iSIGHT PARTNERS ANALYST COMMENT
The Premera Blue Cross breach was reportedly first discovered on January 29, 2015, two days after
Anthem, Inc. discovered it had been compromised by cyber espionage actors. The Anthem incident
leveraged Derusbi malware which communicated with the domain we11point.com (similar to Anthem’s
previous name, “WellPoint”). iSIGHT Partners has identified a suspicious domain, "prennera.com" which
is likely a spoof of Premera, and a malicious payload signed with the same digital certificate as malware
from the Anthem hack. The domain “prennera.com” was registered on December 9, 2013, and the
malicious payload identified was compiled December 7, 2013. Additionally, one sample related to the
Anthem compromise was compiled on December 20, 2013. The similarities in the timeline combined
with the usage of the same code signing certificate, suggests that the same threat actor was responsible
for both compromises.

SOUTH KOREA BLAMES NORTH KOREA FOR DECEMBER HACK ON NUCLEAR
OPERATOR
FROM THE MEDIA
South Korea has blamed North Korea for December cyber attacks against its nuclear
reactor operator. The cyber attacks were made between December 9 and 10 and
involved 5,986 phishing e-mails. According to South Korea’s investigation, the malware
used in the attack is the same malware (“kimsuky”) used by North Korean hackers.

iSIGHT PARTNERS ANALYST COMMENT
iSIGHT Partners reported on suspected Chinese cyber espionage actors targeting KHNP in December
2014, utilizing PH_King malware. However, the posting of allegedly exfiltrated documents online and
demanding ransom is inconsistent with such actors and may suggest KHNP was successfully targeted by
multiple groups within the same timeframe. If the actors responsible are carrying out intrusions in
alignment with North Korean state policy, further activity may focus on targets of the current North
Korean regime.

MICROSOFT WARNS OF FAKE SSL CERTIFICATE FOR WINDOWS LIVE
FROM THE MEDIA
Microsoft has issued a warning that an SSL certificate for the website, “live.fi” has
been improperly issued and that it could be used to spoof content and conduct manin-the-middle attacks. Allegedly, all versions of Microsoft Windows operating systems
are vulnerable. The fake certificate has been revoked by the certificate authority.

iSIGHT PARTNERS ANALYST COMMENT
The improperly issued SSL certificate for live.fi has been revoked, and we have no reason to believe that
it has been employed by malicious actors to date. While systems that do not employ automatic updates
(or manually apply update 2917500) may be at risk from this certificate, we suggest the more
concerning aspect of this incident for most enterprise environments is the overall security surrounding
the issuance of certificates.

ADVANTAGE DENTAL REPORTS HACKER BREACH
FROM THE MEDIA
Advantage Dental has indicated that unnamed actors gained unauthorized access to
its systems between February 23 and 26, resulting in the compromise of over 150,000
patients’ records. The company has notified the affected individuals and indicated
that patients’ names, Social Security numbers and home addresses, among other
information, was compromised.

iSIGHT PARTNERS ANALYST COMMENT
Advantage Dental is an Oregon-based dental practice, with more than 20 clinics. Although not a major
breach like those of national retailers, the compromise of 150,000 records will likely enable cyber
criminals to conduct numerous types of fraud, most probably spamming and identity theft. Advantage
Dental was likely an opportunistic compromise. Cybercrime actors often utilize spam services to broadly
target as many potential victims as possible, increasing the likelihood that the infected victims are
valuable targets, such as Advantage Dental.

RESEARCHERS FIND SAME RSA ENCRYPTION KEY USED 28,000 TIMES
FROM THE MEDIA
More than two weeks after the FREAK flaw was released, 2.2 million hosts are still
accepting 512-bit encryption keys, according to researchers at the University of
London. The researchers also found that 28,394 routers running SSL VPN use the same
512-bit public RSA key. It is possible that the manufacturers involved generated one
key and installed it on many devices.

iSIGHT PARTNERS ANALYST COMMENT
Because it improves the ease of exploitation for malicious actors, re-use of keys drastically reduces the
security of cryptographic implementations. Weak cryptography and poor encryption implementation
can severely undermine SSL implementations. A vendor fix is available for the FREAK flaw that would
prevent exploitation of this issue. At this point, iSIGHT Partners is unaware whether malicious actors are
targeting vulnerable networks relying on with these re-used keys.

GOOGLE APP STORE GETS MORE OVERSIGHT
FROM THE MEDIA
Google apps are now being screened by a new Google team for malware and sexually
explicit material. Additionally, Google will be tightening their age-based rating system.
Prior to this system, Google only used an automated system to screen new apps.
Furthermore, developers will now have to answer special questions to help determine
the age based ratings.

iSIGHT PARTNERS ANALYST COMMENT
This development will almost certainly contribute to a safer Google Android marketplace. iSIGHT
Partners has previously observed malicious apps available in the Google app store that have bypassed
the marketplace's security checks. The human reviewers will be better able to detect emerging
techniques for evading automatic security scans, such as the use of packers to defeat static analysis.
However, this development may not affect malware that is already hosted in Google Play, as indicated
by the continued presence of previously observed malware.
