What do ASD Essential Eight changes mean for your organisation’s security

 

By Alex Duffy, Security Solutions Architect, emt Distribution 

The recent (25/2/19) and unexpected update to the Australian Signals Directorate’s Essential Eight Maturity Model serves to keep the ASD’s guidelines relevant going forward and address the latest weak points in IT security. What stays the same though is the ASD’s guidance on practical updates on how to stay ahead.

 

While these guidelines are specifically relevant to federal government organisations’ critical infrastructure they are now being pushed indirectly to contractors or businesses who work with the federal government. But even though these guidelines may not be mandatory for private businesses, they are best practice. If they are good enough to safeguard our political, defence and economic interests as a nation, they should be appropriate to safeguard our businesses from the majority of possible cyber security attacks and incidents.

 

This recent update sees fewer restrictions around patching but a higher level of control on Application Whitelisting which has now been extended to all workstations for levels 1 and 2 of the maturity models. Multi Factor Authentication no longer permits the use of SMS, emails or voicemails for level 1 maturity and specifically states a requirement for passwords to be longer than six characters at all levels.

 

But what does this actually mean for today’s IT professionals?

 

These changes reflect the changing priorities required to address today’s threat landscape. With the loosening of controls around patching, the ASD acknowledges the balancing act that security personnel must perform in certain environments. There is definite acknowledgement of the dilemma faced where patching may break functionality vs maintaining a secure environment and strict adherence. A reduction in the burden on already overworked IT admins meeting requirements while allowing better automation is removing overhead while not reducing security.

 

The higher importance placed on Application Whitelisting definitely reflects what we see in the marketplace. With Application Whitelisting now available as a mature solution it is reasonable to expect organisations to use it across their entire environment. Increased visibility alone of endpoint applications makes life easier for security, helpdesk and management alike stopping more endpoint threats before they reach any part of the network.

 

Combined focus on patch automation and increased scope of Application Whitelisting we also see as acknowledgement of a more distributed workforce need for security and higher difficulty in controlling remote endpoints.

 

The more specific wording for Multi Factor Authentication also recognises how threat actors are now working around basic MFA and endeavours to close those weak spots.

 

There are now only three maturity levels instead of the original five: Partly (level 1), Mostly (level 2) and Fully (level 3) aligned. Level 0 is no longer listed as it doesn’t meet even the most minimal criteria and level 4 is only required on an ad hoc basis depending on advice from the ASD. These changes assume that organisations will now at least begin to adhere to these standards to a degree and give a clear path to full alignment at level 3.

 

The biggest takeaway from this update appears to be that it is no longer reasonable for a business entity to not address the Essential Eight, especially with the removal of level 0. If a business has not yet met the criteria for level 1 then its current security measures are faulty and need immediate remediation.

We welcome this specific update because it reflects what our customers have been demanding already. emt’s focus on security solutions addresses the Essential Eight and beyond to ensure our customers’ networks are ahead of requirements using the latest technologies. We already have solutions that address the Top 4 – Airlock Digital, Flexera, Stealthbits, and Thycotic.

Flashpoint Intelligence on APAC-ANZ Cyber Activity to Guide Upcoming Risk Decisions

Author:  Aaron Shraberg, Flashpoint

 

Geopolitical and economic tensions between the United States, China, and North Korea figure to steer risk management decisions in the Asia-Pacific region for the coming months. Organisations, such as some recently targeted financial services institutions in Australia and New Zealand, should closely monitor cyber and political activity in the area.

The diverse geopolitical and economic interests of the states in the region play a significant role in driving and shaping cyber threat activity against entities operating in APAC. While most threat actors targeting organisations in the region are financially motivated, nation-state activity remains a potent threat against government and diplomatic entities, as well as financial organisations as nations such as North Korea continue to fund operations through hacking.

Political and Economic Events to Watch

As 2019 progresses, the ongoing trade conflict between the U.S. and China could spur an uptick in cyber activity against the U.S. and its closest Five Eyes allies, further eroding the Xi-Obama agreement to cease China’s industrial espionage activity for economic gain.

Last year, a limited number of named APT outfits operating in the region were alleged to be behind high-profile compromises and thefts of data and/or funds from global financial institutions, attacks on various multinational firms via third-party providers, and campaigns against the cryptocurrency industry.

North Korea is likely to remain a stressor in the region. It is unlikely to unilaterally disarm its nuclear program, and will likely ramp up its cyberattacks against APAC, ANZ, and Western financial institutions, as well as cryptocurrency exchanges in order to finance the regime and its activities. Organisations should also monitor unresolved disputes over ownership and militarisation of parts of the South China Sea, debates over the integrity of Huawei and ZTE devices in Western networks, and other events in the region that could impact businesses in ANZ and APAC.

While some criminal organisations operating in ANZ and APAC are believed to be behind Eastern European outfits in terms of experience and capabilities, APT activity from China and North Korea is considered highly advanced. Organizations in the region should be aware of campaigns linked to criminal or nation-states in the area, and some of the tactics, techniques, and procedures (TTPs) employed by these groups.

Advanced TTPs Coming out of APAC-ANZ

Some TTPs include commonplace first-stage attacks such as phishing or spear-phishing emails and watering hole attacks. These groups also have at their disposal banking Trojans, malware that seeks out and steals credentials, and ransomware, among others. Many criminal groups are proficient in activity to facilitate carding and reshipment fraud, the theft and sale of personally identifiable information, as well as more technically involved operations, including the sale of compromised RDP hosts, developing proxy and anonymization tools (to circumvent law enforcement and censorship efforts), and other tactics to carry out fraud.

Some attackers are also making use of publicly available exploits for common vulnerabilities in Apache Struts, Oracle products, Adobe Flash, Microsoft Office and others. Most of these vulnerabilities have already been publicly disclosed and patches are available, meaning that threat actors are opportunistic in the region, capitalising on lax patching efforts, or under-resourced IT organizations to exploit these security flaws.

Already this year, financial institutions in Australia, Japan, and elsewhere have reported being targeted by a new spam campaign using the Hancitor dropper to infect machines with the Gozi information-stealing malware. Gozi, also known as Ursnif, packages up banking and other account credentials from an infected machine and exfiltrates them to an attacker-controlled server. Variants of the banking malware have been active since 2014 and frequently target Microsoft Office vulnerabilities to gain a foothold on unpatched machines.

Malware-based attacks aren’t the only means of profit for threat actors in the region. Late last year, several Chinese-language Deep & Dark Web forums contained posts advertising the availability of fraudulent identification cards from Australia, New Zealand, several locations in Europe, as well as North America. The fraudulent documents would allow, in some regions, the ability to travel without additional visas, vote in elections, or open bank accounts, for example. Another post also advertised processing of identifications and passports from Australia, New Zealand, Canada, France and Germany, opening the door to citizenship in some of those locations, in addition to the previously mentioned capabilities.

Assessment

Enterprises in Asia-Pacific, Australia, and New Zealand will have impending risk management decisions guided in some part by the fragile geopolitical and cyber climate in the region. As the U.S., China, and North Korea tug at each other’s shirttails in cyberspace and in the political arena, businesses will continue to be targeted by criminal and state-sponsored outfits operating in APAC and ANZ. Any erosion of these diplomatic or economic relationships will trickle down to businesses in the area, and threat activity targeting countries and companies in APAC-ANZ will be influenced accordingly.
