Packed themida virus

It generally shows up after the provoking procedures on your computer — opening the suspicious e-mail messages, clicking the advertisement in the Web or installing the program from suspicious resources. From the instance it appears, you have a short time to do something about it until it starts its destructive action. And be sure — it is better not to wait for these harmful actions. BRQ is ransomware-type malware. It looks for the documents on your computer, encrypts it, and then asks you to pay the ransom for getting the decryption key.

Besides making your documents inaccessible, this malware also does a ton of harm to your system. It changes the networking settings in order to stop you from reading the removal tutorials or downloading the anti-malware program. BRQ can additionally block the launching of anti-malware programs. Ransomware has been a horror story for the last 4 years. It is difficult to imagine a more dangerous virus for both individuals and corporations. To hack it with a brute force, you need more time than our galaxy currently exists, and possibly will exist.

However, that virus does not do all these terrible things instantly — it can require up to several hours to cipher all of your documents. BRQ detection is a clear signal that you must start the removal process. BRQ spreading are typical for all other ransomware variants.

Those are one-day landing sites where users are offered to download and install the free program, so-called bait e-mails and hacktools. Bait e-mails are a relatively new method in malware distribution — you receive the e-mail that imitates some normal notifications about shipments or bank service conditions changes.

Inside of the email, there is a corrupted MS Office file, or a web link which leads to the exploit landing site. Malicious email message. This one tricks you to open the phishing website. Avoiding it looks quite uncomplicated, however, still demands a lot of recognition. Such ransomware are a type of malware that is specified by on-line frauds to require paying the ransom money by a sufferer.

In most instances, the ransom note will come up when the customer restarts the PC after the system has currently been harmed. IL expands by leaps as well as bounds. Nevertheless, the ransom money notes and also tricks of extorting the ransom money quantity may differ depending upon particular local local setups. The ransom money notes as well as methods of obtaining the ransom money amount might vary depending on specific local regional setups.

The alert after that demands the customer to pay the ransom. In nations where software piracy is less preferred, this technique is not as efficient for the cyber scams. IL popup alert might falsely declare to be originating from a police establishment and also will certainly report having located youngster porn or various other prohibited data on the gadget. IL popup alert might wrongly declare to be obtaining from a regulation enforcement institution and also will certainly report having situated child pornography or various other prohibited information on the gadget.

The alert will in a similar way contain a requirement for the customer to pay the ransom. The is an excellent way to deal with recognizing and removing threats — using Gridinsoft Anti-Malware. This program will scan your PC, find and neutralize all suspicious processes. When setup file has finished downloading, double-click on the setup-antimalware-fix. IL files and other malicious programs.

This process can take a minutes, so I suggest you periodically check on the status of the scan process.

If this is a false-positive, then I indeed think there is some problem, especially for the company using Themida. CDreier , Sep 12, Joined: Jul 21, Posts: , Location: Texas.

The problem is that everyone loses. First, our corporation would have to stop recommending NOD32 to our customers if this can't be resolved we have been recommending it for some time now. We would hurt due to lost sales for the products out there that are flagged. Rafael would be hurt because the more this type of thing occurs the more likely it could remove such a good product from the market.

Kneejerk reactions are not good. From a technical point of view, in the future, if detection is a must, then NOD32 should possibly not flag it in such a way to be as alarming as it looks now. In this case Themida is only detected when the customer selects potentially unwanted application detection from NOD32 options. But when it reports, it reports just the same as a virus.

Last edited: Sep 14, Niklass , Sep 14, Flyfan, Niklass, But there are a few elements not discussed And of course no matter what happens before the file is executed, it is simply an inanimate object, like a piece of paper.

Bytes do nothing. If the writer uses any packer from any company, it will no longer be detected in a disk scan because its byte order has changed unless the the anti-virus product knows how to detect and unpack such files.

But still it is in byte form and all that needs to be done is for the AV vendor to update their definitions. This is because it may still be the same virus packed, but it's byte order has simply changed with a packer there may be 's of packers out there. I do not think it is possible for the core bytes to mutate AND still be packed by Themida, so in a sense, this is actually a small security benefit unless such packer was on the users system.

For the longer term this will be a good practice because it will surely come up again with any developer tool that all the sudden becomes used by a virus writer.

Yes, you are correct. One may not be able to reverse-engineer the files, if this is precisely important to the AV company. But if I understand correctly, reverse engineering a virus is not the only method to determine a virus? One could do a system watch, and see what changes occur. If every virus had to be reverse engineered, I do not think updates to definitions could come as quick.

So, if a virus is identified, one could use the part of the bytes for the definitions, and that is where Rafael could work with the AV companies out there. There will always be packers, protectors, obfuscators, out there. Especially with Dotnet code which is not as strong against reverse engineering as past unmanaged code. So with this, how do AV products and executable code that is processed by another program exist together?
