Microsoft today released software updates to fix at least four dozen security holes in its Windows operating systems and other software, including patches for two zero-day vulnerabilities that are already being exploited in active attacks.

The U.S. Federal Bureau of Investigation (FBI) this week seized 13 domain names connected to “booter” services that let paying customers launch crippling distributed denial-of-service (DDoS) attacks. Ten of the domains are reincarnations of DDoS-for-hire services the FBI seized in December 2022, when it charged six U.S. men with computer crimes for allegedly operating booters.

The U.S. government this week put a $10 million bounty on the head of a Russian man who for the past 18 years operated Try2Check, one of the cybercrime underground's most trusted services for checking the validity of stolen credit card data. U.S. authorities say 43-year-old Denis Kulkov's card-checking service made him at least $18 million, which he used to buy a Ferrari, Land Rover, and other luxury items.

A sprawling online company based in Georgia that has made tens of millions of dollars purporting to sell access to jobs at the United States Postal Service (USPS) has exposed its internal IT operations and database of nearly 900,000 customers. The leaked records indicate the network's chief technology officer in Pakistan has been hacked for the past year, and that the entire operation was created by the principals of a Tennessee-based telemarketing firm that has promoted USPS employment websites since 2016.

A shocking number of organizations -- including banks and healthcare providers -- are leaking private and sensitive information from their public Salesforce Community websites, KrebsOnSecurity has learned. The data exposures all stem from a misconfiguration in Salesforce Community that allows an unauthenticated user to access records that should only be available after logging in.

We learned some remarkable new details this week about the recent supply-chain attack on VoIP software provider 3CX, a complex, lengthy intrusion that has the makings of a cyberpunk spy novel: North Korean hackers using legions of fake executive accounts on LinkedIn to lure people into opening malware disguised as a job offer; malware targeting Mac and Linux users working at defense and cryptocurrency firms; and software supply-chain attacks nested within earlier supply chain attacks.

For the past seven years, a malware-based proxy service known as "Faceless" has sold anonymity to countless cybercriminals. For less than a dollar per day, Faceless customers can route their malicious traffic through tens of thousands of compromised systems advertised on the service. In this post we'll examine clues left behind over the past decade by the proprietor of Faceless, including some that may help put a face to the name.
