Welcome to your daily cybersecurity podcast.
Amazon disclosed the detection of a North Korea-linked infiltration during an IT hiring process. A system administrator claimed to be US-based was identified through persistent keyboard latency exceeding 110 milliseconds to Seattle servers, indicating intercontinental remote operation. The control infrastructure was traced to China. Since April 2024, Amazon reports blocking more than 1,800 fraudulent hiring attempts linked to North Korea, with a 27 percent quarterly increase.
A Russian APT actor is conducting a credential phishing campaign targeting government entities across the Baltics and the Balkans. The attacks rely on HTML attachments masquerading as PDF documents, embedding institutional decoys and fake authentication forms. Credentials are exfiltrated via formcarry.com, with consistent JavaScript and regex reuse observed since at least 2023.
Microsoft confirmed a global Microsoft Teams outage impacting message delivery across all regions and clients. The incident started at 14:30 ET and was fully resolved one hour later. No indicators of malicious activity were reported.
A malware campaign abuses Microsoft Office documents, SVG files, and compressed archives to compromise Windows systems. The attack chain exploits CVE-2017-11882, uses PNG steganography, and process hollowing via RegAsm.exe to deliver RATs and information stealers.
ATM jackpotting attacks in the United States have been attributed to a criminal group deploying the Ploutus malware via physical access to ATMs. The tradecraft involves hard drive replacement or modification to control cash-dispensing modules. Losses are estimated to exceed $40 million since 2020.
Don’t think, patch.
