Justice Department investigates Sci-Hub
founder on suspicion of working for Russian

A story in today’s Washington Post reports that the Justice Department has launched an investigation – with both criminal and intelligence-gathering elements – into Sci-Hub’s founder, Alexandra Elbakyan. The article says that a former senior U.S. intelligence official said he believes Elbakyan is working with Russia’s military intelligence arm.

This confirms our worst fears. At PSI we’ve been investigating Sci-Hub for three years. It was inconceivable that

Elbakyan, all on her own, could have funded and run a site the size of Sci-Hub, containing 76 million articles and providing 200 million annual downloads. We have been warning of the risks presented by Sci-Hub for some time, for example here.

From our research with academic institutions and publishers over the past three years, we discovered the scale and scope of the phishing at western universities to obtain the credentials has been truly industrial. We found that Sci-Hub had stolen log-in credentials for 373 universities in 39 countries, including more than 150 academic institutions in America alone. Leading research nations with a high number of compromised university systems include the UK, Canada, Australia and Sweden as well as technical universities in Germany.

The vulnerability of universities to cyber-crime has been apparent for some time and the authorities have been warning about the risks to such institutions in the US and the UK.

Following the Washington Post’s revelations about Alexandra Elbakyan, the question now is what actions should universities take to protect their intellectual property, their faculty and their students?

As a matter of urgency, here are some simple and immediate steps that can be taken to enhance your current security:

  • Block access to Sci-Hub. Make your users aware that by attempting to download content from these illegal and dangerous sites, they are putting their university at risk. 

  • You can block access to these illegal sites by downloading the Outgoing Block List from

  • Download the Incoming Block List from (your academic library staff should already have access to this resource) and protect your university from harmful intrusions by Russian Military Intelligence.

  • Finally, universities must share information with each other about the source of attacks, so that they and other organisations can start to protect themselves and each other.

Please get in touch if you’d like to hear more about any of the issues raised in this letter.

Kind regards,

LibLynx & PSI  partner on real-time
Open Access Usage Reporting

Alexandria, VA - Liblynx and PSI partner to deliver real time usage metrics to organisations wanting to learn who is accessing their Open Access (OA) content.


As the volume of OA content increases, it’s becoming increasingly crucial for OA publishers to know who is reading their content and where that readership is based, especially when developing new transformative deals and providing metrics to funders.  Traditional methods of usage reporting that rely on authenticating user access do not apply to OA content.


The new OA Usage Reporting solution works by capturing and analysing raw usage data from a publisher’s platform.  The organisational source of usage is identified by matching incoming IP addresses against PSI’s to provide organisational detail of users and geographical data for all remote use.  The analysis can also identify malicious access, such as Sci-Hub downloads, by matching data to PSI’s database.


OA usage reports will be available by title, source organisation, organisation type, and geographical location.  Reports can be viewed online or downloaded from any existing website by embedding the LibLynx reporting widget. Alternatively, reports can be delivered as a data feed for ingestion into a third party analytics tool.  Libraries and other information and knowledge managers will be able to access organisational usage data directly from their profile on


Andrew Pitts of PSI said, “Working closely with publishers, membership societies and libraries for many years has enabled PSI to create a powerful database that can be leveraged to provide publishers, libraries and authors with valuable data to nurture a deeper understanding of organisational readership.


Traditional usage reporting tools are slow, inflexible, and expensive to implement and maintain,” said Tim Lloyd, CEO of LibLynx.  “Our lightweight solution is much simpler to implement and delivers near-real time analytics that publishers can flexibly integrate with their existing workflows.


Publishers interested in learning more should contact either party for more information.

Important new EZproxy security feature calls out to PSI’s blocklist for validation


We are delighted to announce that OCLC is using PSI’s IP Intrusion Service block list to provide a new security feature for their latest release. EZproxy 6.5 contains an important feature that incorporates a real-time call out to a security API that validates the IP address of the requester and logs/denies access if the IP address is a known pirate/hacker. This greatly reduces the time-consuming and manual process of scanning log files for hacked credentials. The API calls out to a blocklist created by and validated via is a repository that contains over 1.5 billion verified IP addresses from 60,000 content licensing organizations worldwide. Both and are maintained by PSI Ltd.

The IPs on the list have been identified as the source of spamming, phishing, hacking, and other forms of cyber-crime. The list also incorporates the information identified on the P.R. Butler list. One major advantage of this blocklist is that it uses as a whitelist, giving libraries the power to ensure that their verified IP addresses are not included on the list. Keeping the IP addresses held within for your organisation up-to-date will ensure that these IPs are never included on the block list. We urge all libraries that haven’t already done so to register a user and confirm the IPs held for their organisation.


