If Your Company Is Hacked, Are Your Hackers Still Lurking in Your Network?

If Your Company Is Hacked, Are Your Hackers Still Lurking in Your Network?

When a company falls victim to a cyberattack, one of the most pressing concerns is whether the Information security team was able to eradicate and/or contain the threat completely. In the highly stressful time of post-cyberattack—and during the remediation and recovery phase—company executives are understandably concerned about the possibility that their hacker still lurks somewhere within the company network, just waiting to launch another attack at the first available opportunity.

So what is the process for removing a hacker from the company network once and for all?

Unfortunately, there is no one-size-fits-all solution. Since all data breaches and threats are unique, containment and eradication are different for each company and each event.

Not All Hackers Follow the Same Path—But Certain Hacks Have Tried-and-True Steps You Can Take

Since no two data breaches are the same, each company’s response will ideally be tailored to the company’s particular vulnerabilities—and to the threat environment surrounding the incident itself. In an attack scenario where a hacker gains access to the company network and creates unauthorized administrative accounts and credentials, there are certain incident response tactics that industry experts recommend:

  • Change all passwords over a 24-hour period and ask employees to refrain from accessing the company network and files on personal devices or private mobile networks
  • Simultaneously shutdown and reboot all compromised systems—then wait and watch to see if the hacker or malware resurfaces.

The “persistent threat” scenario illustrates why it is so critical to have a top-notch network threat detection system in place—along with a reputable managed security services provider (MSSP) to help monitor and manage the threat detection software and implement an effective incident response protocol when situations become critical.

In certain cases, password changes and system reboots may only be a temporary solution—and completely disconnecting from the network might be the only option to keep a persistent hacker at bay.

Shutting Down Systems Can Often Interrupt Business for Days, Weeks, or Months At a Time

Shutting down the company network is the last thing any Information Security professional wants to do. Not only does it disrupt business progress, it often costs already vulnerable businesses thousands of dollars per day.

To avoid this expense, most MSSPs will first identify how the hackers accessed the company network, and whether the cyber criminal’s approach set off any threat detection alarms. They will also review network access logs to identify anything anomalous in the system—including the hacker’s digital “fingerprints” and digital signatures. Attack information is often checked against public threat information and private event history to determine if any common hacker traits exist—and if the company has been the victim of the same threat in the past.

Taking a company offline for days—and even weeks—to regain control of company networks is never the optimal solution. Effective threat detection and prevention is necessary to avoid the fallout from shutting down business operations.
