MA-665.062017: MyCERT Special Alert – Festive Season and Holiday Alert
 
Date published: 15/06/2017


1.0 Introduction

As the festive season holiday approaches and many of us will be leaving for holiday break, we would like to alert System Administrators and Internet users to ensure sufficient measures had been implemented to secure their systems and networks before leaving for the holidays.

There had been several incidents recently and we had produced Alerts and Advisories on these issues such as Ransomware Targeting MongoDB and Elastic Search, Microsoft Addresses Shadow Broker Exploits, WannaCry Ransomware and Circulation of Recent Hoax Messages. Other than that, we also produced advisories on software or product updates such as Wordpress, Windows Vista, Drupal, OpenSSL, Google and etc.

Thus, with the release of these Alerts and Advisories, we hope security incidents could be prevented and minimized to a certain extent with preventive measures in place.

System Administrators should take extra precautions against any possibilities of intrusions, phishing attacks, and malware activities such as ransomware during the festive season, by implementing proper preventive measures against the threats. Data Centres and Web Hosting Companies should also take extra precautions against any software or third party add-ons they're running by applying the latest patches or upgrades to prevent intrusions that may exploit unpatched applications.

Financial Institutions must also be vigilant against any possibilities of phishing and fraudulent activities that target Internet banking. Customers must be advised adequately on avoiding themselves becoming victims of phishing and fraudulent activities by applying safe browsing, safe email practice and safe Internet banking practice. Organizations must ensure contact information of System Administrators is made available in the event of a security incident that occurs at or originate from your site.

System Administrators and Internet users must be aware of these threats and vulnerabilities by applying necessary patches and updates by referring to MyCERT released on Alerts and Advisories on current threats and vulnerabilities.

Attached below are some recommendations for System Administrators:

1. Make sure systems, applications and third party add-ons are updated with latest upgrades and security patches.

If you're running older versions of operating systems or software, make sure they are upgraded to the latest versions as older versions may have some vulnerability that can be manipulated by intruders. Aside from that, please make sure that your web based applications and network based appliances are patched accordingly.

4. Make sure loggings of systems and servers are always enabled.

5. Perform regular backups of all critical information to limit the impact of data or system loss and to help expedite the recovery process. Ideally, the backup must be done daily, on a separate media and stored offline at an alternate site.

6. Organizations are recommended to apply defense in depth strategy in protecting their networks. Firewalls, intrusion prevention systems (IPS), network and host based intrusion detection systems (IDS) can prevent and log most of the generic attacks.
