Spear Phishing

11 Apr 2019, MOQdigital Marketing


Cisco Campaign (9)Phishing is a form of cyber attack that has been around for some time. Generally, appearing in email format, hackers can use phishing to disguise themselves as a trusted source to acquire sensitive information from users. These users may click on what appears to be an authentic link or file and infect their computer with malware, spyware, ransomware, bots, viruses, and more. In the past, phishing was widespread, with hackers aiming for quantity instead of quality with their attacks. Over time, these attacks became more sophisticated, appearing more legitimate and disguised as commonly trusted sources such as banks and companies, rather than from strangers seeking to distribute their family fortune. Spear phishing is a step up from this – with hackers utilising a sophisticated, trusted disguise but operating in a significantly more targeted manner. These messages usually contain personal information and are difficult to identify as malicious. They are also more sinister in nature, with hackers using spear phishing to obtain specific sets of information – such as access to corporate files.

 What businesses need to know

The threat of spear phishing can be monumental for a company, with data breaches costing millions in costs and fines, not to mention the potential damage to a business’s reputation. One single attack could put an entire company at risk, and successful attacks often go unnoticed – increasing the potential for continued losses. Any personal information that exists online can be used as bait for spear phishing attacks. The more authentic the threat appears the more likely a user is to enter their information, click on a link, or open a file. Attackers will research their targets, utilising social media to create a trustworthy profile. This may take the form of a bank the user frequents, or the name of a colleague, or even an address from a former place of employment. Spear phishing attacks rely on the appearance of validity and will build their messages around this. Instead of targeting multiple sources, they will hone in on one or two – usually people with high levels of company access.

 Protecting against Phishing

It is difficult for companies to avoid phishing attacks entirely, but some steps can be taken to reduce their risk. These include:

  • Utilising web filtering to obtain visibility and control of content  on and off corporate networks
  • Ensure that users only have access to the files they need. Understand who has access to what, whether that access is relevant, and authenticate appropriate administrative controls.
  • Apply email security solutions and threat protection that can detect potentially fraudulent emails and links, and block them before they impact the company
  • Educate employees on how to identify phishing attacks, as well as what to do if they discover a breach within the system. A robust security strategy will help companies reduce their risk – and reduce the impact of a threat once it occurs.
