Since the initial disclosure of CVE-2023-46805 and CVE-2024-21887 on Jan. 10, 2024, Mandiant has conducted multiple incident response engagements across a range of industry verticals and geographic regions. Mandiant\'s previous blog post, Cutting Edge, Part 3: Investigating Ivanti Connect Secure VPN Exploitation and Persistence Attempts, details zero-day exploitation of CVE-2024-21893 and CVE-2024-21887 by a suspected China-nexus espionage actor that Mandiant tracks as UNC5325. This blog post, as well as our previous reports detailing Ivanti exploitation, help to underscore the different types of activity that Mandiant has observed on vulnerable Ivanti Connect Secure appliances that were unpatched or did not have the appropriate mitigation applied. Mandiant has observed different types of post-exploitation activity across our incident response engagements, including lateral movement supported by the deployment of open-source tooling and custom malware families. In addition, we\'ve seen these suspected China-nexus actors evolve their understanding of Ivanti Connect Secure by abusing appliance-specific functionality to achieve their objectives. As of April 3, 2024, a patch is readily available for every supported version of Ivanti Connect Secure affected by the vulnerabilities. We recommend that customers follow Ivanti\'s latest patching guidance and instructions to prevent further exploitation activity. In addition, Ivanti released a new enhanced external integrity checker tool (ICT) to detect potential attempts of malware persistence across factory resets and system upgrades and other tactics, techniques, and procedures (TTPs) observed in the wild. We also released a remediation and hardening guide |

2022-08-18 08:00:00 | Ukraine and the fragility of agriculture security (lien direct) |  By Joe Marshall.The war in Ukraine has had far-reaching global implications and one of the most immediate effects felt will be on the global supply chain for food. This war-induced fragility has exposed the weaknesses of how we feed ourselves globally. Ransomware cartels and other adversaries are well aware of this and are actively exploiting that fragility. For the past six years, Cisco Talos has been actively involved in assisting public and private institutions in Ukraine to defend themselves against state-sponsored actors. Our involvement stretches the gamut from commercial to critical infrastructure, to election security. Our presence has afforded us unique opportunities and observations about cybersecurity in a macro and micro way. Ukraine has been a frequent victim of state-sponsored cyber attacks aimed at critical infrastructures like power and transportation. Talos is proud to stand with our partners in Ukraine and help defend their critical networks and help users there maintain access to necessary services. Now that Russia has invaded Ukraine, those threats have escalated to kinetic attacks that are wreaking havoc on a critical element of our world: agriculture and our global food supply chain. Even worse is the implications this war will have for future cyber attacks, as fragility is considered a lucrative element in deciding victimology by threat actors like ransomware cartels. To truly grasp the implications of the war in Ukraine, we have to examine how vital Ukrainian agriculture feeds the world, the current state of affairs, and what this means for the global cybersecurity posture to protect agricultural assets. Where there is weakness, there is opportunityRansomware cartels and their affiliates are actively targeting the agricultural industry. Moreover, these actors have done their homework and are targeting agricultural companies during the two times of the year where they cannot suffer disruptions: planting and harvesting. Per the published FBI PIN Alert: “Cyber actors may perceive cooperatives as lucrative targets with a willingness to pay due to the time-sensitive role they play in agricultural production.” This is far from unusual for these adversaries - they are shrewd and calculating, and understand their victims' weaknesses and industries.

2022-08-06 10:46:21 | CISO workshop slides (lien direct) | A glossy, nicely-constructed and detailed PowerPoint slide deck by Microsoft Security caught my beady this morning. The title 'CISO Workshop: Security Program and Strategy' with 'Your Name Here' suggests it might be a template for use in a workshop/course bringing CISOs up to speed on the governance, strategic and architectural aspects of information security, but in fact given the amount of technical detail, it appears to be aimed at informing IT/technology managers about IT or cybersecurity, specifically. Maybe it is intended for newly-appointed CISOs or more junior managers who aspire to be CISOs, helping them clamber up the pyramid (slide 87 of 142): | Malware Vulnerability Threat Patching Guideline Medical Cloud | Uber APT 38 APT 37 APT 28 APT 19 APT 15 APT 10 APT 34 Guam |
