Information Security Report – March 2018


Current Threats and Exploits


  • Crypto Miners Are Sneaking To Your Networks – Despite dropping off a little in the news this month, crypto currency is still a much sought after commodity for many. Attackers are looking to cash in on this to do anything possible in order to make good use of your idle CPU time. In the past we have seen malware, advertising, worms and phishing campaigns aiming to deploy mining scripts or software on unsuspecting victims. It was recently reported that a large number of websites around the world were hijacked with crypto mining scripts as a result of a compromised plugin script. As a result of this, users visiting the site were redirected to execute coinhive mining scripts for the attacker, and although this method is used by advertisers to monetise sites, the incident highlighted the importance of knowing your online supply chain (and where you get your web resource scripts from).
  • Shortened URLs In Phishing – It has been observed in the wild that shortened URLs are increasingly being used again by active phishing campaigns. As a result of this, one of the core user awareness points for phishing of looking at the link is bypassed as most users will recognise and trust shortened URL services (such as Google and Bitly). Typically seen in campaigns targeting web mail credentials, this attack vector poses a significant risk to organisations and emphasises the importance of web content filtering. It is also recommended that users are made aware to be on the lookout for this type of activity.
  • Memcache Denial of Service Attacks – A huge number of Denial of service attacks are being staged from misconfigured internet facing memcache servers. These severs accept easily forged udp packets and this makes them perfect for reflected and amplified denial of service attacks. As this service was not designed to be exposed to the internet it is unlikely that any additional security will be configured, the remediation is to firewall off this service from the internet.

  • Importance of Multifactor Authentication In the Modern Enterprise – Multifactor authentication is a practical way to add security to the logon process by requiring multiple forms of identification as an addition to the username/password sequence. As the number of password exploits continue to increase, enterprises should look into available multifactor tools and integrate them into their infrastructure so as to secure logins and access to resources.
