nthing KeepAss! The UX is not the best but it seems pretty bombproof from a functionality standpoint. Have used it for years and years.

Why are you using the Keepass2Android keyboard? Are you on an older version of Android? Since version 8 (Oreo), Android has had an autofill service and Keepass2Android supports it. You tap the autofill button.

Sometimes in some (badly made?) apps the autofill just doesn't show up, forcing me to use the keyboard.

Nalin posted:

Keepass2Android will say it can't find an autofill entry so you tap the "Select another entry" button, navigate to the password you want, and tell it to use that one. It will then save the app affiliation into your database.

This seems to only persist in some local cache and never get uploaded back to cloud (I use Google Drive). Whenever my phone downloads an updated database, the app associations are gone. Am I doing it wrong?

Yeah. That isn't right. Does the application itself not re-upload your database on changes? Maybe it's a problem with Google Drive or the Keepass2Android integration with it? I have my database on Dropbox and making any changes on my phone causes it to save the change back to Dropbox.

The app association is saved inside your password entry under the "Advanced" tab. It makes a new string field.

[CVE-2019-14899] Inferring and hijacking VPN-tunneled TCP connections.

quote:

We have discovered a vulnerability in Linux, FreeBSD, OpenBSD, MacOS, iOS, and Android which allows a malicious access point, or an adjacent user, to determine if a connected user is using a VPN, make positive inferences about the websites they are visiting, and determine the correct sequence and acknowledgement numbers in use, allowing the bad actor to inject data into the TCP stream. This provides everything that is needed for an attacker to hijack active connections inside the VPN tunnel.

This vulnerability works against OpenVPN, WireGuard, and IKEv2/IPSec, but has not been thoroughly tested against tor, but we believe it is not vulnerable since it operates in a SOCKS layer and includes authentication and encryption that happens in userspace. It should be noted, however, that the VPN technology used does not seem to matter and we are able to make all of our inferences even though the responses from the victim are encrypted, using the size of the packets and number of packets sent (in the case of challenge ACKs, for example) to determine what kind of packets are being sent through the encrypted VPN tunnel.

Root cause is:

quote:

sysctl.d: switch net.ipv4.conf.all.rp_filter from 1 to 2

This switches the RFC3704 Reverse Path filtering from Strict mode to Loose mode. The Strict mode breaks some pretty common and reasonable use cases, such as keeping connections via one default route alive after another one appears (e.g. plugging an Ethernet cable when connected via Wi-Fi).

The strict filter also makes it impossible for NetworkManager to do connectivity check on a newly arriving default route (it starts with a higher metric and is bumped lower if there's connectivity).

Kernel's default is 0 (no filter), but a Loose filter is good enough. The few use cases where a Strict mode could make sense can easily override this.

The distributions that don't care about the client use cases and prefer a strict filter could just ship a custom configuration in /usr/lib/sysctl.d/ to override this.

what?

Second paragraph of the oss-sec post:

quote:

Most of the Linux distributions we tested were vulnerable, especially Linux distributions that use a version of systemd pulled after November 28th of last year which turned reverse path filtering off. However, we recently discovered that the attack also works against IPv6, so turning reverse path filtering on isn't a reasonable solution, but this was how we discovered that the attack worked on Linux.
The flaw has nothing directly to do with systemd, it just happened to flip a switch that exposed the flaw over IPv4. For some reason the systemd haters (not accusing you of being one, just maybe inadvertently getting information from one) have latched on to this one even though it also affects entirely different kernels where systemd doesn't even exist.

Funny enough their database of emails is now incredibly valuable because if this is the kind of security they're teaching it'd be useful to cross-reference with company emails to know where to find similarly brain-dead security vulns.

Microsoft would be dumb not to put out their own password manager. Put it behind their SSO and fancy things like conditional access and push MFA, integrate with their admin interfaces and logging... There are a ton of companies out there who just don't have users capable of something like 1Password and IT departments and training that don't have the time. But if Microsoft makes it significantly easier for only a little less secure, I see it taking off like wild fire.

They will definitely put it behind all their premium poo poo so the majority of their customers won't be able to afford it.

It's rumored to be part of their Office 365 "Life" rebranding for consumers, so it's very likely not going to be unaffordable. Of course, depends on whether you can subscribe individually or have to take the whole Office 365 package to get it (currently $10/month).

E5 just seems like a no brainer for a business to me, and I am no Microsoft fanboy. They just made MFA free for all of their customers, which is a step in the right direction. We'll see. It's not like decent password managers for business/enterprise are cheap to begin with.

Mfa without those basic custom conditional access policies isnt anything more than what you were already getting with an e3.

How does it block hidden security cameras if they’re hidden? Or do you cover yourself in stickers so the hidden cameras can’t identify you?

I have a thing for courageous dongles

What are people's thoughts on record size limits for SPF records? A lot of documentation talks about limiting to 500 characters to stay inside the MTU so lookups don't revert to TCP mode out of concern that some systems might be UDP DNS only. But for that to be the case, wouldn't those mail systems need to be connecting over dial-up to get choked down to an MTU that small? It seems like 1400 characters is a more realistic cap given a typical 1500 mtu plus overhead for ipsec encapsulation and anything else, but the recommendations always seem to be 500. Are people just parroting a 15 year old consideration that doesn't matter any more or am I missing something?

the only real limit is 10 lookups afaik in accordance with the rfc, i've never heard of this limitation before and it sounds really dumb

Well, its a limitation of DNS which is the underpinning. Beyond the 10 DNS lookup limit, there is also a limit on the number of items returned in a MX record (which I discovered with some goofy-rear end .mil mail domain who's mx record resolved to 12 mail gateways. Resolution of A records triggered from MX lookups are counted separately from the other 10 lookup limit), and you can only make the TXT records in strings of 255 characters which are encapsulated in quote and then stripped and concatenated by the SPF engine that is processing the record. The RFC is a bit loving nuts, but most of the really weird poo poo is due to limitations of DNS.

DNS prefers UDP transport mode by default but will generally refuse to return a record that is larger than your MTU because if a fragment gets lost on re-assembly while TCP would recover without having to re-run the entire query. So most DNS clients will then revert to a TCP lookup in that scenario, but that's slower due to the extra round trips so it doesn't happen by default. From an absolute technical limit, an SPF record can be up to 64k characters long which is the maximum size of a TXT record but you still have to honor the individual string length limits. The common consensus that I see is that if your lookup has to fail back to UDP you're loving up and risking causing resolution problems for some receiving mail servers, so avoid it.
