Shining the WHOIS and DNS Spotlight on International Fraud

Scammers and fraudsters have been making life hard for users the world over for a long time now. To help expose potential malicious campaigns, threat researchers like Dancho Danchev have been collating indicators of compromise (IoCs) that can be used in further investigations.

Gauging the Scale of an Active Ransomware Gang’s Infrastructure

Ransomware gangs are now a dime a dozen. But in reality, victims rarely engage directly with their members. They are, in fact, more likely communicating with what the cybersecurity community has dubbed "ransomware affiliates" who earn as much as 75% of the ransom payment.

Beyond Healthcare IoCs: Threat Expansion and EHR Impersonation Detection

The healthcare industry has had a rough couple of years since the COVID-19 pandemic started. But this didn't stop threat actors from attacking the sector, with several healthcare organizations targeted by ransomware, data breach, and other cyber attacks.

Detecting ChatGPT Phishing on Social Media with the Help of DNS Intelligence

Since its launch last November, the ChatGPT hype has only increased not only among users but also abusers. Cyble researchers recently spotted phishing attacks using supposed ChatGPT sites to phish for personally identifiable information (PII), specifically credit card data.

Detecting Malware Disguised as OneNote with Threat Intelligence

We've seen threat actors abuse almost all Windows OS applications in their campaigns, disguising malware as macros, Word documents, Excel spreadsheets, and PowerPoint presentations to trick users into opening and executing them.

Detecting Carder-Friendly Forums through IoC Expansion

Carding or the theft and consequent selling of credit and other payment card information to users has long been a problem. And with the ease of obtaining hosts for carder forums and communities and hiding their tracks online, the threat has become even bigger.

SocGholish IoCs and Artifacts: Tricking Users to Download Malware

As all initial-access threats go, SocGholish is among the trickiest. It often comes disguised as software updates, deceiving victims into downloading a malicious payload that could eventually lead to more lethal cyber attacks. In fact, researchers at ReliaQuest found evidence that an initial SocGholish malware distribution was intended to deploy ransomware.

Profiling a Massive Portfolio of Domains Involved in Ransomware Campaigns

Security researcher Dancho Danchev discovered a portfolio of domains and IP addresses used by known threat actors in ransomware campaigns. The said portfolio consists of 62,763 domain names and 810 IP addresses. We analyzed a sample of these malicious properties using TIP and found that:

The Fight Against Hive Ransomware May Not Be Done as Yet-Unidentified Artifacts Show

The Hive Ransomware Group has had more than 1,500 victims across more than 80 countries worldwide. They attacked hospitals, school districts, financial firms, and critical infrastructure until the U.S. Department of Justice (DOJ) disrupted their operations. Have we seen the fall of the group's entire infrastructure?

Gauging How Big a Threat Gigabud RAT Is Through an IoC List Expansion Analysis

Targeting governments the world over in cyber attacks is not a novel concept. Doing that using mobile apps, however, is quite new as a tactic. And that's what Cyble researchers reported as Gigabud RAT's modus operandi - trailing its sights on citizens of Thailand, the Philippines, and Peru who use government-owned institutions' mobile apps.
