Infostealer malware increased in 2024, hackers used it to steal credentials, cryptocurrency and other personal data from millions of users. If you remember, I reported countless times The Infostealer incident called Lumma Get Android, Windows, and even iOS and Mac users.
A new cybersecurity report, along with hackers using Lumma and STEALC, Redline and other infosealers, underscored 4.3 million units in 2024, bringing an astounding 330 million compromised qualifications I'm doing it.
Security researchers are also observing 3.9 billion credentials shared in a list of credentials that appear to be procured from Infostealer logs.

Infosealer-related attacks on the 2024 increase
a Cybersecurity Report With its threat intelligence platform, Kera revealed a sharp rise in Infosturer malware in 2024. Researchers observed surprising trends in how stolen data was distributed. Large compilation of credentials, often referred to as “credentials,” was shared throughout the Cybercrime forum. These lists were sourced primarily from Infostealer logs and included details of billions of logins harvested from infected devices.
One of the most notable incidents related to Infostealer malware was a violation of cloud data storage provider Snowflake. In April 2024, the threat actor accessed the customer account using the stolen login credentials. Taking advantage of weak security practices such as the lack of multifactor authentication, attackers attempted to extract valuable data and later sell it in the underground market. The violations affected at least 165 companies.
What is Artificial Intelligence (AI)?
The Kela report highlights that hackers have deployed 4.3 million machines and compromised 330 million qualifications by Lumma, Stealc, Redline and other infostealers. Almost 40% of these infected machines included corporate systems credentials, such as content management platforms, email accounts, Active Directory Federation Services, and remote desktop environments. In total, this accounted for 1.7 million breach bots and 7.5 million stolen qualifications.
The report also found that 3.9 billion credentials are shared in a list of credentials that appear to be procured from Infostealer logs. Kela's analysis suggests that almost 65% of infected devices are personal computers that store corporate credentials, and are the main targets of Infostealer malware.

2025 is no different
Infostealer malware won't go anywhere in 2025. With Malware-as-aaaaaaaaaaaaaaaaaaaaaaaaaaaaas-aaaaaaaaaas-cybercriminals likely continue to use their qualifications as a go-to method to steal and gain access to the system.
But law enforcement is cracking down. In 2024, authorities were able to defeat a key part of the Infostealer ecosystem, including the disruption of Redline, one of the most widely used Infostealers. This showed that international organizations could chase not only malware developers but also the networks and underground markets that continue to maintain these businesses.
However, such takedowns rarely end the problem. Once one major info-sealer operation is closed, others will immediately step in instead. The constant demand for stolen credentials and the ability of cybercriminals to adapt means that infosealer attacks are likely to remain a major threat in 2025.
