Company web names hijacked via outdated cloud DNS records
2020-07-07 14:09

Most cloud services keep their DNS cache times, known in the jargon as TTLs or time-to-live entries, pretty small these days in order to help their services adapt more quickly to changes in network load. Hacking your DNS entries is not quite as good a result for the crooks as taking over your actual web server - they won't have your web certificate to authenticate HTTPS traffic, and they'd need to clone a huge amount of your site to make a realistic facsimile - but it's still extremely dangerous, and potentially very damaging for your brand. In the cases tracked by Edwards, it seems that a bunch of crooks have been keeping their eyes on unused Azure server names that still have trusted DNS records referring to them, and reviving those defunct server names to produce believable URLs for scams and malware campaigns.

Fake “DNS Update” emails targeting site owners and admins

The link took them to a "Surprisingly believable" phishing page with logos and icons that matched their service provider, and instructed them to enter their WordPress account username and password to start the update. "The scam then shows you some fake but believable progress messages to make you think that a genuine 'site upgrade' has kicked off, including pretending to perform some sort of digital 'file signing' at the end," Sophos's security proselytiser Paul Ducklin explained.

We care about your privacy and the protection of your domains, so we will soon be upgrading them, from basic Domain Name System to Domain Name System Security Extensions.

Encrypted DNS, as its name suggests, encrypts those queries to shield them from snoops and meddlers. A year later, a research paper presented at a Usenix conference underscored the need for better security when it reported that about 8.5 per cent of DNS queries were intercepted by service providers.

DNS this week stands for Drowning Needed Services: Design flaw in name server system can be exploited to flood machines offline
2020-05-21 10:52

Dubbed NXNSAttack, the flaw [PDF] can be abused to pull off a classic amplification attack: you send a small amount of specially crafted data to a DNS server, which responds by sending a lot of data to a victim's server. The recursive server contacts your DNS server for your dot.com for that information.
