these google[.]com/goto redirect URLs have been identified as malicious. The redirects ultimately led to harmful destinations, demonstrating how attackers may abuse the new redirection mechanism to conceal malicious content behind seemingly legitimate Google URLs.

德国 Wunstorf 空军基地附近坠毁一架无人机,警方展开大规模调查。
RT @InsiderGeo: NEW: 🇩🇪 A drone has crashed in Germany, just around 1 kilometre from a Bundeswehr military air base in Wunstorf, Lower Saxony,
Wunstorf Air Base is the home of the German Air Force’s 62nd Air Transport Wing (LTG 62), which operates the Bundeswehr’s Airbus A400M transport fleet. It is the main base for Germany’s A400Ms and serves as a major hub for military air transport, including logistics, troop transport, MEDEVAC and aerial refuelling missions.
Police are conducting a major operation after debris from the drone was discovered east of Lake Steinhude. Officers are searching the area for additional wreckage.
The drone came down in an open, uninhabited area, and authorities currently say there are no indications of a danger to the public.
However, the origin of the drone remains unknown. Investigators are working to recover and analyse more debris to determine what type of drone it was.

vx-underground 将迁移全部源码并增强恶意软件论文检索。
RT @vxunderground: For several months now I've been slowly, but surely, working behind the scenes to dramatically enhance vx-underground.
I still don't have a definitive timeline, but I would like to share some stuff coming.
1. All source code will be moved from GitHub to vx-underground. The new vx-underground will have functionality to search through code bases by keywords for research, filter by language type, yada yada yada.
2. Enhanced malware paper searching. It'll be easier to search for stuff now.
3. API access to verified individuals. This is designed for researchers, or organizations, who may want the ability to perform large downloads programmatically.
4. Paid tier. vx-underground will remain free for everyone. However, if you're an organization which makes more than $1,000,000/year you will have to pay for some functionality (malware sample API downloads). I will not charge thousands of dollars, I'm not greedy, but some of you large companies are jerks and need to pay up for scraping the site for AI and samples. API access will be free for individual researchers, small businesses, students, non-profits, and government institutions. Unfortunately, I've learned the hard way large for-profit organizations will not donate.
5. I've heard your complaints for YEARS. We are looking for a HTML-only vx-underground implementation, probably as a subdomain or something. I'm well aware you hardcore nerds hate JavaScript. I will continue investigating this.
6. We're working on our 4th book, Black Mass Volume IV.
I have more to announce, but some details are still up in the air. These changes likely won't appear until ... I don't know, bro. I've got a full time job and a family. I'm thinking probably late 2026, early 2027.
Thank you to our donors and sponsors that make this possible. I'm not as speedy as I used to be with updates, but I'm still cooking.

用 RDMA 把 DGX Spark 与 Mac Studio 互联跑大模型的实验设想。
RT @MiaAI_lab: Ash is building a direct link between DGX Sparks and a Mac Studio. He's got Metal and CUDA moving data over real RDMA.
The idea: let the Sparks handle the heavy prompt processing while the Studio generates tokens - so together they could outperform either setup on its own.
That's 256 GB on the Studio + 128 GB per DGX Spark = 512 GB total. A ~400 GB model wouldn't fit on either system alone, but it could potentially run across all three if the split works.
Seriously impressive stuff!

讨论 AI Agent 扩大攻击面、对形式化验证持悲观态度的观点。
RT @S1r1u5_: i hope this is true, but i am quite pessimistic about it. intuitively it still seems offence dominant to me. there is already a huge amount of attack surface from the vast amount of software and code we have, and now agents are adding even more while becoming part of the attack surface themselves.
i am also pessimistic about formal verification for various reasons. software intent is not clear unlike math, huge amount of state space with interconnected component etc
and software bugs are not even the only way to attack things. you have social engineering, and now prompt injection etc.
claims like “we found all the p0s” seem absurd and wrong threat model to be working with.
i generally think a good way to deal with cyber threats is to just assume everything will eventually get pwned and build things around that assumption. reduce the scope, isolate things, limit privileges, etc,

