Lesson 2: Data can be stolen in minutes

[relemedf5w023]

Unknown ransomware variants are particularly common. The latest generation of malware, such as Locky and TeslaCrypt, is written specifically to evade detection by modern security systems. As a result, antivirus and other signature-based solutions are no longer sufficient to combat them. In addition to antivirus, companies today need to use tools and technologies that block suspicious content by analyzing its behavior and sources, rather than signatures. Advanced multi-layered threat prevention solutions are not just a nice-to-have for complete security assurance, they are an absolute necessity.

Verizon's 2016 Breach Investigations Report found that the armenia whatsapp data from a network breach to data theft can last minutes, not hours or days as previously thought. Zero-day exploits, which cybercriminals prefer to create unknown threats, are also evolving rapidly. Companies can no longer simply recognize malware; they need to stop it before it penetrates the network. Suitable solutions for this include, for example, sandboxes for testing incoming traffic. A sandbox is a test isolated environment in which you can open a suspicious file and see how it behaves. If it exhibits suspicious activity, the system blocks it. Thanks to sandboxes, malicious content disguised as seemingly innocent files can be identified in time.

It is also very important to examine the corporate IT infrastructure. Segmenting the network can prevent cybercriminals from moving within the perimeter and minimize damage if an attack does occur.

Lesson 3: Employees are the weakest link
Phishing and social engineering have become even more popular in 2016. Many of the largest cyberattacks began with social engineering, such as the theft of 21 million records from the US Office of Personnel Management. Advanced phishing attacks can be very convincing: hackers force employees to voluntarily hand over personal information or login credentials. As a result, cybercriminals can move freely within a corporate network, leaving virtually no trace of malicious activity. One such attack recently cost Leoni AG, Europe’s largest supplier of wires and electrical cables, $40 million. Employees of any level can be targeted by hackers. Errors and human error cannot be completely eliminated, but regular information security training can significantly reduce the risk of a successful attack.
