Distributed denial-of-service attacks appear to be returning as a significant if episodic nuisance. AtlasVPN puts the number of DDoS attacks in the first half of 2021 at a record 4.5 million. One recent victim is North Carolina-based voice-over-IP provider Bandwidth, which, BleepingComputer reports, began experiencing outages on Saturday.
NSA and CISA late yesterday released guidance on how to configure and use virtual private networks (VPNs) safely and securely. VPNs provide access to protected networks, and are therefore especially attractive targets for cyberattacks. The agencies' nine-page factsheet concludes, "Remote access VPNs are entryways into corporate networks and all the sensitive data and services they have. This direct access makes them prized targets for malicious actors. Keep malicious actors out by selecting a secure, standards-based VPN and hardening its attack surface. This is essential for ensuring a network’s cybersecurity."
Russian authorities have detained Ilya Sachkov, founder and chief executive of cybersecurity firm Group IB on suspicion of "state treason," Reuters reports. Authorities searched Group IB's Moscow offices yesterday. TASS was authorized to quote presidential spokesman Dmitry Peskov as saying the Kremlin was aware of the arrest from "media reports," but that he had no further information to offer. Group-IB is confident that Sachkov will be vindicated, and that Dmitry Volkov will run the company during Sachkov's detention. The company says it's continuing operations, and that customers' data are safe in its "decentralized infrastructure." The company has international headquarters in London, Singapore, Dubai, and New York; it represents Singapore as its primary headquarters.
