WHOIS Privacy Plan Draws Fire

September 16, 2013

Internet regulators are pushing a controversial plan to restrict public access to WHOIS Web site registration records. Proponents of the proposal say it would improve the accuracy of WHOIS data and better protect the privacy of people who register domain names. Critics argue that such a shift would be unworkable and make it more difficult to combat phishers, spammers and scammers.

‘Yahoo Boys’ Have 419 Facebook Friends

September 11, 2013

Earlier this week, I wrote about an online data theft service that got hacked. That compromise exposed a user base of most young Nigerian men apparently engaged in an array of cybercrime activities — mainly online dating scams and 419 schemes. It turned out that many of these guys signed up for the data theft service using the same email address they used to register their Facebook accounts. Today’s post looks at the social networks between and among these individuals.

Adobe and Microsoft each separately released a raft of updates to fix critical security holes in their software. Adobe pushed patches to plug holes in Adobe Acrobat/Reader and its Flash and Shockwave media players.

Spy Service Exposes Nigerian ‘Yahoo Boys’

September 9, 2013

A crude but effective online service that lets users deploy keystroke logging malware and then view the stolen data remotely was hacked recently. The information leaked from that service has revealed a network of several thousand Nigerian email scammers and offers a fascinating glimpse into an entire underground economy that is seldom explored.

Researchers: Oracle’s Java Security Fails

September 4, 2013

Faced with an onslaught of malware attacks that leverage vulnerabilities and design weaknesses in Java, Oracle Corp. recently tweaked things so that Java now warns users about the security risks of running Java content. But new research shows that the integrity and accuracy of these warning messages can be subverted easily in any number of ways, and that Oracle’s new security scheme actually punishes Java application developers who adhere to it.

Who Built the Syrian Electronic Army?

August 28, 2013

A hacking group calling itself the Syrian Electronic Army (SEA) has been getting an unusual amount of press lately, most recently after hijacking the Web sites of The New York Times and The Washington Post, among others. But surprisingly little light has been shed on the individuals behind these headline-grabbing attacks. Beginning today, I’ll be taking a closer look at this organization, starting with one of the group’s core architects.

Who Wrote the Pincer Android Trojan?

August 27, 2013

Stories in this blog’s Breadcrumbs series have sought to comb through clues that point to the possible location and identities of malware authors and purveyors. But from time to time those clues lead definitively back to an individual. In today’s post, we’ll look at the author of the Pincer Trojan for Android — a 32-year-old programmer at a mobile app development firm in Russia.

How Not to DDoS Your Former Employer

August 20, 2013

Pro tip: If you’re planning to launch a debilitating denial-of-service attack against your former employer, try not to “like” the Facebook page of the DDoS-for-hire Web service that you intend to use in the assault. Tell that to Kevin Courtois, a 28-year-old from Three Rivers, Quebec who was arrested earlier this year for allegedly launching a volley of cyber attacks against his former company over a nine month period beginning in May 2012.

A Closer Look: Perkele Android Malware Kit

August 19, 2013

In March 2013 I wrote about Perkele, a crimeware kit designed to create malware for Android phones that can help defeat multi-factor authentication used by many banks. In this post, we’ll take a closer look at this threat, examining the malware as it is presented to the would-be victim as well as several back-end networks set up by cybercrooks who have been using Perkele to fleece banks and their customers.
