SEO Expert Hired and Fired By Ashley Madison Turned on Company, Promising Revenge

This post was originally published on this site[This is Part II of a story published here last week on reporting that went into a new Hulu documentary series on the 2015 Ashley Madison hack.] It was around 9 p.m. on Sunday, July 19, when I received a message through the contact form on KrebsOnSecurity.com that the marital infidelity website AshleyMadison.com had been hacked. The message contained links to confidential Ashley Madison documents, and included a manifesto that said a hacker group calling itself the Impact Team was prepared to leak data on all 37 million users unless Ashley Madison and […]

Top Suspect in 2015 Ashley Madison Hack Committed Suicide in 2014

This post was originally published on this siteWhen the marital infidelity website AshleyMadison.com learned in July 2015 that hackers were threatening to publish data stolen from 37 million users, the company’s then-CEO Noel Biderman was quick to point the finger at an unnamed former contractor. But as a new documentary series on Hulu reveals [SPOILER ALERT!], there was just one problem with that theory: Their top suspect had killed himself more than a year before the hackers began publishing stolen user data. The new documentary, The Ashley Madison Affair, begins airing today on Hulu in the United States and on […]

Who’s Behind the DomainNetworks Snail Mail Scam?

This post was originally published on this siteIf you’ve ever owned a domain name, the chances are good that at some point you’ve received a snail mail letter which appears to be a bill for a domain or website-related services. In reality, these misleading missives try to trick people into paying for useless services they never ordered, don’t need, and probably will never receive. Here’s a look at the most recent incarnation of this scam — DomainNetworks — and some clues about who may be behind it. The DomainNetworks mailer may reference a domain that is or was at one […]

Russian Cybersecurity Executive Arrested for Alleged Role in 2012 Megahacks

This post was originally published on this siteNikita Kislitsin, formerly the head of network security for one of Russia’s top cybersecurity firms, was arrested last week in Kazakhstan in response to 10-year-old hacking charges from the U.S. Department of Justice. Experts say Kislitsin’s prosecution could soon put the Kazakhstan government in a sticky diplomatic position, as the Kremlin is already signaling that it intends to block his extradition to the United States. Nikita Kislitsin, at a security conference in Russia. Kislitsin is accused of hacking into the now-defunct social networking site Formspring in 2012, and conspiring with another Russian man […]

U.K. Cyber Thug “PlugwalkJoe” Gets 5 Years in Prison

This post was originally published on this siteJoseph James “PlugwalkJoe” O’Connor, a 24-year-old from the United Kingdom who earned his 15 minutes of fame by participating in the July 2020 hack of Twitter, has been sentenced to five years in a U.S. prison. That may seem like harsh punishment for a brief and very public cyber joy ride. But O’Connor also pleaded guilty in a separate investigation involving a years-long spree of cyberstalking and cryptocurrency theft enabled by “SIM swapping,” a crime wherein fraudsters trick a mobile provider into diverting a customer’s phone calls and text messages to a device […]

SMS Phishers Harvested Phone Numbers, Shipment Data from UPS Tracking Tool

This post was originally published on this siteThe United Parcel Service (UPS) says fraudsters have been harvesting phone numbers and other information from its online shipment tracking tool in Canada to send highly targeted SMS phishing (a.k.a. “smishing”) messages that spoofed UPS and other top brands. The missives addressed recipients by name, included details about recent orders, and warned that those orders wouldn’t be shipped unless the customer paid an added delivery fee. In a snail mail letter sent this month to Canadian customers, UPS Canada Ltd. said it is aware that some package recipients have received fraudulent text messages […]

Why Malware Crypting Services Deserve More Scrutiny

This post was originally published on this site If you operate a cybercrime business that relies on disseminating malicious software, you probably also spend a good deal of time trying to disguise or “crypt” your malware so that it appears benign to antivirus and security products. In fact, the process of “crypting” malware is sufficiently complex and time-consuming that most serious cybercrooks will outsource this critical function to a handful of trusted third parties. This story explores the history and identity behind Cryptor[.]biz, a long-running crypting service that is trusted by some of the biggest names in cybercrime. Virtually all […]

