Attack mot NS1s DNS-tjänst

Sedan ett par dagar så har NS1 DNS-tjänst attackerats vilket påverkar tillgången till en stor rad tjänster och webbplatser.

Over the course of last week, we sustained dozens of large DDoS attacks, ranging in strategy from simple volumetric attacks, to complex direct DNS lookup attacks, to concentrated attacks against our upstream network providers and other vendors. These attacks are an escalation above and beyond a recently observed increase in malicious activity broadly targeting the DNS, CDN, and internet infrastructure industries.

Attackerna görs mot NS1 direkt, inte mot någon av deras kunder utan det är en centralt riktad attack. Det är dessutom i perioder en mycket omfattande attack.

The attack traffic was also mobile – with the largest ongoing assaults directed at our European infrastructure, but also migrating to attack our network in the western US and Asia. By combining multiple highly targeted techniques, the attackers created a complex and evolving situation that did result in brief periods of packet loss at several of our nodes. This caused partial DNS delivery service failure during those periods, particularly in Europe.

Går det trögt att surfa, svarar vissa webbtjänster inte alls eller långsamt så kan detta vara förklaringen.
