📢I recently investigated a campaign targeting the cryptocurrency industry. I wrote a detailed report that includes TTP, IOC and more. Here is a thread about this attack! 🧵👇

@MsftSecIntel @MicrosoftAU #infosec #cryptocurrency #threatintelligence #apt

microsoft.com/en-us/security…

The attack started on Telegram to identify the targets, then they deployed a weaponized Excel document which finally delivered the final backdoor through multiple mechanisms. ☠☠️ #infosec #malware #backdoor

🧐To identify the targets, the threat actor sought out members of cryptocurrency investment groups on Telegram.

👀They created fake profiles using details from employees of the company OKX. #infosec #Cryptocurency

For those who do #ThreatIntel; could you please read this thread and share with me your thoughts?

1. Client signs up for a service
2. Client after a while sends email requesting their email to be deleted from our systems to limit online exposure
3. Client gets email deleted

1/3

After a month+
1. Clients signs up for service again using different email
2. After a while, client sends an email requesting account deletion claiming they're limiting their online exposure

Question after this scenario: what is the real benefit they gain from this? #OSINT

2/3

You might be asking how I noticed this? The answer is they used the exact same email! It was very clear to me that I've seen this before & a quick search revealed that my brain was still functioning! 😊

I would appreciate anyone educating me with ideas! #ThreatIntel #OSINT

It is done! This should have been released a long time ago but I am glad I took the time to finish it.

For those of you who are into #osint or for #threatintel I am releasing my OSINT Notebook to share with you all.

github.com/tjnull/TJ-OSIN…

This notebook provides an overview of the tools, techniques, and resources that I use for a variety of situations for performing reconnaissance and OSINT operations. This Notebook has helped me in many situations to learn more about OSINT.

If you do not use Joplin I have provided raw markdown files that you can use to integrate into the note taking tool that you use.

#ICYMI, here's a #threatintel related🧵👇 by me on @USTreasury advisory on DPRK IT workers' attempts to obtain employment while posing as non-North Korean nationals: home.treasury.gov/system/files/1… (1/?)

DPRK IT workers "engage in a wide range of IT dev work, such as: mobile & web-based apps, virtual currency exchange platforms & digital coins. Some
designed virtual currency exchanges or created analytic tools/apps for virtual currency traders & marketed their products." (2/?)

This reminds me, for example, of Marine Chain Token: (justice.gov/opa/pr/three-n…; justice.gov/opa/press-rele…), #AppleJeus (cisa.gov/uscert/ncas/al…) and, more recently, #TraderTraitor (cisa.gov/uscert/ncas/al…). #HIDDENCOBRA/#APT38 loves loves loves their crypto (3/?)

@CYINT_dude

Many #threatintel teams likely have a new requirement to provide daily (or more!) updates on the UA/RU war to include cyber threat activity AND factors like sanctions, military developments, etc. This is not easy. Here are my ✅ tips for surviving "intel update fatigue" 🧵.

✅ Reduce, filter sources

There is too much information--much of it unconfirmed--from disparate sources. Stick to news from reliable and official sources (national CERTs, your intel providers, AP, Reuters, BBC, etc.) who have done the vetting for you.

✅ Change your dissemination habits; prioritize speed

If your team typically disseminates information via traditional reports (presumably over email), consider creating a dedicated chat channel with your security and business partners exclusively for fast updates...

My parents have been looking to buy an RV and this evening my Mom found an oddly cheap RV on an "RV Trader" website. I'm pretty sure it's a scam - come with me while I investigate and use some #OSINT along the way! #ThreatIntel #SCAM #infosec

The link my mom sent was for a 2005 Airstream Bambi, for 9,800 dollars - wait, that seems way too cheap!

First red flag, the website doesn't seem to give you any information....you need to click "request more info" which prompts for your contact information.

