SITA, a data firm that works with some of the world’s largest airlines, announced Thursday that it had been the victim of a “highly sophisticated cyberattack,” the likes of which compromised information on hundreds of thousands of airline passengers all over the world.

The attack, which occurred in February, targeted data stored on SITA’s Passenger Service System servers, which are responsible for storing information related to transactions between carriers and customers. One of the things SITA does is act as a mechanism for data exchange between different airlines—helping to ensure that passenger “benefits can be used across different carriers” in a systematized fashion.

Understanding what specific data the hackers accessed is, at this point, a little tough—though it would appear that some of it was frequent flier information shared with SITA by members of the Star Alliance, the world’s largest global airline alliance.

An airline alliance is basically an industry consortium, and Star’s membership is comprised of some of the world’s most prominent airlines—including United Airlines, Lufthansa, Air Canada, and 23 others. Of those members, a number have already stepped forward to announce breaches in connection with the attack—and SITA itself would appear to have acknowledged that the affected parties are connected to alliance memberships.

So far, it would appear that the nature of the breach is more wide than deep. That is, a lot of people seem to have been affected, though in most cases the data that was being shared with SITA does not seem that extensive. In the case of Singapore Airlines, for instance, upwards of 500,000 people had their data compromised, though the data did not include things like member itineraries, passwords, or credit card information. The airline has stated:

Around 580,000 KrisFlyer and PPS members have been affected by the breach of the SITA PSS servers. The information involved is limited to the membership number and tier status and, in some cases, membership name, as this is the full extent of the frequent flyer data that Singapore Airlines shares with other Star Alliance member airlines for this data transfer.

Source: Hackers Looted Passenger Data From Some of the Biggest Airlines

Last week, Microsoft announced that the on-premises version of its widely used email and calendaring product Exchange had several previously undisclosed security flaws. These flaws, the company said, were being used by foreign threat actors to hack into the networks of U.S. businesses and governments, primarily to steal large troves of email data. Since then, the big question on everybody’s mind has been: Just how bad is this?

The short answer is: It’s pretty bad

So far, hack descriptors such as “crazy huge,” “astronomical,” and “unusually aggressive” seem to be right on the money. As a result of Exchange vulnerabilities, it is likely that tens of thousands of U.S.-based entities have had malicious backdoors implanted in their systems. Anonymous sources close to the Microsoft investigation have repeatedly told press outlets that somewhere around 30,000 American organizations have been compromised as a result of the security flaws (if correct, these numbers officially dwarf SolarWinds, which led to the compromise of about 18,000 entities domestically and nine federal agencies, according to the White House). The number of compromised entities worldwide could be much larger. A source recently told Bloomberg that there are “at least 60,000 known victims globally.”

Even more problematically, some researchers have said that, since the public disclosure of the Exchange vulnerabilities, it would appear that attacks on the product have only accelerated. Anton Ivanov, a threat research specialist at Kaspersky, said in an email that his team has seen an uptick in activity over the past week.

Microsoft Exchange Server comes in two formats, which has led to some confusion about what systems are at risk: there is an on-premises product and a software-as-a-service cloud product. The cloud product, Exchange Online, is said to be unaffected by the security flaws. As previously stated, it is the on-premises products that are being exploited. Other Microsoft email products are not thought to be vulnerable. As CISA has said, “neither the vulnerabilities nor the identified exploit activity is currently known to affect Microsoft 365 or Azure Cloud deployments.”

There are four vulnerabilities in on-premises Exchange Servers that are actively being exploited (see: here, here, here, and here). Three other security-associated vulnerabilities exist, but authorities say these have not seen active exploitation of these yet (see: here, here, and here.) Patches can be found at Microsoft’s website, though, as we’ll go over in more detail later, there have been some issues with proper deployment.

