Privatnost i sigurnost podataka i korisnika

[Night]

Ako tko ima potrebe za takvim nečim postoji Buskill, spoji se USB stick preko magnetskog konektora (par dolara na Aliju) i onda skripta u slučaju odspajanja trenutno okida shutdown, brisanje LUKS ili Vera headera ili što već treba da se onemogući pristup podacima. Ideja je ako ti netko otme laptop iz ruke da se odmah nukaju svi ključevi za enkripciju i tako zaštite privatni ključevi i ostale bitne informacije.

Šta će ti onda LUKS ?

[Night]

LUKS enkriptira podatke 256bitnim ključem, a taj ključ enkriptira šifrom (ili keyfileom) koji mu daš i koji imaš/znaš. Ta šifra ne mora nužno imati entropiju 256 bita, u pravilu je slabija od toga i onda ako se radi bruteforce raditi će se na headeru da se probije šifra i tako dođe do tog 256bit ključa jer direktni napad na 256bit ključ nije realano izvediv u trenutnom svemiru.

Tako ako si pobrisao header maknuo si taj vektor napada, kao i mogućnost da će netko izvući šifru od tebe i onda ostaje samo mogućnost da se bruteforca sam ključ enkripcije, a onda si nekih par milijardi godina miran

Ni wrench decryption metoda neće imati učinka https://xkcd.com/538/

Također smisao tog Buskilla je da napravi shutdown i tako počisti ključeve iz memorije i vrati disk u encrypted-at-rest stanje.

Several browser extensions with a combined total of more than 2.3 million downloads were reportedly hijacking browsing sessions and tracking user activity. Many of these malicious add-ons remained available on the Chrome and Edge web stores for years, with some even receiving the coveted "Featured" and "Verified" badges, raising serious questions about the extension review processes used by Google and Microsoft.
According to researchers at Koi Security, the malicious extensions were part of a coordinated operation involving at least 18 known add-ons listed on the Chrome and Edge extension stores. Dubbed "RedDirection," the browser hijacking campaign is believed to have infected more than 2.3 million users across both browsers, making it one of the largest operations of its kind ever documented.
One of the suspicious extensions, The Color Picker – Geco, had over 100,000 installs on Chrome and a 4.2-star rating from more than 800 reviews. It also received similarly high ratings on Microsoft's Edge Add-ons store, with over 1,000 installs, giving it an appearance of legitimacy.

Security researchers and ethical hackers are uncovering new and unexpected places where malicious code can be hidden within IT infrastructure. Even the seemingly innocuous Domain Name System (DNS) – the foundational naming system for all internet-connected devices – can, in theory, be exploited by clever cybercriminals or state-sponsored attackers. This underlines a growing trend: no part of the digital stack is too mundane to become a vector for sophisticated threats.
Hiding ransomware inside a CPU was strange but now, attackers are going even deeper and broader across networks. In a recent discovery, security researchers revealed that a piece of malware had been embedded directly within the Domain Name System, effectively bypassing nearly all advanced security tools.

As GenAI tools make their way into mainstream apps and workflows, serious concerns are mounting about their real-world safety. Far from boosting productivity, these systems are increasingly being exploited – benefiting cybercriminals and cost-cutting executives far more than end users. Researchers this week uncovered how Google's Gemini model used in Gmail can be subverted in an incredibly simple way, making phishing campaigns easier than ever.
Mozilla recently unveiled a new prompt injection attack against Google Gemini for Workspace, which can be abused to turn AI summaries in Gmail messages into an effective phishing operation. Researcher Marco Figueroa described the attack on 0din, Mozilla's bug bounty program for generative AI services.
We strongly recommend reading the full report if you still think GenAI technology is ready for deployment in production or live, customer-facing products.

FortiGuard Labs researchers have uncovered a sophisticated cryptomining campaign where the H2Miner botnet, active since late 2019, has expanded its operations to target Linux, Windows, and containerized environments simultaneously.
The campaign represents a significant evolution in cross-platform cryptocurrency mining attacks, with threat actors leveraging updated scripts and infrastructure to maximize financial gains from compromised systems.
The investigation revealed that H2Miner operators have updated their arsenal with new deployment URLs while maintaining core functionalities from previous campaigns documented in 2020.

Pa instaliraj im ovo ili neki neki anti-malware DNS.
Ja nisam penzić pa ipak koristim oboje.

BTW, reagirali su i glavonje, mašala.

Slozio sam im vec nextdns pa kroz njega odrzavam te liste. Ima zgodan feature da moze blokirati novokreirane domene do 30 dana starosti (ovi spomenuti primjeri su automatski bili blokirani jer su dosta novi sajtovi), ali nikad ne znas... Ako domena pozivi duze, dobro ju je imati u blacklisti.

ASUS Republic of Lamers
Nikad ne instaliram pored drivera i nekakve gluposti koje proizvođač forsira, tipa nVidia Experience, Asus driver hub ili kako se već njihova verzija tog spywarea zove.

[mkey]

Poanta i jeste u tome da su oni to svoje govno ubacili u MBO (nemam pojma na koji način) tako da ne moraš ništa niti instalirati ručno.

[The Exiled]

Ugrađeno je direktno u BIOS, samo su jednog dana s novom verzijom i to sranje ubacili, a čim se Windows OS instalira, odmah je u pozadini uključen Armoury Crate servis.

I godinama se pričalo da je to malware/spyware koji samo čeka da se upogoni kak spada i onda kad im se točno to desilo, u ASUSu se prave Englezi.

Naravno i drugi proizvođači ploča su kopirali takvu implementaciju za svoje ideje, makar se može isključiti u BIOS-u, ali većina ih to ostavi uključeno po defaultu.

[kopija]

Koja je to opcija u biosu?