In light of the recent #SupplyChain attack on @KaseyaCorp by #REvil, it is worth paying attention to decoder[.]re included within the ransom notes, used additionally to 'mirror' in TOR network. #Ransomware #Cybersecurity #ThreatIntel #ThreatHunting #Malware

Similar to decryptor[.]cc and decryptor[.]top in previous #REvil/#Sodinokibi versions, decoder[.]re is used to grant the victims access to the threat actors WEB-site for further negotiations should their connection be limited via #TOR.

To access the page in WWW or TOR - the victim needs to provide a valid UID (e.g. "9343467A488841AC")

ICYMI, @PwC_UK’s 2020 #threatintel Year in Retrospect report is out now! All team contributed but h/t to @KystleM_Reid! :fire: You can check it out here: pwc.to/2ZPx7fo In this thread, I will summarise some of what I thought were key findings: 🧵👇 1/n

#Ransomware has become the most significant cyber security threat faced by organisations, irrespective of industry/location. TTPs have pivoted to mass data exfiltration prior to encryption, along with leaks & extortion. S/o to @andyp346 for all your work countering this.🙏 2/n

In 2020, 86% of the incidents that PwC’s Incident Response team responded to were attributable to cyber criminals. 79% of leaks happened in 2nd half of 2020. Our data sees Manufacturing, TMT, & Professional Services most impacted. 3/n

I'm generally a pretty positive person, but it's Festivus, so let's blow off some steam and air our #threatintel grievances. Threat intel feeds are just data feeds, they're not threat intel. Please stop naming groups after malware, it's confusing AF.

Nation states are not countries. CC @cnoanalysis en.wikipedia.org/wiki/Nation_st…

If you use fear, uncertainty, and doubt to sell things, you are a GRINCH and please stop.

A thread on bad analysis. When #ThreatIntel analysts want to show off their Foreign Policy and Economist subscription status after reading the Russian foreign policy Wikipedia page /n #threatintelligence #cybersecurity #infosec

Most analysts who are "doing attribution" aren't doing good cyber threat intelligence, they're doing poor foreign policy analysis

They neither have neither the data nor the expertise to make even a moderately confident statement on attribution

My paper on “Public Attribution of Cyber Intrusions” was published in the Journal of Cybersecurity (@OUPAcademic). It's open access so everyone can have a read. I summarize the main insights in the thread below:
academic.oup.com/cybersecurity/…

Drawing on the intelligence studies literature, I argue that public attribution is employed to shape the “rules of the game” and thereby shape the normative and operational environment for cyber operations.

I split attribution into sense-making and meaning-making processes: sense-making process refers to the knowledge-generation process that establishes what happened, the meaning-making process to deliberate actions that influence how others interpret a particular cyber intrusion

Sunday's fun fact on inferences:
Arthur Conan Doyle's fictional character "Sherlock Holmes" is based on his real-life professor under whom he studied medicine,Dr. Joseph Bell.

"It is most certainly to you that I owe Sherlock Holmes and though in the stories I have the advantage

...of being able to place Sherlock in all sorts of dramatic positions, I do not think his analytical work is in the least exaggeration of some effects which I have seen you produce in the outpatient ward"
wrote Conan Doyle in a letter to Dr. Bell.

Apparently, other than his medical education, Dr. Bell was also very knowledgeable in other areas such as geography and the cultures, the dialects, patterns of speech and behavior, the army, and more. He was also very observant.

False flag operations are very rare because they're risky and the blowback effects are bad. Interestingly, the risks increase the more "important" you are so the most powerful countries are less likely to conduct FF ops. /1 #infosec #cybersecurity #ThreatIntel

Traditional covert and clandestine operations are cheaper, less risky, and more likely to succeed than false flag ops. Importantly, not all attempts to redirect blame is a false flag but just considered standard covert ops. /2

False flags are also generally misunderstood and confused. For example, using Russian as an English speaker in malware is, by itself, not a false flag but rather just considered good covert practice. It doesn't attempt to place blame but just conceal the operators better. /3