and my thoughts on formal verification shared in below tweet.
my hunch is we underestimate the complexity of software, like we can only understand what we have the ability to, i feel same applies to ai.
i feel like every new generation of ai opens up more of the vulnerability space that was always there but we simply its not intelligent enough to find.
so i think the safer bet is to assume you will eventually get pwned rather than rely on the assumption that you have exhausted the vulnerability space. especially when the attacker has incentive to keep throwing increasingly intelligent ai at finding the thing you missed.
讨论 AI 持续找漏洞并自动打补丁才能实现防御占优。
yea on defence dominance, i am probably underestimating it, if continuously running ai can find bugs and also write a patch without breaking and introducing new bugs(which is the main bottleneck) then ig software would get secure. this requires a world where software entirely run by ai without human middleman otherwise it will be just slow, amdahl law.

Led to some interesting thoughts about value of distillation, what it takes to do distillation effectively, and what kinds of model behaviors are hard to extract from distillation.

观点:AI 抬高了攻击下限,但顶尖成果仍依赖强团队与情报积累。
RT @HackingLZ: I’m a fan of people discussing offensive capabilities and what models can now do. At the same time, the people getting the best results from models have extremely strong and talented teams behind them.
AI raised the floor, but many people didn’t know where the floor already was because they weren’t reading CTI, DFIR reports (@TheDFIRReport ), attacker playbooks, or leaked attacker chat logs. A lot of “real” intrusions were never especially sophisticated.
Many organizations have meaningfully improved their security over the years. Others were forced into the game by ransomware, which turned otherwise junk intrusions with little payoff into multimillion dollar businesses. If ransomware and extortion disappeared tomorrow, plenty of smaller organizations would still have compliance and good faith reasons to invest in security, but not the existential fear driving them today.
Machine speed is great and all, but ransomware groups still have to strike some balance between making money and becoming enough of a priority to get their doors kicked in. It’s also worth reminding people that the attacks causing the most sleepless nights so far this year have been supply chain compromises, not agents speed running commodity exploits.
Proton 调查 7000 余款美国区 VPN 应用,85% 含追踪器收集共享个人数据。
RT @T3chFalcon: Proton surveyed over 7,000 mobile VPN apps available in the US.
85% of VPNs downloaded in the US contain trackers that collect and share your personal data. your device ID. your network type. your mobile carrier. your usage patterns. all sent to third parties.
64 of those apps are owned by Chinese companies. under Chinese law, companies must share user data with the government on request. 31 of those 64 Chinese-owned VPNs hide their real ownership behind shell companies in Singapore, Hong Kong, and the UK.
64 VPN apps actively track your physical location using GPS. the tool you installed to protect your privacy is tracking where you physically are. some of those are among the most downloaded VPNs in the US — VPN Proxy Master, X-VPN, VPN-Fast.
trackers in US VPN apps send data to:
— China: 1.5 million downloads a month
— Russia: 1.4 million downloads a month
— Israel: 2.6 million downloads a month
Apple and Google let all of this into their app stores. they check that a privacy policy exists. they don't audit whether the app actually follows it.
What to look for in a trustworthy VPN:
— independently audited no-logs policy
— open-source code
— avoid free options
Proton VPN (open source, Independently audited — (https://t.co/eqhbG0Tnnm).
the VPN that tracks where you go is worse than no VPN at all.

this was me few years back, the pain of approaching a new target and writing an n-day exploit used to be a lot. i would spend days just understanding all the new things the target had implemented(like the v8 sandbox, windows exp here)then more days figuring out everything else and improvising around it.
it was literal grunt work, but it was beautiful, time would just disappear, you had a clear goal, you got feedback at every step, and you kept hillclimbing until you got there. i had some of the most fun in my life doing this kind of work.
unfortunately, that is changing now, i don't need to spend my time on this, this is all just largely automated.
