Baldr is the name of a new family of information-stealing malware. Its authors first introduced it to cybercriminal circles in January, and about a month later, Microsoft’s security team reported that they have seen it in the wild. Bill Gates’ specialists said that the stealer is ‘highly obfuscated’ which usually suggests that someone has put a fair amount of effort into creating something powerful. Read More

When a site gets compromised, the attackers will often leave some piece of malware behind to allow them access back to the site. Hackers want to leave a door open to retain control of the website and to reinfect it continuously. This type of malware is called a backdoor.Backdoors are types of malware that allow for remote control of a compromised website by bypassing appropriate authentication methods.Even after updating a site, changing its passwords, and doing other post-hack procedures, the backdoor might not be removed. Leaving a backdoor in a website allows it to be accessed unexpectedly.Even though there are backdoors written in all languages, the ones we see the most are done in PHP.Read More
In two-way communication, wherever a frame is received, the receiver waits and does not send the control frame (acknowledgment or ACK) back to the sender immediately. The receiver waits until its network layer passes in the next data packet. The delayed acknowledgment is then attached to this outgoing data frame. This technique of temporarily delaying the acknowledgment so that it can be hooked with the next outgoing data frame is known as piggybacking.Read More
