The criminals responsible for launching phishing campaigns that netted dozens of employees and more than 100 computer systems last month at Wipro, India’s third-largest IT outsourcing firm, also appear to have targeted a number of other competing providers, including Infosys and Cognizant — two other large technology consulting companies, new evidence suggests.
Your mobile phone is giving away your approximate location all day long. This isn’t exactly a secret: It has to share this data with your mobile provider constantly to provide better call quality and to route any emergency 911 calls straight to your location. But now, the major mobile providers in the United States — AT&T, Sprint, T-Mobile and Verizon — are selling this location information to third party companies — in real time — without your consent or a court order, and with apparently zero accountability for how this data will be used, stored, shared or protected.
It may be tough to put a price on one’s location privacy, but here’s something of which you can be sure: The mobile carriers are selling data about where you are at any time, without your consent, to third-parties for probably far less than you might be willing to pay to secure it.
One of the more common and destructive computer crimes to emerge over the past few years involves ransomware — malicious code that quietly scrambles all of the infected user’s documents and files with very strong encryption. A ransom, to be paid in Bitcon, is demanded in exchange for a key to unlock the files. Well, now it appears fraudsters are developing ransomware that does the same but for Web sites — essentially holding the site’s files, pages and images for ransom.
A recent Reuters story accusing Russian security firm Kaspersky Lab of faking malware to harm rivals prompted denials from the company’s eponymous chief executive — Eugene Kaspersky — who called the story “complete BS” and noted that his firm was a victim of such activity. But according to interviews with the CEO of Dr.Web — Kaspersky’s main competitor in Russia — both companies experimented with ways to expose antivirus vendors who blindly accepted malware intelligence shared by rival firms.
Last weekend, Target finally disclosed at least one cause of the massive data breach that exposed personal and financial information on more than 110 million customers: Malicious software that infected point-of-sale systems at Target checkout counters. Today’s post includes new information about the malware apparently used in the attack, according to two sources with knowledge of the matter.
An increasing number of malware samples in the wild are using host systems to secretly mine bitcoins. In this post, I’ll look at an affiliate program that pays people for the mass installation of programs that turns host machines into bitcoin mining bots.
Last month’s post examining the top email-based malware attacks received so much attention and provocative feedback that I thought it was worth revisiting. I assembled it because victims of cyberheists rarely discover or disclose how they got infected with the Trojan that helped thieves siphon their money, and I wanted to test conventional wisdom about the source of these attacks.
While the data from the past month again shows why that wisdom remains conventional, I believe the subject is worth periodically revisiting because it serves as a reminder that these attacks can be stealthier than they appear at first glance.
Malicious computer code that leverages a newly-patched security flaw in Oracle’s Java software is set to be deployed later this week to cybercriminal operations powered by the BlackHole exploit pack. The addition of a new weapon to this malware arsenal will almost certainly lead to a spike in compromised PCs, as more than 3 billion devices run Java and many of these installations are months out of date.
Nearly every time I write about a small to mid-sized business that has lost hundreds of thousands of dollars after falling victim to a malicious software attack, readers ask how the perpetrators broke through the victim organization’s defenses, and which type of malware paved the way. Normally, victim companies don’t know or disclose that information, so to get a better idea, I’ve put together a rough profile of the top daily email-based malware attacks over the past month.
The IT director for an international hedge fund received the bad news in a phone call from a stranger: Chinese hackers were running amok on the fund’s network. Not seeing evidence of the claimed intrusion, and unsure of the credibility of the caller, the IT director fired off an email to a reporter.
“So do you think this is legit, or is the guy trying to scare us?” the IT director asked in an email to KrebsOnSecurity.com, agreeing to discuss the incident if he and his company were not named. “He has sent me the logs for the connections to the infected server. I checked the firewall and am not seeing any active connections.”
