ESET takes part in global operation to disrupt Lumma Stealer

ESET has collaborated with Microsoft, BitSight, Lumen, Cloudflare, CleanDNS, and GMO Registry in a global disruption operation against Lumma Stealer, an infamous malware-as-a-service (MaaS) infostealer. The operation targeted Lumma Stealer infrastructure with all known C&C servers in the past year, rendering the exfiltration network, or a large part of it, nonoperational. Key points of this…

Power amplifiers that oscillate—deliberately. Part 1: A simple start.

Power amplifiers that oscillate—deliberately. Part 1: A simple start.

Editor’s Note: This DI is a two-part series. In Part 1, Nick Cornford deliberately oscillates the TDA7052A audio power amplifier to produce a siren-like sound and, given the device’s distortion characteristics, a functional Wien bridge oscillator. In Part 2, Cornford minimizes this distortion and adds amplitude control to the circuit. When audio power amplifiers oscillate,…

Designing power supplies for industrial functional safety, Part 1

A power supply unit is one of the most crucial components in an electronics system, as its operation can affect the entire system’s functionality. In the context of industrial functional safety, as in IEC 61508, power supplies are considered elements and supporting services to electrical/electronic/programmable electronic (E/E/PE) safety-related systems (SRS) as well as other subsystems….
