I Wannacry over Petya

News >>

Just as our businesses avoided or got over WannaCry, the name given to the recent Ransom\ware, there's a new attack following close behind. It appears it is exploiting the same vulnerability as Wannacry. The malware responsible is widely thought to be a version of Petya. This latest  ransomware has already crippled Ukrainian government departments, banks, power distributors and transport networks. Now apparently it has spread to other high-profile victims such as a British advertising firm, a French construction materials giant and one of the largest pharmaceutical companies in the world. Australia is unlikely to avoid it this time, with Cadburys and TNT having announced they have fallen victim. the Australian staff of DLA Piper, a global law firm, has apparently been locked out of IT systems after Petya impacted one of its overseas offices.  

The ransomware continues to spread and it’s far from over. The Assistant Minister for cyber-security Dan Tehan is calling the fresh attack a "wake-up call" and the Prime Minister's cyber security advisor Alastair MacGibbon has warned against paying ransoms for Petya, urging businesses to instead back up their data to "avoid being a victim in the first place".

So it is now time for you to manage this risk effectively.


Start with technology solutions
While technology is not the only solution, it is an important component. The Australian Cyber Security Centre recommends that organisations take the following steps:

  • Update all your systems immediately, including Microsoft operating systems. Using unpatched and unsupported software increases the risk of cyber security threats such as ransomware.
  • Back-up your data. If you do not have back-ups in place you can arrange to use an off-site backup service (the Cloud). This is good practice for all users.
  • Make sure your antivirus software is up-to-date.

Policies, plans and procedures
 Make sure existing policies in relation to email and internet usage, password protection and the use of mobile devices, are up to date.  Remind all users of the risks of opening email attachments received from unknown or suspicious sources. Organisations should also revisit their cyber incident response plans in the aftermath of Petya.

What if I am impacted?
The Prime Minister's cyber security advisor and the Australian Cyber Security Centre warn that individuals and organisations should not pay the ransom. There are widespread reports that the contact email address provided in the ransom message has been disabled, which means the files are highly unlikely to be recovered by paying the ransom.

If an organisation has backed-up its critical data appropriately then it should generally be possible to restore access to the data without paying a ransom.

Take out Cyber Risk Insurance

As a last step, we recommend taking out Cyber Risk Insurance. There are many varieties of policies varying in cost and cover. There is a cost to hiring IT experts to “de-contaminate” computers and servers and get you back on line again. There is also a chance that money can be stolen, confidential files (that you have a duty to protect) accessed and a loss if income to your business can occur. All included within a policy that is covering these costs to your business. Talk to us today about such a policy and consider this for your protection..

D&O premium pool ‘must treble’ to return to profitability

A new report – called "Show Me The Money!" by insurer XL Catlin and law firm Wotton + Kearney – is the second in a series of three white papers on securities class actions and their impact on the Directors & Officers Liability (D&O) market. The main conclusion is that Directors’ and officers’ (D&O) insurance premiums are under-priced significantly and need to rise strongly to restore profitability. The main risk areas are those exposed to securities class actions, 

It says Directors & Officer's Side A, Side B and Side C cover has been chronically underpriced since at least 2011, while the frequency of class actions is increasing as more plaintiff lawyers and litigation funders enter the space.

The analysis suggests last year’s overall premium pool of about $210 million would need to increase by at least three times to establish a profitable market, if it is assumed all other factors stay unchanged.

“Recent market developments would indicate most D&O insurers are now endeavouring to restore some semblance of profitability to their portfolios after years of market losses,” the report says.
