When Your Sensible ID Card Reader Comes With Malware – Krebs on Safety

Thousands and thousands of U.S. authorities workers and contractors have been issued a safe good ID card that allows bodily entry to buildings and managed areas, and gives entry to authorities pc networks and techniques on the cardholder’s applicable safety degree. However many authorities workers aren’t issued an authorized card reader gadget that lets them use these playing cards at house or remotely, and so flip to low-cost readers they discover on-line. What might go fallacious? Right here’s one instance.

A pattern Frequent Entry Card (CAC). Picture:

KrebsOnSecurity just lately heard from a reader — we’ll name him “Mark” as a result of he wasn’t approved to talk to the press — who works in IT for a significant authorities protection contractor and was issued a Private Id Verification (PIV) authorities good card designed for civilian workers. Not having a wise card reader at house and missing any apparent steering from his co-workers on easy methods to get one, Mark opted to buy a $15 reader from Amazon that mentioned it was made to deal with U.S. authorities good playing cards.

The USB-based gadget Mark settled on is the primary outcome that at present comes up one when searches on for “PIV card reader.” The cardboard reader Mark purchased was bought by an organization known as Saicoo, whose sponsored Amazon itemizing advertises a “DOD Army USB Frequent Entry Card (CAC) Reader” and has greater than 11,700 principally constructive rankings.

The Frequent Entry Card (CAC) is the usual identification for lively responsibility uniformed service personnel, chosen reserve, DoD civilian workers, and eligible contractor personnel. It’s the principal card used to allow bodily entry to buildings and managed areas, and gives entry to DoD pc networks and techniques.

Mark mentioned when he acquired the reader and plugged it into his Home windows 10 PC, the working system complained that the gadget’s {hardware} drivers weren’t functioning correctly. Home windows urged consulting the seller’s web site for newer drivers.

So Mark went to the web site talked about on Saicoo’s packaging and located a ZIP file containing drivers for Linux, Mac OS and Home windows:

Out of an abundance of warning, Mark submitted Saicoo’s drivers file to, which concurrently scans any shared recordsdata with greater than 5 dozen antivirus and safety merchandise. Virustotal reported that some 43 completely different safety instruments detected the Saicoo drivers as malicious. The consensus appears to be that the ZIP file at present harbors a malware risk generally known as Ramnit, a reasonably frequent however harmful computer virus that spreads by appending itself to different recordsdata.


Ramnit is a well known and older risk — first surfacing greater than a decade in the past — nevertheless it has developed over time and is nonetheless employed in additional subtle knowledge exfiltration assaults. Amazon mentioned in a written assertion that it was investigating the experiences.

“Looks like a doubtlessly vital nationwide safety danger, contemplating that many finish customers might need elevated clearance ranges who’re utilizing PIV playing cards for safe entry,” Mark mentioned.

Mark mentioned he contacted Saicoo about their web site serving up malware, and acquired a response saying the corporate’s latest {hardware} didn’t require any further drivers. He mentioned Saicoo didn’t deal with his concern that the driving force package deal on its web site was bundled with malware.

In response to KrebsOnSecurity’s request for remark, Saicoo despatched a considerably much less reassuring reply.

“From the small print you provided, situation could in all probability brought on by your pc safety protection system because it appears not acknowledged our hardly ever used driver & detected it as malicious or a virus,” Saicoo’s assist crew wrote in an e-mail.

“Truly, it’s not carrying any virus as you may belief us, you probably have our reader available, please simply ignore it and proceed the set up steps,” the message continued. “When driver put in, this message will vanish out of sight. Don’t fear.”

Saicoo’s response to KrebsOnSecurity.

The difficulty with Saicoo’s apparently contaminated drivers could also be little greater than a case of a expertise firm having their web site hacked and responding poorly. Will Dormann, a vulnerability analyst at CERT/CC, wrote on Twitter that the executable recordsdata (.exe) within the Saicoo drivers ZIP file weren’t altered by the Ramnit malware — solely the included HTML recordsdata.

Dormann mentioned it’s dangerous sufficient that looking for gadget drivers on-line is without doubt one of the riskiest actions one can undertake on-line.

“Doing an online seek for drivers is a VERY harmful (when it comes to legit/malicious hit ratio) search to carry out, based mostly on outcomes of any time I’ve tried to do it,” Dormann added. “Mix that with the obvious due diligence of the seller outlined right here, and properly, it ain’t a reasonably image.”

However by all accounts, the potential assault floor right here is big, as many federal workers clearly will buy these readers from a myriad of on-line distributors when the necessity arises. Saicoo’s product listings, for instance, are replete with feedback from clients who self-state that they work at a federal company (and a number of other who reported issues putting in drivers).

A thread about Mark’s expertise on Twitter generated a robust response from a few of my followers, a lot of whom apparently work for the U.S. authorities in some capability and have government-issued CAC or PIV playing cards.

Two issues emerged clearly from that dialog. The primary was normal confusion about whether or not the U.S. authorities has any type of checklist of authorized distributors. It does. The Basic Companies Administration (GSA), the company which handles procurement for federal civilian businesses, maintains an inventory of authorized card reader distributors at (Saicoo just isn’t on that checklist). [Thanks to @MetaBiometrics and @shugenja for the link!]

The opposite theme that ran by way of the Twitter dialogue was the fact that many individuals discover shopping for off-the-shelf readers extra expedient than going by way of the GSA’s official procurement course of, whether or not it’s as a result of they had been by no means issued one or the reader they had been utilizing merely not labored or was misplaced they usually wanted one other one rapidly.

“Nearly each officer and NCO [non-commissioned officer] I do know within the Reserve Part has a CAC reader they purchased as a result of they needed to get to their DOD e-mail at house they usually’ve by no means been issued a laptop computer or a CAC reader,” mentioned David Dixon, an Military veteran and writer who lives in Northern Virginia. “When your boss tells you to test your e-mail at house and also you’re within the Nationwide Guard and you reside 2 hours from the closest [non-classified military network installation], what do you suppose goes to occur?”

Apparently, anybody asking on Twitter about easy methods to navigate buying the best good card reader and getting all of it to work correctly is invariably steered towards The web site is maintained by Michael Danberry, a adorned and retired Military veteran who launched the location in 2008 (its textual content and link-heavy design very a lot takes one again to that period of the Web and webpages typically). His web site has even been formally advisable by the Military (PDF). Mark shared emails displaying Saicoo itself recommends


“The Military Reserve began utilizing CAC logon in Could 2006,” Danberry wrote on his “About” web page. “I [once again] grew to become the ‘Go to man’ for my Military Reserve Heart and Minnesota. I believed Why cease there? I might use my web site and data of CAC and share it with you.”

Danberry didn’t reply to requests for an interview — little doubt as a result of he’s busy doing tech assist for the federal authorities. The pleasant message on Danberry’s voicemail instructs support-needing callers to go away detailed details about the difficulty they’re having with CAC/PIV card readers.

Dixon mentioned Danberry has “achieved extra to maintain the Military working and related than all of the G6s [Army Chief Information Officers] put collectively.”

In some ways, Mr. Danberry is the equal of that little recognized software program developer whose tiny open-sourced code mission finally ends up changing into extensively adopted and finally folded into the material of the Web.  I ponder if he ever imagined 15 years in the past that his web site would in the future develop into “essential infrastructure” for Uncle Sam?
