[ARIN-consult] Consultation on Password Security for ARIN Online Accounts

[Mike Burns]

Thanks John. For what it's worth, I would guess that the miscreants would not be expecting a long-term access to any blocks brought under control in this manner, and for this reason would want to realize the most revenue possible in a short time. And this probably means spamming.  For which rdns has great value.

I would put another padlock on rdns changes, is it possible to have staff review changes in rdns delegation in anything like real-time?  

Regards,
Mike

Mike, while we are not entirely sure of the motives, you have definitely outlined a few that we are looking at. See Inline:

    Does anybody know why ARIN and RIPE are being attacked in this way?
    Is the purpose merely credential discovery or would access be used in a
    nefarious way?

(JS) ARIN believes that the purpose of credential stuffing is for the purpose of using the resources associated with the account in nefarious ways. 

    In ARIN these credentials would not allow for the sale of an address block.

(JS) that is correct, the rigorous process and procedure for completing a transfer would not allow for someone that merely has access to an account resources to transfer them. 

    But they could allow for rDNS entries that would enable mailing on a
    hijacked block.

(JS) that is correct as well and yes, we have seen instances of this in the past. We have learned that several "market places" for leasing of resources require proof of control of the IP resources in order to list them. This is one of the "prove you control these blocks" methods.

    And I suppose they could facilitate the leasing out of the block through ROA
    generation.

(JS) Again correct, we have also confirmed that this is another "proof of control" that is used.

    Any thoughts on the reason behind these recent attacks on two RIRs?

(JS) ARIN continues to capture forensics and will absolutely cooperate with law enforcement agencies when deemed the correct course of action. ARIN is meticulously gathering and logging all forensics associated with these attacks. The numbers are somewhat staggering as noted here in a recent attack:

Login Harvesting Attack Metrics
Invalid Password: 9,711
Invalid Captcha: 249,205
Invalid Username: 10,999,044

As you can see the attacks are extremely onerous and the amount of data associated with each attack makes it a challenge to identify the true aspirations of the people behind the attacks. We have developed much of the captured data and are currently in the process of analyzing it in order to develop and deploy deterrents to stop this. While we cannot go into specifics there is a significant amount of information captured in order to aid law enforcement agencies to become involved. 

    Are the attacked usernames targeted in any way, like associated with blocks
    that aren't currently in use?

(JS) Still unable to get to that level of detail but it does appear to be true.

    Maybe if the purpose of the attackers was clear, the security solution would
    be easier to consider.

(JS) ARIN has taken several measures to make these attempts less effective and we are currently coding additional safeguards such as the topic of this consultation. Rest assured that this is of the highest priority to ARIN.

    Hi Michael,

    That's single-factor: control of a phone number.

    AT&T defended itself from a lawsuit a year or two ago where someone lost
    millions of dollars of bitcoin because a hacker was able to get AT&T to
    activate a new phone with their phone number and then use that to reset the
    brokerage password. AT&T's position, which the court accepted, was that cell
    phone service was not advertised as or secured to a standard appropriate for
    authentication thus anyone who relied on it for such did so at their own
    risk.

    Regards,
    Bill Herrin
