| CVE-2020-17087 | Windows Kernel Buffer Overflow Enables Local Privilege Escalation (CVE-2020-17087) CVE-2020-17087 is a local elevation-of-privilege flaw in the Windows kernel caused by an incorrect buffer size calculation (CWE-131), producing a kernel buffer overflow; public analyses from Microsoft and Google's disclosure place the vulnerable code in the kernel's cryptographic driver (cng.sys). A local attacker with low privileges can trigger the overflow without user interaction, gaining code execution in kernel context and effectively full control of the host (high impact on confidentiality, integrity, and availability; CVSS 7.8). Every Windows system on the affected builds is exposed: Windows 10 versions 1507 through 20H2, Windows 7, 8.1, RT 8.1, and Windows Server 2008, which at disclosure meant essentially the entire supported Windows install base. The flaw was exploited as a zero-day in the wild: Google disclosed its use in targeted attacks, reportedly chained with a Chrome zero-day, and CISA added it to the KEV catalog on 2021-11-03; EPSS currently estimates a 5.4% probability of exploitation within 30 days (92nd percentile), with ransomware association listed as unknown. Do: Apply Microsoft's November 2020 Patch Tuesday security updates to all affected Windows 10, Windows 7, 8.1, RT 8.1, and Windows Server 2008 systems; this is CISA's required action for the KEV listing and no official workaround is known. Prioritize hosts where untrusted users can log on locally or via RDP, and ensure Chromium-based browsers are fully updated since this kernel bug was reportedly chained with a Chrome zero-day. After patching, verify the November 2020 update is installed; treat any ransomware association as currently unconfirmed. | 7.8 | 5% | KEV |

Stop thinking of cybersecurity as a problem: Think of it as a game
Cybersecurity isn’t a battle that’s ultimately won, but an ongoing game to play every day against attackers who want to take your systems down. We won’t find a one-size-fits-all solution for the vulnerabilities that were exposed by the pandemic. Instead, each company needs to charge the field and fend off their opponent based on the rules of play.
Making history: The pandemic, disaster recovery and data protection
Let’s face it, because of the pandemic a lot of companies were caught off guard with insufficient plans for data protection and disaster recovery (DR). That isn’t easy in the best of times, never mind during a pandemic. Even those with effective strategies now must revisit and update them.
