Criminals and nation states are already trying to exploit the vulnerability According to Microsoft’s threat intelligence team , the majority of the attacks related to the Log4j vulnerability ...
November and December: On November 24, Chen Zhaojun of Alibaba's Cloud Security Team reported a zero-day vulnerability (later dubbed Log4Shell) involving the use of arbitrary code execution in the ubiquitous Java logging framework software Log4j.
A zero-day (also known as a 0-day) is a vulnerability in software or hardware that is typically unknown to the vendor and for which no patch or other fix is available. The vendor thus has zero days to prepare a patch, as the vulnerability has already been described or exploited.
Darktrace has claimed that it has the capability to defend against zero-day attacks, for example during the log4j vulnerability exploits. [27] In the wake of the pandemic, Darktrace reported rising demand for its technology as sophisticated cyber attacks surged. Speaking in 2021, Nicole Eagan, chief strategy officer, said:
One cybersecurity research group noted their use of six different zero-day exploits in 2015, a technical feat that would require large numbers of programmers seeking out previously unknown vulnerabilities in top-of-the-line commercial software. This is regarded as a sign that Fancy Bear is a state-run program and not a gang or a lone hacker. [1 ...
Exploits that remain unknown to everyone except the individuals who discovered and developed them are referred to as zero-day or "0day" exploits. After an exploit is disclosed to the authors of the affected software, the associated vulnerability is often fixed through a patch , rendering the exploit unusable.
