New COLDRIVER ClickFix Campaign Uses BAITSWITCH, SIMPLEFIX

🔍 Zscaler details a new COLDRIVER ClickFix campaign that deploys two lightweight families: BAITSWITCH, a DLL downloader, and SIMPLEFIX, a PowerShell backdoor. Victims are lured to execute a malicious DLL via a fake CAPTCHA; BAITSWITCH fetches SIMPLEFIX while presenting a Google Drive decoy. The chain stores encrypted payloads in the Windows Registry, uses a PowerShell stager, and clears the Run dialog to erase traces. Zscaler notes the campaign targets NGOs, human-rights defenders, think tanks, and exiles connected to Russia.

Zscaler ThreatLabz: Global Ransomware Surge 2024–2025

🔒 Zscaler's annual ThreatLabz Ransomware Report (April 2024–April 2025) warns of a marked rise in extortion-focused attacks: incidents increased 146% year-over-year while exfiltrated data grew 92%. The vendor attributes this to a strategic shift from pure encryption to data theft and public shaming, with criminals using stolen files as leverage. Researchers also report that generative AI is increasingly incorporated into attackers' playbooks to enable more targeted and efficient campaigns. The U.S. accounted for half of all recorded attacks, Germany saw a nearly 75% rise and is the EU's most affected country, and the most-targeted sectors were manufacturing, technology and healthcare.

CRM Supply-Chain Breach via Salesloft Drift Impacts Vendors

🔒 Palo Alto Networks, Zscaler and Cloudflare disclosed a supply-chain breach traced to the Salesloft Drift integration with Salesforce. The compromise exposed business contact information, account/contact/case/opportunity records and, in some instances, OAuth tokens and plaintext support-case content; attachments and files were reportedly not affected. Palo Alto's Unit 42 observed active searches of exfiltrated data and deletion of queries consistent with anti-forensics. Vendors are advising immediate token revocation, credential rotation and comprehensive review of Salesforce logs and SOQL query history.

Supply-chain Breach Impacts Palo Alto, Zscaler, Cloudflare
