How can security teams effectively monitor evolving attacks and stay ahead of constantly shifting attacker infrastructure? We spoke with a chief information security officer at a transport company about how they use subscriptions to Search Updates in Threat Intelligence Lookup to tackle this challenge.
Here’s what we learned.
Company Info
Without getting into any specifics, our company operates in the transportation sector, managing logistics across North America, Latin America, and Europe. Right now, the IT security team is at 30 professionals and as the CISO I’m responsible for overseeing strategic planning, risk management, and operations. Speaking of our use of ANY.RUN’s products, currently we have licenses for both the Interactive Sandbox and TI Lookup.
TI Lookup from ANY.RUN provides a searchable database of over 40 types of indicators of compromise, attack, and behavior. The new data is extracted from thousands of public malware and phishing samples analyzed in ANY.RUN’s Interactive Sandbox every day.
Since all threats are executed in virtual machines, ANY.RUN takes a comprehensive snapshot of activities recorded during analysis, from network traffic file and paths to registry modifications and mutexes.
Key Security Challenges Faced
I’d say the entire transportation industry rests on email correspondence. Our company, despite being no match to giants like DHL, still has thousands of clients, contractors, and suppliers that we need to communicate with daily. Naturally, even a small email security slip-up, like exposing a few messages, could create major problems across the board. And attackers know this, too.
That’s why we pour a good chunk of the team’s resources into threat hunting and ensuring we have a grasp of the current threat landscape. We’re constantly monitoring for the recent attacks, phishing scams, malware campaigns, new CVEs, anything that may somehow be of concern to us. Of course, we can’t gobble up intel on every single threat out there, so we narrow it down to what’s relevant for our industry, and some of the core clients’ industries.
Where TI Lookup Fits in the Threat Hunting Strategy
Like any good security setup, we break ours down into areas. TI Lookup adds value pretty much evenly across all of them, from checking indicators as part of triage to discovering threat context in incident response.
Yet, if we’re talking about threat hunting, we subscribe to Search Updates in TI Lookup to keep up with the changes in ongoing cyber attacks and automate the collection of new indicators of compromise (IOCs) and threat samples. Let me explain how it works.
TI Lookup users can subscribe to custom search queries to receive timely updates on relevant Indicators of Compromise (IOCs), Indicators of Attack (IOAs), and Indicators of Behavior (IOBs) belonging to the threats of their interest.
Our threat hunting team is tasked with:
- Monitoring the current threat landscape
- Gathering data on the threats that are relevant to us
- Converting the data into actionable signatures and detection rules
There are several sources for such data, with publicly available research and reports published by other companies being the most common one. The problem here is that attackers constantly shift infrastructure – C2 servers might cycle IPs every 48 hours. So, relying on the indicators we find in public reports can do only so much. And that is precisely the detection gap that Search Updates in TI Lookup help to bridge.
Subscribing to Search Updates in TI Lookup allows us to use more stable indicators of behavior (IOBs) to track all the latest changes in specific attacks and see if they are still ongoing. IOBs are things like the tools used by attackers, the kill chain techniques, and infection traces on the system such as created directories, file names and types, etc. The things that do not tend to expire as fast as short-lived network infrastructure of attackers or hashes.
Essentially, with TI Lookup, we can put several IOBs related to a single attack together and use them in a search query to get notified about the latest samples and IOCs, which the threat hunting team can process and turn into detection rules.
The result is that we can follow active threats that may potentially target our company almost in real time because TI Lookup is updated every few hours with fresh data.
Some of the Use Cases for Search Updates
Our current collection of query subscriptions is well beyond a hundred entries. I will try to give you a few general types of threats that we tend to add to it and some of the examples.
At the moment we subscribe to well over a hundred search queries. To give you an idea of what we monitor, I’ll give you a couple of common threats we tend to follow.
