Computer crooks and spammers are abusing a little-known encoding method that makes it easy to disguise malicious executable files (.exe) as relatively harmless documents, such as text or Microsoft Word files.
CAPTCHAs, those squiggly and frustrating puzzles that many Web sites require users to solve before registering or leaving comments, are designed to block automated activity and deter spammers. But for some Russian-language forums that cater to spammers and other miscreants, CAPTCHAs may also be part of a vetting process designed to frustrate foreign newbie hackers and investigators.
Criminals who operate large groupings of hacked PCs tend to be a secretive lot, and jealously guard their assets against hijacking by other crooks. But one of the world’s largest and most sophisticated botnets is openly renting its infected PCs to any and all comers, and has even created a Firefox add-on to assist customers.
An international cybercrime gang stole $13 million from a Florida-based financial institution earlier this year, by executing a highly-coordinated heist in which thieves used ATMs around the globe to cash out stolen prepaid debit cards, KrebsOnSecurity has learned.
Earlier this year, Russian police arrested Dmitry Stupin, a man known in hacker circles as “SaintD.” Stupin was long rumored to be the right-hand man of Igor Gusev, the alleged proprietor of GlavMed and SpamIt, two shadowy sister organizations that until this time last year were the largest sources of spam touting rogue Internet pharmacies.
According to several sources who are familiar with the matter, Russian police pulled Stupin off of a plane before it left Moscow. The police also reportedly took Stupin’s MacBook and copied its contents. The police detained Stupin as part of an investigation into Gusev launched nearly a year ago. Gusev fled his native Moscow last year and has not returned.
Sometime in the past few days, more than four years’ worth of chat conversations — apparently between Stupin, Gusev and dozens of other GlavMed employees — were leaked. Those conversations offer a fascinating glimpse into the day-to-day operations one of the world’s largest organization cyber criminal organizations.
I recently wrote about an online service that was selling access to stolen credit and debit card data. That post received a lot of attention, but criminal bazaars are a dime a dozen. The real news is that few of these fraud shops are secure enough to keep their stock of stolen data from being pilfered by thieves.
Six million Web pages have been booby-trapped with malware, using security vulnerabilities in software that hundreds of thousands of e-commerce Web sites use to process credit and debit card transactions. Web security firm Armorize said it has detected more than… Read More »
On Wednesday I wrote that many of the top fake antivirus distribution programs had ceased operations, citing difficulty in processing credit card transactions from victims. Others are starting to take note of the trend: Security firm McAfee says it has witnessed a dramatic drop in the number of customers reporting scareware detections in recent weeks.
A majority of the largest fake AV affiliate programs that pay hackers to foist junk security software have closed up shop in recent weeks. The wave of closures comes amid heightened scrutiny of the industry from security experts and a host of international law enforcement officials.
Over the past several weeks, many of the Web sites for the top fake AV promotion programs disappeared or complained of difficulty in processing credit card transactions for would-be scwareware victims: Fake AV brands such as Gagarincash, Best AV, Blacksoftware.cc and a Sevantivir.com ceased operating or alerted peddlers who were hired to install these programs that they might not get paid for current and future installations.
Cyber attacks designed to knock Web sites off line happen every day, yet shopping for a virtual hit man to launch one of these assaults has traditionally been a dicey affair. That’s starting to change: Hackers are openly competing to… Read More »
