With so many other high-profile cases of phishing schemes in the news, such as the 2018 DNC hack and 2016 Russian election meddling, it's no wonder insider threats keep security personnel up at night. After one employee clicked the links, malware provided hackers with remote access to computers in the network and access to personally identifiable information - all the tools needed for identity theft. Links to malware in a targeted spear phishing email campaign began in 2014 and went undetected for months. In 2017, health insurance company Anthem paid $115 million in a class-action lawsuit after a record-breaking number of customers' data was left vulnerable because of a security breach. Spyware and viruses are examples of malware. Malicious software, also known as malware, can steal, encrypt or delete private information, monitor computer activity without user permission or alter core computing function of the device. The resulting spyware installation allows the employee's device to be remotely monitored while granting hackers' access to messages, calendars, contacts and its microphone. Last year, Amnesty Internal became a victim of the Pegasus spyware when an employee clicked on a rigged WhatsApp message. Users can take preventative measures by reading terms and conditions before installing software, avoiding pop-up ads and only downloading software from trusted sources. To prevent spyware, network administrators should require remote workers to access resources over a network through a virtual private network that includes a security scan component. Without antispyware tools, spyware can be difficult to detect. Adware, Trojans and keystroke loggers are all examples of spyware. Any software installed on a device without the end user's permission is classified as spyware, even if it is downloaded for a harmless purpose. Basic antivirus programs scan files for the presence of malicious software, allow users to schedule automatic scans and remove any malicious software. Though specifically created to eliminate viruses, antivirus software can also aid against spyware, adware and other malicious software. Antivirus software is designed to detect, remove and prevent malware infections on a device or network. The city of Akron, Ohio, suffered a virus attack in January 2019 that was traced back to ransomware set off after two employees opened fake invoices sent through spam emails.Īntivirus. To become infected, someone must purposely or accidentally spread the infection. A computer virus is malignant code that can steal passwords, spam contacts, corrupt files, log keystrokes and even take over the infected device. Use this as starting point for developing an IRP for your company's needs. Your Editable Incident Response Plan (IRP) Template The following are some key terms to remember when considering how to prevent computer security threats from insiders. Simple mistakes such as clicking rigged links in emails, messaging apps and advertisements invite hackers to surveil companies and organizations with massive consequences. Employees can unwittingly sabotage systems and create computer security threats through sheer ignorance. A pair of Chase Manhattan Bank employees stole credit card numbers, which they used to steal nearly $100,000.A computer programmer for North Carolina-based Lance, angered over a demotion, planted a logic bomb that took field sales reps' computers offline for days.A worker in GTE's Network Service Support Center in Tampa, Fla., wiped data and caused more than $200,000 in damage.The DOJ's list of computer intrusion cases is a litany of inside jobs. The result can be sabotaged systems, destroyed data, stolen credit card information, etc. Insiders are typically subject to very few controls - organizations tend to rely on trust rather than any sort of technical or procedural countermeasures. In a revealing report, the Department of Justice's Office of the Inspector General cited not Hanssen's brilliance as a spy, but rather the bureau's failure to implement and enforce strong insider security procedures as a prime reason for his success over 20 years. Institutional laxity invites insider problems. It makes sense: They have intimate knowledge of our network layouts, applications, staff and business practices. While most of our attention is focused on internet-based attacks, insiders cause the vast majority of security incidents and can do the most damage. We've gotten pretty good at protecting our perimeters, but most of us do a less-than-adequate job protecting our enterprises from employees (current and former), business partners, contractors, interns and even customers.
