We’re celebrating our one-year anniversary here at F5 Labs, the application threat intelligence division of F5! Although F5 researchers have been providing threat-related, F5-specific guidance to our customers for many years through DevCentral, the time was right a year ago today to launch a dedicated website that provides the general public with vendor-neutral, application-focused, actionable…
Read MoreEvery day, your web servers are increasingly being scanned—and likely attacked—by adversaries attempting to gain access to your infrastructure. Between 2015 and 2017, our data partner, Loryka, observed these types of scans grow from 200 per minute to as much as 2,000 per minute. These kinds of attackers are professionals; they do this for a…
Read MoreLast week, a malware campaign targeting Jenkins automation servers was reported by CheckPoint researchers.1 The attackers exploited a deserialization vulnerability2 in Jenkin’s bidirectional channel (CVE-2017-1000353)3 to deploy Monero cryptomining malware that generated an estimated profit of $3 million. Following this disclosure, F5 researchers observed what appears to be the same threat actor group, as they…
Read MoreF5 threat researchers detected attackers actively exploiting the rTorrent client through a previously undisclosed misconfiguration vulnerability and deploying a Monero (XMR) crypto-miner operation. The rTorrent client misconfiguration vulnerabilities include: No authentication required for XML-RPC communication Sensitive XML-RPC method is allowed (direct OS command execution) Attackers are actively exploiting this vulnerability in the wild by scanning…
Read MoreLast week, F5 threat researchers spotted a Monero (XMR) crypto-mining campaign that was taking advantage of a user configuration vulnerability in the rTorrent client, specifically misconfigured XML-RPC functionality. This misconfiguration vulnerability in rTorrent allows an unauthenticated user to execute methods in the rTorrent client using HTTP requests. After deeper analysis of the attack logs, F5…
Read MoreFigure 2: Latest attack request targeting Windows servers As shown in Figure 2, the latest attack requests are targeting the same URL, keeping the same HTTP header values and the same exploit structure, however, they are now using Windows shell commands to download and execute a file. Using the Windows certutil Tool While Linux…
Read MoreThere’s a lot of speculation in cryptocurrency right now. People are mining coins all over the place, and even though it’s getting harder and harder to make money mining coins, interest is still high. All it costs is money for the power bill. So, of course, clever people are figuring out how to use other people’s power…
Read MoreF5 researchers recently noticed a new campaign exploiting a vulnerability in Microsoft Internet Information Services (IIS) 6.0 servers (CVE–2017–7269) in order to mine Electroneum crypto-currency. Last year, ESET security researchers reported that the same IIS vulnerability was abused to mine Monero, and install malware to launch targeted attacks against organizations by the notorious “Lazarus” group.…

Figure 14: Statistics of the Monero mining payment address belonging to the attacker The attacker has earned 8.76 Monero coins by now,4 with a current price of 110.79 USD per a Monero coin,5 which totals to 970.52 USD. According to the information provided on the mining server website, this operation began around June 1.…
