We normally see malware developing and evolving over the years. One particular malware we've been following is ZeroAccess, which has been continuously improving [since] we first detected it in late 2010.

Case in point: in the latest samples, its self-deletion routine has changed. This is a simple Windows batch file ZeroAccess used to use to remove itself after execution, as a fast and simple way to hide any traces of its presence from the user (click for larger view)...

Some botnets are so big you can see them from space (or at least, Google Earth). Here's what the ZeroAccess botnet looks like in Europe.

Breaking news from Poland today: A variant of the ZeuS trojan is targeting the mobile phone based, two-factor authentication used by ING Bank Slaski.

From the details that we've gathered so far, this appears to be the same type of ZeuS Man-in-the-mobile attack that took place in Spain last year. Spanish security company, S21sec first reported on ZeuS Mitmo here.

ZeuS Ransomware Feature: win_unlock

Earlier today, while doing our daily data mining, we came across a new variant of ZeuS 2.x. It includes a new backdoor command called: win_unlock. Very interesting, turns out this slightly modified ZeuS 2.x includes a ransomware feature.

When this particular variant is executed, it opens Internet Explorer with a specific page (lex.creativesandboxs.com/locker/lock.php) and prevents the user from doing anything else with the infected system. The webpage that was opened presumably showed some type of extortion message, but it's currently unavailable because the site is offline. The most straightforward way to unlock the system is to simply delete the trojan. This can be a bit tricky since the trojan prevents doing anything with the infected system, luckily the locking itself can be easily disabled first.

George Zimmerman's judge must step aside because of bias, a Florida appellate court ruled Wednesday.

The ruling means a new judge will soon preside over Zimmerman's second-degree murder case in the killing of unarmed teenager Trayvon Martin, according to a website set up by Zimmerman's defense team. Zimmerman's lawyer Mark O'Mara filed a motion in July to disqualify Judge Kenneth Lester Jr. But Lester denied the motion, finding it "legally insufficient." O'Mara appealed to Florida's Fifth District Court of Appeal, which disagreed with Lester's finding.

Prosecution star witness Rachel Jeantel, the 19-year-old to whom Trayvon Martin was reportedly speaking while he was being followed by George Zimmerman, admitted again on the stand on Thursday that she had changed her testimony about Zimmerman's words.

Originally, she told police that after Martin asked Zimmerman why he was following him, Zimmerman answered, "What are you talking about?" Later, she changed that to, "What are you doing around here?" As Kathi Belich of WFTV reports, "The first answer could indicate #Zimmermanon9 was not following Martin. The second answer could indicate he was following." Jeantel then testified that she had a friend write a letter to Sybrina Fulton, the mother of Trayvon Martin, stating that Zimmerman had said, "What are you doing around here?" According to Jeantel, the letter was signed "Diamond Eugene." While Jeantel said in testimony that she heard Martin say "get off me," the letter made no mention of that.

Zimmerman Prosecutor Angela Corey Indicted for Allegedly Falsifying Arrest Warrant

The George Zimmerman defense has recently gotten a lucky break.

Angela Corey, Florida's state attorney and the prosecutor against Zimmerman, has been indicted by a citizens' grand jury for allegedly falsifying an arrest warrant and the complaint that led to Zimmerman being charged with the second-degree murder of Trayvon Martin. The indictment accuses Corey of allegedly withholding photographs of Zimmerman's head after the incident. Also, Corey allegedly falsely signed an arrest warrant under oath without including the pictures as evidence. Critics claim that Corey rushed the arrest warrant through because activists were rallying around the Trayvon Martin shooting, demanding that Zimmerman be charged with murder. Critics argue that Corey was attempting to secure a reelection with the support of the activists.
