Cryptojacker Campaign Hits MikroTik Routers

More than 200,000 routers hit with a sophisticated cryptomining attack that appears to be spreading.

In March, routers from Latvian manufacturer MikroTik were hit by an advanced threat dubbed Operation Slingshot. The company patched for the threat, but now a new cryptomining attack has hit MikroTik routers and appears to be spreading rapidly.

The original Operation Slingshot campaign was spyware that was able to gather screenshots, keyboard data, network data, passwords, various desktop activity, the clipboard, and more without ever using a zero-day exploit. Instead, the attack took advantage of two modules that were able to implant themselves in a targeted router. Those modules were accompanied by very sophisticated detection evasion techniques that included shutting down the attack if certain forensic activities were detected. Nevertheless, the attack was discovered and countered.

This time around, researchers have found a new MikroTik-targeting cryptojacking campaign that began with routers in Brazil and is now spreading beyond those borders. The campaign, which injects cryptomining software into traffic transiting an infected MikroTik router, was so successful that the performance hit was what drew attention to the attack; the threat actor then shifted strategies to only inject the miner through router-based error pages.

According to researchers at Trustwave, the attack has now hit more than 200,000 routers, with the number still growing as of this writing. Further, tens of thousands of those routers are outside Brazil, indicating that any initial geographic targeting is no longer in effect.

"Everyone with a MikroTik router should be worried that they will be targeted no matter where they reside," says Karl Sigler, threat intelligence manager at Trustwave. Fortunately, those same global users have a meaningful response possible for the attack.

"Hopefully with enough coverage, users of MikroTik routers will patch their devices, Sigler adds. "A single patch [available since April] is enough to stop this exploitation in its tracks."

This is not the first time MikroTik owners have been urged to patch and reboot their routers. MikroTik equipment was specifically mentioned in the FBI's May 2018 call for router reboots, and even the March attack was effective only against routers that were not up to date with software patches.
