Piriform CCleaner and Avast Servers Hacked

-

Piriform, developer of PC maintenance tool CCleaner, announced it was breached by hackers who infected an estimated 2 million users with malware. Piriform says the incident has since been resolved, but encourages users to update the software to prevent


The malware, discovered by security researchers at Cisco Talos, accompanied downloads of certain versions of CCleaner. Luckily, not every CCleaner user is affected by the malware breach. “This compromise only affected customers with the 32-bit version of the v5.33.6162 of CCleaner and the v1.07.3191 of CCleaner Cloud,” said the company in a statement addressing the breach. “No other Piriform or CCleaner products were affected.
Piriform’s parent company, Avast said that updating CCleaner to its latest version, 5.34, removes the offending malware, while users of CCleaner Cloud should already have received a software update addressing the issue.

How to verify your downloaded files using MD5 Checksum on Windows?

-

MD5 stands for Message Digest version 5 . The MD5 algorithm takes a file (the “message”) of any size, and reduces it down to a code that looks like this: “ac30ce5b07b0018d65203fbc680968f5″ (the “digest”). The brilliant thing about the MD5 algorithm is that if the message changes by so much as a single byte, it will produce a completely different digest. An MD5 sum is a string of letters and numbers that acts like a fingerprint for a file. If two files have the same MD5 sum, the files are exactly alike - which is why MD5 "fingerprints" can verify whether or not your downloaded file got corrupted in transit, hence it is used to verify the integrity of files, as virtually any change to a file will cause its MD5 hash to change. MD5 digests have been widely used in the software world to provide some assurance that a transferred file has arrived intact. For example, file servers often provide a pre-computed MD5 (known as md5sum) checksum for the files, so that a user can compare th...

The World of Technology

Without technology, our lives wouldn't be just the usual walk in the park daily routine. Technology is a huge contributor to the well being of human kind. Just try to imagine how hard it would be to make it through the day without the simplest of technologies. We have grown by using the luxuries that technology provides that many wouldn't know how to adapt to the traditional and simpler methods. Technology has surely proven itself to be very beneficial, if not necessary. Some people may be confused on what exactly technology is? Technology is the systematic study of the methods and techniques employed in industry, research, agriculture, and commerce. These studies are then put to use in order to make daily life much easier. Some might think that technology is not necessary due to the opinion that it brings out the worst in people. The earliest technologies of all time are said to be made during the Paleolithic Era. When these technologies were made, language was a key factor in...

How to check your anti-virus is working or not using anti-malware testfile?

-

Say, you want to test your anti-virus program on your PC. Using real viruses for testing in the real world is rather like setting fire to the dustbin in your office to see whether the smoke detector is working. Such a test will give meaningful results, but with unappealing, unacceptable risks. Since it is unacceptable for you to send out real viruses for test or demonstration purposes, you need a file that can safely be passed around and which is obviously non-viral, but which your anti-virus software will react to as if it were a virus. The good news is that such a test file already exists. A number of anti-virus researchers have already worked together to produce a file that their (and many other) products "detect" as if it were a virus. It's called EICAR.COM anti malware testfile. It is also short and simple - in fact, it consists entirely of printable ASCII characters, so that it can easily be created with a regular text editor. So, without any further ado, lets get d...
