That was me, and I'm gonna stand by that with skill its not impossible to catch using things like timing and sizes and such signals, I worked with people who built tools for this kind of stuff (and sold them to lovely human being :smith:) and I hosed a lot of lovely tor stealth projects that tried to mask as other things.

Hey sec fuckup thread! I know I've seen some awesome posts about what cipher suites should be enabled...does anyone have a config or can link to an ideal nginx SSL config? Specifically for ssl_protocols and ssl_ciphers?

check out sslscan which does most of the things ssl labs does but you can run it locally.


yeah i think that's where i originally got mine from, then i massaged it until i was happy. here's mine if anyone cares:

code:
ssl_prefer_server_ciphers on;
ssl_protocols             TLSv1 TLSv1.1 TLSv1.2;
ssl_ciphers               "EECDH+ECDSA+AESGCM EECDH+aRSA+AESGCM EECDH+ECDSA+AESGCM EECDH+aRSA+AESGCM EECDH+ECDSA+SHA384 EECDH+ECDSA+SHA256 EECDH+aRSA+SHA384 EECDH+aRSA+SHA256 EECDH EDH+aRSA !RC4 !aNULL !eNULL !LOW !3DES !MD5 !EXP !PSK !SRP !DSS";
other useful settings you should read up about and probably use are:

- ssl_dhparam
- ssl_session_*
- ssl_stapling

also if you're a cool ssl bro and are 100% sure you'll only use SSL forever you wanna do:

code:
add_header                Strict-Transport-Security "max-age=15768000; includeSubdomains;";

Yeah I janitored my own bespoke artisanal cipher suite, but the mozilla one is a very good starting point and you wouldn't be bad off at all if you left it.

you can use ssh-keygen -lf ~/.ssh/authorized_keys or known_hosts to dump the hashes. use the -E md5 switch if u need md5

at some point he removed support for a deprecated protocol thing that a significant portion of the servers still needed. His answer was "The servers should just follow spec". He could have just made a configuration option, but no.

An acquaintance of mine took a sabattical and scanned the internet for unsecured mongos for 15 hrs a day for a year. He found thousands and did hundreds of disclosures to whomever owned the databases. About half were fixed I think.

I'm not 100% sure but still fairly certain he would have found the same db and disclosed it to the owners.

just my luck, I get out of kitty jail just in time for the thread to be disappeared <:mad:>

italy is currently being rocked by a bizarre scandal of the cyber persuasion. the occhionero siblings, entrepreneurs in the finance sector, freemasons and by all accounts smart people (he's a nuclear engineer, she's a chemistry phd), are found to be conducting a multi-year spearfishing campaign against politicians, entrepreneurs and... other freemasons. their spyware appears to have been entirely developed in-house, and it's been active since at least 2011. kaspersky describes it as "amateurish" but I've gotten my hands on a recent sample and it appears to have been developed by someone who, if not a cybercriminal, has at least an idea of how malware analysis is done and how to slow it down. well, at least the anti-analysis protection and obfuscation was, and I know it's not a commercial framework because the few unobfuscated strings are unique to the malware

on the other hand, the occhionero siblings made huge, gigantic opsec blunders, and I argue that they had outside help with the malware development, because they clearly aren't serious criminals. consider the strongest piece of evidence against them: the malware exfiltrates data by sending e-mails and uses a commercial component to do so, which requires a license code to unlock. not only the malware contains said license code, but italian police asked the fbi for help, the fbi obtained the name of the licensee, and it was the occhionero brother: the guy had virtually embedded his real name in his phishing malware

on the other other hand, when the police came to arrest them, the brother rebooted the bitlocker-encrypted computer and now refuses to provide the password, while the sister locked her smartcard by entering the wrong pin several times. it's not going to help them much because the amount of evidence against them is impressive: they didn't just embed personally identifying information in the malware, they also hosted the c&c server on their company's website, and they talked about their dirty business on regular cleartext phone calls, that the police duly wiretapped

all considered, the campaign wasn't terribly successful. of about 18000 targets, only about 10% are estimated to have been compromised

the motive is still a mystery. insider trading seems to be the current consensus

the malware samples I've seen raise some extremely obvious red flags when run in the simplest of the automated analysis tools, and they're clearly part of a shared lineage dating back years, so it's a little amazing to me that it took so long for it to be noticed

:wow:

Great stuff! Keep us posted because I haven't seen this pop up in the infosec media anywhere yet.

Cool post, and keep us updated. This seems bizarrely inept.

I'm just wondering what the significance of being a freemason and targeting freemasons was. Is freemasonry different in Italy compared to the US? In my area they seem to be guys who hang out once a week and help sponsor kids/families to the Shriner's hospital. Honestly, they seem like Elks with less pancake breakfasts.

Well, from what I've heard freemasons in the US are fairly benign but it Europe they are more like an old boys network where elites meet to do backhanded deals and politics or w/e idk. Much more elite and secretive in any case. I suppose not much more sinister than any exclusive club like a country club or something but you get the idea.

Now, in Italy there was a big scandal about a lodge called Propaganda Due where a lot of rich and powerful were members. The lodge was far right and actively undermining the state by ordering assassinations and causing banks to collapse and whatnot. They basically wanted to overthrow the government. After a few scandals where they were implicated they got kicked out of the masons but kept operating independently. Finally in the 80's they were disbanded. Read the wikipedia page if you want to learn more.

Silvio Berlusconi was a member btw..

So yeah, Italy has some history with the masons.

I fixed my washing machine the other day. The magnetic inlet valve had failed. I temporarily rerouted the main wash water intake thru the pre wash until my $25 part came in, and replaced the part yesterday.

It was easy to diagnose and fix because it doesn't have a computer inside.

ok thanks for reading bye
