AT&T NOT SURE IF NEW CUSTOMER DATA DUMP IS DÉJÀ VU

AT&T is investigating claims that 86 million customer records, reportedly containing birthdates, phone numbers, addresses, and 44 million social security numbers, are being sold on cybercrime forums. The company says this appears to be repackaged data from previous breaches, possibly the 2024 Snowflake incident or an earlier 2021 theft, rather than a new hack.

'PATHWIPER' ATTACK HITS CRITICAL INFRASTRUCTURE IN UKRAINE

Cisco Talos discovered "PathWiper," a new Russian wiper malware targeting Ukrainian critical infrastructure through legitimate endpoint administration frameworks. Unlike previous wipers, PathWiper programmatically identifies all connected drives and network paths via APIs before overwriting data with random bytes, potentially more destructive than tools like HermeticWiper used in earlier attacks.

BUSINESS EMAIL COMPROMISE CHECK LIST

A Business Email Compromise (BEC) incident response checklist for Office 365 outlines four phases: isolate the compromised account, contain the threat by resetting credentials and removing unauthorized configurations, eradicate traces of the attacker, and assess impact by reviewing sent emails and shared files. The response includes immediate actions like disabling accounts and changing passwords, followed by forensic analysis, stakeholder notification, and required regulatory reporting. Prevention through proper security measures is easier than incident response, but organizations must learn from incidents to strengthen defenses.

THE COST OF A CALL: FROM VOICE PHISHING TO DATA EXTORTION

Google Threat Intelligence Group (GTIG) reports on threat activity from a group tracked as UNC6040. The group uses vishing to impersonate IT support personnel in convincing attacks targeting employees in multinational corporations into granting access or sharing credentials to their Salesforce platform. In many campaigns, the threat actors convince the victim to add a modified version of the bulk data import tool, Salesforce Data Loader, which is modified to send the data to an attacker-controlled infrastructure.
