Colleagues,
Chinese researchers at Qihoo 360
have discovered an RCE (remote
code execution) vulnerability in Blockchain EOS when
using smart contracts. This bug potentially
allows hackers to take complete control over node servers. Commonly referred to as Blockchain 3.0, EOS
is an open source platform smart contracts. The RCE flaw is considered by some
to be a 51% attack.
Bottom line question: How vulnerable are node servers on a Blockchain to the
RCE bug? Specific mitigation methods are rather illusive. However, CSD
recommends your review of “Bug
Characteristics in Blockchain Systems: A Large Scale Empirical Study”
published by the Singapore
Management University. Share your

How Secure is AWS Authentication when using Google’s identity service for user identification?
Colleagues,
Amazon Cognito can provide
authentication, authorization, and user management for AWS users of mobile
apps. This process involves a better
understanding of federated authentication mechanism, a simplified credential
management for teams who already have Google
accounts, Customize authentication mechanisms at very low maintenance costs
while serving as a good alternative to deploying and configuring our own IDP
service Codecentric
recommends a three step process: First, build a simple web service using AWS API Gateway and AWS Lambda. Second,
use AWS IAM is the AWS service for access control. And third, employ using the AWS
Secure Token Service together with Google Sign-In. Given the
significant growth of both Amazon AWS customers who also use Google’s identity
service the critical question is just how secure is this process? Without doubt
both vendors systems are highly secure, however we are less certain about the
security and viability of using the two disparate system in tandem.

VPNFilter Router Malware Attack – Is Russia Up to its Common Tactics?
Colleagues,
the US FBI and DHS along with the UK’s National Cyber
Security Center jointly warned that hackers working on behalf of the Russian
government are compromising
large numbers of routers, switches, and other network devices .
Code-named VPNFilter, this malware
has primarily targeted some 500,000 consumer and small business router
worldwide … yet with a geographic focus on the Ukraine. Sound suspicious? It
contains the RC4 encryption
cipher BlackEnergy.
BlackEnergy has been used
in a variety of attacks tied to the Russian government. The type of devices
targeted by this actor are difficult to defend. Most of the impacted routers
are on the perimeter of the network with no IPS and commonly without do not
have an AV package. Read the Cisco Talos
security report by clicking here. So who is behind VPNFilter? CSD supports the
Russian origin theory. What about you? Share a comment and subscribe today!

How Serious is the ZipperDown iOS App Programming Vulnerability?
Colleagues,
China-based jailbreaker Pangu Labs has identified a vulnerability which they project impacts some 9.5%
of the 168k Apple iOS apps may have. The root cause appears to be an app programming error that can lead
to code execution and data overwritten in the affected apps." Some
of the more noteworthy iOS apps impacted include but not limited to QQ Music, MOMO, Weibo, Kwai and NetEase
Music. The ZipperDown web site provides a good FAQ yet is short on mitigation
details. Bottom line: How far reaching are the consequences of ZipperDown? And is there a comparable bug in Android apps?
Details to follow. For now, share a comment and subscribe today! Lawrence, Cyber Security Defender (https://cybersecuritydefender.blogspot.com)

RSA Conference’s Cybersecurity Tech Accord – Substance or Delusion?
Colleagues,
during last month’s RSA Conference
34 tech companies including Microsoft, Facebook, HPE, ABB, Arm, Cisco, Nokia, Oracle, and
Trend Micro announced a Cybersecurity Tech Accord (aka Digital
Geneva Convention) pledging to mount a united effort against state-sponsored
cybercrime and warfare. Notable abstentions included Amazon, Alphabet and
Apple. According to Juniper
Research cybersecurity attacks on organizations and commercial
entities is expected to
reach an $8 trillion impact by 2022. The essence of the Accord is a
four-fold commitment to: 1) Share
threats and minimize the potential for malicious code to be introduced into
cyberspace, 2) Protect all customers globally regardless of the motivation of
the attack, 3) Will not help governments launch cyberattacks against innocent
citizens, and 4) Empower users to make effective use of their products with new
security practices and new features. Here at CSD applaud this move …
particularly in light of increased cyber threats from Russia, Iran, North Korea
and non-state bad actors. Bottom line: Will the four-fold commitment of the
Accord be fulfilled in concrete deeds not just words on a signed piece of paper
to appease the public and free-democratic governments? Share a

