So, without
dampening the Christmas Spirit (too much), what does 2019 potentially have in
store for us? What can organisations do pre-emptively to reduce the likelihood
and impact of a cyber-attack? Here are my top 5 predictions for 2019;
1. More Third Party Applications / Code Libraries will be
targeted.
Organisations
focus on protecting their own critical assets with significant investments in
resources and technologies, but then either give access (or share critical
data) with third parties who are not as mature. In 2018, we've seen some
examples where Open-Source or third-party integrations have been abused by
attackers, with Magecart’s JavaScript injection being a primary example. With
API abuse to steal authentication tokens also on the rise, the impact of this
attack can be significant, not only exposing client / customer data, but
potentially the entire supply chain, similar to the recent Facebook breach. In
2019, I predict that this will be the vector of choice for a few reasons;
1) Many
organisations don't conduct regular security reviews on their supply chain, let
alone review the impact of using third-party code libraries and integrations.
2) These attacks
are easy to scale and are therefore cost effective for attackers.
3) The yields
and likelihood of selling off or sharing the techniques to other groups is also
very high, again making this a profitable exercise.
2. Business Email
Compromise attacks will evolve.
In 2018,
ZeroDayLab saw a significant increase in not only the intensity of business
email compromise campaigns, but the sophistication used by attackers. In the
last Quarter of 2018, attackers were using more advanced techniques to
compromise supply chain mailboxes to harvest invoices and other information,
usually to craft highly convincing phishing emails that either deliver malware
aim to defraud their target out of funds. These attacks, although not new, have
adapted as awareness of Whaling (CEO Scamming), has matured, but the techniques
witnessed in Q4 2018 will proliferate in 2019, and catch unsuspecting
organisations off guard.
3. Crime-as-a-service
will be a driving factor behind many attacks.
After high
profile Global Ransomware attacks such as NotPetya and Wannacry, it seems in
2018, Ransomware attacks have dropped off the face of the earth, mainly due to
awareness, volatility in crypto currencies, and increased attention from law
enforcement. However, bucking the downward trend is ransomware-as-a-service
offerings such as “GandCrab”, which have both seen an upturn in
infections, and maturity of the offering to their criminal consumers, with
reported ill-gotten gains in the millions.
Crime-as-a-service
has all but removed the barrier to entry to cyber-crime, with
hacking-as-a-service, malware / ransomware-as-a-service and now
phishing-as-a-service featuring highly on the Dark Web and Telegram; these
platforms provide even the most novice of criminals the ability to target
relatively mature organisations with some level of success. This trend is only
going to rise in 2019.
4. Lack of visibility
will be punished
There are a few
things that the recent Marriot breach has taught us: blind spots can be
punishing, attackers are constantly looking for ways to compromise assets that
organisations have no visibility of, or even worse, are not in an asset register
and therefore have no idea of its existence. The rise of Shadow IT, where
solutions and technology are purchased without the knowledge of IT / Information
Security, provides attackers a target where in most cases there is no
protection or monitoring for unauthorised access. This opportunity allows the
attacker to potentially pivot on to a more critical system, or in worst case
scenarios, actual access to personal information.
In both cases,
these are an easy attack surface with significant oversight. Attackers
constantly use tools like Shodan and Censys to discover public facing assets
with default / weak passwords, weak encryption, or any of the critical risks
found within the OWASP Top Ten; these are quick wins for attackers and deal a
devastating blow to organisations with a huge impact to reputation, and usually
catch the information security team off guard.
5. Cloud Security
Misconfiguration
Although great
strides have been made to improve the security of critical assets in the cloud,
organisations still haven’t fully embraced the protection available, or worse,
have misconfigured environments allowing attackers to capitalise on this. There
have been many incidents in 2018 that highlighted this: open S3 buckets with
vast amounts of customer data unencrypted and available to anyone, weak admin
credentials with no MFA, private keys posted in GitHub repositories, the list
goes on. Human error is a factor that the cloud sadly won’t fix, only expedite,
with significant consequences for organisations that don’t embrace the Sec in ‘DevSecOps’!
With increased Governance around the protection of the Privacy and Security of
PII (Personal Identifiable Information), those fully adopting the benefits of
the cloud also need to fully enforce the security controls.
There is some
good news, however; there are many things organisations can do to reduce the
impact of the aforementioned security risks;
- Ensure Asset registers are fully up to date and include any cloud-based applications and systems within these. In addition, ensure they are patched to the latest version, or highlight the risk for those that cannot be, with the relevant justifications and mitigation. This seems simple, but the volume of organisations that don’t have a fully up to date and relevant register is significant.
- Conduct regular Ethical Hacking Assessments on your risky assets, especially those that are public facing. Check cloud and internal networks for misconfiguration - the quickest win to prevent abuse from attackers. Also test those integrations; understand how and where you are exposed.
- Train Developers and Operational teams (DevOps) on secure coding and deployment principles. Ensure these are documented through a defined set of procedures and policies. Also ensure developers are using secure coding frameworks, and not using risky third party libraries, or untested open-source object.
- Conduct regular BIA (Business Impact Assessments), to help define critical assets, and ensure they have the relevant controls in place - essentially find your blind spots and fix them!
- Conduct Supplier Evaluation Risk Assessments regularly, understand the security maturity of your critical suppliers, and act to address those that expose you to unnecessary risk.
By conducting
the above activities in 2019, you’ll not only reduce the risk to your
critical assets, but also have the appropriate intelligence to develop a
strategy moving forward.
