Microsoft on Tuesday issued a bevy of patches to correct at least 70 distinct security vulnerabilities in Windows and software designed to interact with various flavors of the operating system. This month’s patch batch tackles some notable threats to enterprises — including multiple flaws that were publicly disclosed prior to Patch Tuesday. It also bundles fixes to quash threats relevant to end users, including critical updates for Adobe Flash Player and Microsoft Office, as well as a zero-day bug in Internet Explorer.

Email provider VFEmail has suffered what the company is calling “catastrophic destruction” at the hands of an as-yet unknown intruder who trashed all of the company’s primary and backup data in the United States. The firm’s founder says he now fears some 18 years’ worth of customer email may be gone forever.

A highly targeted, malware-laced phishing campaign landed in the inboxes of multiple credit unions last week. The missives are raising eyebrows because they were sent only to specific anti-money laundering contacts at the credit unions, and many credit union sources say they suspect the non-public data may have been somehow obtained from the National Credit Union Administration (NCUA), an independent federal agency that insures deposits at federally insured credit unions.

Prosecutors in Northern California have charged two men with using unauthorized SIM swaps to steal and extort money from victims. One of the individuals charged allegedly used a hacker nickname belonging to a key figure in the underground who’s built a solid reputation hijacking mobile phone numbers for profit.

According to indictments unsealed this week, Tucson, Ariz. resident Ahmad Wagaafe Hared and Matthew Gene Ditman of Las Vegas were part of a group that specialized in tricking or bribing representatives at the major wireless providers into giving them control over phone numbers belonging to people they later targeted for extortion and theft.

Godaddy.com, the world’s largest domain name registrar, recently addressed an authentication weakness that cybercriminals were using to blast out spam through legitimate, dormant domains. But several more recent malware spam campaigns suggest GoDaddy’s fix hasn’t gone far enough, and that scammers likely still have a sizable arsenal of hijacked GoDaddy domains at their disposal.

More than 250 customers of a popular and powerful online attack-for-hire service that was dismantled by authorities in 2018 are expected to face legal action for the damage they caused, according to Europol, the European Union’s law enforcement agency.

In April 2018, investigators in the U.S., U.K. and the Netherlands took down attack-for-hire service WebStresser[.]org and arrested its alleged administrators. Prior to the takedown, the service had more than 151,000 registered users and was responsible for launching some four million attacks over three years.

Now, those same authorities are targeting people who paid the service to conduct attacks.

The Justice Department has filed criminal charges against three U.S. men accused of swatting, or making hoax reports of bomb threats or murders in a bid to trigger a heavily armed police response to a target’s address. Investigators say the men, aged 19 to 23, all carried out the attacks with the help of Tyler Barriss, a convicted serial swatter whose last stunt in late 2018 cost an Oklahoma man his life.

FBI agents on Wednesday arrested Neal Patel, 23, of Des Plaines, Ill. and Tyler Stewart, 19 of Gulf Breeze, Fla. The third defendant, Logan Patten, 19, of Greenwood, Mo., agreed to turn himself in. The men are charged in three separate indictments with conspiracy and conveying false information about the use of explosive devices.

The ongoing partial U.S. federal government shutdown is having a tangible, negative impact on cybercrime investigations, according to interviews with federal law enforcement investigators and a report issued this week by a group representing the interests of FBI agents. Even if lawmakers move forward on new proposals to reopen the government, sources say the standoff is likely have serious repercussions for federal law enforcement agencies for years to come.

One federal agent with more than 20 years on the job told KrebsOnSecurity that the shutdown “is crushing our ability to take the fight to cyber criminals.”

Two of the most disruptive and widely-received spam email campaigns over the past few months — including an ongoing sextortion email scam and a bomb threat hoax that shut down dozens of schools, businesses and government buildings late last year — were made possible thanks to an authentication weakness at GoDaddy.com, the world’s largest domain name registrar, KrebsOnSecurity has learned.

Perhaps more worryingly, experts warn this same weakness that let spammers hijack domains registered through GoDaddy also affects a great many other major Internet service providers, and is actively being abused to launch phishing and malware attacks which leverage dormant Web site names currently owned and controlled by some of the world’s most trusted corporate names and brands.

My inbox and Twitter messages positively lit up today with people forwarding stories from Wired and other publications about a supposedly new trove of nearly 773 million unique email addresses and 21 million unique passwords that were posted to a hacking forum. A story in The Guardian breathlessly dubbed it “the largest collection ever of breached data found.” But in an interview with the apparent seller, KrebsOnSecurity learned that it is not even close to the largest gathering of stolen data, and that it is at least two to three years old.
