Circumventing inbound traffic rule by faking reply traffic

My question is about security groups/firewalls and protecting a virtual private cloud from the external world. Here is a description of VPC default policy for inbound/outbound traffic (on AWS):

Each security group by default contains an outbound rule that allows access to any IP address. It’s important to note that when an instance sends traffic out, the security group will allow reply traffic to reach the instance, regardless of what inbound rules are configured.

I was wondering if there exists an attack vector where a malicious user tries to circumvent the VPC’s inbound policy (i.e. block all traffic) by tricking it into thinking that the incoming traffic is a “reply” traffic? Does such attack have a name in the literature?

I can also think of a scenario where a target machine T (within a VPC) sends a request to some valid server V, but the malicious user M sends a malicious response to T (tricking it into believing that it comes from V) before T receives the actual response from V, thence circumventing T‘s inbound traffic policy.

Does the reply to the Message cantrip have a time/distance limit?

The message cantrip says the following:

You point your finger toward a creature within range and whisper a message. The target (and only the target) hears the message and can reply in a whisper that only you can hear.

The spell itself has a duration of 1 round and a range of 120 feet, but I assume this is for the caster’s “outgoing” message. Is there a time limit or a distance limit on the recipient’s reply?

I ask this because a player claims that the recipient of the message can reply any time in the future at any distance, because the spell does not specify that, and they have therefore used the message cantrip as a way to have an NPC tell them when someone is ready to collect (i.e. casting message on the NPC, with the message being “reply to this message spell when you’re done“).

I believe that the intent is that the recipient is expected to reply straight away, but that isn’t specified. For contrast, the sending spell does specify when the recipient is allowed to respond:

You send a short message of twenty-five words or less to a creature with which you are familiar. The creature hears the message in its mind, recognizes you as the sender if it knows you, and can answer in a like manner immediately.

Sending says that the recipient must reply immediately, whereas message does not specify when the recipient must reply, hence my player claiming that there is no time limit.

Regarding the distance thing, this is also treading on the toes of the sending spell somewhat, except that the caster of message still has to be within 120 feet of the recipient (it’s only the recipient that seems to have no limit on distance), whereas sending allows the caster to be the one to initiate long-distance communication.

Is my player correct? Can the recipient of a message really reply after any length of time after they receive the message, and over any distance?

[ Law & Ethics ] Open Question : Get in trouble for offensive/hateful reply email?

so a friend of mine got an email from a rep of his new credit card company saying that he could use his new card before it got to him through their app (new card was supposed fo arrive by mail in 2 weeks). he was in a bad mood and replied that the rep should f*k off and stop pressuring him, and that he would use their sh*tty card whenever he feels like it. and that the rep should kill himself. following his reply he got an email from the company saying that they closed his account due to breaking terms of fairuse policy. he then apologized and they said they appreciate the apology but will not reopen his account. he is worried. can he get in trouble for the things he said?

vsftpd Error: Server returned unroutable private IP address in PASV reply

I have followed this tutorial to set up my FTP server, using vsftpd.

When I am testing the FTP serve using https://ftptest.net I get the following error:

Error: Server returned unroutable private IP address in PASV reply

  • Make sure the server is configured to allow passive mode connections.
  • If the server is behind a NAT router, make sure the server knows its external IP address.
  • The range of ports used for passive mode must be opened in all involved firewalls.
  • The range of ports used for passive mode must be forwarded by all involved NAT routers.
  • Try uninstalling all firewalls and plug your computer directly into your modem, thus bypassing the router.

“Email me at” or “reply to this email”?

The situation:

I’m emailing new customers with some general info they need to set up their account. Usually, this information is more than enough. But, there’s a possibility that they might have some questions left. So, I want to be polite and at the end of the letter, I suggest they email me if they have any questions.

The question:

Is it ok to say, the following:

For any questions, please consult our Help Desk – or email me at email@example.

Considering, that the email I give in the sentence above is the same I send my letter from.

Or is it better to say:

For any questions, please consult our Help Desk – or reply to this email.
