ARMONK, N.Y., April 17, 2025 /PRNewswire/ -- IBM (NYSE: IBM) today released the 2025 X-Force Threat Intelligence Index highlighting that cybercriminals continued to pivot to stealthier tactics, with lower-profile credential theft spiking, while ransomware attacks on enterprises declined. IBM X-Force observed an 84% increase in emails delivering infostealers in 2024 compared to the prior year, a method threat actors relied heavily on to scale identity attacks.
The 2025 report tracks new and existing trends and attack patterns – pulling from incident response engagements, dark web and other threat intelligence sources.
Some key findings in the 2025 report include:
"Cybercriminals are most often breaking in without breaking anything – capitalizing on identity gaps overflowing from complex hybrid cloud environments that offer attackers multiple access points," said Mark Hughes, Global Managing Partner of Cybersecurity Services at IBM. "Businesses need to shift away from an ad-hoc prevention mindset and focus on proactive measures such as modernizing authentication management, plugging multi-factor authentication holes and conducting real-time threat hunting to uncover hidden threats before they expose sensitive data."
Patching Challenges Expose Critical Infrastructure Sectors to Sophisticated Threats
Reliance on legacy technology and slow patching cycles prove to be an enduring challenge for critical infrastructure organizations as cybercriminals exploited vulnerabilities in more than one-quarter of incidents that IBM X-Force responded to in this sector last year.
In reviewing the common vulnerabilities and exposures (CVEs) most mentioned on dark web forums, IBM X-Force found that four out of the top ten have been linked to sophisticated threat actor groups, including nation-state adversaries, escalating the risk of disruption, espionage and financial extortion. Exploit codes for these CVEs were openly traded on numerous forums —fueling a growing market for attacks against power grids, health networks and industrial systems. This sharing of information between financially motivated and nation-state adversaries highlights the increasing need for dark web monitoring to help inform patch management strategies and detect potential threats before they are exploited.
Automated Credential Theft Sparks Chain Reaction
In 2024, IBM X-Force observed an uptick in phishing emails delivering infostealers and early data for 2025 reveals an even greater increase of 180% compared to 2023. This upward trend fueling follow-on account takeovers may be attributed to attackers leveraging AI to create phishing emails at scale.
Credential phishing and infostealers have made identity attacks cheap, scalable and highly profitable for threat actors. Infostealers enable the quick exfiltration of data, reducing their time on target and leaving little forensic residue behind. In 2024, the top five infostealers alone had more than eight million advertisements on the dark web and each listing can contain hundreds of credentials. Threat actors are also selling adversary-in-the-middle (AITM) phishing kits and custom AITM attack services on the dark web to circumvent multi-factor authentication (MFA). The rampant availability of compromised credentials and MFA bypass methods indicates a high-demand economy for unauthorized access that shows no signs of slowing down.
Ransomware Operators Shift to Lower-Risk Models
While ransomware made up the largest share of malware cases in 2024 at 28%, IBM X-Force observed a reduction in ransomware incidents overall compared to the prior year, with identity attacks surging to fill the void.
International takedown efforts are pushing ransomware actors to restructure high-risk models towards more distributed, lower-risk operations. For example, IBM X-Force observed previously well-established malware families including ITG23 (aka Wizard Spider, Trickbot Group) and ITG26 (QakBot, Pikabot) to either completely shut down operations or turn to other malware, including the use of new and short-lived families, as cybercrime groups attempt to find replacements for the botnets that were taken down last year.
