Cache Poisoning | Breaking Cybersecurity News | The Hacker News

Cybersecurity researchers on Wednesday disclosed 14 vulnerabilities affecting a commonly-used TCP/IP stack used in millions of Operational Technology (OT) devices manufactured by no fewer than 200 vendors and deployed in manufacturing plants, power generation, water treatment, and critical infrastructure sectors. The shortcomings, collectively dubbed "INFRA:HALT," target NicheStack, potentially enabling an attacker to achieve remote code execution, denial of service, information leak, TCP spoofing, and even DNS cache poisoning. NicheStack (aka InterNiche stack) is a closed-source TCP/IP stack for embedded systems that is designed to provide internet connectivity industrial equipment, and is incorporated by major industrial automation vendors like Siemens, Emerson, Honeywell, Mitsubishi Electric, Rockwell Automation, and Schneider Electric in their programmable logic controllers (PLCs) and other products. "Attackers could disrupt a building's HVAC system or take

A group of academics from the University of California and Tsinghua University has uncovered a series of critical security flaws that could lead to a revival of DNS cache poisoning attacks. Dubbed " SAD DNS attack " (short for Side-channel AttackeD DNS), the technique makes it possible for a malicious actor to carry out an off-path attack, rerouting any traffic originally destined to a specific domain to a server under their control, thereby allowing them to eavesdrop and tamper with the communications. "This represents an important milestone — the first weaponizable network side channel attack that has serious security impacts," the researchers said. "The attack allows an off-path attacker to inject a malicious DNS record into a DNS cache." Tracked as CVE-2020-25705, the findings were presented at the ACM Conference on Computer, and Communications Security (CCS '20) held this week. The flaw affects operating systems Linux 3.18-5.10, Windows Serv

Even as cyber threats become increasingly sophisticated, the number one attack vector for unauthorized access remains phished credentials ( Verizon DBIR, 2024 ). Solving this problem resolves over 80% of your corporate risk, and a solution is possible.  However, most tools available on the market today cannot offer a complete defense against this attack vector because they were architected to deliver probabilistic defenses. Learn more about the characteristics of Beyond Identity that allow us to deliver deterministic defenses.  The Challenge: Phishing and Credential Theft Phishing attacks trick users into revealing their credentials via deceptive sites or messages sent via SMS, email, and/or voice calls. Traditional defenses, such as end-user training or basic multi-factor authentication (MFA), lower the risk at best but cannot eliminate it. Users may still fall prey to scams, and stolen credentials can be exploited. Legacy MFA is a particularly urgent problem, given that attackers
