Nonprofit organisation that scans the internet for vulnerable and compromised systems, sharing threat intelligence with defenders and national CERTs.
Attackers are exploiting Zimbra Collaboration Suite flaw CVE-2026-73570, which Synacor fixed quietly in 10.1.20 on July 20 and disclosed on August 13. An upgrade closes the injection path, but a web shell written earlier stays on disk until someone finds it.
Reality
Microsoft says attackers are using CVE-2026-73570 to run commands on Zimbra mail servers with one crafted email and no login. Zimbra shipped the fix in 10.1.20 on July 20, 24 days before disclosure, so anyone who waited for the advisory to patch was already late.
