June 9, 2020

In late May, KrebsOnSecurity alerted numerous officials in Florence, Ala. that their information technology systems had been infiltrated by hackers who specialize in deploying ransomware.

Ukraine Nabs Suspect in 773M Password ‘Megabreach’

May 19, 2020

In January 2019, dozens of media outlets raised the alarm about a new “megabreach” involving the release of some 773 million stolen usernames and passwords that was breathlessly labeled “the largest collection of stolen data in history.” A subsequent review by KrebsOnSecurity quickly determined the data was years old and merely a compilation of credentials pilfered from mostly public data breaches. Earlier today, authorities in Ukraine said they’d apprehended a suspect in the case.

Sipping from the Coronavirus Domain Firehose

April 16, 2020

Security experts are poring over thousands of new Coronavirus-themed domain names registered each day, but this often manual effort struggles to keep pace with the flood of domains invoking the virus to promote malware and phishing sites, as well as non-existent healthcare products and charities.

March 17, 2020

With many people being laid off or working from home thanks to the Coronavirus pandemic, cybercrooks are almost certain to have more than their usual share of recruitable “money mules” — people who get roped into money laundering schemes under the pretense of a work-at-home job offer. Here’s the story of one upstart mule factory that spoofs a major nonprofit and tells new employees they’ll be collecting and transmitting donations for an international “Coronavirus Relief Fund.”

Zyxel Fixes 0day in Network Storage Devices

February 24, 2020

Networking hardware vendor Zyxel today released an update to fix a critical flaw in many of its network attached storage (NAS) devices that can be used to remotely commandeer them. The patch comes 12 days after KrebsOnSecurity alerted the company that precise instructions for exploiting the vulnerability were being sold for $20,000 in the cybercrime underground.

Based in Taiwan, Zyxel Communications Corp. (a.k.a “ZyXEL”) is a maker of networking devices, including Wi-Fi routers, NAS products and hardware firewalls. The company has roughly 1,500 employees and boasts some 100 million devices deployed worldwide. While in many respects the class of vulnerability addressed in this story is depressingly common among Internet of Things (IoT) devices, the flaw is notable because it has attracted the interest of groups specializing in deploying ransomware at scale.

The Hidden Cost of Ransomware: Wholesale Password Theft

January 6, 2020

Organizations in the throes of cleaning up after a ransomware outbreak typically will change passwords for all user accounts that have access to any email systems, servers and desktop workstations within their network. But all too often, ransomware victims fail to grasp that the crooks behind these attacks can and frequently do siphon every single password stored on each infected endpoint. The result of this oversight may offer attackers a way back into the affected organization, access to financial and healthcare accounts, or — worse yet — key tools for attacking the victim’s various business partners and clients.

Secret Service Investigates Breach at U.S. Govt IT Contractor

September 9, 2019

The U.S. Secret Service is investigating a breach at a Virginia-based government technology contractor that saw access to several of its systems put up for sale in the cybercrime underground, KrebsOnSecurity has learned. The contractor claims the access being auctioned off was to old test systems that do not have direct connections to its government partner networks.

In mid-August, a member of a popular Russian-language cybercrime forum offered to sell access to the internal network of a U.S. government IT contractor that does business with more than 20 federal agencies, including several branches of the military. The seller bragged that he had access to email correspondence and credentials needed to view databases of the client agencies, and set the opening price at six bitcoins (~USD $60,000).
