[Eril-l] American Chemical Society blocked IPs

[Bob Pearson]

Hi Matthew

When using UsageLimit, what settings do you use for “MB” and “transfers” and do you have specific settings for ACS?

Noelle,

If you haven’t already looked in to it, you may want to consider the UsageLimit option:

Noelle,

Thanks so much for sharing this information. We got a report from ACS of a breach via our proxy server and investigated as we do normally. We identified a compromised user account and reported back to ACS but they have not been responding to our requests to have the block removed.  Now I know why.

-Kathleen

Hi All,

Here at Drexel we had a hack of 4 users account on Sunday, and the accounts were used to download massive numbers of articles from ACS.  ACS subsequently blocked our access through our EZProxy IP address.

I just got off the phone with Richard at ACS about this, who let me know that many universities had user accounts hacked in the same way, and this breach was affecting several other publishers as well.   I was surprised I hadn’t seen any traffic about the issue on this listserv – has anyone else been blocked by ACS or another publisher in the last few days for excessive downloading?

FYI – ACS says they are not unblocking any IP addresses until they have the issue resolved, at which time they’ll email all their affected customers about reinstated access.

Thanks, Noelle
