Enlarge (credit: portal gda ) A virulent family of malware that infected more than 10 million Android devices last year has made a comeback, this time hiding inside Google Play apps that have been downloaded by as many as 12 million unsuspecting users. HummingWhale, as the professionally developed malware has been dubbed, is a variant of HummingBad, the name given to a family of malicious apps researchers documented in July invading non-Google app markets . HummingBad attempted to override security protections by exploiting unpatched vulnerabilities that gave the malware root privileges in older versions of Android. Before Google shut it down, it installed more than 50,000 fraudulent apps each day, displayed 20 million malicious advertisements, and generated more than $300,000 per month in revenue. Of the 10 million people who downloaded HummingBad-contaminated apps, an estimated 286,000 of them were located in the US. HummingWhale, by contrast, managed to sneak its way into about 20 Google Play apps that were downloaded from 2 million to 12 million times, according to researchers from Check Point, the security company that has been closely following the malware family for almost a year. Rather than rooting devices, the latest variant includes new virtual machine techniques that allow the malware to perform ad fraud better than ever, company researchers said in a blog post published Monday .

Virulent Android malware returns, gets >2 million downloads on Google Play
“Any student progress from 9:19 to 10:33 a.m. on Friday was not saved…” explained the embarrassed CTO of the educational non-profit Code.org, “and unfortunately cannot be recovered.” Slashdot reader theodp writes: Code.org CTO Jeremy Stone gave the kids an impromptu lesson on the powers of two with his explanation of why The Cloud ate their homework. “The way we store student coding activity is in a table that until today had a 32-bit index… The database table could only store 4 billion rows of coding activity information [and] we didn’t realize we were running up to the limit, and the table got full. We have now made a new student activity table that is storing progress by students. With the new table, we are switching to a 64-bit index which will hold up to 18 quintillion rows of information. The issue also took the site offline, temporarily making the work of 16 million K-12 students who have used the nonprofit’s Code Studio disappear. “On the plus side, this new table will be able to store student coding information for millions of years, ” explains the site’s CTO. But besides Friday’s missing saves, “On the down side, until we’ve moved everything over to the new table, some students’ code from before today may temporarily not appear, so please be patient with us as we fix it.” Read more of this story at Slashdot.
