File Archiver In The Browser

This article explores a phishing technique that emulates a file archiver software in the browser while using a .zip domain.

Introduction

Last week Google released several new top-level domains (TLDs) including .dad, .phd, .mov and .zip. Many members of the security community began posting about concerns they had with TLDs that can be mistaken for file extensions, specifically, .mov and .zip. The intention of this article isn’t to discuss my opinion on the topic, instead, I’ll be showcasing how it can be used to enhance phishing engagements.

With this phishing attack, you simulate a file archiver software (e.g. WinRAR) in the browser and use a .zip domain to make it appear more legitimate.

Documenting the rise of facial recognition in the UK

Facial recognition surveillance turns us into walking ID cards, and treats members of the public like suspects in a high-tech police line up.

Our new detailed report, Biometric Britain: The Expansion of Facial Recognition Surveillance, lays out how police, retailers, tech companies and even some schools are investing huge sums of money into this intrusive technology.

When Hackers hack the Hackers - Malware Analysis for a group targeting Malware Developers

Last year, our experts had the opportunity to observe the execution of non-standard processes in a sandbox-like, isolated virtual machine (VM). Further analysis of these processes revealed Command & Control (C2) connections using Discord for communication. As we continued to analyse the C2 agent, we also gained access to the attacker's Discord channel and were able to take a look at all the commands and modules executed for many more compromised systems.

This attacker/group was very different to the ones we typically see while doing Incident Response for our customers in terms of the motivation and goals. It seemed, that this attacker was mainly compromising Malware developers and or Offensive Security related people to steal and sell code from the target systems. In this post, the malware analysis process, as well as attacker activities and Indicators of Compromise (IoCs) are presented.

From “Heavy Purchasers” of Pregnancy Tests to the Depression-Prone: We Found 650,000 Ways Advertisers Label You

A spreadsheet on ad platform Xandr’s website revealed a massive collection of “audience segments” used to target consumers based on highly specific, sometimes intimate information and inferences

What words would you use to describe yourself? You might say you’re a dog owner, a parent, that you like Taylor Swift, or that you’re into knitting. If you feel like sharing, you might say you have a sunny personality or that you follow a certain religion.

LLMs are good at playing you

Large language models (LLMs) are eerily human-like: in casual conversations, they mimic humans with near-perfect fidelity. Their language capabilities hold promise for some fields — and spell trouble for others. But above all, the models’ apparent intellect makes us ponder the fate of humanity. I don’t know what the future holds, but I think it helps to understand how often the models simply mess with our heads.

Recall that early LLMs were highly malleable: that is, they would go with the flow of your prompt, with no personal opinions and no objective concept of truth, ethics, or reality. With a gentle nudge, a troll could make them spew out incoherent pseudoscientific babble — or cheerfully advocate for genocide. They had amazing linguistic capabilities, but they were just quirky tools.

US government agencies hit in global cyberattack

Several US federal government agencies have been hit in a global cyberattack by Russian cybercriminals that exploits a vulnerability in widely used software, according to a top US cybersecurity agency.

The US Cybersecurity and Infrastructure Security Agency “is providing support to several federal agencies that have experienced intrusions affecting their MOVEit applications,” Eric Goldstein, the agency’s executive assistant director for cybersecurity, said in a statement on Thursday to CNN, referring to the software impacted. “We are working urgently to understand impacts and ensure timely remediation.”

Mozilla puts advertising into Firefox AGAIN

They have added a new option to Firefox privacy settings, enabled by default of course, to allow "suggestions from sponsors" to "occasional"ly appear in the navigation bar dropdown, as if they were bookmarks. I noticed this by seeing a link to Office Depot in the pulldown, wondering what Office Depot page I had bookmarked or in my history, and discovering that it was an in-browser "sponsored suggestion". It appears to work by sending all your navigation bar typeahead to Mozilla so it can match you with a sponsor (oops about that privacy, lol). I'm not sure how recent this "feature" is, but I think it is recent, and I only noticed it today (I'm on LTS Firefox but installed an update a few days ago). Maybe the less stable releases have had it for longer.

Turning the sponsored suggestions off is not that difficult (see the url above for instructions), but Mozilla's unceasing obsession with inveigling advertising into the browser is... disturbing. Another day in the enshittification of the web.

Sharing Your Credit Card With a Shady Pirate IPTV Service Isn’t a Brilliant Idea

Pirate IPTV services have transformed into a billion-dollar industry in recent years. It is a highly profitable business that, at the upper echelon, appears to be well organized. However, research from the Digital Citizens Alliance shows that handing over credit card details to unknown parties also has its drawbacks, including 'surprise' charges.

Cracking Down on Dissent, Russia Seeds a Surveillance Supply Chain

Russia is incubating a cottage industry of new digital surveillance tools to suppress domestic opposition to the war in Ukraine. The tech may also be sold overseas.

As the war in Ukraine unfolded last year, Russia’s best digital spies turned to new tools to fight an enemy on another front: those inside its own borders who opposed the war.

To aid an internal crackdown, Russian authorities had amassed an arsenal of technologies to track the online lives of citizens. After it invaded Ukraine, its demand grew for more surveillance tools. That helped stoke a cottage industry of tech contractors, which built products that have become a powerful — and novel — means of digital surveillance.

The technologies have given the police and Russia’s Federal Security Service, better known as the F.S.B., access to a buffet of snooping capabilities focused on the day-to-day use of phones and websites. The tools offer ways to track certain kinds of activity on encrypted apps like WhatsApp and Signal, monitor the locations of phones, identify anonymous social media users and break into people’s accounts, according to documents from Russian surveillance providers obtained by The New York Times, as well as security experts, digital activists and a person involved with the country’s digital surveillance operations.

Surveillance advertising in Europe: The adtech industry tracks most of what you do on the Internet. This file shows just how much

The advertising industry has more than 650,000 labels to target people. Reading through them reveals how even the most sensitive aspects of our life are monitored. EU-based data brokers play a vital role in this system.

Everything we do on the Internet is being recorded and analyzed in order to achieve one goal: to show us targeted advertising. This is a reality to which many people have become accustomed in exchange for free services. However, very few people understand exactly where our data ends up when we visit websites, use apps or make digital payments. Targeted advertising moves in mysterious ways. That’s another fact we’ve become accustomed to.

Debunking Runa Sandvik — CatalanGate Spyware

In April 2022, the world was informed about 65 suspected instances of espionage in Catalonia. The revelation came through a report and data jointly released by The Citizen Lab, a public policy institution at The University of Toronto, and Amnesty Tech, a cybersecurity division of Amnesty International. Following their investigation, these special interest groups leveled direct accusations against the Spanish government, alleging the utilization of surveillance technology developed by Israeli cyber intelligence firms NSO Group and Candiru, LTD to target Catalan civil society.
