hacking: security in practice
Industry standards - Companies giving access to sensitive personal data (contracts, photos) from publicly accessible URLs

I've recently come across the same issue twice, with major companies, so probably it has become a mainstream policy:

The first one, a multinational telco. I agreed to a new contract, which was published on a public URL for me to check and sign. The contract (which included my social security number, ID number, full name, date of birth, etc) was there for about a month; it was removed after I protested. I can't tell for how long it would be there.

The second one, an international enterprise: After I asked for my data stored on their systems (they give you the option, no special request) they send me a public URL also. It included my ID photos. They were there for 3 months, according to their policy. As an international company, they were much more cumbersome (rather unwilling) to remove them before the time their policy dictates; to be honest, I doubt if I spoke to any human being, probably they were all bots. I can't tell if my ID photos where publicly available after I asked my data or from the day I signed in.

Both companies answer was on the same basis: It's a URL which is not searchable (no results for these kind of URLs from internet search engines) so since I'm the only one who has it, I'm the only one capable of accessing it.
I consider this to NOT be secure. Like having something valuable on a public road, but it's a small road that no-one passes by; most probably, but not 100%, it won't be stolen.

So my questions for anybody in the IT security or audit industry,
- how is it possible for this policy to be acceptable from major companies? - Can it really be considered safe, a public URL; just because it's long, no results returned from search engines, and send only to one person? Send by non-encrypted e-mail, so even if the rest of the chain would be secure, it could be breached through mail. - If a malicious person (cracker, black hat hacker, whatever the terminology) or just a curious and very lucky person who tries many different URLs, access these data: Is there any way to persecute him/her? He did nothing unlawful, He just opened a public URL.

My question to hackers, have you managed to access such personal data on enterprises URLs? Is it really tough to traverse their sites to locate them?

New malware dropper called NullMixer infects Windows machines

New malware dropper called NullMixer infects Windows machinesPost Views: 5 Premium Contenthttps://www.blackhatethicalhacking.com/wp-content/uploads/2022/08/Patreon-1.png Subscribe to Patreon to watch this episode.
Reading Time: 3 Minutes A new malware dropper named ‘NullMixer’ is infecting Windows devices with a dozen different malware families simultaneously through fake software cracks promoted on malicious sites in Google Search results.

NullMixer acts as an infection funnel, using a single Windows executable to launch a dozen different malware families, leading to over two dozen infections running a single device.

These infections range from password-stealing trojans, backdoors, spyware, bankers, fake Windows system cleaners, clipboard hijackers, cryptocurrency miners, and even further malware loaders.

To distribute the malware, the malware distributors use ‘black hat SEO’ to display websites promoting the fake game cracks and pirated software activators in high search result positions on Google.

BleepingComputer tested a Google search for ‘software crack,’ and many of the sites said to be distributing this malware, as shown below, were listed in our search results in the second, third, and fourth search result positions.

Launching dozens of malwareNullMixer is commonly downloaded as files named similarly to ‘win-setup-i864.exe,’ that when launched, create a new file called ‘setup_installer.exe.’

This new file is responsible for dropping dozens of malware families and, having done that, launches another executable, ‘setup_install.exe.’

That third file launches all malware dropped in the compromised machine using a hardcoded list of their names and the Windows’ cmd.exe’ tool.

ndancy.

Whatever the case, it would be practically impossible for all those malware families to run on a breached computer and not generate abundant symptoms of compromise for the victim to realize the infection.

These symptoms could include heavy hard disk activity, increased CPU and memory utilization, unusual windows opening for no reason, or simply a noticeable performance issue on the infected device.

Thus, NullMixer is less of a stealthy threat now and more of a catastrophic encounter that can likely only be resolved through a reinstall of Windows.

Users must always consider the risks of downloading executables from obscure online sources and avoid resorting to software piracy.

Self Hosted Proxy Service

We have created a proxy software that can be deployed to any server and will convert it into a proxy server. So here's how it works.

Let's say you have a server with IP 192.xxx.xxx.023.

We will deploy our software to your server on port let's say:8899

Now Your proxy server is up and running on 192.xxx.xxx.023:8899

To use the proxy simply pass the website in the URL like: -

http://192.xxx.xxx.023:8899/url=https://www.example.com



It will work seamlessly like any other proxy service e.g. ScrapingAPI, etc



Features:

1. Both residential/data center IPs to choose from.

2. Low pricing

3. Geolocation according to your requirement.

4. Decentralized nodes.



For more info please contact me.

My Apartment building is switching encryption protocol

Hello,

I live in student accommodation. Me and some engineers clone RFID cards to create replicas for anyone who wants one. This is so people can leave one in their door and take one with them or if you lose one you still have a spare etc...

Protocol was MIFARE CLASSIC 48 bit, easy to crack with Cipher. They are switching to MIFARE PLUS 128 bit, not so easy. The company that provides this is ONITY. We understand we may have been the ones to cause this change.

Any suggestions to cut corners on cracking the encryption or are we stuffed?

20 digit numerical Wordlist

My router has a default wifi password of 20 numerical digits. After attempts to build a wordlist containing at least some of the permutations i failed really hard (what is exactly the intention behind such a huge password).

What I've done so far:

1. start at 000... add one, save (simplyfied)
2. when starting the script again, check for the last number and continue from there



A few problems i aknowledged:

1. it takes for ever (I know thats supposed to be) and I can't imagine a way of shortening the list eg start at 01111.. but then cases like 0XXX...0...XXX are excluded (and checking for three same digits in a row would only slow it down even more)
2. the txt file i wrote everything into is getting EXRTREMELY HUGE: at 5*10^9 its 110GB (expected but can't find a way to fix this)

Im not asking for tech support, just wanting to collect some ideas.

Thank you in advance!
