Developers often rehash the same pieces of code from older projects. As a matter of fact, all good developers and programmers write re-usable codes. If the code is bug-free then using it again saves time and effort. The open source communities consist of novice and expert programmers who create open source codes. Organizations can then reuse the existing codes to perform a new function.
Sadly, this method is not just employed by software developers and other white hats, and cybercriminals to reuse previously used codes that ran properly in the past to build an entirely different threat. Adding fuel to the flames, several such rehashed threats are generated in union with innovative and advanced infection tactics, which makes it harder to secure against.
What’s old is new again
Given the number of various reports being published concerning new threats, it is evident that the web and connected devices at a high-security risk. As a matter of fact, it has been posted by G Data that 22 million new malicious software specimens were recognized in the first quarter of 2017. In other quarters, these statistics imply that approximately 15 new threats are identified every minute.
Even though it is undoubtedly correct that there are a large number of malicious software codes that cybercriminals can access and use, a majority of them are old.
Secplicity stated that a majority of the new malware is really just a cyber version of Frankenstein that is made up of pieces of code that have been stuck together from old malicious software or open source tools. This is how cybercriminals use old codes and tools and recycle them to generate new malware.
What is the motivation behind reusing old malware codes?
Cybercriminals reuse and renovate existing malware to generate new threats. Most of all, this method is time-saving. Rather than writing new code from scratch, it is a lot quicker and simpler just to reuse a segment of code which serves the purpose. Moreover, according to cybersecurity expert Marc Laliberte, cybercriminals save the time in writing new codes to create malicious software and use this time and energy to focus on other essential activities.
He added what the need for reinventing the wheel when some other developer has already constructed a practical solution is. By using old code wherever it is apt, cybercriminals can get the time to concentrate on the remaining aspects such how to bypass malware detection and how to hide attribution.
Reusing top threats
In addition to reusing code to save time, many cybercriminals will also recycle top threats just because they thrived well in the history. Apart from using the same piece of old code for time conservation, several malicious authors also reuse attack methods. Script kiddies or skiddies depend on old tools and attack methods to compensate for their own inadequate skills. Hackers also use old attack methods when the method very efficient.
Securing devices against new and old malware
Since new malware attacks are being generated every day, it is vital that companies take the necessary measures to safeguard themselves and their customers. Investing in good multi-layered protection is a must for every firm, big or small. They must also keep all their software and operating systems up-to-date. Moreover, training employees and the workforce about cyber-security should not be overlooked.
