The current threat landscape continuously proves that the theory of evolution also applies to malware. The latest proof? IcedID, which went from being a run-of-the-mill banking trojan to a ransomware dropper.

More than 50 IP addresses and domains were publicly listed^{1, 2, 3, 4} as IcedID indicators of compromise (IoCs). WhoisXML API researchers subjected them to a DNS intelligence analysis to uncover more connected artifacts, including:

Examining WoofLocker under the DNS Lens

As far as scams go, WoofLocker has probably proven that staying in the game is possible with continuous improvement. The latest trick up its sleeve? The addition of traffic direction to ongoing schemes.¹

AlienVault OTX compiled 784 indicators of compromise (IoCs) over the course of WoofLocker’s eight years of operation.² Apart from identifying unreported connected artifacts, we at WhoisXML API also sought to determine if the threat actors employed various providers, maintained a well-dispersed infrastructure, and compromised sites other than those hosting adult content.

Decoy Dog, Too Sly to Leave DNS Traces?

Decoy Dog has gained renown for its ability to abuse the DNS to evade detection and consequent removal. Is it too sly, though, to leave even the tiniest traces behind?

Infoblox identified 23 Decoy Dog indicators of compromise (IoCs) comprising 11 domains and 12 IP addresses in an in-depth analysis report they published in April 2023.¹

Will Redis Remain on Threat Actors’ Radar?

The Mushtik Gang was the first threat group that took advantage of the Redis Lua Sandbox Escape and Remote Code Execution Vulnerability, also known as “CVE-2022-0543,” in March 2022.¹ Since then, many attackers² have exploited the bug to get to their intended targets.

P2PInfect, a self-replicating peer-to-peer (P2P) worm, is just the latest tool a threat group used. Seven indicators of compromise (IoCs) have been made public in July.³

To uncover yet-unidentified Redis attack-connected artifacts, WhoisXML API expanded the list of published IoCs aided by exhaustive DNS intelligence.

Finding WyrmSpy and DragonEgg Ties to APT41 in the DNS

It’s not unusual for threat groups to survive and even continue to thrive despite the capture and incarceration of some of their members, sometimes even leaders. APT41 can be considered proof of that.¹ 

Lookout researchers believe that APT41, responsible for tons of targeted attacks since at least 2012,² was recently spotted distributing two mobile spyware—WyrmSpy and DragonEgg—to further their cyber espionage activities. A total of 12 IoCs—five for WyrmSpy and seven for DragonEgg—have been made public and attributed to the APT group.

WhoisXML API sought to determine ties between APT41 and WyrmSpy and DragonEgg aided by comprehensive DNS intelligence. We also identified other artifacts that could be connected to the recently discovered mobile spying campaigns, including:

DNS Insights behind the JumpCloud Supply Chain Attack

To make the Internet safer and more transparent, WhoisXML API took a closer look at the JumpCloud supply chain attack IoCs via a DNS deep dive and identified more artifacts, namely:

AI Tool Popularity: An Opportunity for Launching Malicious Campaigns?

A Cybersecurity Collaboration between WhoisXML API and Bayse Intelligence.

An increasing number of organizations are reaping the benefits that AI tools offer. Despite improving employee productivity, however, 78% of users are afraid that threat actors could exploit the solutions to defraud them.¹ The widening range of attacks targeting tools like ChatGPT² and Grammarly,³ unfortunately, isn’t assuaging their fears. 

To help out, WhoisXML API and Bayse Intelligence teamed up to identify web properties that attackers could have already used, are currently using, or may weaponize in the future to target eight of 2023’s best AI productivity tools.⁴

Our collaborative effort led to these findings:

Signs of MuddyWater Developments Found in the DNS

MuddyWater has been launching politically motivated targeted attacks since 2012. Despite its age, though, the threat actors aren’t showing any sign of retiring anytime soon.

Reports say MuddyWater recently updated its C&C framework with PhonyC2’s launch¹ in an attempt to better control their hold on target networks. That’s not all, they also partnered with DEV-1084² in hopes of keeping their APT involvement a secret from intended victims.

Deep Instinct named 39 PhonyC2 IoCs in their analysis. Microsoft, meanwhile, published 14 IoCs related to the MuddyWater-DEV-1084 partnership.

To uncover yet-unidentified connected artifacts, WhoisXML API researchers dove deeper into the threats aided by our comprehensive DNS intelligence and found:

DNS Revelations on Eevilcorp

They say, “Art imitates life,” but the opposite can also be true when it comes to cybercrime. And no threat group could be a better example than Eevilcorp¹—a real-life counterpart of the “Mr. Robot” antagonist E Corp.

Nine domains have been publicized as Eevilcorp attack IoCs. To uncover more connected artifacts, the WhoisXML API research team dove deep into the threat aided by comprehensive DNS intelligence. Our in-depth analysis revealed:

A DNS Deep Dive into Malware Crypting

These days, it has become common practice for threat actors to employ malware crypting to better evade detection and consequent blocking. And that has made AceCryptor a must-have, it seems, for cyber attackers.¹

The ubiquity of malware crypting has also sparked a clamor among several cybersecurity community members to push for a clampdown on the service.²

To uncover yet-unidentified more connected artifacts in our bid to make the Internet safer, WhoisXML API expanded lists of IoCs connected to malware crypting services in general³ and AceCryptor⁴ aided by our extensive DNS intelligence.

Our in-depth analysis led to the discovery of:

BlackCat Hacks Reddit Again, Take a Look at What the DNS Revealed

The BlackCat ransomware gang first trailed their sights on Reddit last February.¹ They were able to steal user data by phishing an employee. They weren’t done, though, as they again hacked the sharing platform’s network, managing to lock employees out of their systems and threatening to leak the stolen data should the company fail to pay the ransom.

A total of 13 IP addresses were identified as indicators of compromise (IoCs) related to the ransomware.²

To uncover yet-unidentified connected artifacts as part of our ultimate goal—to make the Internet safer and more transparent—WhoisXML API trooped to the DNS and found:

MOVEit Exploit-CLOP Ransomware Threat Vector Identification Aided by DNS Intelligence

Several threat actor groups have joined in on exploiting the zero-day MOVEit vulnerability to launch their own brands of mayhem—and the CLOP ransomware group is just one of them.¹ The MOVEit vulnerability gave the CLOP ransomware operators access to connected databases, enabling them to infer information about their structure and content.

A total of 139 indicators of compromise (IoCs) related to the MOVEit-enabled CLOP ransomware attacks have been made public since the start of June.

To uncover yet-unidentified more connected artifacts, we at WhoisXML API dove deep into the threat aided by our comprehensive DNS intelligence.