“Roaming Mantis” – Assessing the Impact of Android Malware on Users
Colleagues, rapid evolution, cryptojacking, global scope, mobility and
DNS hijacking. These are the traits of a Tier 1 malware threat to the 2
billion+ Android-based devices across the world and Roaming Mantis appears to have them all. This voracious malware was first identified in in Japan
during March 2018 when infected routers began redirecting users to compromised
websites. Roaming Mantis
currently supports 27 different languages and has expanded to users on four
continents. This new version contains a script for the popular cryptocurrency
miner Coinhive and the capability to target iOS devices in addition to
Android devices. What are
the most effective mitigation techniques? Security
Affairs focuses on mitigation beginning with securing routers, using up-to-date
firmware, enforcing strong passwords for admin access and disabling remote
access to the administration interfaces on the routers. This attack targets DNS
services running on routers. A DNS service running on a server inside your
network is not at risk to this attack. And only install software from trusted
app stores such as Google Play and the Apple App Store. We also recommend the SecureList’s
APT Mitigation in-depth checklist. Comment

Syrian Electric Army Delivers Cyber Attacks to Defend Bashar al-Assad
Colleagues, while the SEA does not have the statute of their counterparts in
Russia, Iran or North Korea, it represents a formidable cyber warfare threat to
opponents of Bashar al-Assad including the US, Israel and Western
European nations. In fact three of its members have made their way onto the US FBI’s
Cyber Most Wanted List. The group gained initial attention in 2011 and since then
has conducted attacks with ideological motives. Their tactics include DDoS attacks, DNS hijacking, launching
fraudulent fabricating Facebook and YouTube sites, spear-phishing and Web site
defacement. The rampant civil war in Syrian combined with the presence of US
and NATO forces has served to fuel the fire for SEA. They are behind the
defacement of the US
Army’s public web site, a hack of the LinkedIn
portal and the RSA
(Security) Conference site. Bottom line: Although SEA does not have the prowess
of its tier 1 peers in North Korean, Iran and Russia, it must be taken
seriously and we support all appropriate proactive counter-measures to undermine
this cyber enemy. Comment and

North Korean Proxy the Lazarus Group’s Malware Suspected to go beyond Central American casinos
Colleagues, financial gain
appears to be the root cause motive behind the recent Lazarus Group’s (or Hidden
Cobra) malware attacks on casinos in Central America, a bank in Bangladesh and
potentially of the soft targets. This is the same entity suspected of the 2016 cyber-attacks
again US-base Sony Pictures. KillDisk is a
standard detection name that ESET uses
for destructive malware with disk wiping capabilities and helped detect Win32/NukeSped
and Win64/NukeSped
attacks. The number of systems affected and financial loss to such malware has
not been well quantified. How can KillDisk be mitigated? A comprehensive silver
bullet solution is unknown the Cyber Security Defender recommends a careful
review of the Australian Government’s Department of Defence publication
entitled Strategies
to Mitigate Cyber Security Incidents. What is the Lazarus Group’s next
target? Share your comments and subscribe today! Lawrence, Cyber Security Defender

The Cyber Threat Within: US FBI Identifies “Vault 7” Attack Suspect at the CIA tied to WikiLeaks
Colleagues, former US CIA
cyber expert Joshua Adam
Schulte is the FBI’s prime suspect in releasing top secret cyber
methods and measures to WikiLeaks in 2016.
Schulte is in custody in NYC. Schulte is charges with distribution of national defense information including computer code designed to take over iPhones and
convert smart televisions into surveillance devices. It appears that Schulte
follows in the footsteps of Americans Jonathan
Pollard, Edward Snowden and WikiLeaks Australian founder Julian
Assange. Aside from the fact that he was labeled as a
“disgruntled employee” at the CIA its remains to
be seen what motivated Schulte. Bottom line: Despite advanced human factors,
cyber security software and profiling, governmental and private sector entities
alike must remain increasingly vigilant against the potentially treasonous acts
of employees and third party contractors. Further resources must be devoted to
mitigating and preventing internal threats. Share your

Can We Expect Iran to Launch Cyber Attacks in Retaliation for the US Revoking the Nuclear Arms Agreement?
Colleagues, anger,
outrage and retribution lye at the heart of Iran’s response to the US’ withdraw
from the JCPOA
agreement on May 9, 2018. As such we predict Iran, possibly aided by Russia,
will unleash a new round of cyber security attacks against US interests in
North America and abroad. The Iranian government has been accused by western analysts of its own
cyber-attacks against the United
States, Israel and Persian
Gulf Arab countries. Like its allies Russia and North Korea, it
is widely believed that Iran has heavily invested to strengthen its offensive
cyber capabilities such as the Iran
Hackers Sabotage. Israel’s Institute
for National Security Studies (INSS) purports
that Iran is "one of the most active players in the international cyber
arena". So what to expect? Our view is that Iran will seek out soft cyber
targets in the US communications, financial and energy sectors. But for Iran
the real prize would be an attack on a US federal government or military
installation with the goal of sending a clear “political” message to the Trump
administration. Share your comments and subscribe today! Lawrence, Cyber Security Defender
