Krebs on Security

Microsoft today released updates to fix at least 86 security vulnerabilities in its Windows operating systems and other software, including a weakness in all supported versions of Windows that Microsoft warns is actively being exploited. The software giant also has made a controversial decision to put the brakes on a plan to block macros in Office documents downloaded from the Internet.

Twice in the past month KrebsOnSecurity has heard from readers who've had their accounts at big-three credit bureau Experian hacked and updated with a new email address that wasn't theirs. In both cases the readers used password managers to select strong, unique passwords for their Experian accounts. Research suggests identity thieves were able to hijack the accounts simply by signing up for new accounts at Experian using the victim's personal information and a different email address.

On December 7, 2021, Google announced it had sued two Russian men allegedly responsible for operating the Glupteba botnet, a global malware menace that has infected millions of computers over the past decade. That same day, AWM Proxy -- a 14-year-old anonymity service that rents hacked PCs to cybercriminals -- suddenly went offline. Security experts had long seen a link between Glupteba and AWM Proxy, but new research shows AWM Proxy's founder is one of the men being sued by Google.

Authorities in the United States, Germany, the Netherlands and the U.K. last week said they dismantled the "RSOCKS" botnet, a collection of millions of hacked devices that were sold as "proxies" to cybercriminals looking for ways to route their malicious traffic through someone else's computer. While the coordinated action did not name the Russian hackers allegedly behind RSOCKS, KrebsOnSecurity has identified its owner as a Russian man living abroad who also runs the world's top Russian spamming forum.

Microsoft on Tuesday released software updates to fix 60 security vulnerabilities in its Windows operating systems and other software, including a zero-day flaw in all supported Microsoft Office versions on all flavors of Windows that's seen active exploitation for at least two months now. On a lighter note, Microsoft is officially retiring its Internet Explorer (IE) web browser, which turns 27 years old this year.

Cybercrime groups that specialize in stealing corporate data and demanding a ransom not to publish it have tried countless approaches to shaming their victims into paying. The latest innovation in ratcheting up the heat comes from the ALPHV/BlackCat ransomware group, which has traditionally published any stolen victim data on the Dark Web. Today, however, the group began publishing individual victim websites on the public Internet, with the leaked data made available in an easily searchable form.

A 33-year-old Illinois man was sentenced to two years in prison today following his conviction last year for operating services that allowed paying customers to launch powerful distributed denial-of-service (DDoS) attacks against hundreds of thousands of Internet users and websites.

On the eve of their federal criminal trial for allegedly stealing vast swaths of Internet addresses for use in large-scale email spam campaigns, three current or former executives at online advertising firm Adconion Direct have agreed to plead guilty to lesser misdemeanor charges of fraud and misrepresentation via email.

Netflix has a new documentary series airing next week -- "Web of Make Believe: Death, Lies & the Internet" -- in which Yours Truly apparently has a decent amount of screen time. The debut episode explores the far-too-common harassment tactic of "swatting" -- wherein fake bomb threats or hostage situations are phoned in to police as part of a scheme to trick them into visiting potentially deadly force on a target’s address.
