A number of cybercriminal innovations are making it easier for scammers to cash in on your upcoming travel plans. This story examines a recent spear-phishing campaign that ensued when a California hotel had its booking.com credentials stolen. We’ll also explore an array of cybercrime services aimed at phishers who target hotels that rely on the world’s most visited travel website.

Not long ago, the ability to remotely track someone’s daily movements just by knowing their home address, employer, or place of worship was considered a powerful surveillance tool that should only be in the purview of nation states. But a new lawsuit in a likely constitutional battle over a New Jersey privacy law shows that anyone can now access this capability, thanks to a proliferation of commercial services that hoover up the digital exhaust emitted by widely-used mobile apps and websites.

Brazilian authorities reportedly have arrested a 33-year-old man on suspicion of being “USDoD,” a prolific cybercriminal who rose to infamy in 2022 after infiltrating the FBI’s InfraGard program and leaking contact information for 80,000 members. More recently, USDoD was behind a breach at the consumer data broker National Public Data that led to the leak of Social Security numbers and other personal information for a significant portion of the U.S. population.

The U.S. government on Wednesday announced the arrest and charging of two Sudanese brothers accused of running Anonymous Sudan (a.k.a. AnonSudan), a cybercrime business known for launching powerful distributed denial-of-service (DDoS) attacks against a range of targets, including dozens of hospitals, news websites and cloud providers. One of the brothers is facing life in prison for allegedly seeking to kill people with his attacks.

The parents of a 19-year-old Connecticut honors student accused of taking part in a $243 million cryptocurrency heist in August were carjacked a week later, while out house-hunting in a brand new Lamborghini. Prosecutors say the couple was beaten and briefly kidnapped by six young men who traveled from Florida as part of a botched plan to hold the parents for ransom.

Microsoft today released security updates to fix at least 117 security holes in Windows computers and other software, including two vulnerabilities that are already seeing active attacks. Also, Adobe plugged 52 security holes across a range of products, and Apple has addressed a bug in its new macOS 15 “Sequoia” update that broke many cybersecurity tools.

Organizations that get relieved of credentials to their cloud environments can quickly find themselves part of a disturbing new trend: Cybercriminals using stolen cloud credentials to operate and resell sexualized AI-powered chat services. Researchers say these illicit chat bots, which use custom jailbreaks to bypass content filtering, often veer into darker role-playing scenarios, including child sexual exploitation and rape.

A California man accused of failing to pay taxes on tens of millions of dollars allegedly earned from cybercrime also paid local police officers hundreds of thousands of dollars to help him extort, intimidate and silence rivals and former business partners, a new indictment charges. KrebsOnSecurity has learned that many of the man’s alleged targets were members of UGNazi, a hacker group behind multiple high-profile breaches and cyberattacks back in 2012.

The United States today unveiled sanctions and indictments against the alleged proprietor of Joker’s Stash, a now-defunct cybercrime store that peddled tens of millions of payment cards stolen in some of the largest data breaches of the past decade.
