Protecting Your Organisation from Social Engineering Attacks: A Guide by ARANKISH
One of the most dangerous—and often ignored—threats to contemporary cyber security is social engineering. At ARANKISH, we have witnessed firsthand how a single successful social engineering attempt can undermine the defences of an entire organisation, resulting in substantial financial loss, harm to the organization’s reputation, and legal repercussions.
This blog post outlines the most common types of social engineering attacks, how to identify them, and – most importantly – how to stop them.
What is Social Engineering?
Social engineering involves tricking people into doing things that allow hackers to gain access to resources, data, or systems. In contrast to technical attacks, social engineering circumvents security measures by taking advantage of human traits like trust, urgency, or curiosity.
Attackers use various channels, including:
- Email (phishing)
- SMS (smishing)
- Voice calls (vishing)
- Instant messaging or social media platforms
How Social Engineering Works
In order to fool users into clicking links, opening attachments, disclosing credentials, sending money, or altering security settings, malicious actors frequently pose as reliable contacts, such as coworkers, managers, clients, or even IT support.
Modern AI tools like deepfakes and voice cloning have made these attacks even more convincing. Attackers can now mimic executives’ voices or generate flawless emails, making social engineering harder to detect than ever before.
Who Is Targeted?
While anyone can be a victim, attackers typically prioritise:
- Senior executives and their assistants
- Finance and HR teams
- System administrators and IT support
- Staff handling external communication (e.g., sales, marketing, legal)
Attackers often cast a wide net, hoping even one user will fall for the scam.
Warning Signs of a Social Engineering Attempt
Here are key red flags to look out for:
1. Unusual Attachments or Links
Even if the message seems familiar, be wary of attachments or links from unfamiliar sources. Before clicking, always confirm with the sender via a reliable method.
2. Urgent Requests Over the Phone (Vishing)
You might feel pressured by impersonators to divulge your credentials or carry out delicate tasks. To sound authentic, they could use AI voice clones or fake caller IDs. Don’t let haste take precedence over verification.
3. Requests to Run Code or Change Settings
Be wary of instructions to enable macros, install software, or bypass organisational policies. These may appear helpful or technical but are often used to deliver malware.
4. Requests for Sensitive Information
Simple requests like, “Can you send me that file again?” or “I’m new to the project, can you share your notes?” could be malicious in disguise. Always assess whether the requester has a genuine need-to-know.
5. Poorly Written or Oddly Worded Messages
Generic greetings, unusual phrasing, or poor grammar can be signs of a phishing attempt. However, don’t rely on this alone – AI-generated scams now appear highly polished.
How to Respond to a Suspected Attack
If you receive a suspicious message or call:
- Do not click, reply, or follow any instructions.
- Report it to your cyber security or IT team immediately.
- Do not delete the message – it may be useful for investigation.
Building a Culture of Vigilance
Organisations must proactively train staff to identify and respond to social engineering threats. ARANKISH recommends:
- Enforcing strong password policies
- Disabling risky features like macros by default
- Implementing multi-factor authentication (MFA)
- Regularly conducting simulated phishing exercises
- Encouraging staff to report anything suspicious without fear of blame
