SID 54509-54511, 54516-54518, 54521-54525, 54534, 54535
- →Monitor dns.exe for processing of oversized SIG resource records (>=64KB) over TCP — the vulnerability is triggered when a DNS response containing a SIG record with a signature field causing an integer overflow (result >65,535 bytes) is parsed by dns.exe!SigWireRead, leading to a heap buffer overflow. ↗
- →Detect DNS TCP sessions where the 2-byte length prefix indicates a message approaching or at the 65,535-byte maximum — exploitation requires DNS-over-TCP (triggered via TC flag truncation fallback) to deliver the oversized SIG payload. ↗
- →Look for DNS responses containing SIG (type 24) resource records with anomalously large RDATA/signature fields, particularly where the combined allocation formula for the record would exceed 65,535 bytes. ↗
- →Monitor for dns.exe crashes or unexpected termination on Windows Server systems — a crash of dns.exe is an indicator of exploitation attempts against CVE-2020-1350. ↗
- ·A registry-based workaround exists that does not require restarting the server — it can be applied when immediate patching is not practical, but the official patch should be applied as soon as possible. ↗
- ·Only Windows DNS Server (dns.exe) is affected; non-Microsoft DNS server implementations are not vulnerable. ↗
- ·The vulnerability affects all Windows Server versions from 2003 to 2019; DNS servers are typically also domain controllers, making exploitation impact domain-wide. ↗
- ·Exploitation requires the attacker to control a malicious NS record that the victim DNS server is directed to query — direct exploitation without this redirection step (e.g., via a registered domain with a malicious NS) is the primary attack vector. ↗

CVE-2020-1350 [CRITICAL] Windows DNS Server Remote Code Execution Vulnerability
Windows DNS Server Remote Code Execution Vulnerability
Description: A remote code execution vulnerability exists in Windows Domain Name System servers when they fail to properly handle requests. An attacker who successfully exploited the vulnerability could run arbitrary code in the context of the Local System Account. Windows servers that are configured as DNS servers are at risk from this vulnerability.
To exploit the vulnerability, an unauthenticated attacker could send malicious requests to a Windows DNS server.
The update addresses the vulnerability by modifying how Windows DNS servers handle requests.
FAQ: This vulnerability has a CVSS Base score of 10. How bad is this?
We consider this to be a wormable vulnerability, meaning that it has the potential to spread via malware between

Analyzing Attack Opportunities Against Information Security Practitioners
In partnership with vx-underground, SentinelOne recently ran its first Malware Research Challenge, in which we asked researchers across the cybersecurity community to submit previously unpublished work to showcase their talents and bring their insights to a wider audience.
Today’s post is the second in a series highlighting the best entries. Jared Stroud (@DLL_Cool_J / Arch Cloud Labs) explores the risks faced by security researchers from attacks by APTs and other threat actors through compromise of security research tools. The study includes discussion of a novel attack vector through popular open-source reverse engineering platform, Ghidra.

Zero-day vulnerability attacks have emerged as a major cybersecurity threat in the last few years. Organizations most often targeted include large enterprises and government/Federal agencies. However, any organization, regardless of its size, business, or industry, is a potential target for zero-day threats.
Most notably, already publicly disclosed. This means that one out of every four zero-day exploits detected could potentially have been avoided if a more thorough investigation and patching effort had been pursued. In 2021, around 58 zero-day vulnerabilities we

# Executive Summary
Unit 42 researchers analyzed network attack trends over Winter 2020 and discovered many interesting exploits in the wild. During the period of Nov. 2020 to Jan. 2021, the majority of the attacks we observed were classified as critical (75%), compared to the 50.4% we reported in the fall of 2020. Several newly observed exploits, including CVE-2020-28188, CVE-2020-17519, and CVE-2020-29227, have emerged and were continuously being exploited in the wild as of late 2020 to early 2021.

‘Wormable’ Flaw Leads July Microsoft Patches
blogs_krebs·2020-07-14·CVSS 10.0
[CRITICAL] ‘Wormable’ Flaw Leads July Microsoft Patches
Microsoft today released updates to plug a whopping 123 security holes in Windows and related software, including fixes for a critical, “wormable” flaw in Windows Server versions that Microsoft says is likely to be exploited soon. While this particular weakness mainly affects enterprises, July’s care package from Redmond has a little something for everyone. So if you’re a Windows (ab)user, it’s time once again to back up and patch up (preferably in that order).
Microsoft said it is not aware of reports that anyone is exploiting the weakness (yet), but the flaw has been assigned a CVSS score of 10, which translates to “easy to attack” and “likely to be exploited.”
