Executive Summary

Threat actors continued to exchange ideas on how to maneuver within the economic and political constraints brought about by the conflict in Ukraine in Q2. Healthcare sector organizations faced a persistent threat from social engineering campaigns, with particularly increases in the use of fraudulent applications, fake Windows 11 upgrades, and employment-related scams to steal credentials and deploy trojans. The threat of vulnerability exploitation grew, averaging almost 70 Common Vulnerabilities and Exposures (CVEs) disclosed per day—up from 56 per day at the end of 2021. The pace of vulnerability disclosure likely represents a new normal. The threat from Initial Access Brokers (IABs) showed signs of resurgence, though this increase was not seen across all sectors. The threat from malware remained broadly consistent with previous quarters, underpinned by the high rate of new infostealers and trojans emerging and older versions launching new campaigns. Ransomware threat actors may be struggling to elicit payments from victims, driving changes to extortion tactics. While the ongoing war in Ukraine continued to be the primary driver of geopolitical risk, possible EU and NATO expansion—and new sanctions on Russia—will likely trigger Russia state-backed groups to target high-profile entities.

Key Findings

• Cybercriminals are concerned with challenges converting cryptocurrency to fiat currency.
• Social engineering campaigns increasingly used LNK shortcut files, fake Windows upgrades, and employment scams.
• The threat from CVEs and previously-unknown software vulnerabilities likely increased.
• The IAB marketplace showed signs of resurgence.
• The threat of malware was underpinned by the high rate of new infostealers and trojans emerging and older versions launching new campaigns used to conduct data breaches.
• There was a negligible change in the threat to most healthcare organizations from botnets, despite widespread media attention.
• The threat to healthcare sector organizations from ransomware and digital extortion likely increased. Eliciting payment from victims may be getting more difficult.