Geo-Targeted Threats
While our HQ is in the United States, we have several local offices, which also become extensively targeted with cyber attacks. Search Updates make it easier for us to track several types of threats occurring in a specific country.
For example, we make sure to check for new samples of email-distributed infostealers in Colombia:
submissionCountry:”co” AND threatName:”stealer” AND filePath:”.eml” OR filePath:”.msg”
For this query, we get several updates almost every week.
We check the new samples and see if they have anything of value and if so, use the indicators extracted by the sandbox to make signatures to scan the company’s infrastructure for any matching threats.
Common Vulnerabilities and Exposures (CVEs)
Another top concern on any threat hunters’ list is CVEs, both old and new. One of the recent examples is CVE-2025-21298, the vulnerability where simply previewing a malicious .rtf document in Outlook leads to remote code execution and system compromise.
As soon as we learned about it, we made sure to go to TI Lookup and sign up for a query that would provide us with relevant samples in case any attackers decided to abuse this vulnerability.
In the query, we combined the file type (rtf) with Outlook, used the attc-doc (document attachment) tag, and excluded pdfs:
As a result, we now can minimize the manual research on this threat and in case an actual attack with this CVE is uploaded to TI Lookup, we’ll be notified about it.
Another thing that I think is worth mentioning here is that this CVE is a great example of how flexible TI Lookup can be. Despite not having a specific tag for this threat, we were able to make up for that by using the big selection of search parameters.
Credential-Theft Attacks
Given phishing is by far the top threat our company faces, one of the most common types of it is fake credential-stealing forms.
There is a campaign that has been going for a while, where attackers send emails that contain links to fake Microsoft 365 pages. The catch is that the malicious domain names are designed to masquerade as legit Microsoft ones. One of the standout things here is the use of “0” and “o” before “365”. Needless to say, the Search Updates feature does a great job letting us know about the new domains and actual examples of these attacks.
domainName:”o365.” OR domainName:”.o365″ OR domainName:”0365.” OR domainName:”.0365″
The team collects new domains and email samples and improves detection of any possible phishing attempts against our own infrastructure.

Search Updates Hacks
The thing that’s not related to Query Subscriptions per se but is still of huge help is the wildcards. It really adds flexibility to the searches, so we potentially set up queries to be more specific and general, depending on the indicators we use for a threat.
Just last week, we subscribed to a query for a new campaign where attackers use website addresses that start with “google.com” but then have random strings of characters afterwards.
To get the newest variants of these domains, we added the “?” wildcard to the query – which stands for any single character. We used four question marks to account for the random part of the domain.
Search Updates let us know every time a matching fake domain is added to TI Lookup’s database.
Impact on Security
In terms of company’s security, TI Lookup provides us with some of the latest threat intelligence we can get. We can apply it immediately while indicators are still active to identify threats and protect the organization’s infrastructure in advance.
It also improves our awareness of the threat landscape, letting us track a wider array of attacks. We now have more data on a broader pool of threats than ever before and can identify the ones that are still ongoing and those that are no longer active.
Impact on Operations
If we’re talking about the team’s performance, the productivity definitely went up after we began using Query Subscriptions. Back in the day, we had to allocate a lot of time and staff to follow up on attacks that were relevant to us. This was a lot of manual work. I’m not saying that we no longer do it, but receiving Search Updates definitely made the process much easier.
We now get automated updates and can actually focus on more threats than before, because we no longer need to rely on guesswork in deciding which attacks will be more likely to affect us.
Now we simply create a query and hit subscribe. The more new results we see arriving for a particular threat in TI Lookup the higher priority it gets.
Team Feedback
Most of the team are well-familiar with the ANY.RUN sandbox, so adopting TI Lookup felt natural for them. It is with some of the new folks on the team we had to work a little harder to get them to a place where they could comfortably use the service. They mostly struggled with the query parameters and their meanings, as well as tags in the sandbox, which are the same in TI Lookup. But most of them managed to become fairly proficient in a week or two.
