However, one thing is for certain and that is you must make sure to quickly find a way to eliminate CopperStealer if it is currently within your computer or else there could be many unpleasant unforeseen consequences that could arise from this malware attack. Below, we will tell you about some of the possible ways a Trojan horse could be used to cause harm and after that, we will explore some of the methods used for distributing this kind of malware. Last but not least, at the end of the article, we will provide you with a removal guide that will allow you to locate and remove from your PC everything related to CopperStealer.

The CopperStealer Malware

It oftentimes depends on the specific situation when it comes down to how the CopperStealer malware infection would be utilized. A common consequence of the CopperStealer malware attack would be corruption and damage to user files or to the system itself.

However, usually damaging your computer or data isn’t the primary goal of the people behind threats like CopperStealer and Wup.exe. Instead, they might try to use the virus to spy on your activities or to take over your computer and then force it to carry out different tasks that would benefit the hackers. Some examples of such tasks are mining of cryptocurrencies, spreading spam messages, and participating in large-scale coordinated DDoS attacks. In all those cases, the user is likely to notice a severe slow-down of the computer as well as frequent crashes, freezes, software unresponsiveness, and other similar stability issues.

As we already mentioned, a Trojan could spy on you and secretly collect personal data from your machine. This data could be used by the hackers to steal money from you, harass you, or to blackmail you. Another way a Trojan horse like CopperStealer could be used for blackmailing you (this time indirectly) is when it inserts a Ransomware in your system that can encrypt your data, thereby keeping you from accessing it until you carry out a ransom payment.

The Copper Stealer Malware

Faithful to it name, the Copper Stealer malware infection is usually disguised as something that users wouldn’t initially see as dangerous. One of the most effective ways to disguise the Copper Stealer malware is when the threat is made to look like an expensive program or game that is being distributed for free so that users would be tempted to download it.

In most cases, such programs can be found uploaded to pirate sites and that is why hackers oftentimes use such sites to spread disguised Trojans. Two other common ways for spreading such threats are spam messages and misleading click bait adverts so be sure to avoid those as well so that you don’t land more Trojans in the future.

      HKEY_CURRENT_USER—-Software—Microsoft—-Windows—CurrentVersion—Run– Random
      HKEY_CURRENT_USER—-Software—Microsoft—Internet Explorer—-Main—- Random
