Hard to believe it’s time to celebrate another go ’round the Sun for KrebsOnSecurity! Today marks exactly seven years since I left The Washington Post and started this here solo thing. And what a remarkable year 2016 has been!
InterContinental Hotels Group (IHG), the parent company for more than 5,000 hotels worldwide including Holiday Inn, says it is investigating claims of a possible credit card breach at some U.S. locations.
A decade ago, if a desktop computer got infected with malware the chief symptom probably was an intrusive browser toolbar of some kind. Five years ago you were more likely to whacked by a banking trojan that stole all your passwords and credit card numbers. These days if your mobile or desktop computer is infected what gets installed is likely to be “ransomware” — malicious software that locks your most prized documents, songs and pictures with strong encryption and then requires you to pay for a key to unlock the files.
New research suggests that an elaborate cybercrime ring is responsible for stealing between $3 million and $5 million worth of revenue from online publishers and video advertising networks each day. Experts say the scam relies on a vast network of cloaked Internet addresses, rented data centers, phony Web sites and fake users made to look like real people watching short ad segments online.
Many readers are asking what they should be doing in response to Yahoo’s disclosure Wednesday that a billion of its user accounts were hacked. Here are a few suggestions and pointers, fashioned into a good old Q&A format.
Just months after disclosing a breach that compromised the passwords for a half billion of its users, Yahoo now says a separate incident has jeopardized data from at least a billion more user accounts. The company also warned attackers have figured out a way to log into targeted Yahoo accounts without even supplying the victim’s password.
Both Adobe and Microsoft on Tuesday issued patches to plug critical security holes in their products. Adobe’s Flash Player patch addresses 17 security flaws, including one “zero-day” bug that is already actively being exploited by attackers. Microsoft’s bundle of updates tackles at least 42 security weaknesses in Windows and associated software.
Federal investigators in the United States and Europe last week arrested nearly three-dozen people suspected of patronizing so-called “booter” services that can be hired to knock targeted Web sites offline. The global crackdown is part of an effort by authorities to weaken demand for these services by impressing upon customers that hiring someone to launch cyberattacks on your behalf can land you in jail.
The accused ringleader of a cyber fraud gang that allegedly rented out access to a criminal cloud hosting service known as “Avalanche” is now a fugitive from justice following a bizarre series of events in which he shot at Ukrainian police, was arrested on cybercrime charges and then released from custody.
New research published this week could provide plenty of fresh fodder for Mirai, a malware strain that enslaves poorly-secured Internet of Things (IoT) devices for use in powerful online attacks. Researchers in Austria have unearthed a pair of backdoor accounts in more than 80 different IP camera models made by Sony Corp. Separately, Israeli security experts have discovered trivially exploitable weaknesses in approximately 500,000 white-labeled IP camera models that are not currently sought out by Mirai.
