Motherboard shared a letter to Congress that shows the US National Security Agency, Central Intelligence Agency and other members the Intelligence Community use ad-blockers on their networks for security protection. The IC chief information officer stated that the IC implemented network-based ad blocking technologies and used information from multiple layers, including Domain Name System information to block malicious and unwanted advertising content.

An ad blocker can be used to improve your browsing experience. However, the tools also offer defense benefits. An attacker who tries to send malicious ads through unscrupulous advertising networks or taint legitimate-looking advertisements can steal data, sneak malware onto your device, and sometimes exploit web vulnerabilities. The IC regards ads as an unneeded risk and even a threat, indicating that there are long-standing problems in the industry. In recent years, the NSA and Cybersecurity and Infrastructure Security Agency issued guidance advising that ad blocking be used as a security measure. However, the IC was not required to adopt this measure. Its members deployed ad blockers voluntarily.

Rostelecom's security division was able to take down a part of the botnet that was infamous this week thanks to a flaw in the software. Rostelecom was able to sinkhole a portion of the system because of this error. Botnets are a group of infected devices that has been used to coordinate coordinated operations. These platforms are frequently used to launch DDoS attacks. In this scenario, actors send a torrent of junk traffic at the targeted web systems in an effort to overload them.

Meris is the most powerful botnet currently available to cybercriminals. It is believed to consist of approximately 250,000 systems working together. It was used to attack targets in Russia, the United States and the United Kingdom. Rostelecom's partial takedown was significant because Meris attacks can be very powerful and difficult to defeat. A Meris attack against Yandex, the Russian tech giant, broke the record for the largest volumetric DDoS attack. Yandex was able to defend itself against this attack.
