NetSecurity Cyber Threat Brief | July 2023
2023, the threat landscape witnessed a significant increase in Clop ransomware accounted for a staggering 34 percent of overall observed This Russian-linked malicious ransomware group has continued to evolve and wreak havoc on various organizations across the globe, leaving more than 160 victims just
Apart from Clop, several other ransomware variants made their mark in July 2023. The top five ransomware of the month,Clop, were LockBit 3.0, 8Base, ALPHV, and BianLian. These ransomware have been responsible for a significant number of attacks, highlighting the diverse range of threats organizations face in the digital landscape.
Meanwhile, Microsoft researchers identified and mitigated a China-based threat actor group called Storm-0558 targeting of customer email. The company claimed Storm-0558 used forged authentication tokens to access user emails from approximately 25 organizations, including government agencies and consumer accounts.
In addition to the ransomware and nation-state threat actor onslaught, July 2023 saw several zero-day vulnerabilities making headlines. These vulnerabilities exposed vulnerabilities in popular software such as MoveIt [CVE-2023-34362], Citrix ADC [CVE-2023-3519], Ivanti EPMM [CVE-2023-35078]. Zero-day vulnerabilities are particularly concerning as they exploit unknown flaws, making it difficult for organizations to defend against them. The discovery of these vulnerabilities emphasizes the importance of timely patching and maintaining robust security measures.
The prevalence of Clop ransomware and the emergence of zero-day vulnerabilities in crucial software serve as stark reminders of the ever-evolving threat landscape. Organizations must prioritize cybersecurity and adopt a multi-layered defense strategy to mitigate the risk of falling victim to these malicious attacks.
As we move forward, it is imperative for organizations to stay informed about the latest threats and vulnerabilities, and to collaborate with cybersecurity experts to enhance their overall security posture. By doing so, they can effectively safeguard their systems, data, and reputation from the relentless onslaught of cyber threats.
