Vulnerable routers from MikroTik have been misused to form what cybersecurity researchers have called one of the largest botnet-as-a-service cybercrime operations seen in recent years.  According to a new piece of research published by Avast, a cryptocurrency mining campaign leveraging the new-disrupted  Glupteba botnet  as well as the infamous TrickBot malware were all distributed using the same command-and-control (C2) server. "The C2 server serves as a botnet-as-a-service controlling nearly 230,000 vulnerable MikroTik routers," Avast's senior malware researcher, Martin Hron,  said  in a write-up, potentially linking it to what's now called the Mēris botnet. The botnet is known to exploit a known vulnerability in the Winbox component of MikroTik routers ( CVE-2018-14847 ), enabling the attackers to gain unauthenticated, remote administrative access to any affected device. Parts of the Mēris botnet were  sinkholed  in late  September 2021 . ...

A security researcher has just discovered a stealthy cryptocurrency-mining malware that was also using Windows SMB vulnerability at least two weeks before the outbreak of WannaCry ransomware attacks. According to Kafeine, a security researcher at Proofpoint , another group of cyber criminals was using the same EternalBlue exploit , created by the NSA and dumped last month by the Shadow Brokers, to infect hundreds of thousands of computers worldwide with a cryptocurrency mining malware called ' Adylkuzz .' This malicious campaign went unnoticed for weeks because unlike WannaCry , this malware does not install ransomware or notify victims, but instead, it quietly infects unpatched computers with malware that only mine ' Monero ,' a Bitcoin-like cryptocurrency. This Malware Saves Computers From Getting Hacked By WannaCry The Researcher believes Adylkuzz malware attack could be larger in scale than WannaCry ransomware attack because it has been designed to blo...

Vulnerability Management (VM) has long been a cornerstone of organizational cybersecurity. Nearly as old as the discipline of cybersecurity itself, it aims to help organizations identify and address potential security issues before they become serious problems. Yet, in recent years, the limitations of this approach have become increasingly evident.  At its core, Vulnerability Management processes remain essential for identifying and addressing weaknesses. But as time marches on and attack avenues evolve, this approach is beginning to show its age. In a recent report, How to Grow Vulnerability Management into Exposure Management (Gartner, How to Grow Vulnerability Management Into Exposure Management, 8 November 2024, Mitchell Schneider Et Al.), we believe Gartner® addresses this point precisely and demonstrates how organizations can – and must – shift from a vulnerability-centric strategy to a broader Exposure Management (EM) framework. We feel it's more than a worthwhile read an...

The Bitcoin mining rig is becoming a popular alternative to people who want an easy way to earn the digital currency. All you have to do is plug the hardware that specializes in Bitcoin mining and run its customized software. After that, you can sit back and relax as it mines the digital currency for you. A popular eSports league has admitted that one of its employees harnessed the power of member's computers without their knowledge in order to mine Bitcoins. For a period of 2 weeks, gamers noticed that their computers were generating unusually high GPU loads and frequent BSOD errors. Some gamers stated that their GPUs were damaged due to them reaching temperatures above 90 degrees Celsius. The mining began on April 13th and affected thousands of gamers, who unwittingly mined over $3,700 worth of the currency. Eric Thunberg, co-owner of ESEA, stated that the Bitcoin miner was meant to be part of an April Fools joke, however, they weren't able to finish it in time. Th...
