Heartbleed is a significant vulnerability (CVE-2014-0160) that was identified in the OpenSSL cryptographic software library in 2014. This flaw allows an attacker to read server memory and send additional data, leading to potential information leaks – hence the term "bleeding out data". The vulnerability resulted from a flaw in the implementation of the Heartbeat Extension for the Transport Layer Security (TLS) and Datagram Transport Layer Security (DTLS) protocols. OpenSSL 3.0.4 was one of the versions affected by this vulnerability. The impact of Heartbleed was far-reaching due to the widespread use of OpenSSL. Notably, cyber threat group Leafminer was observed by Symantec scanning for the Heartbleed vulnerability from an attacker-controlled IP address. Once the bug was disclosed, scans began for instances of the vulnerability, highlighting its potential for exploitation. Despite the introduction of other notable vulnerabilities like Log4j, Heartbleed remains one of the most impactful and well-known. The Heartbleed vulnerability was among the first to be branded with a name and logo, a practice that has since been adopted for other significant vulnerabilities. This branding strategy, described as the "Branded Vulnerabilities Trend", played a crucial role in garnering media attention and raising awareness about the issue. However, it's important to note that while Heartbleed was a serious vulnerability, not all named bugs are as severe as they might seem, according to Dustin Childs, head of Threat Awareness at Trend Micro's Zero Day Initiative (ZDI).
