10 Signs Your Company Might Be Under a Cyberattack

Is your company under cyberattack without even knowing it? From system slowdowns to suspicious emails, here are ten critical warning signs that you might already be compromised. Act fast to protect your business!

In today’s digital age, businesses face relentless cyber threats that can cripple operations, tarnish reputations, and drain resources. The speed at which attackers move means swift detection and response are essential. But how do you know if your company is under attack? Here are ten unmistakable signs that could mean your systems are compromised.

  1. Unexplained Sluggishness in Systems
    One of the first red flags might be a noticeable slowdown in your network or devices. Hackers often use malicious software that drains your company’s resources, causing everything from basic tasks to complex processes to grind to a halt.

  2. Unauthorised Access Attempts
    If you see multiple login attempts, particularly from unknown sources, this could be a major sign that someone is trying to break in. Monitor logs for failed access attempts that clearly indicate possible cyberattack activity.

  3. Strange Network Traffic
    Spikes in traffic that don’t align with regular business hours or geographic locations are a key sign of a potential breach. Often, attackers use your network to transmit data to unfamiliar locations without your consent.

  4. Suspicious Emails from Internal Accounts
    When cybercriminals take control of an employee’s account, they often use it to spread malware or phishing attempts internally. If staff members report receiving odd or unexpected emails from their colleagues, take immediate action.

  5. Disabled Security Software
    One of the first moves hackers make after infiltrating your system is disabling antivirus or firewall programs to avoid detection. If your security measures suddenly go offline without reason, treat it as a high-priority incident.

  6. Unusual File Changes or Deletions
    Files that mysteriously disappear or change without explanation can indicate a cyberattack in progress. Data exfiltration or ransomware attacks often leave traces in your file system that shouldn’t be ignored.

  7. Increased Pop-up Ads
    A flood of pop-up ads, especially on systems that didn’t previously show them, can indicate malware is at work. This type of adware often acts as a gateway for more malicious activities like data theft or system monitoring.

  8. Unexpected Outgoing Communication
    If your network starts sending communications or data to unknown locations, there’s a good chance attackers have taken control. Track any unsanctioned outbound activity and investigate further.

  9. User Complaints of System Malfunctions
    Employees may start noticing their devices behaving strangely—programs crashing, files disappearing, or systems rebooting without warning. These could be signs of underlying cyberattacks aimed at disrupting operations.

  10. Ransom Messages or Threats
    This is perhaps the most blatant sign of a cyberattack. If your organisation receives a ransom message, the attackers have likely already encrypted your critical data. Immediate action is required to assess the scope of the breach and minimise damage.


    What Should You Do?

    If any of these signs seem familiar, time is of the essence. Early detection significantly reduces the damage a cyberattack can cause. Equip your team with the tools to monitor and respond to threats. Regularly update your systems, review your security policies, and ensure you have a robust incident response plan.


    In today’s world, a proactive approach remains your best defence against cybercrime. Stay vigilant, and act fast if you spot any signs that your company might be under attack.