So far, Microsoft has primarily blamed a threat actor dubbed “HAFNIUM” for the intrusions into Exchange. HAFNIUM is said to be a state-sponsored group

security researchers say it is almost certain that other threat actors are also involved in the exploitation of the vulnerabilities. S

. “Based on our visibility and that of researchers from Microsoft, FireEye, & others, there are at least 5 different clusters of activity that appear to be exploiting the vulnerabilities,” said Red Canary researcher Katie Nickels on Saturday.

Who Is Getting Hit

Due to the widespread use of Exchange, many different types of entities are at-risk. Some large organizations—including the European Banking Authority—have already announced breaches.

[…]

As noted above, Microsoft has issued patches for the vulnerabilities—but these patches have had some problems. On Thursday, a Microsoft spokesperson noted that, in certain cases, the patches would appear to work but wouldn’t actually fix the vulnerability. A full break-down of that issue can be found on Microsoft’s website.

Organizations have been warned that they should not only be patching vulnerabilities but should also be investigating whether they have already been compromised. Microsoft has announced resources to help with that. It issued an update to its Safety Scanner (MSERT) tool which can help identify whether web shells have been deployed against Exchange servers. MSERT is an anti-malware tool that searches for, identifies, and removes malware on a system.

Source: The “Crazy Huge Hack” of Microsoft, Explained

A hacker group claims to have broken into the networks of cloud-based surveillance startup Verkada, gaining unfiltered access to thousands and thousands of live security camera feeds in the process.

The hack first gained public attention Tuesday afternoon, when a Twitter user who goes by the name “Tillie” began leaking purported images of the hack onto the internet: “ever wondered what a @Tesla warehouse looks like?” the hacker quipped, dangling a picture of what appears to be an industrial facility.

Tillie, who goes by the full name Tillie Kottmann and uses they/them pronouns, is allegedly part of an international hacker collective responsible for having breached Verkada, according to a report from Bloomberg. Once inside, the hackers were able to use the firm’s security feeds to peer into the internal workings of droves of organizations, including medical facilities, psychiatric hospitals, jails, schools and police departments, and even large companies like Tesla, Equinox and Cloudflare. The scope of the hack appears massive.

Among other things, Kottmann implied Tuesday that they could have used their access to Verkada to hack into the laptop of Cloudflare CEO Matthew Prince:

The hacker group has very noticeably courted public attention, calling the intrusion campaign “Operation Panopticon” and claiming they want to “end surveillance capitalism” by bringing attention to the ways in which ubiquitous surveillance dominates people’s lives.

[…]

According to Bloomberg, “Arson Cats” gained entry to the company via a pretty massive security blunder: The hackers discovered a password and username for a Verkada administrative account publicly exposed to the internet. In a Twitter message, Tillie reiterated this to Gizmodo, claiming that once they had compromised the administrator account (called a “super administrator”), they were able to hook into any of the 150,000 video feeds in Verkada’s library.

“The access we had allowed us to impersonate any user of the system and access their view of the platform,” said the hacker, further explaining that the “superadmin rights are also what granted us access to the root shell at the click of a button.”

n the latest in a string of “hits” on Russian dark web forums, the prominent crime site Maza appears to have been hacked by someone earlier this week.

This is kind of big news since Maza (previously called “Mazafaka”) has long been a destination for all assortment of criminal activity, including malware distribution, money laundering, carding (i.e., the selling of stolen credit card information), and lots of other bad behavior. The forum is considered “elite” and hard to join, and in the past, it has been a cesspool for some of the world’s most prolific cybercriminals.

Whoever hacked Maza netted thousands of data points about the site’s users, including usernames, email addresses, and hashed passwords, a new report from intelligence firm Flashpoint shows. Two warning messages were then scrawled across the forum’s home page: “Your data has been leaked” and “This forum has been hacked.”

KrebsOnSecurity reports that the intruder subsequently dumped the stolen data on the dark web, spurring fears among criminals that their identities might be exposed (oh, the irony). The validity of the data has been verified by threat intelligence firm Intel 471.

This hack comes shortly after similar attacks on two other Russian cybercrime forums, Verified and Exploit, that occurred earlier this year. It’s been noted that the successive targeting of such high-level forums is somewhat unusual.
