Paper: How It Works: Steganography Hides Malware in Image Files

Posted by Martijn Grooten on Apr 28, 2016

The Virus Bulletin Virus Prevalence Table, which ran from 1992 until 2013, gave users a regular snapshot of what was really going on in the virus (and later malware) world, recording the number of incidents of each virus reported to VB in the preceding month. In August 2000, Denis Zenkin, a self-confessed virus prevalence table junkie, shared his findings following a study of the virus prevalence tables over the preceding few years, allowing him to determine the top ten viruses of the period, the top viruses by type and the viruses of the year.

Security researcher Andreas Lindh recently found a vulnerability in Apache OpenMeetings that could allow remote code execution on a vulnerable server. Andreas reported the vulnerability to the OpenMeetings developers and, once it had been patched, he wrote up the details.

Word and Excel’s internal file formats used to be something in which few were interested – until macro viruses came along and changed all that. In 1996, Andrew Krukov provided an overview of the new breed of viruses.

Despite the profitability of ransomware there is a good reason why mining malware is thriving

Though ransomware is far more profitable than using a compromised PC to mine bitcoins, the global distribution of malware means that there are many botnets for which mining is the most efficient way to extract money out of a PC.
When, a few years ago, a friend and I were analysing a rather large botnet and we saw some network traffic indicating that it was engaged in Bitcoin mining, we felt rather… https://www.virusbulletin.com/blog/2017/09/despite-profitability-ransomware-there-good-reason-why-mining-malware-thriving/
