Continuous Monitoring and Protection
The threat of leaking data if a ransom is not paid is a common tactic amongst ransomware actors. In this case, the group would still leak data even if ransom was paid. By using this model, the group was setting themselves up to not get paid by anyone because there would be no benefit to paying. Although this is a risk taken by companies paying a ransom, most groups do not follow this model to…
Read MoreThis new recommendation from Microsoft demonstrates how adding over-encompassing AV exclusions can negatively impact and organization’s security. Especially in the current threat landscape, many actors make use of PowerShell and malicious IIS extensions to perform their attacks. Having these exclusions in place allows for a large gap in visibility where the threat actors can go unnoticed. On top of removing these exclusions and following the other recommendations from Microsoft, it is also recommended to frequently…
Read MoreContent delivery network (CDN) service provider Edgio has added a new Distributed Denial of Service (DDoS) scrubbing ability along with improved Web Application and API Interface (WAAP) to its network security offering. Designed to reduce severe damages from sophisticated DDoS attacks, Edgio’s scrubbing solution impersonates the customer’s network by routing the customer’s IP traffic through its scrubbing point-of-presence (PoP) and only sending the “clean” traffic back to the customer’s infrastructure, according to Richard Yew, senior…

Read MoreProof-of-concept exploit code is now available for a critical vulnerability in Fortinet FortiNAC appliances and attackers have already started using it in the wild. Users are advised to patch their systems as soon as possible. FortiNAC is a zero-trust network access solution that can be deployed both as a hardware device or as a virtual machine appliance. It is used for network segmentation, visibility, and control of devices and users connected to the network. As…
Read MoreAt a time when almost all software contains open source code, at least one known open source vulnerability was detected in 84% of all commercial and proprietary code bases examined by researchers at application security company Synopsys. In addition, 48% of all code bases analyzed by Synopsys researchers contained high-risk vulnerabilities, which are those that have been actively exploited, already have documented proof-of-concept exploits, or are classified as remote code execution vulnerabilities. The vulnerability data…
Read MoreAlthough no one has claimed responsibility for the attack, if one actually took place, it is likely it was carried out by a pro-Ukrainian hacktivist group. Hacktivist groups have carried out multiple attacks on behalf of both Ukraine and Russia over the course of the conflict. Even though President Putin continues to erroneously blame the West and Ukraine for Russia’s invasion, multiple reports identified Russian backed cyber-attacks on Ukrainian organizations in the months leading up…
Read MoreSocial media sites like Facebook are common vectors for threat actors to spread malware. Due to this, it is highly recommended to avoid downloading files from social media sites, particularly in cases where the source is unknown or untrusted. Even from known sources, it is recommended to carefully vet any links or files that are shared, as the source could be compromised. It is also recommended to maintain good endpoint security controls on all devices…
Read MoreThis situation highlights the potential impact of cyber attacks on the food supply chain, which is a critical infrastructure that requires secure and resilient systems. The disruption of food supplies can have severe consequences for public health and safety, as well as economic and social stability. The continuance of ransomware attacks against businesses that are part of critical infrastructure emphasizes the need for organizations to continue to invest in cybersecurity and risk management processes, people,…
Read MoreAI-focused cybersecurity vendor Darktrace has announced the release of Newsroom, a new detection and warning system for critical vulnerabilities that uses open-source intelligence (OSINT) sources to identify threats posed to businesses. Newsroom leverages deep and AI-assisted knowledge of a customer’s external attack surface to gauge its exposure to detected vulnerabilities and provides a summary of exploits, affected software and assets within the organization, Darktrace stated. It also provides vulnerability mitigation guidance specific to businesses, while…