Microsoft Patch Tuesday, June 2023 Edition

This post was originally published on this siteMicrosoft Corp. today released software updates to fix dozens of security vulnerabilities in its Windows operating systems and other software. This month’s relatively light patch load has another added bonus for system administrators everywhere: It appears to be the first Patch Tuesday since March 2022 that isn’t marred by the active exploitation of a zero-day vulnerability in Microsoft’s products. June’s Patch Tuesday features updates to plug at least 70 security holes, and while none of these are reported by Microsoft as exploited in-the-wild yet, Redmond has flagged several in particular as “more likely […]

Barracuda Urges Replacing — Not Patching — Its Email Security Gateways

This post was originally published on this siteIt’s not often that a zero-day vulnerability causes a network security vendor to urge customers to physically remove and decommission an entire line of affected hardware — as opposed to just applying software updates. But experts say that is exactly what transpired this week with Barracuda Networks, as the company struggled to combat a sprawling malware threat which appears to have undermined its email security appliances in such a fundamental way that they can no longer be safely updated with software fixes. The Barracuda Email Security Gateway (ESG) 900 appliance. Campbell, Calif. based […]

Service Rents Email Addresses for Account Signups

This post was originally published on this siteOne of the most expensive aspects of any cybercriminal operation is the time and effort it takes to constantly create large numbers of new throwaway email accounts. Now a new service offers to help dramatically cut costs associated with large-scale spam and account creation campaigns, by paying people to sell their email account credentials and letting customers temporarily rent access to a vast pool of established accounts at major providers. The service in question — kopeechka[.]store — is perhaps best described as a kind of unidirectional email confirmation-as-a-service that promises to “save your […]

Ask Fitis, the Bear: Real Crooks Sign Their Malware

This post was originally published on this siteCode-signing certificates are supposed to help authenticate the identity of software publishers, and provide cryptographic assurance that a signed piece of software has not been altered or tampered with. Both of these qualities make stolen or ill-gotten code-signing certificates attractive to cybercriminal groups, who prize their ability to add stealth and longevity to malicious software. This post is a deep dive on “Megatraffer,” a veteran Russian hacker who has practically cornered the underground market for malware focused code-signing certificates since 2015. One of Megatraffer’s ads on an English-language cybercrime forum. A review of […]

This post was originally published on this siteThe number of phishing websites tied to domain name registrar Freenom dropped precipitously in the months surrounding a recent lawsuit from social networking giant Meta, which alleged the free domain name provider has a long history of ignoring abuse complaints about phishing websites while monetizing traffic to those abusive domains.

Re-Victimization from Police-Auctioned Cell Phones

This post was originally published on this site Countless smartphones seized in arrests and searches by police forces across the United States are being auctioned online without first having the data on them erased, a practice that can lead to crime victims being re-victimized, a new study found. In response, the largest online marketplace for items seized in U.S. law enforcement investigations says it now ensures that all phones sold through its platform will be data-wiped prior to auction. Researchers at the University of Maryland last year purchased 228 smartphones sold “as-is” from PropertyRoom.com, which bills itself as the largest […]

Feds Take Down 13 More DDoS-for-Hire Services

This post was originally published on this site 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.

A researcher found DC Health had five Salesforce Community sites exposing data. Salesforce Community is a widely-used cloud-based software product that makes it easy for organizations to quickly create websites. Customers can access a Salesforce Community website in two […]

3CX Breach Was a Double Supply Chain Compromise

This post was originally published on this siteWe learned some remarkable new details this week about the recent supply-chain attack on VoIP software provider 3CX. The lengthy, complex intrusion has all 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. Researchers at ESET say this job offer from a phony HSBC recruiter on LinkedIn was North Korean malware masquerading […]