PSI is an independent third-party organization, which enables libraries, publishers and membership societies to work together securely and confidentially towards the common goals of facilitating legitimate access to scholarly content, eradicating IP misuse, eliminating subscription abuse, and combating cyber-crime.

OCLC is a non-profit global library cooperative providing shared technology services, original research and community programs so that libraries can better fuel learning, research and innovation.

SiQ and PSI Partner for Reporting the Great Unknown

SiQ and PSI Integrate COUNTER Analytics with IP Registry to Resolve Unknown Usage Issues

San Antionio, TX: SiQ and PSI are delighted to release a new integration of IP Registry data to COUNTER and publisher usage reporting and analytics, significantly resolving the issue in attributing institutional usage to unknown or expired sets of IP ranges.

Usage metrics are some of the most trusted and common measurements used to demonstrate the value relationship between authors, publishers, funders, librarians and researchers, however the provision of such measurements relies on the availability of associated data to match the usage to institutions. This is particularly challenging for Open Access publishers, repositories and for ‘Unknown’ usage where the publisher does not have database entries to match usage identifiers to identifiable institutions.

SiQ, leaders in providing COUNTER compliant usage reporting for over 15 years, has partnered with PSI to overcome this challenge and deliver COUNTER R5 reporting using PSI’s IP Registry database to assign institutional usage by IP address. is the only pre-populated IP Registry containing over 1.5 Billion fully vetted and verified IP addresses for over 60,000 libraries. contains data from over 170 publishers and has been tested by libraries all around the world.

“This collaboration between SiQ and PSI provides enormous potential for all publishers to attribute usage to, and understand engagement with previously unidentifiable accounts. The combination of PSI’s unrivalled dataset and SiQ’s analytics services will transform how publishers identify opportunities and deliver new evidence based acquisition programs.” Stuart Maxwell, VP, SiQ.

The service integrates data with COUNTER compliant usage data to enable reporting and analysis for previously unidentifiable institutions. These reports are delivered in the next generation of COUNTER 5 standard reporting, and via flexible publisher analytics to support internal business intelligence to report trusted, valued data and insight to further business stakeholders. The underlying business intelligence analytics provides click-level usage data that is configurable for reporting against any and all available dimensions including article, item, author, funder, source, topic, location, technical etc as well as attribution to institutional data in the IP Registry.

The COUNTER standard is recognised as the trusted, comparable, independent currency for usage reporting and SiQ has been supporting publishers in meeting these requirements and more since the inception of COUNTER. In addition to providing publishers with reporting supported by this official stamp of trust, including through independent audit, SiQ makes this data available throughout their organisation and to other stakeholders so that insights and decisions can be made on accountable and consistent data.

STM announces endorsement for compliance with anti-bribery and corruption legislation

  • Anti-bribery and corruption principles released to assist Members

  • Publisher Solutions International selected to lead voluntary compliance scheme 

The UK Bribery Act of 2010 contains a number of important provisions which are relevant and important for the publishing industry – specifically it relates to the process of appointing and maintaining relationships with subscription agents and intermediaries. Similarly, recent efforts to enforce related regulatory efforts around the world such as the US Foreign Corrupt Practices Act and OECD’s 2009 Anti-Bribery Recommendations have increased the visibility of anti-bribery and corruption matters and underscore the risks of not implementing robust anti-bribery and corruption policies.     The International Association of Scientific, Technical, and Medical Publishers (STM) has released a set of principles designed to assist publishers in their efforts to ensure compliance with the UK Bribery Act and related legislation.   
As part of this wider effort to present publishers with a viable means of complying with important aspects of the Act, STM has also recently completed a ‘Request For Proposal’ process whereby several independent companies were asked to present proposals for the services of a Due Diligence Bureau to assist participating publishers in a voluntary scheme with compliance with the anti-bribery and corruption legislation around the world. Following this process, STM has recommended Publisher Solutions International, Ltd (PSI) as part of a voluntary compliance mechanism for its members.  
Accordingly, PSI has been invited to begin the process of communicating with members of STM in an effort to gauge interest within the marketplace for such a program.  PSI will be working closely with STM and the Association of Subscription Agents (ASA) with the goal of enlisting sufficient participation to warrant launching a global compliance program in January of 2015.  
The Due Diligence Bureau program will consist of several facets including: 

  • Compliance questionnaire/survey for all active intermediaries

  • Research via independent diligence databases

  • Local news service audits

  • Credit check/ratings audit 

As part of the program, PSI will conduct an ongoing review of active intermediaries for all participating publishers and will house and provide access to the results of same via a protected database.