[The Exiled]

ASUS Armoury Crate, prvi put sam skužil da se pojavila prilikom nadogradnje BIOS-a za prijašnju B350 ploču, dok je kasnije, ali u ono vrijeme nova B450 ploča već došla s tim.

Sad na ovim MSI B650 kojem imam, postoji slično, samo u njihovoj režiji. Kak god se okrene, smetje koje su svi veći proizvođači progurali svaki na svoj način.

[tomek@vz]

Glavno da imamo UEFI Bios sa Secure Boot-om. Ne sjećam se da je netko ovakve egzibicije radio u starim vremenima (naravno ako griješim - ispravite me).

[The Exiled]

Krenulo je unatrag skoro 15 godina, prvo opet s ASUSom kad su implementirali MCE, tak da lakše budu bolji od ostalih u recenzijama. Kasnije su i drugi proizvođači složili slične stvari, pa su opet svi došli na isto, a u međuvremenu ih je to sve dostiglo skupa s Intelom i Raptor Lake serijom. Danas imamo ovakve pizdarije, jer svaki proizvođač matičnih ploča mora istovremeno nuditi all-in-one rješenja za sve kaj prodaju, od kontrole RGB žaruljica i ventilatora (1 -2), prek skidanja drivera, do aplikacija koje služe kao poveznica između svog tog bloatware, spyware i malware smeća.

Microsoft will stop using China-based engineers to support U.S. military cloud services after a ProPublica report revealed their involvement, prompting backlash from Senator Tom Cotton and a two-week Pentagon review ordered by Defense Secretary Pete Hegseth. In response, Hegseth announced an immediate ban on any Chinese involvement in Department of Defense cloud contracts. Reuters reports:
The report detailed Microsoft's use of Chinese engineers to work on U.S. military cloud computing systems under the supervision of U.S. "digital escorts" hired through subcontractors who have security clearances but often lacked the technical skills to assess whether the work of the Chinese engineers posed a cybersecurity threat. [Microsoft] told ProPublica it disclosed its practices to the U.S. government during an authorization process.

On Friday, Microsoft spokesperson Frank Shaw said on social media website X the company changed how it supports U.S. government customers "in response to concerns raised earlier this week ... to assure that no China-based engineering teams are providing technical assistance" for services used by the Pentagon.

Secure Boot je najbolja stvar koja se pojavila na security sceni u zadnjem desetljeću.

"The U.S. is absolutely facing the most serious Chinese hacking ever." That's what the Washington Post was told by a China-focused consultant at security company SentinelOne:
Undeterred by recent indictments alleging widespread cyberespionage against American agencies, journalists and infrastructure targets, Chinese hackers are hitting a wider range of targets and battling harder to stay inside once detected, seven current and former U.S. officials said in interviews. Hacks from suspected Chinese government actors detected by the security firm CrowdStrike more than doubled from 2023 to more than 330 last year and continued to climb as the new administration took over, the company said... Although the various Chinese hacking campaigns seem to be led by different government agencies and have different goals, all benefit from new techniques and from Beijing's introduction of a less constrained system for cyber offense, the officials and outside researchers told The Washington Post... Chinese intelligence, military and security agencies previously selected targets and tasked their own employees with breaking in, they said. But the Chinese government decided to take a more aggressive approach by allowing private industry to conduct cyberattacks and hacking campaigns on their own, U.S. officials said.

The companies are recruiting top hackers who discover previously unknown, or "zero-day," flaws in software widely used in the United States. Then the companies search for where the vulnerable programs are installed, hack a great many of them at once, and then sell access to multiple Chinese government customers and other security companies. That hacking-for-hire approach creates hundreds of U.S. victims instead of a few, making it hard to block attacks and to decide which were China's key targets and which were unintentionally caught in the hacks, an FBI official said, speaking on the condition of anonymity to follow agency practices... "The result of that incentive structure is that there is significantly more hacking...."

China has mastered the ability to move undetected through networks of compromised U.S. devices, so that the final connection to a target appears to be an ordinary domestic connection. That makes it easy to get around technology that blocks overseas links and puts it outside the purview of the National Security Agency, which by law must avoid scrutinizing most domestic transmissions. Beijing is increasingly focused on hacking software and security vendors that provide access to many customers at once, the FBI official said. Once access is obtained, the hackers typically add new email and collaboration accounts that look legitimate... Beyond the increased government collaboration with China's private security sector is occasional collaborating with criminal groups, said Ken Dunham, an analyst at the security firm Qualys.

The article notes that China's penetration of U.S. telecom carriers "is still not fully contained, according to the current and former officials." But in addition, the group behind that attack "has more recently shown up inside core communications infrastructure in Europe, according to John Carlin, a former top national security official in the Justice Department who represents some U.S. victims of the group." And documents leaked last year from a security contractor that works with the Chinese military and other government groups "described contracts and targets in 20 countries, with booty including Indian immigration data, logs of calls in South Korea, and detailed information on roads in Taiwan.

"It also detailed prices for some services, such as $25,000 for promised remote access to an iPhone, payment disputes with government customers and employee gripes about long hours..."

kažeš "hakiraju nas, ali nismo skroz sigurni, jer ne ostavljaju tragove"

No ono šta mi je super je kako oni ne hakiraju kineze.

Nemaju brige, dokle god im je ovaj stručLJak na raspolaganju za sva tehnička pitanja.

Izuzev toga, Amerika sve proizvodi sama, potpuno su neovisni o ostataku svijeta, cijeli kontinent im je pun tvornica za domaću proizvodnju u čemu prednjači Intel kao firma koja je u topu vrhova svega vezanog za poluvodiče, tak da Kinezi i ono malo kaj uspiju hakirati, to imaju više sreće, nego pameti.
